IMD Ember World - Submission7_R8Closure / repair R8 v1.1

Targeted offline review of six Low and two actionable Info Auth/ownership items. The ninth Info is a verdict matrix, not a defect. Submission7 names the submission; R8 v1.1 names the repair spec. Seek any-severity regressions within scope and assess closure blockers; no guaranteed pass or zero-findings goal.

  • 1.lowR8 v1.1 regression: any provider-registry change with no user pick and no click (late EIP-6963 announcement, second wallet announcing, same-account provider object) revokes the accepted displayed sesssource/src/world/auth.ts:287

        this.automaticCleanup('provider-switch',this.gen,this.life,abandoned,held);

    State: open / policy decision required. Blocker: yes until the requester confirms a pick-less registry change is a 'switch' (brief blocker class: unintended session revocation; no privilege gain, so severity Low). Merged from three specialist findings (audit_math b0d5473d, audit_permissions 96cfb0e8, audit_flow 4a612ae0); all three reproduce on the candidate and none on the public parent c4f451b.

    Mechanism (reproduced): providerChanged() now unconditionally bumps gen, clears account/sessionKnown/home and calls automaticCleanup('provider-switch', ..., held). planCleanup (authCleanup.ts:22) returns displayed-session whenever a session is displayed, so POST /api/auth/logout {expectedAddress:} is sent with the live cookie and the Worker revokes the row (204, Set-Cookie clear). This runs (a) with no click and no retained owner (idle PRESENT_ACCEPTED), (b) before the new provider's eth_accounts is read, so also when the new provider holds the session's own account, and (c) when WalletRegistry.current() merely becomes null. WalletPanel.tsx:21 wires onProviderChange to registry.subscribe, and wallet.ts compute()/current() change identity without any pick: window.ethereum -> first announced provider (options.length===1, nothing remembered), or one auto-chosen wallet -> null when a second wallet announces (needsChoice). A returning signed-in visitor whose extension announces after GET /api/auth/session restored the session is therefore signed out on every page load (ended:'revoked'). The parent (c4f451b auth.ts providerChanged) only cleaned up when a flow was active ('if(activeFlow)this.automaticCleanup(...)') and otherwise kept the session as mismatch/account-less. The method's own doc comment (auth.ts:278-281, 'an address other than the session's shows as a mismatch, so owner mode ends until that address signs in') still describes the parent contract, while AUTH_STATE_MACHINE.md row 'account/provider switch | present | any | any | displayed expectedAddress' describes the new one; the account path is asymmetric (accountChanged to the session's own address is a no-op, auth.ts:526).

    Counts per run (candidate): prompts 0, challenge 0, verify 0, cleanup POST 1 (expectedAddress, 204), hints 0, RPC 0. Rows: sessions created 1 / live 0 / revoked 1; challenges used 1 / pending 0 / invalidated 0. Cookie alias: the browser's single session cookie is cleared. cleanupPlans=[{eventId:1,reason:'provider-switch',kind:'displayed-session'}]. Event order P1: WALLET_eth_accounts -> START -> GET /api/auth/session PRESENT(A) -> GET /api/me/home -> eip6963:announceProvider (no pick) -> PROVIDER_SWITCH -> POST /api/auth/logout {expectedAddress:A} 204.

    Separation: reproduced facts = the rows/requests above on candidate and parent with one probe. Team claim (R8_FINAL_CLOSURE LOW-1: 'Account/provider context change still selects the displayed address') is confirmed as implemented; auth-r8 'malformed-provider' and wallet-client controls cover an explicit pick or a switch during a click only, no public test covers a provider-object change with no pick and no click. Inference: real share of late-announcing extensions (unmeasured, injected provider only). Fix preserving the R8 planner: treat only a registry pick (WalletRegistry.choose) or an account change as a switch with cleanup authority; on a passive current() change with no click and no RETAINED owner rebind, drop account and let the new provider's eth_accounts decide (same address: nothing; other: existing mismatch/account-switch path); treat a transition to 'no provider chosen' like a lock (preserve accepted session).

    Variant P1b: announce wallet One first (auto-chosen), tab over registry.current(), then announce wallet Two with nothing remembered -> registry.current()===null, needsChoice true. Variant P2: tab with getProvider:()=>chosen, q.signIn() once, then chosen=provider(A) (same account) and q.notifyProvider().

    Expected (parent c4f451b, same probe, measured): no logout request; sessions created 1 / live 1 / revoked 0; GET /api/auth/session signedIn:true; client session kept; prompts 0 (P2: 1, no new prompt).

    Actual at 7215c5d (measured, all three variants): one POST /api/auth/logout with expectedAddress -> 204; sessions created 1 / live 0 / revoked 1; GET /api/auth/session {signedIn:false}; client session null, ended 'revoked'; prompts unchanged; cleanupPlans [{eventId:1,reason:'provider-switch',kind:'displayed-session'}].

