+- code-health gates
+- package `pack` dry-run plus tarball-shape verification
+- docs contract (install commands, package status labels, and smoke rows stay
+  in sync)
+- public integration smoke
+- security compliance
+
+**Also in this repository, run in package or release contexts (not the per-PR
+affected lane):**

+- Core OpenAPI generation and drift check (`generate:openapi` / `check:openapi`)
+- Core API schema tests (Schemathesis)
+- Core Docker image smoke (runs in the Docker image publish workflow)

+## Companion: llmwiki
+
+[llmwiki](https://github.com/atomicstrata/llmwiki) is a separate knowledge compiler that turns raw sources into an interlinked markdown wiki. It is **valuable on its own** — useful as a notebook, RAG index, CI-checked knowledge base, or domain pack source — and remains so whether or not AtomicMemory is in the picture.
+
+`@atomicmemory/llmwiki` (in this monorepo at `packages/llmwiki/`) is a one-way bridge: it imports an `llmwiki export --target json` envelope as one verbatim AtomicMemory record per wiki page, with all advisory metadata (kind, citations, confidence, provenance state, contradictions, aliases, freshness) preserved under `memory.metadata.llmwiki.*`. Either direction holds value standalone; the bridge just lets you choose runtime semantic recall on top of compiled knowledge.

+Use `atomicmemory add "<fact>"` for a short text memory. Use `atomicmemory ingest --mode verbatim --content-class summary --file <path>` only when distilled content should be stored as one deterministic record. Use `--content-class redacted` for redacted-but-not-summarized content; do not use verbatim ingest for raw transcripts or secrets.
 
 Prefer `--metadata`, `--source`, and `--source-url` when provenance matters. Never put secrets, credentials, tokens, or private keys into memory.

+/**
+ * @file `atomicmemory import --type llmwiki <export.json>` —
+ * bridge import path for llmwiki JSON exports.
+ *
+ * Calls `@atomicmemory/llmwiki` to parse + validate the export, then
+ * writes each page as ONE verbatim memory record via the provider
+ * adapter.
+ *
+ * **Append-only safety.** AtomicMemory's verbatim ingest is not
+ * idempotent by external ID — every call creates a new memory record.
+ *
+ *  - First invocation (no existing memory matches the imported
+ *    project's external-ID prefix) runs without extra flags.
+ *  - Subsequent invocations REFUSE unless BOTH `--allow-append-only`
+ *    AND `--accept-duplicates` are supplied, because re-imports
+ *    double every page that hasn't changed.
+ *
+ * **Re-import detection is fail-safe.** The walk over the user's
+ * memory list returns a discriminated outcome:
+ *
+ *   - `'none'`         — confidently first import; proceed.
+ *   - `'found'`        — prior import; refuse unless opt-in flags.
+ *   - `'inconclusive'` — list walk exceeded its budget; REFUSE rather
+ *     than risk silent duplicate creation.
+ *
+ * Match criteria require BOTH `provenance.source === "llmwiki"` AND
+ * `metadata.externalId.startsWith(prefix)`. Two signals make
+ * accidental or malicious bypass harder.
+ *
+ * **Scope axes.** The bridge has three identity axes — `user`,
+ * `namespace`, and `projectId`. The external ID encodes only
+ * `projectId`, so an existing import under a *different* namespace
+ * still appears as a "found" hit; we surface that as a warning rather
+ * than silently treating the namespaces as isolated. Pin `projectId`
+ * globally unique per user across namespaces.
+ *
+ * Cross-namespace detection works by probing with `{ user }` only
+ * (namespace and thread stripped). This relies on the active adapter
+ * supporting user-scoped listing without further filtering — the
+ * common case for AtomicMemory-shaped adapters. Adapters that refuse
+ * to list without a namespace will downgrade the cross-namespace
+ * warning to a no-op; same-namespace re-import detection still works.

+## Trusted-Proxy Identity Contract
+
+@atomicmemory/core deliberately does **not** authenticate end users. Two
+distinct credential realities apply to every authenticated `/v1/*` request:
+
+1. **`CORE_API_KEY` authenticates the *caller process*, not the user.**
+   The `requireBearer` middleware validates `Authorization: Bearer <key>`
+   against the single shared `CORE_API_KEY`. Any holder of that key is an
+   authenticated caller — there is no per-user token.
+
+2. **`user_id` is *asserted by the trusted caller*.** The `user_id` carried
+   in request bodies (`user_id`), query strings (`?user_id=`), or the
+   `X-AtomicMemory-User-Id` header (direct-storage routes) is taken at face
+   value. Core trusts the caller to have authenticated that user itself.
+
+### Blast radius
+
+Because the key gates the process and the caller asserts `user_id`, **any
+holder of `CORE_API_KEY` can read or write any user's memories.** A leaked
+key compromises *all* users, not one. There is no per-user isolation at the
+core auth layer.
+
+### Deployment guidance
+
+- **Multi-user hosted deployments:** the control plane (Radar daemon /
+  webapp proxy) must be the **only** holder of `CORE_API_KEY`. It is a
+  *trusted proxy*: it authenticates the end user with its own mechanism
+  (OIDC / session), then calls core on the user's behalf, asserting
+  `user_id`. Untrusted client code (browser extensions, device apps) must
+  never receive the key and must never call core directly — they go through
+  the control-plane proxy. This mirrors the workspace trust-boundary rule:
+  the client cannot hold a credential that asserts `user_id`.
+- **Single-user local deployments:** this is a non-issue. The caller and the
+  user are the same principal, and there is no cross-user blast radius.
+
+### Defense-in-depth: `TRUSTED_PROXY_MODE`
+
+To catch a daemon/proxy bug that silently cross-asserts a *different* user,
+core ships an optional guard. Set `TRUSTED_PROXY_MODE=true` and the trusted
+caller must restate the user it authenticated in the
+`X-AtomicMemory-Asserted-User` header on every user-scoped request:
+
+- The `assertedUserGuard` middleware compares `X-AtomicMemory-Asserted-User`
+  against the request's `user_id` (body/query) or `X-AtomicMemory-User-Id`
+  header.
+- A **mismatch** or a **missing** asserted-user header on a request that
+  carries a user identity fails closed:
+
+  ```
+  403 { "error_code": "asserted_user_mismatch" }
+  ```
+
+- A request with **no** user identity at all passes the guard untouched
+  (routes that require `user_id` still 400 in their own validation).
+- This is defense-in-depth; it does **not** make `user_id` independently
+  trustworthy (the shared key still only authenticates the caller process).
+
+#### Safe-by-default resolution (radar audit #14)
+
+`TRUSTED_PROXY_MODE` is resolved from the deployment env so a hosted,
+multi-tenant deployment cannot accidentally ship with the guard off. The
+deployment signal is `RAW_STORAGE_DEPLOYMENT_ENV` (`production` / `staging` are
+hosted; `local` is single-user):
+
+| `RAW_STORAGE_DEPLOYMENT_ENV` | `TRUSTED_PROXY_MODE` | Effective `trustedProxyMode` |
+|---|---|---|
+| `production` / `staging` (hosted) | unset | **`true`** (guard on by default) |
+| `production` / `staging` (hosted) | `true` | `true` |
+| `production` / `staging` (hosted) | `false` | **startup fails** (refuse to disable the guard in a hosted env) |
+| `local` | unset | `false` |
+| `local` | `true` | `true` |
+| `local` | `false` | `false` |
+
+Non-boolean values for `TRUSTED_PROXY_MODE` are rejected at startup in all
+envs. To run a hosted deployment without the guard you must change the
+deployment env, not silently disable the guard.
+
+### Deferred (not implemented)
+
+Per-user tokens / a multi-tenant auth layer in core (so a leaked credential
+compromises one user instead of all) are a larger future change and are
+**out of scope** here. The current contract assumes a trusted proxy in front
+of core for multi-user deployments.

