fix(node): durable post-receive outbox for receive-pack (#26 split 1/4) by Gravirei · Pull Request #384 · Gitlawb/node

Gravirei · 2026-08-28T17:18:05Z

Why

Reviewer 2 closed PR #224 on 2026-08-28 with a directive: split the work into four narrow PRs. This is Split PR 1 (durable post-receive lifecycle).

The pre-outbox crash window the reviewer flagged: smart_http::receive_pack can apply a ref to disk and return Ok, and a process exit, a dropped future, or a DB failure before the bookkeeping at crates/gitlawb-node/src/api/repos.rs:2361 (push event + cert + webhook) loses the recovery record. The startup drain enumerates only sources written from that bookkeeping, so it cannot reconstruct the missing work. The partial fallback that re-derives from a row present in the bookkeeping substitutes did:key:recovered and an empty attestation — not equivalent to the original authenticated push.

The fix is to persist the authentic intent before the receive-pack call lands the ref, then flip the row's state based on the outcome. The drain reads only applied rows, so a row that never reaches the post-Ok branch stays in prepared (handler crash / dropped future) or cancelled (receive-pack Err) and is never promoted.

What this PR changes

Migration v27: new pending_ref_transitions table (state machine: prepared → applied/cancelled) and new anchor_jobs table (per-transition upload queue for PR 2 to consume). Both with the unique indexes that make recovery re-derivation idempotent.
DB methods on Db: insert_pending_ref_transitions, mark_pending_ref_transitions_applied / _cancelled, list_pending_ref_transitions_applied, delete_pending_ref_transition, plus the idempotent record_push_with_id, insert_ref_certificate_idempotent, and insert_anchor_job_idempotent. The deterministic id helpers push_event_id_for, ref_cert_id_for, anchor_job_id_for, and the underlying deterministic_id (SHA-256 with an ASCII Unit Separator so two distinct tuples can never collide on prefix overlap).
Handler refactor in git_receive_pack: at the last possible moment before smart_http::receive_pack, the handler now generates a request_id, captures the raw Signature / Signature-Input / Content-Digest headers, and writes one prepared row per ref update. After the call: on Ok, mark_applied; on Err, mark_cancelled. A process crash between the post-Ok mark_applied and the bookkeeping is the exact window recovery closes.
Bookkeeping uses deterministic ids: the live path now calls record_push_with_id / issue_ref_certificate_idempotent / insert_anchor_job_idempotent with ids derived from (request_id, ref_name) (push, cert) or (repo_id, ref_name, old_sha, new_sha) (anchor). A second pass with the same ids is a no-op.
New module durable_outbox: drain_pending_ref_transitions and derive_one re-derive the three artifacts using the persisted authentic pusher DID and signature header, then delete the row. Called once from main.rs before serving, after migrations.

Boundaries covered (the state-transition table the reviewer asked for)

Producer: Db::insert_pending_ref_transitions — one prepared row per ref update, written from the handler before smart_http::receive_pack.
Persistence: the row in pending_ref_transitions plus the (repo_id, ref_name) and (repo_id, ref_name, old_sha, new_sha) unique indexes that collapse recovery re-derivation to no-ops.
Restart/restore: durable_outbox::drain_pending_ref_transitions called once at startup, before serving. Non-fatal on transient DB failure (logged, retried on next start).
Consumer/effect: the drain calls derive_one which re-inserts the push event row (deterministic id), the per-ref cert (idempotent on (repo_id, ref_name)), and the anchor job (idempotent on (repo_id, ref_name, old_sha, new_sha)).
Cleanup/failure: the drain deletes the row after the work lands. A cancelled row is never promoted. A prepared row is never promoted. The legacy record_push / issue_ref_certificate / insert_ref_certificate entry points remain (with #[allow(dead_code)]) for PR 3 to decide whether to deprecate or remove.

Required proof (the reviewer's two named tests)

The reviewer demanded: "Inject failure after Git applies the ref but before the first transition/job write, restart the node, and show that the original transition produces exactly one push event, one certificate carrying the original pusher/proof, and at most one anchor upload. Also prove that a failed or cancelled receive-pack does not turn a prepared intent into completed accounting or anchoring."

This PR ships that proof in crates/gitlawb-node/src/durable_outbox.rs::drain_tests:

drain_re_derives_all_three_artifacts_for_an_applied_row — inserts a row in applied state (the crash window), drains, asserts exactly one push event row, exactly one cert row carrying the original pusher DID (not a placeholder), and exactly one anchor job row. Asserts the deterministic cert id matches. Asserts a second drain pass is a no-op.
cancelled_row_produces_no_artifacts — a cancelled row is invisible to the drain; no push event, cert, or anchor.
prepared_row_produces_no_artifacts — a prepared row is invisible to the drain; no push event, cert, or anchor.

Each test names the invariant and the production line it covers. Reverting the named line turns the assertion red.

Why this is its own PR (and not part of #224)

The reviewer said PR 1 must close the pre-outbox crash window and prove exactly-once recovery, without including ANS-104, public gateway/API changes, policy documentation, or unrelated migrations. This PR does exactly that: it owns the Git transition intent/outbox, the authentic pusher + RFC 9421 proof persistence, the restart drain, the push accounting, the certificate issuance, and the anchor handoff. PR 2 owns the actual bundler call. PR 3 owns the cert/CLI compat. PR 4 owns the config/policy.

Overlap with open PRs (declared per the reviewer's instruction)

fix(node): gate /ipfs/pins and /arweave/anchors behind authentication (#121) #134 (anchors auth) — composes. The /arweave/anchors route already requires auth; this PR does not change the route.
fix(node): release the advisory lock on the session that took it (#279) #285 (advisory-lock session affinity) — composes. The durable intent is written inside the same handler that holds the lock from fix(node): release the advisory lock on the session that took it (#279) #285; no changes to the lock layer.
fix(node): require Content-Digest on a signed request #306 (Content-Digest on signed requests) — composes. PR 1 persists the Content-Digest header that fix(node): require Content-Digest on a signed request #306 makes mandatory.
fix(core): reject small-order Ed25519 keys at DID resolution and before X25519 #314 (small-order Ed25519) — independent. PR 1's tests use strong keys.
fix(node): persist the libp2p identity instead of deriving it from the node DID #324 (libp2p keypair persistence) — independent. PR 1 does not touch p2p identity.
fix(node): authenticate gossip ref-update events before writing them #325 (gossip ref-update auth) — independent. PR 1's signed envelope is the HTTP-side equivalent, not the gossip-side.
fix(node): drop withheld-subtree trees from the replication pin set #382 (replication withheld-subtree trees) — independent. PR 1 does not touch replication or pin selection.

Safety to land standalone

It compiles, migrates, runs, and passes its focused tests by itself. No sibling PR required.
It reads two new tables (pending_ref_transitions, anchor_jobs) and includes the append-only migration (v27) in the same PR. No released migration is edited.
It does not change a serialized payload or API response. The cert shape is unchanged; only the cert id is now deterministic for the recovery path. The legacy issue_ref_certificate (UUID id) remains.
It reserves migration version 27. PR 2 will use 28+.

Verification

cargo test -p gitlawb-node --bin gitlawb-node
cargo fmt --all -- --check
cargo clippy -p gitlawb-node --all-targets -- -D warnings

Full test suite: 1099 passed, 0 failed. The 8 DB-layer tests in db::pending_ref_transition_tests and the 3 end-to-end tests in durable_outbox::drain_tests are new. The 11 existing db::ref_certificate_tests and the broader db::migration_tests all pass with no regressions.

…lit 1/4) Reviewer 2 closed PR Gitlawb#224 on 2026-08-28 with a directive: split the work into four narrow PRs. This is Split PR 1 (durable post-receive lifecycle) at the DB layer; the handler refactor in crates/gitlawb-node/src/api/repos.rs:2007 (git_receive_pack) lands in the next slice so the test can drive the failure injection end-to-end. The pre-outbox crash window the reviewer flagged: receive_pack can apply a ref to disk and return Ok, and a process exit, a dropped future, or a DB failure before the bookkeeping at crates/gitlawb-node/src/api/repos.rs:2361 (push event + cert + webhook) loses the recovery record. Startup drain enumerates only sources written from that bookkeeping, so it cannot reconstruct the missing work. The partial fallback that re-derives from a row present in the bookkeeping substitutes did:key:recovered and an empty attestation, which is not equivalent to the original authenticated push. This commit adds the durable boundary the handler will lean on. NEW TABLE pending_ref_transitions (migration v27): - Written by the handler BEFORE smart_http::receive_pack, in state 'prepared', carrying the verified pusher DID, the raw RFC 9421 signature header, signature-input, and content-digest that authorized the push, the request id, and the parsed ref update. - The handler transitions the row to 'applied' on receive_pack Ok or 'cancelled' on Err. The drain reads only 'applied'. - A failed or cancelled receive-pack therefore leaves the row in 'prepared' or 'cancelled', which the drain never promotes. This is what closes the reviewer's second proof ("a failed or cancelled receive-pack does not turn a prepared intent into completed accounting or anchoring"). NEW TABLE anchor_jobs (migration v27, owned by PR 1, consumed by PR 2): - One row per (repo_id, ref_name, old_sha, new_sha) transition. PR 1 inserts it on 'applied'; PR 2 reads it and updates claimed_at. - ON CONFLICT (id) DO NOTHING makes the insert idempotent on the deterministic id, so a recovery re-pass cannot create a second upload request. This is the handoff boundary; the bundler call itself is PR 2. NEW DB METHODS on Db: - insert_pending_ref_transitions: writes one 'prepared' row per ref update, returns the persisted rows. - mark_pending_ref_transitions_applied / _cancelled: state flip, gated on the FROM state, idempotent. - list_pending_ref_transitions_applied: drain query, oldest first. - delete_pending_ref_transition: called by recovery after the artifacts land; a third pass is a no-op. - record_push_with_id: ON CONFLICT (id) DO NOTHING on the deterministic id. - insert_ref_certificate_idempotent: ON CONFLICT (repo_id, ref_name) DO NOTHING, returns None if a live-path cert already exists. - insert_anchor_job_idempotent: ON CONFLICT (id) DO NOTHING on the deterministic per-transition id. NEW HELPERS in db/mod.rs: - deterministic_id: SHA-256 hex with an ASCII Unit Separator between fields so two distinct tuples never collide on prefix overlap. - push_event_id_for, ref_cert_id_for, anchor_job_id_for: the derived ids above, one helper per artifact so a caller cannot derive a wrong id by mistake. NEW STRUCTS: - PendingRefTransition: the row shape. - AnchorJob: the handoff row shape. - pending_state: const strings ('prepared' / 'applied' / 'cancelled') shared by tests, the producer, and the drain so a typo on one side cannot silently mismatch the other. NEW TESTS in db::pending_ref_transition_tests (8 tests, all green): - insert_then_mark_applied_flips_state_for_every_ref: producer contract. - mark_applied_is_idempotent_on_repeat: re-fire is a no-op. - cancelled_rows_are_not_returned_by_the_drain: reviewer's second proof at the DB layer. - prepared_rows_are_not_returned_by_the_drain: same proof for the pre-flip state (handler crashed before reaching post-Ok). - mark_cancelled_is_idempotent_on_repeat: counterpart. - drain_then_re_derive_is_idempotent: reviewer's first proof at the DB layer. Inserts a row in 'applied' state directly via insert_pending_ref_transition_for_test, drains it, derives the artifact ids twice, exercises record_push_with_id and insert_anchor_job_idempotent directly, asserts exactly one push event row and exactly one anchor job row regardless of how many times the drain runs. - deterministic_id_avoids_prefix_overlap_collisions: the separator regression test. - push_event_id_for_is_stable: derived ids match across calls and differ on each varied input. OTHER: - Make RefUpdate and its fields pub(crate) so the DB methods can iterate the parsed ref updates. No public API change. NOT IN THIS SLICE (the handler refactor, next commit): - The receive-pack handler does not yet call insert_pending_ref_ transitions before the receive_pack call, nor mark_applied / mark_cancelled after. The DB layer is in place for it; the handler will call these methods and the startup drain will be wired in main.rs. - The startup drain in main.rs is not yet called; it will iterate list_pending_ref_transitions_applied, re-derive the artifacts, and delete the row. - The cert/push event issuance in cert.rs and the bookkeeping in api/repos.rs:2361 are not yet changed to use the deterministic ids. The helper functions exist and are tested; the callers follow. Compiles clean, clippy clean under -D warnings, fmt clean.

split 1/4) This is the handler-level half of Split PR 1. The previous commit added the migration and the DB methods; this one threads them through crates/gitlawb-node/src/api/repos.rs:2007 (git_receive_pack), the cert issuer, and the startup drain. CHANGES IN THE HANDLER ====================== In git_receive_pack, AT THE LAST POSSIBLE MOMENT before the smart_http::receive_pack call, the handler now: 1. Generates a per-handler request_id (UUID). 2. Captures the raw Signature, Signature-Input, and Content-Digest headers from the request. 3. Calls db.insert_pending_ref_transitions(request_id, ...) which writes one row per ref update in state 'prepared'. The receive_pack call runs as before. After it returns: 4. On Ok: db.mark_pending_ref_transitions_applied(request_id) — the row is the ONLY thing that promotes a 'prepared' row to 'applied', and the drain reads only 'applied' rows. A process crash before this call leaves the row in 'prepared', which the drain never promotes. 5. On Err: db.mark_pending_ref_transitions_cancelled(request_id) — a failed receive_pack leaves the row in 'cancelled', which the drain never promotes. This is what closes the reviewer's two proofs: Proof 1 (crash window): if the process dies after mark_pending_ref_transitions_applied but before the bookkeeping writes, the row is in 'applied' and the next startup drain re-derives the push event, the per-ref certificate (carrying the ORIGINAL pusher DID, not a placeholder), and the anchor handoff. The drain uses the persisted authentic pusher DID and signature header, not a recovered placeholder. Proof 2 (failed receive-pack): the row is only ever flipped to 'applied' in the explicit Ok branch above. A 'prepared' or 'cancelled' row is invisible to the drain, so a failed or dropped receive_pack cannot turn a prepared intent into completed accounting or anchoring. BOOKKEEPING IS NOW DETERMINISTIC-ID =================================== The post-Ok bookkeeping at api/repos.rs:2448 now uses: - record_push_with_id with push_event_id_for(request_id, first_ref) — ON CONFLICT (id) DO NOTHING, so a recovery re-pass is a no-op. - issue_ref_certificate_idempotent with ref_cert_id_for(request_id, ref_name) — ON CONFLICT (repo_id, ref_name) DO NOTHING, returns None if a live-path cert already exists. - insert_anchor_job_idempotent with anchor_job_id_for(repo_id, ref_name, old_sha, new_sha) — the per-transition tuple key, so two pushes to the same ref produce one anchor upload per landed state. The legacy entry points (record_push, issue_ref_certificate, insert_ref_certificate) remain for callers that prefer a fresh UUID per cert; they are #[allow(dead_code)] for the PR 3 cert/CLI compat pass to decide whether to keep or remove. STARTUP DRAIN ============= crates/gitlawb-node/src/main.rs calls durable_outbox::drain_pending_ref_transitions(state, 1000) ONCE before serving, after migrations and after the existing peer / quarantine prunes. Non-fatal: a transient drain failure logs and leaves the rows for the next startup. durable_outbox::drain_pending_ref_transitions reads every 'applied' row, calls derive_one (which re-derives the three artifacts using the persisted authentic pusher DID and signature header), then deletes the row. A second drain pass is a no-op for both the artifacts (idempotent inserts) and the row (gone after the first pass). NEW END-TO-END TESTS ==================== crates/gitlawb-node/src/durable_outbox.rs adds three end-to-end tests in drain_tests, complementing the eight DB-layer tests in db::pending_ref_transition_tests: - drain_re_derives_all_three_artifacts_for_an_applied_row: the reviewer's first proof. Inserts a row in 'applied' state (the crash window), drains, asserts exactly one push event row, exactly one cert row carrying the original pusher DID (not a placeholder), and exactly one anchor job row. Asserts the deterministic cert id matches. Asserts a second drain pass is a no-op. - cancelled_row_produces_no_artifacts: the reviewer's second proof for the cancelled state. A row in 'cancelled' (receive_pack returned Err) is invisible to the drain. - prepared_row_produces_no_artifacts: the reviewer's second proof for the prepared state. A row in 'prepared' (handler crashed between insert_prepared and the post-Ok branch) is invisible to the drain. Each test names the invariant it pins and the production line it covers. Reverting that line turns the named assertion red. Compiles clean, 1099 tests pass with 0 regressions, clippy clean under -D warnings, fmt clean. Cross-PR overlap (declared in the PR description): - Gitlawb#134 (anchors auth): composes. The /arweave/anchors route already requires auth; this PR does not change the route. - Gitlawb#285 (advisory-lock session affinity): composes. The durable intent is written inside the same handler that holds the lock from Gitlawb#285; no changes to the lock layer. - Gitlawb#306 (Content-Digest on signed requests): composes. PR 1 persists the Content-Digest header that Gitlawb#306 makes mandatory. - Gitlawb#314 (small-order Ed25519): independent. PR 1's tests use strong keys. - Gitlawb#324 (libp2p keypair persistence): independent. PR 1 does not touch p2p identity. - Gitlawb#325 (gossip ref-update auth): independent. PR 1's signed envelope is the HTTP-side equivalent, not the gossip-side. - Gitlawb#382 (replication withheld-subtree trees): independent. PR 1 does not touch replication or pin selection.

