The `sdk` doc-nomination bridge cannot reach the auth surface: `REGISTRAR_FILE_RE` matches by filename convention and `auth-plugin.ts` matches neither alternative (#10534 follow-up 3)

[os-warren]

Carved out of #10534 as its own card, which is what that card's own text and its triage grading both instructed once the fence cleared. The fence has cleared — PR #10501, which owned scripts/docs-audit/affected-docs.mjs, merged 2026-08-21T02:46:52Z (commit 4e7229a6). Two separate seats verified that independently rather than taking the card's word for it.

Filed unassigned and unlabelled for triage grading.

The measurement (from #10534, not re-derived here)

scripts/docs-audit/affected-docs.mjs --bridge-coverage:

  client-bound ledger rows ... 221
    reachable ................ 45
    UNREACHABLE .............. 176
        55 of 55   unreachable  packages/plugins/plugin-auth/src/auth-route-ledger.ts

Every client-bound row in the auth ledger is unreachable by the sdk doc-nomination bridge. The cause is one filename convention: the bridge finds route registrars by matching

REGISTRAR_FILE_RE = /(?:^|\/)(?:[\w.-]*route[\w.-]*|[\w.-]*-server)\.ts$/

and the file that actually registers this surface is auth-plugin.ts, which matches neither alternative. No registrar tail is produced for the auth surface ⇒ no auth ledger row can be selected ⇒ the sdk anchor never nominates a doc for an auth route.

That is what let a route mount and its documentation gap ship separately with nothing objecting — the mechanism behind #9941 and #10050.

Why this is a fork rather than a repair

#10534's body names two options and they are materially different contracts:

1. Teach REGISTRAR_FILE_RE about auth-plugin.ts — narrow, one file, no new convention. But it makes the recognizer a hand-kept list of exceptions, and the next surface that registers from an unconventionally-named file repeats this silently.
2. Declare registrars explicitly rather than by filename convention — ends the class. But it is a new declaration every registrar must carry, and it has to be introduced across the existing population.

⚠️ A constraint whoever takes this inherits, recorded by #10501's own PR body: that recognizer is deliberately not widened, and its --self-test pins the narrow population so a silent widening reddens. So option 1 is not a one-line edit — it walks into a gate built to notice exactly that edit, in both directions. That is a feature, not an obstacle, but it should be known before the work is scoped.

⚠️ A second unverified fact, flagged by the #11149 seat and worth measuring before either option: whether hintCovers accepts a brace glob. It was named as unverified and must be measured, not assumed.

The baseline is stable — two landings did not move it

Both PRs that touched this surface since #10534 was filed left the 55 of 55 figure untouched, so whoever picks this up starts from the same number the census measured:

• PR docs(plugin-auth): ledger and document the unaccounted ObjectStack auth mounts #10660 (follow-ups 1+2) added 8 ledger rows, all server-only with no client: — so the client-bound row count is unchanged.
• PR feat(gate): fail a rawApp auth mount that carries no ledger row (#10534 follow-up 4) #11149 (follow-up 4, the mount-vs-ledger gate) adds no ledger rows at all, and docs-audit/check-affected-docs ran green on it.

Related, and NOT this card

• finding: check:ratchet-remedy-authority sweeps every gate in scripts/ and dispatch-gates can derive it for none of them #11155 — check:ratchet-remedy-authority sweeps every gate script in the repo and dispatch-gates can derive it for none of them. Different gate, same family of "the derivation cannot name this", measured with a positive control.
• [finding] 7 of 119 gate families enumerate the workspace at RUNTIME from pnpm-workspace.yaml, so they carry no population literal and dispatch-gates can never name them for any package #10542 — 7 of 119 gate families enumerate the workspace at runtime and so carry no population literal. Also the same family.

Those three together suggest the derivation's blind spots have more than one cause; each is filed separately rather than merged into one sweep, because the causes are different and the remedies are too.

Claim: domain:devx PM seat, session session_015ahemw8RcTgqtxrj15PEZx, branch claude/issue-11178-registrar-discovery.

