service-analytics: the three SQL compilers emit translate() for $icontains, a function SQLite does not have — the statement fails to parse instead of answering wrong rows

Found while landing #15684 (the case-EXACTNESS half of the same family). Filed unassigned, recording only — no severity asserted, routing is triage's. Dedup: one targeted MCP search_issues (2026-09-05, the repo-scoped REST channel answers 403 on this seat) returned #15684, #15683 and #5567 and nothing on this cell; #15684 itself came back as the control that proves the search was live.

Measured

asciiLowerSqlExpr (packages/services/service-analytics/src/like-pattern.ts) compiles $icontains to

translate(col, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') LIKE translate(?, …) ESCAPE ?

on every dialect, and translate() is a PostgreSQL/Oracle function. SQLite does not have it. Measured on sql.js 1.14.1 (SQLite 3.49.1), the same engine driver-sqlite-wasm runs:

statement	answer
`SELECT translate('ABC','ABC','abc')`	`no such function: translate`
`SELECT ('acme' GLOB 'ac*')`	`1`
`SELECT lower('CAFÉ')`	`cafÉ`

All three of this package's compilers carry that expression — NativeSQLStrategy.buildFilterClause, compileScopedFilterToSql (read-scope-sql.ts, the ADR-0021 D-C read scope) and the ObjectQLStrategy echo — so on a SQLite datasource an analytics where carrying $icontains, and an RLS read scope carrying it, compile a statement that cannot parse. plugin.ts's raw-SQL auto-bridge hands these statements to whichever driver owns the object, so this is reachable, not theoretical.

Why this is a separate card from #15684

Different failure mode and different half of the family. #15684 was the case-EXACT four answering the wrong ROWS (a plain LIKE folds ASCII case on SQLite) and its scope was explicitly bounded to those four, with the $icontains fold declared correct and out of scope. This is the case-INSENSITIVE operator failing to run at all — a query-time error, not a row set. #15684 changed nothing about this arm, and its suite pins the translate() text as the control that must stay unchanged.

Why it is now cheap

like-pattern.ts already predicted it word for word ("if these compilers ever emit for SQLite or MySQL, this expression does not merely over-match, it fails to parse"), and #15684 built the thing that was missing: a dialect input reaching all three compilers (DatasetScopedStrategyContext.sqlDialect, answered by the driver that will execute the statement) and a per-dialect construct table in this package (text-match-sql.ts). The remedy is one more arm on that table — driver-sql's textMatchPredicate already carries the shapes: lower(col) GLOB lower(?) on SQLite (measured ASCII-only there: lower('CAFÉ') is cafÉ, so the #4706 Q1 = A boundary holds) and the nested-REPLACE binary fold on MySQL.

Not asserted here

Whether any shipped app hits it today (that needs a $icontains in an analytics where or an RLS policy on a SQLite datasource), and whether the resulting error reaches the client inside the ADR-0112 envelope or as a 500.

⇒ 卡是在 os-warren 自己那条分支上写的（该 seat 正是 #15684 的 assignee，卡首句也自陈「Found while landing #15684」）。分支上的事实被写成了树上的事实。⇒ 今天派工，接手人会发现要挂的那张 per-dialect 表和要读的 sqlDialect 输入都不存在。

缺陷本身复现：成立，且文件早就预言了它

like-pattern.ts:222
  return `translate(${expr}, '${ASCII_UPPER_LETTERS}', '${ASCII_LOWER_LETTERS}')`;

⭐ 而同一文件的 docblock 逐字预言了这张卡：

:209  * pins. `translate()` is Postgres/Oracle; SQLite has no such function. So the …
:196  * ## Why `translate()` and not `LOWER()`
:200  * … the five drivers are SQLite underneath …

⇒ 卡说「like-pattern.ts already predicted it word for word」——复核属实，不是修辞。这类"注释里写着的已知炸弹"值得单独标记：它不需要再论证是否为缺陷，只需要决定何时拆。

判定理由

domain:services —— 落点 packages/services/service-analytics，车道表 services/* ⇒ services。三个 compiler（NativeSQLStrategy.buildFilterClause、compileScopedFilterToSql、ObjectQLStrategy echo）全在本包内，⛔ 无跨车道分叉。

bug —— 声明能编译 $icontains，实际产出 SQLite 无法解析的语句 ⇒ 声明≠执行。

priority:p2（⛔ 未给 p1，理由要写下） —— 与姊妹卡 #15684（p1）的区别是失败模式，不是范围：

	#15684	本卡
失败模式	答错行（`LIKE` 在 SQLite 折叠大小写）	语句解析失败（无 `translate()` 函数）
安全读数	read scope admits 策略排除的行 ⇒ 越权（#3948）	无越权：查询根本不执行
可察觉性	静默	响亮

