• 1.lowPassive discovery overwrites abandoned verify cleanup, leaving the cancelled session livesource/src/world/auth.ts:309

        if(abandoned||uncertain){this.gen++;this.lifecycle.cancel();this.cancelOwners('lock-reconcile');

  OPEN; Audit9 Low3 is only PARTIAL. providerChanged('discovery') treats every retained owner as current uncertainty and calls cancelOwners('lock-reconcile'). AuthLifecycle.abandon unconditionally changes the reason even when already abandoned with stop/context-switch. The late verify then goes through reconcileLockedOwner and releases the owner without retrying its deferred nonce logout.

  A stopped or genuinely switched-away B session remains live after a transport-failed first cleanup. This violates preserved original-operation nonce responsibility; no signature bypass, cross-account privilege or foreign-session revocation demonstrated. Filter discovery to current-life owners and prevent passive lock reconciliation from downgrading an existing revoking disposition; preserve legitimate same-lifetime lock-to-stop promotion and cleanup retry/idempotence.

• 2.infoCandidate-cap ranking uses the stale request clock and omits a still-eligible seatsource/server/ownership.ts:262

          const order=(id:string)=>rank(agents.get(id),sightings.get(id),req.now);

  OPEN adjacent temporal consistency defect. best() awaits owner-specific sightings but ranks with req.now, although home() now correctly counts at the live clock. With over 256 registered candidates, seats expiring during the wait tie with the still-recent seat and lower IDs crowd it out. Both keepIndex at line273 and the proof cut at line295 inherit the stale ranking.

  The result is partial/unavailable, not false complete-empty or forged ownership.

  Info: extreme-household availability/selection inconsistency; no additional RPC amplification or unauthorized owner rights. Sample current() once after the sightings await for the ranking, preserving original index/proof producer timestamps and all caps.

  OPEN adjacent display consistency gap; the original Audit9 Low1 final household authority and lane fixes remain effective. assets() awaits world/sightings then passes req.now to status; its Worker caller server/auth.ts:735 supplies no live clock.

  PARTIAL Audit9 Info5: dot/suffix filenames are fixed, but the route-prefix exemption treats whitespace as a route terminator. A bare local filename whose initial segments spell an allowed route bypasses the conservative remainder-of-line masking rule. Quoted paths mask correctly.

  This is an opt-in diagnostic redaction policy gap, not demonstrated production leakage or an Auth vulnerability. Require an unambiguous complete route token before exempting it, or explicitly narrow the claimed spaced-path guarantee and accept that limit. Preserve exact route/query/subroute identifiers, URLs, relative identifiers and replay structure.

   #1499Audit flowClaude3 findings · 1 low

   Everything is verified and the findings file validates against the tree. Here is the closure report.

   Summary and verdicts

   SOURCE-CLOSURE: BLOCKED (one new Low in the Low3 sibling path). The five Audit9 items are closed as bounded on this exact pin, and the reviewer rerun reproduces every TEAM count. But the Low3 fix was applied only to the account-change path. The passive provider-discovery path still treats old-lifetime verify owners as this lifetime's, relabels them, and loses their nonce cleanup. That is reproducible with the shipped fixtures.

   RELEASE-READINESS: UNKNOWN. This source was not deployed. Offline closure measures nothing about Cloudflare, browsers, providers, cookies, ERC-1271, D1, WAF, limiters, process death or cross-isolate behavior.

   Findings are in .imd-findings.json at the repository root (one Low, two Info). Passing tests and Low/Info labels are not certification or zero-vulnerability proof.

   Audit9 item	Mechanism reviewed	REVIEWER result	Verdict
   Low1	Live post-await clocks for final eligibility and lane (ownership.ts:351-358)	25 formal cases pass. checkedAt, index read_at and producer timestamps preserved. Rollback/NaN/Infinity give 503, no amplification. Adjacent gap: public assets() still uses the entry clock (ownership.ts:371), reproduced, display-only. best() ranking also uses req.now but only matters above 256 candidates.	CLOSED (bounded), Info adjacent
   Low2	New lifetime clears public account before the first fenced reply (auth.ts:264, auth.ts:283-298)	A-to-B, locked and no-provider restarts keep cookie A, zero logouts/prompts. Early click obtains a real grant. Late empty reply is dropped by the gen fence. B-to-A cleanup and passive replacement fences hold. No counterexample found.	CLOSED (bounded)
   Low3	Current-life owner filter in accountChanged (auth.ts:595)	The audited sequence passes: first accountsChanged(C) does not revoke row A, C-to-D keeps authority, server refuses nonce logouts with a non-matching token (server/auth.ts:632-640). New Low: providerChanged('discovery') (auth.ts:308-309) counts old-life owners and relabels them to lock-reconcile, so the stop-abandoned verify's nonce logout is never retried and the committed row stays live.	PARTIAL
   Info4	CLI minimization through the validated writer (replay-auth-trace.mjs:16-25)	Verifier 19/19 locally with real file symlinks. Input bytes survive the junction alias collision. Case-variant spelling on case-insensitive volumes passes the lexical identity check (line 19); not reproducible on this Linux host, reported as Info. Controlled-root assumption and no concurrent ancestor-swap guarantee accepted.	CLOSED (bounded), UNKNOWN on case-insensitive volumes

