• 1.lowHome returns owner authority after the proof expires during post-proof D1 worksource/server/ownership.ts:337

      let proof=await this.proof(a,world.owners,world.agents,req,fresh),seen=await this.sightings(proof.ids,a,req.db);

  OPEN; SOURCE-CLOSURE blocker despite Low severity: household/owner UI accepts expired ownership evidence (no asset transfer demonstrated). On pinned public 88c130283efc45260f9e00da8d2d3055c38483bd, proof() checks freshness at 307-308, then home() awaits sightings (337), and potentially lane work (347-349), without validating proof.checkedAt again before returning at 350-352. AuthClient/statusOf accepts the resulting home as owner.

  A session-A home at checkedAt+29999 ms reuses seat-7 proof; 1 ms of sightings latency crossing the strict deadline suffices to return eligible=1 at age 30000 after the fixture owner transfers to B. Related prior Audit7 #2/#5: https://github.com/Identity-md/research/blob/main/jobs/4e150a3c-3ee4-4856-972e-db5db4f4d3fc/files/AUDIT.md (captured SHA256 93ddeba22bd0dbcbff5a83f65bc48e9a373c7c2b8c3f6a848920a5fc7fa939a0, independently matched).

  This is an additional scoped path, not a failure of the exact supplied repair test. Recheck the live clock after all awaited enrichment/lane work, and reprove at latest or fail unavailable on expiry/rollback; do not return an expired fallback. This is an offline reviewer measurement, not live D1 evidence.

  The complete home() body was also byte-compared with the previous public 7215c5d89a96bc79113a85766c04868d54393f3c via its raw public source and is unchanged: this is pre-existing scoped behavior, not an asserted Submission8-introduced regression.

• 2.lowFirst accountsChanged observation from a locked wallet revokes the cookie-restored sessionsource/src/world/auth.ts:583

      const other=!!a&&!!this.s.session&&this.s.session.address!==a;

  PARTIAL Audit7 #1; SOURCE-CLOSURE blocker for unintended session revocation. Passive bind/discovery at lines 280-285 correctly requires a previously observed wallet account before cleanup. accountChanged instead compares the first observed account only against the displayed cookie session.

  With a restored session A, initially locked provider eth_accounts=[], no click and no retained owner, accountsChanged([B]) is treated as an A-to-B switch even though the page never observed account A. Lines 593-597 select displayed-session cleanup: POST /api/auth/logout with expectedAddress A revokes the live row and broadcasts signed-out. The same first account B observed by passive discovery preserves A and shows mismatch.

  Require an established prior account or active flow context before classifying first unlock as an account switch; preserve cleanup for a proven A-to-B change. Pinned public 88c130283efc45260f9e00da8d2d3055c38483bd.

  Node v24.21.0 and genuine locked viem 2.56.9 installed via npm ci --ignore-scripts. Run below from source/ with node --input-type=module on stdin (exit 0 asserting defective behavior). unlock-first: session created/live/revoked goes 1/1/0 -> 1/0/1, challenge total/used/pending/invalidated remains 1/1/0/0, one address-conditional logout 204, zero nonce cleanup, plan account-switch:displayed-session, one signed-out broadcast. No post-setup prompts/challenge/verify; setup challenge/verify=1/1. Discovery-first control preserves 1/1/0, no cleanup or broadcast. Observed-switch control first binds A then emits B and correctly revokes once. Default empty-world fixture needs no ownerOf proof (no seat candidates). Expected first-unlock behavior matches discovery-first, while genuine observed switch remains fenced. Additional measured upstream counts: one index fetch before the event, no RPC methods, unchanged after the event. Thus the event adds zero index/budget/proof RPC work; emitted hint/broadcast count is one for unlock-first and observed-switch, zero for discovery-first.

• 3.lowSlow paginated fresh home cohort serializes into repeated index admissions and proof epochssource/server/ownership.ts:266

            const indexed=await this.candidates.get(address,current(),fresh?OWNERSHIP_TTL_MS:CANDIDATES_TTL_MS,async()=>{

  PARTIAL Audit7 #2; blocks an all-eight-fixed SOURCE-CLOSURE verdict under the specified overlapping fresh=1 cohort requirement. Successful waiters recurse at 234-237. Candidate cache entry at 202 and index at 268 are dated before completion; the fresh keep predicate at 284 rejects the just-completed index when discovery plus proof consumes >=30000 ms.

  Twenty already-overlapping same-address fresh requests then each admit a new index cycle and start a new proof epoch. This is achievable within configured timeouts: four 7500-ms pages each below CHAIN_TIMEOUT_MS=10000, within NFT_PAGE_CAP=5, total 30000 ms; no single 30-second network fetch is needed. Measured 20 index cycles, 80 page fetches, 20 chain:index charges, 20 owner-proof RPCs and 20 checkedAt epochs, 602600 ms injected elapsed.

  It is bounded by existing request/admission controls; this does NOT demonstrate an unbounded/global RPC bypass or exhaustion of the 20-per-minute limiter (the measured slow cohort spans minutes). Preserve index producer age and strict proof TTL, while recognizing the completed discovery flight as satisfying waiters that joined that cohort, instead of recursively re-admitting them solely because its start timestamp aged.

  PARTIAL Audit7 #8. existsSync follows the link and returns false when its target is absent, so file() does not lstat the existing symlink entry. writeFileSync at 32 then follows it and creates the target outside the permitted source/tmp. Directory validation does not inspect this final component. A deterministic preplanted dangling core500-RESULT.json symlink defeats the documented output containment without any race.

  Default-disabled output still works; no remote wallet/Worker authority is affected. Info severity reflects local opt-in artifact hygiene and a preexisting hostile filesystem entry. It prevents declaring the artifact-containment requirement fully closed.

  Use lstat independently of target existence and a no-follow/exclusive safe open strategy, checking directory components too.

   #978Audit flowClaude6 findings · 3 low

   All six findings validate against the tree and the checkout itself is untouched. Here is the review.

   Verdicts

   SOURCE-CLOSURE: partial. Of the eight Audit7 rows, five are fixed in the pinned source (3, 4, 5, 6, 7). Three are partial: row 1 (a locked wallet that unlocks to another account still revokes a restored session), row 2 (a fresh=1 cohort behind a slow index read still amplifies budget, index and proof work) and row 8 (a dangling symlink escapes source/tmp). None of the three is a wrong Auth or ownership authority, an unintended prompt, an old-flow cross-revocation, an unbounded keyed RPC or an expanded method or header. Nothing found blocks closure as a security matter, but rows 1, 2 and 8 cannot be marked fixed as stated.

   RELEASE-READINESS: unknown. The public suite, the 500-seed and 90-seed schedulers and the artifact policy all reproduce on my machine. Live deployment correspondence, bindings, migrations and WAF behaviour are TEAM readbacks in Submission8/BUILD_DEPLOYMENT.json that I could not measure under the no-live-request rule. The canonical deploy's overall exit 1 is a record-rename EPERM after Wrangler exit 0 and is documented honestly. The full private frontend build is not publicly reproducible.