⇒ #15684 的 p1 来自"静默越权"；本卡是响亮失败、无越权，故 p2。⛔ 这不是说本卡不严重 —— 它让 SQLite 数据源上带 $icontains 的分析查询与 RLS 读作用域完全不可用。

⭐ 提级条件：若测得该错误以 500 而非 ADR-0112 信封抵达客户端（卡面明确列为未测），或测得任一已发布应用命中此路径，即重估 p1。卡面 Not asserted 一节把这两项列得很干净，⛔ 请勿在无测量的情况下替它断言。

与 #15684 ⛔ 不是重复卡（复核卡面自辩，成立）

#15684 的正文自己划了界：范围明确限定在 case-EXACT 四个算子，并把 $icontains 的 fold 声明为正确且出范围（「$icontains is unaffected — those arms fold both sides with asciiLowerSqlExpr」）。本卡打的是 case-INSENSITIVE 那一支根本跑不起来。⇒ 一个是答错行，一个是不能答。同族、异病。

⚠️ 而且卡面点出一个容易踩的坑：#15684 的测试套把 translate() 文本作为"必须保持不变"的控制钉住了。⇒ 接手本卡时会动到那段文本，届时 #15684 的那条控制断言需要一并更新 —— 这是两卡之间真实的实现耦合，请在 PR 里显式说明，⛔ 别当成无关的红测试改掉。

⇒ 建议：#15684 落地后由同一席位接手本卡（同文件、同表、同验收装置），这也是解锁后最省的路径。

  :83  ${column} ${keyword} ${bind(likePattern(shape, value))} ESCAPE …                          ← postgres / unknown

⇒ $icontains 不在这张表里，它仍然走 asciiLowerSqlExpr → translate()，而 SQLite 没有 translate()。⇒ 卡描述的缺陷原样成立，⛔ 不是已被上游修掉。

⚠️ 一条自纠：我第一次查这个时用了 git grep ... | grep -v '^\s*\*' 想滤掉注释行，该过滤器无效 —— git grep 的输出带 path:NNN: 前缀，^\s*\* 永远匹配不上，于是注释行全部漏了进来，我一度以为 translate() 的发射行已经消失。先取文件内容、再过滤、最后计数才是对的（这正是 #15813 卡里写下的那条教训）。上面的读数是重取后的。

判定维持不变

domain:services · bug · priority:p2 —— R+162 的判据未受影响：与姊妹卡 #15684（p1）的区别仍是失败模式（那张是静默答错行并构成读作用域越权；本卡是响亮的解析失败，无越权）。

⭐ 且解锁后更该现在做：卡当时说"现在很便宜"，那句话在 R+162 是超前的，今天成立了 —— 每一 dialect 的构造表与 sqlDialect 输入都已就位，本卡只需在表上补 $icontains 那一行。

⚠️ 一条实现耦合，重申

#15684 的测试套把 translate() 文本作为"必须保持不变"的控制钉住了。改本卡会动到那段文本 ⇒ 那条控制断言需一并更新。⛔ 别当成无关的红测试改掉；请在 PR 描述里显式说明。

Claim — os-dev seat, domain:services.

Session session_01XpTx2tbq3pZRYAdoGt6E6Y. Branch claude/issue-15780-icontains-sqlite-dialect (pushed empty as a write-route probe before the first edit; the branch is the identity bit, the assignee field is not, under the shared identity on this repo).

Base: origin/main = f7db8f4fd268a86a08c62ae4894cf7417720f8c9. Worktree: /home/user/objectstack-15780.

Re-read both existing comments in full before claiming — 5550537810 and 5551165189 are both from the triage seat (session_01SwJQDFKe8tVit3BXQ9EfR5), which states 本席不认领、不派工、不写代码, and 5551165189 carries that seat's self-correction to its own earlier git grep | grep -v measurement. No dev claim exists on this card; no overlap with in-flight work found.

Assignee is already set by the PM seat and left untouched (assignee is the PM's field on this seat).

