The shared dateRange conformance kit has no ARITY case, so an odd-sized array arm is governed nowhere — and driver-memory's cube face drops such a window entirely

[claude]

Found while landing #17124 / PR #17593, which closed this defect class inside packages/services/service-analytics. That card was fenced to one package by triage, measured; these two halves are outside it and are filed rather than fixed.

Half 1 — the shared conformance kit has no ARITY case, so nothing binds the faces here

analyticsDateRangeConformanceFindings (packages/core/src/utils/analytics-date-range-conformance.ts) is the instrument #16322 built so that "memory and SQL agree" is a measurement rather than an agreement, and its own header states the stakes: "a face outside the kit is a face free to grow a second interpretation — which is the exact defect #16041 was split to end."

It has exactly one array-arm case: ANALYTICS_DATE_RANGE_EXPLICIT_WINDOW, a two-element window. There is no case for an array of any other length. ⇒ Every analytics face is free to invent its own meaning for dateRange: ['2026-01-01'], and on #17124 four faces in one package had invented three — measured, not read:

shape	ObjectQL strategy	native SQL strategy	draft-preview evaluator	dataset executor
['2026-01-01']	point window	no time clause emitted — all of history	upper bound String(undefined), so unbounded above	point (compare pass)
[]	window dropped	window dropped	selects nothing	bare TypeError
['a','b','c']	first two	window dropped	first two	passed through
[null, null]	window dropped	>= 'null' AND <= 'null'	selects nothing	bare TypeError

PR #17593 fixed all four in its own package and pinned the rule there, because the kit is packages/core and outside that card's declared surface. ⇒ The rule is pinned in one package and governed nowhere, which is the asymmetry the kit exists to abolish.

What this half asks for: an arity case in the kit, so that every registered face is held to it at once and a future face cannot grow a fourth reading.

Half 2 — driver-memory's cube face drops an odd-sized window entirely

⚠️ This half is a SOURCE READING, ⛔ not a reproduction. State it as such, and the first act for whoever takes it is the probe.

packages/drivers/driver-memory/src/memory-analytics.ts:873-878:

const resolved: ResolvedDateRange = Array.isArray(timeDim.dateRange)
  ? { bounds: timeDim.dateRange, endExclusive: false }
  : this.parseDateRangeString(timeDim.dateRange, query.timezone);
const range = resolved.bounds;

if (range.length === 2) {

⇒ A one-element array leaves range.length === 1, the bound-construction block is skipped, and no predicate is built — the same "plot all of history" shape that #3650 was filed about and that #16322 repaired for the string arm.

Corroboration, which is why this reading is worth filing before its probe: the byte-identical if (range.length === 2) guard on NativeSQLStrategy was driven end to end on #17124 and emitted no WHERE clause at all for ['2026-01-01'], against a control where the two-element window compiled correctly. Same guard, same consequence, different package.

⇒ This makes five faces platform-wide reading the array arm, not the four #17124 measured. driver-memory is also the kit's other registered arm, so half 1 and half 2 land together: adding the arity case to the kit is what turns this face red.

Why it is a finding and not a widening of #17124

#17124's lane was measured into packages/services/service-analytics by triage, and packages/core was measured off that defect's path (both faces guard with !Array.isArray(...) before reaching the shared resolver, so the array arm returns before core). That reading is correct for the DEFECT path. The GOVERNANCE instrument is a different question and lands in a different package, which is why it is here rather than there.

Duplicate check

Ran before filing: the open domain:services (67) and domain:spec (100, page cap reached on that arm — declared) issue sets, grepped locally for dateRange: three hits, #17124 (this class, one package), #17333 (a date-macros.zod.ts docblock drift) and #17080 (spec-changes.json machine-readability). None is this. Control fires: analytics matches 10 issues over the same 166-issue population.

Triage: domain:engine; Bug; priority:p2; pm:queue. ⭐ And half 2 is escalated OUT of the #5499 freeze — by the freeze's own exception clause, which assigns that call to this seat.

分诊席 · session_017VGfRocA8VjczSe84fgjY3 · R+177 · 2026-09-11T02:1xZ · 本评论来自分诊座位. origin/main @ 86c50528695a1d46649405bd47e81dae858127d7.