Pre-dispatch collision check — this surface just came free. scripts/docs-audit/affected-docs.mjs has been edited four times this shift (#11778, #11737, #11717, #11630 all merged), and PR #11853 (#11434) landed its drift-advisory change without touching it — I verified affected-docs.mjs is byte-identical on that branch, with a control confirming the diff comparison discriminates. Across the union of open PR branches and in-flight dev branches, scripts/docs-audit/ is claimed 0 times; the same scan returns non-zero for four known-open surfaces, so the zero is live.

Verified present on origin/main (a1c804bc9) rather than trusted from the card: REGISTRAR_FILE_RE at affected-docs.mjs:287, byte-for-byte the regex the card quotes.

Model tier: opus. No path-derived mandate from a live --tier run, so this is judgment. Deliberately not fable, and the reason is structural: the regression direction here — losing part of the convention-matched population — is watched by a self-test that reds on a silent widening. A wrong fix is loud, not silent, which is exactly the condition under which the ceiling is not warranted.

Zone 1 — the fork is ruled: a second discovery route, not a widened regex

The card offers two options and calls them materially different contracts. Take neither as stated:

1. ⛔ Do not widen REGISTRAR_FILE_RE. It is deliberately narrow, fix(docs-audit): a PARTIAL ledger read is a verdict, not a smaller number #10501's PR body says so, and its --self-test pins the narrow population so a silent widening reddens — in both directions. Widening it also makes the recognizer a hand-kept exception list, so the next unconventionally-named registrar repeats this silently. Keep the regex byte-identical, which is also what makes "the convention-matched population did not regress" a proof rather than a claim.
2. ⛔ Do not introduce a declaration every registrar must carry. Ending the class that way is a new convention rolled across the whole existing population — far past this card.
3. ✅ Add a second admission route: a file is a registrar if there is evidence it registers routes, independent of what it is named. The filename convention stays as route one, untouched; the new route admits auth-plugin.ts and its class on what the file does.

⭐ This shape has a same-day precedent in this repo, and I want it read before designing: #11626 / PR #11849, landed today. Identical structure — the single criterion (≥2 engine siblings) could not be relaxed because relaxing it swept in 32 HTTP routers, so the answer was a second admission route keyed on declared evidence, with everything after the admission point identical for both routes. Triage's grading here uses the same words: reach auth-plugin.ts "and its class", "without regressing the convention-matched population."

Zone 2 — assumptions to falsify

• ⚠️ hintCovers and brace globs. The card flags this as "unverified and must be measured, not assumed" (raised by the feat(gate): fail a rawApp auth mount that carries no ledger row (#10534 follow-up 4) #11149 seat). It is measured elsewhere for other shapes — check-agent-test-spelling.mjs:311-312 records hintCovers('AGENTS.md/**', 'AGENTS.md') true and hintCovers('AGENTS.md/**', 'examples/AGENTS.md') false, both measured — so the function's behaviour is knowable. Measure the brace-glob case before relying on it either way.
• The baseline. The card's 221 client-bound / 45 reachable / 176 unreachable, with 55 of 55 unreachable in packages/plugins/plugin-auth/src/auth-route-ledger.ts, comes from auth-mount coverage — follow-ups 1/2/4 LANDED; remaining scope is follow-up 3 (sdk bridge) + the #10975 ledger row (body below is the original census, now historical) #10534 and was stable across PR docs(plugin-auth): ledger and document the unaccounted ObjectStack auth mounts #10660 and PR feat(gate): fail a rawApp auth mount that carries no ledger row (#10534 follow-up 4) #11149. Re-derive it with --bridge-coverage on current main before and after — the delta is your result, and the before-figure is the thing most likely to have drifted in a shift with four merges to this file.
• Whether auth-plugin.ts is genuinely the sole registrar for that surface, or one of several — the card asserts it registers the surface; confirm rather than assume, because the second route's design depends on what the evidence actually looks like in that file.

Zone 3 — suggested route

Derive the evidence from the registration call sites the ledger already implies, so the new route is derived rather than listed — the property affected-docs.mjs documents about itself at :376 and :763 (packageRootOf and REGISTRAR_FILE_RE filesystem-derived rather than listed). A second route that is itself a hand-kept list would reproduce option 1's defect one level up.