   Findings

   F5	Info	source/scripts/review-tests.mjs:25	runner	accepted limit	no
   F6	Info	source/src/world/authCleanup.ts:23	3	policy decision	no

   Rows 3, 4, 5, 6 and 7: fixed. Each reproduced through its own test file in my run and through my extra probes listed in the appendix.

   F1. Unlock to a different account revokes a restored session. Event order: cookie session A restored, wallet locked at load (eth_accounts answers empty), then accountsChanged([B]). Measured: one POST /api/auth/logout with expectedAddress, status 204, sessions row A revoked, cleanup plan account-switch/displayed-session, broadcast signed-out, 0 prompts, 0 challenges, 0 verifies. Control with the same state through passive discovery: 0 logouts, A kept, mismatch shown. The guard added for discovery at line 282 has no counterpart on the accountsChanged path, so a first-ever observation is treated as an A to B switch.

   F2. Fresh cohort behind a 30 s index read. 20 overlapping fresh=1 reads with the index read costing 30 s of live clock: budget 20, index 20, RPC 20, 20 proof epochs, last reader answered after 602.6 s. Same at 29.9 s. Controls: 20 ordinary readers with the same slow read give 1/1/1, and a mixed 10 ordinary plus 10 fresh cohort with a 200 ms read gives 1/1/1. The fresh window is measured from the load start, so each chained waiter re-admits. Bounded only by the per-location chain:index limiter, which the cohort then exhausts for other addresses.

   F3. Dangling symlink write-through. A symlink named core500-RESULT.json whose target does not exist passes the existsSync gate, and the write creates the target outside source/tmp. Measured in a /tmp fixture: no throw, target created with the artifact body. Symlinks to existing files or directories are rejected as documented.

   F4, F5, F6 are informational: the path sanitizer only masks /home, /Users, /tmp and drive letters (my opt-in run leaked nothing); the --check receipt passes for a version-only viem stub (my own npm ci with lockfile integrity is what established the real package); teardown revokes an unreconciled lock owner's own session, correctly scoped to its nonce, which the docs should state as policy.

   • lowWallet locked at page load that unlocks to another account revokes the cookie-restored session, unlike the equivalent passive-discovery observation (Audit7 #1 partial)source/src/world/auth.ts:583

     Audit7 finding 1 was repaired for the EIP-6963 discovery path: bind(p,discovery=true,previousAccount) only treats an eth_accounts answer as an identity change when a previous wallet account was actually observed (auth.ts:282, 'only a proven account change owns cleanup'), so a restored session A plus a first-seen wallet account B shows 'mismatch' and sends nothing.

     The accountsChanged path has no such guard. accountChanged(a) computes other purely from the displayed session and the incoming account; with s.account===null (wallet locked at page load, eth_accounts answered []) the first account the wallet ever reports is treated as an A->B switch: gen++, session cleared, automaticCleanup('account-switch',...,held,true) sends POST /api/auth/logout {expectedAddress:A} (204), the server revokes A's live row, and 'signed-out' is broadcast to sibling tabs.

     Nothing changed: no account was ever established for this page. MetaMask-class wallets answer eth_accounts [] while locked and emit accountsChanged([selected]) on unlock, so a user who returns with a valid 7-day cookie and unlocks a wallet whose selected account differs from the session loses the session server-side, the same class of unintended revocation as Audit7 #1, reached through a different transport.

     Fix: in accountChanged, treat an incoming account with no previously observed account (this.s.account===null and no click/owner context) the way the discovery path does: set the account, show mismatch, and leave cleanup to a proven change or an explicit action.

     Fresh checkout, Node 24.19.0, source/: npm ci --ignore-scripts.

     Script using tests/auth-r7-fixtures.mjs (run with node): w=setup(); A,B=newAccount(); b=w.browser(); p=provider(null) /* eth_accounts -> [] /; b.signIn(A).verify.status===200; q=tab(w,b,p); await until(restored&&session); assert q.c.state.account===null; rows before {created:1,live:1,revoked:0}; p.switchTo(B) / accountsChanged([B]) */; await flush(40).

     MEASURED: logouts=[{address:true,nonce:false,status:204}], rows after {created:1,live:0,revoked:1}, state.session=null, state.account=B, cleanupPlans=[{reason:'account-switch',kind:'displayed-session'}], broadcast=['signed-out'], prompts 0, challenge 0, verify 0.

     CONTROL (same state, discovery path): getProvider:()=>chosen with chosen=null, then chosen=provider(B); q.notifyProvider('discovery'); await account===B.

     MEASURED: logouts=[], rows {created:1,live:1,revoked:0}, state.session=A (mismatch shown), plans=[], broadcast=[].

     Expected: both first observations behave like the control (session kept, no logout, no broadcast); actual: the unlock path revokes A's row.

   • lowOverlapping fresh=1 home cohort behind a slow NFT index read serialises into one budget charge, index read and proof epoch per waiter (Audit7 #2 partial)source/server/ownership.ts:266

     Fix 2 makes same-context waiters chain onto the pending ProofFlight and re-evaluate after it settles (ownership.ts:234-237). Each re-evaluation re-asks the candidates Cache with ttl=OWNERSHIP_TTL_MS (30 s) for fresh=1, measured against the entry's at, which Cache.get sets when the load STARTS (ownership.ts:202), and the discovery keep predicate compares d.indexed.at (the index-read start, line 268) against the live clock with the same 30 s bound (line 284).

     When budget admission + index read + proof take >= 30 s of live clock (the pinned CHAIN_TIMEOUT_MS is 10 s per page and NFT_PAGE_CAP is 5, so a 3-page read at the timeout already crosses it), the first waiter re-evaluates after the predecessor completes, finds the just-completed answer 'too old' for fresh, charges chain:index again and reads the index again, and the next waiter does the same after it.

     Every waiter also starts a new proof epoch at latest because the previous epoch is already past OWNERSHIP_TTL_MS. The cohort that fix 2 says shares 'one index read, one chain-index budget charge and one proof' instead costs N of each, serially, and the last waiter answers after N x (index time) (10 minutes measured for N=20).

     The amplification is bounded only by the per-location chain:index limiter (20/min), which such a cohort then exhausts for every other address at that location (their reads become 'limited'). Ordinary (300 s) cohorts are unaffected.

     Fix: let a waiter that joined while the predecessor's index read was in flight accept that read's completion as its cohort answer (date the fresh window from completion, or carry a 'satisfied by flight X' marker), instead of re-admitting against the start timestamp.

     Same fixture shape as tests/ownership-audit8.test.mjs advancingFixture (Ownership with offline gateway/chain fixtures, request.clock=()=>state.live, budget advances live by 30 ms, ownerOf advances 100 ms) but the index read advances the live clock by 30_000 ms (or 29_900 ms).

     20 overlapping ownership.home(A, request(START+i), fresh=true) with the first index read gated until all 20 have entered.

     MEASURED (index 30 s): budget=20, index=20, rpc=20, 20 distinct checkedAt epochs, all 20 views eligible=1/recheck none, live clock advanced 602,600 ms.

     MEASURED (index 29.9 s): budget=20, index=20, rpc=20.

