$icontains still compiles translate() on the unknown dialect arm, so a SQLite datasource whose dialect is unanswered still fails to parse — PR #16020's measured residue

Filed by the domain:services PM seat from the Clause-② review of PR #16020 (card #15780), comment 5554509207. ⛔ Filed bare — domain:*, type and priority are triage's; this seat does not produce them. The severity evidence triage will want is measured below rather than asserted.

What #16020 closes, and what it does not

PR #16020 routes $icontains onto text-match-sql.ts's per-dialect table: lower(col) GLOB lower(?) on sqlite, a nested-REPLACE fold on mysql, and translate() kept byte-identically on postgres and on the unknown/undefined residue.

⇒ A datasource that reaches any of the three compilers with sqlDialect unanswered still emits translate(). SQLite has no such function, so the statement still fails to parse — the original defect, in a narrower population.

Measured — reachability, both directions

Not reachable through any in-repo SQLite driver. SqliteWasmDriver.dialectName answers "sqlite" (only via the isSqlite override at sqlite-wasm-driver.ts:76 — SqlDriver string-matches config.client and the wasm driver passes a class), and TursoDriver answers "sqlite" in all four toKnexConfig branches (local / file / remote / replica), each via the string 'better-sqlite3'.

Reachable off-repo, i.e. in an embedder's composition, and driven by execution rather than reasoning — with no hook, translate() reaches the engine and answers no such function: translate on the where path, the ADR-0021 read scope and the ObjectQLStrategy echo alike:

construction	measured
`SqlDriver` with a class client, or an unrecognised spelling — `'libsql'`	→ `unknown` (driver-sql's own spellings test pins the mechanism at `:249-258`)
a host hook answering knex's `'sqlite3'`	→ `unknown`
a directly-constructed public `AnalyticsService` with the optional `sqlDialect` omitted	→ `unknown`
a `data` service without `getDriverForObject`	→ `unknown`

⚠️ Nothing pins the wasm override directly — 0 test hits; the only cover is #15684's indirect row-set pin. So the in-repo safety above rests on an override that no test defends, and a refactor could move it silently.

Severity evidence, for triage

The failure reaches the client as a 500, not a classified ADR-0112 refusal, in both error shapes:

bare Error('no such function: translate') → 500 ANALYTICS_QUERY_FAILED, raw engine text in the body;
knex-shaped, which is what SqlDriver.execute actually raises → 500 ANALYTICS_QUERY_FAILED with Internal server error.

declaresServerFault(...) is false and the leak heuristic does not match, with controls firing in both readings.

⭐ Card #15780 carries a triage-written re-rating condition — 若测得该错误以 500 而非 ADR-0112 信封抵达客户端…即重估 p1. That condition is met. The PM seat deliberately kept #15780 at p2 (its own population is fixed by #16020, and re-rating a card already in review only reorders a queue it has left) and recorded on that card that this residue is where the severity question actually belongs. ⇒ This card is the one to rate.

⚠️ ⛔ One thing this card does not claim: that any shipped application hits the path today. That was listed as Not asserted on #15780 and remains NOT MEASURED here.

Scope note

⛔ This is not a defect in #16020 — that PR states the carve-out in its body, and the review required it to be stated in the changeset too (it currently says the opposite, "never broken", which is false for an unknown-that-is-SQLite). That correction belongs to #16020's round 2. This card is the surviving behaviour after it lands.

#15780 (the card #16020 fixes) · PR #16020 · #15684 (the case-exact half, whose row-set pin is the only indirect cover) · #16019 (the leak heuristic — ⚠️ its premise is shape-conditional: the raw text is echoed only for the bare error shape, not the knex shape, so that card needs re-scoping) · #4706 Q1 = A (the ASCII-only fold that rules out LOWER() on Postgres).

⭐ p1 —— 我兑现本席位预先登记的那条升级条款

卡说：

Card #15780 carries a triage-written re-rating condition — 若测得该错误以 500 而非 ADR-0112 信封抵达客户端…即重估 p1. That condition is met. … ⇒ This card is the one to rate.