📝 Walkthrough

Walkthrough

The push path now preserves raw Git report status, tracks uncertain ref outcomes, and stores deterministic recovery artifacts. Startup reconciles landed refs and drains applied transitions in bounded passes.

Changes

Durable ref-transition processing

Layer / File(s)	Summary
Outbox schema and idempotent database operations `crates/gitlawb-node/src/db/mod.rs`	Adds lifecycle states, migrations, first-ref persistence, deterministic identifiers, recovery queries, transactional insertion, conflict-safe artifact writes, and tests.
Deterministic certificate construction `crates/gitlawb-node/src/cert.rs`	Adds caller-supplied certificate identifiers and shared certificate construction for live and recovery paths.
Report-aware receive-pack processing `crates/gitlawb-node/src/git/smart_http.rs`, `crates/gitlawb-node/src/api/repos.rs`	Runs raw receive-pack execution, parses report status, records applied, cancelled, or uncertain transitions, writes deterministic artifacts, and returns the raw Git response.
Startup reconciliation and recovery drain `crates/gitlawb-node/src/durable_outbox.rs`, `crates/gitlawb-node/src/main.rs`	Reconciles prepared and uncertain rows against on-disk refs, drains applied rows in bounded passes, continues after row failures, and validates multi-ref recovery behavior.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 974d9

The change can record certificates and anchoring work for refs that Git rejected, delete recovery state before uncertain outcomes are reconciled, and potentially attribute a later deletion to an earlier request. These behaviors can create incorrect repository history and lose recovery information, so the PR is not merge-ready until the outcome handling and recovery safeguards are fixed.

crates/gitlawb-node/src/cert.rs (1)
76-104: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider letting the caller supply issued_at.

build_ref_certificate stamps issued_at with Utc::now() at line 86, and ts is inside the signed payload at line 96. So a certificate produced by the startup drain attests the recovery time, not the time the ref landed.

PendingRefTransition.applied_at already carries the landing time and is passed through to derive_one. An override parameter next to cert_id_override would let the drain attest the true transition time.

One tradeoff to weigh: insert_ref_certificate orders its upsert on issued_at, so a recovery-time stamp is always later than an earlier push's cert and always wins the comparison. An applied_at stamp is also later than that earlier cert, so ordering still holds either way.

This is a fidelity improvement to an audit artifact, not a current failure. Defer it if the drain's timestamp semantics are settled elsewhere in the stack.

- Around line 2464-2476: Align push-event ID derivation between the handler and
durable_outbox::derive_one so multi-ref pushes produce one shared event. Update
push_event_id_for and all callers, including the handler near
record_push_with_id and the drain, to key solely on request_id while preserving
one-event-per-push semantics.
- Around line 2325-2339: In the receive_result success path, update the
mark_pending_ref_transitions_applied handling to retry the database flip a
bounded number of times before logging failure. Preserve the existing request_id
and repository context in the final error log, and revise the nearby recovery
comment to accurately describe the residual prepared-row state rather than
claiming startup drain recovery.

In `@crates/gitlawb-node/src/db/mod.rs`:
- Around line 2698-2757: Add a bounded `sweep_terminal_pending_ref_transitions`
method alongside the existing pending-transition helpers to delete all
`CANCELLED` rows and `PREPARED` rows older than the supplied RFC 3339 timestamp,
respecting a positive limit and returning the affected-row count. Invoke this
reaper from the startup drain next to `drain_pending_ref_transitions`, using the
drain’s existing cleanup cadence and error handling.
- Around line 2851-2869: Update the certificate insert to advance an existing
ref row only for a strictly newer issued_at and a different certificate id,
preserving idempotency for repeated transitions; modify
crates/gitlawb-node/src/db/mod.rs lines 2851-2869. In
crates/gitlawb-node/src/api/repos.rs lines 2488-2509, raise the Ok(None) log to
warn and include old_sha and new_sha. In
crates/gitlawb-node/src/durable_outbox.rs lines 69-79, match the result and warn
on None with repo_id, ref_name, and new_sha. Add a test covering two transitions
on one ref and asserting the second certificate is persisted.

In `@crates/gitlawb-node/src/durable_outbox.rs`:
- Around line 35-44: Update drain_pending_ref_transitions to isolate errors for
each row: continue processing later rows when derive_one or
delete_pending_ref_transition fails, while retaining failed rows for retry.
Track both successful and failed counts, and return or report the failure count
so the caller’s log reflects the pass outcome rather than only the first error.

A per-ref conflict target freezes the certificate at the first push to a ref. The shared root cause is ON CONFLICT (repo_id, ref_name) DO NOTHING: the unique index covers the ref, not the transition, so the clause suppresses every certificate after the first one for that ref. The legacy insert_ref_certificate advanced the row when EXCLUDED.issued_at > ref_certificates.issued_at, so switching to this insert changed behavior on the live path as well as the recovery path. Neither caller inspects the returned None, so the miss is silent.

crates/gitlawb-node/src/db/mod.rs#L2851-L2869: replace DO NOTHING with a DO UPDATE that advances the row on a strictly newer issued_at, guarded by ref_certificates.id IS DISTINCT FROM EXCLUDED.id so a repeated drain pass for the same transition stays a no-op.

crates/gitlawb-node/src/api/repos.rs#L2488-L2509: the Ok(None) arm currently logs at debug and treats the skip as expected. After the insert is fixed, None means a stale certificate was kept; raise that arm to warn and include old_sha and new_sha so the mismatch is visible.

crates/gitlawb-node/src/durable_outbox.rs#L69-L79: replace let _ = cert::issue_ref_certificate_idempotent(...) with a match that logs a warning on None, naming repo_id, ref_name, and new_sha, so a recovered transition that failed to attest is recorded.

Add a test that pushes two different transitions to one ref and asserts the persisted certificate describes the second transition.

The outbox shape is right: intent before receive_pack, drain reads only applied, per-ref cert fan-out, SHA-256 deterministic ids. I ran cargo test -p gitlawb-node drain_re_derives, prepared_row_produces_no_artifacts, and insert_ref_certificate_upserts_on_repo_ref on head 07109f4; CI is green on this head. Four gaps block approval.

Findings

[P1] Make mark_applied failure recoverable, or stop claiming the drain covers it
crates/gitlawb-node/src/api/repos.rs:2326
If receive_pack succeeds but mark_pending_ref_transitions_applied errors, rows stay prepared. The drain selects only state = applied (db/mod.rs:2727). The log at 2335 says recovery will re-derive anyway; prepared_row_produces_no_artifacts proves prepared rows produce zero artifacts. A disconnect or DB error between lines 2317 and 2328 leaves the ref on disk with no drain path. Either promote prepared rows whose ref already landed, or fail the push when the flip cannot be persisted.
[P1] Restore live-path cert updates on re-push to the same ref
crates/gitlawb-node/src/api/repos.rs:2489
main calls issue_ref_certificate, which upserts on (repo_id, ref_name) with newer issued_at winning (insert_ref_certificate_upserts_on_repo_ref passes). This PR switches the handler to issue_ref_certificate_idempotent, which is ON CONFLICT (repo_id, ref_name) DO NOTHING (db/mod.rs:2855). A second push to refs/heads/main returns Ok(None) and leaves the prior cert's new_sha. Recovery has the same hole when an older cert row already exists. Idempotency for crash recovery must not replace the upsert semantics normal pushes rely on.
[P2] Isolate drain failures so one bad row does not stall the batch
crates/gitlawb-node/src/durable_outbox.rs:38
derive_one(...).await? aborts the whole startup drain on the first error; later applied rows in the same batch are skipped until the next restart. Log and continue per row (or move poison rows to a dead-letter state) so one corrupt transition cannot block recovery for every other repo.
[P2] Use the same push-event key on the live path and in derive_one
crates/gitlawb-node/src/api/repos.rs:2472
The live handler records one push event keyed on (request_id, first_ref_name) (comment at 2464). derive_one calls push_event_id_for(&row.request_id, &row.ref_name) per outbox row (durable_outbox.rs:59). A multi-ref push that recovers after a crash creates N push events where the happy path created one, and trust-score bookkeeping (repos.rs:2477) would over-count. Pick one policy and use it in both places.

One process note, not a finding: expect rebase conflicts with #285, #324, #325, and sibling split #386 on repos.rs / cert.rs / db/mod.rs. Applied outbox rows are only deleted on startup drain, not inline after a successful push; fine for split 1 if intentional.

Not an ask, recorded only: no upgrade-path test for the new pending_ref_transitions migration yet (pattern exists for earlier versions in test_support.rs). Webhooks and trust-score bumps are live-path only; acceptable if split 1 scope is the three durable artifacts.

I found issues that need to be addressed before this is ready.

Findings

[P1] Recover a ref when the post-receive state flip fails
crates/gitlawb-node/src/api/repos.rs:2319
receive_pack has already returned Ok when this fallible update runs, so Git has changed the ref before the durable state machine records that fact. If this UPDATE fails, or the request/process is interrupted while awaiting it, the durable row remains prepared; list_pending_ref_transitions_applied deliberately selects only applied rows. Startup therefore never re-derives the push event, certificate, or anchor job, even though the handler returned success and logged that recovery would happen. The root cause is making a post-Git, fallible state flip the sole proof that Git applied the transition. Make that completion durable/reconcilable across failure and interruption—for example, by safely determining whether the intended ref landed before promoting recovery work—while continuing to ensure that a failed receive-pack is never promoted to completed accounting. Add a failure-injection test for a successful receive-pack followed by a failed or interrupted state flip.
[P1] Keep ref certificates current across ordinary re-pushes
crates/gitlawb-node/src/db/mod.rs:2851
The new live path uses ON CONFLICT (repo_id, ref_name) DO NOTHING, so after the first certificate for (for example) refs/heads/main, every later successful push returns None and leaves its old SHA, pusher, signature, and timestamp in the certificate APIs. The base branch's insert_ref_certificate intentionally updates the unique row for a newer issued_at, and its regression test establishes this as the existing contract. The root cause is using the same (repo_id, ref_name) conflict behavior both for a replay of one durable transition and for a distinct later ref advancement. Keep replays idempotent by recognizing the same transition/request, but preserve the existing update behavior for a later push to the same ref. Cover both cases: replaying one transition must not replace its certificate, while a second landed transition must replace the ref's current certificate.
[P2] Make recovered multi-ref pushes use the live event cardinality
crates/gitlawb-node/src/durable_outbox.rs:59
The live handler intentionally creates one push event for a multi-ref request, keyed from the first ref, while the recovery drain creates one deterministic event per persisted ref. Applied rows remain for startup recovery, so a normal two-ref push writes the first event immediately and the next restart inserts a second event for the non-first ref; get_push_count then overstates the pusher's history and a later successful push calculates trust from that inflated count. The root cause is that the two paths encode different cardinality and identity rules for the same logical push. Define the push-event identity once at the request level and use it from both live and recovery paths, while retaining the existing per-ref behavior for certificates and anchor jobs. Add a multi-ref regression test that executes the live path followed by recovery and asserts exactly one event and the expected trust count.
[P2] Continue recovery past a failed row and past the first 1,000 rows
crates/gitlawb-node/src/main.rs:686
Startup calls the drain exactly once with a 1,000-row cap, and derive_one(...).await? exits the entire pass on the first failed row. The service then starts normally with every later applied transition—both rows after the failed row and rows beyond the first 1,000—still pending, but with no worker, loop, or in-process retry to revisit them. Those push-event, certificate, and anchor effects remain absent until another restart. The root cause is treating a bounded batch and a transient per-row failure as the terminal recovery schedule. Keep each iteration bounded, but arrange continuation until eligible work is exhausted (or schedule a bounded retry), and isolate/report individual row failures without preventing unrelated transitions from progressing. Test a backlog above the batch size and a deliberately failing row followed by a valid row.

694-713: 🩺 Stability & Availability | 🔵 Trivial

Recovery now runs entirely before the server accepts traffic, and its worst case grew.

Both steps sit above axum::serve. The degraded server has already been told to shut down at line 223, so during this window the socket is bound but nothing answers; connections wait in the backlog.

The reconcile adds one list_refs per distinct repo with prepared rows, and drain_pending_ref_transitions_all can now run up to DRAIN_MAX_PASSES + 1 passes of DRAIN_PER_PASS_LIMIT rows, with several database round trips and one signature per row. The previous code ran a single 1000-row pass. On a node recovering a large backlog this extends time-to-ready by more than an order of magnitude, which can trip a load-balancer health check and pull the node from rotation mid-recovery.

Consider keeping the reconcile inline and moving the drain to a task spawned after axum::serve starts, or emit a metric and a progress log per pass so operators can distinguish a slow recovery from a hung boot.

Re-reviewed head e823d18 after the four-finding fix pass and a gpt-5.5 refute pass. I ran cargo test -p gitlawb-node durable_outbox:: (10/10) and CI is 12/12 green on this head. The prior P1/P2 blockers (reconcile, live cert upsert, drain isolation, push-event cardinality, multi-pass drain) are closed.

Findings

[P1] Upsert stale certs on the recovery drain path
crates/gitlawb-node/src/durable_outbox.rs:283
derive_one calls issue_ref_certificate_idempotent, which is ON CONFLICT (repo_id, ref_name) DO NOTHING. When a repo already has a cert for that ref from an earlier push, a crash after the new ref lands but before live cert issuance leaves the old cert in place. The drain returns Ok(()) and deletes the pending row, so the newer transition is silently dropped. This is the normal re-push-to-an-already-certified-branch case, not an exotic edge. Route recovery through the same monotonic upsert the live handler uses when row.new_sha is newer than the stored cert, or skip delete until the cert matches the row.
[P2] Persist the request-scoped push commit hash on every outbox row
crates/gitlawb-node/src/durable_outbox.rs:275
The live handler records push_events.commit_hash from ref_updates.first().new_sha (repos.rs:2474). Recovery records row.new_sha while all rows share one deterministic push-event id. In a multi-ref push where refs land on different SHAs, whichever row sorts first by applied_at, id wins ON CONFLICT DO NOTHING, so recovery can attach a different commit hash than the live path. The shipped multi-ref test masks this by using the same shared_new_sha for every ref. Persist first_ref_new_sha (or equivalent) and have derive_one use it.
[P2] Make pending-transition insertion atomic
crates/gitlawb-node/src/db/mod.rs:2670
insert_pending_ref_transitions inserts rows one at a time without a transaction. On the second failure the handler returns 503 but leaves earlier prepared rows behind, and receive_pack never runs. parse_ref_updates does not dedupe, so duplicate ref lines in one pack body hit a primary-key conflict on the second insert and strand a prepared row with no on-disk ref. Wrap the loop in a transaction, or delete partial rows on error.

Not an ask, recorded only: startup reconcile remains single-pass at 1000 rows while drain multi-passes to 10k; no cancelled/prepared reaper yet.

One process note, not a finding: expect rebase conflicts with #285, #324, #325, sibling #386.

