Review of this PR's own diff against feat/eql-v4-bindings. The core encoding is right: each scalar wrapper seals exactly the [tag] ++ payload leaf that vitaminc-aead-value 0.5.1 seals for the same value (I checked tags.rs/tagged.rs), each opens only its own tag and width, refusals carry kinds and never values, and the generated v4 files and eql_gen.go match a fresh eql-codegen bindings / go-eql run. The encryption test crate, clippy -D warnings, eql-codegen tests, and the new PostgreSQL test (run locally against a fresh eql_v4 install on Postgres 17) all pass. Two things need fixing before merge: the branch is red, and the equality terms are tied to a PRF domain that vitaminc is moving away from.
1. Blocker: stale assertions fail CI in two jobs, so the PostgreSQL and Go tests never run
packages/eql/crates/eql-bindings/src/encryption/targets.rs:613-620:a_producible_type_without_a_query_twin_answers_no_querystill treatsTextas unproducible. It assertsno_query(target("Text")).is_none()andrefuse_query("Text")isUnproducible.Textis producible now, so both are wrong.packages/eql/crates/eql-bindings/src/encryption/targets.rs:627:refusals_name_the_type_and_its_reasonexpects theTextOrdOrereason to contain"CLLW". This PR rewrote that reason.languages/golang/encrypt/guest/src/targets.rs:182andlanguages/golang/encrypt/guest/tests/native_ops.rs:1369still assertproducible == ["TextEq"].
cargo test --locked -p eql-bindings --all-features reproduces the first two locally (111 passed, 2 failed). In CI they fail "Rust workspace crates", at its mise run test:encryption step, and "WASI check, guests and Go (Linux)".
These failures matter beyond the red check:
test:encryption:postgresruns aftertest:encryptionintest-eql.yml, so CI never ran the newpostgres_stores_and_queries_every_producible_v4_type.- The guest failure skips "Go binding" and "Go live tests", so no Go test has run against the new types. The PR description says Go tests pass with rebuilt guests; the guest's own tests do not.
Suggested fix:
- At line 613, assert that
no_query(target("Text"))isSome(NoQuery { name: "Text" })and thatrefuse_query("Text")isNoQuery. - For the "an unproducible type is refused as that" case, use a type that is still unproducible and has no query twin (
Date,Json). - At line 627, match on
"ordering terms". - In the two guest tests, update the producible list to the nine types.
2. Major: IntegerEq / BigintEq terms use vitaminc 0.5's per-width PRF domains, which the target design replaces
prf_by_inner! (plaintext.rs:123-144) derives the term through i32::prf_visit_with_context / i64::prf_visit_with_context. Those use the legacy primitive domains vitaminc/prf/encoding/i32-le/v1 and i64-le/v1. On vitaminc main, cipherstash/vitaminc#380 (merged, not yet released) adds value-derived equality domains: every integer kind shares one domain, vitaminc/prf/value/integer-orderable/v1, and "legacy primitive PrfValue encodings retain their existing domains" (packages/prf/src/value.rs). ADR-0002 then has dynamic::term take &Value.
When Stack Encrypt moves to vitaminc 0.6, one of two things happens:
IntegerEqkeeps the legacy domain (prf_by_inner!as written does this). A Goint32field withindex=equalitythen derives the value-domain term, and it no longer matchesIntegerEq'shm. The guarantee inplaintext.rs:13-15,124,README.md:123-124andv4_types.rs:101-109breaks with nothing to flag it.IntegerEqmoves to the value domain. Then everyhmthe Go alpha stored under this release stops matching queries.=returns no rows rather than an error.
equal_values_of_different_widths_have_different_terms (v4_types.rs:156-166) also pins the opposite of the upstream design, where 42 as int32 and as int64 share a term.
Since the stated purpose is an alpha for a Go partner, data will be stored under these terms. Suggested fix, either:
- (a) ship only the storage-only types now (
Integer,Bigint,Text,Boolean,Real,Double). Their ciphertexts use the frozen leaf tags and are unaffected. KeepIntegerEq/BigintEqback until the 0.6 domains are released. - (b) keep them, but say plainly in the README, the changeset and the plaintext module docs that
hmterms from this release use vitaminc 0.5's domains and must be re-derived on the 0.6 upgrade. Drop or reword the width test so it does not pin a property the design removes.
3. Minor: the Go side has no guidance on integer and float widths, and one Go doc is now stale
languages/golang/cmd/stashgen/README.md:152still says "The engine producesTextEqtoday;encrypt_intowith any other type is refused".- This PR is the first where width matters, and the generator does not explain it:
kindOfWire(languages/golang/stashgen/engine.go:244) foldsInt32andInt64intoKindInt, andFloat32/Float64intoKindFloat. A field such asAge inttaggedstash:"age,encrypt_into=IntegerEq", or afloat64field taggedReal, passes stashgen's own kind check atengine.go:161.- The engine's plan check then refuses it, but with the generic engine message, not the "X seals a Y" one.
int8/int16are emitted asgensupport.Int32(emit.gokindExpr), so today they are accepted intoIntegerEq. ADR-0002 gives them their own kinds before the Go SDK ships, and then those declarations will start being refused.
Suggested fix: list the producible types in the stashgen README with the Go type each needs: int32 for Integer/IntegerEq, int64 for Bigint/BigintEq, float32 for Real, float64 for Double, bool for Boolean. Compare wire kinds rather than Kind in stashgen's local check. A follow-up PR is fine for the check. The README line is direct drift from this PR.
4. Minor: test gaps behind the "open each other" claim and the generated dispatch
v4_types.rschecks only one direction: a typed write opens as the value enum (as_value_enum). Nothing seals a leaf throughFfiValue(what a plain Go field writes) and opens it throughInt32/Int64/Bool/Float32/Float64::decrypt. That is the directionLeafVisitor/BoolVisitorimplement. I confirmed by reading vitaminc-aead-value 0.5.1 that the bytes agree, so this is a coverage gap, not a bug.- Of the nine generated encrypt/decrypt arms, only
IntegerEqandTextgo throughtargets::encrypt/decrypt.BigintEq's query arm (BigintEqQueryvs the storedhm) is never compared outside PostgreSQL.Float64is never checked against the value enum.RealandBigintare inserted into PostgreSQL but never read back. - A table-driven test over every producible row, through both
targets::encrypt/decryptandtargets::query, would cover each arm and catch a swapped type/plaintext pairing in the generator.
5. Nit
packages/eql/crates/eql-bindings/README.md:184: the "Proven" interoperability row still cites only tests/encryption/tests/text_eq.rs. Add v4_types.rs now that it covers the other types.