+# Offline Personal Profile
+
+This document specifies the exact environment configuration for running
+AtomicMemory Core with **zero external network calls** — no OpenAI, no Voyage,
+no HuggingFace Hub fetch at runtime. This is the supported profile for
+Radar Personal deployments that must operate fully air-gapped or on networks
+without cloud API access.
+
+## No-External-Calls Guarantee
+
+When the configuration below is applied:
+
+- Embeddings are computed locally by the `transformers` provider (ONNX Runtime
+  via `@huggingface/transformers`). No request is ever sent to `api.openai.com`,
+  `api.voyageai.com`, or any other external embedding endpoint.
+- Ingest uses `/ingest/quick?skip_extraction=true`, which stores the caller's
+  pre-extracted facts directly without invoking any LLM CLI. No `claude-code`,
+  `codex`, or other LLM process is spawned.
+- The database is local Postgres + pgvector (Docker image uses an embedded
+  instance by default).
+
+**In this profile, the AtomicMemory Core server makes NO external network
+calls during normal operation.**
+
+> Note: the model weights themselves must be downloaded once before the first
+> run (see Pre-cache step below). After pre-caching, no network access is
+> needed for any subsequent start or request.
+
+## Exact Environment Combo
+
+```env
+# Offline Personal profile — zero external network calls
+
+# Local ONNX embeddings (no API key required)
+EMBEDDING_PROVIDER=transformers
+EMBEDDING_MODEL=Xenova/all-MiniLM-L6-v2
+EMBEDDING_DIMENSIONS=384
+
+# Offline mode guard: rejects cloud embedding AND cloud LLM providers at startup
+OFFLINE_MODE=true
+
+# A local LLM_PROVIDER is REQUIRED under OFFLINE_MODE=true. The default
+# LLM_PROVIDER is `openai` (a cloud provider), so it must be set explicitly to
+# a local provider even if you only use the zero-LLM quick-ingest path —
+# otherwise startup fails fast. Allowed local LLM providers:
+#   LLM_PROVIDER=claude-code   # uses local Claude Code CLI, no Anthropic API key
+#   LLM_PROVIDER=codex         # uses local Codex CLI, no OpenAI API key
+#   LLM_PROVIDER=ollama        # uses a local Ollama daemon only
+LLM_PROVIDER=claude-code
+
+# Local Postgres + pgvector (Docker image embeds one by default)
+DATABASE_URL=postgresql://atomicmemory:atomicmemory@localhost:5433/atomicmemory
+
+# Raw-content policy: single-user local deployments may allow any content class
+RAW_CONTENT_POLICY=allow
+
+# Required at startup
+CORE_API_KEY=replace-with-a-strong-random-secret
+STORAGE_KEY_HMAC_SECRET=<64-hex-chars>
+RAW_STORAGE_DEPLOYMENT_ENV=local
+```
+
+## Pre-cache Step
+
+The `transformers` provider downloads the ONNX model from HuggingFace Hub on
+the **first run** only, then stores it in a local cache directory. Subsequent
+starts and all inference use only the cached files — no network access.
+
+To pre-download the model **before** going offline:
+
+```bash
+# Set the cache directory (optional — defaults to the HuggingFace transformers
+# cache, typically ~/.cache/huggingface/hub or $HF_HOME/hub).
+export TRANSFORMERS_CACHE=/path/to/your/model-cache
+
+# Run a one-shot embed to trigger the download (any non-empty string works):
+curl -s -X POST http://localhost:17350/v1/memories/search \
+  -H "Authorization: Bearer $CORE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"query":"warmup","user_id":"warmup"}' \
+  | head -c 200
+```
+
+Alternatively, use the HuggingFace CLI to download the model files directly:
+
+```bash
+pip install huggingface_hub
+huggingface-cli download Xenova/all-MiniLM-L6-v2 \
+  --local-dir /path/to/your/model-cache/Xenova/all-MiniLM-L6-v2
+```
+
+After the cache is populated, the server can be started without any internet
+access and will serve the model from the local cache on every run.
+
+> **Do not commit ONNX model weights.** Model files are large binary artifacts
+> that belong in ops-managed storage (Docker volume, persistent disk, etc.),
+> not in the repository. The cache directory should be in `.gitignore`.
+
+## Zero-LLM Ingest Path
+
+The `/ingest/quick?skip_extraction=true` endpoint accepts pre-extracted facts
+and stores them directly without invoking any LLM. This is the primary ingest
+path for the Offline Personal profile.
+
+```bash
+curl -X POST "http://localhost:17350/v1/memories/ingest/quick?skip_extraction=true" \
+  -H "Authorization: Bearer $CORE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "user_id": "user-123",
+    "memories": [
+      { "content": "The project deadline is end of Q3." }
+    ]
+  }'
+```
+
+The full `/ingest` endpoint (which calls an extraction LLM to produce memories
+from raw conversation text) requires a local LLM CLI when offline:
+
+- `LLM_PROVIDER=claude-code` — uses the local [Claude Code](https://claude.ai/code)
+  CLI. No `ANTHROPIC_API_KEY` is required; the CLI handles auth locally.
+- `LLM_PROVIDER=codex` — uses the local [Codex](https://openai.com/blog/openai-codex)
+  CLI. No `OPENAI_API_KEY` is required; the CLI handles auth locally.
+
+## Offline Mode Guard
+
+Setting `OFFLINE_MODE=true` adds a startup validation step that rejects **both**
+the `EMBEDDING_PROVIDER` and the `LLM_PROVIDER` if either would make external
+network calls. The LLM provider matters because the full `/v1/memories/ingest`
+extraction path calls the LLM provider — a cloud LLM under offline mode would
+silently reach a cloud API. This ensures a misconfigured offline deployment
+fails fast at startup with a clear error message rather than degrading into
+cloud calls when the first request arrives.
+
+> The default `LLM_PROVIDER` is `openai` (cloud). Under `OFFLINE_MODE=true` you
+> MUST set `LLM_PROVIDER` explicitly to a local provider — even on the
+> zero-LLM `skip_extraction=true` quick-ingest path — or startup fails.
+
+Accepted embedding providers under `OFFLINE_MODE=true`:
+
+| Provider | Network calls |
+|---|---|
+| `transformers` | None after model is pre-cached |
+| `ollama` | None (calls local Ollama daemon only) |
+
+Rejected embedding providers under `OFFLINE_MODE=true`:
+
+| Provider | Rejected because |
+|---|---|
+| `openai` | Calls `api.openai.com` |
+| `voyage` | Calls `api.voyageai.com` |
+| `openai-compatible` | Calls a configurable remote endpoint |
+
+Accepted LLM providers under `OFFLINE_MODE=true`:
+
+| Provider | Network calls |
+|---|---|
+| `claude-code` | None (local Claude Code CLI handles auth locally) |
+| `codex` | None (local Codex CLI handles auth locally) |
+| `ollama` | None (calls local Ollama daemon only) |
+
+Rejected LLM providers under `OFFLINE_MODE=true`:
+
+| Provider | Rejected because |
+|---|---|
+| `openai` | Calls `api.openai.com` |
+| `anthropic` | Calls `api.anthropic.com` |
+| `groq` | Calls `api.groq.com` |
+| `google-genai` | Calls Google Generative AI endpoints |
+| `openai-compatible` | Calls a configurable remote endpoint |
+
+## Summary
+
+| Concern | Offline Personal setting |
+|---|---|
+| Embedding | `EMBEDDING_PROVIDER=transformers` + `EMBEDDING_MODEL=Xenova/all-MiniLM-L6-v2` + `EMBEDDING_DIMENSIONS=384` |
+| LLM (ingest) | `LLM_PROVIDER=claude-code` / `codex` / `ollama` (required — cloud default is rejected offline) |
+| Model weights | Pre-cache once to `TRANSFORMERS_CACHE`; not committed to the repo |
+| Database | Local Postgres + pgvector |
+| Content policy | `RAW_CONTENT_POLICY=allow` (single-user local) |
+| Startup guard | `OFFLINE_MODE=true` — fails fast if a cloud embedding OR cloud LLM provider is configured |
+| External calls | **None** after model pre-cache |

+/**
+ * Producer-sourced golden search-response contract (radar audit #5).
+ *
+ * The Radar daemon hand-replicates core's `/search/fast` wire shape in Rust
+ * (`crates/radar-daemon/src/memory/atomicmemory.rs`). Without a producer-owned
+ * fixture, a change to core's serialization silently breaks Radar. This test
+ * pins the canonical search-response object — `count`, the flat `memories[]`
+ * (each with `id`/`content`/`score`/`version_id`/`observed_at`), the C1
+ * `retrieval` receipt, and the `/search/fast` `deterministic: true` flag — by
+ * driving the REAL route + `formatSearchResponse` over HTTP and comparing the
+ * stable-key-order serialization against a committed golden fixture.
+ *
+ * The fixture is the single source of truth for the wire shape: the Radar side
+ * vendors the SAME bytes, and the SDK S4 conformance corpus validates this same
+ * golden against the v1 schemas. Regenerate intentionally with
+ * `UPDATE_CONTRACT_GOLDEN=1`; any unintended drift fails this CORE test, which
+ * is the point — the producer is now pinned.
+ *
+ * Uses the mocked-MemoryService + ephemeral-router pattern (matching
+ * memory-route-retrieval-receipt) so it needs no live Postgres while still
+ * exercising the real formatter and the dev-mode response-schema validator.

+ *
+ *   1. migration 0003's partial UNIQUE index rejects a second LIVE row sharing

+ *      proves "on 23505 we re-read + update"; this proves real Postgres actually
+ *      raises 23505 on the duplicate, so the two together cover the fix.
+ *   2. rows WITHOUT an externalId (NULL) are NOT constrained (partial predicate).
+ *   3. a stored memory resolves by its external id through the real read path
+ *      (`GET /v1/memories/by-external-id` is backed by `findMemoryByExternalId`).

+/**
+ * @file `assertedUserGuard` — defense-in-depth middleware enforcing the
+ * trusted-proxy identity contract.
+ *
+ * Background. In @atomicmemory/core the shared `CORE_API_KEY` (validated
+ * by `require-bearer.ts`) authenticates the *caller process*, NOT the end
+ * user. The `user_id` carried in request bodies/queries is **asserted by
+ * the trusted caller** — the trusted control-plane caller — which must do
+ * its own user authentication first. See `SECURITY.md` ("Trusted-Proxy
+ * Identity Contract") for the blast-radius rationale.
+ *
+ * This guard does NOT replace that contract — it makes the proxy's user
+ * assertion explicit so a daemon/proxy bug cannot silently cross-assert a
+ * different user. When `trustedProxyMode` is enabled, every request that
+ * carries a `user_id` MUST also carry the same value in the
+ * `X-AtomicMemory-Asserted-User` header. A mismatch or a missing header on
+ * a user-scoped request fails closed:
+ *
+ *   403 { error_code: 'asserted_user_mismatch', error: '<reason>' }
+ *
+ * When `trustedProxyMode` is disabled (the default), the guard is a
+ * no-op and behavior is unchanged — single-user local deployments and
+ * existing callers are unaffected.
+ *
+ * Placement. The guard must run AFTER body parsing (`express.json`) so it
+ * can read the parsed wire `user_id`, and BEFORE per-route `validateBody`
+ * transforms rename it to camelCase. It reads the user identity from every
+ * channel core accepts: `req.body.user_id` (POST/PUT bodies),
+ * `req.query.user_id` (GET/DELETE query routes), and the
+ * `X-AtomicMemory-User-Id` header (the direct-storage surface). All are
+ * cross-checked against the asserted-user header.