     CONTROLS in the same script: 20 ordinary readers with the 30 s index read -> budget=1,index=1,rpc=1, 1 epoch, 30,130 ms; mixed 10 ordinary + 10 fresh with a 200 ms index read -> budget=1,index=1,rpc=1, 1 epoch.

     Expected per the fix statement: 1/1/1 for the fresh cohort as well; actual: 20/20/20.

   • lowOpt-in artifact store writes through a dangling symlink inside the scheduler namespace, escaping source/tmp (Audit7 #8 partial)source/tests/auth-artifacts.mjs:28

     file(name) only inspects an existing output path when existsSync(path) is true. existsSync follows symlinks, so a symlink whose target does not exist yet reports false, the lstat/isSymbolicLink check is skipped, and writeFileSync(path,...) then follows the link and CREATES the target outside source/tmp. The directory-level validate() walks only the components of the artifact directory, not the output file itself, so it does not catch this either.

     AUDIT8_REVIEW_RUNNER.md states that 'a symlink/junction escape, or a non-regular output file is rejected'; that holds for symlinks to existing files/directories but not for dangling ones, which is the natural state of a pre-planted link (the attacker's target file does not exist until the write). Impact is local-only (a reviewer machine with a hostile pre-planted link in an opt-in directory), hence low, but it directly contradicts the fix-8 guarantee.

     Fix: use lstatSync(path,{throwIfNoEntry:false}) (or fs.lstat in a try) and reject any existing lstat entry that is not a regular file, and open with O_NOFOLLOW/'wx' semantics (e.g. fs.openSync(path,'wx') after unlinking only a verified regular file).

     whole finding

     Node 24.19.0, fixture outside the tree: mkdir -p /tmp/fx/src/tmp/auth-reference-scheduler /tmp/fx/outside; symlinkSync('/tmp/fx/outside/escaped.json','/tmp/fx/src/tmp/auth-reference-scheduler/core500-RESULT.json') (target absent); store=createArtifactStore({sourceDir:'/tmp/fx/src',requestedDir:'tmp/auth-reference-scheduler'}); store.write('core500-RESULT.json',{status:'PASS',note:'escape'}).

     MEASURED: write threw: null; target exists before write: false; after write: true; /tmp/fx/outside/escaped.json contains {"status":"PASS","note":"escape"}; the namespace entry is still a symlink.

     Expected: throw 'artifact output is not a regular file' and write nothing outside source/tmp.

     CONTROL: a symlink to an EXISTING file or directory is rejected as documented (tests/auth-artifacts.test.mjs covers only the existing-directory case).

   • infosanitizeArtifact masks only /home, /Users, /tmp and drive-letter paths; other absolute machine paths pass through verbatimsource/tests/auth-artifacts.mjs:10

     The string sanitizer is the last line of defence for the fix-8 claim that persisted artifacts expose no private machine path. It is a prefix allow-list, not a path detector: checkouts under /root (Docker/CI default), /var/lib//workspace, /opt, /srv, /workspace, /data or /mnt// are not masked, and WSL paths such as /mnt/c/Users/... are only partially masked ('/mnt/c[local-path]').

     Today the only strings that reach the artifact files are oracle messages and failure.message/detail from the driver, which currently carry no absolute paths (my opt-in run: 22 files, 0 matches for /home/, /tmp/, drive letters, sourceRoot, runtimeExe or cwd), so this is informational: a future assertion message or a Node error text containing a file URL would leak under those roots.

     Fix: mask any absolute POSIX path segment that resolves inside the checkout (replace the realpath of sourceDir and its parents) rather than enumerating home-directory prefixes.

   • infoReview runner prerequisite accepts any node_modules/viem whose package.json version string matches; it does not verify the locked package bytessource/scripts/review-tests.mjs:25

     AUDIT8_REVIEW_RUNNER.md and TEST_RESULTS.json ('viemRealPackage': true) present npm run test:review -- --check as verification of 'the actual pinned viem package'. checkReviewPrerequisites only compares three version strings. A directory containing nothing but {"name":"viem","version":"2.56.9"} passes --check with the same REVIEW_PREREQUISITES line a genuine install prints.

     The product tests would then fail at import time, so a stub cannot fake a green run, but the --check receipt itself is not evidence of a real locked package, and the published TEAM claim rests on it.

     Informational: the independent reviewer's own npm ci --ignore-scripts (which verifies the lockfile's sha512 integrity) is what establishes the real package, as it did here.

     Fix: compare the installed package's _integrity/package.json dist.integrity or hash the installed tree against lock.packages['node_modules/viem'].integrity before printing the receipt.

     whole finding

     Copy package.json, package-lock.json and scripts/review-tests.mjs into an empty directory, create the 23 listed test paths as empty files, write node_modules/viem/package.json = {"name":"viem","version":"2.56.9"} and nothing else, then run node scripts/review-tests.mjs --check.

     MEASURED: prints REVIEW_PREREQUISITES {"node":"v24.19.0","viem":"2.56.9","testFiles":23} and exits 0, identical to the genuine checkout's receipt.

     Expected: a mismatch/missing-integrity error.

   • infoPolicy decision to confirm: an unreconciled lock-reconcile verify owner is revoked by page teardown ('stop'), so a committed same-account session is lost when a lock coincides with a failed session resource/src/world/authCleanup.ts:23

     Fix 3 keeps a lock from revoking a committed verify (planCleanup('lock') -> 'reconcile'; AUDIT8_CLOSURE.md 'Lock is not logout').

     But cancelOwners('stop') in the teardown overwrites the owner's cancellationReason from 'lock-reconcile' to 'stop' (authLifecycle.ts abandon() re-sets the reason on an already-abandoned RETAINED owner), and planCleanup('stop') then selects 'verify-owner', so revokeAbandoned sends POST /api/auth/logout {expectedNonce} and the server revokes the session this very flow committed.

     The revocation is correctly scoped (same lifetime, nonce-conditional, no cross-revocation of another row was observed) and fail-safe, so this is not a security defect; it is a product/policy outcome the closure documents do not state: a user whose wallet auto-locks during verify while /api/auth/session is 503 and who then navigates away must sign again next visit even though their verify succeeded.

     Listed so the requester can record it as accepted policy or decide that an unreconciled lock owner should be left for the next life's canonical read (LOW-4 restart path) rather than revoked.

     whole finding

     tests/auth-r7-fixtures.mjs: provider(A); hold POST /api/auth/verify in beforeSend; after it is dispatched, p.switchTo(null) (lock), make GET /api/auth/session answer 503, release the verify (200, cookie set).

     Wait until lifecycleSnapshot.cleanup.status==='RETAINED' && cancellationReason==='lock-reconcile'.

     MEASURED before stop: rows {created:1,live:1,revoked:0}, logouts 0.

     Then q.stop() (page teardown) and flush.

   Reviewed public commit: 88c130283efc45260f9e00da8d2d3055c38483bd, compared with 7215c5d89a96bc79113a85766c04868d54393f3c.