   • lowPassive provider discovery in a new lifetime relabels an old lifetime's retained verify owner to lock-reconcile, dropping its nonce cleanupsource/src/world/auth.ts:308

     Audit9 Low3 was closed by filtering retained owners by the current lifetime in accountChanged (src/world/auth.ts:595, 'Old lifetimes retain their own nonce cleanup, never this lifetime's account-change intent').

     The parallel path providerChanged('discovery') (auth.ts:304-314) was not updated: uncertain counts retainedOwners of every lifetime, and cancelOwners('lock-reconcile') (auth.ts:236) calls AuthLifecycle.abandon, which unconditionally overwrites cancellationReason (authLifecycle.ts:103) from 'stop' to 'lock-reconcile'.

     From then on every settle/retry of that old owner is routed through the lock path: revokeAbandoned (auth.ts:632) and settleCancelledOwner via planCleanup('verify-settled') (authCleanup.ts:19) both become reconcileLockedOwner, which only reads the cookie and releases the owner (authLifecycle.ts:94-97) and 'never revokes a committed session'.

     The stop-abandoned verify's nonce-specific logout is therefore never retried, the committed session row stays live, and the restarted UI adopts it from the cookie. In the identical sequence without the discovery event, cancellationReason stays 'stop', the retry logout is sent with expectedNonce and the row is revoked (REVIEWER control run).

     No cross-account authority is gained and no foreign row (e.g. a replacement cookie A) is revoked by this path, because planCleanup('lock') with a RETAINED owner yields 'reconcile'; the defect is the lost old-lifetime nonce cleanup that Audit9 Low3's closure says is preserved.

     Fix: in providerChanged('discovery') compute uncertain from owners whose owner.life===this.life (as accountChanged does) and let cancelOwners/abandon skip owners that are already abandoned with a terminal reason ('stop'/'explicit-signout'), or have abandon() refuse to downgrade a non-lock reason to 'lock-reconcile'.

     whole finding

     Offline fixtures only (tests/auth-r7-fixtures.mjs: real AuthClient, real Worker, migration-backed SQLite).

     Sequence: (1) tab q with provider B; ready; q.signIn(); hold the /api/auth/verify response at intercept after headers (cookie B is already set).

     (2) q.stop(): teardown runs automaticCleanup('stop') -> planCleanup -> verify-owner -> revokeAbandoned sends POST /api/auth/logout {expectedNonce:B.nonce}; make that request fail at the network (beforeSend throws). lifecycleSnapshot.cleanup.cancellationReason==='stop'.

     (3) q.restart(); session read restores PRESENT B.

     (4) Fire a passive discovery: deps.provider() returns a different provider object for the same account B; q.notifyProvider('discovery').

     Observed: cancellationReason becomes 'lock-reconcile' although the owner belongs to the previous life.

     (5) Release the held logout (fails, ok=false; cleanupDone leaves it RETAINED, inFlight=false).

     (6) Release the verify response; the old signIn continuation calls settleCancelledOwner.

     EXPECTED (per Low3 closure): planCleanup('verify-settled') -> verify-owner -> second POST /api/auth/logout {expectedNonce:B.nonce} -> 204 -> sessions row for B revoked_at set; client session null.

     ACTUAL: plan 'reconcile' -> reconcileLockedOwner -> GET /api/auth/session -> owner RELEASED; nonce logouts total 1 (the failed one), no retry; sessions row for B revoked_at NULL; client state.session = B.

     Both: prompts 1, challenge 1, verify 1, address-asserted logouts 0, broadcasts 0, session reads 4.

