Reviewed at 2443429 against feat/eql-v4-ordered-ope-types (82ab168). No prior review comments on this PR.
Nothing blocking. The leaf parity, range checks and wiping all hold up under the code and the vitaminc 0.6.0 source; the findings are documentation precision. Ranked, most important first:
- Low: "That covers every copy this crate and Stack Encrypt make" overstates what is wiped (
plaintext.rs:28). The scalar handed to the sink is aCopyIntinside aCopyPhysical, andTimestamp::count()materialises ani128on the stack; none of those are wiped. That is exactly what vitaminc's ownNaiveDate,DateTime<Utc>andi64sources do, so it is not a regression, but a reader auditing wiping will take the sentence literally. Inline comment has a suggested wording. - Low: vitaminc-aead 0.6.0 already ships a wipeable
Timestamp(vitaminc_aead::Timestamp:Zeroize+ZeroizeOnDrop, redactedDebug, refuses the leap second at build,FromScalar, same nanosecond leaf). The module doc says the ecosystem offers nothing that can be wiped. The reason not to reuse it is real, I checked:EncryptFrom<S>forStackCipherTextandEqualityTermneedsS: Encrypt + Clone(packages/stack-encrypt/src/target/operations.rs:881,896) and vitaminc's type is deliberately notClone, and its only constructor takes aDateTime<Utc>. Worth one sentence in the module doc so the next reader does not file "why are there two". - Low: docs.rs will not render the
chrono/rust_decimalconversions.[package.metadata.docs.rs] features = ["targets"]does not turn those features on, soFrom<NaiveDate> for Dateand friends are invisible on docs.rs. Add them to the list (orall-features = true). - Nit:
RangeError::LeapSecondfrom the raw constructor.Timestamp::new(secs, 1_234_567_890)from a caller who mixed up units is just an invalid nanosecond field, but the error says "a leap second has no encoding". Fine for the chrono path; slightly misleading for the plain API. - Informational: the six new types have no frozen row fixture yet.
v4_ledger_rows.jsonis regenerable (EQL_UPDATE_FIXTURES=1), and the fixtures README says a frozen copy will be cut later. That matches how #1266 handled the ordered types, so not a blocker, but until it is cut a leaf-encoding change to these three kinds would be regenerated away rather than caught. If there is no issue tracking the cut, it may be worth one.
On the review-notes questions, with what the code says:
- Q1 (date epoch). vitaminc 0.6.0 counts from 1970-01-01:
kinds::chrono::date_daysisnum_days_from_ce() - 719_163,MIN_DATE_DAYS/MAX_DATE_DAYSare pinned toNaiveDate::MIN/MAXon that basis, andLogical::Dateadmits that count. The PR follows the engine; the ADR-0002 leaf table is what is stale. - Q4 (microsecond truncation). Confirmed engine-side behaviour, not this PR's. One consequence worth recording wherever it ends up: a client holding nanoseconds (chrono, Go
time.Time) derives a term for.1234567that matches a stored.123456, while PostgreSQL parsing the same text as a plaintexttimestampwould round it to.123457. The storage-only and ciphertext paths are unaffected.
What I verified as sound:
- Leaf parity.