  • 2.lowLOW-5/LOW-6 regression: overlapping /api/me/home reads for one address each repeat the budgeted keyed Alchemy index read (request-start now compared with a live-clock stamp)source/server/ownership.ts:256

              },v=>!again&&isFreshAge(req.now,v.at,fresh?OWNERSHIP_TTL_MS:CANDIDATES_TTL_MS));

    State: open (regression vs public parent c4f451b). Blocker: yes for the LOW-5 closure claim '20 concurrent requests during held delta: one index reload' (it holds only with a frozen fixture clock); not Critical/High/Medium and not an authority failure: the ownerOf epoch holds (1 eth_call) and no ownership is granted; the repeat is bounded by the chain:index budget (20/min per location), so it is not an unbounded keyed RPC. Merged from audit_permissions 7910a647 and audit_flow 69b7ba79.

    Mechanism (reproduced): server/auth.ts:715 captures now at route entry (before readSession, the 'home' limiter and the roster read) and passes it as req.now; req.clock is the live clock (auth.ts:770). In Ownership.proof the index answer is stamped at=req.clock() (ownership.ts:252) and the refused/failed attempt at attemptedAt=req.clock() (:247), but freshness of the candidates cache is judged with the request-start clock: keep at :256 (isFreshAge(req.now,v.at,...)) and discovery keep at :267-268 (isFreshAge(req.now,d.attemptedAt|d.indexed.at,...)). Since R8 isFreshAge rejects negative age (src/shared/freshness.ts:6). R8 also queues same-address callers behind the in-flight update and re-runs proof for each (:228). A queued request whose req.now precedes the stamp the previous request just wrote sees age<0, treats the seconds-old answer as not fresh, calls budget() again and performs its own keyed getNFTsForOwner read (up to 5 pages), stamping an even later at, so the next queued request fails the same way. Any positive Worker latency between route entry and the index read suffices; requests only need to overlap (N tabs reacting to one 'signed-in' hint, a script sending 20 with one cookie: the 'home' bucket allows 20/min per session).

    Impact: the documented discovery cadence (index once per 5 min per address, 30 s with fresh=1: OWNERSHIP_FRESHNESS.md, ownership.ts:21-24) does not hold under overlap; one session can spend the whole per-location chain:index budget each minute, turning other owners' due index reads into recheck:'limited' answers. In the refused-budget case the budget is consulted once per overlapping request in both parent and candidate (not a regression), while the candidate keeps ownerOf at 1 where the parent re-proved 20 times (an improvement).

    Counts (reproduced): direct Ownership class, 20 overlapping home() with req.now=START+i and a live clock that advances in budget()/index/rpc: candidate fresh=false {budget:20,indexReads:20,ownerOfRpc:1}, fresh=true {budget:20,indexReads:20,ownerOfRpc:1}; parent c4f451b same probe {1,1,1}/{1,1,1}. Real Worker + SQLite (tests/wallet-harness.mjs, counting CHAIN_LIMITER keys and fake-Alchemy calls, limiter/chain fetch advance the injected clock): candidate after a 20-request burst index 21 / budget 21 / eth_call 2 vs parent index 2 / budget 2 / eth_call 2; all 20 answers 200 and complete. Refused budget with 5 ms roster latency: candidate budget 20 / rpc 1, parent budget 20 / rpc 20.

    Separation: reproduced = the counts above. Team claim (OWNERSHIP_FRESHNESS.md '20 concurrent requests during held delta: One index reload'; ownership-v11 'twenty refused fresh reads') is measured only with clock()===now and strictly sequential reads, so it cannot see this. Unmeasured: production Cloudflare limiter/Alchemy quota effect (no production requests made). Fix preserving the design: judge candidate/discovery freshness in the same clock domain as the stamps (req.clock?.()??req.now read after the proofing queue wait, as proofNow at :273 already does), or let a queued caller reuse an index answer whose stamp is >= its own req.now (an answer read after the request began is not stale for it); keep rejecting future stamps only for remote/D1-supplied dates. Add a concurrent control (20 overlapping home(), now<clock) asserting budget==1, indexPages==1.

  • 3.lowINFO-1 partially closed: a wallet lock keeps the uncertain committed verify owner, but the wallet's unlock of the SAME account then converts it to a context switch and auto-revokes the committed sessisource/src/world/auth.ts:533

        this.gen++;this.lifecycle.cancel();this.cancelOwners(locked?'lock-reconcile':'context-switch');const g=this.gen;

    State: partial (INFO-1). Improved vs the parent, which revoked at the lock itself; the same revocation is now deferred to the unlock. Blocker: yes for the INFO-1 closure claim as written ('LOCK reconciles uncertain verify, never auto-revokes accepted session') unless the requester accepts 'any later accountsChanged supersedes lock' as policy; no cross-account authority and no confidentiality impact (the user's own just-committed session is revoked and a second signature is required), so severity Low. Merged from audit_permissions e70a8e2d and audit_flow c1046328.