   • infoPublic assets view applies the inclusive 24h counting rule at request-entry time, not after the D1 sightings wait, unlike the Low1-fixed home()source/server/ownership.ts:371

     Audit9 Low1 moved home()'s final eligibility to a live post-await clock (ownership.ts:357-359). assets() still evaluates the same counts predicate (ownership.ts:151, 'One predicate ... so no second copy of the 24 h rule exists') with req.now after awaiting world() and the seat_presence D1 read (ownership.ts:367-371), and the Worker passes no clock to it (server/auth.ts:735 passes only now).

     A sighting that crosses the inclusive 24 h boundary while D1 waits is reported as counts:true in the public wallet view while /api/me/home for the same row and the same clock answers counts:false.

     This grants nothing: assets is the unverified public roster view, the answer is cached public max-age=300, and owner rights come only from home(). It is reported because the task asks for adjacent live-clock counterexamples and because the response is dated by lastOnlineAt/fetchedAt as if current.

     Fix: pass clock:()=>clock(deps) from the assets route and sample it after the sightings await (as home() does), or document the entry-time rule for the public view.

   • infoReplay CLI input/output identity check is lexical, so a case-variant spelling of the input path on a case-insensitive volume is accepted as a separate output and overwrites the inputsource/scripts/replay-auth-trace.mjs:19

     Info4's alias control resolves the input with realpathSync and compares it lexically with resolve(out) (replay-auth-trace.mjs:16-19). Symlink and junction aliases are caught because realpath canonicalises them and the store's validate() refuses link components (tests/auth-artifacts.mjs:64).

     A case-variant spelling is a different alias: on a case-insensitive filesystem (macOS APFS default, or a Linux casefold directory) tmp/Store/core500-failure-original.json names the same file as tmp/store/core500-failure-original.json, path.relative on POSIX is case-sensitive so the check passes, Node's JS realpathSync preserves the caller's spelling so validate() (auth-artifacts.mjs:64 realpathSync(cursor)!==cursor) also passes, and write() renames the temp file over the input's directory entry (auth-artifacts.mjs:97).

     The trace was already read (line 27), so the replay runs and the minimized output replaces the original failure trace: input bytes are not preserved. Windows is not affected because win32 path.relative compares case-insensitively; Linux ext4 without casefold is not affected.

     NOT reproduced here: this checkout was run on case-sensitive Linux ext4 where the variant spelling creates a separate directory. Locally controlled root assumption is unchanged; impact is loss of the operator's own replay input, no Auth effect.

     Fix: compare file identity, not spelling: lstat the resolved output (when it exists) and reject if dev/ino equal the input's, or make the store's write() refuse when the final path's inode equals a caller-supplied protected inode.

     whole finding

     On a case-insensitive volume (macOS default APFS) from source/: create a valid trace as scripts/verify-artifact-closure.mjs cliInput does, at tmp/store/core500-failure-original.json (sha256 S0); run node scripts/replay-auth-trace.mjs --replay tmp/store/core500-failure-original.json --minimize tmp/Store/core500-failure-original.json.

     Expected: exit 1 with ARTIFACT_REJECTED 'minimized output must be separate from the replay input' and sha256(input)==S0.

     Predicted actual (from the code path; unverified on this Linux host): exit 1 with HARNESS-CAUSAL, no ARTIFACT_REJECTED, and tmp/store/core500-failure-original.json now holds the minimized JSON (sha256 != S0).

     On this Linux ext4 host the same command creates tmp/Store/ as a distinct directory and the input is preserved (REVIEWER did not run it; H-C5 in the verifier covers only the symlink alias).

   Summary

   The exact candidate at c2f21a9 closes all five Audit9 blockers and both adjacent counterexamples. I reproduced the supported runner (659/659), the artifact suite (28/28) and the standalone verifier (19/19) on a fresh Linux checkout with locked viem 2.56.9 and Node 24.21.0, all exit 0 with empty stderr and no skip/todo/cancel. All 143 selected source hashes match the Submission10 manifest and SHA256SUMS verifies 277/277. The pin's parent is the official public 347268a. Nothing from prior Auth/ownership/artifact boundaries reopened in my probes.

   Beyond the five items, I found one new Low and three Info defects inside the same mechanisms. The Low: a passive provider discovery rewrites an already-abandoned verify owner's cleanup disposition to lock-reconcile, so when the first nonce revocation failed at transport, the switched-away account's committed session is never revoked and the page adopts it as a mismatch session. The Infos are a residual request-start clock in the cap ranking and the public assets view, and two sanitizer regex gaps unrelated to the route-prefix issue.