Datevisits(Logical::Date, Int::I32(days)),Timestampvisits(Logical::Timestamp(Nanos), Int::I128(secs*10^9+nanos)),Decimalvisits(Logical::Decimal{scale}, Int::I128(mantissa)). Those are byte-for-byte the scalars vitaminc'sNaiveDate,DateTime<Utc>(viaconv::timestamp_nanos) andrust_decimal::Decimal(viadecimal::parts) sources emit. The unit tests assertscalar(&ours) == scalar(theirs)atNaiveDate::MIN/MAX,NaiveDateTime::MIN/MAX, pre-1970 instants,2^96-1, and rust_decimal's negative zero; the encryption suite asserts the storedcopens to the same frame as a chrono/rust_decimal-sealed value, and the Go-sealed ledger rows open in Rust with thehmquery bytes equal in both languages. Scale is kept in the leaf (1.5and1.50differ inc, agree inhm), which is what rust_decimal produces and what the docs say. - Range checks.
admits/timestamp_nanosare inclusive at both ends; tests cover each edge and one past it, plus thei32/i64/i128extremes andu8::MAXscale.i64::MIN * 10^9fits ani128. The twoFromimpls that skip the check (From<NaiveDate>,From<rust_decimal::Decimal>) cannot produce an out-of-range value: vitaminc's own test pinsMIN/MAX_DATE_DAYSto chrono's constants, and rust_decimal's representation is a 96-bit mantissa with scale at most 28, which are the same boundsdecimal_in_rangeapplies. "Only a leap second is refused" holds becauseDateTime<Utc>'s range isNaiveDateTime's, whichMIN/MAX_TIMESTAMP_NANOSare pinned to. - Error messages.
RangeErroris a fieldless enum, so neitherDebugnorDisplaycan carry the value. - Zeroization. Fields are private, both constructors return an owned value,
Cloneyields an owned value with the sameDrop, the ownedEncryptvisits through&Selfand is then dropped,from_framebuilds throughFromScalarinto the owning type andrun_targetholds it inZeroizing,into_frameconsumes it. No serde on the plaintexts. Thewiped!macro callszeroize()on each field explicitly (thezeroizecrate implements it fori128andu8with a volatile write and fence), so there is no derive-field gap. TheManuallyDroptest is a real in-place check. - Codegen and Go.
ENCRYPTION_DOMAINS,plaintext_ofandencryption_gapagree withTARGETS,eql_gen.goand the Goeql_test.go/query_test.golists; reason strings are identical across the three.gofmtandgo vetare clean on the touched Go files. The ledger fixtures are wired into tests that fail on drift in both directions (Go compares everything butcand must open the committedc; Rust opens every row and asserts the query file byte-for-byte). - Feature hygiene.
v4is gated atlib.rs, so the ungatedpub mod plaintextis fine. All threeCargo.lockfiles that recordeql-bindingsby path (packages/eql,languages/golang/encrypt/guest,languages/typescript/packages/protect-ffi) passcargo metadata --locked; protect-ffi uses the crate withoutstack-encrypt, so it needs no new entries. chrono 0.4.44 and rust_decimal 1.x are on crates.io, and vitaminc-aead 0.6.0 has thechronoandrust_decimalfeatures the manifest enables. Changeset (@cipherstash/eqlminor), eql-bindings CHANGELOG and Go CHANGELOG are present and accurate; noskills/change is needed (they cover the TypeScript packages, and the SQL domain surface is unchanged).

