finding: no `objectstack.config.ts` in this repo reaches `MetadataPlugin._loadFromFileSystem` — the registry `filePatterns` glob has no measured consumer, which qualifies the invisibility rationale #11071 rests on

[os-zhuang]

Recording only — OBSERVATION class. ⛔ Not claimed, no assignee, no domain:*, no type. Found while implementing #11598 (converging the os init scaffold on the registry's NAME.TYPE.ts spelling). Dedup run at filing: two searches, no duplicate.

Nothing here is reported as broken. This records that a rationale several landed cards lean on is narrower than it reads, and that the load path it names has no measured consumer in this tree.

The rationale in question

packages/cli/src/utils/metadata-file-name.ts's docblock — the derivation #11071 built on, and quoted again in packages/cli/test/generate-file-name-registry-parity.test.ts:

MetadataPlugin._loadFromFileSystem primes every registered type by globbing that type's filePatterns, and that is the default (eager) bootstrap whenever no compiled artifact is configured. A scaffold whose name matches none of those patterns still type-checks, still passes os validate and still publishes, with nothing anywhere reporting that it was skipped — the silent-strip shape ADR-0063's retirement of os g agent closed (#10359).

Every clause of that is true for a project that boots eager with no artifact source. What it does not say is how many projects this repo scaffolds, ships or dogfoods actually boot that way.

What was measured

1. Three real scaffolds, compiled with the real os compile (tsx packages/cli/bin/run-dev.js compile), reading dist/objectstack.json back:

scaffold	compile exit	objects in the artifact
old spelling src/objects/my_app_item.ts (matches zero object patterns)	0	["my_app_item"]
same, plus src/objects/probe.object.ts (matches the pattern) not re-exported from the barrel	0	["my_app_item"]
new spelling src/objects/my_app_item.object.ts	0	["my_app_item"]

Row 1: the pattern-matching-nothing file is loaded. Row 2 is the discriminator — a file spelled exactly the way the registry declares, in the same directory, is not loaded when the barrel does not name it. So for these projects the glob is not consulted at all; the barrel's module specifier is the whole load path.

2. Why, mechanically. packages/runtime/src/standalone-stack.ts hands MetadataPlugin an artifactSource: { mode: 'local-file', path: artifactPath }, which routes _bootstrap to _loadFromLocalFile and never to _loadFromFileSystem. Its own comment says so: "Source-file scanner OFF — declarative metadata is loaded from the compiled artifact, not from yaml/json files on disk." os dev and os serve both boot that way, and os init's generated package.json wires every script through them.

3. The population. Every objectstack.config.ts tracked in this repo declares its objects in code rather than leaving them to the glob:

$ for f in $(git ls-files '*objectstack.config.ts'); do
 grep -q "import \* as objects\|from './src/objects" "$f" || echo "$f"
 done
packages/drivers/driver-memory/objectstack.config.ts
packages/plugins/plugin-auth/objectstack.config.ts
packages/plugins/plugin-hono-server/objectstack.config.ts
packages/plugins/plugin-security/objectstack.config.ts
packages/services/service-i18n/objectstack.config.ts

— and each of those five declares objects: from a named import too (plugin-auth: objects: authIdentityObjects), or declares no objects at all. The barrel-importing majority (examples/app-crm, create-objectstack's blank starter, everything os init writes) is the same shape. Zero configs in this tree rely on filePatterns to find their metadata.

Why it is worth recording

Two things follow, neither of them a defect on its own:

• The invisibility argument does not transfer to scaffolded apps. os init scaffolds NAME_item.ts while the registry declares *.object.ts — after #11071 the same project gets both spellings #11598 was filed on the reading that os init might be generating a file the project never loads. It is not — row 1 above. The card's own "what is NOT established" section had flagged exactly this, and it was right. A future card that reasons "filename matches no pattern ⇒ silently skipped" from the docblock alone will over-claim the same way, because the docblock states the mechanism without stating its precondition.
• filePatterns is a declared surface with no dogfood. The registry declares **/*.object.ts (and 26 other types' patterns) as the discovery contract, and this repo exercises it nowhere end-to-end: no example, no scaffold, no starter boots through _loadFromFileSystem. Whether that path still works on a real project is not something anything in this tree measures. The convergence os g writes NAME.ts for six generators while the type registry declares NAME.TYPE.ts — #11025 closed it for skill alone #11071 and os init scaffolds NAME_item.ts while the registry declares *.object.ts — after #11071 the same project gets both spellings #11598 landed is still right on its own terms — one CLI teaching one spelling, and the examples and registry already agreeing on it — but it is a consistency property, not the discoverability property the docblock frames it as.

What a picker-up might do (⛔ not a prescription — routing is triage's)

Options, roughly ascending in cost: amend the metadata-file-name.ts docblock to state the precondition (eager bootstrap, no artifact source) so the rationale stops reading as universal; or decide whether the eager glob path should have a dogfood at all, which is a scope question and probably the startup-focus answer is "no", in which case saying so beside the registry is the cheaper close.

Provenance

Measured on origin/main at c804f0ca5 while implementing #11598 (PR #12073) · the rationale quoted is from #11071 · #10359 is the silent-strip ruling both descend from.

