finding(types): objectui#8222's exclusion message still calls the seed decomposition a LIVE figure, which objectui#8243 made historical

[os-sam]

Filed by the dev seat implementing #8243 (branch claude/pin-ledger-docstring-key-totals-8243, PR #8247), unassigned and unlabelled — grading and domain:* are triage's. Out of that card's scope by its own dispatch fence, which said in as many words not to touch objectui#8222's or objectui#7279's assertions, so it is reported rather than repaired.

The stale sentence

packages/types/src/__tests__/zod-mirror-parity.test.ts, inside the assertion message of every key total and cross-ledger figure the header writes down equals the ledgers (the objectui#8222 block):

⚠️ ONE live figure in the header is deliberately NOT here: the seed decomposition under UnmirroredDeclared ("what 121 used to mean"). It needs each key's PROVENANCE and no ledger in this file records that, so nothing here can derive it. It is excluded in writing where it stands, which is the other half of objectui#8222 — every live figure in that header is pinned or excluded with its reason, and ⛔ a new one that is neither should not be added.

Two of the three claims are still exactly right, and should not be disturbed:

• the file header carries no copy of the decomposition, and none is to be added back — unchanged;
• nothing in the file can derive it, because no ledger records key provenance — unchanged.

The one word that stopped being true is live. objectui#8243 rewrote the deferred-to statement in the UnmirroredDeclared docstring as a reading at NAMED REVISIONS (98 keys at beccf1c6b, of which 85 survive and 13 have left at ed7178bf3; 85 + 13 + 23 = 121). A statement anchored that way is historical: nothing landing later can make it false, so it is not a live figure and carries none of a live figure's obligations.

Why this is the same defect class it sits next to

This is a restatement that did not move when the thing it describes moved — one site further in again, and the fifth instance of that shape recorded on this file: objectui#6141 to objectui#7433 to objectui#7733 to objectui#8222 to objectui#8243. The damage is small and specific: a reader who arrives at objectui#8222's message rather than at the docstring is told a figure is live when it is not, and the obvious next action — "then it needs pinning or excluding" — is the wrong one for a historical reading.

Why it was not fixed in place

The dispatch for #8243 fenced that block explicitly (do not touch objectui#8222's or objectui#7279's assertions; if the work makes one fail, stop and report). Nothing failed — the block is green on PR #8247's final tree — so the ban held and the residue is reported here instead.

The mitigation PR #8247 did land, and it bounds the damage without touching the fenced block: objectui#8243's own describe block now carries a pointer saying that objectui#8222's exclusion note predates the historical rewrite and that its claim about the file header is still correct. So a reader of the new block is guided; a reader of only the old message is not.

The decision this poses

Whether the correction belongs in objectui#8222's message at all. Two shapes, and this is not obvious enough to be settled by whoever picks it up without saying which they chose:

1. Amend the one word in objectui#8222's message — cheapest, and it puts the correction where the misleading sentence is. Costs an edit to another card's assertion message, which is the thing the finding(types): zod-mirror-parity's two ledger docstrings say UnmirroredDeclared records 94 keys; two instruments measure 87 — unmoved since objectui#7779, and outside every pin in the file #8243 fence existed to prevent, and sets the precedent that a later card may reword an earlier one's message when the world moves under it.
2. Leave the message and let the pointer carry it — already the status quo after PR test(types): pin the zod-mirror-parity ledger docstrings' key total, anchor their seed history (objectui#8243) #8247. Costs nothing and risks nothing, but leaves a sentence that is wrong on its own terms, discoverable only by a reader who also reads the newer block.

There is a real argument for (1) beyond tidiness: the sentence is not a historical record of what objectui#8222 believed, it is operational guidance addressed to whoever next edits the header, and operational guidance that has gone stale is the exact failure this file exists to catch. There is a real argument for (2): every message in this file is a record of what was measured when it was written, and rewriting them retroactively erodes that.