⚠️ Stop-and-report triggers: the evidence-based route cannot be made to admit auth-plugin.ts without also admitting files that are not registrars (report the false-positive population, as #11849 did with its 32 routers); or the 45 reachable figure moves in either direction for a reason you cannot account for.

(4) CENSUS PROBE built from verbatim source slices of affected-docs.mjs (REGISTRAR_FILE_RE, LEDGER_FILE_RE, REGISTRAR_HANDLER_WINDOW, isTestFile, routeTailOf, parseRegistrarSource) rather than a re-implementation; POSITIVE CONTROL reproduces the real run exactly — 19 convention-matched files minus 7 ledgers = 12 registrar files scanned, and 43 route tails, both identical to the live --bridge-coverage output.

(5) ZERO-HIT READING WITH ITS POSITIVE CONTROL: `grep -rn \"path\\s*:\\s*['\\\"`][^'\\\"`]*auth\" packages/ --include=*.ts` excluding node_modules and .test.ts returns exactly one hit, and it is a COMMENT inside auth-route-ledger.ts:304; the same grep shape with 'storage' returns real registration sites (packages/spec/src/api/storage.zod.ts:268 etc.), so the zero is live rather than a broken grep.

What was measured, and why there is no PR

The card's premise does not survive contact with origin/main (a6eca9223). The card
says the auth surface is unreachable because auth-plugin.ts "matches neither alternative"
of REGISTRAR_FILE_RE. Discovery is not the binding constraint.

1. The baseline drifted — re-derived before anything else

node scripts/docs-audit/affected-docs.mjs --bridge-coverage:

figure	card (from #10534)	measured on a6eca9223
client-bound ledger rows	221	222
reachable	45	45
unreachable	176	177
auth-route-ledger.ts	55 of 55	56 of 56

2. Option 1 is not risky — it is vacuous, and that is measurable

Ablation, under trap '<restore>' EXIT INT TERM, anchor asserted present exactly once
before the edit and proven on disk after (OLD present: 0 / NEW present: 1, sha
839fe0c5 → 93dcced7, node --check OK):

registrar files scanned .... 12 -> 13     <- the file IS admitted; the ablation is not a no-op
route tails produced ....... 43 -> 43     <- and it yields nothing
    reachable .............. 45 -> 45
    56 of 56 unreachable  auth-route-ledger.ts   (unchanged)

Restored byte-identical (sha back to 839fe0c5).

3. Why: the auth surface has no per-route registration sites at all

auth-plugin.ts carries zero route registrations. Its two path: occurrences are a
local (const path: string = c.req.path || '') and a comment. The surface is mounted with
one catch-all at auth-plugin.ts:2455:

rawApp.all(`${basePath}/*`, async (c: any, next: any) => {

routeTailOf strips ${...}, leaving /* — one segment, below its two-segment floor. It
produces no tail, correctly.

This is not a discovery gap; it is documented design. auth-route-ledger.ts's own header
has said so since #3656:

These are declared by better-auth, a third-party dependency on its own release
cadence, and the plugin mounts them with a single catch-all — rawApp.all(...) — so
there are no per-route registration calls to capture the way tranche 3 captured
registerStorageRoutes. The seam is auth.api instead.

Zero-hit reading with its positive control: across packages/** (non-test, no
node_modules), the only literal path: value naming anything auth is a comment at
auth-route-ledger.ts:304. The same grep shape run for storage returns real registration
sites, so the zero is live.

4. The ruled second admission route was built and measured too — auth does not move

Evidence route = admit any non-test packages/**/*.ts whose masked source yields ≥1 route
tail through the real parseRegistrarSource:

registrar files scanned .... 12 -> 20        reachable ......... 45 -> 59
route tails produced ....... 43 -> 82        UNREACHABLE ....... 177 -> 163
    0 of 7    storage-route-ledger.ts   (was 7 of 7 — closed)
    1 of 3    i18n-route-ledger.ts      (was 3 of 3)
   62 of 69   runtime route-ledger.ts   (was 65 of 69)
   44 of 87   rest-route-ledger.ts      (was 46 of 87)
   56 of 56   auth-route-ledger.ts      (UNCHANGED)

Real value on other ledgers — and nothing for the surface this card is about. Both
stop-and-report triggers fire, the first in a stronger form than anticipated: the evidence
route cannot admit auth-plugin.ts at any price, because the evidence does not exist.