   SOURCE-CLOSURE: BLOCKED (new Low in src/world/auth.ts; the five Audit9 items themselves are CLOSED bounded). RELEASE-READINESS: UNKNOWN (source not deployed; no production Cloudflare/browser/provider/D1 measurement exists).

   • lowPassive provider discovery downgrades an already-abandoned verify owner's cleanup disposition to lock-reconcile, so a transport-failed nonce revocation is never retried and the switched-away account'ssource/src/world/auth.ts:309

     providerChanged('discovery') calls cancelOwners('lock-reconcile') over every retained owner (auth.ts:236), and AuthLifecycle.abandon (authLifecycle.ts:102-104) overwrites o.cancellationReason even when the owner is already abandoned with a revoking disposition ('context-switch' from a genuine accountsChanged, or 'stop' from teardown). The comment at auth.ts:235 says the cancellation disposition belongs to the original operation.

     After the flip, revokeAbandoned (auth.ts:632) and settleCancelledOwner (auth.ts:617-619) route the owner to reconcileLockedOwner, which only reads the cookie and releases the owner; the pending nonce logout that cleanupDone deferred until response observation (authLifecycle.ts:113) is never dispatched again. A passive discovery event, which by design has no switch authority, thereby cancels a cleanup that an authoritative account switch had ordered.

     The same unfiltered cancelOwners also reaches old-lifetime owners (uncertain is not filtered by owner.life, unlike accountChanged's currentOwners at auth.ts:595); for those the outcome is the same release-without-revocation.

     Minimal fix: never downgrade an abandoned owner's disposition, e.g. in abandon() return false when o.abandoned is already true (or only allow lock-reconcile on owners that are not yet abandoned), and filter cancelOwners('lock-reconcile') to owners of the current life.

     (2) accountsChanged([C]) -> accountChanged: owner abandoned with cancellationReason 'context-switch', revokeAbandoned dispatches POST /api/auth/logout {expectedNonce}; the transport fails before dispatch (synthetic TypeError), so no server write; cleanupDone leaves the owner RETAINED/abandoned/not inFlight (snapshot: status RETAINED, reason context-switch).

     (3) providerChanged('discovery') with a new provider object for the same account C -> snapshot: status RETAINED, reason 'lock-reconcile'.

     EXPECTED (control run identical except step 3 omitted): second nonce logout dispatched when the body lands -> 204, B row revoked_at = now, cookie cleared, GET /api/auth/session signedIn:false, client status 'connected', logout count 2.

     Same outcome when the first life is stopped instead of switched (stop disposition flipped after restart + discovery): B row stays revoked_at NULL and the new life adopts B as signedInNoHouse, whereas the control run retries the nonce logout.

   • infoCANDIDATE_CAP ranking after the seat_presence await still uses the request-start clock, so a seat that counts at the live clock can be cut in favour of seats whose sightings expired during the D1 waitsource/server/ownership.ts:262

     Audit9 Low1 moved the final eligibility sample and the lane sample to the live clock (home(), lines 351 and 357), but the N-3 cap ranking in best() evaluates rank(...) with req.now after awaiting this.sightings (line 260-263). The same stale-ranked cut is persisted by keepIndex (line 273). The comment at line 148-150 states that one predicate exists so no second copy of the 24 h rule exists; the clock domain differs here.

     Effect is limited to households with more than CANDIDATE_CAP (256) registered candidates (largest holder observed is 20), and only when sightings cross the inclusive boundary during the D1 wait.

     Fix: pass the live clock (current()) to rank/order in best(), or compute the cut with the same post-await sample that status() uses.

     wallet-harness setup, real Worker and node:sqlite: an address owns seats 1..257 (roster owners[] and chain ownerOf agree; every seat is a registered agent with a decimal agentId; none online). seat_presence: seats 1..256 last_online_at = now-86400000 (exact inclusive boundary); seat 257 last_online_at = now-1000.

     Control with 0 ms delay: eligible 256, size 'xl', recheck 'partial' (seat 257 cut by id among 257 rank-0 seats, as designed).

   • infoPublic assets view evaluates the 24 h counting rule with the request-start clock after awaiting roster and seat_presence readssource/server/ownership.ts:371

     assets() awaits world() and sightings() and then calls status() with req.now, the same pre-await pattern Audit9 Low1 removed from home(). The route passes no clock at all (server/auth.ts:735 builds the request without clock), so even a clock-aware status() would not help without also threading the clock.