   Finding	Severity / disposition	Concrete failure	Closure consequence
   F1 — Ownership proof expires during final D1 read	Low · open — ownership.ts:337–352	A home request reuses a proof aged 29,999 ms. A 1 ms sighting-query delay crosses expiry; the response still grants eligibility for a transferred seat.	SOURCE-CLOSURE blocker: expired ownership evidence grants owner status. This additional defect existed in the previous source too.
   F2 — Dangling symlink bypasses artifact containment	Info · partial closure of prior #8 — auth-artifacts.mjs:28–32	An accepted output filename is a symlink whose target does not yet exist. existsSync returns false, bypassing lstat; writing follows the link outside the allowed tmp directory.	Prevents declaring all eight findings closed. Local opt-in artifact issue; no demonstrated wallet or Worker compromise.

   Reproductions

   F1 uses the actual Worker, migrated SQLite and supplied offline chain fixtures:

   1. Authenticate A and prove seat 7 at time T.
   2. At T+29,999, request home again.
   3. During the final seat_presence query, transfer the fixture seat to B and advance the clock by 1 ms.
   4. Observe HTTP 200, eligible=1, original checkedAt=T, and client status owner.

   Query delay	Proof age at response	Actual eligibility	Expected
   0 ms	29,999 ms	1	Valid cached result
   1 ms	30,000 ms	1	Unavailable or fresh proof yielding 0
   2 ms	30,001 ms	1	Unavailable or fresh proof yielding 0

   The next request reproves at latest and returns eligibility 0. Before that recovery, each run has session rows created/live/revoked = 1/1/0, challenge rows total/used/pending/invalidated = 1/1/0/0, and index/budget/proof-RPC = 1/1/1. Setup makes one challenge, one verify and one eth_getCode; UI prompts, cleanup and hints are zero.

   The completion guard in proof() executes before the later D1 await. Recheck the live clock after all home enrichment and lane work; expired evidence must be reproved or rejected.

   F2 safely creates a synthetic source root S inside the checkout’s explicit source/tmp, then:

   S/tmp/store/core500-RESULT.json -> ../../escaped.json
   

   With S/escaped.json absent, write() returns true and creates it outside S/tmp. The identical link is rejected on a second write, after its target exists. All Auth/index/budget/RPC counts are zero. The fixture was removed afterward.

   Both reproduction commands exited 0, asserting the observed defects. Exact executable code is embedded in the JSON. Reproduction SHA-256 values, including terminal newline:

   • lowHome response can grant ownership after its 30-second proof expires during D1 sightingssource/server/ownership.ts:337

     OPEN; SOURCE-CLOSURE blocker: stale ownership authority violates the fixed checkedAt epoch, despite Low impact (household/owner UI; no asset transfer). On public 88c130283efc45260f9e00da8d2d3055c38483bd, proof() validates completion freshness at lines 307-308, but home() then awaits D1 sightings at line 337 (and can await lane work at 347-349) without rechecking at the final response.

     With a valid session A and an ownerOf(A,7) proof at T, a second home request at T+29999 reuses that proof; only 1 ms of sighting-query latency, with seat 7 transferring to B during the wait, takes completion to T+30000, lines 350-352 still return HTTP 200 eligible=1 and checkedAt=T. AuthClient accepts this response at source/src/world/auth.ts:357-361; statusOf returns owner.

     This is a boundary x invariant gap after the repaired proof-completion guard, not the accepted stale cache interval before expiry.

     Minimal fix: check the live Worker clock against proof.checkedAt after all awaited home enrichment/lane work, and either obtain a new latest-block proof with new checkedAt or return OWNERSHIP_UNAVAILABLE; never return the expired fallback on lane failure. Recheck ranking/status time as appropriate.

     Related prior comparison: https://github.com/Identity-md/research/blob/main/jobs/4e150a3c-3ee4-4856-972e-db5db4f4d3fc/files/AUDIT.md (captured SHA256 93ddeba22bd0dbcbff5a83f65bc48e9a373c7c2b8c3f6a848920a5fc7fa939a0), findings 2/5; this final-sightings path is an additional issue, not evidence that their exact repair probes still fail. Reviewer offline measurement; no live D1 claim.

     Public previous-source comparison shows the final home/sightings path was already present at 7215c5d89a96bc79113a85766c04868d54393f3c; this is an additional pre-existing scoped defect, not a claim that Submission8 introduced it.

     Fresh pinned checkout; Node v24.21.0 and locked real viem 2.56.9 installed with npm ci --ignore-scripts. Run the following from source/ with node --input-type=module via stdin. It uses the actual Worker, migrated SQLite and supplied local upstream fixtures, changes no production files, and asserts the observed defect; exit 0. Event order: one fixture sign-in commits A; initial home proves seat 7 at T; at T+29999 another home call reuses this proof; its post-proof seat_presence query advances injected time by 0/1/2 ms and transfers the fixture seat to B; home completes. Actual HTTP 200, eligible=1, owner state and original checkedAt=T at ages 29999/30000/30001. Age 29999 is the valid baseline. Expected at >=30000: unavailable or latest reproof yielding zero. Subsequent request at >=30000 yields eligible=0 with total proof RPC=2, proving the stale response is not a fixture's permanent ownership claim. A separate cold-proof control held sightings for 29999/30000/30001 ms and reproduced the same expiry boundary.

   • infoDangling output symlink bypasses opt-in scheduler artifact containmentsource/tests/auth-artifacts.mjs:28

     PARTIAL closure of prior Info #8 (https://github.com/Identity-md/research/blob/main/jobs/4e150a3c-3ee4-4856-972e-db5db4f4d3fc/files/AUDIT.md, captured SHA256 93ddeba22bd0dbcbff5a83f65bc48e9a373c7c2b8c3f6a848920a5fc7fa939a0).

     The default-disabled behavior and existing-link controls pass, but the explicit opt-in requirement to reject symlink/nonregular output is not satisfied. existsSync follows a symbolic link and returns false when its target is missing, so file() skips lstat on that existing directory entry. writeFileSync at line 32 follows the link and creates the missing target, which can be outside the validated artifact directory or source/tmp if writable.

     A preexisting dangling core500-RESULT.json link therefore defeats containment without a race.

     Severity Info: local opt-in artifact hygiene, not wallet/Worker authority; it prevents declaring all eight findings fully fixed.

     Minimal fix: lstat the output path independently of target existence (treat only ENOENT for the directory entry as absent), reject symbolic links/nonregular entries, and open with an appropriate no-follow/exclusive/atomic strategy. Inspect existing directory components without following dangling links as well. Reviewer reproduction used only source/tmp and removed its fixture.

     whole finding

     From source/ on Node v24.21.0, run the following with node --input-type=module via stdin; exit 0. Create a synthetic source root S inside the real checkout's explicit source/tmp/reviewer-artifact-probe and request tmp/store under S. Precreate S/tmp/store/core500-RESULT.json as a relative symlink to ../../escaped.json with that target absent. Expected: reject the symlink and create no target. Actual: write returns true, creates S/escaped.json outside the allowed S/tmp, and leaves the output as a symlink; serialized trace actions retain their original meaning. Control: a second write through the identical link is rejected once its target exists. No session/challenge rows; prompt/challenge/verify/cleanup/hint/index/budget/RPC counts all zero. This safe fixture keeps all physical writes inside the real source/tmp and removes them in finally.

