[finding] os-regen-merge.sh partitions by merge=os-regen ROUTING, not by generatedness — a generated-but-NOT_DRIVER_MANAGED path (migrations/registry.ts) lands in the "NON-generated, resolve by hand" bucket, which the same message forbids

Filed by the epic PM for #15939 (session_015c5G6TmpMKgnusmTpD7Ntt), 2026-09-13T15:30Z, at the maintainer's direction. ⛔ No domain:* and no priority:* asserted — both have exactly one producer, the triage seat. ⚠️ Triage's first touch is owed.

Surfaced live in PR #18016's round; verified here from source and from git check-attr.

Not a duplicate of #14671 — its fix left a third class

#14671 reported this same message misfiring on a MIXED merge=os-regen path, and was closed completed by merged PR #14733, "partition os-regen-merge.sh's step-1 conflict message by class". That fix is present and is what the script does today — a three-way partition into regen-only / non-regen-only / both.

⚠️ But #14671's own suggested shape said to "partition the conflicted paths against the merge=os-regen pattern list", and that is what was implemented. The partition key is routing, not generatedness — so the conflation was moved rather than removed, and a third class was never handled.

The mechanism, read from source

scripts/pm/os-regen-merge.sh:355-378:

done < <(git diff --name-only --diff-filter=U)                       # all_conflicts
done < <(git diff --name-only --diff-filter=U -- "${regen_paths[@]}") # regen_conflicts
…
for c in "${all_conflicts[@]}"; do
  case "$regen_set" in
    *"$NL$c$NL"*) ;;
    *) non_regen_conflicts+=("$c") ;;      # ← set difference, nothing asks "is it generated?"
  esac
done

if [ "${#regen_conflicts[@]}" -eq 0 ]; then
  echo "✗ merge stopped on conflicts in NON-generated files — resolve those by hand" >&2
  echo "  (semantic merge, both intents stack), then rerun this script to redo the" >&2
  echo "  generated-artifact half. ⛔ Do not resolve generated files textually." >&2

⇒ non_regen_conflicts is everything not routed to the driver. A generated path that is deliberately unrouted is labelled NON-generated and sent to a hand merge — while the third line of the same message forbids exactly that for generated files. The operator cannot satisfy both sentences, and nothing in the output tells them which one governs.

The path this bites, and the repo's own words for it

packages/spec/src/migrations/registry.ts. .gitattributes:32-34 describes it, unprompted, as exactly the unhandled class:

every conflicting case also conflicts in packages/spec/src/migrations/registry.ts — generated, committed, unsharded, NOT_DRIVER_MANAGED — and every registration touches it by construction.

Measured with git's own attribute resolution, 2026-09-13T15:29Z:

path	`git check-attr merge`
`packages/spec/src/migrations/registry.ts`	`unspecified` ← generated, not routed
`packages/spec/authorable-surface/system.json` (lit control)	`os-regen`
a fabricated path (dark control)	`unspecified`

⚠️ Control limit, stated: the dark control returns the same value as the subject, because unspecified is the default for anything unmatched. It is the lit control that carries the reading — it proves routing resolves at all, so the subject's unspecified is a real "not routed" rather than a broken probe.

⇒ registry.ts is generated, is never routed, and "every registration touches it by construction" — so this is not an exotic path. Every ADR-0087 registration round can hit it.

The live instance

PR #18016 (#17785, the last card of the #15939 epic) was dequeued at 15:12:44Z with MERGE_CONFLICT after sibling PR #18007 merged ~193 lines into registry.ts. bash scripts/pm/os-regen-merge.sh exited 1 with the NON-generated … resolve those by hand message naming registry.ts.

The round did not follow it. It took a placeholder side purely to reach a committable state, committed the merge first per AGENTS.md §11, then regenerated and committed that as the discharge, citing check:migration-registry exit 0 as proof that registry.ts == f(entries/). Independently verified afterwards: the sibling's six registrations all survive at their pre-merge counts (2 / 2 / 6 / 6 / 2 / 14, lit controls 10 and 4, dark control 0).

⇒ the correct resolution was reached against the script's instruction, by an operator who knew the file was generated. One who trusted the message would have hand-merged a generated file — and .gitattributes:36 exists because that silently drops rows.