     The view is unverified, carries no owner rights and is served with Cache-Control public, max-age=300, so the impact is a displayed counts/reason flag that can be up to one D1-wait stale; no eligibility authority is affected.

     Fix: sample a live clock after the awaits (and pass clock from the route) or document the view as request-dated.

     wallet-harness setup: seat 7 owned by address X, registered agent, offline; seat_presence row (7, X, now-86400000).

     The 'SELECT token_id,last_online_at' read advances the injected clock by 1 ms.

     GET /api/wallet//assets.

     ACTUAL: 200, seats[0].counts true, reason absent, lastOnlineAt now-86400000, Cache-Control public, max-age=300.

     EXPECTED at the live clock (now+1): counts false, reason 'offline-24h' (the same input through GET /api/me/home with the same delay yields counts false).

     Control with 0 ms delay: counts true is correct (inclusive boundary).

   • infoNetwork-URL preservation in the artifact sanitizer keeps absolute local paths when a file: URL is preceded by a dotted/hyphenated token or when an absolute path directly follows a URL without whitespasource/tests/auth-artifacts.mjs:11

     The negative lookahead (?!file:) is only applied at the scheme start, but the scheme class [A-Za-z0-9+.-]+ admits '.' and '-', so 'module.file://' or 'x-file://' is classified as a network URL and its path is preserved verbatim in persisted artifacts. Separately, the URL tail [^\s"'<>]+ consumes ',/root/...' or '(/root/...)' that follows a URL with no whitespace, so that absolute path is never seen by sanitizeBare.

     These are not the Audit9 Info5 route-prefix issue (which is closed: '/api/auth/session.log' and its quoted/bare variants are masked) but they are residual gaps in the stated 'arbitrary roots' redaction guarantee.

     Fix: require the scheme to be exactly file-free (e.g. (?![A-Za-z0-9+.-]*file:) or exclude '.' and '-' before a file: match) and terminate the URL token at ',' '(' and ')' or run sanitizeBare on the URL tail after the first path segment.

   • infoAudit9 Low1 adjacent: public /api/wallet/:a/assets still evaluates the 24h counting rule at request-start time after its D1 awaitsource/server/ownership.ts:371

     Audit9 Low1 was closed in home() by sampling the live clock after the sightings/lane awaits (ownership.ts:351 laneNow, :357 now). The sibling public view assets() runs the same shared counts() predicate (ownership.ts:151) through status() but passes req.now, the request-entry time, after awaiting this.world() and this.sightings().

     A seat_presence sighting that crosses the inclusive 24h boundary during the D1 wait is therefore reported counts:true (no reason) by /api/wallet/:a/assets while /api/me/home for the same owner, seat and instant reports counts:false, reason:'offline-24h'.

     The server route passes no clock for assets (server/auth.ts:735: {chain,db,now,waitUntil,budget}), so the fix is bounded: pass clock:()=>clock(deps) at auth.ts:735 and use req.clock?.()??req.now in assets() after the sightings read, as home() does.

     Impact is display-only: assets is explicitly the unverified public roster view, grants no owner rights, and is served with Cache-Control public max-age=300, so a 1 ms boundary disagreement is immaterial to authority. This is an Info-level consistency gap adjacent to Low1, not a reopening of it: home() is correct.

     Reproduced by REVIEWER offline with the real Worker and migration-backed SQLite: synthetic owner with seat 7 (agent '707', offline), seat_presence last_online_at = now-(86400000-1); db.prepare wrapper advances the injected clock by D ms when the first 'SELECT token_id,last_online_at' completes. D=0,1: both views counts:true (age <= 86400000). D=2: assets counts:true, home eligible 0 / counts:false (age 86400001).

     D=5000: assets counts:true, home counts:false (age 86404999).

   • infoAudit9 Info4 adjacent (unverified on Linux): replay input/output collision check is case-sensitive, so on a case-insensitive filesystem a differently-cased parent directory spelling bypasses it and thsource/scripts/replay-auth-trace.mjs:19

     The Audit9 Info4 adjacent control requires that differently spelled input/output paths resolving to the same input be rejected. The CLI canonicalizes only symlinks: inputPath=realpathSync(resolve(file)) and output=resolve(out), then compares with path.relative.