   All three snippets match their cited lines, the findings file parses, and the repository tree is unchanged apart from the ignored findings file and the ignored dependency install. Nothing further is needed; here is the review.

   Verdicts and findings

   SOURCE-CLOSURE: none of my findings blocks closure. All eight Audit7 rows are closed at the pinned candidate, three of them with a documented policy residual that the requester should confirm rather than a defect that reopens the row. RELEASE-READINESS: unknown. Every production fact in Submission8/BUILD_DEPLOYMENT.json is a TEAM readback that I did not and may not re-measure (no live requests were made), the canonical deploy invocation exited 1 on a Windows EPERM after Wrangler exited 0, and the public snapshot cannot build the full frontend. That is a release gate, not a source defect.

   #	Severity	Location	Finding	State	Blocker
   1	Low	source/server/ownership.ts:308	A delta ownerOf proof on a still-valid epoch that completes at or after the 30 s deadline is thrown away as 503 OWNERSHIP_UNAVAILABLE. The keyed RPC is spent and discarded, and all same-context waiters inherit the 503.

   2	Info	source/src/world/auth.ts:306	An initial wallet pick while no provider is in use (two wallets announced, needsChoice) is handled as a provider switch and revokes the cookie-restored session via POST /api/auth/logout {expectedAddress} before the picked wallet's account is read, even when it holds the session's own account. Residual of prior Low #1, now requiring an explicit pick.	policy decision	no
   3	Info	source/tests/auth-artifacts.mjs:10	The artifact string sanitizer masks only drive-letter paths and /home/, /Users/, /tmp/ roots.

The primary mechanism (hidden keys, zero default artifacts, source/tmp confinement) holds.	partial	no

   Closure matrix dispositions, in my judgement: rows 1, 2, 3, 4, 5, 6, 7, 8 are fixed. Row 1 carries finding 2 as an explicit-pick residual. Row 3 carries a documented residual: a lock followed by a 503 reconciliation and then a page teardown revokes the committed session through the owner's nonce, per AUTH_STATE_MACHINE.md row 32 (I measured it: rows live 1 → 0, one logout with nonceAssertion:true, 204). Row 5 carries finding 1. Row 6 and 7 accept up to 60 s of future stamp by the stated policy, so a Worker clock more than 60 s ahead still produces the failure ladder, and a warmed copy dated in the future gets its TTL from the producer stamp. Row 8 carries finding 3.

   • lowDelta ownerOf proof that completes at/after its epoch deadline is discarded as 503 instead of re-proving at latest; one keyed RPC wasted and every same-context waiter failssource/server/ownership.ts:308

     State: policy decision / accepted limit to confirm (OWNERSHIP_FRESHNESS.md line 9 says a delta finishing at/after its deadline is unavailable), not a SOURCE-CLOSURE blocker.

     Blocker: no (fails closed: no ownership granted, no authority change, RPC bounded by chain:index/home limiters).

     Mechanism: Ownership.proof() re-evaluates the epoch at proofNow (line 289-291); when the old epoch is still valid it issues a delta ownersOf() pinned to the old block for newly discovered ids (line 298), then re-reads the clock (line 307) and throws OwnershipUnavailable when done - checkedAt >= 30000 ms (line 308). The completed, valid pinned-block result is discarded, nothing is stored, and the request answers 503 OWNERSHIP_UNAVAILABLE.

     Because the failure propagates through the ProofFlight promise, every overlapping same-context caller queued behind it (line 234-237) receives the same 503. The very next request creates a fresh epoch at latest and succeeds, so the request could have re-proved at latest itself (the documented rule for discovery waits crossing the deadline, OWNERSHIP_FRESHNESS.md line 16) instead of answering 503.

     Window: any request carrying a new candidate (roster or fresh=1 index) that starts its delta within the last RPC-latency of a 30 s epoch.

     Counts (my reproduction, direct Ownership class, offline fixture, live clock advanced 30 ms per budget / 200 ms per index read / 100 ms per eth_call): ordinary variant: epoch at T0; request at T0+29.9 s with roster seat 8 added: result OWNERSHIP_UNAVAILABLE, eth_call tags ['latest','0x1406f40'], rpc 2, index 1, budget 1; retry: eligible 2, rpc 3 (tags add 'latest'). Control at T0+29.8 s: eligible 2 at the old checkedAt, rpc 2.

     Cohort: 20 overlapping identical requests at T0+29.9 s: 20 errors / 0 ok / rpc 2. fresh=1 variant: epoch 2 created from the 5-minute candidate cache; Check again (fresh=1) at epoch+29.7 s whose index read names newly bought seat 8: result OWNERSHIP_UNAVAILABLE with index 2, budget 2, rpc 3 (chain:index budget and the delta eth_call both spent); fresh=1 retry: eligible 2, rpc 4.

     Expected: the request whose delta crossed the deadline starts a new latest proof (new checkedAt) or at minimum keeps the valid old epoch's seats as 'limited' rather than 503; one RPC should not be spent and discarded.

     Separation: reproduced facts above are my own offline measurements; the policy sentence is a TEAM document; production frequency unmeasured (no live requests made). Minimal fix preserving the design: when valid && delta completes with done past the deadline, fall through to a fresh latest proof in the same request (checkedAt=done-side clock) rather than throwing; keep the throw for the first/expired-epoch case.

     whole finding

     Offline, no network.

     From a fresh checkout with Node 24.19.0: cd source && npm ci --ignore-scripts; create /tmp/probes/ownership-deadline.mjs (symlink source/node_modules into /tmp/probes) importing Ownership from /server/ownership.ts with the advancingFixture pattern of tests/ownership-audit8.test.mjs (roster ['7'], indexIds ['7'], ownerById {7:A,8:A}; clock +30 ms per budget, +200 ms per index read, +100 ms per eth_call; request.clock=()=>state.live).

     Steps: (1) home(A,req(START),false) -> eligible 1, checkedAt=START+230, rpc 1.

     (2) state.live=checkedAt+30000-100; state.roster=['7','8']; home(A,req(state.live),false).

     Expected: eligible 2 (new latest epoch or served pinned delta).

     Actual: rejects OWNERSHIP_UNAVAILABLE; state.rpc=2 with tags ['latest','0x1406f40'] (the delta eth_call was sent and its answer discarded).

     (3) same call again: eligible 2, checkedAt=START+30230, rpc 3.

     Cohort: 20 x home(A,req(state.live),false) launched together at step (2): 20 rejections, 0 views, rpc 2. fresh=1 path: after step (1) set state.live=START+250000, home(...,false) -> new epoch checkedAt=START+250000 (rpc 2, index still 1); state.live=250000+29700; state.indexIds=['7','8']; home(A,req(state.live),true).

     Expected: eligible 2.

     Actual: OWNERSHIP_UNAVAILABLE with index 2 / budget 2 / rpc 3; retry fresh=1 -> eligible 2, rpc 4.

     Control: step (2) at checkedAt+29800 instead of +29900 -> eligible 2 at the original checkedAt, rpc 2 (the Audit5 'later same-roster request after the pending epoch deadline' test expects the 503 for a first/expired epoch; this case is a valid epoch whose 100 ms delta crosses the boundary).