+# @atomicmemory/llmwiki
+
+Bridge adapter for importing **llmwiki** JSON exports into AtomicMemory.
+
+llmwiki compiles raw sources into an interlinked markdown wiki and can
+emit the result as a typed JSON envelope (`llmwiki export --target
+json`). This package parses that envelope and maps each wiki page to a
+**verbatim** AtomicMemory ingest input — one page becomes one memory
+record, with all advisory metadata (kind, citations, confidence,
+provenance state, contradictions, aliases, freshness) preserved under
+`memory.metadata.llmwiki.*`.
+
+## Install
+
+```bash
+pnpm add @atomicmemory/llmwiki @atomicmemory/sdk
+```
+
+This package is **ESM-only** (`"type": "module"` with no CJS build). CommonJS consumers cannot `require()` it; use ESM imports or wrap via dynamic `import()`.
+
+## Quick start (recommended: CLI)
+
+The shipped CLI wraps the bridge with the re-import probe, the
+`--allow-append-only` / `--accept-duplicates` / `--yes` opt-in gates,
+per-page failure capture, and a non-zero exit code on any partial
+failure. This is the safe path:
+
+```bash
+atomicmemory import --type llmwiki ./wiki.json \
+  --user alice --namespace team-kb
+```
+
+Add `--dry-run` to inspect the envelope (external IDs, byte counts,
+projectId) without ingesting anything.
+
+## Advanced: SDK-direct usage
+
+Calling `toAtomicMemoryIngestInputs` + `provider.ingest()` directly
+gives you the full ingest pipeline but **you take responsibility for
+error handling and rollback** — AtomicMemory verbatim ingest is
+append-only, and a failure partway through a 100K-page wiki leaves
+partial state with no automatic recovery. The CLI is the safer
+default; reach for this only if you need to integrate the bridge into
+custom application code.
+
+```ts
+import { MemoryClient } from "@atomicmemory/sdk";
+import {
+  loadLLMWikiExport,
+  toAtomicMemoryIngestInputs,
+  assertSupportsVerbatim,
+} from "@atomicmemory/llmwiki";
+
+const client = new MemoryClient(/* … */);
+const provider = client.getProvider();
+
+assertSupportsVerbatim(provider);
+
+const exportData = await loadLLMWikiExport("./wiki.json");
+const inputs = toAtomicMemoryIngestInputs(exportData, {
+  scope: { user: "alice", namespace: "team-kb" },
+});
+
+// Per-page failure capture. Partial success is real — a failure on
+// page N leaves pages 0..N-1 already committed to the store and there
+// is no automatic rollback. Track which inputs failed so a retry can
+// be scoped to those.
+const failures: { externalId: string; error: unknown }[] = [];
+for (const input of inputs) {
+  try {
+    await provider.ingest(input);
+  } catch (error) {
+    failures.push({
+      externalId: (input.metadata as { externalId: string }).externalId,
+      error,
+    });
+  }
+}
+if (failures.length > 0) {
+  // Surface to your operator/log path — don't silently swallow.
+  throw new Error(`Partial import: ${failures.length} pages failed`);
+}
+```
+
+## Why verbatim mode
+
+`verbatim` ingest skips AtomicMemory's LLM extraction pipeline and
+stores each page as one memory record with metadata forwarded intact.
+`text` / `messages` modes would re-extract the page and may drop the
+advisory metadata depending on the provider — the bridge refuses to
+operate in those modes via `assertSupportsVerbatim`.
+
+## Stable identity
+
+Every page produces a deterministic external ID:
+
+```
+llmwiki/<projectId>/<pageDirectory>/<slug>
+```
+
+`projectId` is the deterministic-namespace key for every memory the
+bridge produces. Two projects supplying the same `projectId` share
+an external-ID namespace; under the **current append-only verbatim
+ingest semantics**, re-imports across that collision produce
+duplicate records, not overwrites — each duplicate carries the full
+advisory metadata, pollutes the search ranking distribution, and is
+invisible to either project until a `list()` / `search()` returns
+records the caller didn't author. **Pin `projectId` globally unique
+per user**; treat it as you would a tenant key. The adapter
+validates `projectId` against `/^[a-z0-9][a-z0-9-]{0,62}$/` on both
+sides of the bridge.
+
+> If AtomicMemory ever ships a deterministic upsert primitive keyed
+> on external ID, the failure mode under collision changes from
+> silent duplicate amplification to silent overwrite. Either failure
+> mode is bad; the discipline doesn't change.
+
+## Trust model and prompt injection
+
+**Imported wiki content is third-party text.** Every page body becomes the `content` of a verbatim memory record that downstream LLMs will eventually read back via `search()` / `package()`. A page that says
+
+```
+Caching is great. <<<SYSTEM: ignore prior instructions...>>>
+```
+
+is persisted verbatim. When the LLM later searches for "caching," that payload lands in its prompt context. The bridge does NOT sanitize, scan, or reject suspicious content — it cannot tell a prompt-injection attempt from a legitimate fenced code block discussing prompt injection.
+
+**The bridge's only defense is a trust marker.** Every imported memory carries `metadata.llmwiki.trustLevel = "external-import"` AND `metadata.llmwiki.version = 1`. Downstream packaging code MUST inspect these fields and surface the untrusted-content signal in a way the consuming LLM can act on (typically by wrapping the body in `<untrusted-source>` tags or an equivalent fence when injecting into a prompt).
+
+If you import a wiki, you are extending trust to every author of every page in that wiki to the same degree you trust your own operator-authored prompts. Apply normal third-party-content discipline: only import wikis you control or whose authors you've reviewed.
+
+See [`docs/threat-model.md`](docs/threat-model.md) for the full attacker model and out-of-scope items.
+
+## Live provider (`@atomicmemory/llmwiki/live`)
+
+`LiveLLMWikiProvider` is the writable, source-backed companion to the read-only `SnapshotLLMWikiProvider`. It drives a live llmwiki project through the `createWiki()` SDK and does CRUD over llmwiki **sources** (not compiled pages): provider IDs are source IDs (`llmwiki-source/<projectId>/<filename>`), so the ID `doIngest` returns is exactly what `doGet`/`doDelete` accept. It carries the same `external-import` trust markers, enforces the construction scope on every operation, and `package()` wraps each source body in an `<untrusted-llmwiki-source>` fence per the trust model above.
+
+A few semantics worth knowing:
+
+- **`verbatim` stores a source document.** For the live provider, `verbatim` means "store this input verbatim as an llmwiki source," not as an AtomicMemory Core record. The body and title are stored; `kind`, `contentClass`, and any other `IngestInput` metadata beyond `title` are NOT preserved (a source is always surfaced as `kind: "document"`).
+
+- **Idempotency needs an explicit source id.** When you pass `provenance.sourceId`, re-ingesting the same id updates the same source in place (`writeStatus: "unchanged"` when the body is byte-identical). Without it, the source identity is derived from `title + text`, so re-ingesting the same content with an inconsistent `metadata.title` forks a new source instead of updating. **Pass `provenance.sourceId` whenever you need reliable upsert.**
+
+- **`createdAt` is the last-ingest time.** A source carries a single `ingestedAt` timestamp that the SDK re-stamps on every write, so the `Memory.createdAt` the live provider returns reflects the most recent ingest, not original creation — and there is no separate `updatedAt`.
+
+- **`compile()` is explicit and scope-guarded.** Compilation (the LLM step that turns sources into interlinked pages) is a separate `compile(scope)` call, never part of ingest; it requires the construction scope and LLM credentials. Run it after a batch of ingests.
+
+- **`search()` / `package()` load every source body** to score lexically (O(all-sources) per call), and `search()` is not cursor-paginated. Fine for modest projects; a `source`→filename manifest index is the planned scale fix.
+
+### Lazy registration (no compiler load until used)
+
+Importing `@atomicmemory/llmwiki/register` is light — `llm-wiki-compiler` loads only when the provider is constructed during `initialize()`.
+
+```ts
+import { MemoryClient } from "@atomicmemory/sdk";
+import { liveLlmwikiLazyEntry } from "@atomicmemory/llmwiki/register";
+
+const client = new MemoryClient({
+  providers: { "llmwiki-live": { root: "./wiki", projectId: "my-proj", scope: { user: "alice" } } },
+  defaultProvider: "llmwiki-live",
+});
+await client.initialize({ "llmwiki-live": liveLlmwikiLazyEntry() }); // compiler loads only now
+```
+
+- **llmwiki-only clients:** pass `{ "llmwiki-live": liveLlmwikiLazyEntry() }`.
+- **Mixed clients (llmwiki + built-in providers):** this is currently **manual/advanced** — `defaultRegistry` is intentionally not exported and built-in provider factories are not exposed as a public registry. You must assemble the full registry object yourself (one entry per provider). First-class registry composition is deferred to a separate SDK decision.
+- **`@atomicmemory/llmwiki/register`** (light, lazy, for registration) vs **`@atomicmemory/llmwiki/live`** (eager, for direct `new LiveLLMWikiProvider(...)`).
+
+## Limits
+
+The export is treated as untrusted input. Hard caps enforced on every