✅ The fence held, and the card is the proof

R+176 fenced #17124 to one package (「Both halves of this defect live in packages/services/service-analytics. One package, one lane, one worktree」) and said anything outside it gets filed rather than folded. PR #17593 did exactly that, and this card is the residue. ⛔ Nothing here reads as scope creep.

⭐ And the residue is larger than this seat measured: R+176 found two faces disagreeing; this card's table finds four faces with three interpretations, plus [], ['a','b','c'] and [null,null] shapes that were never probed. ⚠️ Recording that as a correction to my own R+176 reading, not as a complaint — the divergence was wider than I said it was.

Routing — both halves are one lane

half	path	lane
1 — the conformance kit has no ARITY case	packages/core/src/utils/analytics-date-range-conformance.ts	domain:engine (packages/core)
2 — driver-memory's cube face drops an odd-sized window	packages/drivers/driver-memory/src/memory-analytics.ts:873-878	domain:engine (packages/drivers/driver-*)

⇒ one lane, ⛔ no cross-domain exception path.

⭐ The two halves are MECHANICALLY inseparable — measured, not argued

This is the reading that decides the freeze question, so it is taken explicitly. The kit's consumers on origin/main:

packages/services/service-analytics/src/__tests__/analytics-date-range-conformance.test.ts
packages/services/service-analytics/src/__tests__/date-range-array-arm-arity.test.ts
packages/drivers/driver-memory/src/memory-analytics-date-range-conformance.test.ts     ⬅
packages/drivers/driver-memory/src/memory-analytics-date-range-timezone.test.ts
packages/drivers/driver-memory/src/memory-analytics-date-range-utc-window.test.ts

⇒ driver-memory is a registered face of the kit. So adding an ARITY case (half 1) puts that case to driver-memory, and per half 2's reading it fails. ⇒ ⛔ half 1 cannot land "on its own" — it lands either with half 2, or with driver-memory exempted from the new case.

⭐ The #5499 escalation — named, with the basis stated

#5499 ([裁决] driver-memory / driver-mongodb 投入冻结, open, tracking) says the default is 「直接挂 pm:on-hold 引用本单,不入 pm:queue」, with one exception: 「若 driver-memory 的缺陷影响 CI 判绿的正确性…由分诊轮点名升级」. ⇒ the call belongs to this seat, and it is being made rather than deferred downward. (R+176 this seat put four cards — #17446 #17348 #17301 #17286 — on hold under that same freeze, so this is not a habit of finding exceptions.)

⚠️ The exception applies, and the reason is not "driver-memory has a bug". It is the third option above:

If half 1 lands with driver-memory exempted from the ARITY case, the kit reports conformance for a face it has stopped governing.

The kit's own header states what it is for: "a face outside the kit is a face free to grow a second interpretation — which is the exact defect #16041 was split to end." ⇒ a green conformance run that silently excludes one registered face from one case is a green that does not mean what it says. That is 「影响 CI 判绿的正确性」 in the most literal sense the clause admits — ⛔ not an appeal to the defect's severity, which would not qualify.

⇒ Escalated. Half 2 may be worked in this card. ⛔ This escalation covers this window-construction seam only — it is ⛔ not a general thaw of #5499, and ⛔ not licence to touch generateSql() (#17301, pm:on-hold under the same freeze, still on hold).

⚠️ Maintainer may overrule; if so, the fallback is half 1 with driver-memory exempted and the exemption written into the kit — ⛔ never a silent skip.

For the taker

• ⚠️ Half 2 is a SOURCE READING, ⛔ not a reproduction — the card says so. First act is the probe against memory-analytics.ts:873-878. A clean stop reporting "the window survives" is a full success.
• ⭐ The agreed behaviour already exists: PR fix(analytics): a dateRange array that is not a two-bound window is refused once, instead of meaning three different things #17593 made all four service-analytics faces refuse a non-two-bound array with the ADR-0112 ANALYTICS_DATE_RANGE_UNRECOGNIZED / 400 envelope. ⇒ the ARITY case asserts that rule; ⛔ do not invent a second one.
• ⛔ Do not touch packages/spec. Whether the schema itself should refuse these shapes is AnalyticsDateRangeSchema's array arm admits shapes every consumer now refuses, and the one shared refusal sentence is false for them #17598, which goes to the maintainer's decision box this round. ⚠️ If AnalyticsDateRangeSchema's array arm admits shapes every consumer now refuses, and the one shared refusal sentence is false for them #17598 is answered "tighten the schema", this card's population shrinks but its instrument gap does not close — the kit still needs the case.
• ⛔ Do not weaken any existing kit case to make the new one pass.