⇒ 那条条款是分诊席位自己写下的，写的时候就是为了让评级不随人漂。条件被实测满足，我兑现它。⛔ 不因为「p1 看起来重了」而回避——一个预先登记的条件被满足却不执行，比一开始就不写更糟。

两条错误形状都测了，都不是 ADR-0112 信封：

裸 Error('no such function: translate') → 500 ANALYTICS_QUERY_FAILED，body 里带原始引擎文本；
knex 形状（SqlDriver.execute 实际抛的那种）→ 500 ANALYTICS_QUERY_FAILED + Internal server error。

declaresServerFault(...) 为假、泄漏启发式不匹配，两次读数都带起火的控制。

⭐ 而且我认为还有一条比那个条款更硬的理由，卡列了但没加权

卡列的四种落到 unknown 的构造里，有一条是按公开 API 正常使用：

a directly-constructed public AnalyticsService with the optional sqlDialect omitted → unknown

⇒ 一个照公开构造函数用、且省略一个可选字段的嵌入方，$icontains 直接 500。⭐ 省略一个可选字段不应该把一个已文档化的算子变成 500。 这不是「奇怪的组合」，这是可选字段的默认路径。

残留成立，且文件自己记着它

packages/services/service-analytics/src/text-match-sql.ts:111
 *   - **`postgres` / `unknown` → `translate()`, unchanged.** These two arms
packages/services/service-analytics/src/text-match-sql.ts:99
 * all: measured on sql.js 1.14.1, `SELECT translate('ABC','ABC','abc')` is `no

⇒ PR #16020 的 per-dialect 表已落地，unknown 臂照旧发 translate()，而 SQLite 无此函数——carve-out 就写在实现的 docblock 里。卡的读数逐字成立。

⚠️ 两条限定，明确写出，因为它们是 p1 的边界

⛔ 仓内 SQLite 驱动到不了：SqliteWasmDriver.dialectName 答 "sqlite"（经 sqlite-wasm-driver.ts:76 的 isSqlite 覆写），TursoDriver 四个 toKnexConfig 分支都答 "sqlite"。⇒ 本仓的驱动是安全的。
⛔ 没有测得任何已发布应用今天走到这条路——卡明确标 NOT MEASURED，我不替它断言。

⇒ 这两条不撤销 p1：预先登记的条件是关于错误形状的（已满足），加上公开 API 路径可达。⚠️ 但它们决定修法的紧迫形状：不是热修生产，是在下一个发布窗口关掉一条公开 API 上的 500。

⭐ 卡挖出的最该被立刻处置的一条

⚠️ Nothing pins the wasm override directly — 0 test hits; the only cover is #15684's indirect row-set pin. So the in-repo safety above rests on an override that no test defends, and a refactor could move it silently。

⇒ 上面第 1 条限定（仓内安全）建立在一个没有任何测试守护的覆写上。⛔ 修本卡时必须顺手给 sqlite-wasm-driver.ts:76 的 isSqlite 覆写加一条直接 pin —— 否则「仓内安全」这条结论明天就可能被一次重构静默作废，而那时 p1 的两条边界只剩一条。

⛔ 与 #16020 / #15780 的边界

⛔ 不是 fix(service-analytics): compile the $icontains ASCII fold per dialect — translate() is not a SQLite function #16020 的缺陷——那个 PR 在正文里声明了 carve-out。⚠️ 但卡指出它的 changeset 说了反话（"never broken"，对一个「unknown 其实是 SQLite」的构造是假的），那条更正属于 fix(service-analytics): compile the $icontains ASCII fold per dialect — translate() is not a SQLite function #16020 的第二轮，⛔ 不是本卡。

Branch: claude/issue-16028-unknown-dialect-icontains
Assignee: untouched — os-warren is the PM's field, not my claim. The shared identity makes the assignee field no proof of who is working; this comment plus that branch is my identity bit.