+## Error codes
+
+All errors thrown by this package are `LLMWikiBridgeError` instances
+with a stable `.code` field. Branch on the code, not the message:
+
+- `E_LLMWIKI_EXPORT_INVALID_SHAPE`
+- `E_LLMWIKI_EXPORT_OVER_LIMIT`
+- `E_LLMWIKI_EXPORT_NOT_FOUND`
+- `E_LLMWIKI_EXPORT_DUPLICATE_SLUG`
+- `E_LLMWIKI_PROJECT_ID_REQUIRED`
+- `E_LLMWIKI_PROJECT_ID_INVALID`
+- `E_LLMWIKI_VERBATIM_UNSUPPORTED`
+- `E_LLMWIKI_PROVIDER_READONLY`
+- `E_LLMWIKI_PROVIDER_SCOPE_MISMATCH`
+- `E_LLMWIKI_PROVIDER_INVALID_CURSOR`
+- `E_LLMWIKI_PROVIDER_INVALID_LIMIT`
+- `E_LLMWIKI_PROVIDER_INVALID_BUDGET`
+- `E_LLMWIKI_PROVIDER_DISPOSED`
+- `E_LLMWIKI_REIMPORT_CHECK_INCONCLUSIVE`
+- `E_LLMWIKI_COMPILER_MISSING` — thrown by `@atomicmemory/llmwiki/register`'s lazy factory when the live provider is selected but the optional peer `llm-wiki-compiler` is not installed. Install it (`npm i llm-wiki-compiler@^0.9.0`) to use `@atomicmemory/llmwiki/register`. (Note: `@atomicmemory/llmwiki/live` imports the compiler eagerly, so a missing peer there fails at import time with a raw module-resolution error, not this code.) A rejected `initialize()` leaves the client in an undefined partial state — construct a new `MemoryClient` after installing the peer (retrying the same instance re-throws the original error). A corrupt install (package present but unloadable) surfaces the raw module-resolution error instead of this code, since reinstalling rather than installing is the fix.
+
+A regression test in `src/__tests__/error-codes-doc.test.ts` asserts every code exported from `errors.ts` appears in this list, so additions can't ship undocumented.

+# llmwiki Bridge Cookbook
+
+Four-step workflow for taking raw sources → compiled wiki → AtomicMemory
+runtime memory → injection-ready context.
+
+## 0. Prerequisites
+
+- `llmwiki` CLI available (see the [llmwiki repository](https://github.com/atomicstrata/llmwiki))
+- An AtomicMemory provider that supports `verbatim` ingest. The
+  `AtomicMemoryProvider` shipped in `@atomicmemory/sdk` qualifies.
+- An AtomicMemory CLI profile already initialized (`atomicmemory init …`).
+
+## 1. Compile the wiki
+
+Inside an llmwiki project, drop your raw sources into `sources/` and
+run the compiler:
+
+```bash
+llmwiki compile
+```
+
+This produces an interlinked markdown wiki under `wiki/`. The wiki is
+useful on its own — readable, greppable, browsable. Stop here if you
+don't need runtime recall.
+
+## 2. Export to the bridge JSON envelope
+
+```bash
+llmwiki export --target json --project-id my-kb
+```
+
+The export lands at `dist/exports/wiki.json`. `--project-id` is a
+**security boundary**: two projects supplying the same id collide in
+AtomicMemory because the bridge derives external IDs from it. Pick
+something stable and namespace it; treat it like a tenant key.
+
+The envelope schema is documented at
+[`packages/llmwiki/src/schema.ts`](../src/schema.ts); the regex pinning
+the on-wire `projectId` is
+`/^[a-z0-9][a-z0-9-]{0,62}$/`.
+
+## 3. Import into AtomicMemory
+
+```bash
+atomicmemory import --type llmwiki dist/exports/wiki.json \
+  --user "$USER" \
+  --namespace knowledge
+```
+
+What happens:
+
+- The CLI loads, validates, and size-checks the JSON file. Caps:
+  100,000 pages, 1 MB per page body, 64 KB per other field, 256 MB
+  total file size.
+- The active provider is checked for `verbatim` capability; the bridge
+  refuses to operate against text-only providers.
+- Each page becomes one verbatim memory record with `metadata.llmwiki.*`
+  carrying every advisory field from the export.
+- Re-running this command on the same project will **refuse** until you
+  pass `--allow-append-only --accept-duplicates`. AtomicMemory's
+  verbatim ingest is not idempotent by external ID; without the opt-in
+  flags, re-imports would silently double every page.
+
+### Dry run
+
+```bash
+atomicmemory import --type llmwiki dist/exports/wiki.json --user "$USER" --dry-run
+```
+
+Prints the page paths that would be imported. No memory writes occur.
+
+## 4. Query the runtime memory
+
+Once imported, the wiki content is queryable like any other AtomicMemory
+data:
+
+```bash
+atomicmemory search "chunking strategies" --user "$USER" --namespace knowledge
+atomicmemory package "what is retrieval" --user "$USER" --namespace knowledge
+```
+
+`atomicmemory package` returns an injection-ready `ContextPackage` you
+can hand directly to an LLM prompt.
+
+## Querying the export without import
+
+If you want to query the wiki directly through the SDK without ever
+ingesting into AtomicMemory, use the read-only `SnapshotLLMWikiProvider`:
+
+```ts
+import { loadLLMWikiExport, SnapshotLLMWikiProvider } from "@atomicmemory/llmwiki";
+
+const exportData = await loadLLMWikiExport("./wiki.json");
+const provider = new SnapshotLLMWikiProvider({
+  exportData,
+  scope: { user: "alice", namespace: "knowledge" },
+});
+
+const hits = await provider.search({ query: "chunking", scope: provider["scope"] });
+const pack = await provider.package({ query: "chunking", scope: provider["scope"] });
+```
+
+The provider is read-only by design; `ingest()` and `delete()` throw
+`E_LLMWIKI_PROVIDER_READONLY`. Use the import path above when you want a
+writable store.
+
+## When to use which path
+
+- **Compile + read the wiki**: lowest-overhead path; pure markdown.
+- **Compile + read + `SnapshotLLMWikiProvider`**: queryable knowledge without
+  a runtime store. Good for batch tasks, agents that consult one
+  project at a time, CI checks.
+- **Compile + import + AtomicMemory**: queryable runtime memory that
+  can also accept new memories from other sources. Good when the wiki
+  is a starting point and the agent learns more over time.

+# Threat Model — `@atomicmemory/llmwiki`
+
+This document consolidates the bridge's security claims so reviewers and integrators can audit the trust boundary in one place rather than reconstructing it from docstrings.
+
+## Assets
+
+What the bridge protects, in priority order:
+
+1. **AtomicMemory store integrity.** Every byte written via the bridge must be attributable to a legitimate `(user, projectId)` pair. An adversary writing records that *appear* to come from the bridge is the most damaging outcome.
+2. **`projectId` namespace.** Two different real projects must not share an external-ID prefix, or one of them silently amplifies records into the other's namespace (see "duplicate amplification" below).
+3. **Memory store availability.** A malicious export must not be able to consume unbounded memory or CPU on the importing process.
+
+## Attackers
+
+We model three:
+
+### A0 — Hostile wiki author (prompt injection into LLM context)
+
+The most important attack surface. Imported wiki bodies become memory records that downstream LLMs read back. A page that contains `<<<SYSTEM: ignore prior instructions...>>>` (or any other prompt-injection vector) lands directly in the consuming LLM's context window the next time `search()` retrieves it.
+
+**This is in scope precisely because the bridge has no content sanitization.** The defense is a trust marker:
+
+- Every imported memory carries `metadata.llmwiki.trustLevel = "external-import"`.
+- Every imported memory carries `metadata.llmwiki.version = 1` so downstream readers can branch on a known schema version.
+
+Downstream packaging code is *required* to read the trust marker and surface it to the LLM in a way the LLM can act on (e.g. wrapping the body in `<untrusted-source>` tags). The bridge cannot enforce this on the packaging layer; it can only stamp the signal.
+
+If you import a wiki you do not fully trust, you are extending operator-equivalent trust to every author of every page. Apply the same hygiene you would apply to any third-party content source.
+
+### A1 — Malicious exporter
+
+A compromised or malicious `llmwiki` instance produces an export file with hostile contents but a well-formed envelope shape. Defenses:
+
+- The JSON schema (`schema.ts`) enforces shape, per-field length, array length, citation start/end semantics, and `pageCount === pages.length`.
+- `nesting-guard.ts` enforces nesting depth AND a per-string size cap that applies to ALL string values reachable from the root — including unknown passthrough fields the schema accepts but doesn't type-check.
+- `projectId` and `slug` are validated against strict regexes both at schema time AND as a tripwire inside `buildExternalId`. Identifier injection (slugs containing `/`, `..`, control chars) is impossible without both layers being bypassed.
+
+### A2 — Malicious export-file supplier
+
+The export file came from a trusted exporter, but is handed to the importer by an untrusted third party (e.g. an attacker MITMs the file). The exporter's signature is NOT verified by v1; treat any export as if it came from A1.
+
+### A3 — Concurrent CLI user
+
+Two processes import the same `projectId` simultaneously. The probe → ingest sequence is not atomic. Each process may see "first import, proceed" and write parallel record streams.
+
+- **v1 mitigation:** documented assumption that the bridge is used serially. The CLI handler's docstring calls this out explicitly.
+- **Follow-up:** advisory lock keyed on `(user, projectId)` in AtomicMemory core.
+
+## Threat model defenses, by layer
+
+| Layer | What it stops |
+|-------|---------------|
+| Stream-bounded read | Files larger than `MAX_TOTAL_SIZE_BYTES`, files that grow between `stat` and `read` |
+| Raw-string depth prescan | Pathologically nested JSON before `JSON.parse` allocates |
+| `JSON.parse` | Malformed JSON |
+| Iterative depth + per-string cap walker | Surviving nesting-depth attacks; oversized strings in known OR passthrough fields |
+| Zod schema | Wrong shape, missing required fields, bad enum values, regex-invalid `slug`, bad citation ranges |
+| `validateProjectId` tripwire in `buildExternalId` | Identifier injection via projectId even when schema is bypassed |
+| `validateSlug` tripwire in `buildExternalId` | Identifier injection via slug even when schema is bypassed |
+| `assertSupportsVerbatim` capability gate | Silent text-mode re-extraction that would drop bridge metadata |
+| Re-import probe with provenance double-check | Forged `metadata.externalId` faking "already imported" state to DoS imports |
+| Fail-safe inconclusive outcome | Silent duplicate amplification when the probe runs out of budget |
+| `SnapshotLLMWikiProvider.assertScopeMatches` | Cross-user tenant leakage when one process serves multiple users |
+| Duplicate-slug detection at construction and ingest | Provider semantics drifting from ingest semantics (same `(dir, slug)` mapped to different content) |
+
+## Failure mode under projectId collision
+
+Under current AtomicMemory verbatim semantics — which are append-only by external ID — a `projectId` collision does NOT produce a silent overwrite. It produces **silent duplicate amplification**: two projects sharing a `projectId` write parallel record streams under the same external-ID prefix, polluting each other's namespace without either side noticing until a list/search returns records they didn't author.
+
+The boundary discipline matters regardless of failure mode; only the consequence differs.
+
+## Out of scope (v1)
+
+- **Provider-side bugs.** A buggy `MemoryProvider.ingest` implementation can drop or corrupt records after the bridge has handed them off. The bridge cannot defend against the layer below it.
+- **Network-layer attacks.** The bridge assumes the transport between CLI and provider is trustworthy. TLS, replay protection, etc. live at the provider's boundary, not here.
+- **Tokenizer correctness.** `package()` budgeting uses a coarse 4-chars/token heuristic by default. Callers needing accurate budgets pass `tokenize` via `SnapshotLLMWikiProviderOptions`. A misconfigured tokenizer can over- or under-fill a context window; the bridge doesn't verify token counts.
+- **Exporter-side signing.** The bridge has no way to verify that an export came from an authentic `llmwiki` instance. A signed-export feature is a v2 conversation.
+- **Multi-writer conflict resolution.** Two team members editing the same wiki page concurrently is a problem for `llmwiki`, not the bridge.
+
+## Known v1 limitations that affect this model
+
+These ship as documented limitations rather than fixes:
+
+- **Re-import detection is O(n).** Up to 50,000 memories walked per probe; above that the import is refused as inconclusive (fail-safe). A metadata-prefix list filter in the SDK would collapse this to one indexed call.
+- **No atomic transaction.** Ingest is one-page-per-call; a failure at page N leaves N-1 records committed. Per-page error collection (`partialFailures` in the result envelope) surfaces this honestly rather than masking it.
+- **No exporter signature.** See A2.
+- **Verbatim is contract-trust.** We check `capabilities().ingestModes.includes("verbatim")` but don't round-trip a record to verify the persisted shape carries a verbatim marker.
+