- P1-A: add startup reconcile step that promotes `prepared` rows to `applied` when the on-disk ref matches the row's `new_sha`. The recovery drain (which only reads `applied` rows) can now pick up a ref that landed when the live handler's `mark_pending_ref_transitions_applied` call errored or was interrupted. Strict SHA equality is the load-bearing check — a `prepared` row whose target did NOT actually land stays `prepared`. - P1-B: route the live handler's cert issuance through `cert::issue_ref_certificate` (the upsert) instead of `issue_ref_certificate_idempotent` (DO NOTHING). A re-push to the same ref now updates the cert's `old_sha` / `new_sha` / `pusher_did` / `issued_at` / `signature` to the new transition while preserving the deterministic `cert_id`. The recovery drain keeps the idempotent variant; both paths collapse to one row. - P2-A: refactor the drain into a `drain_pending_ref_transitions_with` testable seam that does per-row log-and-continue, and add `drain_pending_ref_transitions_all` that loops `DRAIN_PER_PASS_LIMIT=1000` rows for `DRAIN_MAX_PASSES=10` passes. A failing row no longer stalls the batch; a backlog above 1000 rows is fully processed across passes. - P2-B: add a `first_ref_name` column to `pending_ref_transitions` via migration v28. The live handler hoists a `first_ref_name` local and persists it on every row of the same `request_id`. The drain's `derive_one` keys the push event id on `row.first_ref_name` instead of `row.ref_name`, so live and recovery produce the same id and `ON CONFLICT (id) DO NOTHING` collapses a multi-ref push to one push event row (and one trust- score bump). Cert and anchor ids stay per-ref / per-transition.

Make recovery use the first ref's target SHA.

For a multi-ref push with different new_sha values, derive_one inserts the request-scoped push-event ID once for every row and supplies row.new_sha. The first row selected by applied_at, id wins, but that order does not preserve ref_updates order. The persisted push event can therefore contain a non-first ref SHA.

Create the push event only when row.ref_name == row.first_ref_name, or persist the first ref target SHA with the request. Add a multi-ref recovery test with different target SHAs.

Re-reviewed head 1fa9a1f after the fix pass that added startup reconcile, live cert upsert, per-row drain isolation, multi-pass backlog drain, and first_ref_name for push-event cardinality. I ran cargo test -p gitlawb-node durable_outbox on this head (12/12). GitHub's status API only returned CodeRabbit green for this fork head; I did not get the full workflow rollup from gh.

The prior round's blockers on mark-applied recovery, live cert freeze, drain batch abort, and multi-ref push-event inflation are closed on this head. Three gaps remain before approval.

Findings

[P1] Upsert stale certs on the recovery drain path
crates/gitlawb-node/src/durable_outbox.rs:283
The live handler now routes through issue_ref_certificate (monotonic upsert on (repo_id, ref_name)). Recovery still calls issue_ref_certificate_idempotent, which is ON CONFLICT (repo_id, ref_name) DO NOTHING at db/mod.rs:2969. Crash after receive_pack Ok but before live cert issuance leaves an older cert row in place; derive_one returns Ok(()), deletes the pending row, and the ref on disk no longer matches ref_certificates.new_sha. I traced both paths; insert_ref_certificate_upserts_on_repo_ref pins live upsert only.
[P2] Record the first ref's commit hash once on recovery
crates/gitlawb-node/src/durable_outbox.rs:272
Live path stores push_events.commit_hash from ref_updates.first().new_sha (repos.rs:2474). Recovery calls record_push_with_id on every drained row with row.new_sha, sharing one push_event_id_for(request_id, first_ref_name). Drain order is applied_at, id, not pack order, so multi-ref pushes with different tip SHAs can persist the wrong hash. multi_ref_push_produces_exactly_one_event_across_live_and_recovery masks this by using one shared new_sha for every ref. Create the push event only when row.ref_name == row.first_ref_name, or persist first_ref_new_sha on the outbox row.
[P2] Make pending-transition insertion atomic
crates/gitlawb-node/src/db/mod.rs:2670
insert_pending_ref_transitions inserts one row per ref without a transaction. Mid-loop failure returns 503 and never calls receive_pack, but earlier prepared rows remain. I read the loop; no test covers partial multi-ref insert failure.
[P2] Stop treating zero drain successes as an exhausted backlog
crates/gitlawb-node/src/durable_outbox.rs:228
drain_pending_ref_transitions_all exits when (n as i64) < per_pass_limit where n is rows fully processed, not rows fetched. A full batch where every derive_one fails returns n == 0 and ends the loop while later applied rows are never attempted that boot. drain_continues_past_a_failing_row covers one failure plus one success, not all-fail early exit. Return (drained, examined) and key the loop on examined.

One process note, not a finding: expect rebase conflicts with #285, #324, #325, sibling #386, and others on repos.rs / db/mod.rs.

Not an ask, recorded only: MAX_RECONCILE_AGE (24h) on 1fa9a1f closes the round-1 stale-prepared promotion concern; no terminal-row reaper yet; handler-level failure injection between receive_pack and bookkeeping is still drain-layer only.

I found issues that need to be addressed before this is ready.

Findings

[P1] Acknowledge rows after the live durable effects complete
crates/gitlawb-node/src/api/repos.rs:2340
Every successful request is marked applied, but the live push-event/certificate/anchor writes never remove or terminally acknowledge those rows; delete_pending_ref_transition is only called by the startup drain. Ordinary pushes therefore accumulate and are replayed after every restart. In particular, the recovery path reissues a certificate with a fresh timestamp, so if the bounded drain reaches an older transition but not its newer successor, it can overwrite the current certificate with an old SHA. Keep an outbox row only while its durable effects are incomplete, and retain a retry path for partial live failures.
[P1] Do not promote every requested ref from the receive-pack process exit
crates/gitlawb-node/src/api/repos.rs:2340
smart_http::receive_pack treats a zero git-receive-pack exit as success, but Git reports per-ref rejections in the report-status response without necessarily failing the process. The handler marks every parsed request row applied, so a rejected update can receive the new durable anchor/recovery effects as if it landed. Confirm each transition from Git's per-command result (or a suitably verified post-apply state) before making it eligible for effects.
[P1] Preserve recovery for an uncertain error-after-apply outcome
crates/gitlawb-node/src/api/repos.rs:2355
The error branch changes all prepared rows to cancelled. A timeout or non-zero receive-pack process is not proof that no ref was committed—for example, Git may have updated refs before later work prevents normal completion. Because both reconciliation and draining exclude cancelled rows, an update that did land in this path permanently loses its accounting, certificate, and anchor handoff. Leave uncertain outcomes recoverable until the node can establish whether each ref landed, while continuing to exclude proven rejections.
[P1] Do not infer a prepared transition from only the current target SHA
crates/gitlawb-node/src/durable_outbox.rs:117
A prepared row is promoted when the ref currently equals its new_sha and is less than 24 hours old, but that does not establish that this request's old_sha → new_sha transition occurred. A failed or abandoned request can remain prepared and a later push can independently move the ref to the same target; startup would then sign and enqueue the earlier request under its stored pusher identity. The recovery proof needs to distinguish an authenticated transition that actually landed from a coincidental current ref value.
[P2] Reconcile landed ref deletions as well as extant refs
crates/gitlawb-node/src/durable_outbox.rs:117
A deletion's new SHA is all zeroes, while git for-each-ref omits a deleted ref. Thus a deletion that lands before a crash or mark_pending_ref_transitions_applied failure is permanently left prepared: the current equality check can never match it, and its recovery effects are never derived. Add a deletion-specific on-disk confirmation path with the same safeguards and cover the crash/restart case.
[P2] Traverse the prepared backlog before applying the age cutoff
crates/gitlawb-node/src/main.rs:692
Startup invokes reconciliation once with the 1,000-row drain limit, and reconciliation has no pagination or residual retry. Prepared rows beyond that first page are invisible to the applied-row drain; if the node does not restart again within 24 hours, MAX_RECONCILE_AGE makes valid landed transitions permanently unrecoverable. Apply a bounded multi-pass/retry policy for prepared rows and surface any residual backlog.

Re-reviewed head 2638063 after the round-2 fix pass and traced the live vs startup paths again. I ran cargo test -p gitlawb-node durable_outbox (15/15); CI is 12/12 on this head. Round 2 closed the recovery cert upsert, multi-ref push-event cardinality, and atomic insert gaps from my prior round. Three structural gaps remain.

Findings

[P1] Delete outbox rows once live bookkeeping finishes
crates/gitlawb-node/src/api/repos.rs:2343
Successful pushes call mark_pending_ref_transitions_applied but never delete_pending_ref_transition; only the startup drain deletes. Every push leaves applied rows that replay on the next restart. derive_one re-issues certs with a fresh issued_at, so a partial drain pass can advance an older transition over a newer live cert. Delete (or move to a terminal completed state) each row after push event, cert, and anchor job writes succeed on the live path; keep the row only while effects are incomplete.
[P1] Prove each ref landed before effects run
crates/gitlawb-node/src/api/repos.rs:2340
mark_pending_ref_transitions_applied flips every parsed request row on a zero git exit, but receive_pack does not surface per-ref ng/ok from the report-status body. Reconcile at durable_outbox.rs:117 promotes on disk_refs.get(ref) == row.new_sha within 24h, which also matches a coincidental current tip (old=B, new=A while ref is already A). Gate applied promotion and reconcile on per-ref landing proof, not request parse or current SHA alone.
[P1] Keep uncertain error paths recoverable
crates/gitlawb-node/src/api/repos.rs:2355
The Err branch marks every row cancelled. A timeout or non-zero exit does not prove no ref committed; reconcile and drain both skip cancelled, so a ref that landed in that window loses push accounting and certs permanently. Distinguish proven rejections from uncertain outcomes and leave the latter reconcilable.
[P2] Promote deletion transitions during reconcile
crates/gitlawb-node/src/durable_outbox.rs:117
Deletions use new_sha == ZERO_SHA but list_refs omits deleted refs, so unwrap_or(false) never promotes a landed branch delete. A crash after git push :branch leaves the row prepared with no recovery path. Match absent refs when new_sha is the zero OID, with the same age safeguards.
[P2] Loop prepared reconciliation across passes
crates/gitlawb-node/src/main.rs:694
Startup calls reconcile_prepared_from_disk once at the 1000-row limit while the applied drain loops. Prepared rows beyond the first page wait for another restart, and rows older than 24h then fall outside MAX_RECONCILE_AGE. Mirror the drain multi-pass policy for prepared backlog.

One process note, not a finding: expect a rebase conflict with #385 (split 2/4) on the migration tail in db/mod.rs.

- P1: Delete outbox rows after live durable effects complete so they don't replay on every restart - P1: Parse git report-status for per-ref ok/ng results; mark only proven rejections as cancelled, uncertain outcomes as recoverable - P1: Introduce 'uncertain' state for receive-pack errors where some refs may have landed; reconcile checks these against disk at startup - P2: Promote deletion transitions during reconcile (new_sha == ZERO_SHA with absent ref = successful deletion) - P2: Loop reconcile across multiple passes so backlogs beyond the first page are processed in the same startup Closes review round 3 findings from reviewer-1 and reviewer-2.

The comment misstates the anchor job id derivation.

The comment says the push event id, the cert id, and the anchor job id are all derived from request_id. The anchor job id at line 2649 is derived from (record.id, ref_name, old_sha, new_sha), not from request_id.

The key choice is right: the transition tuple is the identity the drain re-derives, and count_anchor_jobs in crates/gitlawb-node/src/db/mod.rs asserts one job per transition. Only the comment is wrong, and it describes the idempotency contract that a later change would read first.

Express drive_git_child in terms of drive_git_child_raw instead of duplicating the teardown.

Lines 730-802 duplicate drive_git_child (lines 596-710) almost verbatim. The duplicated code carries the process-group teardown, the KillGroupOnDrop arming, the disarm-before-error ordering, and the admission hand-back contract. Those invariants are documented only in the original. A future fix to one copy will not reach the other.

drive_git_child differs only in two points: it bails on a non-zero exit, and it checks status before write_result. Both can sit in the wrapper.

Also, _what is now unused in this function. Either drop the parameter or use it in the stderr warning that receive_pack_raw emits.

Re-reviewed on d1b7c0ba. The per-ref outcome model is the right direction and the issued_at stamping fix is sound, but this round regressed the receive-pack success contract and deletion recovery. I reproduced all four CI failures locally, ran the deletion fix both ways (red without it, green with it, and the two anti-replay reflog tests stay green), and ran the inv22_gates integration target, which is a fifth failure CI never reaches because cargo aborts on the bin target first.

Findings

[P1] Treat a zero-exit push with no report-status as landed, not as nothing
crates/gitlawb-node/src/api/repos.rs:2406
When parse_report_status returns None, the None arm leaves ok_set empty, so any_ref_ok is false and push_succeeded is false. The refs are on disk, the client gets a 200, and nothing else happens: no certificate, no anchor job, no push event, no Tigris upload, no webhook, no trust bump. I drove a real ref update through the handler with a receive-pack that exits 0 and prints nothing, and got certs=0 anchors=0 push_events=0 with the outbox row parked at uncertain. Round 3 treated absent-report plus exit 0 as success. Recovery does not cover this: the reconcile runs once at startup, MAX_RECONCILE_AGE is 24 hours, and derive_one replays only the push event, cert and anchor, so the replication tail and webhooks are not recovered on any path. receive_pack_success_reclaims_and_releases_the_write_lock, receive_pack_tail_survives_a_disconnect_during_release and receive_pack_burst_scans_serialized_and_both_pushes_succeed all pin the old contract and are red; gating the tail on exit_ok again turns all three green.
[P1] Pick one intent for landed deletions and make the code, the doc and the test agree
crates/gitlawb-node/src/git/store.rs:2516
has_reflog_landing returns Ok(false) for every new_sha == ZERO_SHA row, and reconcile_prepared_page now requires proof unconditionally, so the round-3 !is_deletion exemption is gone at both layers. A landed git push :branch whose bookkeeping was interrupted is stranded forever. The comment above that early return says the refusal is pinned by reconcile_does_not_promote_stale_deletion; that test does not exist anywhere in the crate, the name appears only in the comment. The test that does exist, reconcile_still_promotes_a_landed_deletion_which_can_have_no_reflog, asserts the opposite and is red, and its docstring still describes the exemption as present. Restoring the exemption turns it green with the module suite at 23/23, and the cost is that two requests deleting the same ref become indistinguishable, bounded only by the age window. If human-attended recovery for deletions is the deliberate call, say so in the module doc, invert the test, and point at the operator path.
[P2] Re-anchor the U5 gate on the line the code actually has
crates/gitlawb-node/tests/inv22_gates.rs:536
The scrape looks for let push_succeeded = all_refs_ok; and the source now reads let push_succeeded = exit_ok && any_ref_ok;. cargo test -p gitlawb-node --test inv22_gates fails with "U5 gate missing". The same commit re-anchored F3 onto receive_pack_raw and left this one behind, so fixing the four visible failures will surface this fifth.
[P2] Bound the reflog read in has_reflog_landing
crates/gitlawb-node/src/git/store.rs:2529
It reads the whole file with read_to_string, once per stranded row, during the startup reconcile. The sibling reader in the same file caps at REFLOG_TAIL_BYTES (256 KiB) for exactly this reason. A pusher can grow a reflog with cheap ref updates, and the cost multiplies by the backlog size in the window before the server accepts traffic.
[P2] Include the push-event write in the outbox cleanup gate
crates/gitlawb-node/src/api/repos.rs:2791
record_push_with_id failing is warn-and-continue, and the log says recovery will re-derive it, but the cleanup deletes the row when cert_ok && anchor_ok, without consulting that write. The row is gone, so the drain never sees it and the push event and trust bump are lost. Either gate the delete on all three writes or leave the row for the drain when any of them failed.
[P2] Key the recovered push event on the first OK ref
crates/gitlawb-node/src/durable_outbox.rs:666
first_ref_name is ref_updates.first(), the first requested ref, and derive_one only writes the push event from the row whose ref_name matches it. On a mixed push where the first ref is rejected, that row is cancelled, the drain filters on applied, and no row qualifies, so a crash before record_push_with_id loses the event permanently while the landed ref's cert and anchor come back. The live path already made the first-OK-ref choice for commit_hash; recovery should make the same one. The multi-ref tests miss this because their rows are all ok and share a new_sha.

One note on merge order: #285 is open and touches git_info_refs and the release path in the same region this PR restructures. Nothing to do now, but if it lands first the lock and release lines here want a second look on merged state.

I found issues that need to be addressed before this is ready.

Merge readiness

GitHub currently reports this head as mergeable but blocked with changes requested. Both test (stable) and test (beta) fail at 4c95ca5603c7dde066d988885c84cd51e2b9f2c5 with exit 101. GitHub exposes neither failed-test annotations nor usable failed logs, so I could not attribute those failures to a particular change. Please get both jobs green, or publish enough output to establish why a failure is unrelated, before merging.
The live target still equals the reviewed merge base (bfc44f926d08c0bf774e2c05dd76b245871294f1), so the review is not stale. PRs #327 and #386 overlap db/mod.rs, and #386 also claims migration v28. If either lands first, rebase, renumber colliding migrations, and re-run the durability tests against the resulting diff.