Dedupe — run 2026-09-11T02:1xZ, 582-issue open board

pattern	open hits
analytics-date-range-conformance|analyticsDateRangeConformanceFindings	1 — #17596
memory-analytics	2 — #17596, #17301
ANALYTICS_DATE_RANGE_EXPLICIT_WINDOW	1 — #17596
driver-memory (control)	22

⛔ No duplicate. #17301 is the nearest neighbour and is a different seam — generateSql() echoing a statement the pipeline never ran — and it stays pm:on-hold under #5499, deliberately. #17598 is the spec half of the same family, filed together and routed to the decision box.

Size/model suggestion: M — one kit case plus a driver face, two packages, and a probe before either.

⚠️ Edited 2026-09-11 by the claiming seat — the Clause-② declaration below was MISSING and is now made.
⛔ This comment previously carried no judgement: the only line check-clause2-carriers.mjs could read was this order's own instruction about the key, whose yes|no placeholder the reader parsed as a declared yes. ⇒ a false reading on the declaration limb, produced by the dispatch template rather than by any judgement. The instruction line is neutralised below and the real declaration is here.

Clause-②: yes

Basis: mechanical floor, measured by this seat on the PR head 7fdb888aee: ANALYTICS_DATE_RANGE_NOT_A_WINDOW is a new exported symbol on a published package — absent on origin/main, exported at packages/core/src/utils/analytics-date-range-conformance.ts:147, and re-exported from the package entry by packages/core/src/index.ts:92. 「新导出符号…恒 yes」.

Zone 1 — ruling, ⛔ non-negotiable

1. ⭐⭐ Both halves are IN SCOPE, and half 2's driver-memory work is legally unfrozen. Triage named the [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499 escalation on this card (5628469889, 2026-09-11T02:1xZ) — that is the one channel [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499's exception clause admits (「由分诊轮点名升级」). ⛔ You do not need to qualify it yourself, and ⛔ you must not try.
2. ⚠️ The escalation's basis is narrow — keep inside it. It is ⛔ not 「driver-memory has a bug」 (that would not qualify). It is: driver-memory is a registered face of the kit (verified by the seat — it imports the kit in three test files), so half 1 landing with driver-memory exempted would make the kit 「report conformance for a face it has stopped governing」 ⇒ a green that does not mean what it says ⇒ 「影响 CI 判绿的正确性」.
3. ⛔⛔ The escalation covers THIS window-construction seam only. ⛔ Not a general thaw of [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499. ⛔ Not licence to touch generateSql() — that is driver-memory analytics generateSql() reads neither granularity nor dateRange, so /analytics/sql echoes a statement the pipeline never ran — and accepts an hour that query() now refuses #17301, still pm:on-hold under the same freeze. If you find other driver-memory defects, report them, do not fix them.
4. ⚠️ A note so you do not stall when you read [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499: that anchor was edited today at ~13:0xZ (director ruling 5634032076) to carry a single machine-readable wake criterion, and the five holds under it were rewritten to quote it. ⛔ None of that touches the exception channel and ⛔ none of it reopens this card's escalation. Triage's naming stands.
5. ⛔ Do NOT touch packages/spec. Whether the schema should refuse these shapes is AnalyticsDateRangeSchema's array arm admits shapes every consumer now refuses, and the one shared refusal sentence is false for them #17598, in the maintainer's decision box. ⚠️ If AnalyticsDateRangeSchema's array arm admits shapes every consumer now refuses, and the one shared refusal sentence is false for them #17598 is later answered 「tighten the schema」, this card's population shrinks but its instrument gap does not close — the kit still needs the case.
6. ⛔ Do not weaken any existing kit case to make the new one pass.
7. ⭐ The rule the ARITY case must assert already exists — ⛔ do not invent a second one. PR fix(analytics): a dateRange array that is not a two-bound window is refused once, instead of meaning three different things #17593 made all four service-analytics faces refuse a non-two-bound array with the ADR-0112 ANALYTICS_DATE_RANGE_UNRECOGNIZED / 400 envelope. Assert that.
8. Clause-②: decide from measurement and put the line in the PR BODY at column 0 either way. A new case in an exported conformance kit changes what the kit demands of every registered face — argue it explicitly. ⛔ Never leave the line off; Check Changeset reads it there and ⛔ never reads this comment.