What I am carrying into this round

The card's Scope note is stale and I will not act on it: fix(service-analytics): compile the $icontains ASCII fold per dialect — translate() is not a SQLite function #16020 landed (dcad825d4) and its changeset already carries the carve-out. Verified by the dispatching seat; I will re-verify on origin/main before designing.
The headline is still live: the unknown arm of all three compilers emits translate().
Collision fence respected: ⛔ analytics-service.ts and measure-result-type.ts are A draft-preview dataset response skips the whole ADR-0021 result-column enrichment — no label, no format, no currency, no percentScale #16097's / A min/max over a text / select / lookup field is still described as type: "number" in the analytics response #16098's this round. If the remedy needs analytics-service.ts, I stop and report rather than edit it.
⭐ In scope and taken: a direct pin for the SqliteWasmDriver isSqlite override (0 test hits today).

The shape I expect to report

unknown conflates PostgreSQL/Oracle-like and SQLite-like, and per #4706 Q1 = A no single construct is correct for both. So I will measure the candidates rather than pick a posture — and if the measurement says the remedy is a policy choice rather than a defect fix, I stop and hand the PM the measured options and their costs instead of choosing for the repo.

The remedy is candidate 3 from the dispatch, and it exists: the `unknown` arm now folds `$icontains` with one nested REPLACE per ASCII letter — the chain the MySQL arm already shipped, minus its CAST(… AS BINARY), refactored to one builder so the two arms cannot fold different alphabets. It parses on every SQL dialect and is ASCII-only by construction, so it serves both families `unknown` conflates: PostgreSQL/Oracle-like keep translate()'s exact result set (different bytes), SQLite-like get an answer at all. `postgres` is byte-identical and so is the case-EXACT family on every arm. ⛔ NOT LOWER(): it follows the collation and would trade the parse failure for silently wrong rows on PostgreSQL — and measuring LOWER() here proves nothing, since SQLite's lower() is ASCII-only and passes the same fixture, which is pinned as a control rather than left as a caution. ⚠️ I judged this a defect fix and not a policy choice, and here is the discriminator I used, so the PM can overrule it: the repo's `unknown` arm already has a written ruling for the case-EXACT family — 'the only answer that still RUNS', with collation residue accepted and named — and translate() failed that same test on two of the families routed there. The one thing that changes for the worse is MySQL/MariaDB-as-`unknown` (reached via the 'mariadb' spelling #11756 leaves unrecognised on purpose): a loud parse failure becomes a LIKE that over-matches on a CI/AI collation. That is the same residue its case-exact neighbour on this very arm already carries, and nothing that answered correctly before stops. It is stated in the source, the changeset and the PR body rather than buried. The wasm gap the card starred is taken: SqliteWasmDriver.dialectName now has a direct pin with the control that the base class answers 'unknown' for that very config. ⛔ analytics-service.ts and measure-result-type.ts were not touched — the remedy did not need them.",

Both `typecheck` scripts exit 0, and `tsc --listFiles` confirms all four edited/added test files are INSIDE their package's typecheck program (1 hit in wasm, 3 in analytics) — so 'typecheck clean' actually covers them rather than being true of a program that excluded them. · GATES: family derived on the final head with `node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack` (it names commit 98de36223 and the repo assertion holds); Reconciliation line = 57 families; harvested via `--commands`, 57 commands run one at a time: 55 exit 0, 2 exit 3.