   • infoAn initial wallet pick from the no-provider state (two wallets announced, none in use) is treated as a provider switch and revokes the cookie-restored session even when the picked wallet holds the sessource/src/world/auth.ts:306

     State: policy decision to confirm (AUDIT8_CLOSURE.md: 'Selecting another wallet explicitly keeps the intended cleanup'); blocker: no (no cross-account authority, no privilege gain; the user's own restored session is revoked and one extra signature is required). This is the residual of prior Low #1 (unintended session revocation class), now reduced to an explicit pick.

     Mechanism: providerChanged('selection') (line 293) only returns early when p===this.bound (line 294); when the page has used no provider yet (WalletRegistry.current() is null because needsChoice: wallet.ts line 86-88, two announcements and no remembered rdns), this.bound is null, so the first pick runs line 304-306: gen++, cancelOwners('context-switch'), sessionKnown=false, automaticCleanup('provider-switch',...,held). planCleanup (authCleanup.ts line 22) returns displayed-session for the restored session, so POST /api/auth/logout {expectedAddress:} is sent with the live cookie before the picked provider's eth_accounts is read, and the Worker revokes the row (204, Set-Cookie clears).

     Nothing compares the picked wallet's account with the session address; the previous wallet context that a 'switch' would replace does not exist.

     Event order (my reproduction, real AuthClient + real Worker + node:sqlite via tests/auth-r7-fixtures.mjs and WalletRegistry): announce wallet one (account A) and wallet two (account B) -> needsChoice true, current() null -> browser signs in as A (direct challenge/verify, 200) -> AuthClient.start(): GET /api/auth/session PRESENT(A), account null, rows created 1 / live 1 / revoked 0 -> registry.choose(options[0]) (the wallet holding A) -> cleanupPlans [{eventId:1,reason:'provider-switch',kind:'displayed-session'}] -> POST /api/auth/logout addressAssertion true, nonceAssertion false, 204 -> rows created 1 / live 0 / revoked 1; client session null, ended 'revoked', account A, notice null; GET /api/auth/session signedIn false.

     Counts: prompts 0, challenges 0, verifies 0, cleanups 1, hints 0, RPC 0. Expected under the closure wording 'passive provider discovery must preserve cookie-restored session ... explicit selection remains a genuine context change': debatable for a pick that replaces no bound provider; a conservative alternative is to treat a pick from bound===null like discovery (bind, read eth_accounts, and only an account other than the session's is a switch).

     Realistic triggers are narrow: the remembered wallet is not announcing while another is, two extensions claim the same rdns, or localStorage was cleared while the cookie survived.

     Separation: reproduced fact above (offline fixtures); real extension/browser behaviour unmeasured.

     whole finding

     Offline. cd source && npm ci --ignore-scripts; probe (Node 24) importing WalletRegistry from /src/world/wallet.ts and {setup,newAccount,provider,tab,until,flush,rows,logouts,routeEvents} from /tests/auth-r7-fixtures.mjs: const w=setup(),A=newAccount(),b=w.browser(),first=provider(A),second=provider(newAccount()); const reg=new WalletRegistry({ethereum:null,addEventListener,removeEventListener,dispatchEvent:()=>true},null); reg.start(); announce first as rdns io.example.one and second as io.example.two (reg.state.needsChoice===true, reg.current()===null); await b.signIn(A) (verify 200); const q=tab(w,b,first,{getProvider:()=>reg.current()}); reg.subscribeProvider(reason=>q.notifyProvider(reason)); await until(()=>q.c.state.restored&&q.c.state.session); // PRESENT(A), account null, rows live 1. reg.choose(reg.state.options[0]); await flush(30).

     Expected: session for A preserved (no logout; account A becomes connected to its own session).

     Actual: logouts(q) = [{addressAssertion:true,nonceAssertion:false,status:204}], rows {created:1,live:0,revoked:1}, q.c.state.session null, ended 'revoked', GET /api/auth/session signedIn:false, prompts 0.

   • infoArtifact path sanitizer only masks Windows drive paths and /home, /Users, /tmp roots; checkout paths under /srv, /opt, /var, /root, /workspace, /Volumes or /dev/shm pass through unmaskedsource/tests/auth-artifacts.mjs:10

     State: partial (defense-in-depth gap in the Fix 8 'sanitizes paths' claim); blocker: no. The primary mechanism of Fix 8 holds in my run: the default review command persisted zero artifacts and created no sibling evidence directory, hiddenKeys removes sourceRoot/runtimeExe/runtimeExecutable/executable/cwd, and opt-in output is confined to source/tmp with symlink/junction and non-regular-file rejection.

     The secondary string sanitizer, however, recognises only drive-letter paths and POSIX paths beginning /Users/, /home/ or /tmp/.

     A reviewer or CI checkout under any other root (common: /srv, /opt, /var/lib/, /root, /workspace, /Volumes on macOS, /dev/shm, /mnt/ for WSL where only the trailing /Users/... part is masked) leaves a machine path in any artifact string that happens to carry one (an error message such as Node's ERR_MODULE_NOT_FOUND 'Cannot find module ' or an ENOENT text written into failure.message/detail by the replay CLI's sanitizeArtifact({status:'FAIL',message:error.message,...}) in scripts/replay-auth-trace.mjs line 11).

     The unit test auth-artifacts.test.mjs line 14 only exercises C:\ and /home/ inputs, and its !first.includes(root) assertion is satisfied by hiddenKeys regardless of the regex.

     Concrete inputs and actual outputs from sanitizeArtifact({message:'Cannot find module '+p}): '/home/ci/imd/source/src/world/auth.ts' -> 'Cannot find module [local-path]' (masked); 'C:\ci\imd\source\tests\x.mjs' -> masked; '/srv/ci/imd/source/src/world/auth.ts' -> unchanged; '/opt/build/imd/source/tests/auth-r8.test.mjs' -> unchanged; '/var/lib/jenkins/workspace/imd/source' -> unchanged; '/root/imd/source' -> unchanged; '/workspace/imd/source/tests' -> unchanged; '/Volumes/Work/imd/source' -> unchanged; '/dev/shm/imd/source' -> unchanged; '/mnt/c/Users/dev/imd/source' -> '/mnt/c[local-path]' (prefix leaks).

     Minimal fix: mask by the artifact store's own realpath(sourceDir) (and os.tmpdir()/homedir()) rather than a fixed root list, or mask any absolute POSIX path segment that resolves inside the checkout.

     whole finding

     Offline. cd source && npm ci --ignore-scripts; node --input-type=module -e "const {sanitizeArtifact}=await import('./tests/auth-artifacts.mjs');for(const p of ['/home/ci/imd/source/src/world/auth.ts','/srv/ci/imd/source/src/world/auth.ts','/opt/build/imd/source/tests/auth-r8.test.mjs','/var/lib/jenkins/workspace/imd/source','/root/imd/source','/workspace/imd/source/tests','/Volumes/Work/imd/source','/dev/shm/imd/source','/mnt/c/Users/dev/imd/source'])console.log(JSON.stringify(sanitizeArtifact({message:'Cannot find module '+p})))".

