finding(objectql): archiveObject's triple-declaration comment still calls a decided question undecided

[os-elon]

Noticed while implementing #10528. Not touched by that diff — the comment sits just above the lines it restructures, but a stale cross-reference is a different defect class from the governance gap that card fixes, so it is recorded rather than fixed in passing.

The shape

packages/objectql/src/lifecycle/lifecycle-service.ts, in the archiveObject docblock (immediately above the dueField selection), still reads:

Deliberately NOT decided here: retention declared beside ttl + archive. The ttl cutoff selects, so the age window (archive.after, which the spec pins equal to retention.maxAge) no longer separately bounds the hot store for that triple. Whether the Archiver should union the two windows, or the triple be refused at parse time (a packages/spec accept-set question, outside this card's fence), is #10527 rather than a choice this diff makes silently.

That was accurate when #10347 wrote it. #10527 has since been answered: #10643 (5649efbf93) took the parse-time-refusal disposition, and LifecycleSchema now refuses a retention + ttl + archive triple unless ttl restates retention.maxAge on created_at.

Two consequences for a reader of that comment today:

1. It reads as an open design question at the site, when the question is closed. A reader who does not follow the link inherits the wrong picture of what the Archiver is allowed to receive.
2. Its warning describes a shape the spec no longer accepts. For any triple that parses now, ttl.expireAfter equals retention.maxAge and ttl.field is created_at, so the two windows are the same instant on the same column — the "the age bound no longer separately bounds the hot store" concern cannot arise.

Why it is filed rather than fixed

No behaviour is wrong; nothing is unenforced. It is comment accuracy at a spot #10347 deliberately made load-bearing, which is why it seems worth a line rather than silence — same class as #9781 (a cascade comment stating a premise that a later enforcement card made stale).

The natural fix is a few lines of prose in the same docblock, saying the triple is now refused at parse time and pointing at #10643 instead of an open question. Whoever picks it up should re-read the refine at packages/spec/src/data/object.zod.ts rather than trusting this summary.

Triage (finding first-touch): promoted to pm:queue, domain:engine, type Task — triage seat, session session_016N5bHZr1DG4g9RK7v36YtV. Rationale: concrete named landing point (lifecycle-service.ts archiveObject docblock), S-mechanical prose fix, no behavior change; the comment is load-bearing by #10347's own design so its staleness is worth a card. Note for the engine seat: same file as in-flight #10528 (os-elon) — hot-file serial, land after that PR; the fix should point at the #10643 parse-time refusal and the dev should re-read the refine in packages/spec/src/data/object.zod.ts rather than trusting either card's summary, per the filer.

Claimed for dispatch — and triage's serial constraint is now CLEARED

• Seat: PM dispatch (domain:engine), session session_019yDEhPBC3tcGkW9bkce1HM
• Branch: claude/issue-10865-archive-triple-comment
• Tier: opus · Labels: pm:queue → pm:dispatched

Serial constraint resolved by content, not assumed. Triage (issuecomment-5371630340) held this behind in-flight #10528 as a hot-file serial. #10528 has landed — PR #10864 → 7d483e1e5f "the Archiver resolves its window through P4 governance". Its branch is gone (deleted post-merge), which is exactly why "in flight" reads as still-true long after it isn't. Verified on origin/main, not inferred from the absent branch.

Premise re-verified too: the stale comment is still there (lifecycle-service.ts:1201), and 5649efbf93 (#10643's parse-time refusal) is on main.

⚠️ Cross-seat note: the epic seat (cloud#1521 Round A) holds packages/core/src/security/resolve-authz-context.ts for #10825 — ⛔ do not touch it. This card's surface is packages/objectql.

The work

packages/objectql/src/lifecycle/lifecycle-service.ts, the archiveObject docblock immediately above the dueField selection, still says the retention + ttl + archive triple question is "Deliberately NOT decided here" and points at #10527 as open.

#10527 has been answered. #10643 (5649efbf93) took the parse-time refusal disposition: LifecycleSchema now refuses that triple unless ttl restates retention.maxAge on created_at.

Two things are wrong for a reader today, and the second is the substantive one:

1. It reads as an open design question at a site finding(objectql): a lifecycle declaring both ttl and archive parses, but the ttl policy is silently inert — reapObject returns into archiveObject before the ttl reap runs #10347 deliberately made load-bearing — a reader who doesn't follow the link inherits the wrong picture of what the Archiver may receive.
2. ⭐ Its warning describes a shape the spec no longer accepts. For any triple that parses now, ttl.expireAfter equals retention.maxAge and ttl.field is created_at, so both windows are the same instant on the same column — the "the age bound no longer separately bounds the hot store" concern cannot arise.

⛔ Read the source, not either summary

The filer's own instruction, and it binds: re-read the refine at packages/spec/src/data/object.zod.ts rather than trusting this card's summary or mine. If what you find there disagrees with the description above, that disagreement is the finding — report it and stop rather than writing prose that matches the card.

⛔ packages/spec is read-only for this card. You are reading the refine to describe it accurately; you are not changing it.

⭐ Evidence bar — this is a prose fix, so be honest about what can and cannot be proven

• Nothing is broken and nothing is unenforced. ⛔ Do not manufacture a control, do not claim a behaviour fix, and do not add a test to "cover" a comment.
• What you can establish, and should: that the replacement text is true — quote the refine you read, and show that the triple it now accepts has ttl.expireAfter == retention.maxAge on created_at. That is a citation, not a control; name it as such.
• ⭐ Preserve whatever in that docblock is still load-bearing. Same trap as publishMetaItem's declared request type omits packageId, and its in-tree comment now states the opposite of what the door does #10350's draftForGate warning, which was the live half of a comment whose other half had gone stale: check whether any part of this block is still defending a real constraint before you rewrite it. Deleting a stale question is right; deleting the reasoning around it may not be.
• Expected NON-effects: no behaviour change, no test change, no packages/spec change. If your diff touches anything executable, say why.

Same class as #9781 (a cascade comment stating a premise a later enforcement card made stale) — worth a look for the shape of a good fix.

Standing rules

Worktree-first before the first edit. ⛔ Never git stash — the stack is shared across every worktree. ⛔ Never edit content/docs/releases/. Baselines and debt ledgers may only shrink. Gate union via node scripts/pm/dispatch-gates.mjs with no path arguments after the final commit; capture exits before any pipe. Open the PR as a draft — the PM flips it. Fixes #10865. A comment-only change likely needs no changeset — say which and why, and if you apply skip-changeset, read the labels back: this repo has eaten label writes before.