Re-review of the update to ad62f57.
The range-diff against 2443429 changes only the first commit, and it addresses the earlier review:
- Wiping scope (
plaintext.rs): fixed. The doc now says owned copies, and names theCopystack temporary handed to vitaminc's sink as not wiped, the same as the engine's primitive, chrono and rust_decimal sources. - vitaminc-aead's own
Timestamp: fixed. The module doc says why it isn't reused: the term targets need aCloneplaintext, and it would make chrono a dependency of every build. - docs.rs features: fixed.
features = ["targets", "chrono", "rust_decimal"]. RangeError::LeapSecondwording: fixed. The message now says nanoseconds must be below one second first, with the leap-second case as the explanation.- No frozen row fixture for the six new types: unchanged. This was informational only.
One nit: plaintext.rs lines 19–20 are two consecutive empty //! lines before the table. It renders fine, so drop one only if you're touching the file anyway.
CI is green at this head.

Review attestation — automated /code-review medium + /cross-check-review-findings on head ad62f57.
Critical / blocking: none.
Reviewed: v4/plaintext.rs (range checks, zeroize/Drop, redacted Debug, Encrypt/FromScalar impls, chrono and rust_decimal conversions) and the eql-codegen changes (ENCRYPTION_DOMAINS, plaintext_of, ORDER_PENDING_FAMILIES, encryption_gap ordering, updated tests).
- Ordered date/timestamp/numeric domains stay refused, and the new reason is checked before the block-ORE one.
- The earlier review threads (wipe-scope docs, vitaminc
Timestamprationale, docs.rs features, leap-second message) are fixed in the current code.
Not reviewed in depth: the Go test model and the generated files (eql_gen.go, v4/*.rs), which rely on the regeneration drift checks. I did not run the test suites.
Findings: one non-blocking nit, inline: the unreachable unwrap_or_default() fallbacks would return a wrong value rather than fail if the ranges drifted.
Notes for the author (already in the PR description):
- The frozen
stored_rows_v1.jsonnextest failure also occurs on the base branch. Please make sure it is tracked before the stack merges. - The open ADR-0002 questions (date epoch,
time.Timefor date, decimal type, microsecond truncation vs round-half-even) need a maintainer decision.

Re-review at 5f78cf2e, against the rewritten feat/eql-v4-ordered-ope-types (f3ddc0fe).
The range-diff from ad62f57 is a rebase plus two real changes. The rebase: #1266's two commits (d6c71483e, 31563a5d5) left the PR because they are now in the base, and the two PR commits re-applied over it with no conflict-shaped edits. The author's changes, both in response to the reviews at ad62f57:
- Timestamp equality truncates, and ADR-0002 now says so. The amendment (dated 2026-10-19) strikes the round-half-to-even bullet and replaces it with floor on the signed count since the epoch, giving the reason (one rule for
=and the order term, and no dependence on any one store's parsing). The eql-bindings module doc, README, CHANGELOG, changeset, Go README,doc.goand Go CHANGELOG all say "truncated, never rounded". I checked the claim against vitaminc 0.6.0 rather than the prose:vitaminc_normalize::timestamp(scalar.rs:192) doesdiv_euclid/rem_euclidon the nanosecond count and thensub / 1_000 * 1_000, which is floor on the signed count; the equality path reaches it throughnormalize(scalar.rs:142) and vitaminc-ore's order path throughorder.rs:250, and the ORE domain isvitaminc/ore/value/timestamp-micros/v1(order.rs:54). So the ADR's "both terms normalise through the same function" is literally true. The two new assertions inequality_terms_follow_the_baselinepin it (.1234567to.123456, and-500 nsto23:59:59.999999, which is the floor case), and they pass locally. This closes Codex's P1: it was a design question, the maintainer decided, and the decision is recorded where the next reader will look. - The three
From<&T>conversionsexpectinstead ofunwrap_or_default. Each message names the range and no value. New tests drive the conversion at both ends of each range (MIN_DATE_DAYS/MAX_DATE_DAYSagainstNaiveDate::MIN/MAX,MIN_TIMESTAMP_NANOS/MAX_TIMESTAMP_NANOSagainstNaiveDateTime::MIN/MAX, rust_decimalMIN/MAXand±(2^96-1)at scale 28), so if vitaminc's and chrono's or rust_decimal's ranges ever drift apart, theexpectfires in the unit test rather than in a caller. This closes the automated review's nit.

Re-review of the update to 902bfd3.
Against 07b8b8e, the only change is removing the doubled empty //! line in plaintext.rs. That closes the last nit from review 5566356617. The second commit is unchanged apart from the rebase. No new findings.
The informational item still stands: the six new types have no frozen row fixture yet. CI was still running at the time of this note.