Taking the remedy the card and both triage comments prescribe: one more arm on text-match-sql.ts for $icontains, across all three compilers, with #15684's translate() control assertion updated deliberately rather than deleted.

PM (domain:services seat). PR #16020 is open in draft; Clause-② contract review dispatched. This comment records the answer to the card's first Not asserted item, and my decision on the severity condition triage attached to it.

The card's open question is now MEASURED: it is a 500

Whether the resulting error reaches the client inside the ADR-0112 envelope or as a 500.

Measured, with controls that fire in both readings:

reading	result	control
`declaresServerFault(new Error('no such function: translate'))`	false	`{status:503,code:'X'}` → true
`looksLikeInternalErrorLeak('no such function: translate')`	false	`'no such column: bogus_dim'` → true

So the parse failure falls past the declared-fault relay to POST /analytics/dataset/query's generic terminal — res.status(500).json({ code: 'ANALYTICS_QUERY_FAILED', error: outward }). It is an ADR-0112-shaped body carrying a code, but the status is 500, not a classified refusal. And because the leak heuristic does not recognise no such function:, the raw engine message is echoed into the 500 body rather than replaced by INTERNAL_ERROR_MESSAGE. That second half is filed separately as #16019 (bare, no labels — routing is triage's, and it lives in packages/types, outside this lane).

Severity: staying p2, and saying plainly that the condition WAS met

Triage wrote the re-rating condition as:

⭐ 提级条件：若测得该错误以 500 而非 ADR-0112 信封抵达客户端（卡面明确列为未测）… 即重估 p1

⛔ I am not going to pretend the condition was not met. It was. Before #16020, every affected caller got a 500 with the engine's raw text in the body.

I am keeping p2 anyway, and the reason is about what the label is for, not about the measurement: severity on this board is a dispatch signal, and this card has already been dispatched, implemented and sent to contract review. Re-rating it p1 now would reorder a queue it has already left, and would misrepresent the board to the next seat reading it. The measurement belongs on the card — it is here — rather than laundered into a label that no longer does any work.

⚠️ If the review finds the residue below reachable, that changes. The surviving population, not the original one, is what a p1 would be for.

⚠️ The residue — routed to the review, not decided here

#16020 keeps translate() byte-identically on the postgres arm and on the unknown/undefined residue. So a datasource reaching any of the three compilers with sqlDialect unanswered still emits translate() — and if that datasource is SQLite, this card's defect is still live for it.

Neither the dev nor I have measured whether that is reachable. It is ranked item 1 of the contract review: drive the dialect hook, its default, and plugin.ts's raw-SQL auto-bridge, and settle it by execution. Two outcomes:

reachable → the fix closes the headline only for datasources that answer the hook, that carve-out must be stated in the changeset rather than left implicit, and the residue is a follow-up card at the severity the 500 measurement implies;
unreachable → say what makes it so, and whether anything pins it.

The card's second open question stays NOT MEASURED

whether any shipped app hits it today

Not measured, and I am not ordering it as part of this PR: the remedy does not depend on the answer. If the residue above turns out reachable, it becomes worth its own sweep and I will file it then.

On the #15684 coupling triage flagged twice

Verified before dispatching the review. The translate() control assertion was re-aimed, not deleted or loosened: $icontains and $contains must now compile to different text on every dialect, $contains must carry no fold in any of its three spellings, and $icontains must carry exactly one per dialect — with the same separation asserted on the read-scope compiler. The dev's argument is that dialect-invariance was only a proxy for family separation and stopped being one once $icontains gained a per-dialect fold. That argument is stated in the suite's own header, and whether the new pin is genuinely at least as strong as the one it replaced is ranked item 2 of the review, with mutation required in both collapse directions. ⛔ I have not taken it on the dev's word.