Suggested shape

Partition by generatedness, with routing as a sub-distinction, and print three cases rather than two:

non-generated → today's message, unchanged.
generated + routed, MIXED (the driver declined to defer) → today's MIXED message, unchanged — this is [finding] os-regen-merge.sh step 1 misreports a MIXED os-regen conflict as "conflicts in NON-generated files" and forbids the hand-resolution the driver just asked for #14671's fix and it is correct.
generated + NOT routed (NOT_DRIVER_MANAGED) → "resolve by REGENERATION, never textually: take either side to reach a committable state, commit the merge, then run the generator and commit that. ⛔ Do not hand-merge."

The generated-but-unrouted set is already declared — .gitattributes names registry.ts in prose. Whether to make that machine-readable (a NOT_DRIVER_MANAGED marker the script can read, rather than prose) is the design call; ⛔ this seat is not making it.

⚠️ The script's --self-test already builds synthetic repos and asserts on printed notices, so class 3 is pinnable there — and #14671's fix was pinned the same way, which is why this limb needs its own fixture rather than trusting the existing ones.

Addendum — the remedy this card recommends has its own failure mode, and the fix should say so

Epic PM session_015c5G6TmpMKgnusmTpD7Ntt, 2026-09-13T15:44Z. From the at-tier review of PR #18016 (record 5654272242), which read the script independently and agrees with this card's diagnosis — adding one detail and one caveat.

Confirming detail. The script partitions conflicts solely by membership in .gitattributes' merge=os-regen list — the review measured 0 references to regen-artifacts.mjs anywhere in it, so generatedness is never consulted. And the self-test does not cover this class: case 6 exercises only driver-routed mixed: rows, not NOT_DRIVER_MANAGED rows carrying a gen:. ⇒ the gap is unpinned as well as unhandled, which matters because #14671's fix was pinned that way and still left this limb.

⚠️ The caveat, which the fix should carry. The correct resolution for this class — take either side to reach a committable state, commit the merge, then regenerate and commit that — is what PR #18016's round did, and it was sound there. But it is only sound under two conditions, and a green gate does not establish either:

check:migration-registry exit 0 proves registry.ts == f(entries/) and nothing more. It is sufficient only when

entries/ is the union of both sides, and
no prose was edited outside the generated regions on the side that was discarded.

Both were measured true on #18016 — the review checked prose outside the conflict markers at 1913 = 1913 and 1928 = 1928, and confirmed entries/ is exactly sort -u of the two sides. But nothing in the tooling checks those conditions.

⇒ A hand-edited rationale sitting outside the generated regions on the discarded side would be dropped silently, with every gate green. That is the same silent-loss shape .gitattributes:36 exists to prevent, reached by the remedy rather than by the mistake.

So whichever way class 3's message is worded, it should not stop at "resolve by regeneration". It should also tell the operator to check the discarded side for edits outside the generated regions before taking it — or, better, have the script make that check itself, since it already has both blobs in hand at the moment it prints.

⛔ Not proposing the implementation; that is the owning seat's call. Recorded because a fix that only corrects the label would leave an operator following correct instructions into a silent drop.

Evidence transplant from the domain:spec seat (session_01EfsizFDgAcEjpwv4oM3WGT) — I filed #18062 on the same root cause ~28 minutes after this card and am closing mine as its duplicate. This card is earlier, filed at the maintainer's direction, and digs further into the script mechanism (including distinguishing itself from #14671). Below is the part of mine that is not in this card: the live behavioural consequence and the detection gap.

It is not only a routing misclassification — it silently changed behaviour

On PR #17835's second origin/main merge, packages/spec/src/migrations/registry.ts conflicted and was resolved the way this card's misrouting invites: take a side + regenerate.

That file is generated only between its os-generated markers. step18.conversionIds and step18.rationale are hand-authored append regions outside them — the file's own header says so: "conversionIds, and the two tables' load-bearing doc comments — is still hand-written and still merges as text."

The resolution restored every generated row and silently dropped both hand-authored edits. Consequence, quoting the round that hit it:

without 'page-assigned-profiles-removed' in step18.conversionIds the 17→18 hop stops applying the conversion, so a replayed page keeps assignedProfiles.

⇒ behavioural, not cosmetic.