    Mechanism (reproduced with the real AuthClient + Worker + SQLite fixtures): accountChanged(null) marks the retained verify owner 'lock-reconcile' and plans 'reconcile' (no logout). While that owner is still RETAINED (its single reconciliation GET answered 503, or no valid read has happened yet: reconcileLockedOwner schedules nothing further), the wallet's unlock emits accountsChanged([A]) for the very account the click and the owner were bound to. accountChanged(A) sees a!==this.s.account (null), wasFlow=true because retainedOwners.length>0 (:529), and line 533 runs cancelOwners('context-switch'), overwriting the owner's 'lock-reconcile' reason (authLifecycle.abandon rewrites cancellationReason). automaticCleanup('account-switch') with no displayed session plans 'verify-owner' and revokeAbandoned POSTs /api/auth/logout {expectedNonce} with the live cookie the verify installed; the server matches cookie+nonce and revokes. Nothing compares the returning account with owner.account. Real wallets emit exactly this pair (accountsChanged([]) on lock, accountsChanged([A]) on unlock), and unlocking is the natural next user action while the account shows as locked, so the brief's control 'lock-503 then later valid canonical receipt must release lock owner' is defeated whenever the unlock precedes the next read.

    Captured contexts (single tab, single cookie jar): owner flowId 1 account A; lock -> gen+1; unlock -> gen+2; cookie alias = session S1 created by the click's verify (nonce N1). Counts: prompts 1, challenge 1, verify 1 (200, committed, Set-Cookie applied), reconciliation GET 1 (503), cleanup POST 1 (expectedNonce, 204), hints 0, RPC 0. Rows before unlock: sessions created 1 / live 1 / revoked 0, challenge used 1, owner RETAINED reason lock-reconcile, direct GET /api/auth/session signedIn:true. After unlock: live 0 / revoked 1, signedIn:false, owner CONSUMED reason context-switch, client session null. cleanupPlans: [{1,lock,reconcile},{2,verify-settled,reconcile},{3,account-switch,verify-owner}] (P4) or [{1,lock,reconcile},{2,account-switch,verify-owner}] (H2).

    Separation: reproduced = rows/requests above on candidate and parent. Team claim: auth-v11 covers lock->503->restore()->stop and lock->stop plus the lock-idle/lock-active kernels; no public control performs lock -> unlock(same account) while the owner is RETAINED. Unmeasured: real wallet lock/unlock event shapes beyond the injected provider. Fix preserving intended behaviour: in accountChanged, when a retained owner has cancellationReason 'lock-reconcile' and a===owner.account (same provider), keep the reconciliation-only disposition and run reconcileLockedOwner (canonical post-fence read) instead of cancelOwners('context-switch'); only an account different from owner.account is a switch. Optionally retry the reconciliation read on a bounded timer/visibility so the owner does not sit unresolved.

    Case P4 (verify held before the Worker, lock while in flight, reconciliation 503, unlock same account with reads healthy):

    import {setup,newAccount,provider,tab,ready,until,flush,rows,prompts,logouts} from '../tests/auth-r7-fixtures.mjs';

    const w=setup(),A=newAccount(),b=w.browser(),p=provider(A);let bad=false,gate=null,release;

    const q=tab(w,b,p,{beforeSend:async path=>{if(path==='/api/auth/verify'&&gate)await gate;},intercept:async(path,r)=>path==='/api/auth/session'&&bad?new Response('{"error":"AUTH_UNAVAILABLE"}',{status:503}):r});

    await ready(q);gate=new Promise(r=>release=r);const flow=q.signIn();await until(()=>q.events.some(e=>e.kind==='route'&&e.path==='/api/auth/verify'));

    p.switchTo(null);await flush(5);bad=true;release();await flow;await flush(20);await new Promise(r=>setTimeout(r,20));

    console.log('mid',rows(w).counts,q.c.lifecycleSnapshot.cleanup,logouts(q).length); // live 1, RETAINED lock-reconcile, 0 logouts

    bad=false;p.switchTo(A);await flush(20);await new Promise(r=>setTimeout(r,30));await flush(20);

    console.log('after',rows(w).counts,q.c.lifecycleSnapshot.cleanup,logouts(q).map(e=>({nonce:e.nonceAssertion,status:e.status})),await (await b.get('/api/auth/session')).json(),prompts([p]));

    Case H2: intercept returns the verify 200 with body '{' (headers/Set-Cookie applied, body invalid) and sets bad=true so the reconciliation GET answers 503; then p.switchTo(null); then p.switchTo(A).