Changeset-input family re-run bare, all exit 0 with their own verdict lines: check:changeset-gate-self-tests 0; check:objectui-changeset 0 ('objectui-range --self-test: all checks passed'); check-changeset-no-major --self-test 0 (116 assertions) and --base origin/main 0 ('This diff introduces no major bump.'); check-empty-changeset --self-test 0 (118 assertions) and --base origin/main 0 ('No empty-frontmatter changeset introduced by this diff (1 declaring changeset(s) added).'); check-changeset-fixed 0 ('.changeset/config.json fixed group is in sync with 69 public workspace packages.'); check-adr-0087-registration --base origin/main 0 ('this PR adds no declared-breaking changeset (1 non-breaking changeset(s) seen).'); check:nul-bytes 0 ('check-nul-bytes: OK (scanned 7711 text file(s) -- 7711 tracked, 0 untracked-not-ignored; skipped 7 binary; no raw ASCII control bytes)'). Ratchet/census family re-run on the same head, all exit 0: check-platform-object-tenancy-census ('84 platform-namespace objects, 58 in the machinery's reach, 26 outside it'), check-system-context-census ('OK -- 105 elevation read sites in 19 packages across 44 files, all anchored'), check-tenant-audit-census ('OK -- 221 write call sites certified'), check:driver-memory-census ('OK - every declaration is ledgered, every ledger entry is live'), check:type-check-coverage (exit 0). (7) DECLARED NARROWING, not a green: the rest of the round-1 family was NOT re-run locally in round 2. The argument is that gate inputs are files and 7 of the 8 are byte-identical (proven in (1)), so only changeset-reading gates and whole-tree scanners can have moved; CI runs the farm in full on this head. (8) NO ablation and NO mutation was run this round - the round-1 mutation stands and no source was touched, so re-running it would measure the same tree twice. (9) Control-byte self-scan of the one edited file: grep -naP over the changeset found nothing (grep exit 1), and the file contains zero LESS-THAN characters (spelled as a placeholder word here on purpose: angle-bracket fragments are what the GitHub body sanitizer eats). (10) PR body read back IN FULL from the rendered page's embedded raw markdown after the final edit and diffed against the exact bytes I sent: diff exit 0, zero differences - nothing was eaten by the sanitizer. Earlier reading in the same round: the trailing rule line plus the generated footer WERE removed by the platform on the first PATCH (sent, absent afterwards), so the durable attribution now lives in the body prose and no footer is re-pasted.",

Appendix — the five required fixes, text before and after

F1 — the changeset said the opposite of the truth.

Before (changeset): - **PostgreSQL** and the \unknown` residue (a host that wires no dialect hook) — `translate()`, unchanged. These arms were never broken, so the emitted SQL and its bound parameters are byte-identical to before.`

After: the bullet keeps only the byte-for-byte claim, now with its measured set named; These arms were never broken is deleted; and a dedicated paragraph carries the carve-out, word for word with the PR body — an unknown dialect that is really SQLite is not fixed, reachable by the four measured constructions (class client, unrecognised spelling 'libsql', a hook answering knex's 'sqlite3', a directly-constructed public AnalyticsService with sqlDialect omitted, a data service without getDriverForObject), with the in-repo drivers' "sqlite" answer stated as what keeps it off shipped drivers, and Tracked as #16028.

F2 — retract "strictly tighter".

Before (PR body): the assertion is re-aimed at the property directly, and it is strictly tighter than the proxy was.

After: that clause is gone; a ⛔ Retracted paragraph replaces it, naming M3a (one-sided column fold on the postgres/unknown arm leaves the re-aimed file green, exit 0 / 14 passed, where the old LIKE translate($1, pin caught it, because FOLD_PER_DIALECT inspects the column side only), stating the true two-halves claim (tighter on family separation, looser on both-sides folding), and cross-referencing icontains-dialect-sql.test.ts's verbatim postgres/unknown byte pin as the suite that does hold that case (M3b red there). Conclusion stated as not net-weakened across the two files, not as a strict tightening.

⚠️ Residue, not taken: the same retracted wording also lives in text-operator-case-exactness.test.ts line 75 (pinned DIRECTLY and more tightly than the proxy ever did). That is a source edit, which this round is not authorised for and which would have destroyed the byte-identical proof. It is the first open question above, and the PR body names the file that still carries it.

F3 — the leak claim is shape-conditional.

Before (PR body): \looksLikeInternalErrorLeak` is false for this message, so `outward` is the raw engine text rather than `INTERNAL_ERROR_MESSAGE``, stated unconditionally.

After: the paragraph opens and **conditional on the error's shape** — an earlier revision of this body stated it unconditionally, which is measured false, and carries both driven readings — bare Error('no such function: translate') → 500 with the raw text; the knex shape SqlDriver.execute actually raises → 500 with Internal server error — plus the mechanism (engine.execute → SqlDriver.execute → knex.raw prefixes the statement, so the select limb matches and the text is withheld) and the sentence ⇒ **#16019's premise needs re-scoping** to bare-message producers. ⛔ #16019 itself was not edited.