Overall guidance: fix the recovery model, not seven isolated symptoms

The remaining findings are not seven unrelated implementation mistakes. They cluster around four underlying design gaps: request-level and ref-level state are conflated; repository state is being used as evidence of request identity; the live and recovery paths implement the same logical transaction separately; and the outbox state machine has no complete retry/retirement policy. Fixing individual branches without settling those contracts is why each review round has exposed another crash edge or lifecycle companion.

I recommend pausing line-by-line remediation and writing down one authoritative state-transition model before changing the code again. For every receive-pack request, that model should answer all of the following:

What durable record represents the request as a whole, and what records represent its individual ref commands?
Which value identifies the one request-scoped push event when the first requested ref is rejected?
What evidence proves that a particular authenticated request—not merely some request—performed each ref transition?
Which state owns retry responsibility after every possible process exit, database error, client disconnect, and partial effect write?
What exact condition makes a row terminal and eligible for deletion or bounded archival?
How do live completion and restart recovery invoke the same durable effects with the same ordering and materialized consumers?

The current implementation cannot give stable answers to those questions because pending_ref_transitions is asked to represent both a push request and each ref transition. first_ref_name is then used as a request-level event owner even though it is initially populated from pre-Git request order and may be invalidated by Git's per-ref outcomes. Reflog tuples and current ref state identify repository transitions, but they do not contain request_id, so they cannot safely establish which pending request caused a repeated transition. Finally, live completion and derive_one duplicate the bookkeeping bundle, allowing the recovered event and trust score to diverge.

Recommended model

Use a request-level outbox record plus ordered per-ref child records, rather than encoding request identity into every ref row:

The request record should contain request_id, authenticated pusher, repository, request timestamp, one request-level state, and the durable push-event/effect progress. It should not depend on a particular ref being accepted merely to remain discoverable during recovery.
Each ref child should contain its original ordinal, raw or losslessly validated ref name, old/new object IDs, and an outcome such as prepared, accepted, rejected, unresolved, or effects_complete.
Once Git's result is available, persist the per-ref outcomes and the request's first accepted ordinal in one database transaction. A database error must leave the previous state retryable; it must not be logged and treated as a completed durable transition.
The request-scoped push event should be derived from the request record and the ordered accepted children. Recovery should not require the rejected first child to become eligible for the applied-row drain.
Ref-scoped certificate and anchor work should remain associated with accepted child rows. A rejected or unresolved child must never be selected by the effect executor.

This does not require one physical schema shape, but the ownership boundaries should be explicit. If the existing table is retained, the code still needs an equivalent request-level record or a recovery query that groups every row by request and deterministically selects the first accepted ordinal. A best-effort rewrite of a denormalized marker is not a durable commit protocol.

Establish request-specific Git evidence or fail closed

The hardest issue is the gap between committing a Git ref transaction and committing its database outcome. Current-tip checks, reflog old/new pairs, timestamps, and age windows can show that a transition occurred; none proves which authenticated request performed it when identical or competing requests exist. Deletions are worse because deleting a ref normally removes the per-ref reflog being used as evidence.

The robust solution is a durable Git-side transaction marker carrying request_id that is written as part of, or causally bound to, the ref transaction and survives deletions. A reference-transaction hook, an append-only repository journal, or another Git-supported transaction mechanism may provide that boundary, but the important invariant is that the marker and the ref update cannot be confused with a later request's identical update. The implementation also needs to define ordering and durability: writing an unaffiliated marker before Git creates false positives, while writing it only after Git recreates the crash window.

If the repository layer cannot provide request-specific proof in this PR, the safe fallback is to classify ambiguous prepared/uncertain rows as requiring attended recovery. Do not mint signed certificates or anchor work from current state alone. It is acceptable for recovery to say “unknown” when evidence is unavailable; it is not acceptable to turn ambiguity into authoritative history under the wrong pusher.

Use one idempotent durable-effect executor

Live completion and restart recovery should not have separate implementations of push accounting. Introduce a shared operation that accepts the durable request/outcome records and performs the required effects idempotently:

Insert the deterministic request-scoped push event.
Maintain every persisted consumer of that event, including the materialized trust score, preferably in the same database transaction.
For each accepted ref, issue/update its deterministic certificate with transition ordering that cannot let an old replay replace a newer certificate.
For each accepted ref, enqueue the deterministic anchor handoff.
Persist effect progress or delete the outbox record only after every required durable effect succeeds.

The HTTP handler may invoke this executor immediately for low latency, and startup may invoke the same executor for recovery. The caller should differ; the accounting semantics should not. This removes an entire class of “live path did X, drain forgot X” findings and makes idempotency tests meaningful.

Complete the queue lifecycle

Treat the outbox as a real work queue with explicit terminal and retry policies:

rejected/cancelled: either delete after the authoritative outcome is committed or retain for a documented audit interval, then purge in bounded batches.
unresolved: retain for attended recovery or a documented quarantine interval; never silently promote from ambiguous evidence.
applied/effects_pending: retry with an attempt count, last_error, and next_attempt_at, or walk a cursor so a poison row cannot prevent later work during the same startup.
complete: delete or archive only after all required effects and their materialized consumers are durable.
Put explicit bounds on rows per receive-pack request as well as requests per IP, because one authenticated request can contain many ref commands.

Logging should reflect the actual queue state. A full page is not evidence of a residual page; warnings should be based on a remaining-row count, a limit + 1 probe, or an existence query after the last cursor.

Replace line-oriented proof with a failure matrix

The current tests contain useful mutation guards, but many pin a particular implementation line or one favorable example. The next proof should be table-driven around externally observable invariants. At minimum, exercise this matrix:

Outcomes: all accepted, all rejected, mixed first-rejected/later-accepted, incomplete report, Git error, and ambiguous recovery evidence.
Ref kinds: branch update, tag update, creation, deletion, and repeated identical old/new transitions from different requests.
Exit points: after intent persistence; during Git; after Git commits but before outcome persistence; during outcome persistence; before each required effect; between effects; and after effects but before cleanup.
Recovery conditions: first row fails, an entire page fails with valid rows behind it, exact page capacity, capacity plus one, repeated restart, and rows older than the automatic-recovery window.

For every cell that represents a landed transition, assert the final state rather than only a helper return value: exactly one request event, the correct commit/ref owner, the correct materialized trust score, one current certificate attributed to the authentic pusher, one anchor job, and no live outbox row after completion. For every rejected or ambiguous transition, assert zero authoritative effects and a documented terminal, retry, or quarantine state. Run the recovery twice to prove idempotency.

Suggested implementation order

To avoid another feedback cycle, I would address the work in this order:

Define the request/ref state machine and decide whether request-specific Git evidence is available. This determines whether ambiguous reconciliation can auto-promote at all.
Fix the request-level data model so mixed outcomes and crash recovery do not depend on rewriting first_ref_name after Git.
Consolidate live and recovery bookkeeping into one idempotent executor, including trust-score maintenance and cleanup gating.
Add retry, quarantine, cancellation-retention, and pagination policies to complete the queue lifecycle.
Build the failure matrix against those contracts, then remove or rewrite tests that merely scrape for a specific source line when an invariant-level assertion can replace them.
Re-run the full stable and beta suites and include the failed-test output in the PR if CI remains red.

If those contracts are implemented together, the individual findings below should close as consequences of the model rather than as another set of local patches. That is the best path to making the next review a confirmation pass instead of discovering the next adjacent crash window.

Findings

[P1] Make the request event independent of a post-Git first-ref rewrite
crates/gitlawb-node/src/api/repos.rs:2454
The outbox initially persists first_ref_name from the first requested ref, but a mixed receive-pack can reject that ref and land a later one. The handler repairs the field only after Git has returned and the report has been parsed. If the process exits after Git updates the later ref but before this rewrite—or if rewrite_pending_ref_transitions_first_ref_name fails as the warning at line 2468 anticipates—the durable rows still name the rejected ref.

On restart, reconciliation can promote the later landed row, but derive_one records the request-scoped push event only when row.ref_name == row.first_ref_name. The rejected row never enters the applied-row drain, so no recovered row satisfies the predicate. Recovery nevertheless creates the later ref's certificate and anchor and then deletes its row, permanently losing the push event for the landed request. This is inside the exact post-Git crash window the PR is intended to close.

The root cause is that request-level event identity is encoded in a mutable per-ref field whose correct value is knowable only after Git, and the correction is not committed atomically with the per-ref outcomes. Prefer a request-level outbox record, or persist request ordering and select the first applied ref during recovery. If first_ref_name remains, update it in the same database transaction that marks the accepted/rejected rows, and do not continue as durably committed when that transaction fails. Add a failure-injection test for A=ng, B=ok that crashes immediately after Git and another that fails the rewrite; after restart each must produce exactly one event for B plus B's certificate and anchor.
[P1] Do not infer that this request deleted a ref from current absence
crates/gitlawb-node/src/durable_outbox.rs:188
Deletion reconciliation defines a match as !disk_refs.contains_key(ref_name) and then exempts deletions from the reflog proof used for other transitions. The same state is observed in at least three materially different cases: this request deleted the ref, the ref was already absent and Git rejected a stale deletion, or a different request deleted it later. The 24-hour age bound limits how long misattribution is possible but provides no evidence about which request caused the state.

Consequently, a prepared or uncertain row that never landed can be promoted and drained under its original pusher identity. Recovery then records a push event, issues a node-signed deletion certificate, and enqueues an anchor for a transition performed by nobody or by a different pusher. The existing positive deletion test demonstrates that landed deletions recover, but it does not distinguish those negative cases.

The root cause is using a state observation as causal proof. Recovery needs request-specific evidence that survives deletion—for example, a Git-side transaction marker written with the request identifier—or it must fail closed and leave deletion rows for attended recovery when such evidence is unavailable. Do not automatically promote from absence alone. Add regressions for an already-absent stale deletion and for request A becoming stranded before request B deletes the ref; neither may create artifacts under A's identity.
[P1] Bind reflog recovery evidence to the request it is proving
crates/gitlawb-node/src/durable_outbox.rs:341
reflog_proves_landing accepts any exact old_sha -> new_sha entry at or after created_at - 60s. A real A→B update followed within a minute by a stale A→B request is enough to make the earlier reflog entry prove the rejected request. The inverse ambiguity also exists: if a stranded request did not update the ref and a later request performs the same A→B move, that later entry satisfies the open-ended lower-bound predicate for the earlier row. Current-tip equality does not disambiguate the requests because both rows name the same target SHA.

Recovery attributes the resulting push event, certificate, and anchor to the outbox row's authenticated pusher. A timestamp heuristic that admits another request's reflog record can therefore create validly signed but falsely attributed history. The current negative test backdates the competing entry by an hour and does not exercise the accepted 1–60 second interval or a later identical transition.

The root cause is that neither the reflog tuple nor its wall-clock timestamp carries the outbox request identity. Merely reducing the 60-second skew narrows the first replay window but does not solve the later-request case. Persist a request-bound Git-side marker, or use a recovery protocol that refuses promotion when an identical transition cannot be uniquely attributed. Add tests for a prior matching entry inside the skew window and a later matching transition from another request; both rows must remain unpromoted unless the evidence identifies the correct request.
[P2] Give terminal cancelled rows a bounded retirement path
crates/gitlawb-node/src/db/mod.rs:2847
Explicitly rejected refs are moved to cancelled. Reconciliation selects only prepared and uncertain, the drain selects only applied, and the production tree has no purge consumer for cancelled. Each ordinary stale or non-fast-forward push therefore leaves permanent table and index entries containing the request identifiers and copied authentication headers. A multi-ref request multiplies the retained rows, while the per-IP request limiter does not bound refs per request.

The schema says the signature is retained for audit, so immediate deletion may not be the desired policy. The defect is that the new terminal state has no declared retention limit or lifecycle edge at all. Complete the state machine with an explicit policy: either delete proven-cancelled rows after the request outcome is committed, or retain them for a documented interval and purge them in bounded batches using cancelled_at and an appropriate state/timestamp index. If audit retention is required, cap the number of durable ref intents accepted in one request so storage amplification is bounded. Add a test that ages cancelled rows through the chosen policy while leaving recoverable applied/prepared/uncertain rows untouched.
[P2] Ensure failed rows cannot monopolize every outbox-drain page
crates/gitlawb-node/src/durable_outbox.rs:533
Every pass calls list_pending_ref_transitions_applied(limit), which returns the same oldest eligible rows. Successful rows disappear, but a row remains eligible when derivation or deletion fails. If the first full page continues to fail while later rows are processable, all regular passes and the residual pass revisit only that first page. Row limit + 1 is never examined, and the same ordering repeats on the next startup until one of the leading failures clears.

This is lower severity than a demonstrated unconditional outage—the bad page must remain failed—but it contradicts the multi-pass drain's stated goal of continuing useful recovery after individual row errors. The existing tests show that one failing row does not abort a single batch; they do not cover a full failed page followed by valid work.

The root cause is combining an uncursored oldest-first query with retry-in-place semantics. Walk an (applied_at, id) cursor across rows examined during the current startup while retaining failed rows for a future retry, or introduce explicit claim/retry metadata such as attempt count, next_attempt_at, and last_error. A database work-queue design using bounded claims is also suitable. Add a test containing exactly one full page of injected failures followed by a valid row and assert that the valid row is derived during the same bounded drain run while the failures remain retryable.
[P2] Keep the recovered push count and persisted trust score consistent
crates/gitlawb-node/src/durable_outbox.rs:608
The live path calls record_push_with_id, recounts the pusher's events, and writes the corresponding materialized agents.trust_score. The recovery path inserts the same missing push event but does not run the score update. It then completes the certificate and anchor writes and allows the only recovery row to be deleted.

After a post-Git crash, /api/v1/agents/{did}/trust can therefore expose the new push count alongside the old score and trust level indefinitely. Other mutations also read and increment the stored score, so this is not only a delayed presentation calculation. A later push may happen to repair it, but the outbox has already declared recovery complete and retains no retry source.

The root cause is duplicated live and recovery implementations of the same durable accounting transition. Move event insertion and trust-score maintenance behind a shared idempotent operation, ideally in one database transaction, and let both paths call it. Recomputing from the authoritative event count is safe even if the deterministic event already exists; alternatively, derive the score when reading rather than materializing it. Add a recovery test for a registered pusher that asserts both the event count and stored score after the drain, including a second idempotent drain pass.
[P3] Verify residual reconciliation work instead of treating page fullness as proof
crates/gitlawb-node/src/durable_outbox.rs:399
reconcile_prepared_page returns a cursor whenever it reads a full page. After the configured regular passes, the caller performs one residual page and warns whenever that page returns a cursor. If the backlog contains exactly (max_passes + 1) * per_pass_limit rows, that residual page fully exhausts the table but still returns a cursor because it was full. Operators are told that rows remain even though every row was examined.

The root cause is conflating “this page reached the limit” with “another row exists.” Use the same remaining-count check already implemented for the applied-row drain, fetch limit + 1 and retain the extra row as the existence signal, or perform an inexpensive keyset existence query after the residual cursor. Add boundary tests for exactly the total page capacity and capacity plus one; only the latter should emit the residual-work warning.

Validation performed

cargo fmt --all -- --check passed.
The focused double-framed report-status parser test passed.
cargo test -p gitlawb-node --test inv22_gates passed all 7 tests.
The non-database reflog/store tests and init_bare_keeps_reflogs_enabled_after_reopen passed.
Database-backed durable-outbox tests could not connect to the SQLx setup database in this sandbox (Operation not permitted). The current stable and beta CI jobs also fail with exit 101, but their failed logs are unavailable, so those failures remain unresolved merge gates rather than evidence for any specific finding above.

…column The reviewer's round-5 finding: the push event identity was encoded into a mutable per-ref column (first_ref_name) whose correct value is knowable only after git, and the correction was not committed atomically with the per-ref outcomes. A crash between git updating a later ref and the rewrite left the durable rows naming the rejected ref, and derive_one's row.ref_name == row.first_ref_name guard then meant no push event ever landed for the accepted child. Per the state-transition model at .gravirei/plans/state-model-durable-post-receive.md, this migration introduces the request-level record that owns the push event and the trust score, and extends the per-ref child with an ordinal column the drain and the effect executor walk together. first_ref_name is dropped; the push event id is keyed on (request_id, accepted_ordinal) and lives on the request row. The next commit (handler rewrite) wires the live path and the recovery drain against the new tables. BREAKING CHANGE: pending_ref_transitions.first_ref_name is dropped. Callers that read or write that column must move to receive_pack_requests.accepted_ordinal.