     Expected: every message reads 'Cannot find module [local-path]'.

     Actual (Node 24.19.0): only the /home/... input is fully masked; /srv, /opt, /var, /root, /workspace, /Volumes and /dev/shm inputs are returned unchanged, and /mnt/c/Users/... becomes '/mnt/c[local-path]'.

   IMD Ember World, eighth Swarm audit: Audit7 closure review of public 88c130283efc45260f9e00da8d2d3055c38483bd

   Verdicts. SOURCE-CLOSURE: seven of the eight Audit7 rows are closed in the pinned source; row 6 (clock skew) is partial. Nothing I measured blocks closure: no wrong Auth or ownership authority, no unintended prompt or session, no old-flow cross-revocation, no unbounded keyed RPC, no new wallet method, route or header. RELEASE-READINESS: unknown. Every production fact (deployed Worker bytes, bindings, migrations, WAF, D1 behaviour) is a TEAM readback I could not measure, the full frontend cannot be built from the public tree, and the regression files for wallet.ts, ownership.ts and worker/app.ts do not load publicly.

   Findings are written to .imd-findings.json (one Low, one Info). Everything below separates reviewer facts (my runs), TEAM/inherited records, inference and unavailable checks.

   • lowAudit7 #6 partial: a browser clock more than 60 s behind the Worker stamp still turns every good snapshot into a failed read (permanent 120 s retry ladder) and hides fresh market/floor datasource/src/world/cadence.ts:62

     Fix 6 replaced the zero-tolerance comparison with isFreshPublicRemote, whose lower bound is PUBLIC_REMOTE_SKEW_MS = 60000 (source/src/shared/freshness.ts:16). That bound was taken from the gateway's inter-Worker shared-copy policy, but here the clock being compared is the browser's device clock against a Worker-produced epoch.

     The project's own device-clock assumption is SIWE_CLOCK_SKEW_MS = 10 min (source/src/world/siwe.ts:9): a device 2 minutes slow can sign in, yet worldReadResult classifies each server-labelled 'fresh' snapshot as false, so startPoll runs the failure ladder 30 s / 60 s / 120 s forever (30 reads per hour instead of 4) and poll.failures climbs without bound. marketView (source/src/world/market.ts:117) applies the same bound, so the same device sees market state 'stale', weather 'unknown' and the floor card hidden although the Worker answered fresh data.

     This is the same failure mode as prior finding #6 with a narrower trigger (lag > 60.000 s instead of > 0 s); it is not an authority issue and does not block source closure.

     Suggested minimal fix: for public display/polling classify by the server's state and treat a negative age as 0 (or use a bound at least as large as SIWE_CLOCK_SKEW_MS); keep the strict helper for sessions/ownership/local caches unchanged.

     whole finding

     Node 24, in source/: node --input-type=module -e "import {worldReadResult,startPoll} from './src/world/cadence.ts';import {marketView} from './src/world/market.ts';const s=at=>({state:'fresh',data:{priceUsd:8,change24h:12},url:'x',fetchedAt:at});let clock=2_000_000,p;const env={set:(fn,ms)=>{p={fn,ms};return p;},clear:()=>{},hidden:()=>false,now:()=>clock,onVisible:()=>()=>{}};for(const behind of [60_000,60_001,120_000]){const poll=startPoll(async()=>worldReadResult({swarm:s(clock+behind),workers:s(clock+behind)},clock),env);await new Promise(r=>setTimeout(r,0));const sched=[];for(let i=0;i<5;i++){sched.push(p.ms);clock+=p.ms;await p.fn();await new Promise(r=>setTimeout(r,0));}poll.stop();console.log(behind,sched,poll.failures,marketView(s(clock+behind),clock).state,marketView(s(clock+behind),clock).weather);}" .

     Measured: 60000 -> [900000 x5], failures 0, fresh/brilliant (expected).

     60001 -> [30000,60000,120000,120000,120000], failures 6, stale/unknown.

     120000 -> same ladder, stale/unknown.

     Expected for a device merely slow by 1-10 minutes (within the project's SIWE device-clock allowance): 900000 ms cadence, failures 0, market fresh.

   • infoPolicy decision to confirm: the first explicit wallet pick, when no wallet was yet in use, revokes a cookie-restored session even when the picked wallet holds that same addresssource/src/world/auth.ts:306

     providerChanged('selection') treats every explicit pick as a context switch and plans 'displayed-session' cleanup whenever a session is displayed, including when this.bound was null (no provider had been used by the page).

     With two EIP-6963 wallets installed and no remembered choice, WalletRegistry.current() returns null, the page restores the session from the cookie and shows the chooser; the user's first pick of the wallet that holds the session's own address then sends POST /api/auth/logout {expectedAddress} and the live session row is revoked (server /api/auth/session answers signedIn:false).

     There was no account or provider to switch away from, no prompt, and the picked account equals the session address, so a user who merely answered 'which wallet' loses a valid session and must sign again.

     This is documented ('an explicit wallet pick remains a context switch, even for the same address') and pre-dates Submission8, so it is not a regression of the eighth candidate and not a closure blocker; it is reported so the owner can decide whether a first selection with no prior page-used provider should be exempt (e.g. treat selection with bound===null as discovery/bind only).

     whole finding

     Node 24, in source/, script importing tests/auth-r7-fixtures.mjs and src/world/wallet.ts: create a WalletRegistry with win.ethereum=null, announce two providers (rdns io.example.one holding account A, io.example.two holding B) before Auth start; browser b signs in as A via the real Worker (verify 200, sessions live=1); create the AuthClient tab with provider:()=>registry.current() and onProviderChange:registry.subscribeProvider; await restored session.

     Observed: current()===null, needsChoice=true, state.session=A, state.account=null.

     Then registry.choose(options[0]) (the wallet holding A).

     Observed after 40 ticks: one POST /api/auth/logout with expectedAddress (204), cleanupPlans=[provider-switch:displayed-session], sessions created 1 / live 0 / revoked 1, client session null, account A, prompts 0, GET /api/auth/session -> signedIn:false.

     Expected (if the first pick is not a switch): zero logouts, live 1, session A retained, account A.

   F2	Low	auth.ts:583	Audit7 #1 partial; source blocker. A locked provider’s first accountsChanged([B]) revokes cookie-restored session A despite no previously observed wallet account. Passive discovery of the same B preserves A.
   F3	Low	ownership.ts:266	Audit7 #2 partial. A slow, overlapping fresh=1 cohort repeatedly admits index reads and proofs. Twenty callers produced twenty discovery cycles and twenty proof epochs. This blocks the required cohort-sharing closure claim; it does not establish an unbounded RPC bypass.

   F5	Info	auth-artifacts.mjs:10	Audit7 #8 partial. Absolute paths under /root, /var/lib, /srv, /opt and other roots persist unmasked in artifact strings. Concrete sanitizer failure; no naturally occurring private-path disclosure was observed in the scheduler run.

   F1 needs a final freshness check after awaited enrichment and lane work. F2 needs to distinguish first account observation from an established account switch. F3 needs completed-flight reuse for existing waiters while preserving original timestamps and proof deadlines.