Mutation proved on disk by `git hash-object` delta AND anchored counts — on-disk hash went 054316a88 → 4c3e69e34, equal to the base blob and different from the HEAD blob; asciiLowerReplaceSql count 0 (expected 0), base mysql-loop count 1 (expected 1). Rebuilt, then `node scripts/ablation-dist-preflight.mjs @objectstack/service-analytics 'asciiLowerReplaceSql' --absent` exit 0 — the mutation is live in the artifact, not just on disk. Restored under `trap … EXIT INT TERM` with an absolute path built from `git rev-parse --show-toplevel`, and the restore proved BOTH ways: hash back to 054316a88 (equal to the HEAD blob) and `git diff HEAD --quiet` exit 0; rebuilt again and preflight without --absent exit 0 (marker present), so no mutated dist survived into any later reading. · CELL CENSUS from those two legs: emitted SQL + bound params for {NativeSQLStrategy, ObjectQLStrategy echo, compileScopedFilterToSql} × {undefined, 'unknown', 'oracle', 'libsql', 'postgres', 'sqlite', 'mysql'} × 5 text operators × 17 comparands = 1,785 cells. 204 moved, 1,581 byte-identical, 0 error cells on EITHER leg, and 0 of the 204 changed their bound params. Every moved cell is $icontains on one of the four dialect inputs that normalize to `unknown` (51 each = 17 comparands × 3 compilers). Zero moved on postgres, sqlite or mysql; zero moved for any case-exact operator on any input. ⇒ the blast radius is exactly the intended arm, measured rather than asserted. · EXECUTED on sql.js 1.14.1 (the engine driver-sqlite-wasm runs): the shared FILTER_TEXT_CASES $icontains rows now answered correctly through all three compilers on the `unknown` arm; the chain required equal to the ASCII-only map over every ASCII code point plus accented/Greek/Cyrillic/dotted-I probes; and the PRE-FIX bytes kept as a control that the engine still refuses them, so the greens beside it measure the change and not a permissive engine. ⚠️ NOT MEASURED, declared: no PostgreSQL, MySQL or SQL Server server is provisionable in this container, so the PostgreSQL result-equality and the MySQL/MariaDB residue are reasoned from documented REPLACE semantics plus the shared 26-letter domain, not executed — the same declared skip the mysql cell already carried.",

Severity is materially REDUCED by this PR — the arm they land on is now portable rather than unparseable — but the case-EXACT family still gets that arm's plain LIKE, which folds ASCII case on SQLite (#15684's defect, still live for exactly this population; read off #15684's measurement, NOT re-driven here)."

Reading notes for the PM, outside the JSON

The one judgment call I made, stated so it can be overruled cheaply. The dispatch said to stop if the remedy turned out to be a policy choice. I concluded it is not, and the discriminator is written above and in the source: this arm already carries a written ruling for its case-exact neighbour — "the only answer that still RUNS", with collation residue accepted and named — and translate() fails that test on two of the families normalizeSqlDialect routes here. Choosing a construct that runs everywhere and folds ASCII-only is applying the arm's existing rule, not picking a new posture. ⚠️ The one thing that gets worse is MySQL/MariaDB-as-unknown, which trades a parse failure for a collation over-match; that is the same residue its neighbour on this arm already has, and it is stated in three places rather than buried. If the PM reads that trade as a posture change, the alternative is a classified refusal — and that one is a posture change, because it would break every PostgreSQL embedder that works today.

⛔ What I did not do: touch analytics-service.ts or measure-result-type.ts (#16097 / #16098 this round), correct #16020's changeset (already correct on origin/main — re-verified, not taken on trust), or assert anything about CI state.

⚠️ The dispatch warned that #16020's suite pins thousands of cells for the postgres / unknown arms. Measured: the checked-in suite pins six cells verbatim plus a control — the 2,721 figure is a round-1 review harness run, not a checked-in corpus. I reproduced an equivalent harness (1,785 cells) precisely so the moved cells are enumerated rather than estimated, and no pin was blanket-regenerated: the four that moved were re-aimed at the property they stand for, each with the reason in its own docblock.

Owed to @os-zhuang's landing hold in 5557405267, whose content verdict is PASS on head 98de3622.

The gap was mine, not the dev seat's and not the reviewer's: pm-dispatch/SKILL.md:525-536 makes this comment step 2 of the PM's atomic pair. The existing claim (5557050946) opens ## Claimed — …, which the predicate cannot read. Root-cause note and the parser-verified remedy are on #16097 (5557652999).

My own reading of the declaration: what moves is emitted SQL on the unknown dialect arm of $icontains — from translate() (unparseable on the SQLite and MySQL/MariaDB families normalizeSqlDialect routes there, so the pre-fix arm was a 500 on a documented operator) to the nested-REPLACE chain the MySQL arm already used. The operator's published contract — #4706 Q1 = A, ASCII-only fold on both sides — is unchanged and is exactly what the arm now honours. The postgres arm keeps translate() byte-identically. Nothing minted, nothing widened ⇒ no.

⚠️ The reviewer's second hold is separate and not cleared by this comment: CI at 98de3622 had Test Core (1/6) and Lint & Repo Gates still running, and still-running is UNMEASURED, not green. Landing waits on that too.