+# Running llmwiki + AtomicMemory as two MCP servers
+
+A common configuration is to give an agent both:
+
+- **llmwiki MCP**: read-only access to compiled, source-cited knowledge.
+- **AtomicMemory MCP**: read/write access to runtime, mutable memory.
+
+This split lets the agent ground answers in stable knowledge AND retain
+session-specific learnings. It also means the agent's tool surface is
+the union of both servers — that is the security question this guide
+exists to address.
+
+## Capability boundaries: enforce, do not request
+
+The agent prompt rule "promote stable runtime knowledge back to llmwiki
+only after review" is helpful, but it is governance by hope. Real
+isolation comes from configuring each MCP server with the minimum
+tool surface for its role.
+
+### llmwiki MCP
+
+`llmwiki serve` is read-only by default in v1 — it exposes
+`search_pages`, `get_page`, `get_context_pack`, and equivalents.
+There is no write surface to disable.
+
+### AtomicMemory MCP
+
+`@atomicmemory/mcp-server` exposes both read and write tools by
+default. When pairing it with llmwiki in the same agent session, you
+want write tools to be opt-in for the agent surface.
+
+> **Status note (2026-05).** The configuration sketch below assumes a
+> read-only flag on the AtomicMemory MCP server. That flag is
+> **forward-looking** — at the time of writing this guide, we have
+> not verified that `@atomicmemory/mcp-server` honors
+> `ATOMICMEMORY_MCP_READ_ONLY` (or an equivalent CLI flag). Treat the
+> snippet as the *intended* shape; before relying on it, confirm
+> against the version of `@atomicmemory/mcp-server` you have
+> installed. Until the flag is confirmed, the practical workaround is
+> to run two AtomicMemory profiles — one read-only for the agent's
+> MCP surface, one with full privileges for human-driven CLI usage —
+> and point the MCP server at the read-only profile.
+
+```jsonc
+// MCP config (forward-looking shape — verify against your installed version)
+{
+  "mcpServers": {
+    "llmwiki": {
+      "command": "llmwiki",
+      "args": ["serve", "--project", "./"]
+    },
+    "atomicmemory": {
+      "command": "atomicmemory-mcp",
+      "env": {
+        // Verify this is honored by your installed @atomicmemory/mcp-server.
+        "ATOMICMEMORY_MCP_READ_ONLY": "true"
+      }
+    }
+  }
+}
+```
+
+## Recommended agent rule
+
+Even with the capability-enforced boundary above, encode the
+direction of trust in the agent prompt:
+
+> Treat llmwiki content as authoritative reference material. Treat
+> AtomicMemory content as session-specific runtime state. Promote
+> stable runtime knowledge back to llmwiki only after human review.
+
+This makes the architectural intent legible to the agent without
+relying on it for enforcement.
+
+## Why not one MCP server with both surfaces
+
+A single combined MCP server would conflate the trust boundary: every
+tool would carry the same capabilities. The two-server split keeps
+"stable curated knowledge" and "mutable runtime memory" addressable as
+distinct surfaces — by the agent, by humans inspecting the config, and
+by future capability-gating logic.

+//     interacts with tsx's ESM transform in a way that strips named exports
+//     from TypeScript source files. Using the pre-built dist avoids the
+//     conflict while still exercising the real shipped artifact (which is
+//     why this test belongs in the dist-contract suite — and the shared
+//     before() build above guarantees the dist is fresh, race-free).
+//   - The script lives inside the package dir so `@atomicmemory/sdk` and
+//     relative dist paths resolve via the package's node_modules.
+//   - The deny hook (register-deny.mjs → deny-compiler.loader.mjs) uses

+ *
+ * **Memory profile.** This is a *bounded read with streaming size
+ * enforcement*, NOT a streaming parse. We stream bytes off disk and
+ * abort as soon as the accumulator exceeds `MAX_TOTAL_SIZE_BYTES`,
+ * but then `JSON.parse` materializes the full object graph in memory
+ * before any further processing. Peak memory is approximately
+ * 2× file size (raw string + parsed graph) plus chunk overhead. For
+ * a 256 MB ceiling, plan for ~700 MB peak. True streaming parse
+ * (e.g. via `stream-json`) is a v2 conversation.
+ *
+ * Layered defense, in order:
+ *
+ *   1. `createReadStream` accumulates bytes and aborts the read as soon
+ *      as `MAX_TOTAL_SIZE_BYTES` is exceeded — fail-safe against a
+ *      file that grows between `stat` and `readFile` (the previous
+ *      implementation's TOCTOU gap) and against pipes that don't have
+ *      a stable `stat`-able size at all.
+ *   2. A raw-string nesting prescan rejects pathologically nested input
+ *      BEFORE `JSON.parse` materializes the object graph — `JSON.parse`
+ *      would otherwise still allocate the whole tree even if the
+ *      post-parse depth guard would later reject it.
+ *   3. `JSON.parse` on the bounded buffer.
+ *   4. `assertNestingDepthSafe` walks the parsed document iteratively
+ *      as defense in depth against the prescan missing an edge case,
+ *      and ALSO enforces a per-string size cap so unknown passthrough
+ *      fields can't carry oversized payloads through the schema.
+ *   5. Zod schema validates the shape and enforces per-field caps.
+ *
+ * **Defense-in-depth cost.** The raw prescan (step 2) walks the raw
+ * string char-by-char and the post-parse walker (step 4) walks the
+ * parsed graph node-by-node. Both run on every load. For legitimate
+ * inputs near the 256 MB ceiling this adds seconds of CPU; for
+ * adversarial input the prescan aborts before parse so the post-walk
+ * never fires. We keep both because each catches what the other

+ *

+ *      fields survive forward-compat-style. Without this walker, a
+ *      hostile export could ship `evilField: "<200 MB string>"` and
+ *      pass shape validation. By capping every string value
+ *      reachable from the root (known or not), the size guarantee in
+ *      `limits.ts` holds for passthrough fields too. We use
+ *      `MAX_BODY_LENGTH` (1 MB) as the per-value ceiling — it's the
+ *      largest legitimate string in the contract (page body), so a

+ * Read-only MemoryProvider that serves a loaded llmwiki export.

