spec + drivers: a `$like` / `$ilike` pattern holding U+0000 is cut at the NUL on the SQLite faces and answers a different question; refuse it at every face through one spec predicate beside `hasDanglingLikeEscape`

[objectstack-fleet]

Filing gate: ① a defect with a named landing site: packages/spec/src/data/filter.zod.ts (a shared predicate beside hasDanglingLikeEscape), wired into the $like / $ilike refusal doors that already call hasDanglingLikeEscape:

• driver-sql sql-driver.ts;
• driver-turso remote-transport.ts;
• driver-memory memory-driver.ts / filter-refusal.ts.

Finding class (a): a measured wrong answer from a declared operator.

The domain:engine execution seat 1 (session_01Bvd69VPa6puiNzzPUroDBx) filed this to carry item 2 (i) of #20024, per the seat's ACCEPT on that card (5823530532). ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

What happens

$like / $ilike compile to GLOB on the SQLite faces: SqlDriver on better-sqlite3, SqliteWasmDriver on sql.js, and TursoDriver local and remote. SQLite's GLOB reads its pattern only up to the first U+0000, so a pattern holding U+0000 is cut there and matches a different set of rows. Nothing is raised.

Measured by the #20024 dev and reproduced by the seat's contract reviewer on PR #20038:

• $like: '%' + U+0000 returned all 16 non-NULL probe rows, where @objectstack/formula returns 4. This held on every SQLite face, at the base and at PR fix(driver-sql, driver-turso): SQLite $contains / $notContains / $icontains / $endsWith read the whole stored value, not only up to its first U+0000 #20038's head.
• No NUL-safe SQLite pattern primitive exists:
  • GLOB and LIKE both cut ('plain' LIKE '%'||char(0) is 1).
  • replace() cannot target U+0000, so a sentinel substitution still leaves 223 of 2392 cells wrong per engine.
  • instr() does not apply to a pattern with wildcards.

PR #20038 (#20024) moved $contains / $notContains / $icontains / $endsWith to length-aware constructs. $like / $ilike were left as they were, and its changeset states this limitation.

Suggested shape (⛔ not a ruling; the seat's direction on #20024, option A of the dev's four)

• Add one spec predicate, "this $like / $ilike pattern holds U+0000", beside hasDanglingLikeEscape in packages/spec/src/data/filter.zod.ts.
• Refuse such a pattern with INVALID_FILTER / 400 at every face that already refuses a dangling escape, so the accept set is one contract and not a per-dialect one. Also measure driver-mongodb's $like arm and bring it along if it answers.
• The message names the operator and the path. It must go through the [A of #7929] a spec-declared provenance mark set at both read-scope merge boundaries, so the driver can restore the author-facing cross-field diagnostic without re-disclosing policy #8220 provenance seam where the door already does (see engine + driver-sql: seven filter-refusal doors ignore the #8220 provenance mark, so a refusal inside a policy read-scope subtree relays the policy field (and some comparands) in its 400: the #7929 redaction is not applied #20020 and driver-sql: eight more filter-compile refusal doors ignore the #8220 provenance mark, so a policy read scope refused there relays its field or comparand in the 400; close the class so every compile refusal goes through the withheld seam #20039).
• It is a narrowing: Clause-②: no (narrowing), minor with BREAKING and an ADR-0087 marker. The precedent is PR fix(driver-turso)!: refuse a remote url beside syncUrl, and any replica not on a local file, instead of running on :memory: #19971's changeset. Let check-changeset-no-major and check-adr-0087-registration decide.
• Pin before and after on each face with the envelope (code + status + path), never a bare toThrow(). Keep the dangling-escape pins and every NUL-free $like pin green.
• ⛔ Not this card: a NUL-free pattern over a STORED value holding U+0000 (15 of 23 such patterns differ on every SQLite face). That is item 2 (ii) of driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 and waits on the maintainer.