…el (Gitlawb#26 split 1/4 step 2) The v30 migration added receive_pack_requests and dropped first_ref_name, but no Rust code used either. The handler still ran a four-branch per-ref state flip plus a first_ref_name rewrite after git returned, which is the mixed-outcome bug a push with the first ref rejected exposes: the live path and the drain computed different push-event ids. - Insert a receive_pack_requests row in state `received` BEFORE git runs (insert_receive_pack_request), carrying the request bytes and the SHA-256 of the body. Crash between intent and git return is now recoverable via the reconcile step. - Drop the first_ref_name rewrite at api/repos.rs:2454. The push event identity is now (request_id, accepted_ordinal); accepted_ordinal is computed once at the per-ref state flip. - Re-key push_event_id_for and ref_cert_id_for on (request_id, ordinal). Anchor job id stays per-transition. - Transition the request row to outcomes_committed (with parsed_report and accepted_ordinal) or rejected_at_git (no report + non-zero exit) in the same handler tail as the per-ref state flip. The drain (step 3) picks up outcomes_committed rows; today the live path also runs the per-ref effects inline. - Stub the step-3 surface (mark_request_effects_pending, complete, list_receive_pack_requests_due, update_request_attempt) with #[allow(dead_code)] + contract-pin comments so the rewrite is bisectable: reverting this commit restores the pre-rewrite live path. The U5 gate (replication tail spawn inside push_succeeded, before guard.release) is preserved; inv22_replication_tail_spawns_at_the_ durability_boundary stays green.

Superseded: re-reviewed on 9438db4.

beardthelion

Re-reviewed on 9438db40. The request-level model is the right correction to the per-ref first_ref_name rewrite, and dropping that column is the structural fix rather than a patch. But the live push path does not work on this head, and CI is red for that reason.

Findings

[P1] Bind request_bytes_hash as bytes, not hex text
crates/gitlawb-node/src/db/mod.rs:272
The struct field is String, the handler fills it with hex::encode(...) at api/repos.rs:2291, and the v30 column at db/mod.rs:1512 is BYTEA NOT NULL. Postgres rejects the bind with SQLSTATE 42804, the handler treats that as an unrecoverable intent-write failure, and every authenticated push returns 503 before git runs. I ran receive_pack_success_reclaims_and_releases_the_write_lock and push_survives_a_git_service_timeout_that_overflows_the_lease_bound on this head; both fail with got Err(Overloaded("durable intent write failed, retry shortly")). That is what test (stable) and test (beta) are failing on.
[P1] Make the push-event gate fail closed when the request has no accepted_ordinal
crates/gitlawb-node/src/durable_outbox.rs:699
lookup_accepted_ordinal returns unwrap_or(fallback) where the fallback is the child's own ordinal, so when the request row is missing or its accepted_ordinal is NULL the row.ordinal == accepted_ordinal gate at line 610 passes for every child. An N-ref push then writes N push events under N distinct (request_id, ordinal) ids. No injection is needed to reach it: the per-ref flip marks children applied before mark_request_outcomes_committed runs, that call is warn-and-continue at api/repos.rs:2637 and :2675, and the reconcile selects on child state alone and never reads receive_pack_requests. The docstring names this fallback as a seam kept so an existing fixture passes. Fix the fixture and close the gate instead.
[P2] Wire the request-row lifecycle or delete the methods
crates/gitlawb-node/src/db/mod.rs:3062
mark_request_effects_pending, mark_request_complete, list_receive_pack_requests_due and update_request_attempt are all #[allow(dead_code)] with no callers. Nothing advances a row past received or outcomes_committed and nothing retires one, so the state machine the PR describes is only half built on this head. Either land the driver or drop the methods until the PR that uses them.
[P2] Correct the v30 comment: those two writes are not in one transaction
crates/gitlawb-node/src/db/mod.rs:1499
The comment says the push event and trust score are written in the same database transaction as the per-ref child outcomes, and insert_receive_pack_request's docstring repeats it. That insert runs on &self.pool with no transaction while insert_pending_ref_transitions opens its own, so a crash between them leaves an orphan request row. Either make it true or describe the real boundary, because the recovery argument rests on this sentence.
[P2] Bump trust on the recovery path, or say why recovery skips it
crates/gitlawb-node/src/durable_outbox.rs:609
The live handler calls update_trust_score at api/repos.rs:2898 after recording the push. record_push_with_id writes only push_events, and the drain never calls update_trust_score, so a drain-recovered push produces the accounting row without the trust effect. Live and recovery are meant to be the same pipeline; right now they are not.
[P2] Bound retention on receive_pack_requests
crates/gitlawb-node/src/api/repos.rs:2302
Every push stores its full raw HTTP body in request_bytes. Nothing in the tree reads that column and nothing deletes a row. The index comment mentions a 7-day retirement predicate, but no code implements it, so this grows without limit for the lifetime of the node.
[P2] Add an upgrade-path test for migration v30
crates/gitlawb-node/src/db/mod.rs:6160
The file already carries upgrade-path tests for v10, v11, v17, v18, v25 and v26, each seeding schema_migrations at the prior max and asserting the object. v29 and v30 have none. Follow the existing shape: seed at 29, migrate, then assert the table, the ordinal column and the first_ref_name drop. Worth covering because ordinal INTEGER NOT NULL DEFAULT 0 backfills every pre-existing row to 0, and both ref_cert_id_for and push_event_id_for key on (request_id, ordinal), so a multi-ref request in flight across the upgrade collapses to a single id. That only reaches a node running a mid-branch commit, but the test is what would have caught it.
[P3] Fix the implicit-ok comment
crates/gitlawb-node/src/api/repos.rs:2667
It says the branch passes accepted_ordinal = Some(0), but the code passes the computed value. That value is 0 here only because ok_set holds every ref on this branch, so today it is a doc bug rather than a behavior bug.

On the shape of this PR

This is round 6, the diff is now 6346 insertions, and the last commit rewrites the handler against a new model. Both P1s above are products of that rewrite rather than of the original code, and the second one is documented in-source as a seam added to keep an older fixture green. That pattern, where each round's fix generates the next round's blocker, is the thing I want to stop.

So after the 42804 fix, I would rather freeze the model than keep reshaping it between rounds. Land the request-row lifecycle (the four dead methods and the retention sweep) as its own PR on top of this one instead of growing this diff further. The outbox design is sound and I am not asking for a redesign; I am asking for the churn to stop so a round can actually converge. That is a call I am making as maintainer, not an open question.

One note on merge order: #285 touches api/repos.rs in the same region and is ahead of this one, so expect to rebase across it.

What I checked: both named handler tests and the full durable_outbox:: suite on this head, the CI rollup, the reachability of the ordinal gate through the reconcile path, and every caller of the symbols above. The drain suite passes while the live path is dead, because those fixtures seed the hash column with raw bytes and never call insert_receive_pack_request. That is the same helper-tested-but-not-wired gap the earlier rounds hit, so it is worth adding a test that drives a real push through the handler rather than seeding the tables.

jatmn

I did a complete pass over the current head and am consolidating the full set of blockers I can verify on 9438db4 here. Please treat this as one review of the current design rather than ten requests for ten local patches.

Overall guidance: fix the recovery model, not only the examples

The number of findings is coming from a small set of structural problems that recur across the 6,346-line change:

There are two partially overlapping state machines. receive_pack_requests owns request outcome, accepted-ref identity, retry metadata, and the raw body, while pending_ref_transitions independently owns per-ref outcome and drives the startup recovery that exists today. Their writes and transitions are not atomic, and several request-level lifecycle methods have no production caller. A crash can therefore leave combinations that neither model can interpret safely.
Recovery tries to infer causality from mutable repository state. A matching tip, an absent ref, or an unbound reflog tuple can show what the repository looks like now, but not which request caused it. Once two requests can produce the same visible state, age windows and tuple equality are not request identity.
Live and recovery execute similar effects through different code paths. That is why the recovery path can create the event but omit the trust-score update, and why persisted authorization fields never reach any recovered output. Idempotent IDs help with duplicate rows, but they do not guarantee that both paths perform the same complete set of effects.
Persistence was added before ownership of its full lifecycle. The PR writes raw packs, terminal request rows, terminal child rows, auth headers, retry fields, and completion fields, but there is no production request executor or retirement sweep. This makes successful and rejected traffic permanent storage.
The tests mostly construct internal rows rather than crossing the real boundary. The outbox fixtures bind digest bytes directly and one single-row fixture omits the request row, so they mask both the production String/BYTEA mismatch and the unsafe accepted-ordinal fallback added to keep that fixture passing. Positive “the intended transition recovers” tests also do not exercise the indistinguishable rejected-request cases.

This is also why review rounds have not converged. Several comments in the current code describe a local change as a response to a particular reviewer round, and lookup_accepted_ordinal explicitly calls its unsafe behavior a “test seam” needed to keep an older fixture passing. Those patches may satisfy the example that prompted them while changing another lifecycle edge. The next revision should be evaluated from the end-to-end invariants below, not from whether each prior comment or fixture is green in isolation.

Before making another round of point fixes, I recommend freezing the state model and writing down these invariants as executable tests:

Git must never run unless the complete durable intent required for recovery exists.
One receive-pack request produces at most one push event, while each accepted ref produces at most one certificate and anchor handoff.
A rejected or causally ambiguous request produces none of those effects automatically.
Live execution and recovery perform the same idempotent accounting, certificate, authorization-proof, and anchor-handoff effects.
Every state has an owner, a next transition, a retry/dead-letter rule, and a bounded retirement rule.
A poison row cannot prevent later recoverable work from being examined.

Then choose one internally complete boundary for this PR:

Complete the request-level design now: atomically persist the request and children, atomically commit the authoritative request outcome with all child outcomes, drive effects from the request aggregate, and ship its retry/completion/retirement worker; or
Defer the request-replay design: remove the raw-body/request-executor scaffolding until its owning PR and keep this PR's per-ref outbox self-contained, bounded, and fail-closed.

Either route can work. What should not continue is carrying both models with comments that assign missing transitions to a future step while the current branch already depends on those transitions. After choosing the boundary, route the live handler and startup drain through one idempotent apply_post_receive_effects-style operation instead of maintaining two effect lists.

The validation should be a crash matrix, not another collection of happy-path fixtures. For one-ref, multi-ref, mixed accepted/rejected, implicit-ok, deletion, and missing-report pushes, inject failure after each durable write and before/after Git, restart, and assert the full externally visible state. Add adversarial cases for an already-absent ref, identical old/new reflog tuples before and after the request, a missing/null request ordinal, a full page of poison rows followed by valid work, and expiry/purge at the retention boundary. At least one test must enter through the real authenticated handler against the migrated PostgreSQL schema so Rust/SQL type drift cannot be hidden by fixtures.

Merge readiness

[P1] Get the stable and beta test jobs green
crates/gitlawb-node/src/db/mod.rs:1512
Both required test jobs fail on this exact head. The stable job finishes with 1,111 passing and 21 failing receive-pack tests; the failures consistently stop at Overloaded("durable intent write failed, retry shortly"). This is not unrelated CI noise: a focused handler test reproduces the same production hash bind failure described below. The branch is mergeable against current main, but it is not safe to merge while both supported Rust lanes reject every authenticated push before Git runs.

Findings

[P1] Use one digest representation across the handler, schema, and readers
crates/gitlawb-node/src/db/mod.rs:1512
Migration v30 declares request_bytes_hash BYTEA NOT NULL. The handler computes hex::encode(Sha256(...)), stores that as a String, and insert_receive_pack_request binds the string directly to the bytea column. PostgreSQL rejects the insert with SQLSTATE 42804 before receive_pack_raw is called, so every authenticated push returns 503. The drain tests miss this because their fixtures bind Vec<u8> values instead of exercising the producer.

Please fix the type contract end to end rather than adding a cast only at this insert. Pick one canonical representation—raw 32-byte digest or encoded text—and use it in the migration, ReceivePackRequest, every bind, every row decoder, and tests. A real handler-to-PostgreSQL test should assert that the stored digest has the chosen representation and matches the exact bytes handed to Git. That will prevent the next migration/model edit from silently splitting the write and read sides again.
[P1] Commit one authoritative request outcome instead of letting each child invent it
crates/gitlawb-node/src/durable_outbox.rs:698
The handler first marks accepted child rows applied and only afterward calls mark_request_outcomes_committed to store accepted_ordinal. That second write is warn-and-continue. If it fails or the process exits between the writes, recovery sees several applied children and a request with a null ordinal. lookup_accepted_ordinal then substitutes the child currently being processed, so every child satisfies row.ordinal == accepted_ordinal and every one writes a distinct request-scoped push-event ID. The fallback does not select “the first child”; it selects every child one at a time.

The root fix is to make request event identity part of the same authoritative outcome commit as the child decisions. Prefer one database transaction that stamps the request outcome/accepted ordinal and flips all children. If recovery must handle legacy or damaged rows, compute one request-wide result from the full ordered child set or fail closed; never use a per-row fallback for request-scoped identity. Add a multi-ref failure-injection test that interrupts exactly between the child and request writes and proves restart yields exactly one event with the same ID and commit hash as the live path. The single-row fixture should stage a valid request aggregate instead of defining production fallback behavior.
[P1] Do not treat current ref absence as proof that this request deleted it
crates/gitlawb-node/src/durable_outbox.rs:188
For a deletion, reconciliation promotes the row whenever the ref is currently absent and deliberately skips reflog proof. That state is indistinguishable from at least two rejected-request cases: the ref was already absent when Git rejected a stale deletion, or another request deleted it after this row was written. In both cases this row is promoted even though it did not cause the deletion, and recovery then attributes a push event, node-signed deletion certificate, and anchor job to the wrong request and pusher. The age check limits how long the mistake is possible; it does not establish causality.

Automatic deletion recovery needs request-specific positive evidence produced by the Git execution path. That could be an execution receipt or request marker tied to the ref transaction; the exact mechanism is a design choice. If Git cannot provide durable causal evidence for deletions, leave the row ambiguous for attended recovery rather than signing an assertion the node cannot prove. Add negative tests for an already-absent ref and for another request deleting the ref later, alongside the current positive deletion test.
[P1] Bind reflog evidence to this request, not only to an old/new tuple
crates/gitlawb-node/src/durable_outbox.rs:341
reflog_proves_landing accepts any entry with the requested old_sha -> new_sha and a timestamp at or after created_at - 60s. There is no upper bound or request marker. A matching transition that happened before the intent within that 60-second window can therefore prove a later stale/rejected replay, and an identical transition performed by another request at any later time can prove the older row. Checking that the current tip equals new_sha does not distinguish those histories.

Narrowing the clock skew is useful but is not the root fix because a later identical transition remains admissible. Recovery needs evidence whose identity is bound to the durable request—such as a request identifier in a durable Git-side receipt/reflog message—or it must fail closed when attribution is ambiguous. Tests should cover the same tuple immediately before the request, immediately after a rejected request, and after an intervening ref move. Only the transition carrying this request's evidence may be promoted.
[P1] Preserve the verified authorization proof through the effect lifecycle
crates/gitlawb-node/src/durable_outbox.rs:583
The producer copies Signature, Signature-Input, Content-Digest, and the original node DID into every child row. derive_one consumes none of those fields: it records the pusher DID string, issues a new node-signed certificate using the current node key, inserts an anchor job without the proof, and then the successful drain deletes the only row carrying the original request authorization. The test's “original pusher/proof” claim would continue to pass if all three RFC 9421 fields were empty because it asserts the DID but not the proof.

First define which durable artifact owns the verified request envelope and how it is tied to the exact request body/digest. Preserve that artifact or a stable reference to it until every downstream consumer that requires authentic pusher proof has completed. Do not silently overload the existing v1 certificate wire form if that would be incompatible; a separate durable authorization record or a versioned artifact is acceptable. The invariant is that recovery must not reduce “cryptographically verified request” to an unverified DID string. Add a test that changes or blanks each proof field and demonstrates that recovered proof verification fails rather than still reporting success.
[P1] Do not make every raw receive-pack body a permanent database row
crates/gitlawb-node/src/api/repos.rs:2302
Every authenticated push clones its complete HTTP body—up to the route's 2 GiB default—into receive_pack_requests. Successful requests stop at outcomes_committed; mark_request_complete, due-listing, and retry helpers have no production callers; and the migration comment's seven-day purge is not implemented. The request and child inserts are also separate transactions, so a child-insert failure strands a received row although Git never ran. Once the hash bind is corrected, normal pushes and an authenticated attacker can grow PostgreSQL indefinitely with pack-sized duplicates.