+ * Lets SDK consumers query an llmwiki project directly without first
+ * importing into AtomicMemory. Useful when the wiki is the
+ * authoritative knowledge surface and a runtime memory store is
+ * overkill — the export itself becomes the queryable substrate.
+ *
+ * Scope and limits:
+ *
+ *   - **Single-tenant by construction.** The provider is constructed
+ *     for ONE scope. Every `search/list/get/package` call must pass a
+ *     `request.scope` whose `user` matches construction; otherwise the
+ *     call throws `E_LLMWIKI_PROVIDER_SCOPE_MISMATCH`. Returned
+ *     `Memory.scope` reflects the request scope, NOT the construction
+ *     scope, so a multi-tenant caller wiring a separate provider per
+ *     user still sees attribution that matches the caller. If you
+ *     truly need a multi-tenant provider, construct one per user.
+ *   - **Read-only**: `ingest`, `delete`, and every mutation extension
+ *     throw `LLMWikiBridgeError("E_LLMWIKI_PROVIDER_READONLY")` so
+ *     callers fail loudly instead of silently no-op'ing.
+ *   - **Lexical search**: case-insensitive substring match over
+ *     title + body + summary + tags. v1 deliberately skips embedding /
+ *     ranking work — full semantic search lives in the llmwiki CLI's
+ *     own `context` command, and shipping a second ranking pipeline
+ *     here would duplicate that effort.
+ *   - **Lossy `package()`**: returns a simple `ContextPackage`
+ *     concatenating matching page bodies with a budget-aware
+ *     truncation. The full `llmwiki context` pipeline (graph
+ *     expansion, citations, source windows) is NOT projected.

+- `mode: "verbatim"` with `content`: asks the provider to store exactly one deterministic record. This is intended for lifecycle records such as compact summaries. Providers that cannot guarantee verbatim semantics may reject it. Supply `contentClass` (`summary` | `redacted` | `raw`) describing what you are storing: a core with the default `RAW_CONTENT_POLICY=reject` refuses unstamped or `raw` verbatim content.
 
 Optional `metadata`, `provenance`, and `kind` are accepted. Deterministic AtomicMemory records store the provided `content` directly; provenance is persisted through `sourceSite` / `sourceUrl`. Caller-supplied `metadata` is forwarded to core's `/v1/memories/ingest/quick` route and persisted to the memory's `metadata` JSONB column (atomicmemory-core PR #51 + atomicmemory-sdk PR #15). It also continues to carry integration behavior such as `dedupe_key`, which the MCP layer reads to synthesize a deterministic `sourceUrl` when the caller omits `provenance.sourceUrl`. Reserved keys (`cmo_id`, `headline`, `memberMemoryIds`, etc. — full list in core's `RESERVED_METADATA_KEYS`) are rejected by core with 400.

+containing `/v1/`. Breaking changes get a new `v2/` directory, not an in-place
+edit.
+
+## 1. Date encoding (`FilterExpr.value`, and Date fields generally)
+
+`FieldFilter.value` is typed `string | number | boolean | Date | Array<...>`
+in-process. On the wire there is no `Date`:
+
+- A `Date` operand is encoded as an **ISO-8601 / RFC-3339 date-time string**
+  via `Date.prototype.toISOString()` (e.g. `"2026-05-30T12:00:00.000Z"`,
+  always UTC, millisecond precision, trailing `Z`).
+- The same rule applies to every Date-typed field that crosses the boundary:
+  `Memory.createdAt`, `Memory.updatedAt`, `TemporalSearch.asOf`
+  (serialized as `as_of`), `observed_at`. These appear as ISO-8601 strings in
+  JSON even though the SDK surfaces them as `Date` objects.
+- Numeric operands stay numbers; booleans stay booleans; string and
+  number arrays serialize as JSON arrays.
+
+Note: `SearchRequest.filter` is part of the contract but the AtomicMemory
+provider's `doSearch` does not yet forward `filter` to core. The encoding rule
+above is the contract any provider MUST honor once it wires filters; it is not
+a claim that AtomicMemory applies server-side filtering today.
+
+## 2. `list` cursor format
+
+The `cursor` returned by `list` (and the `ListResultPage.cursor` / extension
+`cursor`) is an **opaque, stringified non-negative integer offset**:
+
+- The provider derives it as `String(previousOffset + pageLength)` and reads it
+  back with `parseInt(cursor, 10)`.
+- A request with no `cursor` starts at offset `0`.
+- `cursor` is **absent** (undefined) on the last page — i.e. when fewer than
+  `limit` rows were returned there is no next page and no `cursor` field.
+- Treat the value as opaque: do not parse, increment, or otherwise interpret it
+  client-side. It is offset-based today; that is an implementation detail behind
+  the opaque-string contract.
+
+## 3. `Scope` field mapping
+
+The backend-agnostic `Scope` maps onto AtomicMemory core's wire fields as
+follows (see `scope-mapper.ts` and the provider request builders):
+
+| `Scope` field | Wire field | Notes |
+| --- | --- | --- |
+| `scope.user` | `user_id` | Required by AtomicMemory (`requiredScope.default = ['user']`). |
+| `scope.thread` | `session_id` | Emitted on ingest, search, and list only. Routes that do not filter by session (get/delete/expand) must not send or echo it. Returned `session_id` must round-trip the requested `thread`. |
+| `scope.namespace` | `namespace_scope` | Workspace/namespace partition for search and packaging. |
+| `scope.agent` | *(no direct core field)* | AtomicMemory does not project the generic `Scope.agent` onto a wire field on the core search/list/get path. Agent-scoped behavior is expressed through the AtomicMemory-specific `MemoryScope` workspace variant (`agent_id` / `agent_scope`), which is a separate, namespace-extension surface — not the generic `Scope.agent`. A generic `Scope.agent` value does not silently become `agent_id`. |
+
+## 4. `IngestResult.unchanged`
+
+`IngestResult.unchanged` is **always an empty array on the wire today**.
+
+Core's ingest responses report created and updated memory ids but do not emit a
+no-op/deduped set, so the provider populates `created` and `updated` from the
+backend and sets `unchanged` to `[]`. Consumers must not infer "nothing was a
+duplicate" from an empty `unchanged`; the field is reserved for a future
+backend capability and currently carries no signal.
+
+## 5. `score` vs `rankingScore` and cross-provider comparability
+
+`SearchResult` exposes several scalar scores. Their semantics:
+
+- **`score`** — the backward-compatible provider score. For AtomicMemory this
+  is the composite `rankingScore` and is **not normalized** (may fall outside
+  `[0, 1]`). Other providers preserve their own historical `score` meaning.
+  Because the definition is provider-specific, `score` is **not comparable
+  across providers** and must not be used for cross-provider thresholds.
+- **`similarity`** — raw semantic/vector similarity when the provider exposes
+  it. Higher is better. Provider-defined scale.
+- **`rankingScore`** — the composite ranking/debug score (RRF-style fusion in
+  AtomicMemory). Useful for debugging rank order; **not normalized**.
+- **`relevance`** — normalized injection relevance clamped to `[0, 1]`. This is
+  the field to use for threshold checks (`SearchRequest.threshold`) and the
+  only score with a portable, cross-provider-comparable meaning.
+
+Rule of thumb: filter and gate on **`relevance`**; surface `score` only for
+backward-compatible display; use `similarity` / `rankingScore` for debugging.
+
+## 6. Retrieval receipt
+
+The audit-grade retrieval receipt is **snake_case** on the wire, mirroring the
+AtomicMemory core search response (`/search` and `/search/fast`). It is the
+per-response object plus two per-result fields:
+
+- Per response (`SearchResultPage.retrieval`):
+  `embedding_provider`, `embedding_model`, `embedding_model_version`,
+  `embedding_dimensions`, `query_text`, `candidate_ids` (returned memory ids in
+  ranked order), `trace_id`.
+  - `embedding_model_version` is the resolved model id (no supported provider
+    exposes a separate immutable version string); it is never fabricated.
+  - `embedding_provider` is present on the core wire shape; the
+    cross-language required set is the six fields named in the schema's
+    `required` list (`embedding_model`, `embedding_model_version`,
+    `embedding_dimensions`, `query_text`, `candidate_ids`, `trace_id`).
+- Per result (`SearchResult`):
+  - `version_id` — the owning claim's `current_version_id`, letting a client
+    pin the exact retrieved version as a replay fixture. `null` when the memory
+    has no claim version (e.g. workspace-pool rows).
+  - `observed_at` — ISO-8601 date-time when the memory was observed/recorded.
+
+The receipt is always present on search responses; it is not gated on retrieval
+tracing. It exists so a retrieval can be logged and replayed bit-for-bit, which
+is what makes an audited path deterministic.

+# Changelog
+
+## 0.1.17
+- Version synchronized with the other atomicmemory-internal plugins (claude-code,
+  codex, cursor, hermes, openclaw all at 0.1.17). Future versions track that
+  shared plugin version rather than per-change bumps.
+- Fix Message-typed inputs being stringified as JSON. Search Context `query` and
+  Store Message `message`, when fed from another component's Message output,
+  arrived as Message objects whose `str()` is JSON (`{"text": ...}`) — corrupting
+  the search query / ingest content. Now extract `.text` (`coerce_text`). This
+  made flow-wired recall flaky/empty.
+
+## 0.1.3
+- Search Context now recalls **user-scoped** (across sessions) by default — the
+  point of long-term memory. Previously it scoped retrieval to the Langflow run
+  `session_id`, and since Core hard-filters search/list by session, "store in
+  session A, recall in session B" returned nothing. New advanced input
+  `Scope to session` (default off) restores session-only retrieval when wanted.
+  Store Message / Chat Memory session behavior is unchanged.
+
+## 0.1.2
+- Rename component display names to lead with the function (e.g. "Store Message
+  (AtomicMemory)") instead of "AtomicMemory …". Under the `atomicmemory` sidebar
+  category the old prefix was redundant and truncated to an indistinguishable
+  "AtomicMemory…" for all four. Internal `name`s are unchanged.
+
+## 0.1.1
+- Fix `langchain-core` dependency pin (`<1.0` → `<2.0`) so the package installs
+  alongside Langflow, whose `lfx` requires `langchain-core>=1.2.28`. Verified
+  running against `langchain-core` 1.4.0; our code only uses stable APIs.
+
+## 0.1.0
+- Initial release: AtomicMemory Chat Memory (read-only), Search Context,
+  Store Message, and Delete components for Langflow, backed by the
+  `atomicmemory` Python SDK.