Incremental re-review of the restack to 8d7ee1d (onto #1266's 548c546). Range-diff against 902bfd3: both commits were rewritten, and every changed line is a rebase adaptation to the smallint work now on next (#1267) and in #1266. No substantive edit.
What the rebase changed. This PR no longer touches the smallint rows of eql_gen.go or v4/targets.rs, nor the "no Rust plaintext type" rewording, since next carries those now; the diff is down to the date, timestamp and numeric rows. The codegen targets.rs test loops over ["date", "timestamp", "numeric"] with "", eq producible and ord/ord_ope/ord_ore refused with the order-term reason, and its smallint assertions are gone from this PR. tests/targets.rs no longer expects a smallint reason; v4_types.rs imports smallint beside plaintext; eql_test.go, query_test.go and native_ops.rs keep the base's smallint entries and add the three Eq types; doc.go, both READMEs and the fixtures README merge the two lists. The fixtures README paragraph now reads "Types made producible since are sealed into their own regenerable row fixtures (see the table above), the date, timestamp and numeric types by their own Go model (Ledger)…", which is right with v4_smallint_rows.json in the table. ORDER_PENDING_FAMILIES is still date/timestamp/numeric, so smallint's ordered domains are untouched by this PR's reason ordering. plaintext.rs is identical to 902bfd3, and no fixture changed (v4_ledger_queries.json, v4_ledger_rows.json and the frozen files are byte-identical).
Earlier findings. Everything from reviews 5565822644, 5566356617 and 5566619337 remains fixed. The one informational item, that the six new types have no frozen row fixture yet (v4_ledger_rows.json is regenerable), is unchanged and still informational; the author's reply (thread) left the cut to the maintainer.
Nit: the PR body's "Expected rebase with #1267" paragraph is now done and can go.
Checks (no credentials, at this head, since this branch is not inside #1280's stack): mise run types:check no drift; cargo test --locked -p eql-codegen -p eql-bindings --all-features (eql-codegen 154 unit, eql-bindings 124 unit, every integration suite and the doctests pass); cargo test --locked -p eql-encryption-tests (v4_date_time_numeric 8 passed, 2 ignored without a database; v4_order 12 passed, 2 ignored; v4_types 14 passed, 5 ignored; targets 16, heap_hygiene 2, text_eq 8 passed). CI green at this head.

Remove the stale date/timestamp/numeric sentence from the Smallint entry.
Lines 30-32 say these families are still unproducible because "their Rust plaintext types are not chosen yet". The new entry at lines 33-48 says the base and Eq types are now producible from v4::plaintext. The new entry also says the ordered types are refused only because no order term exists (#1236). The two entries in the same [Unreleased] section now contradict each other. Delete the old sentence or reword it.

I think this is still referring to the now removed wipe method. Probably needs to be rewritten.
Date, DateEq, Timestamp, TimestampEq, Numeric and NumericEq become producible. The engine and the Go SDK already carried the three kinds; what was missing was a Rust plaintext type the by-name dispatch can hold. That dispatch copies the plaintext out of the frame's Protected buffer and needs the copy to be wiped, and chrono's NaiveDate and DateTime<Utc> and rust_decimal's Decimal keep their fields private, so they cannot be. So eql-bindings gets its own plaintexts in v4::plaintext: - Date: an i32 of days since 1970-01-01, the count vitaminc's value model stores a date as; - Timestamp: i64 Unix seconds and u32 nanoseconds, UTC, no leap seconds; - Decimal: an i128 mantissa and a u8 scale. Each is built range checked through vitaminc's own rules (Logical::admits, timestamp_nanos), so a value of one always encrypts, and a refusal is a RangeError that names the range, never the value. Each implements Zeroize and ZeroizeOnDrop, has a redacted Debug and no PartialEq, and is Clone but not Copy: Stack Encrypt hands each term its own copy, and a clone is wiped too. Each describes itself to vitaminc as the same scalar chrono's or rust_decimal's type does, so the leaf is the one any other producer seals. The new chrono and rust_decimal features convert to and from those types; only a leap second is refused, because the ranges are the same. The ordered domains of these families (Ord, OrdOpe, OrdOre) stay refused, with one reason placed before the block ORE one: the engine derives no order term for a date, timestamp or decimal yet. Those domains answer = on the order term and carry no hm, and that is unchanged. The Go SDK's encrypt/eql table, regenerated, marks the six producible, from encrypt.Date, time.Time and encrypt.Decimal, which stashgen already maps to these kinds. The Rust tests cover both entry points, the leaf against chrono's and rust_decimal's, the equality baseline (1.5 = 1.50, one term per microsecond), refusals, and PostgreSQL.
…rom Go, and store Go's rows in PostgreSQL The Go side of the previous commit: an encrypt.Date, a time.Time and an encrypt.Decimal field reach Date/DateEq, Timestamp/TimestampEq and Numeric/NumericEq through encrypt_into, as ADR-0002's host-language rules map them. Nothing in the SDK changed for it; this proves it end to end. A Ledger test model holds one field of each type. It is a model of its own, under Profile's table with columns of its own, because Profile's rows are frozen in stored_v4_rows_v1.json. The Go test checks that every field seals with the right keys and opens back (a decimal with its scale, an instant in UTC with its nanoseconds), that Eq normalises a decimal's scale and compares an instant to the microsecond and by instant rather than wall clock, that out-of-range values are refused with ErrEncoding, and that its Eq queries match the Rust fixture byte for byte. TestV4LedgerRowsMatchTheCommittedFixture writes v4_ledger_rows.json. Rust opens those Go-sealed rows into eql-bindings' plaintexts, and a PostgreSQL test stores them in eql_v4_* columns and runs = with the fixture's queries. The Go README, doc.go, the stashgen README and the CHANGELOG list the six types and the Go type each takes.