     Node's JS fs.realpathSync does not canonicalize letter case and path.posix.relative is case-sensitive, so on a case-insensitive filesystem (macOS APFS/HFS+ default, or an ext4 casefold directory) --replay tmp/store/core500-failure-original.json --minimize tmp/Store/core500-failure-original.json passes this check. createArtifactStore({requestedDir:'tmp/Store'}) then also passes: inside(allowed,directory) is satisfied ('Store' is under 'tmp'), each chain component lstat()s to an existing non-symlink directory and realpathSync(cursor)===cursor because realpathSync returns the caller's spelling, file(name) accepts 'core500-failure-original.json' (namespace regex), regular(path) sees the input's own regular inode, and write() finishes with renameSync(temp,path), which on a case-insensitive directory replaces the input's directory entry.

     Result: the replay input is overwritten by the minimized artifact, the exact outcome the collision check exists to prevent.

     On Windows path.win32.relative compares case-insensitively, so the check holds there; on Linux (this review environment) paths are case-sensitive, so the scenario cannot occur and was NOT reproduced here: this is a code-reading lead with the concrete failing input stated, severity Info (local developer tool, controlled root, data-loss of a tmp artifact, no Auth impact).

     A robust fix compares filesystem identity rather than spelling: lstat both paths after resolving and reject when dev/ino match (the store already has same(a,b)), or use realpathSync.native on both sides and additionally reject when the output's final entry stats equal the input's.

     Control: the same two commands with --minimize tmp/store/core500-failure-original.json (same spelling) are rejected as the existing test 'Audit9 minimization CLI never overwrites its replay input' shows.

   All evidence is in hand: 25 files executed with per-file counts summing to 659, findings file validated against the tree, and git working tree unchanged. Here is the review.

   Summary and verdicts

   SOURCE-CLOSURE: BLOCKED (bounded). All five Audit9 items are closed as specified at this pin, and nothing from Audit8/R8/R7 reopened. One new Low sits inside the requested mechanism 2/3 reverse controls: a passive provider discovery in a new lifetime rewrites a stopped lifetime's retained verify owner from stop to lock-reconcile, so the committed session is never revoked by its nonce. Two Info gaps are non-blocking. If the requester accepts the Low as a policy limit, the remaining matrix is PASS.

   RELEASE-READINESS: UNKNOWN. This source was not deployed. Offline tests say nothing about Cloudflare, browsers, providers, cookies, ERC-1271, M1 authorization, D1, WAF, limiters, upstreams, process death or cross-isolate behaviour. The type-check fails only on withheld frontend modules, so build evidence is unavailable, not failing.

   REVIEWER reproduced every TEAM claim independently on Linux, Node v24.21.0, locked viem 2.56.9: review 659/659, verifier 19/19, exit 0, zero fail/cancel/skip/todo, no stderr. The same-evaluator vulnerable baseline rebuilt from parent 347268a gives 40/64 and 14/19 with 5 ERR_ASSERTION, matching TEAM exactly. The four runnable Audit9 original reproductions now fail at their vulnerable-behaviour assertions on this candidate. All 143 manifest hashes match the checkout.

   Findings written to .imd-findings.json (3 findings, snippets verified against the tree):

   • Low, source/src/world/auth.ts:308. providerChanged('discovery') derives uncertain from every retained owner and cancelOwners re-disposes all of them. With cookie B kept, control revokes B (204, row revoked_at set, client visitor, owner CONSUMED). With discovery, no second nonce logout is sent, owner RELEASED, B row stays live, new lifetime shows B as mismatch with account C, and a lock/reconcile plan with the old flowId is recorded. Fix: filter by owner.life===this.life as line 595 does.
   • Info, source/server/ownership.ts:371. assets() still passes req.now to status() after the sightings await; the route also injects no clock. Sighting age 86400001 ms yields counts=true, the next request says false. Public unverified view, no authority, no index/budget/RPC.
   • Info, source/tests/auth-artifacts.mjs:17. A route token followed by whitespace is exempt, so /api/auth/session private.log persists verbatim and /api/auth/session (private)/x.ts leaks its middle segment. Quoted and Node-error forms mask correctly. Policy-boundary gap on synthetic names.

   Accepted limits noted, not reported: best() ranking inside proof() uses req.now for the N-3 cut, which can only under-count with recheck:'partial'; the server's conditional nonce logout returns 409 once another context's cookie replaces B, by design.