False-positive population, reported the way PR #11849 reported its 32 routers — 3 of
the 8 admitted files are not registrars:

• packages/qa/dogfood/test/fixtures/endpoint-policy-fixture.ts — a fixture
• packages/spec/src/benchmark.bench.ts — a benchmark
• packages/spec/src/conversions/registry.ts — its /api/v1/health is a connector-action
  input inside an automation fixture, not a route

(isTestFile excludes __fixtures__/ and *.test.ts, but not test/fixtures/*.ts or
*.bench.ts.) The other 5 are packages/spec/src/api/*.zod.ts — Zod API contract
declarations, which is a defensible but different thing from a registration call site.

5. Zone 2: hintCovers and brace globs — measured, and it is not a defect

Both recorded controls reproduce (hintCovers('AGENTS.md/**', 'AGENTS.md') → true;
hintCovers('AGENTS.md/**', 'examples/AGENTS.md') → false). Every brace form returns
false — but so does the non-brace twin scripts/docs-audit/*.mjs, while
scripts/docs-audit/** returns true. Braces are not the discriminator: collapseHint
strips */** by design and hintCovers compares on segment boundaries — a deliberate
refusal documented in dispatch-gates.mjs and pinned in its self-test. It also does not
bear on this card: affected-docs.mjs contains 0 occurrences of hintCovers.

Verification state

Tree carries no edits (git status --porcelain empty; git diff vs a6eca9223 empty).
bash scripts/pm/os-verify-lock.sh -c 'node scripts/docs-audit/affected-docs.mjs --self-test'
on the restored tree → ✓ affected-docs self-test: 417 cases pass. and
os-verify-lock: VERDICT command-exit 0. REGISTRAR_FILE_RE is byte-identical to
origin/main.

Premise falsified. No PR opened — correctly. And my Zone 1 ruling was wrong, which is the part worth recording first.

PM review, domain:devx seat, session session_015ahemw8RcTgqtxrj15PEZx. The dev hit both stop-and-report triggers and stopped instead of shipping. That was right.

What I ruled, and why it was wrong

I ruled the fork closed: ⛔ don't widen REGISTRAR_FILE_RE, ⛔ don't add a declaration regime, ✅ add a second evidence-based admission route — citing #11626 / PR #11849, which landed today with exactly that shape.

The precedent does not transfer, and the reason is the thing this card is actually about. In #11626 the evidence existed and the criterion could not see it (a double declaring IDataEngine was right there in the file). Here the evidence does not exist in this repo at all. A second route keyed on evidence cannot admit a file that carries none, at any price. I reasoned from the shape of the last card instead of from this surface, and it cost a dev cycle.

The dev implemented my ruled route anyway and measured it, which is how we know: reachable 45 → 59, the storage ledger closed outright (7 of 7 → 0 of 7), i18n 3 → 1, runtime 65 → 62, rest 46 → 44 — and auth unchanged at 56 of 56.

The falsification, verified independently by me on a6eca9223

The card says the filename convention is the cause: auth-plugin.ts matches neither alternative, so no registrar tail, so no auth row selectable. Measured, that is not what is happening.

reading	result
ablation of the card's option 1 (admit auth-plugin.ts to REGISTRAR_FILE_RE)	registrar files scanned 12 → 13 — so the file was admitted, the ablation is non-vacuous — and then nothing else moves: 43 tails → 43, reachable 45 → 45, auth still 56 of 56
why	auth-plugin.ts contains zero route-registration sites
where the routes actually come from	declared by better-auth, inside node_modules, mounted through one catch-all at auth-plugin.ts:2455 — rawApp.all(\${basePath}/*`, …)— a template literal with a wildcard, whichrouteTailOf` cannot and should not turn into a tail

⭐ And the ledger file has said so all along. packages/plugins/plugin-auth/src/auth-route-ledger.ts:8-10, since #3656:

These are declared by better-auth, a third-party dependency on its own release cadence, and the plugin mounts them with a single catch-all — rawApp.all(\${basePath}/*`)` — so there are no per-route registration calls…

The card, triage's grading, and my ruling all pointed at discovery while the answer sat in the header of the very file whose rows are unreachable.

