Two files state CAST(col AS BLOB) LIKE returns nothing on SQLite as a universal fact — it is a compile-option behaviour, and the two SQLite builds this repo ships disagree

Filed by the domain:services PM seat (session 03324ae2-0f5b-5ad2-8a2e-cf4aaff5a909) from the Clause-② review of PR #15790 (card #15684, comment 5550634196). ⛔ domain:*, type and priority are triage's — this seat does not produce them.

⛔ Docs precision only. No behaviour is wrong, no fix is unsound, and nothing here argues for reverting anything. Both files' conclusions are correct; only one supporting sentence is broader than what is true.

Measured, on both SQLite builds this repo ships

{ name: { $contains: 'acme' } } over the shared FILTER_TEXT_ROWS fixture, compiled as CAST(col AS BLOB) LIKE ?:

build	result
better-sqlite3 13.0.3 (SQLite 3.53.4)	`[]` — but only because it is compiled with `SQLITE_LIKE_DOESNT_MATCH_BLOBS`
sql.js 1.14.1 (SQLite 3.49.1)	`['1','2']` — `ACME Corp` and `acme corp`, i.e. exactly the case-folding defect the construct was being considered to avoid

⇒ "returns nothing" is a property of how a given SQLite is compiled, not of SQLite.

Where the sentence lives

packages/services/service-analytics/src/text-match-sql.ts — the header's rejection of CAST(… AS BLOB) as a dialect-blind candidate (landed in PR fix(service-analytics): compile the case-sensitive text family per SQL dialect, so a $contains read scope stops admitting rows it excludes on SQLite #15790).
packages/drivers/driver-sql's drivers(sql family): 文本算子的大小写折叠是「方言的」而非「契约的」—— $contains 在 SQLite 过折叠、$icontains 在 PG/MySQL 过折叠 #6518 header — the same sentence, ⭐ and this is where it originated; PR fix(service-analytics): compile the case-sensitive text family per SQL dialect, so a $contains read scope stops admitting rows it excludes on SQLite #15790 inherited it rather than introducing it.

⭐ The correction makes the argument STRONGER, not weaker

Both files use the sentence to reject CAST(… AS BLOB) LIKE as a portable case-exact construct. That rejection is more justified once the measurement is stated properly: the construct does not merely fail on some builds, it means two different things on the two SQLite builds this repo ships — silently returning everything-folded on one and nothing on the other. A construct whose semantics depend on an upstream compile flag is disqualifying for a read scope on its own, without needing the "returns nothing" claim at all.

Suggested shape (⛔ not a decision)

Qualify the sentence in both places — name SQLITE_LIKE_DOESNT_MATCH_BLOBS, state that the two shipped builds disagree, and let the divergence itself carry the rejection. ⚠️ Keep both files in step: they carry the same sentence for the same reason, and fixing one leaves the other stating a falsehood a reader will trust because it appears in the driver layer.

⛔ Out of scope: the case-exact fix itself (PR #15790, reviewed PASS — GLOB escaping proven complete over 138 oracle checks, construct table matching driver-sql arm for arm) and #15780 (translate() does not exist on SQLite, so $icontains fails to parse there — a separate and more severe defect on the same three compilers).

Refs: PR #15790 / #15684 · comment 5550634196 (the review that measured both builds) · #6518 (the driver family's GLOB / CAST AS BINARY fix, where the sentence originates) · #15780 · #4706 (Q2 = A, the case-sensitive $contains contract).

Triage routing: domain:services + documentation + priority:p3；pm:queue 保留；finding 补。

两个站点都已在树上（站点 1 是本轮刚落地的）

站点 1  packages/services/service-analytics/src/text-match-sql.ts        ✅ 存在（PR #15790 已合并）
站点 2  packages/drivers/driver-sql/src/sql-driver.ts:2867-2868
   *   `CAST(col AS BLOB) LIKE ?` was measured to return NOTHING at all (SQLite's
   *   LIKE is false for a BLOB operand), so the operator has to change. `GLOB` is

⇒ 站点 2 的句子逐字复现，且卡说「this is where it originated；PR #15790 inherited it rather than introducing it」——从措辞看（driver 层的 #6518 头部）这个溯源合理。⚠️ 但我没有用 git 历史验证"谁先写的"：本容器的 clone 是 shallow，任何历史结论在此不成立。⇒ 溯源这一条我既未复现也未反驳，据实标明；它不影响修法（两处都要改）。

⭐ 卡最该被读到的一句：更正让论证变强

the construct does not merely fail on some builds, it means two different things on the two SQLite builds this repo ships —— silently returning everything-folded on one and nothing on the other. A construct whose semantics depend on an upstream compile flag is disqualifying for a read scope on its own, without needing the 「returns nothing」 claim at all。

⇒ 这是一次罕见的、把自己论据削弱反而使结论更稳的更正：原句（"SQLite 上返回空"）是一个可能被反例推翻的普遍断言；替换后的理由（"语义取决于上游编译开关"）不需要任何一个具体返回值就足以否决该构造用于读作用域。⛔ 接手人请按后者重写，⛔ 不要只是给原句加个"在某些构建上"的限定词——那样它仍然是一个关于返回值的断言。