Triage: finding → pm:queue + domain:cli, Task, S — the actionable close lands in packages/cli/src/utils/metadata-file-name.ts: amend the docblock (and its quotation in generate-file-name-registry-parity.test.ts) to state the precondition the measurement established — the glob-discovery mechanism applies only to an eager bootstrap with no artifact source, which no config in this tree uses — so the rationale stops reading as universal. On the second question the card raises, the startup-focus default applies and is recorded here as the disposition: no new end-to-end dogfood for the eager _loadFromFileSystem path is being minted for a surface with zero measured consumers; state that beside the registry's filePatterns declaration in the same PR (one sentence, pointing at this card). ⛔ Bounce clause: if while wording the precondition the dev measures the eager path actually broken (not merely unexercised), stop — that is a new Bug card against the loader, not a rider on a docblock edit.

Claim: PM loop round R37
Session: session_01HbG3rGVLjZStHQxHDtzJdJ
Branch: claude/issue-12075-filepatterns-precondition
Worktree: objectstack-issue-12075
Domain: domain:cli
File surface: packages/cli/src/utils/metadata-file-name.ts (docblock) + packages/cli/test/generate-file-name-registry-parity.test.ts (its quotation) — plus one sentence beside the filePatterns declaration, subject to the ownership fence below (stop on breach; explain in the report)
Container & model: S, mode:subagent, model: opus — above triage's S because the card carries a bounce clause and a cross-lane ownership question, both of which are judgement.
Clause-②: no — a precondition stated in prose. No schema, no accept/reject behaviour, no public surface moves.
Serial constraints cleared: no in-flight card touches either file. Siblings this round are different files in the same package ⇒ ruling ① exempts the package.

⚠️ Ownership fence — resolve this BEFORE writing the third edit

Triage's scope says to "state that beside the registry's filePatterns declaration in the same PR". I measured where that declaration actually lives on origin/main, because the answer decides whether the sentence is even ours to write:

packages/cli/src/utils/metadata-file-name.ts ← domain:cli (ours)
packages/cli/src/commands/generate.ts ← domain:cli (ours)
packages/metadata/src/metadata-manager.ts ← domain:engine (NOT ours)
packages/metadata-protocol/src/protocol.ts ← domain:engine (NOT ours)

⛔ If the sentence would land in packages/metadata* or packages/metadata-protocol, do NOT write it. Those are domain:engine's single-owner surface. Put the precondition on the cli-side declaration instead, and if you judge the engine-side declaration also needs it, file that unlabelled with a back-link and name it in your report. ⛔ Do not edit another lane's file on a docblock card, and ⛔ do not silently drop triage's instruction either — do one or the other and say which.

packages/spec is not involved: filePatterns is not declared there. I checked, so you do not have to.

⛔ The bounce clause — triage's, kept verbatim in force

if while wording the precondition the dev measures the eager path actually broken (not merely unexercised), stop — that is a new Bug card against the loader, not a rider on a docblock edit.

Unexercised ≠ broken. ⛔ Do not "fix" the loader on this card.

What the precondition must say

The docblock states a mechanism without its precondition, which is why it reads as universal. The measured facts to encode:

• The glob-discovery story holds only for an eager bootstrap with no artifact source.
• packages/runtime/src/standalone-stack.ts hands MetadataPlugin an artifactSource: { mode: 'local-file' }, routing _bootstrap to _loadFromLocalFile and never to _loadFromFileSystem. os dev and os serve both boot that way, and os init's generated package.json wires every script through them.
• Zero objectstack.config.ts in this tree relies on filePatterns; the barrel's module specifier is the whole load path.
• Triage's recorded disposition on the second question the card raises: no new end-to-end dogfood is being minted for the eager path (startup-focus default). State that, pointing at this card, rather than leaving it open.

⭐ The card's own discriminator is the part worth preserving in the wording: a file spelled exactly as the registry declares, in the same directory, is not loaded when the barrel does not name it. That single measurement is what turns "the glob might not be consulted" into "the glob is not consulted here".

⛔ Re-derive, do not inherit

The card was measured at c804f0ca5; origin/main has moved several times since. Re-run its measurements yourself before wording anything — and note this seat published a stale base sha to another dev on this same round, so ⛔ trust no figure in this comment either. Report what you measure.

Verification: prose-only, so there is no red-before state — ⛔ do not manufacture one. Report the anchored greps showing old wording gone / new wording present, and the parity test still green. Likely skip-changeset (no behaviour); justify whichever way you go.

Gate family: re-derive with node scripts/pm/dispatch-gates.mjs against your actual change set. Plus pnpm lint full-repo, not narrowed.

⚠️ Shared verify lock is heavily contended. ⛔ queue-timeout (exit 99) = nothing ran, never a pass — declare it. ⚠️ The task harness reports those tickets as "exit code 0"; the lock's own VERDICT line is the authority.

Standing fences: ⛔ packages/spec read-only · ⛔ never edit content/docs/releases/ · ⛔ never git stash · ⛔ no ratchet/debt-ledger edits to absorb an error. Out-of-scope findings: unlabelled, dedupe first, named in the report.