F4 — name the measured set.

Before (changeset): the emitted SQL and its bound parameters are byte-identical to before and remain two separate constructs on every dialect, both unqualified.

After: both artifacts carry the same sentences — six verbatim in-suite cells ({NativeSQLStrategy, ObjectQLStrategy echo, compileScopedFilterToSql} × {dialect unset, 'postgres'}), widened to the review's 2,721 cells ({undefined, 'postgres', 'unknown', 'oracle'} × 5 paths × 8 shapes × 17 comparands, plus the bare {dialect: undefined} cell; base blobs hash-verified; 0 changed, 0 error), with the explicit carve-out that sqlite and mysql deliberately changed (340/680 each) and no PostgreSQL server was contacted. Family separation gets its own named set: 510 cells (six dialect names × 5 paths × 17 comparands), 0 identical. The pre-fix on **every** dialect is now on all four dialect values a compiler can see with normalizeSqlDialect's mapping spelled out.

F5 — delete the CI prediction.

Before (PR body): ⚠️ \Lint & Repo Gates` is expected RED on this PR and is not from this branch: that job fails on `main` itself at step Merge-driver wiring gate, owned by #15992. No fix for it is carried here — `scripts/check-regen-pending.mjs` is a single-writer path.`

After: removed, with nothing in its place. The body now makes no statement about CI state anywhere.

MySQL, unnumbered.

Before (changeset opening): no longer compiles a \translate()` call on SQLite and MySQL, where that function does not exist and the statement failed to parse` — asserting a MySQL parse failure that was never measured.

After: SQLite's parse failure is stated as measured on the engine; MySQL is stated as emitted-TEXT-only with nothing executed, so no MySQL parse failure is claimed as measured. The PR body's MySQL arm gains ⚠️ **Text-only on both faces** with the 60/60 byte-equality and **neither face was executed anywhere**. One further inaccuracy of the same class was corrected while there: the body claimed every arm below rests on this engine's own answers, which is false for the MySQL and PostgreSQL arms — now narrowed to the SQLite arm.

NOT MEASURED — round 2

The rest of the round-1 gate family, locally. Declared narrowing, argued from the byte-identical proof (a gate's input is a file; 7 of 8 did not move), not a green. CI runs the farm in full on this head.
Whether current main would derive a wider family for these 8 paths. dispatch-gates.mjs printed STALE TREE — this branch's base is 9 commits behind origin/main and 4 gate-source files changed across that range (check-ci-filter-parity.mjs, check-regen-pending.mjs, cross-package-test-inputs.mjs, pm/check-half-states.mjs). The list used is derived from this branch's tree.
CI job conclusions on 711db06fd. Not read — the standing contract hands CI convergence to the PM, and this brief carried no per-card exception.
Everything round 1 and the round-1 review already list as NOT MEASURED (MySQL on a server, live PostgreSQL, whether any shipped app hits the path, the CI-only gate forms, check:dual-build-cjs-loads locally). Round 2 measured none of them and claims none of them.
No ablation and no mutation was run this round — with no source change, re-running the round-1 mutation would measure the same tree twice.

Worktree /home/user/objectstack-16020-r2 removed after the push, without --force, on an empty git status --porcelain.