+# AtomicMemory components for Langflow
+
+Four Langflow custom components backed by the Python `atomicmemory` SDK:
+
+They appear in the Langflow component sidebar under the **atomicmemory** category:
+
+| Component | Purpose |
+|-----------|---------|
+| **Chat Memory (AtomicMemory)** | Read-only chat history (Message History backend) from a user/session scope. |
+| **Search Context (AtomicMemory)** | Query-driven, prompt-ready memory context, **user-scoped across sessions** by default (packaged or search-only). |
+| **Store Message (AtomicMemory)** | Explicitly persist a message/turn into memory. |
+| **Delete Memories in Scope (AtomicMemory)** | Best-effort erasure of a scope's memories (confirm-gated). |
+
+## Requirements & compatibility
+
+- Python ≥ 3.10, `atomicmemory >= 1.0.1`, `langchain-core`.
+- **Langflow is the host** and must be installed in the same environment.
+  Tested with Langflow `>=1.6,<2.0` (the components import a few `lfx` internals;
+  see the loader smoke test). Newer Langflow majors may move these symbols.
+- A running **AtomicMemory Core** (default `http://localhost:17350`). Core needs
+  an LLM/embeddings key for ingest extraction.
+
+> **Heads up:** ingest runs synchronous LLM extraction + embedding, so storing a
+> memory can take **seconds (sometimes ~20s)**. Writes are explicit (Store Message)
+> so this latency is visible, not hidden. Chat Memory is **read-only** — it never
+> auto-writes on every turn. If the backend is unreachable, Chat Memory **fails
+> closed** (raises a clear error) by default; set its `Fail open on error` toggle
+> to return empty history instead.
+
+## Install
+
+```bash
+pip install atomicmemory-langflow            # into Langflow's environment
+# copy the component entry files into your Langflow components root:
+npx @atomicmemory/langflow-plugin --target ~/.langflow/components --python <langflow-python>
+# or set the components root via env instead of --target:
+LANGFLOW_COMPONENTS_PATH=~/.langflow/components npx @atomicmemory/langflow-plugin --python <langflow-python>
+```
+Restart Langflow; the components appear under the **atomicmemory** category.
+
+## Scope, identity & multi-tenant safety
+
+Memory is scoped by `user` (required) and optional `session` (thread).
+`User ID` defaults to the **Langflow run user** when blank; an explicit value
+overrides it. Note this is run context, not strong auth — in CLI/anonymous paths
+Langflow may auto-generate an opaque user id.
+
+**Search Context recalls user-scoped (across sessions) by default** — long-term
+memory should persist beyond a single conversation, and Core hard-filters
+search/list by session. Set its advanced `Scope to session` toggle to restrict
+retrieval to the current session. Chat Memory (this-conversation history) and
+Store Message remain session-aware.
+
+(`namespace` is not exposed in Phase 1: the AtomicMemory Python provider only
+applies it on search/package, not ingest/list/delete, so exposing it would
+silently break store/delete scoping. It returns once the SDK honors it end-to-end.)
+
+**Trust boundary:** scope is the only memory boundary, and Langflow lets `user_id`/
+`session_id` be set via flow inputs/tweaks. In shared / multi-tenant / Cloud
+deployments, control who can edit and run flows — a flow author who sets `user_id`
+can read/write that user's memories.
+
+## Security
+
+- Put API keys only in the **API Key** (secret) field — never in **Provider Config**
+  (it is stored in plaintext in the flow). **Provider Config is allowlist-only**:
+  only known tuning keys (`timeoutSeconds`, `apiVersion`) are accepted; everything
+  else — URLs, keys, and any secret-shaped key (`accessToken`, `clientSecret`, …) —
+  is rejected.
+- **`provider` is validated**: Phase 1 accepts only `atomicmemory`, even via API/tweaks
+  (the UI dropdown is not the only guard).
+- **`API URL` is fail-closed for remote hosts.** It must be `http(s)` and resolve to a
+  local host by default; pointing memory at a non-local endpoint requires the
+  **operator** (not the flow author) to opt in via `ATOMICMEMORY_LANGFLOW_ALLOW_REMOTE=1`
+  or `ATOMICMEMORY_LANGFLOW_ALLOWED_HOSTS=host1,host2`. **This is not full SSRF
+  protection:** it does not sandbox the loopback interface, so a flow author can still
+  reach services bound to the Langflow host's `localhost`/`127.0.0.1` (any port). Treat
+  flow authors as trusted, or add network-egress controls, on shared/multi-tenant/cloud
+  deployments.
+- Retrieved memory is emitted as ordinary context, never as a system message.
+
+## Provider neutrality
+
+`provider` defaults to `atomicmemory` (the only Phase 1 tested provider). The
+architecture is provider-neutral — provider name + `provider_config` flow to the
+SDK — but other providers are not yet listed in the dropdown.
+
+## Testing & known follow-ups
+
+Unit tests run without a live backend (`cd plugins/langflow && python -m unittest
+discover -s tests`); the SDK-contract and Langflow-loader tests exercise the real
+`atomicmemory` SDK models and `lfx` template builder when those packages are
+installed.
+
+Follow-ups (tracked, not yet in this PR):
+- **End-to-end lane against a real AtomicMemory Core** (Docker + Core + an LLM key):
+  Store Message → Search Context → Delete with synthetic data, with the package
+  installed into a Langflow-compatible venv. Unit tests use fakes/model coercion;
+  this lane would catch integration drift the fakes can't.
+- **Namespace scoping** once the Python SDK honors it on ingest/list/delete (today
+  only search/package), at which point the `namespace` input returns.
+- **Branded AtomicMemory icon** (vendor logo, like the model providers') — **deferred**.
+  Each component currently uses a distinct Lucide icon (`save` / `search` /
+  `messages-square` / `trash`). A real brand mark is a Langflow *vendor icon*, which
+  per Langflow's docs requires frontend changes (an `@/icons/AtomicMemory` SVG +
+  forwardRef wrapper + a `lazyIconImports` entry) and so cannot ship from a Python
+  component bundle — it needs an upstream Langflow PR. Logo SVGs exist under
+  `supermem-internal-web/static/img/`.