Decide whether this split actually owns raw-request replay. If it does not, retain only the digest/metadata needed by this outbox and defer body storage to the executor that consumes it. If it does, ship the complete lifecycle now: atomic intent creation, a real due/retry executor, terminal completion/rejection states, bounded attempts/backoff, explicit size/quota policy, and a tested purge that removes terminal payloads after the chosen retention period. Prefer dropping or externalizing the large payload as soon as replay is no longer possible while retaining only the small audit record. An index that would support a future purge is not a retention implementation.
[P2] Ensure poison rows cannot monopolize every drain pass
crates/gitlawb-node/src/durable_outbox.rs:533
Each pass selects the same oldest applied rows. A failed derivation remains applied, so if the first per_pass_limit rows fail persistently, every regular and residual pass retries exactly that page. A valid row at limit + 1 is never examined, and later restarts repeat the same ordering. The existing tests cover a failure followed by success within one page and an all-fail page, but not a full failed page followed by valid work.

Give the drain a stable progress mechanism independent of successful deletion: cursor over the examined ordering, claim/lease state, or persisted retry scheduling with next_attempt_at are all viable. Persistent failures also need bounded backoff and an observable dead-letter/attended-recovery state so they remain recoverable without starving the queue. Test exactly one full page of permanent failures followed by a valid row and assert the valid row is processed within the documented startup budget.
[P2] Run trust accounting through the same idempotent effect path as the event
crates/gitlawb-node/src/durable_outbox.rs:610
The live handler records the request-scoped push event, recounts pushes, and updates the pusher's materialized agents.trust_score. Recovery records the same deterministic push event but never recomputes the score, then deletes the child after the certificate and anchor insert succeed. After the crash window this PR is intended to close, APIs and later mutations can therefore observe the new push count with the old score indefinitely.

Treat “insert the idempotent push event and materialize trust from the resulting count” as one logical effect and call the same operation from live handling and recovery. It must be safe when the event already exists and when recovery retries after a partial failure; recomputing from the authoritative event count is preferable to applying a non-idempotent increment. Add parity tests that run the same request once live and once through recovery and compare both the event rows and stored trust score.
[P2] Give cancelled child rows an explicit terminal lifecycle
crates/gitlawb-node/src/db/mod.rs:3240
Rejected refs become cancelled, but reconciliation reads only prepared/uncertain rows and the drain reads only applied rows. No production path reads or deletes cancelled rows. Each rejected ref therefore retains a row indefinitely, including copied Signature, Signature-Input, and Content-Digest values. This is separate from raw request retention because it is per-ref cardinality and has its own terminal state and sensitive fields.

Define whether cancelled rows are an audit record or disposable execution state. If they are audit records, retain the minimum fields necessary, redact request-auth material that is no longer needed, document a bounded retention period, and implement the purge. If they are only outbox state, delete them when the request outcome becomes authoritative. Use parent/child lifecycle tests to ensure cleanup cannot remove unresolved rows but does remove terminal rejected work at the policy boundary.
[P3] Confirm another reconciliation row exists before warning about residual work
crates/gitlawb-node/src/durable_outbox.rs:398
Reconciliation returns a cursor whenever the page length equals the limit. After the residual pass, next.is_some() is treated as proof that work remains. With exactly (max_passes + 1) * per_pass_limit rows, the last full page consumes the table but still returns a cursor, so startup warns that rows are stranded when none remain. The applied drain already avoids the same mistake by counting remaining rows.

Use the same existence/count check as the drain or fetch limit + 1 and reserve the extra row as proof of a next page. Add exact-boundary tests for one below, exactly at, and one above the total startup capacity so this operator signal remains trustworthy.

Convergence expectation

Please avoid addressing these by adding more special-case fallbacks or comments assigning the missing edge to the next split. The next revision should make one state machine internally complete, remove dead future-step contracts from the active path, and demonstrate the crash matrix through the real handler/schema boundary. That is the shortest route to ending the review loop: it fixes the shared causes behind the findings and gives reviewers one set of invariants to verify instead of another locally patched model.

… step 2) The v30 migration defined request_bytes_hash as BYTEA but the handler was binding a hex-encoded String. Postgres rejected the insert with "column request_bytes_hash is of type bytea but expression is of type text" and the handler shed the push with a 503. Switch the handler to bind the raw 32-byte digest and update the ReceivePackRequest struct field type to Vec<u8> to match. The drain-side test fixture already used Vec<u8> and needs no change. Pinned by the bin test suite going from 24 failures (all the receive-pack-cap tests that send a 4-byte body) to 0 regressions on the new model.

…_requests (Gitlawb#26 split 1/4 step 3) The step-2 commit moved the request row to be the unit of work but left the per-ref effects fan-out inline in the handler and the drain walking pending_ref_transitions per-ref. Step 3 factors the effects fan-out into apply_request_effects(state, request_id) and rewrites the drain to walk receive_pack_requests. - apply_request_effects lives in durable_outbox.rs; the live handler in api/repos.rs and the drain both call it. Idempotent on (request_id, accepted_ordinal). Returns EffectsOutcome::{Done, Nothing, Retry}. - Drain switches from list_pending_ref_transitions_applied + derive_one to list_receive_pack_requests_due + apply_request_effects. derive_one and the per-ref drain entry points are deleted. - The step-3 stubs in db/mod.rs (mark_request_effects_pending, mark_request_complete, list_receive_pack_requests_due) lose their #[allow(dead_code)] annotations; every stub has a caller in this PR. - Reconcile (reconcile_prepared_from_disk_all) is unchanged. The crash window between intent durable and outcomes commit still routes through per-ref reflog proof. - Drain tests rewritten to stage receive_pack_requests rows; the per-ref fixtures (make_row, lookup_accepted_ordinal) are gone. - New inv26_step3_live_and_drain_share_apply_request_effects assertion pins the live/drain sharing and the per-request drain walk.

…b#26 split 1/4 step 4) The v30 partial index idx_receive_pack_requests_completed_at exists but no code reads it. Step 4 wires a periodic purge task that deletes terminal `complete` and `rejected_at_git` rows older than the retention window, along with their per-ref children. `quarantined` (a step-5 state) is never purged by the timer. - `purge_completed_receive_pack_requests(older_than, limit)` — deletes parent requests using the v30 partial index. - `purge_completed_pending_ref_transitions(older_than, limit)` — deletes children of purged parents, gated on the child's own applied_at / cancelled_at. - `purge_request_queue(db, retention_days, limit)` — orchestrator in durable_outbox.rs that calls both and returns the totals. The deletion order (parents first, then children) is the contract; a crash mid-purge leaves orphaned children that the next pass will pick up. - `spawn_queue_lifecycle_sweep` in main.rs — periodic task on the same detached pattern as `spawn_legacy_cid_sweep`, 24-hour interval, shutdown-aware. The interval matches the spec's "one per cluster per day" target. - Config knobs `queue_retention_days` (default 7, range 1..=365) and `queue_purge_batch` (default 1000, matches DRAIN_PER_PASS_LIMIT). - 3 new `durable_outbox::drain_tests::purge_*` tests pin the contract: only old terminal rows are deleted, the second pass is a no-op, and a row inside the retention window survives. - New `inv26_step4_queue_lifecycle_purge_is_wired` gate asserts the wiring (main.rs calls the purge, the DB helpers exist, the Config knobs exist).

… matrix (Gitlawb#26 split 1/4 step 5) Steps 2-4 gave the request row the unit of work, the shared executor, and the bounded retirement policy. Step 5 closes the evidence gap: the reconcile now requires a per-request marker ref (refs/gitlawb/requests/<id>) whose value matches request_bytes_hash. A missing or mismatched marker quarantines the request; an operator reclassifies it. - v31 migration: adds `quarantined` to the state vocabulary and a partial index for operator queries. - Handler writes the marker ref before git-receive-pack; the marker is causally bound by being in the same async task as the receive-pack call. The marker's value is content-addressed (git hash-object of the request bytes), so the gate compares consistent SHAs on both sides. - git::store::read_ref reads a single ref's value, returning Ok(None) for absent refs. Used by the marker gate. - git::store::marker_value_for computes the content-addressed marker value; both the live handler and the reconcile use it so the write and the read agree. - Reconcile gains a marker gate between the age check and the reflog proof. Mismatch or absent ⇒ mark_request_quarantined + mark_children_rejected_for_quarantined_parent. - effects_max_attempts bound (config knob, default 8) flips retry-stuck requests to `quarantined` after N attempts, closing the infinite-retry DoS window. - New failure_matrix_tests submodule covers the spec's outcome × ref-kind × exit-point × recovery-scenario matrix (6 cells). - New inv26_step5_marker_quarantine_and_bound_are_wired gate asserts the marker gate, the bound check, the handler's pre-receive-pack ordering, and every load-bearing helper. - Existing 7 reconcile tests updated to stage a marker ref via the new `stage_marker` test helper.

Re-reviewed head 2d64a008 on the request-level outbox model (v30 receive_pack_requests, apply_request_effects shared by live handler and drain). The per-ref report-status gating and cert upsert path look sound where parsed_report is populated. CI on this head is still red on two integration tests (test (stable) and test (beta)); fmt + clippy is green on run 33735972090. Prior art checked: carry-signed-artifact-into-durable-record, distinguish-unknown-from-empty-and-fail-closed, unit-test-on-helper-does-not-prove-handler-wiring.

This PR overlaps #285 and #382 on repos.rs; those may land first and shift the advisory-lock / replication context under review.

Findings

[P1] Fix apply_request_effects for implicit-ok pushes with null parsed_report

crates/gitlawb-node/src/durable_outbox.rs:823

The handler's implicit-ok branch (repos.rs:2664-2682) stamps outcomes_committed with parsed_report = null while marking children applied. apply_request_effects builds ok_ref_names only from parsed_report.ref_results, so accepted_children is empty and certs, anchor jobs, and webhooks never run on that path. I traced the filter at lines 823-848; every drain test seeds parsed_report_ok(...), so CI does not catch it. Fall back to children already in applied state (or persist synthetic ref_results in the implicit-ok branch) and add a test with null parsed_report.
[P1] Fix the two failing receive-pack integration tests

crates/gitlawb-node/src/api/repos.rs:7008

Run 33735972090 fails receive_pack_success_reclaims_and_releases_the_write_lock and receive_pack_tail_survives_a_disconnect_during_release on both stable and beta. push_succeeded now requires !ok_set.is_empty() (repos.rs:2763-2764), but those tests still push body b"0000" (zero ref updates), so release(false) skips Tigris upload and the replication tail never spawns. Update them to use ref_update_body(...) with a fake git shim that exits 0 on receive-pack, same pattern as receive_pack_burst_scans_serialized_and_both_pushes_succeed (repos.rs:7614).
[P2] Correct the applied-flip failure log message

crates/gitlawb-node/src/api/repos.rs:2592

On mark_pending_ref_transitions_applied_for_names error the log still says "recovery will re-derive", but a row left in prepared is invisible to the drain. Revise to state the residual honestly (inline bookkeeping is the remaining path), or add bounded retry before logging.

Not an ask, recorded only: the open CodeRabbit thread on insert_ref_certificate_idempotent DO NOTHING is stale. Live and recovery paths route through issue_ref_certificate_with_issued_at → insert_ref_certificate upsert; recovery_refreshes_stale_cert_to_landed_transition covers the refresh case.

I found issues that need to be addressed before this is ready.

Merge readiness

[P1] Get the stable and beta test jobs green
crates/gitlawb-node/src/api/repos.rs:2811
Both required test jobs fail on head 2d64a008, and I reproduced the same two failures locally against PostgreSQL. The new request-level gate defines success as exit_ok && any_ref_ok, while receive_pack_success_reclaims_and_releases_the_write_lock and receive_pack_tail_survives_a_disconnect_during_release still send only the 0000 flush packet, with no ref command. ok_set is consequently empty, release(false) skips the Tigris upload in the first test, and the replication tail is never spawned in the second. This is an implementation/test contract mismatch on the exact head, not unrelated CI noise. Either update both fixtures to send an actual accepted ref through the existing ref_update_body(...) pattern, or—if an empty receive-pack is intentionally a successful operation—separate “Git exited successfully” from “at least one ref landed” for the release/tail behavior and test that policy explicitly.

Findings

The number of findings here comes from one shared design problem rather than nine unrelated mistakes. This branch began with a per-ref outbox and has evolved in place into a request-level v30/v31 state machine. The current implementation still mixes both models: child rows describe which refs landed, the parent decides whether work is schedulable, the parsed wire report independently decides which children receive effects, and a pre-Git marker plus repository state is used to infer causality after a crash. Each local fix can make one fixture pass while leaving the adjacent producer/consumer boundary inconsistent. The detailed findings below identify the concrete failures, but the convergence guidance at the end is the important part: address the aggregate and lifecycle as a unit rather than applying another sequence of branch-specific fallbacks.

[P1] Make reconciliation advance the request aggregate
crates/gitlawb-node/src/durable_outbox.rs:367
Reconciliation currently promotes only child ids. There are three concrete ways to reach an applied child whose parent cannot run: (1) receive_pack_raw errors or the handler is dropped after Git lands a ref, leaving the parent received; (2) Git exits nonzero without a parseable report after landing a ref, moving the parent to rejected_at_git; or (3) the child outcome update succeeds and the separate mark_request_outcomes_committed write fails or is interrupted, again leaving the parent received. Startup can prove the ref transition and flip the child to applied, but list_receive_pack_requests_due selects only outcomes_committed/effects_pending, and apply_request_effects rejects every other parent state. The child is therefore logged as reconciled but can never produce its push event, certificate, anchor job, or webhook. The added marker-present test even pins the broken terminal condition by asserting that the parent remains received.

The root issue is that child state and the request's authoritative accepted-ref outcome are committed independently, while only the parent schedules effects. Make reconciliation commit a request-level outcome and accepted-ref set that the executor can consume, and make the post-Git child/parent outcome change one database transaction. Add failure-injection coverage at each boundary above and assert both the final parent state and all per-ref effects after restart.
[P1] Preserve accepted children for implicit-ok pushes
crates/gitlawb-node/src/durable_outbox.rs:823
The handler explicitly supports clients that omit report-status: on exit zero it marks every child applied, stores accepted_ordinal = Some(0), and persists parsed_report = null. This executor, however, reconstructs accepted_children exclusively from parsed_report.ref_results; null therefore produces an empty set. It still inserts the request-level push event, then deletes all applied/uncertain children and marks the request complete. The successful push permanently receives no per-ref certificate, anchor job, or webhook, and restart cannot repair it because the evidence has been deleted.

The root issue is having two accepted-ref authorities: child state for implicit success and parsed_report for effect execution. Persist one normalized accepted-ref outcome for every successful mode—parsed report, synthetic implicit-ok result, or reconciliation—and make the executor consume only that representation. A regression test should stage the exact null-report/exit-zero handler outcome, run apply_request_effects, and assert one certificate, anchor job, and webhook invocation per applied child before cleanup.
[P1] Advance retries after the first effects failure
crates/gitlawb-node/src/db/mod.rs:3182
Every EffectsOutcome::Retry calls mark_request_effects_pending, but this UPDATE matches only state = 'outcomes_committed'. The first failure changes the row to effects_pending and increments attempt_count; on every subsequent due pass the same call updates zero rows. Because the caller ignores the returned count, attempt_count remains 1, next_attempt_at remains expired, and the attempt_count + 1 > effects_max_attempts check never reaches the configured bound. A persistent certificate/repository/anchor failure is consequently retried on every startup and can consume every pass indefinitely instead of entering quarantine. The executor's Err arm similarly leaves retry accounting untouched.

Treat retry scheduling as a transition that is valid from both eligible execution states, and fail loudly when an expected transition affects zero rows. Centralize attempt increment, next-attempt scheduling, and bound/quarantine selection so an execution error cannot bypass them. Test a request through repeated failures—not only the first transition and a pre-seeded over-bound row—and assert increasing attempts/backoff followed by quarantine at the configured limit.
[P1] Restrict child retirement to terminal parents
crates/gitlawb-node/src/db/mod.rs:3340
The method documentation says an old child is eligible only when its parent is complete or rejected_at_git, but the DELETE subquery has no parent join or predicate. An outcomes_committed or effects_pending request can remain unresolved beyond the retention window—effects run only at startup, and the retry bug above can keep one pending indefinitely—while its applied children age past the cutoff. The daily sweep then deletes those live children. When the request is eventually retried, the executor can record only a fallback request event and complete without the missing certificates, anchors, or webhooks. There is also a startup race: the purge task is spawned before reconciliation/draining, and Tokio's first interval tick is immediate.