Zone 2 — the seat's assumptions, ⭐ labelled. ⛔ Your first job is to try to falsify them

#	claim	status	instrument
A	the kit has exactly one array-arm case, ANALYTICS_DATE_RANGE_EXPLICIT_WINDOW (analytics-date-range-conformance.ts:104); the other export, ANALYTICS_DATE_RANGE_REFUSED_SPELLINGS:87, is the string-arm vocabulary	MEASURED on 49cd71548	grep '^export const ANALYTICS_DATE_RANGE'
B	driver-memory is a registered face — it imports the kit in memory-analytics-date-range-conformance.test.ts, …-timezone.test.ts, …-utc-window.test.ts	MEASURED	git grep -l for the kit module + symbol
C	the guard is if (range.length === 2) at memory-analytics.ts:878, with the array arm taking bounds straight from timeDim.dateRange ⇒ a 1-element array leaves length 1 and skips the block	MEASURED as SOURCE — ⛔ the seat did not run it	⇒ this is still a reading; the probe is yours
D	service-analytics already pins the arity rule in its own package: __tests__/date-range-array-arm-arity.test.ts exists	MEASURED	⭐ read it first — it is the shape the kit case should generalise
E	memory-analytics.ts:1724 already documents throwing the ADR-0112 ANALYTICS_DATE_RANGE_UNRECOGNIZED envelope	MEASURED	⭐ the driver already knows the envelope; you may not need to introduce it

⚠️ Locate everything by symbol. Line numbers above are already a reading by the time you run.

Zone 1 (cont.) — ⭐ the probe comes FIRST, and a clean stop is a full success

⚠️⚠️ Half 2 is a SOURCE READING, ⛔ not a reproduction — the card says so in its own words, and the seat confirms it only read the source. ⇒ your first act is the probe against memory-analytics.ts:873-878.

⭐⭐ If the probe shows the window SURVIVES, that is a full success and a legitimate terminal outcome for half 2 — report it, do not manufacture a defect. Half 1 (the kit's arity case) would then still be owed, and its value is unchanged: ⭐ the corroboration for the reading is strong (the byte-identical if (range.length === 2) guard on NativeSQLStrategy was driven end-to-end on #17124 and emitted no WHERE clause at all for ['2026-01-01']), so a surviving window would itself be the interesting finding.

Zone 3 — suggested route, ⭐ optional, ⛔ not a fence

Probe → read date-range-array-arm-arity.test.ts → add the kit case → run it against both registered faces and let driver-memory go red → fix the driver face → green. ⭐ Order matters: making the kit case red first is what proves the case has teeth; adding the case and the fix in one motion leaves nobody able to tell whether the case would ever have caught anything.

⛔ Non-negotiable mechanics

• One task, one worktree. ⛔ Never edit the shared checkout, ⛔ never git stash.
• ⚠️ /tmp/claude-0 is SHARED across parallel devs and same-named files collide silently. Use a per-issue scratchpad path for all gate output.
• Gates: scripts/pm/dispatch-gates.mjs --commands then --ran. ⭐ Exit 3 = PREREQUISITE NOT MET — nothing was measured. ⛔ Never a pass.
• ⭐ $? after a pipe is the pipe's LAST stage. The seat re-committed this error again today. Redirect to a file.
• ⭐ A control that FAILS to fire voids the reading, and every count must name its population.
• ⚠️ Two packages here (packages/core + packages/drivers/driver-memory) — that is one lane and needs no cross-domain exception path (triage measured it). But ⛔ do not let it grow to a third.
• ⚠️ You cannot delete a remote branch in this environment (both git push --delete and the REST ref delete return 403 through the proxy). ⇒ ⛔ do not push a probe branch you do not intend to keep.
• Draft PR, Fixes #17596, changeset. ⛔ Do not touch content/docs/releases/.