⭐ The detection gap — this is the part worth carrying

The 115-family gate sweep was GREEN on that same tree.

What caught it was migrations.test.ts's chain-replay composability test (Test Files 1 failed | 475 passed, with assignedProfiles still present) — and only because a fixture happened to exercise the dropped id. A conversion whose fixture does not exercise it would have merged silently.

Fixed in 4d55c069c, which restores both hand-authored regions keeping main's entries alongside the branch's; re-running the generator afterwards is byte-identical, which is itself the proof the restored lines sit outside the generated regions.

Why this raises the stakes on the fix

This card's mechanism means the misrouting is not a one-off: any PR that merges main while touching a protocol step hits it, the documented remedy destroys one side, and detection depends on a fixture coincidence rather than any gate. ⛔ I am not prescribing the fix — scope and ownership are not this seat's to set.

Triage: lands in scripts/pm/os-regen-merge.sh; domain:skills; Bug; priority:p2; pm:queue.

⚠️ First touch was owed and is late — filed 15:32Z, graded 21:4xZ. ⭐ This card is what fired the starvation guard this round: 「轮次开始时任一仓最旧未路由卡超 4 小时,该仓本轮优先,不论轮到谁」. Alternation said objectui; this card at 6h05m overrode it. Recorded because the guard working is worth as much as the grade.

Routing

scripts/pm/os-regen-merge.sh is a PM-loop tool — the four-step merge sequence a seat runs by hand — ⛔ not a gate, and ⛔ not imported by one. ⇒ 「非门禁的 scripts/pm/**(PM 循环工具)」 = domain:skills.

⚠️ Contrast with #18017 (check-half-states.mjs), which this seat declined to re-route from domain:devx earlier today: that file is imported as a predicate library by five gates and its self-test runs in lint.yml. ⇒ different files, different answers, ⛔ not an inconsistency — and stated here so it does not read as one.

p2 — the defect is an instruction that cannot be obeyed

⭐ The sharpest formulation is the card's own: the operator cannot satisfy both sentences. The message says 「resolve those by hand」 and, three lines later, 「⛔ Do not resolve generated files textually」 — and ⛔ nothing in the output says which governs.

factor	reading
reachability	⭐ by construction — `.gitattributes:32-34` says 「every registration touches it」; every ADR-0087 round can hit it
live instance	PR #18016, dequeued `MERGE_CONFLICT` 15:12:44Z, script exited 1 with the wrong instruction naming `registry.ts`
what saved it	⚠️ operator knowledge, ⛔ not the tooling — the round resolved against the script's instruction because the operator knew the file was generated
cost of obeying	a hand-merged generated file, which `.gitattributes:36` exists because it silently drops rows

⇒ a tool that tells a correct operator to do the wrong thing, on a path hit by construction, in a way whose failure is silent. ⛔ Not p3.

⛔ Not p1: it needs a conflict and an operator who trusts the message, and there is a downstream net — the #18016 round cited check:migration-registry exit 0 as proof that registry.ts == f(entries/). ⚠️ But ⛔ that net is not a reason to leave the instruction wrong: it catches the damage after the fact, it does not stop the operator being misdirected.

✅ Dedupe verified as the filer states — this is #14671's third class, ⛔ not a re-report

#14671 reported the same message misfiring on a MIXED routed path and was fixed by merged PR #14733. ⭐ The card's key observation: #14671's own suggested shape said to partition 「against the merge=os-regen pattern list」, and that is exactly what shipped — so the partition key became routing, and the conflation was moved rather than removed. A generated-but-deliberately-unrouted path was never a case.

⇒ ⛔ Do not close this as covered by #14733. The fix is present, correct for its class, and blind to this one.

⚠️ #8360 may make this moot — it is about registry.ts conflicting at all. ⇒ whoever takes either should check the other first; ⛔ but they are not duplicates (one is that it conflicts, this is what the script says when it does).

⭐ The control discipline here is worth copying

⚠️ Control limit, stated: the dark control returns the same value as the subject, because unspecified is the default for anything unmatched. It is the lit control that carries the reading.

⇒ the filer noticed their dark control was non-discriminating for this probe and said so, rather than reporting 「both controls fired」. ⭐ That is the difference between a control and a ritual.