+# AtomicMemory × Langflow examples
+
+Three importable flows, built and verified against a live AtomicMemory Core:
+
+| File | What it shows |
+|------|---------------|
+| `atomicmemory_cross_session_demo.json` | **Minimal** cross-session memory (no LLM key needed). |
+| `memory_chatbot_atomicmemory.json` | Langflow's **Memory Chatbot**, leveled up: session-local memory → durable **cross-session** memory. |
+| `vector_store_rag_atomicmemory.json` | Langflow's **Vector Store RAG**, personalized: doc retrieval **+** cross-session memory of the user. |
+
+All three put secrets via the field/`tweaks` (never the JSON), use Search Context
+**user-scoped** (recall across sessions) in search mode, and force Store Message onto
+the output path so writes always run.
+
+---
+
+# 1. Minimal cross-session memory demo (`atomicmemory_cross_session_demo.json`)
+
+A minimal, **retrieval-grounded** flow that proves AtomicMemory gives a Langflow
+assistant durable memory **across separate sessions** — with explicit, visible
+writes and no hidden auto-ingest. No LLM key required: the Chat Output shows the
+recalled memory directly. Verified end-to-end (Run 1 stores in session A, Run 2
+recalls in session B).
+
+## Flow shape (4 nodes)
+
+```
+Chat Input → AtomicMemory Store Message → AtomicMemory Search Context → Chat Output
+```
+
+- **Store Message** persists the user message (explicit write). It sits on the path to
+  the output, so it always runs; its output feeds the next node.
+- **Search Context** recalls **user-scoped** long-term memory (across sessions —
+  `Scope to session` is off) in **search mode** (`Use packaged context` off, which is
+  less threshold-sensitive for varied queries), and emits prompt-ready text.
+- **Chat Output** shows the recalled context.
+
+Both AtomicMemory nodes use `User ID = demo-dana` and `API URL = http://localhost:17350`.
+
+## Prerequisites
+
+- A running **AtomicMemory Core** at `http://localhost:17350` (needs an LLM/embeddings
+  key for ingest extraction). Confirm: `curl -H "Authorization: Bearer <CORE_API_KEY>" http://localhost:17350/v1/memories/health`.
+- **Langflow** with the AtomicMemory plugin (≥ 0.1.17) installed in its Python env
+  (see `../README.md`).
+
+## Secrets are NOT in this file
+
+The **API Key** field is intentionally blank (it's a `SecretStrInput`; Langflow loads
+secrets from its store, not the flow JSON). Supply your Core key (`local-dev-key` for
+local dev) at run time:
+- **UI:** open each AtomicMemory node and paste the key into **API Key**.
+- **API:** pass it via `tweaks`, e.g.
+  `tweaks: {"<StoreNodeId>": {"api_key": "local-dev-key"}, "<SearchNodeId>": {"api_key": "local-dev-key"}}`.
+
+## Run it
+
+Import via Langflow → **Settings → Import** → select the JSON, then set the API Key.
+
+- **Run 1** (session A) — store durable context:
+  > I'm Dana from Northstar Robotics. We use Langflow for internal support triage. I prefer concise technical answers, avoid Slack unless urgent, and our current priority is reducing agent latency.
+
+  The Store Message node reports the ingest outcome; ingest is slow (Core extracts + embeds — seconds).
+
+- **Run 2** (a **new session** B, same `demo-dana`) — recall:
+  > Given what you know about me and my current priorities, help me plan the next implementation step.
+
+  Chat Output returns the recalled facts — e.g. *"Dana's top priority is reducing agent
+  latency. Dana prefers concise answers. User's name is Dana."* — even though it's a
+  different session. That's cross-session memory.
+
+## Notes
+
+- **Search query phrasing matters.** The Search query references the user's context, so
+  it retrieves the stored facts. A generic query (e.g. "plan the next step") may return
+  nothing — semantic relevance, not a bug.
+- **Extraction is non-deterministic.** Occasionally a turn extracts 0 facts; re-run Run 1
+  with a fact-dense message and confirm with `GET /v1/memories/list?user_id=demo-dana`.
+- To make this **model-backed** (an assistant answer instead of raw context), insert a
+  Prompt + a chat-model component between Search Context and Chat Output, wiring the
+  Search context as `{memory_context}` and the Chat Input as `{user_message}`. (That's
+  exactly the next example.)
+
+---
+
+# 2. Memory Chatbot, leveled up (`memory_chatbot_atomicmemory.json`)
+
+Langflow's **Memory Chatbot** starter uses the built-in `Memory` component — chat history
+scoped to the *current* session, forgotten when the session changes. This version swaps
+that for **AtomicMemory**, giving the bot **durable, cross-session, semantic** memory.
+
+```
+Chat Input ─┬─▶ Store Message ─▶ Search Context ─▶ Prompt.{memory}
+            └────────────────────────────────────▶ Anthropic Model ─▶ Chat Output
+                                       Prompt ─────▶ Anthropic Model
+```
+
+**Verified end-to-end** with an Anthropic model:
+- Run 1 (session A): *"I'm Dana from Northstar Robotics; my priority is reducing agent latency; I prefer concise answers."*
+- Run 2 (**new session** B): *"What's my current priority?"* → the bot answers *"Your current
+  priority is reducing agent latency"* (and stays concise) — recalled across sessions.
+
+Setup on import:
+- **Model:** the `Anthropic Model` node references the `ANTHROPIC_API_KEY` Langflow global
+  variable. Set that variable (Settings → Global Variables) or paste a key / swap in your
+  preferred model component.
+- **AtomicMemory:** set the **API Key** on the Store/Search nodes (or via `tweaks`), and a
+  running Core at `http://localhost:17350`.
+
+# 3. Personalized RAG (`vector_store_rag_atomicmemory.json`)
+
+Langflow's **Vector Store RAG** starter answers from your documents. This version adds
+**AtomicMemory** so the assistant *also* remembers the **user** across sessions — the Prompt
+receives both the retrieved document `{context}` **and** the user's long-term `{memory}`:
+
+```
+File → Split → Knowledge Ingestion → Knowledge Base ─▶ parser ─▶ Prompt.{context}
+Chat Input ─▶ Knowledge Base.search                              Prompt.{question}
+Chat Input ─▶ Store Message ─▶ Search Context ─────────────────▶ Prompt.{memory}
+Prompt ─▶ Anthropic Model ─▶ Chat Output
+```
+
+The AtomicMemory personalization is wired and verified (Store → Search → `Prompt.memory`,
+same mechanism as #2). To run the **document** side you must supply your own documents and
+populate the Knowledge Base — exactly as the original Vector Store RAG starter requires
+(point the `File` node at your docs and run ingestion first). Model + AtomicMemory setup is
+the same as #2 (`rag-dana` is the demo user).

No LLM key needed \u2014 the Chat Output shows the recalled memory directly.\n\n## How it works\nYour message enters at **Chat Input**. **Store Message** writes it into AtomicMemory as an explicit, visible memory. **Search Context** then recalls the memory AtomicMemory holds for this user and passes it to **Chat Output**.\n\n## What AtomicMemory adds\nA normal flow forgets everything the moment a chat session ends. AtomicMemory gives it **durable memory that persists across separate sessions**, recalled **user-scoped** (by the person, not by one conversation) \u2014 so a fact stored today comes back in a brand-new chat tomorrow.\n\n## How to run it\n1. Run AtomicMemory Core at `http://localhost:17350`.\n2. On **Store Message** and **Search Context**, set the **API Key** (local dev: `local-dev-key`) and keep **User ID** as `demo-dana`.\n3. In the Playground, send: *\"I'm Dana; my priority is reducing agent latency; I prefer concise answers.\"*\n4. Start a **new session**, then ask: *\"What are my priorities?\"* \u2014 the stored facts come back, even in a different session.\n\n_Secrets are never written to this file \u2014 set the API Key after importing._",

That recalled memory fills the **Prompt**'s `{memory}` slot, and the **Anthropic** model answers the user's message using it. The reply goes to **Chat Output**.\n\n## How AtomicMemory levels it up\nThe starter's built-in **Memory** component only remembers the **current chat session** \u2014 open a new conversation and the bot has forgotten you. AtomicMemory replaces it with **durable, cross-session, semantic** memory, so the bot still knows who you are and what you care about in a brand-new session.\n\n## How to run it\n1. Run AtomicMemory Core at `http://localhost:17350`; set the **API Key** on Store/Search (local dev: `local-dev-key`) and **User ID** to `demo-dana`.\n2. **Model:** the **Anthropic** node reads the `ANTHROPIC_API_KEY` global variable (Settings \u2192 Global Variables), or swap in your own model.\n3. In the Playground, send: *\"I'm Dana; my priority is reducing agent latency; I prefer concise answers.\"*\n4. Start a **new session**, then ask: *\"What's my priority?\"* \u2014 the bot answers from memory recalled across sessions.",

You run this once.\n\n**Answering** (the top row) handles each question. The **Chat Input** fans out three ways: the **Knowledge Base** retrieves the document chunks that match the question (tidied up by **Parser**); **Store Message** saves the turn while **Search Context** recalls what AtomicMemory knows about the user; and the raw question. The **Prompt** combines all three \u2014 document context, user memory, and the question \u2014 and the **Anthropic** model writes the answer to **Chat Output**.\n\n## How AtomicMemory levels it up\nPlain RAG answers from your documents but treats every user as a stranger \u2014 it has no memory of who's asking. AtomicMemory adds a **cross-session memory of the user** alongside document retrieval, so each answer is grounded in your documents **and** personalized to the person.\n\n## How to run it\n1. On **Knowledge Base** and **Knowledge Ingestion**, set **Knowledge** to the **same** name on both.\n2. On **File**, select your document(s). On **Store Message** / **Search Context**, set the **API Key** (local dev: `local-dev-key`) and **User ID** to `rag-dana`. The **Anthropic** node uses the `ANTHROPIC_API_KEY` global variable.\n3. Run the **ingestion** row once to populate the Knowledge Base.\n4. In the Playground, tell it something durable about yourself. Then start a **new session** and ask about your documents in a way that also leans on what it knows about you \u2014 the answer combines retrieved documents with recalled user memory.\n\n\u26a0\ufe0f If the two **Knowledge** dropdowns don't match, ingestion fills one store while retrieval reads an empty one.",

+# Git hooks
+
+Committed git hooks for the AtomicMemory monorepo. They are installed into the
+clone's active hooks directory by `scripts/git-hooks/install-hooks.mjs`, which
+runs as the root `prepare` script on `pnpm install`. No hook-manager dependency
+is used.
+
+## Hooks
+
+- **`pre-push`** — blocks `git push` whose destination is the public mirror
+  `atomicstrata/atomicmemory`. The public repo is a read-only release surface:
+  it is updated only by the internal `public:sync` tooling (which opens a
+  sanitized public PR) and realigned by the public repo's `sync-to-private.yml`
+  workflow. Develop in `atomicmemory-internal` and publish through the tooling —
+  never push to public directly, including via a dev clone's `upstream` remote.
+
+  Policy lives in `scripts/guards/guard-public-push.mjs` (pure, unit-tested
+  under `scripts/guards/__tests__/`). The hook is a thin shim that forwards
+  git's `<remote-name> <remote-url>` arguments to that guard.
+
+## Override
+
+The publish tooling sets `ALLOW_PUBLIC_ATOMICMEMORY_PUSH=1` so its own,
+reviewed push to the public repo is not blocked. A human can use the same
+override in the rare case a direct public push is genuinely correct:
+
+```bash
+ALLOW_PUBLIC_ATOMICMEMORY_PUSH=1 git push ...
+```
+
+## Notes
+
+- The installer is worktree-correct: it resolves the shared common hooks dir via
+  `git rev-parse --git-path hooks`, so linked worktrees are covered too.
+- It never overwrites a pre-existing hook it did not author (it checks for a
+  marker string first).
+- It only activates in clones where `pnpm install` has run. A read-only public
+  mirror clone where deps are never installed should rely on a locally
+  installed hook instead; see the internal ops release-process docs.
+- The hook lives in the shared common hooks dir, so it also runs from a checkout
+  that predates the guard (a branch cut before it landed). When the guard script
+  is absent there, the hook is a no-op instead of bricking every push from that
+  checkout — there is nothing to enforce, and the guard is an accidental-push
+  guard, not a security boundary.
+
+See the internal ops release-process documentation for the full
+internal → public release flow.