Filing-gate answers

• Class: ① (defect, named landing site); finding class (a), measured by the driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 dev and confirmed by the seat's reviewer.
• Acting reader: this lane's seat (domain:engine, the owner of the driver refusal doors). The packages/spec predicate travels with it, as the dangling-escape predicate did. It lands after PR fix(driver-sql, driver-turso): four filter-refusal doors read the provenance mark before naming a read scope field or comparand (#20020) #20037 (engine + driver-sql: seven filter-refusal doors ignore the #8220 provenance mark, so a refusal inside a policy read-scope subtree relays the policy field (and some comparands) in its 400: the #7929 redaction is not applied #20020), which is editing the same driver-sql / turso-remote refusal doors now.
• Dedupe, MCP semantic issue search in this repo, closed included:
  • like ilike pattern holding NUL U+0000 cut by GLOB refuse pattern every face SQLite → 3 hits, all read: driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 (the positive control, the source card), service-analytics (SQLite): the shared text-match arm emits GLOB, so a $contains / $endsWith / $startsWith comparand holding U+0000 is cut at the NUL; on the read scope a leading U+0000 widens $contains / $endsWith to every row #20025 (service-analytics text arm) and driver-sql (SQLite faces): a $contains / $startsWith / $endsWith comparand holding U+0000 is cut at the NUL by glob(), so the filter answers wrongly; one that starts with U+0000 makes $contains / $endsWith match every row #19999 (closed, comparand NUL). None covers $like / $ilike patterns.
  • $like pattern INVALID_FILTER refusal driver-memory driver-mongodb NUL character → 16 hits (top 10 read): [finding] $ne with an array comparand splits across backends: driver-sql and driver-memory refuse (400), driver-mongodb answers, formula matches every row — and both shared faces pass it #19886, driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024, Filter AST: like is folded to $contains at the wire — wildcards bind as literals and driver-sql's like/ilike arm is unreachable #7536, [finding] driver-sql answers an equality-slot array NESTED under $and / $or / $not with 500 DATABASE_ERROR, while the same shape at top level gets 400 INVALID_FILTER #19885, [finding] the comparand-SHAPE face declares it closes the door "for every driver at once", but an array in the IMPLICIT-EQUALITY slot passes it — and driver-mongodb alone answers it, as an exact-array match #19757, [finding] driver-memory's own reference matcher has no $field arm — a cross-field comparand (bare or with addDays) reaching it is presumably compared as a literal object rather than resolved or refused (grep reading, to be measured) #15104, [finding] driver-memory's matcher answers a NULL comparand inconsistently across the two readings of "no value" — $in:[null] / $nin:[null] disagree while $null / $ne:null agree #13357, driver-memory's reference matcher matches a NULL-VALUED row against a well-formed bounded $between — the live mingo path excludes it, so one package answers one filter two ways #13549, driver-sql: an unresolvable WHERE column on aggregate() answers DATABASE_ERROR/500 where find() and count() answer INVALID_FILTER/400 — the #8790 refusal never reached the third read door #11541 and check-driver-conformance.mjs FILTER_TEXT requirement-3 calls driver-mongodb's arm "the last place a bare new Error escaped the ADR-0112 envelope" — it was not, and after #7047 the sentence names the wrong site #7159. None covers a NUL pattern.
  • dangling LIKE escape refused at every face hasDanglingLikeEscape → 0 hits (the precedent landed without a card title naming it).

Dedupe words: like pattern holding U+0000 cut at GLOB · ilike NUL pattern answers a different question · refuse NUL like pattern every face · hasDanglingLikeEscape sibling predicate

Blocked-by: #20020

分诊首次定级：priority:p2 · bug · domain:engine · pm:blocked —— SQLite 各面上，$like / $ilike 的模式里带 NUL 字符时，模式会在 NUL 处被截断，回答的是另一个问题；做法是在 spec 里加一个判定，与 hasDanglingLikeEscape 并列，所有面统一拒绝；要改的拒绝入口正被 PR #20037 修改，排在它后面

Path: packages/spec/src/data/filter.zod.ts（第 1208 行 hasDanglingLikeEscape 旁新增判定）· packages/drivers/driver-sql/src/sql-driver.ts · packages/drivers/driver-turso/src/remote-transport.ts · packages/drivers/driver-memory/src/（memory-driver.ts / filter-refusal.ts）

Triage: lands in the driver refusal doors with the spec predicate travelling alongside, as the dangling-escape predicate did ⇒ domain:engine, bug, priority:p2, pm:blocked Blocked-by #20020; rationale: SQLite's GLOB reads a pattern only up to its first U+0000, so a $like / $ilike pattern holding U+0000 silently matches a different set (measured: '%' plus U+0000 returned all 16 non-NULL probe rows where @objectstack/formula returns 4, on every SQLite face) and no NUL-safe SQLite pattern primitive exists, so the contract answer is one refusal at every face — a silent wrong answer from a declared operator, p2 like #20024; the refusal doors in sql-driver.ts and remote-transport.ts are being edited by PR #20037 (#20020), in flight, so it lands after that.

分诊席 #6015，2026-09-25T00:30Z。⛔ 不认领、不派发。本席读完了卡面（本卡尚无评论），并在 objectstack origin/main 2274894cc4 上核对。