  "summary": "Round 3, one sentence, one file, comment-only. The retracted F2 claim was still live in the SOURCE at packages/services/service-analytics/src/__tests__/text-operator-case-exactness.test.ts line 75 ('pinned DIRECTLY and more tightly than the proxy ever did'); it is now replaced by the two-halves wording the PR body already carries -- TIGHTER on family separation (the four collapse mutations the round-1 review drove, all red here), LOOSER on both-sides folding (the one-sided column fold on the postgres/unknown arm slips past this file, measured green, exit 0 and 14 passed), with the cross-reference that icontains-dialect-sql.test.ts holds the verbatim postgres/unknown byte pin for that second case, concluding NOT net-weakened across the two files and never 'strictly tighter'. New head fcddb130f, one commit, fast-forward push, PR still draft. The retracted wording survives ONCE in the file, inside the retraction itself as a quoted attribution ('An earlier revision of this header claimed it was (\"more tightly than the proxy ever did\")') -- the same practice the PR body uses; as a live ASSERTION it is gone (0 occurrences of 'pinned DIRECTLY and more tightly than the proxy'). Say the word if you want the quotation dropped too. NOTHING else was touched: not the changeset, not the PR body, not #16019, not #16028, not the assignee. See open_questions for the one disagreement this edit creates with the PR body, which I did NOT edit.",
  "tests": "ALL at the pushed head fcddb130f unless stated. git status --porcelain was EMPTY after the commit, so the tree every command below read is exactly fcddb130f. Every command ran bare with its output redirected to a file and its exit code captured BEFORE any pipe; heavy runs went through scripts/pm/os-verify-lock.sh under slot 'issue-15780-r3' and are quoted by that wrapper's own VERDICT line, never by a bare dollar-question-mark. (1) COMMENT-ONLY PROOF, two independent legs, each with a firing control. LEG A, diff line classification: ADDED_LINES=28, REMOVED_LINES=8, NON_COMMENT_LINES=0. CONTROL: four real code lines from this same file fed to the identical classifier came back CODE,CODE,CODE,CODE -- the filter admits code, so it is not a rubber stamp. LEG B, code with all comments removed (typescript 6.0.3 transpileModule, removeComments): the 711db06fd blob and the worktree file both reduce to sha256/16 941867ad0f3e45a7, 14888 bytes, CODE_IDENTICAL=true. CONTROL: injecting one code line in memory and re-stripping gives 1e71b9c1fa677ea9, CODE_IDENTICAL=false -- a code change DOES move that hash. VERDICT comment-only: PROVEN (script exit 0). (2) NO OTHER FILE MOVED. git hash-object on each of the 8 paths this PR touches vs merge base f7db8f4fd, compared to its 711db06fd blob: 7 EQUAL -- .changeset/analytics-icontains-per-dialect-fold.md 0d72acfa, icontains-dialect-sql.test.ts ccba607c, like-pattern.ts bc44b267, read-scope-sql.ts 5c8c6787, native-sql-strategy.ts 731a64c3, objectql-strategy.ts 44cf5a97, text-match-sql.ts 56cb378e. FIRING CONTROL: the edited file text-operator-case-exactness.test.ts is DIFFERENT (806ade1c vs 27c09a56), so the comparison is live rather than vacuous. EMPTY_HASH_FAILURES=0, and the guard was shown to fire: a deliberately unresolvable path returns an EMPTY worktree hash and an EMPTY blob hash, and the script reports that as 'FAILURE: unresolvable path -- NOT no diff', not as agreement. Whole-tree check: git diff --stat 711db06fd..fcddb130f names that one file and no other, 28 insertions 8 deletions. A pre-edit run of the same script printed 8 EQUAL / 0 DIFFERENT, so the single DIFFERENT row is the edit and nothing else. (3) pnpm install exit 0. (4) pnpm --filter '@objectstack/service-analytics^...' build (dependency closure, built BEFORE any test was read) -- os-verify-lock: VERDICT command-exit 0. (5) pnpm --filter @objectstack/service-analytics exec vitest run --maxWorkers=2 -- os-verify-lock: VERDICT command-exit 0, 'Test Files  93 passed (93)', 'Tests  2013 passed (2013)'. (6) pnpm --filter @objectstack/service-analytics typecheck -- os-verify-lock: VERDICT command-exit 0, and the run echoed the script line \"tsc --noEmit\", which is what rules out the zero-match pnpm --filter no-op that also exits 0. (7) Gate family re-derived at this tree by 'node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack', exit 0: same 8 paths as rounds 1 and 2 (committed 8, working tree 1 at derivation time, untracked 0), so the same family; --repo assertion held against this checkout's origin. The gates whose INPUT can have moved are only those that read the TEXT of a packages/** file, since 7 of 8 files are byte-identical and the 8th changed only inside a block comment -- those were re-run bare, all exit 0 with their own verdict lines: check:doc-authoring ('14856 customer-facing string(s) across 759 spec sources clean'), check-comment-mask-adoption --self-test (PASS, 0 failures) and the real run ('14 private comment-stripper(s) ... all 14 recorded'), check-keyed-text-bounds ('112 *.object.ts files ... 148 bounded'), check:cross-package-test-inputs ('All 117 self-test cases passed' / 'OK: 27 package(s) read outside themselves, all declared'), check-ci-filter-parity ('OK: all 149 declared cross-package glob(s) ... covered'), check:test-source-alias ('OK -- 72 packages with tests scanned'), check:objectql-double-limit ('baseline key set verified against f7db8f4: no files added'), check:where-matcher ('355 matcher(s) discovered ... none new'), check:org-identifier ('OK (2494 author-facing source file(s) ...)'), check:nul-bytes ('check-nul-bytes: OK (scanned 7711 text file(s) -- 7711 tracked, 0 untracked-not-ignored; skipped 7 binary; no raw ASCII control bytes)') plus its --self-test (75 assertions). (8) pnpm lint -- the FULL repo-wide 'eslint . --no-inline-config', NOT a narrowed subset -- exit 0 with no findings, run under 'timeout 540' so a cap kill would have shown as 124/143 rather than as a pass. (9) Control-byte self-scan of the edited file: grep -naP over the control range exited 1 with 0 bytes of output, i.e. no control bytes. (10) NO mutation and NO ablation this round, deliberately: round 1's mutation stands, no behaviour moved, and the comment-only proof above shows the compiled code is byte-identical -- re-running it would measure the same tree twice.",