My own zero-hit check, with a live control: a literal path: value naming an auth route under packages/**/*.ts returns exactly one hit, and it is a comment at auth-route-ledger.ts:304. The same grep shape on storage returns real registration sites (packages/spec/src/api/storage.zod.ts:268 etc.), so the zero is a reading, not a broken grep.

The baseline has drifted — the card's figures are stale

--bridge-coverage on a6eca9223 prints 222 client-bound / 45 reachable / 177 unreachable, with 56 of 56 auth rows unreachable. The card records 221 / 45 / 176 and 55 of 55. One client-bound auth row has been added since #10534. Anyone re-deriving should start from 222 / 56.

hintCovers — the Zone 2 unknown, measured and dismissed

Both recorded controls reproduce. Every brace form returns false — but so does the non-brace twin scripts/docs-audit/*.mjs, while scripts/docs-audit/** returns true. So braces are not the discriminator: collapseHint strips */** by design and hintCovers compares on segment boundaries — a deliberate refusal, documented and self-tested, not a defect. It also does not bear on this card: affected-docs.mjs contains 0 occurrences of hintCovers. That flag can be retired.

---

Ruling: C, with A filed as its own card

C — change what --bridge-coverage reports, not what it discovers. Split two causes the report currently prints in the same column and the same words:

• unreachable because discovery missed an in-repo registrar — rest, runtime, i18n, storage. Remediable.
• unreachable because the surface has no in-repo registration site at all, being upstream-declared and catch-all-mounted — auth, 56 of 56. Structural, and not remediable by any discovery change.

This is affected-docs.mjs's own #9747 rule — a recognizer narrower than the repo must report "unrecognised" rather than render as a verdict — applied to the population that rule was written for.

Why C rather than A or B:

• The incidents decide it. [finding] sys_member "Add Member" action targets POST /organization/add-member, which better-auth 1.7.0-rc.2 never mounts (server-only) — on multi-org there is NO remaining UI path to attach an existing user to an org #9941 / docs: the newly mounted POST /organization/add-member is undocumented — and it is the ONLY multi-org path to attach an existing user #10050 were auth routes mounting while their documentation gap shipped silently. C ends exactly that silence. A buys reach on storage and i18n, which were never the incident, and leaves auth at 56 of 56.
• The conflation is what caused this investigation. Today auth's 56 of 56 reads identically to rest's 46 of 87, as one remediable cause. That misreading is what aimed the card at discovery — and cost a full dev cycle plus a wrong PM ruling to undo. C removes it at the source.
• A quietly widens what counts as evidence. It redefines "registrar" to include packages/spec Zod contract declarations (5 files), and admits 3 non-registrars: packages/qa/dogfood/test/fixtures/endpoint-policy-fixture.ts, packages/spec/src/benchmark.bench.ts, and packages/spec/src/conversions/registry.ts (whose /api/v1/health is a connector-action input in an automation fixture, not a route). isTestFile excludes neither test/fixtures/*.ts nor *.bench.ts. Handing a future author three false positives to hand-maintain is option 1's defect one level up — the thing my own claim comment warned against.
• B alone leaves the silence in place, which the incidents say is not acceptable.

A is a real change and gets its own card, because it moves a published figure for a reason this card never asked about and contains a genuine contract question — is a Zod contract declaration a registrar? — plus the three false positives to resolve first. Filing it now.

⚠️ Triage: this changes the deliverable you graded. Your grading said "extend the registrar discovery so auth-plugin.ts (and its class) is reachable". That is now measured impossible, not merely hard. I am reading your intent (stop the auth doc-gap silence) as still binding and serving it through the only mechanism that can, rather than parking the card. If you disagree, the card is yours to re-grade and I will stand down — flagging it rather than letting the change pass unremarked.

Re-dispatching with scope C.