   • lowPassive provider discovery in a new lifetime treats a stopped lifetime's retained verify owner as current uncertainty and rewrites its 'stop' disposition to 'lock-reconcile', dropping the nonce revocasource/src/world/auth.ts:308

     Audit9 Low3 filtered accountChanged() to owners of the current lifetime (line 595), but providerChanged('discovery') at line 308 still derives uncertain from every retained owner, and cancelOwners('lock-reconcile') at line 309 iterates all of them (line 236), so a detached old-lifetime owner whose cancellationReason is 'stop' is re-labelled 'lock-reconcile' by an event in a lifetime it does not belong to.

     The new lifetime also bumps gen, clears its public account and records a 'lock'/'reconcile' cleanup plan carrying the old owner's flowId (observed plans:[{eventId:2,reason:'lock',kind:'reconcile',flowId:1}]).

     When the old lifetime finally observes B's verify response, settleCancelledOwner() plans by the rewritten reason: planCleanup('verify-settled') returns 'reconcile' instead of 'verify-owner', reconcileLockedOwner() runs a canonical read and releases the owner, and no expectedNonce logout is ever sent again.

     The stopped lifetime's policy ('Security cleanup still runs after teardown', 'Cancellation disposition belongs to the original operation') is silently replaced by a cookie reconcile.

     Reverse controls hold: cookie A is never revoked (no expectedAddress logout), B's cookie-A collision still yields 409 ACCOUNT_CONTEXT_CHANGED on the server, the same-lifetime lock-then-stop ordering still ends in 'stop'.

     Fix: compute uncertain from retainedOwners.filter(o=>o.life===this.life) and let cancelOwners only re-dispose owners of the current lifetime (or never downgrade a 'stop' disposition to 'lock-reconcile'); keep the same-lifetime lock-reconcile behaviour.

   • infoPublic assets view still evaluates the 24 h counting rule at request-start time after the D1 sightings await (Audit9 Low1 fix not applied to assets())source/server/ownership.ts:371

     home() now samples a live clock after its awaits (lines 351/357), but assets() awaits this.world() and this.sightings() (line 369) and then passes req.now (request start) to status() at line 371, so a seat whose owner-specific sighting crosses the inclusive 24 h boundary during the D1 read is reported counts=true (no reason) although an immediately following request reports counts=false/offline-24h.

     The route /api/wallet/:address/assets (server/auth.ts:735) also passes no clock, so even a req.clock?.()??req.now fallback would not help there. This is the public, unverified roster view (no ownerOf, no session, no authority, Cache-Control public max-age=300), so it is Info: inaccurate public counting/size hints, not an eligibility or authorization defect, and no index/budget/RPC amplification (0/0/0 per request).

     Fix: sample the clock once after the sightings await (pass clock:()=>clock(deps) from the assets route and use it for status(), like home()), preserving fetchedAt and the inclusive comparator.

   • infoRoute-prefix exemption still lets a space-separated bare path that starts with an exact route survive persisted diagnosticssource/tests/auth-artifacts.mjs:17

     The Audit9 Info5 fix stops dots and punctuation from inheriting a route exemption, but a route token followed by a space or tab is still treated as a complete route and the rest of the segment as prose.

     The module's own policy for bare absolute paths (lines 19-21) is that a path may contain spaces or parentheses and that the remainder of the segment is conservatively removed because its end is ambiguous; a bare path whose first segments spell an exact route is the one case where that policy is not applied, so /api/auth/session private.log persists unchanged and /api/auth/session (private)/x.ts persists its middle segment ('(private)') with only the trailing '/x.ts' masked.

     The quoted form "/api/auth/session private.log" and Node fs error messages (which quote paths) are masked correctly, so realistic diagnostics are covered; this is an Info policy-boundary gap on synthetic filenames, not evidence of production leakage, and exact routes, query/subroute tokens, URLs, relative IDs and replay structure are preserved.

     Fix options: apply the route exemption only when the route is the whole segment or followed by end/punctuation (not whitespace plus more text), or when followed by whitespace require the next token not to look like a path continuation (contains '/' or '\' or a file extension); accept the trade-off that prose like 'GET /api/auth/session returned 429' would then be masked, or keep the current behaviour as a documented accepted limit.