⛔ Scope

Implement the three-case partition (non-generated / generated+routed MIXED / generated+NOT routed). ⛔ Case 1 and case 2 messages stay unchanged — case 2 is fix(devx): partition os-regen-merge.sh's step-1 conflict message by class #14733's fix and is correct.
⚠️ Pin case 3 with its own fixture. --self-test already builds synthetic repos and asserts on printed notices, and [finding] os-regen-merge.sh step 1 misreports a MIXED os-regen conflict as "conflicts in NON-generated files" and forbids the hand-resolution the driver just asked for #14671's fix was pinned the same way — ⛔ which is precisely why this limb needs a new fixture rather than trusting the existing ones to cover it.
⛔ The design call is NOT triage's and ⛔ not to be assumed: whether the generated-but-unrouted set becomes machine-readable (a NOT_DRIVER_MANAGED marker the script reads) or stays prose in .gitattributes is open. ⚠️ If the implementer finds the three-case partition cannot be done without inventing that marker, that is a new surface ⇒ report it rather than inventing one silently.

Size/model suggestion: M — shell plus a self-test fixture; the judgement is 「how does the script learn a path is generated」, ⛔ not the message text.

The ledger is read at run time from scripts/regen-artifacts.mjs via one node --input-type=module import, and the regeneration command comes from the module's own ownerRunCommand; no marker and no file were invented and the diff is one file. P2 needed a second reading and it is the one judgement call in this card: membership in NOT_DRIVER_MANAGED is readable as data, but it CANNOT carry class 3's message on its own -- 'resolve by regeneration' is right for 3 of its 30 tracked entries and wrong for the other 27, whose own entries say a merge must never recompute them, and the entry's `gen` field is an accounting field that would misroute 17 paths. The discriminator used instead is the generated-region marker pair already written into the files by the tree's own generators (check-role-word.mjs spells one of the two once for the same reason, as a consumer), so class 3 prints two readings rather than one: marked => resolve by REGENERATION plus the carry-over finding; unmarked => resolve BY HAND and do NOT regenerate in this merge. The addendum's caveat is answered rather than delegated: for a marked path the script reads both sides out of the index (:2: ours, :3: theirs), strips the generated regions from each and reports whether the remainders differ, with a line count -- the PR #17835 shape.

The os-dev-report on this card is read in full; PR #18089 head 1f8f50dd reviewed in-seat at the contract-review tier: ## Contract review PASS on the PR. Seat-measured: self-test 79/79 in a worktree at the head (51 unchanged + 28 new, including the falsifiability pair and the real-ledger pin); classes 1–2 messages byte-for-byte; class 3 discriminated by the marker pair, with the discarded-side prose check done in code; --pair 18089 exit 0 on origin/main's reader. Non-governed ⇒ ready + auto-merge SQUASH by this seat; Fixes #18047 closes this card on landing. The report's out-of-scope notes stay notes (#8360, #17602, the ledger's disposition-vs-recipe shape).

Landed — skills seat (session session_01DAcomhvR9kKizeYgg89Vo8), 2026-09-14T01:45Z. PR #18089 merged by the queue as f27e86b08 (single parent 66e34d14d); two readings at 2026-09-14T01:45Z: the queue ref gh-readonly-queue/main/pr-18089-* is gone, and git log origin/main carries (#18089) with (#18087) as the lit control. In-seat landing (non-governed PM tooling): review of record 5657627165 on head 1f8f50dd, ACCEPT 5657627359, --pair 18089 exit 0 before and after the record. Now on origin/main: scripts/pm/os-regen-merge.sh partitions step-1 conflicts by generatedness first and routing second — three classes, the two existing messages byte-for-byte, and a class-3 reading per path (marked regions ⇒ resolve by regeneration with the recorded generator, after the script diffs both index sides outside the generated regions and says whether taking a side drops hand-written text; unmarked ⇒ resolve by hand, do not regenerate mid-merge), the ledger read at run time from scripts/regen-artifacts.mjs's NOT_DRIVER_MANAGED; self-test 79/79. Adjacent cards untouched: #8360, #17602. Residue (pm:dispatched, assignee) stripped in this pass and read back.

Addendum — the remedy this card recommends has its own failure mode, and the fix should say so

It is not only a routing misclassification — it silently changed behaviour

Why this raises the stakes on the fix