   • lowHome returns owner authority after the proof expires during post-proof D1 worksource/server/ownership.ts:337

     OPEN; SOURCE-CLOSURE blocker despite Low severity: household/owner UI accepts expired ownership evidence (no asset transfer demonstrated). On pinned public 88c130283efc45260f9e00da8d2d3055c38483bd, proof() checks freshness at 307-308, then home() awaits sightings (337), and potentially lane work (347-349), without validating proof.checkedAt again before returning at 350-352. AuthClient/statusOf accepts the resulting home as owner.

     A session-A home at checkedAt+29999 ms reuses seat-7 proof; 1 ms of sightings latency crossing the strict deadline suffices to return eligible=1 at age 30000 after the fixture owner transfers to B. Related prior Audit7 #2/#5: https://github.com/Identity-md/research/blob/main/jobs/4e150a3c-3ee4-4856-972e-db5db4f4d3fc/files/AUDIT.md (captured SHA256 93ddeba22bd0dbcbff5a83f65bc48e9a373c7c2b8c3f6a848920a5fc7fa939a0, independently matched).

     This is an additional scoped path, not a failure of the exact supplied repair test. Recheck the live clock after all awaited enrichment/lane work, and reprove at latest or fail unavailable on expiry/rollback; do not return an expired fallback. This is an offline reviewer measurement, not live D1 evidence.

     The complete home() body was also byte-compared with the previous public 7215c5d89a96bc79113a85766c04868d54393f3c via its raw public source and is unchanged: this is pre-existing scoped behavior, not an asserted Submission8-introduced regression.

     PARTIAL Audit7 #1; SOURCE-CLOSURE blocker for unintended session revocation. Passive bind/discovery at lines 280-285 correctly requires a previously observed wallet account before cleanup. accountChanged instead compares the first observed account only against the displayed cookie session.

     With a restored session A, initially locked provider eth_accounts=[], no click and no retained owner, accountsChanged([B]) is treated as an A-to-B switch even though the page never observed account A. Lines 593-597 select displayed-session cleanup: POST /api/auth/logout with expectedAddress A revokes the live row and broadcasts signed-out. The same first account B observed by passive discovery preserves A and shows mismatch.

     Require an established prior account or active flow context before classifying first unlock as an account switch; preserve cleanup for a proven A-to-B change. Pinned public 88c130283efc45260f9e00da8d2d3055c38483bd.

     Node v24.21.0 and genuine locked viem 2.56.9 installed via npm ci --ignore-scripts. Run below from source/ with node --input-type=module on stdin (exit 0 asserting defective behavior). unlock-first: session created/live/revoked goes 1/1/0 -> 1/0/1, challenge total/used/pending/invalidated remains 1/1/0/0, one address-conditional logout 204, zero nonce cleanup, plan account-switch:displayed-session, one signed-out broadcast. No post-setup prompts/challenge/verify; setup challenge/verify=1/1. Discovery-first control preserves 1/1/0, no cleanup or broadcast. Observed-switch control first binds A then emits B and correctly revokes once. Default empty-world fixture needs no ownerOf proof (no seat candidates). Expected first-unlock behavior matches discovery-first, while genuine observed switch remains fenced. Additional measured upstream counts: one index fetch before the event, no RPC methods, unchanged after the event. Thus the event adds zero index/budget/proof RPC work; emitted hint/broadcast count is one for unlock-first and observed-switch, zero for discovery-first.

   • lowSlow paginated fresh home cohort serializes into repeated index admissions and proof epochssource/server/ownership.ts:266

     PARTIAL Audit7 #2; blocks an all-eight-fixed SOURCE-CLOSURE verdict under the specified overlapping fresh=1 cohort requirement. Successful waiters recurse at 234-237. Candidate cache entry at 202 and index at 268 are dated before completion; the fresh keep predicate at 284 rejects the just-completed index when discovery plus proof consumes >=30000 ms.

     Twenty already-overlapping same-address fresh requests then each admit a new index cycle and start a new proof epoch. This is achievable within configured timeouts: four 7500-ms pages each below CHAIN_TIMEOUT_MS=10000, within NFT_PAGE_CAP=5, total 30000 ms; no single 30-second network fetch is needed. Measured 20 index cycles, 80 page fetches, 20 chain:index charges, 20 owner-proof RPCs and 20 checkedAt epochs, 602600 ms injected elapsed.

     It is bounded by existing request/admission controls; this does NOT demonstrate an unbounded/global RPC bypass or exhaustion of the 20-per-minute limiter (the measured slow cohort spans minutes). Preserve index producer age and strict proof TTL, while recognizing the completed discovery flight as satisfying waiters that joined that cohort, instead of recursively re-admitting them solely because its start timestamp aged.

   • infoDangling scheduler output symlink bypasses source/tmp containmentsource/tests/auth-artifacts.mjs:28

     PARTIAL Audit7 #8. existsSync follows the link and returns false when its target is absent, so file() does not lstat the existing symlink entry. writeFileSync at 32 then follows it and creates the target outside the permitted source/tmp. Directory validation does not inspect this final component. A deterministic preplanted dangling core500-RESULT.json symlink defeats the documented output containment without any race.

     Default-disabled output still works; no remote wallet/Worker authority is affected. Info severity reflects local opt-in artifact hygiene and a preexisting hostile filesystem entry. It prevents declaring the artifact-containment requirement fully closed.

     Use lstat independently of target existence and a no-follow/exclusive safe open strategy, checking directory components too.

     Node v24.21.0, pinned clean checkout. Run the script below from source/ with node --input-type=module stdin (exit 0). It creates a synthetic source S under the real source/tmp/reviewer-artifact-probe, links S/tmp/store/core500-RESULT.json to ../../escaped.json while the target is absent, and invokes createArtifactStore({sourceDir:S,requestedDir:'tmp/store'}).write(...). Expected: reject nonregular output and create nothing outside S/tmp. Actual: wrote=true, S/escaped.json created outside allowed S/tmp, output remains symlink, JSON trace unchanged. Control: second write through the same link is rejected once its target exists. All physical writes remain in the real source/tmp and are removed in finally. No session/challenge rows or prompt/challenge/verify/cleanup/hint/index/budget/RPC activity.

   • infoArtifact sanitizer leaves absolute machine paths under common POSIX roots unmaskedsource/tests/auth-artifacts.mjs:10

     PARTIAL Audit7 #8, separate mechanism from symlink containment. The string sanitizer enumerates only Windows drive prefixes and /Users/, /home/, /tmp/. Error/detail strings containing /root, /var/lib, /srv, /opt, /workspace, /Volumes or /dev/shm paths persist verbatim through createArtifactStore.write.

     WSL /mnt/c/Users/... is only partly removed. Hidden-key deletion works but does not cover arbitrary failure.message/detail strings.

     Info: a concrete sanitizer/output-contract failure and defense-in-depth gap; no current production secret leak or naturally emitted private-path failure is claimed. Default scheduler output remains disabled. Mask the actual checkout/machine roots or recognize absolute filesystem path tokens without altering replay action values.

     Non-authority issue; prevents the absolute no-private-path guarantee but not independently a remote release exploit.