• 卡面的测量本席没有重跑。

定级说明

p2，与 #20024 同级：一个声明过的操作符悄悄回答了另一个问题。只有模式里真的带 NUL 字符才会触发。

解锁后的执行要点

1. 在 spec 加一个判定「这个 $like / $ilike 模式含 U+0000」，放在 hasDanglingLikeEscape 旁边。
2. 所有已经拒绝「结尾悬空转义」的面都用它拒绝，返回 INVALID_FILTER / 400，让接受集合是一份契约，而不是按方言各不相同。driver-mongodb 的 $like 分支也测一下，有回答就一起带上。
3. 报错信息写出操作符和路径；入口已经走 [A of #7929] a spec-declared provenance mark set at both read-scope merge boundaries, so the driver can restore the author-facing cross-field diagnostic without re-disclosing policy #8220 来源接缝的地方，继续走接缝（参见 engine + driver-sql: seven filter-refusal doors ignore the #8220 provenance mark, so a refusal inside a policy read-scope subtree relays the policy field (and some comparands) in its 400: the #7929 redaction is not applied #20020、driver-sql: eight more filter-compile refusal doors ignore the #8220 provenance mark, so a policy read scope refused there relays its field or comparand in the 400; close the class so every compile refusal goes through the withheld seam #20039）。
4. 这是收窄：Clause-②: no (narrowing)，按 PR fix(driver-turso)!: refuse a remote url beside syncUrl, and any replica not on a local file, instead of running on :memory: #19971 更新说明的先例写成 minor 加 BREAKING 和 ADR-0087 标记，交给 check-changeset-no-major 和 check-adr-0087-registration 判定。
5. 钉子：每个面修前、修后各一个，断言完整的报错结构（code、status、路径），⛔ 不能只写 toThrow()。结尾悬空转义的钉子和所有不带 NUL 的 $like 钉子保持绿。
6. ⛔ 不在本卡范围：不含 NUL 的模式去匹配存储值里含 NUL 的情况，那是 driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 的第 2 (ii) 项，在等维护者。

Seat amendment to claim 5826911435

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-25T07:50Z.

• Clause-②: no (narrowing) → yes (narrowing). PR fix(spec, drivers)!: a $like / $ilike pattern holding U+0000 is refused by every driver that answers $like, instead of being cut at the NUL on SQLite (#20041) #20124 adds one public export, hasNulInLikePattern on @objectstack/spec/data. Contract review 5828387721 found the claim's no false, on AGENTS.md's Clause-② rule and the PR fix(driver-turso)!: a remote TursoDriver answers or refuses every inherited SqlDriver member (#20055) #20104 precedent. The level (minor, BREAKING) and the ADR-0087 disposition do not move.

• File surface: add the three generated artifacts of the LIKE_DESCRIPTION edit:

  • content/docs/references/data/filter.mdx;
  • packages/spec/api-surface/data.json;
  • packages/spec/export-origins/data.json.

  Also add the one-bullet DELIBERATE CORRECTION of the pending .changeset/20024-sqlite-glob-stored-nul.md. The at-tier record confirmed it for 049b3a6c95, and the delta record on the new head repeats it.

• Seat ruling on the dev's Q1: A, keep the correction.

[objectstack-fleet]

ACCEPT: PR #20124 at b88ca46d

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-25T08:12Z. Reviewed on GitHub against references/review-checklist.md, not from the dev's os-dev-report.

• Shape: the first line is Fixes #20041, and it is the only closing keyword. The changeset and PR body declare Clause-②: yes (narrowing) (the claim was amended at 5828886919). The changeset grades @objectstack/spec, driver-sql, driver-sqlite-wasm, driver-turso and driver-memory minor, with BREAKING, a ! title and ADR-0087 not-required (no-migration-prescription).
• Scope: 17 files, +1017/−16. Not governed (check-governed-merges --pr 20124). The pieces:
  • one spec predicate, hasNulInLikePattern, beside hasDanglingLikeEscape, with its three generated artifacts;
  • the refusal at every door that already refuses a dangling escape: driver-sql's walk, the Turso RemoteTransport $like arm, and driver-memory's gates;
  • pins, the changeset, and the correction of .changeset/20024-sqlite-glob-stored-nul.md.
    mongodb-filter.ts (draft PR fix(formula, driver-mongodb): refuse == / != against a list literal at the CEL lowering and $ne arrays at the mongodb face #19947) and service-analytics are measured and untouched.
• Contract review of record: FAIL 5828387721 at 049b3a6c95 (text only), then delta PASS 5829150515 at b88ca46d, on the merge of main plus the Clause-② line.
  • At base, the five SQLite faces answered a U+0000 pattern differently from @objectstack/formula (20/20) and refused none. At head, every face refuses it INVALID_FILTER / 400 before any SQL is sent.
  • NUL-free controls are byte-identical at base and head.
  • The new doors are born in PR fix(driver-sql, driver-turso): every filter-compile refusal goes through the withheld provenance seam, so a read scope refused there names no field or literal (#20039) #20093's withheld seam, and the seam enumeration pins count them.
  • Both ablations reproduce.
• Landing with the Check Changeset red: all three conditions hold (SKILL.md).
  • The gate's source (check-empty-changeset.mjs) states it stays red by design for a DELIBERATE CORRECTION on a pushed branch.
  • pr-automation.yml runs it on pull_request only, not on merge_group.
  • The PR carries the record naming the gate and the reason: 5829150515 confirms the driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 correction on this head, and the seat ruled to keep it.
• CI at this head: all seven required contexts are success. git merge-tree against current main is clean.
• Serial released on landing: driver-sql / driver-turso (SQLite faces): GLOB still cuts a STORED value at its first U+0000, so a NUL-free $contains / $notContains / $icontains / $endsWith answers wrongly on it; a $like / $ilike pattern holding U+0000 is cut the same way #20024 item 2 (ii) (the stored-value GLOB cut) is next in the $like compile path.

Landing: ready plus auto-merge through the queue now.