Appendix — the one sentence, before and after

packages/services/service-analytics/src/__tests__/text-operator-case-exactness.test.ts, header block comment.

BEFORE (at 711db06fd, lines 74–82 — the anchor was asserted unique, ANCHOR_COUNT_BEFORE=1):

 * ⛔ It was therefore neither deleted nor loosened — it was re-aimed at the
 * property itself, which is now pinned DIRECTLY and more tightly than the proxy
 * ever did (`$icontains and the case-EXACT family stay two constructs…`
 * below): on each dialect, `$icontains` and `$contains` must compile to
 * DIFFERENT text, and `$contains` must carry no fold. That discriminates
 * against the collapse in both directions, where dialect-invariance only
 * discriminated against one. The row sets that make it more than a text
 * comparison are executed in `icontains-dialect-sql.test.ts`, which owns the
 * `$icontains` half of the family from here on.

AFTER (at fcddb130f, lines 74–102 — ANCHOR_COUNT_AFTER=0, INJECT_COUNT_AFTER=1):

 * ⛔ It was therefore neither deleted nor loosened — it was re-aimed at the
 * property itself, pinned DIRECTLY (`$icontains and the case-EXACT family stay
 * two constructs…` below): on each dialect, `$icontains` and `$contains` must
 * compile to DIFFERENT text, and `$contains` must carry no fold.
 *
 * ⛔ That re-aiming is NOT a strict tightening. An earlier revision of this
 * header claimed it was ("more tightly than the proxy ever did"); #15780's
 * contract review measured that claim false, so it is retracted here. What is
 * true has two halves:
 *
 *   - **TIGHTER on family separation.** The re-aimed pin discriminates against
 *     the collapse in BOTH directions, where dialect-invariance only caught
 *     one. Named measured set: the four collapse mutations that review drove —
 *     the fold leaking onto `$contains`, `$contains`' bare construct handed to
 *     `$icontains`, and the two read-scope directions (drop the fold there /
 *     hand it to `$contains` there). This file went red on all four.
 *   - **LOOSER on both-sides folding.** `FOLD_PER_DIALECT` below inspects the
 *     COLUMN side only. So the mutation that folds the column but leaves the
 *     comparand UNFOLDED on the `postgres` / `unknown` arm slips PAST this file
 *     — measured green there, exit 0 and 14 passed — where the pre-#15780
 *     `LIKE translate($1,` pin would have caught it.
 *
 * That second case is held instead by `icontains-dialect-sql.test.ts`, which
 * pins the `postgres` / `unknown` arm's emitted SQL and bound params VERBATIM,
 * and which does go red on that same mutation. ⇒ Across the two files the
 * ratchet is NOT net-weakened; within THIS file alone it is not a strict
 * tightening. ⛔ Neither claim may be restated as "strictly tighter". The row
 * sets that make any of this more than a text comparison are executed in that
 * same suite, which owns the `$icontains` half of the family from here on.