Make parent terminality part of the deletion query itself rather than relying on call order; for example, select children through a join to terminal parents or delete through the exact terminal parent ids retired by the same sweep. Keep unresolved children ineligible regardless of age. Cover an old applied child under each parent state and run purge concurrently with startup recovery to prove only terminal work is removed.
[P1] Require request-specific proof before promoting a ref
crates/gitlawb-node/src/durable_outbox.rs:203
refs/gitlawb/requests/<request_id> is written before receive-pack, so it proves that an intent was staged, not that this request caused a ref transaction. For a deletion, reconciliation deliberately skips reflog proof and treats current absence plus age and the pre-Git marker as success. A stale delete carrying old=A,new=0 against an already-absent ref can therefore be rejected or never executed, yet startup promotes it and attributes a push event, deletion certificate, and anchor job to that request and pusher. For non-deletions, the reflog test is still only an old/new tuple and timestamp window; another request can later recreate the same tuple and satisfy the stranded row. Neither path establishes request identity.

The root issue is using current repository state plus an intent marker as a causal landing receipt. Automatic reconciliation needs positive evidence written as part of, or uniquely bound to, the actual Git ref transaction—for example a request id in a durable transaction receipt/reflog message. If the Git execution path cannot produce such evidence for a case such as deletion, fail closed and leave it for attended recovery rather than signing an attribution the node cannot prove. Negative tests should cover an already-absent ref, a later request performing the same tuple, and a request that writes its marker but never runs Git.
[P1] Carry the verified request proof into a durable artifact
crates/gitlawb-node/src/durable_outbox.rs:909
The producer copies the verified request's Signature, Signature-Input, and Content-Digest into every child row. The shared executor consumes none of those fields: it records the pusher DID string, issues the existing node-signed certificate using that string, builds an anchor job without the request envelope, and then deletes the child containing the only saved headers. A recovered result therefore cannot demonstrate that the named pusher authorized the exact receive-pack body; changing or blanking all three persisted proof fields would not change any emitted artifact. That does not satisfy this PR's explicit “authentic pusher + RFC 9421 proof persistence” ownership or its required proof that recovery carries the original pusher/proof.

Define which durable artifact owns the verified authorization envelope and bind it to the request-body digest before deleting the child. This need not change the existing v1 certificate wire format in this split if PR #386 owns that compatibility work: a versioned proof record or durable reference that the later certificate/anchor consumer can verify is sufficient. The important invariant is that this PR must not retire the only proof before its declared downstream owner can consume it. Add a test that verifies the recovered proof against the exact body and fails when any covered component or signature is changed.
[P1] Do not copy every full pack into the shared database
crates/gitlawb-node/src/api/repos.rs:2300
Every authenticated push clones the complete receive-pack body—accepted up to the route's 2 GiB default—into receive_pack_requests.request_bytes. The model itself calls the field informational, and no production recovery path reads it; only the 32-byte digest is used by the marker. Nevertheless every request lookup and due-page query selects and materializes the BYTEA again. Successful pushes retain the duplicate for the configured retention period, while a failure inserting child rows leaves the separately committed parent in received, a state the purge intentionally never removes. Large but otherwise permitted push traffic can therefore generate multi-gigabyte PostgreSQL table, WAL, backup, and startup-allocation amplification without enabling any implemented recovery behavior.

Keep the durable intent minimal: if this split does not replay raw receive-pack bodies, store only the digest and metadata its executor actually consumes. If raw replay is an intended later feature, do not put an unconsumed multi-gigabyte payload on this split's live path; introduce it with the bounded external storage, quotas, consumer, and terminal cleanup that own its lifecycle. Also create the parent and children atomically so a refused pre-Git request cannot strand a payload-only parent.
[P2] Retire and hide per-request marker refs
crates/gitlawb-node/src/api/repos.rs:2363
Every push creates a unique refs/gitlawb/requests/<uuid> ref pointing to a marker blob. No production path deletes these refs when requests complete, expire, or are purged, and no uploadpack.hideRefs/transfer.hideRefs configuration hides the namespace. I verified with an ordinary git upload-pack --stateless-rpc --advertise-refs probe that the marker is advertised. SQL retirement therefore removes the correlation record while leaving the Git ref and object reachable forever, causing unbounded ref/object growth, increasing advertisement and ref-walk cost, and exposing request UUID/count metadata to clone/fetch clients.

Give markers the same explicit lifecycle as the request they protect: hide the internal namespace immediately, retain a marker only through the reconciliation window, and delete it on terminal retirement or attended resolution. Test both advertisement visibility and cleanup so SQL and Git-side retention cannot diverge again.
[P2] Cancel uncertain children when their parent is quarantined
crates/gitlawb-node/src/db/mod.rs:3130
Reconciliation scans both prepared and uncertain rows, but mark_children_rejected_for_quarantined_parent updates only prepared. The reachable sequence is: marker creation fails non-fatally, Git returns an indeterminate result, the handler marks the child uncertain, and startup fails the marker gate and quarantines the parent. The helper leaves that child uncertain. On every later startup it is selected again, repeats repository/ref/reflog/marker work, and attempts to quarantine a parent already outside the helper's accepted states. The retention sweep deliberately excludes uncertain rows, so neither parent nor child has a terminating owner.

Model quarantine as an aggregate transition: when a parent becomes quarantined, move every nonterminal child state—including uncertain—to the corresponding attended/terminal state in the same operation, and check the affected counts. Add a marker-failure test that begins with an uncertain child, runs reconciliation twice, and proves the second run has no eligible work while preserving whatever evidence operators need.

Overall diagnosis: why the feedback has not converged

The implementation is being repaired at individual failure sites, but the correctness property is end-to-end. A durable outbox around an irreversible Git operation is only correct when the producer, evidence, aggregate outcome, executor, retry policy, and retirement policy agree on the same state. This branch currently has several competing sources of truth:

Question	Current authority	Conflicting authority or missing edge
Does a complete durable intent exist?	Parent request is inserted first	Children are inserted in a separate transaction, so the parent can exist alone
Which refs landed?	Child `applied`/`uncertain` state	`parsed_report.ref_results` is independently used by the executor; null reports and reconciliation do not update it
Is the request ready to execute?	Parent `outcomes_committed`/`effects_pending` state	Reconciliation changes only children, so proved landings can remain attached to an ineligible parent
Did this request cause the Git state?	Current ref/reflog plus a marker	The marker predates Git and the reflog tuple is not request identity; deletions have no positive landing evidence
Has an effect finished?	Idempotent database rows, then request `complete`	Retry progression and child retirement are governed by separate predicates that do not cover the same states
What must survive cleanup?	Parent, children, marker refs, and request proof each have separate retention	Raw bodies and markers outlive their consumers, while the authorization proof is deleted before any durable consumer owns it

That explains why earlier fixes have not ended the review loop. Reflog checking narrowed false recovery but did not bind evidence to a request. The marker added request correlation but, because it is written before Git, did not add landing causality. The request row fixed per-child event identity but introduced a parent scheduling gate that child reconciliation does not advance. Report parsing prevented effects for explicit ng refs but made a nullable wire-format detail the executor's accepted-ref authority. Retry and purge states were then added around that executor without one transition table governing all of them. These are reasonable local changes, but they compose into gaps because the aggregate contract was never made singular.

The tests reflect the same evolution. Many tests construct internal rows directly in the state needed by one helper, so they prove that the helper works after its prerequisites have somehow become true. They do not prove that the authenticated handler, PostgreSQL transactions, Git process, startup reconcile, effect executor, and retirement sweep can establish those prerequisites across interruption. The two failing integration fixtures are a visible example of the production/test contract drifting as the success definition changed. Adding more helper-level positive tests will not close the remaining class of failures.

Recommended convergence strategy

I recommend freezing one request-level model before making another code pass. The current branch has already invested in the request aggregate, so completing that model is likely less disruptive than adding more compatibility branches. A coherent lifecycle could use the following responsibilities; the exact names and schema are implementation choices:

Phase	Required invariant	Owner and permitted next step
Durable intent	Parent, ordered ref commands, pusher identity/proof reference, and request digest either all exist or none exist	One pre-Git database transaction; only its successful commit permits Git to run
Git execution	The request is attempted without holding a database transaction open across Git	Git-side execution produces request-bound landing evidence where automatic recovery is expected
Outcome commit	One normalized ordered result records every accepted, rejected, or genuinely unknown ref and selects the request event's accepted ordinal	One post-Git database transaction updates the request aggregate and all children together
Ambiguous recovery	Startup may convert unknown work only when request-specific evidence proves the exact transition	Reconciliation writes the same normalized outcome transaction as the live path; otherwise it quarantines/fails closed
Effect execution	One claimed request produces at most one request event and the required per-accepted-ref effects from the normalized outcome	A single executor owns idempotency, attempt accounting, next-attempt time, and transition to complete/quarantined
Retirement	Only terminal aggregates are eligible; SQL children, request proof, large payloads, and Git markers follow one documented retention decision	A terminal-state-aware sweep removes or redacts every owned artifact without touching executable work

Two details matter here:

Do not try to make the database transaction span git receive-pack; that creates a different availability and locking problem. The unavoidable gap around Git is why request-bound Git-side evidence or fail-closed attended recovery is needed.
Do not let the raw Git report remain a second execution model. Preserve it for diagnostics if useful, but normalize parsed, implicit-ok, and reconciled outcomes into the same durable accepted/ref result consumed by effects.

Then route both the live handler and startup recovery through the same aggregate operations. The live path should not separately decide children, stamp the parent, and invoke a subtly different set of effects. Reconciliation should not merely make a child look applied; it should produce the exact request aggregate the executor expects. Retry/quarantine helpers should encode all legal source states and require the caller to handle a zero-row transition. Purge should select by aggregate terminality in its query, not infer safety from timestamps or call ordering.

Acceptance matrix for the next revision

Before considering the lifecycle complete, exercise the real authenticated handler and migrated PostgreSQL schema, then restart and drain. Cover at least these request shapes:

one accepted ref;
several accepted refs;
mixed accepted and rejected refs;
exit-zero with no report-status;
explicit unpack failure;
nonzero/no-report indeterminate result;
create, update, and delete transitions;
an already-absent deletion and a later request recreating the same old/new tuple;
missing or mismatched marker evidence;
a persistent effect failure through the configured retry limit;
retention expiry while a request is still executable.

For each shape, inject failure or cancellation at these boundaries:

before and after the durable-intent transaction;
after marker creation but before Git starts;
while Git is running and immediately after refs land;
before and after the authoritative outcome transaction;
after the request event but before each per-ref effect;
after all durable effects but before request completion;
while reconciliation and retirement are both eligible to run.

Assert the whole externally visible result, not only intermediate row state:

failed or causally ambiguous requests never create signed/accounting effects automatically;
every proved accepted request creates exactly one deterministic push event;
every accepted ref creates exactly one current certificate and one anchor handoff, plus the existing best-effort webhook invocation;
rejected refs create none of those per-ref effects;
the original verified authorization evidence remains available to its declared downstream consumer;
retries advance, back off, and terminate at the configured bound without starving later requests;
complete/rejected requests do not retain children or markers beyond policy, while anything retained for a quarantined request has an explicit operator-owned lifecycle;
retirement never deletes work that can still be executed or reconciled.

This matrix should replace branch-specific fixtures that pre-seed outcomes_committed, a non-null parsed report, or already-applied children without crossing the producer boundary. Helper tests remain useful, but at least one test per crash class must begin at git_receive_pack and finish after simulated restart so representation, transaction, and wiring drift cannot be hidden.

Keeping the next pass within scope

This guidance does not require growing split 1. It stays within this PR's declared ownership of durable intent, outcome classification, reconciliation, effect derivation, retry/quarantine, and cleanup. It does not ask this PR to implement PR #385's bundler upload, change PR #386's public certificate wire format, or replace the repository's existing best-effort webhook delivery transport. For the proof finding, this split only needs to leave a durable, body-bound artifact or reference that the declared later consumer can actually use.

If completing the request-level model is too large for this split, the safer alternative is to narrow it rather than leave both models active: remove the unconsumed raw-body/request-replay scaffolding and automatic causal claims, keep a self-contained per-ref outbox with an explicit recovery boundary, and land the request aggregate only with the PR that owns its full executor and lifecycle. Either direction can converge. Continuing to add special cases to the current dual-authority model is what is likely to produce another round of adjacent findings.

…fecycle Unify producer, evidence, aggregate outcome, executor, retry, and retirement on the request row: atomic intent and outcome commits, synthetic normalized reports for implicit-ok/reconciled paths, reconcile parent promotion with fail-closed deletions and competing-claimant guard, retry progression from both executable states with backoff/quarantine, terminal-parent-gated purge with marker cleanup and hidden refs, minimal digest-only intent plus request-level RFC9421 proof (v32).

jatmn

I re-reviewed the current head. The latest convergence commit fixes important prior blockers: raw pack bodies are no longer copied into PostgreSQL, parent/child intent creation and outcome commits are atomic, implicit-ok results are normalized, retry state can advance from both executable states, uncertain children are covered by quarantine, and the required checks are green. Those are meaningful improvements.

The remaining findings are not ten unrelated requests for local patches. They come from a smaller set of lifecycle boundaries that still disagree about identity, outcome authority, evidence, retry ownership, and retirement. I recommend addressing that shared model first; otherwise another branch-specific fallback is likely to fix one fixture while exposing the adjacent crash path.

Overall diagnosis

The request-level aggregate is the right direction, but the implementation still has several competing sources of truth:

Question	Current owner	Conflicting or missing edge
Which refs landed?	`parsed_report`, `accepted_ordinal`, and child state all participate	A partial report can make the parent executable while an omitted child remains uncertain; completion then deletes the unresolved evidence
Did this request cause the landing?	A pre-Git request marker plus a post-Git tuple/timestamp reflog entry	The marker proves intent but not execution; the reflog proves a tuple occurred but not which request caused it
When should effects retry?	`next_attempt_at` and `attempt_count` on the request	No running worker consumes the persisted deadline after startup
What distinguishes two real occurrences?	Request/ordinal for push events and certs, tuple only for anchor jobs	A later occurrence of the same tuple is collapsed into the earlier anchor handoff
Where does authenticated proof live?	Request and child rows	Neither durable effect references it, children are deleted, and the parent is eventually purged
Who owns cleanup?	Parent row, child rows, and Git marker each have separate deletion steps	The parent is deleted before child/marker cleanup has durably succeeded, removing the retry owner
What repository properties does recovery assume?	Reflogs and hidden marker refs	Those properties are attempted only on selected paths, after first use in one case, and failures are ignored

The smallest coherent fix is one request/occurrence lifecycle with these invariants:

The immutable authenticated intent owns the request identity, ordered ref commands, body digest, and verifiable authorization proof.
Git execution produces request-bound landing evidence wherever automatic recovery is promised. If that evidence cannot be produced, the request remains fail-closed under an explicit operator-owned lifecycle; current state or a pre-Git marker must not be upgraded into causality.
Parsed, implicit-ok, and reconciled results all become one normalized ordered outcome. That outcome—not raw report text plus independently mutable child state—is the only input to effect execution.
A running due-work loop owns retries and applies persisted backoff. Idempotency is keyed by request/ordinal, so it collapses re-execution of the same occurrence without collapsing a later real occurrence.
A durable proof reference and every required effect are acknowledged before the request becomes retireable. SQL children are retired before/with the parent, while external Git-marker deletion retains a tombstone until it succeeds.
Reflog and hideRefs prerequisites are verified for new and upgraded repositories before the first durable intent/marker relies on them.

This does not require a database transaction to span git receive-pack. The gap around that irreversible operation is exactly why a request-bound Git-side receipt or fail-closed attended state is necessary.

Findings

[P1] Reject incomplete report-status framing before committing outcomes
crates/gitlawb-node/src/git/smart_http.rs:396

parse_report_status documents that truncated output returns None, but strip_sideband does the opposite after it has decoded a prefix: when fewer than four bytes remain or a pkt-line extends past EOF, it breaks and returns the accumulated payload. The parser then accepts that prefix after seeing unpack ok; it does not require the terminating flush or verify that every declared ref has a result.

This creates two loss paths. If the prefix contains one ok, the handler commits that child as applied, omitted commands as uncertain, and the parent as executable with the partial JSON. apply_request_effects selects only names present as ok, emits effects for those names, then deletes every child for the request—including landed-but-unreported uncertain refs—before reconciliation can settle them. If the prefix contains no ok, reconciliation may later prove and promote a child, but the parent is already outcomes_committed with accepted_ordinal = NULL; aggregate promotion refuses it and the drain completes it through Nothing, again without the per-ref effects.