   Low1 — post-await eligibility	CLOSED original; PARTIAL broader mechanism	All 25 formal cases passed: inclusive 24-hour boundaries, both enrichment reads, refresh lanes, strict proof TTL, invalid clocks and recovery. Final eligibility preserves proof/index timestamps. Two adjacent Info defects remain: stale candidate-cap ranking and public-assets counting. Final-clock implementation.
   Low2 — same-client restart	CLOSED, bounded	Restart clears prior identity; first B/empty/no-provider observations preserve cookie A. Held initial replies plus early clicks obtain current explicit grants; late empty replies cannot erase B. Genuine B-to-A cleanup succeeds when its completion is awaited. One timing-sensitive suite assertion is detailed below. Lifetime/binding fences.
   Low3 — detached verify owner	PARTIAL; Low finding OPEN	The original first-C event preserves A’s SQLite row; current C-to-D cleanup and delayed-cookie reconciliation pass. However, passive discovery can overwrite an abandoned owner’s disposition and suppress its nonce-cleanup retry. Current-life account guard, unfiltered discovery path.
   Info4 — replay output containment	CLOSED, bounded	Actual CLI controls reject unsafe final/parent links, nonregular targets, namespace/root escapes and input collisions. Separate output through an aliased input preserves both input views; default replay persists nothing new. Linux symlinks were exercised; Windows junction behavior remains TEAM evidence. CLI validation/writer.
   Info5 — route-prefix filename masking	PARTIAL; Info finding OPEN	Required .log, .backup, .private.json and attached suffix variants are masked, with exact protocol/replay controls preserved. Bare filenames containing spaces still inherit the route exemption and survive persistence. Exemption and masking policy.

   • lowPassive discovery overwrites abandoned verify cleanup, leaving the cancelled session livesource/src/world/auth.ts:309

     OPEN; Audit9 Low3 is only PARTIAL. providerChanged('discovery') treats every retained owner as current uncertainty and calls cancelOwners('lock-reconcile'). AuthLifecycle.abandon unconditionally changes the reason even when already abandoned with stop/context-switch. The late verify then goes through reconcileLockedOwner and releases the owner without retrying its deferred nonce logout.

     A stopped or genuinely switched-away B session remains live after a transport-failed first cleanup. This violates preserved original-operation nonce responsibility; no signature bypass, cross-account privilege or foreign-session revocation demonstrated. Filter discovery to current-life owners and prevent passive lock reconciliation from downgrading an existing revoking disposition; preserve legitimate same-lifetime lock-to-stop promotion and cleanup retry/idempotence.

   • infoCandidate-cap ranking uses the stale request clock and omits a still-eligible seatsource/server/ownership.ts:262

     OPEN adjacent temporal consistency defect. best() awaits owner-specific sightings but ranks with req.now, although home() now correctly counts at the live clock. With over 256 registered candidates, seats expiring during the wait tie with the still-recent seat and lower IDs crowd it out. Both keepIndex at line273 and the proof cut at line295 inherit the stale ranking.

     The result is partial/unavailable, not false complete-empty or forged ownership.

     Info: extreme-household availability/selection inconsistency; no additional RPC amplification or unauthorized owner rights. Sample current() once after the sightings await for the ranking, preserving original index/proof producer timestamps and all caps. Exact c2f21a9, real Worker/viem2.56.9/SQLite, synthetic offline fixtures.

     OPEN adjacent display consistency gap; the original Audit9 Low1 final household authority and lane fixes remain effective. assets() awaits world/sightings then passes req.now to status; its Worker caller server/auth.ts:735 supplies no live clock. Sighting expiry during D1 yields counts:true in this public unverified roster while the next request is false.

     Info only: public max-age=300 display hints, not owner authority; no index/budget/RPC amplification. Thread the live clock from the route and sample after awaited enrichment (account for later character I/O if enabled), without changing fetchedAt or the inclusive comparator. Synthetic D1 delays do not establish production effects.

   • infoBare route-prefix filenames containing spaces survive persisted artifact redactionsource/tests/auth-artifacts.mjs:17

     PARTIAL Audit9 Info5: dot/suffix filenames are fixed, but the route-prefix exemption treats whitespace as a route terminator. A bare local filename whose initial segments spell an allowed route bypasses the conservative remainder-of-line masking rule. Quoted paths mask correctly.

     This is an opt-in diagnostic redaction policy gap, not demonstrated production leakage or an Auth vulnerability. Require an unambiguous complete route token before exempting it, or explicitly narrow the claimed spaced-path guarantee and accept that limit. Preserve exact route/query/subroute identifiers, URLs, relative identifiers and replay structure.

     Reproduced by reading the actual file written by createArtifactStore, on exact c2f21a9 with Node24.21.0.