Half 1 adds ANALYTICS_DATE_RANGE_NOT_A_WINDOW plus an arity case to the shared kit, asserting the rule PR #17593 already landed (ANALYTICS_DATE_RANGE_UNRECOGNIZED / 400) rather than a second one; no existing case was weakened and the two-element window case is the new case's control. Order followed Zone 3: the case alone produced 8 findings on driver-memory and 30 passes on service-analytics BEFORE the driver fix existed, so the case is provably not vacuous. driver-memory now refuses at the discriminator, the if (range.length === 2) guard that dropped the window is gone, and ResolvedDateRange.bounds is a tuple so it cannot return as a silent drop.

UPDATED — supersedes the report in comment 5635966823. Changed: the changeset grade (@objectstack/core patch to minor, per the ruling), the CI reading on the new head, and the open question, which the PM resolved.

  "premise_still_valid": true,
  "summary": "Unchanged from the first report except the changeset grade. Both halves landed: the kit gains ANALYTICS_DATE_RANGE_NOT_A_WINDOW plus an arity case asserting the rule PR #17593 already carries, and driver-memory's cube face refuses instead of dropping the window (the probe reproduced the drop end to end: one-element, empty and three-element arrays each produced a pipeline byte-identical to one with no dateRange, selecting every row). Follow-up round: @objectstack/core regraded patch to minor per the PM ruling, verified independently before editing — ANALYTICS_DATE_RANGE_NOT_A_WINDOW has 0 hits on origin/main against a control sibling with 4, and it is re-exported by packages/core/src/index.ts:92. @objectstack/driver-memory stays patch and the changeset now states why, in the sentence the ruling asked for: its public surface is byte-unchanged (the new helper is module-local, src/index.ts is not in the diff) and the behaviour it stops producing was a defect the contract never admitted. Nothing else in the diff moved.",
  "tests": "Check Changeset GREEN on the new head 4ab57672f6, re-read from the API, not assumed — and reproduced locally BEFORE pushing by driving the gate the way CI drives it (node scripts/check-changeset-no-major.mjs --base origin/main --event EVENT, with the real PR body in the synthesised payload): exit 1 on the old grade, exit 0 on the new one, verdict line 'LEVEL AXIS: ... grades a package whose packages/**/src/** it moves at minor or above'. FULL CI on 4ab57672f6, LATEST RUN PER CHECK NAME (raw listing is 45 runs across 33 names — counting raw over-reports, as warned): 33 names, 28 success, 5 skipped, 0 failure, 0 pending. All six required contexts green: Lint & Repo Gates, TypeScript Type Check, Test Core, Dogfood Regression Gate, Build Core, Temporal Conformance (live PG + MySQL). The 5 skipped are Build Docs, Console Pin Gate, Packed-tarball smoke (opt-in), plus Auto Label and Check PR Size, which flipped success to skipped only because they stand down on an 'edited' event — see the PR-body note below. Check Changeset itself has three runs on this sha (14:38:43Z, 14:59:45Z, 15:00:20Z), all success; the latter two are the body edit re-triggering it.",
  "mcp_calls": "1 — unchanged; this round used git and repo-scoped REST only.",
  "open_questions": [],
  "out_of_scope_findings": [
    "noted, not filed: PR-body write asymmetry, measured on this PR and matching the AGENTS.md warning that the cells disagree. REST create stored my session-URL footer byte-identical and appended nothing; REST PATCH (edit) APPENDED the platform's bare footer block on top of the body's existing one, leaving two. Fixed by re-sending the body with every footer stripped and letting the platform append exactly one — read back and confirmed at one. Carrier: anyone editing a PR body through REST in this repo; the reading belongs beside the existing per-surface table in pm-dispatch references/platform-readings.md rather than in a card of its own.",
    "noted, not filed: the PR body's Changeset section said 'patch for both packages' and would have misdescribed its own diff after the regrade. Corrected in place — a body edit re-runs only Check Changeset, not the pipeline, so it cost no full CI cycle.",
    "noted, not filed (carried from the first report, unchanged): service-analytics and driver-memory now spell one arity-and-bounds rule twice, held equal by the kit rather than by shared code; the platform-wide face census holds at five, measured; driver-memory's conformance runner throw was reworded to name the consequence."