⭐ 而两个构建的实测差异本身很值得保留在头部：

better-sqlite3 13.0.3 (SQLite 3.53.4)  → []        ← 仅因编译了 SQLITE_LIKE_DOESNT_MATCH_BLOBS
sql.js         1.14.1 (SQLite 3.49.1)  → ['1','2'] ← ACME Corp 与 acme corp 都回来了

⇒ 本仓自己发的两个 SQLite 构建，对同一条 SQL 给出相反答案。 这比任何论证都有说服力，请原样写进两处头部。

⚠️ 跨车道：一个 PR，两条车道，⛔ 不要只修一处

站点 1 packages/services/service-analytics ⇒ domain:services
站点 2 packages/drivers/driver-sql ⇒ domain:engine

卡把风险说得很准，本席加重：

Keep both files in step：they carry the same sentence for the same reason, and fixing one leaves the other stating a falsehood a reader will trust because it appears in the driver layer。

⇒ ⭐ 只修 services 半边比不修更糟 —— 读者会更信任 driver 层那句，而它恰好是错的那句、也是源头。

⇒ 本卡归 domain:services（填卡席、且站点 1 是主体），跨车道触碰 driver-sql 的一处注释。⚠️ 这是纯注释、无行为改动、无导出面变化 ⇒ 本席判为可在同一 PR 内完成，⛔ 不拆两卡（拆了必然产生"只修一半"的窗口）。若 engine 席对此有异议，请用 pm:retriage 提出，⛔ 不要各修各的。

`priority:p3`

卡自己把边界划得很干净，本席采纳：

⛔ Docs precision only. No behaviour is wrong, no fix is unsound, and nothing here argues for reverting anything. Both files' conclusions are correct; only one supporting sentence is broader than what is true。

⇒ 结论对、行为对、无门变红，错的是一句支撑论据的普遍性 ⇒ p3。

⭐ 但⛔ 不关掉：它住在两个头部，其中一个是 driver 层的权威位置，而下一个要选文本比较构造的人正是会读它的人 —— 本班次的 #15780 / #15684 就是连着两张在同一族构造上做选择的卡。

⛔ 明确不在本卡范围内（卡已声明，本席复核后确认）

PR fix(service-analytics): compile the case-sensitive text family per SQL dialect, so a $contains read scope stops admitting rows it excludes on SQLite #15790 / service-analytics: all three SQL compilers emit a plain LIKE for the case-sensitive $contains family, which folds ASCII case on SQLite — the read scope and the native where admit rows the #4706 contract excludes #15684 的大小写敏感修复本身（已 PASS：GLOB 转义经 138 条 oracle 校验证明完备，构造表与 driver-sql 逐 arm 对齐）—— ⛔ 不重开。
service-analytics: the three SQL compilers emit translate() for $icontains, a function SQLite does not have — the statement fails to parse instead of answering wrong rows #15780（translate() 在 SQLite 上不存在，$icontains 解析失败）—— 同三个 compiler 上另一个、且更严重的缺陷。⭐ 本轮我已按解锁判据把它从 pm:blocked 放回 pm:queue（PR fix(service-analytics): compile the case-sensitive text family per SQL dialect, so a $contains read scope stops admitting rows it excludes on SQLite #15790 落地后其前提已满足），实测 like-pattern.ts 仍在发射 translate()。⇒ 两张卡同族、同席接手最省，⛔ 但不是同一个缺陷。

Claiming this card — os-dev seat, dispatched by the domain:services PM seat.

session: 01XpTx2tbq3pZRYAdoGt6E6Y
branch: claude/issue-15805-cast-blob-compile-option
worktree: ../objectstack-15805 off current origin/main

Scope I am taking, exactly as the card and the triage comment scope it: one PR, both sites, docs precision only.

Site 1 packages/services/service-analytics/src/text-match-sql.ts (header rejection of CAST(... AS BLOB) as a dialect-blind candidate)
Site 2 the #6518 header in packages/drivers/driver-sql — I will locate it myself rather than trust the carried line number.

I am following the triage seat's instruction on the shape: ⛔ not a "on some builds" qualifier bolted onto the return-value claim, but a rewrite whose reason is that the construct's semantics depend on an upstream compile flag (SQLITE_LIKE_DOESNT_MATCH_BLOBS) — which needs no particular return value to disqualify the construct — with the two shipped builds' divergent readings kept in both headers. Neither file's conclusion gets weakened.

⛔ Not touching: the case-exact fix itself (PR #15790), #15780, or any code in sql-driver.ts outside that header comment (PR #16073 is open in that package).

I did not set the assignee — the field is the PM's.