Review attestation: automated /code-review medium plus /cross-check-review-findings on head 8f6ec203.
Critical/blocking: none.
Should fix (confirmed against the code):
stashgenchecks only the coarse kind, soint64+Integerandfloat64+Realpass generation, contradicting the README (inline).eql-bindings/src/encryption/plaintext.rshas no tests for the hand-rolled tagged-leaf encoding (inline).
Minor / plausible, not blocking:
- Float
PartialEqis IEEE, so tests of the documented bit-pattern round trip can't use==.Copyplaintext scalars also can't be zeroized. - For unproducible types that now carry
plaintext: Some(...)(IntegerEq,IntegerOrd*,BigintEq, …), the width/kind error fires before the "held back until vitaminc 0.6" reason. eql_test.gopins the producible list by exact catalog order, so the Go test and two Rust tests must be edited together.- The changeset names only
@cipherstash/eql.stashgenbehaviour changes too, but Go has no release process yet.

Code review (medium). Two inline findings above, plus one on a file outside this diff:
languages/golang/stashgen/enginetest/enginetest.go:22,49(not changed by this PR): theStaticstub still lists onlyTextEqas producible and its refusal says "it produces TextEq". The real engine now produces seven types, so a stashgen test usingencrypt_into=Integer(orText,Bigint,Boolean,Real,Double) passes against the real engine but is refused by the stub. Worth updating alongside this PR.
No correctness bugs found in the target dispatch or codegen reasons. Nothing was built or run.