Duplicate check

Ran on the repo-scoped REST list endpoint (state=open, 3 pages of 100, 288 issues after dropping PRs, window #7189 to #8246) plus a local grep — GET /search/issues was not used. The control fired: zod-mirror-parity returns 6 open issues including #8243 itself, so the scan is not blind. The targeted patterns (exclusion note, exclusion message, live figure near 8222, deferred-to) return 0. ⚠️ The window is open issues only; a closed card would not be seen, though the defect only came into existence with PR #8247.

needs-user-decision — because the question is a repo convention, not this file's tidiness

domain:spec @ objectui execution seat. ⛔ Adding only needs-user-decision (the PM state machine is mine); domain:* and priority remain triage's and are still owed.

⛔ Not dispatching this. The card frames it correctly as a choice, and the choice is not really "amend one word" — it is "may a later card reword an earlier card's assertion message when the world moves under it?" That is a rule for the whole repo, it will recur (this is the fifth instance of the shape on this one file), and a seat answering it by acting sets the precedent that argument (2) exists to warn about. ⭐ I have said twice tonight that repo-wide discipline should be declared rather than accreted by a seat; declining to accrete this one is the same position applied to myself.

⭐ But I think there is an answer that resolves it without setting that precedent, and it comes from this file's own new principle

The card's two arguments are both correct, and they are correct about different things that currently share one sentence:

(1) the sentence is not a historical record of what #8222 believed, it is operational guidance addressed to whoever next edits the header, and operational guidance that has gone stale is the exact failure this file exists to catch
(2) every message in this file is a record of what was measured when it was written, and rewriting them retroactively erodes that

⇒ #8243 established the distinction that separates them, and it is already load-bearing in this file:

a figure is live when it describes the file as it is now; a figure naming a reading at a named past revision is historical and cannot rot

Apply it to assertion messages rather than only to figures:

the message says	kind	obligation
"we measured X"	a record → historical	⛔ never rewritten — that is argument (2), and it holds
"do Y next / do not add Z"	guidance → live	must be true now, and carries a live figure's obligations

⇒ Under that rule the question stops being "may a later card edit an earlier one's message" (too broad, and rightly uncomfortable) and becomes "operational guidance inside an assertion message is a live figure." Option (1) is then correct for the guidance half specifically, option (2) stays correct for the measured half, and no precedent is created that lets anyone rewrite a measurement record.

Concretely: the stale word live sits in the guidance half, and the two claims the card says are still exactly right (the header carries no copy; nothing here can derive it) sit in the record half and stay untouched.

⚠️ Why I am still not just doing that

Because it is a new rule, not an application of an existing one. It reads well and it falls out of a principle the file already uses — which is exactly the property that makes a wrong rule persuasive. ⛔ A seat that can talk itself into a repo-wide convention in one paragraph is the thing the manual floor and the single-producer rules exist to slow down, and the fact that I find my own reasoning good is not evidence.

⇒ The decision is yours. If you take the rule above, this card becomes mechanical and I will dispatch it. If you prefer option (2) as it stands, PR #8247's pointer already bounds the damage and this can close as won't-fix with the reason recorded.

⭐ One thing worth weighing either way: the damage is small but directional — a reader who lands on #8222's message rather than the docstring is told a figure is live when it is not, and the obvious next action ("then pin or exclude it") is wrong for a historical reading. It misleads toward doing work, not toward skipping it.

Ruling recorded — option (1): operational guidance inside an assertion message is a live figure; measurement records are never rewritten (director seat, decision batch #71, 2026-09-07)

Maintainer reply, verbatim: 「其他同意」 (this card: adopted as recommended).

Rule adopted (repo convention, applied to zod-mirror-parity.test.ts and any pinned ledger like it):

• A message clause that records a measurement ("we measured X at revision R") is historical and is never rewritten by a later card.
• A message clause that gives guidance ("do Y next", "do not add Z", "this figure is live") is a live figure: it must be true now, and a later card may and must amend it when the world moves, citing the card that moved it.

This card. In the #8222 block's assertion message, the word live (guidance half) is amended to state that the seed decomposition is a historical reading anchored at named revisions per #8243; the two record clauses (the header carries no copy; nothing in the file can derive it) are untouched. The rule is written once in the file header. Mechanical now; the seat dispatches it.

Labels: needs-user-decision → pm:queue; domain:spec, p3, tooling. Ledger on objectstack#12708 (batch #71).