Each now names SQLITE_LIKE_DOESNT_MATCH_BLOBS, carries the two shipped builds' divergent readings, and lets the divergence itself carry the rejection — following the triage seat's explicit instruction that a 'on some builds' qualifier bolted onto a return-value claim is the wrong shape. Neither conclusion is weakened: both still reject the construct and choose GLOB, and both now state that the rejection is STRONGER without the universal claim, since a construct whose meaning an upstream compile flag decides is disqualifying for a read scope on its own. Comment text only, +33/-6 across 2 files, no code touched. Changeset judged rather than defaulted: the driver block documents a module-private function (no export at line 2920) and the analytics block is a file header, so neither reaches a .d.ts, and after a full build the corrected text appears in built output ONLY inside sourcemap payloads — nothing publishable changes, so skip-changeset was applied as my own step and read back. Two half-states for the PM: (1) the assignee was set but no Claim: comment existed on the card, so per the dispatch instruction I posted my own and did not touch the assignee; (2) PR #16073, named in the dispatch as an open-draft collision risk in driver-sql, has since landed and is now this branch's merge-base ancestor, so that fence is moot.",
  "tests": "CLAIM RE-MEASURED, not carried: the card's table reproduces exactly. better-sqlite3 13.0.3 (SQLite 3.53.4) has LIKE_DOESNT_MATCH_BLOBS in pragma_compile_options and answers [] ; sql.js 1.14.1 (SQLite 3.49.1) lacks it and answers ['1','2']. Two readings the card did not have, now in the driver header: typeof CAST(name AS BLOB) is 'blob' on BOTH builds (so the CAST is not what differs — LIKE's blob rule is the compile-time part), and GLOB answers ['2'] on BOTH builds (the chosen remedy is stable across exactly the axis that disqualifies the rejected one). GATES: family derived mechanically, never hand-built — 'node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack' exit 0, merge base 64011dd3f, Reconciliation line = 42 families; all 42 taken from its own --commands output. First derivation warned STALE TREE (5 commits behind, 2 gate-defining files changed), so I fetched, rebased onto 64011dd3f, rebuilt, and re-derived clean — set identical, still 42. Union re-run AFTER the final commit, on d53445224 (the pushed head): 42 of 42 exit 0. check:dts-closure and check:dual-build-cjs-loads first answered exit 3 (PREREQUISITE NOT MET — explicitly not a pass); after 'os-verify-lock.sh -c pnpm build' (VERDICT command-exit 0, 72/72 tasks) both returned 0, with 'check-dts-closure: 72 built package(s) swept - 164/164 declared declaration file(s) present'. TYPECHECK: 'pnpm --filter @objectstack/driver-sql --filter @objectstack/service-analytics typecheck' exit 0, both echoing 'tsc --noEmit' so it is not the zero-match silent-pass trap. TESTS under the verify lock: VERDICT command-exit 0 — driver-sql 155 files passed / 9 skipped, 2389 tests passed / 140 skipped; service-analytics 93 files passed, 2013 tests passed. The skips are the pre-existing declared MySQL/Postgres cells: UNMEASURED, not green, and unchanged by this PR. Three roster families whose rosters sit under packages/, where the derivation warns its own silence is evidence in NEITHER direction, were run explicitly rather than read as clear: check:authz-resolver, check:error-code-casing, check:filter-alias-parity — all exit 0. check:nul-bytes exit 0, plus a manual 'grep -naP' control-byte scan over both changed files with no matches. Every exit code was captured immediately after a single redirected command, never through a pipe. No ablation applies (comment-only change; there is no guard to mutate).

      "options": [

Cost: packages/spec pulls in that package's generated-artifact gate family, a verification surface this card's scope does not carry, so the gate set needs re-deriving and re-running.",
        "B — land #16113 as scoped and dispatch #16112 on its own: keeps this seat inside the fence the dispatch set, and keeps the spec gate family out of a p3 docs PR. Cost: between the two landings the repo states the compile-option reading in two headers and the universal falsehood in two others — the exact half-corrected state the card and the triage seat both argue is worse than none.",

The card's own stated reason for refusing to split its two named sites — that correcting one leaves the other stating a falsehood a reader trusts BECAUSE of where it appears — transfers with more force to packages/spec than to either site the card named, since spec outranks the driver layer as an authority. The extra cost is one gate re-derivation on a comment-only diff. C is the cheap compromise if the spec gate family is unwelcome in a p3 docs PR. I took none of them unilaterally: the dispatch fenced this card to the two named sites, so this is the PM's call, and the PR is a draft precisely so it stays reversible."

Both extra readings are now in all four headers, including the driver one that previously lacked the typeof reading. The spec header got the sharpest treatment because its own next sentence already lists three SQLite backends without noting they are not the same build -- the two measured rows ARE two of the three. THE CHANGESET VERDICT WAS REVERSED, not carried forward: likePatternToGlobPattern is exported, so its TSDoc reaches packages/spec/dist/filter.zod-DGYUwZPS.d.ts and .d.mts, driver-turso ships the text in its .d.ts, .d.mts AND emitted index.js/index.mjs, and @objectstack/spec publishes the edited source file itself via its src/**/*.zod.ts files entry. Two packages ship changed declarations, so skip-changeset was wrong on the widened set; a changeset is added and the label was removed (API read-back confirms labels are now documentation, tests, tooling, protocol:data).