…text types A Go partner needs a pre-release of EQL v4 with Stack Encrypt before vitaminc 0.6 settles ordering. These are the v4 types that need no ordering term and whose value kind is already in vitaminc 0.5's value enum: Text, Integer, IntegerEq, Bigint, BigintEq, Boolean, Real and Double, beside TextEq. vitaminc 0.5 implements Encrypt for String but not for i32, i64, bool or the floats, and stack-encrypt deliberately has no combinator that re-encodes a plaintext. So eql_bindings::encryption::plaintext adds Int32, Int64, Bool, Float32 and Float64: each seals vitaminc's tagged leaf, the bytes FfiValue seals for the same value, opens only its own tag, and the integers derive the equality term of the integer inside. A value written through these types and one the Go SDK writes as a plain field open each other, and IntegerEq's term is a plain i32's. The derive reasons now have one source, encryption_gap: ordering terms wait for vitaminc-ore, float equality for vitaminc 0.6's canonical float, smallint/date/timestamp/numeric for their value kinds. Json stays unproducible: a JSON value seals as a tree of leaves and EQL's c holds one, and how a document becomes one leaf is a wire decision not made here. The encryption test crate checks each type through both entry points, against the value enum's leaf and the plain integer's term, and in PostgreSQL on an eql_v4 install: equality queries on IntegerEq and BigintEq return the right rows and every stored value opens. Refs #1130, #1133
Text became producible in this PR, so it is now the live storage-only type the no-query rule describes, and TextOrdOre's refusal names vitaminc-ore rather than CLLW. Both unit tests still asserted the old table and failed under --all-features.
Their equality terms came from vitaminc 0.5's per-width PRF domains (i32-le/v1, i64-le/v1). vitaminc main replaces those with one integer-orderable/v1 domain for every width, so shipping them now would either break the promise that IntegerEq matches a Go int32 equality field or leave every stored hm unmatchable after the upgrade. Both leave ENCRYPTION_DOMAINS with a reason that names the domain, the generated dispatch and the Go table mark them unproducible, and the PRF impls on Int32 and Int64 are removed so nothing derives a term under the old domains. The storage-only types, TextEq and the plaintexts stay. v4_types.rs now covers what the review found missing: a leaf the value enum sealed opens as each typed plaintext, every producible row goes through all three by-name entry points (a swapped type or plaintext in the generator fails), Float64 is checked against the value enum, and the Postgres test reads every column back. The width test that pinned the per-width design is gone. The guest's producibility assertions and the eql-bindings unit tests use the final producible set, and the stashgen README lists each producible type with the Go field type it takes.

Unit tests pin each leaf's tag, width and little-endian order through the same reader Decrypt uses, and refuse another tag or width. - The generated plaintext doc line shows without the stack-encrypt feature again; only its link to crate::encryption is feature-gated. - stashgen refuses a field of the right kind and the wrong width (int64 into Integer, float64 into Real) itself, naming both widths, as its README says. - enginetest.Static lists the seven types the engine produces, with their widths. - The eql-bindings README no longer says TextEq is the only producible type.

Summary
This makes Stack Encrypt produce every EQL v4 type that needs no ordering term and whose value kind vitaminc 0.5 already has:
Text,Integer,IntegerEq,Bigint,BigintEq,Boolean,RealandDouble, besideTextEq. It is what a Go co-development partner needs for an alpha before vitaminc 0.6 settles ordering.Changes
eql_bindings::encryption::plaintext:Int32,Int64,Bool,Float32,Float64. vitaminc 0.5 implementsEncryptforStringbut not for the scalar types, and stack-encrypt deliberately has no combinator that re-encodes a plaintext. Each wrapper seals vitaminc's tagged leaf (the bytesFfiValueseals for the same value), opens only its own tag, and the integers derive the equality term of the integer inside.Plaintextimpls for each, refusing a value of another kind rather than converting it.ENCRYPTION_DOMAINSlists the new domains, each family names its plaintext type, and every "not producible" reason now comes from one function. The reasons: ordering waits for vitaminc-ore, float equality for vitaminc 0.6's canonical float, smallint/date/timestamp/numeric for their value kinds.Jsonstays unproducible. A JSON value seals as a tree of encrypted leaves, and EQL'scfield holds one. How a document becomes one sealed leaf is a storage-format decision this PR does not make.Verification