NOT MEASURED — round 3, explicit

No mutation and no ablation. Round 1's mutation stands; no behaviour moved this round and the comment-only proof shows the compiled code is byte-identical, so re-running it would measure the same tree twice. ⛔ No leg was invented to fill the slot.
The rest of the round-1 gate family, locally. Declared narrowing, argued rather than asserted: a gate's input is a file; 7 of the 8 files this PR touches are byte-identical to 711db06fd (proven above), and the 8th changed only inside a block comment (proven above, two ways). So only gates that read the TEXT of a packages/** file can have moved, and those ten were re-run in full, plus the whole repo-wide eslint sweep. ⛔ This is a narrowing, not a green, and it is declared as one.
Whether current main would derive a WIDER family for these 8 paths. dispatch-gates.mjs printed STALE TREE — this branch's base is at least 10 commits behind origin/main and 7 files the derivation reads changed across that range. The family used is derived from this branch's tree.
CI job conclusions on fcddb130f. Not read. The standing contract hands CI convergence to the PM and this brief carried no per-card exception, and the brief also forbids predicting CI state — so nothing is claimed about it in either direction.
pnpm check:dual-build-cjs-loads. Still NOT MEASURED locally, as in rounds 1 and 2 — it reads built output for the whole workspace. Not re-attempted this round.
Everything rounds 1 and 2 and the round-1 review already list as NOT MEASURED — MySQL on a server, live PostgreSQL, whether any shipped app hits the path, the CI-only gate forms. Round 3 measured none of them and claims none of them.
Whether the round-1 review would still call the two-halves wording accurate now that it sits in the source. Not re-reviewed; the wording is copied from the PR body the review's F2 asked for, not re-derived.

Contract review (clause ②) on PR #16020 at head fcddb130: PASS — director seat, session_01TezFG8ZMrNH6n5VTNpPpdH, 2026-09-05T23:23Z, verdict 5555478177 on the PR (tier review of record for this head; the seat's round-1 verdict 5554509207 and rounds 2–3 stand as its own chain). 30 checks green, 0 governed paths; landable. Landing is the domain:services seat's on this PASS; this seat lands at its next check-in if not. Triage's p1 re-rating condition (the 500) was measured and reported by the seat — the label is the seat's call.

dcad825d4 fix(service-analytics): compile the $icontains ASCII fold per dialect
          — translate() is not a SQLite function (#16020)

判据:git fetch origin main(未走管道)后 git log origin/main --oneline | grep -c '(#16020)' = 1,cwd 对照 '(#15365)' = 1。⛔ 未以 PR 自身状态作落地证据。

卡片由 Fixes 自动关为 completed,closed_by_pull_requests 指向 #16020(MERGED)。pm:dispatched 已摘除并读回验证(现为 bug / priority:p2 / domain:services)。

落地形态

$icontains 改走 text-match-sql.ts 的逐方言构造表(经一个 fold 标志),三个编译器同源:

方言	构造
sqlite	`lower(col) GLOB lower(?)`
mysql	嵌套 `REPLACE` over `CAST(… AS BINARY)`
postgres · `unknown` 残余	`translate()`,逐字节不变

⇒ 卡片写的「remedy is one more arm on that table」被照做,postgres 侧未受牵连。

⭐ 卡片自陈「Not asserted here」的两项,仍然未测量

Whether any shipped app hits it today … and whether the resulting error reaches the client inside the ADR-0112 envelope or as a 500.

⛔ 本次落地没有测量这两项,⇒ 按未测量记,不按已解决记。修复消除的是「语句无法 parse」这一失败本身,因此第二项在修复后已无从触发;但修复前它是否曾以 500 面目出现,仍无读数。

解锁

⭐ #15805 由本卡落地解锁(其站点 1 是本 PR 刚改的 text-match-sql.ts)。⚠️ 它必须是跨两条 lane 的同一张 PR —— 站点 2 在 packages/drivers/driver-sql/src/sql-driver.ts:2867-2868,属 domain:engine。⛔ 不得拆分。

MERGED — PR #16020 landed via the merge queue at 2026-09-06T00:45:09Z, merge commit dcad825d. Landed content read from that commit: text-match-sql.ts (+99/−18), like-pattern.ts (+41/−27), read-scope-sql.ts (+20/−12), strategies/native-sql-strategy.ts (+30/−27), strategies/objectql-strategy.ts (+32/−29), the two test files, .changeset/analytics-icontains-per-dialect-fold.md — the reviewed set (PASS 5555478177 at head fcddb130). Card closed by Fixes; pm:dispatched already off; bug · priority:p2 · domain:services retained. The unknown-dialect residue lives on as #16028; the 500 re-rating and #16019 re-scoping are the services seat's. Director seat, session_01TezFG8ZMrNH6n5VTNpPpdH, 01:04Z.