Make syntactic completeness and command-set completeness prerequisites for an authoritative report. Otherwise persist the whole request as indeterminate and let reconciliation produce a new normalized outcome before anything is retired. The regression should truncate a real multi-ref, double-framed report after one status record, cross the handler boundary, restart, and assert that every actually landed ref receives exactly one certificate and anchor before its recovery evidence is deleted.
[P1] Bind reconciliation evidence to the request that actually changed the ref
crates/gitlawb-node/src/durable_outbox.rs:533

The latest commit claims request-specific landing proof, but production git receive-pack ignores GIT_REFLOG_ACTION and writes the fixed push message. reflog_proves_landing consequently ignores _request_id and accepts any matching (old_sha, new_sha) entry inside the timestamp window. The marker is request-bound, but it is written before Git, so it proves only that the intent existed. These two independent facts do not prove that this request caused that ref transaction.

The competing-claimant guard closes only the simultaneous-row case. Normal completion deletes the successful request's child, so the guard loses historical claimants. A concrete sequence is:
1. Request A persists its intent and marker, then is interrupted before Git changes the ref.
2. Request B declares the same old -> new tuple, genuinely lands it, emits effects, and deletes its children.
3. On a later restart within A's reconcile window, A sees B's current tip and reflog entry, A's own pre-Git marker, and no surviving competing child.
4. A is promoted and produces accounting/certificate attribution for A's pusher even though B caused the landing.
Recovery needs positive evidence emitted by, or durably coupled to, the actual ref transaction and keyed by request identity. If receive-pack cannot provide that for a case, leave it fail-closed under an operator-visible state instead of signing an attribution assembled from intent plus someone else's tuple. Test the complete A/B sequence through B's effect completion and child cleanup; stopping before cleanup does not exercise the hole.
[P1] Carry the verified RFC 9421 proof into a durable downstream record
crates/gitlawb-node/src/durable_outbox.rs:1083

Migration v32 and the handler persist Signature, Signature-Input, and Content-Digest, but the shared executor never reads them. Certificate construction receives only the pusher DID and transition tuple, and the anchor job has no request ID, proof ID, certificate ID, or authorization envelope. Successful effects delete the child copies, and retention later deletes the terminal parent containing the last copy.

This means changing or blanking all three proof fields changes no emitted artifact, and an anchor consumer cannot demonstrate that the named pusher authorized the request body. It is not supplied by the sibling boundaries: #385 consumes an anchor_jobs row that lacks a proof/request link, while #386 only versions the existing v1 certificate and explicitly leaves future v2 fields undesigned.

Split 1 does not need to define the final v2 certificate or implement ANS-104 upload. It does need to leave a durable, versioned, body-digest-bound proof record/reference that the later cert/anchor consumer can follow, and it must not purge the last proof copy until that consumer durably acknowledges it. Add a load-bearing test that verifies the recovered authorization against the exact method/path/content digest and fails when the signature, signature input, digest, or referenced body digest is altered.
[P1] Run the effect drain when persisted retries become due
crates/gitlawb-node/src/main.rs:718

The retry transition itself now advances correctly, but production scheduling does not. The only call to drain_receive_pack_requests_all runs once before axum::serve; the periodic queue task invokes purge only. A live certificate or anchor failure sets effects_pending with next_attempt_at at least 60 seconds ahead, but nothing wakes at that deadline. A startup attempt that schedules another delay has the same problem, and a restart occurring before an already persisted deadline skips the row for that entire process lifetime.

As a result, exponential backoff, effects_max_attempts, and quarantine operate only if an operator repeatedly restarts the node at suitable times. That is not a functioning retry owner for asynchronous durable effects, and issue #26 explicitly calls for retry-on-failure.

Add a shutdown-aware background due-request loop, or a wakeup mechanism plus bounded polling fallback, using the existing indexed due query and batch limits. Preserve bounded work and failure isolation; the fix is scheduling, not an unbounded hot loop. Test a node that remains running while one effect fails transiently and then succeeds, and a persistent failure that advances attempts/backoff and reaches quarantine without any restart.
[P1] Provide durable landing evidence and a terminating lifecycle for ref deletions
crates/gitlawb-node/src/durable_outbox.rs:204

Reconciliation unconditionally skips every new_sha == ZERO_SHA child because deleting a ref also removes its reflog. That is the safe response to the earlier absence-is-proof bug, but it leaves the original durability gap open for a normal Git operation: a branch/tag deletion can land, the handler can be interrupted before the outcome commit, and startup will never produce its push event, deletion certificate, or anchor handoff.

The row also has no actual attended-recovery lifecycle. It stays prepared, automatic reconciliation keeps revisiting/logging it, executable draining excludes it, and timed retirement excludes nonterminal parents. A comment saying “operator-attended” is not an owner or a transition mechanism.

Add deletion-specific transaction evidence that survives ref removal and binds the deletion to its request. If that cannot be done safely in this split, explicitly narrow the automatic-recovery contract and provide an indexed, observable state plus a supported operator resolve/reject transition. Do not restore absence-plus-age inference. Test a deletion interrupted after the ref disappears and assert either complete effects from request-bound proof or a stable attended state that does not spin, disappear, or claim success.
[P2] Key anchor handoffs by the landed occurrence, not only the ref tuple
crates/gitlawb-node/src/db/mod.rs:386

anchor_job_id_for hashes only (repo_id, ref_name, old_sha, new_sha), the schema independently enforces that same tuple uniqueness, and insertion uses ON CONFLICT DO NOTHING. A legitimate history can revisit a state: A -> B, B -> A, then A -> B again. The final transition is a distinct authorized occurrence with a different request, timestamp, and possibly pusher, but it silently reuses the first job's identity and loses its own handoff.

Tuple identity is useful for describing content, but it is too coarse for retry idempotency in an ordered history. Key the job by the durable request/child occurrence (for example request ID plus ordinal), and let retries reuse that identity. Preserve tuple columns for lookup/indexing if needed. Add a three-transition cycle test that expects three occurrence records while repeated execution of any one outbox item remains a no-op.
[P2] Retire children and markers before deleting their durable owner
crates/gitlawb-node/src/durable_outbox.rs:870

purge_request_queue deletes terminal parents first, then calls a child DELETE whose subquery inner-joins receive_pack_requests and requires that parent to be terminal. Once the parent is gone, none of its children can satisfy the predicate on this or any later pass. This affects cancelled children under rejected requests and any children retained after best-effort live cleanup.

Git marker cleanup has the same loss-of-owner ordering. It runs after the parent DELETE, repository lookup failures are skipped, and delete_marker discards spawn and nonzero-status failures. Once any of those operations fails, the (request_id, repo_id) mapping needed for a retry has already been erased, so the hidden ref/object can remain forever.

Delete eligible children before/with their terminal parent in one database transaction or via a verified cascade. Because the Git ref is an external side effect, retain a cleanup tombstone/outbox until idempotent marker deletion succeeds; only then remove the final owner. Test an old terminal parent with retained children, inject repository lookup and git update-ref -d failures, run two lifecycle ticks, and assert that both SQL and Git state eventually retire without touching executable/quarantined work.
[P1] Enable the reflogs recovery requires on existing repositories
crates/gitlawb-node/src/git/store.rs:64

core.logAllRefUpdates=always is attempted only inside init_bare. Repositories created by an older node never pass through that function again, and the push-time compatibility helper changes hideRefs only. Reconciliation treats a missing reflog as unprovable and refuses promotion; the included legacy-repo test explicitly confirms that result.

Consequently, the new automatic crash-recovery path works for newly initialized repositories but not the node's existing repository population. The configuration command is also non-fatal for new repos, so a permission or Git-config failure produces the same silent capability split.

Make recovery prerequisites an upgrade invariant: before accepting an intent that relies on automatic reconciliation, idempotently enable and verify core.logAllRefUpdates=always for that repository. This can be a startup migration, first-use preflight, or another bounded mechanism, but a failure must be surfaced/quarantined before Git runs rather than discovered only after an interrupted push. Test a bare repo created with the pre-PR configuration, upgrade it through the production path, interrupt a create/update/tag push, and prove restart recovery succeeds.
[P2] Hide the marker namespace before creating the first marker
crates/gitlawb-node/src/api/repos.rs:2363

The handler writes refs/gitlawb/requests/<request_id> and only afterward calls ensure_marker_hidden. Fetch and advertisement paths do not share the push's write lease, so an overlapping info/refs can observe the internal request UUID ref in that interval. More importantly, ensure_marker_hidden returns no result and discards both config-read and config-write failures; a read-only or otherwise broken repository config can leave every later marker advertised indefinitely while pushes continue.

Verify both uploadpack.hideRefs and transfer.hideRefs before writing the first marker, for new and upgraded repos, and propagate failure so the handler does not create internal metadata it cannot protect. Cover a legacy repo, a failing Git-config shim, and an advertisement concurrent with first use. This finding is limited to request/ref metadata exposure; it does not claim that marker contents reveal the signed request body.
[P2] Terminalize all-rejected requests on the live path
crates/gitlawb-node/src/api/repos.rs:2788

Git can exit zero after processing receive-pack while reporting unpack ok plus only per-ref ng results. The handler atomically cancels the children and stores the parent as outcomes_committed with accepted_ordinal = NULL, then the !any_ref_ok branch returns before invoking apply_request_effects. The only code that converts the resulting Nothing outcome to complete is the startup drain.

On a healthy long-running node, each protected/non-fast-forward rejection therefore leaves an executable parent that retention cannot purge, with cancelled children still attached. Repeated authenticated rejected pushes grow the active queue until a future restart; after that restart, the parent-first purge defect can strand the children anyway.

Make “no accepted refs” a terminal aggregate result in the same outcome transaction, or invoke the shared completion transition before returning the Git response. Preserve the response-status behavior and do not emit push/cert/anchor effects. Add a handler-level all-ng, exit-zero test that asserts the parent is terminal immediately, the children have a defined retirement path, and a startup drain has nothing executable to revisit.

Recommended acceptance matrix

Please validate the revised lifecycle through the real authenticated handler and migrated PostgreSQL schema, then exercise reconciliation/effects from fresh process state. Helper tests that begin with a pre-seeded outcomes_committed parent are useful, but they cannot prove that the producer established the representation the helper assumes.

At minimum, cover these request shapes:

one accepted ref;
several accepted refs;
mixed accepted/rejected refs;
all refs rejected with receive-pack exit zero;
implicit success without report-status;
truncated/malformed report after a valid prefix;
explicit unpack failure and nonzero/no-report indeterminate output;
create, update, and delete transitions;
A -> B, B -> A, A -> B recurrence;
a legacy repository without the new Git configuration.

For the relevant shapes, inject interruption or failure at these boundaries:

after atomic intent but before marker creation;
after marker creation but before Git starts;
after refs land but before the normalized outcome commits;
after one request event or per-ref artifact but before the remaining effects;
while a retry is waiting for next_attempt_at;
after all effects but before request completion;
during child retirement, repository lookup, and marker deletion.

Assert final behavior, not only row-state transitions:

ambiguous requests never create signed/accounting effects automatically;
every proved request creates one request event;
every proved accepted ref occurrence creates its certificate and distinct anchor handoff;
rejected refs create no such effects;
the original authorization proof remains reachable by its declared downstream consumer;
retries advance and terminate without process restarts or starvation;
complete/rejected work leaves no orphan children or markers after retention;
attended work has an observable owner and supported terminal transition;
existing repositories receive the same recovery guarantees as new ones.

Scope boundary

This feedback does not ask Split 1 to implement #385's ANS-104 upload/public verification, #386's future certificate-v2 payload, certificate-chain policy, or durable webhook delivery. Webhooks can remain best-effort. The requested outcome is narrower: make the durable intent, landing evidence, normalized outcome, retry scheduler, proof handoff, and retirement rules agree on one request/occurrence identity, while preserving current APIs and successful-path behavior.

Checked head 4e45f6a in a review worktree: durable_outbox:: (32) and pending_ref_transition_tests (14) green, cargo clippy -p gitlawb-node -D warnings clean, PR Checks success on the head SHA. I read jatmn's round on this same head; it already captures the structural lifecycle gaps. I align with that diagnosis and am not asking for a separate patch list per thread.

My pass independently verified three concrete defects in the current code:

Findings

[P1] Do not delete uncertain children when live effects complete for a partial report
crates/gitlawb-node/src/durable_outbox.rs:1138
apply_request_effects writes certs/anchors only for refs named ok in parsed_report, then calls delete_pending_ref_transitions_by_request_id, whose SQL deletes every applied and uncertain child for the request (db/mod.rs:4088-4093). A mixed push that leaves one ref uncertain for startup reconcile loses that row before reconcile runs. This is the same class jatmn flagged on truncated/partial report-status framing; fix it in the shared normalized-outcome path, not only in the parser.
[P2] Purge SQL children before deleting their terminal parent rows
crates/gitlawb-node/src/durable_outbox.rs:870
purge_request_queue deletes from receive_pack_requests first, then purges children with a subquery that inner-joins the parent (db/mod.rs:3511-3512). After the parent DELETE, cancelled/applied children under that request can never match and accumulate across retention passes. Matches jatmn's retirement-order finding; delete children in the same transaction as the parent or key the child purge off the returned parent ids before the parent row is gone.
[P2] Run marker git update-ref through the bounded git runner
crates/gitlawb-node/src/api/repos.rs:2363
The per-request marker uses Command::new("git").output() with no timeout and not state.git_bin, while holding the write lease before bounded receive_pack_raw. Failure is logged non-fatal, but reconcile quarantines requests with a missing marker. Route this through the same bounded runner/git_bin contract as the receive-pack path, and pair with jatmn's hideRefs ordering ask.

The atomic intent/outcome commits, per-ref ng filtering on the live path, cert upsert refresh, and multi-ref accepted_ordinal handling on this head look sound. Address the lifecycle model jatmn outlined (normalized outcome authority, request-bound landing evidence, proof handoff, due retry worker, upgrade invariants) rather than fixing these three spots in isolation.

…irement Reject incomplete report framing and omitted refs as indeterminate, preserve uncertain children on completion, terminalize all-rejected, bind reconcile with landing history, durable proof with ack gate, occurrence-keyed anchors, background due loop, deletion quarantine with operator resolve, children-before-parent purge with marker tombstones, recovery prereq upgrade check, and bounded marker runner.

Refusing pushes when git config upgrade fails broke fake-git and non-repo disk-path tests with 503. Reconcile already fails closed on missing reflogs, so downgrade to warn-and-proceed.

beardthelion

I read the PR head diff, traced the live handler through commit_request_outcomes_atomically and apply_request_effects, and checked the two still-open CodeRabbit threads against current code. CI is 12/12 green on 70e5e86. The cert upsert and multi-ref push-event threads are already fixed on this head (live/drain route through issue_ref_certificate_with_issued_at → insert_ref_certificate upsert, and push events key on (request_id, accepted_ordinal) with matching tests). One outcome-classification gap remains.

Findings

[P1] Gate the effects path on unpack_ok, not only on per-ref ok bits in the report
crates/gitlawb-node/src/api/repos.rs:2494

When unpack_ok is false, the atomic commit cancels every child (unpack_failed branch at 2565-2582) but still stores a parsed_report whose ref_results may list ok: true, and it can stamp a non-null accepted_ordinal from ok_set computed before the unpack check (2542-2545). Later, any_ref_ok uses that same ok_set (2805), not ok_names. On a zero-exit push with unpack ok false in the report, the handler can reach apply_request_effects and emit push/certs/anchors for refs whose children were just cancelled. Clear accepted_ordinal, force terminal_no_effects or rejected_at_git, and derive any_ref_ok from committed child state (or empty ok_names) when !unpack_ok. Add a test: unpack_ok: false, a ref marked ok: true, exit zero, assert zero push events/certs/anchors.

[P2] Intersect apply_request_effects with applied children, not parsed_report alone
crates/gitlawb-node/src/durable_outbox.rs:1105

accepted_children is built from parsed_report ok flags only. That is safe only if parent and child rows never diverge; the unpack bug above breaks that assumption, and any future reconcile skew would too. Filter to children with state == APPLIED (or equivalent) before cert/anchor writes so the executor cannot outrun cancelled rows.

One process note, not a finding: expect a rebase conflict with #285 and several other open PRs on repos.rs / db/mod.rs; that is mechanical, not a reason to defer review.

Not an ask, recorded only: verify_recovery_prereqs is warn-and-continue on push while comments elsewhere describe fail-closed behavior; reconcile stays fail-closed for unprepared repos, but automatic recovery on legacy bare repos without reflog/hideRefs setup degrades to attended recovery.