Summary
Go and Rust developers can now store dates, timestamps and decimal numbers in EQL columns, and search them by equality. The new producible types are
Date,TimestampandNumeric(stored and read only) andDateEq,TimestampEqandNumericEq(=).Some background for readers new to this:
eql-bindingsis the Rust crate that defines each EQL type and connects it to the engine.The engine and the Go SDK already had these three kinds of value. What was missing was a Rust type to hold the plaintext. The by-name path a Go program goes through copies the plaintext out of the engine's protected buffer, and that copy must be wiped from memory when it's dropped. chrono's
NaiveDateandDateTime<Utc>and rust_decimal'sDecimalkeep their fields private, so they can't be wiped. This PR adds three small types of our own that can.Stacked on #1266.

Review notes
packages/eql/crates/eql-bindings/src/v4/plaintext.rs, then the reason ordering ineql-codegen/src/bindings.rs(encryption_gap). Most of the rest is generated code or tests.Datepayload counts days with 0001-01-01 as day 1. vitaminc 0.6's value model (Logical::Date, which the frame and every producer use) counts days since 1970-01-01.Datefollows vitaminc 0.6, and its constructor is namedfrom_days_since_epochto make that explicit. Should the ADR's table be amended?time.Timefor a date column. ADR-0002 says a Go field whose target is a date family also accepts atime.Time, taking its calendar day in its own location. This PR maps onlyencrypt.DatetoDate/DateEq. Atime.Timefield there is refused as the wrong kind. Adding it needs a write conversion and a decision on what it opens back as (midnight in which zone?). I left it out rather than guess. Do you want it as a follow-up?encrypt.Decimal(vitaminc'svcvalue.Decimal, withParseDecimal), and I used that, which adds no dependency. OK to keep, or should stashgen also acceptshopspring/decimal.Decimal?TimestampEqtruncates an instant to the microsecond (the nanoseconds below it are dropped, never rounded) for both the equality term and the order term, as vitaminc does. It doesn't round half to even the way PostgreSQL does when it parses input. Matching PostgreSQL isn't a goal: timestamps are stored in many places besides PostgreSQL, and a term should mean the same thing in every store and agree with the order term. ADR-0002 is amended (2026-10-19) to say so, and the eql-bindings and Go docs say "truncated" plainly. Unit tests now pin it, including floor behaviour before 1970.stack-encryptstored_rowstest fails locally on the base branch too, and it's outside this diff. It looks like the order-term change in feat(stack-encrypt)!: derive every order term over its ADR-0002 order key, and order floats #1242 / feat(eql-bindings): produce the OPE-ordered EQL v4 types #1266 against the frozen fixture. Flagging it rather than touching a frozen file.(#1236)like the existing reasons (#1132,#1131). They also appear in the generated Go doc comments, as the others already do. The hand-written code comments have no issue numbers.smallint): both add rows toENCRYPTION_DOMAINS, the generated tables and the same catalog test lists, and both reword the "no Rust plaintext type" reason the same way. Whichever lands second regenerates and merges those lists.Summary by CodeRabbit