    Expected (INFO-1 closure: preserve the committed session; a valid post-fence read releases the owner): 0 logout requests after the unlock, sessions live 1, GET /api/auth/session signedIn:true, owner RELEASED after the next valid read.

    Actual at 7215c5d (measured, both cases): after lock: sessions created 1 / live 1 / revoked 0, owner RETAINED cancellationReason 'lock-reconcile', logouts 0; after unlock(A): POST /api/auth/logout {expectedNonce} -> 204, sessions live 0 / revoked 1, GET /api/auth/session {signedIn:false}, owner CONSUMED cancellationReason 'context-switch', client session null, prompts 1 (the signature is wasted). Parent c4f451b (same probe): the lock itself already sent the nonce logout (H2: live 0 after lock; P4: challenge invalidated 1, sessions created 0), so the candidate is better at the lock event and identical in end state.

  • 4.lowLOW-2 side effect (regression vs parent): a sibling-tab channel message while the wallet prompt is open makes the client silently discard the valid signature; the same sign-in needs a second personal_source/src/world/auth.ts:442

          if(!canSign()){this.set({phase:'idle',notice:this.sessionUnknown()?'session-unknown':null});return;}

    State: open (new in R8 v1.1; parent c4f451b completes the sign-in on the same event order). Blocker: no for authority (fails closed: no session is created, the signed challenge stays pending until its server deadline); listed because one user intent ends up needing two wallet signatures with no notice explaining that the first was dropped, which the brief counts under unintended prompts. Severity Low. From audit_flow 521e4207.

    Mechanism (reproduced): the post-signature gate canSign() (auth.ts:421) requires click.preflight.readSeq===this.sessionReads. The channel listener (auth.ts:257) calls restore() for every message regardless of a busy click (visible() at :181 does check !this.busy). That ordinary read increments sessionReads, so after the prompt returns the sequence no longer matches even though the newer canonical answer is the same ABSENT (lifecycle.know(ABSENT) keeps the receipt, only the sequence comparison fails). The pre-flight stage has a one-shot re-read for exactly this overtaking case (auth.ts:386-389); the post-challenge (:436) and post-signature (:442) gates do not: line 442 ends the click with phase idle and notice null (sessionUnknown() is false because knowledge is ABSENT). Wallet prompts stay open for seconds to minutes, so the window is wide: any BroadcastChannel message from a same-origin tab (a sibling's signed-out after its own logout or switch, or a hint for a session already cleared again) triggers it. If the newer read says PRESENT/UNKNOWN the existing knowledge check already blocks, so accepting a newer valid ABSENT would not weaken the gate.

    Counts (candidate): prompts 1, challenge 1, verify 0, cleanup 0, hints received 1, session GETs 3 (page load, click preflight, hint read); rows: sessions created 0; challenges 1: used 0 / pending 1 / invalidated 0; no cookie; client phase idle, sessionKnown true, session null, notice null. Event order: START -> SIGN_CLICK -> GET session ABSENT (readSeq n) -> POST challenge 200 -> personal_sign opened -> CHANNEL_MESSAGE -> GET session ABSENT (readSeq n+1) -> signature returned -> canSign() false -> click ends. Parent: prompts 1, verify 1 (200), sessions created 1 / live 1, challenge used 1.

    Separation: reproduced = the above on candidate and parent. Team claim: AUTH_STATE_MACHINE.md line 11 ('A newer ordinary read invalidates a receipt by read ordering; a valid superseding read permits at most one new per-click GET') is implemented only before the challenge. Unmeasured: real browser BroadcastChannel timing. Fix direction: mirror the pre-flight rule after the prompt (accept a superseding read whose knowledge is valid ABSENT as the click's receipt, or perform the one per-click re-read before verify), or skip/defer the channel-triggered restore while a click is busy as visible() does; if the click must still end, set a notice (e.g. session-unknown/challenge-lost) so the discarded signature is not silent.

  • 5.lowOwnership request queued behind a failing proof inherits that failure instead of re-evaluating with its own proof (pre-existing, contradicts OWNERSHIP_FRESHNESS.md serialisation rule)source/server/ownership.ts:228

        if(pending)return pending.then(()=>this.proof(address,owners,agents,req,fresh,again));

    State: open, not a regression (identical on public parent c4f451b). Blocker: no. It is fail-closed (503 OWNERSHIP_UNAVAILABLE, never an empty complete home), grants no authority and expands no method or header, so it is an availability defect, not an Auth/ownership invariant failure. From audit_economics 57507b65.

    Mechanism (reproduced): proof() serialises per-address updates by chaining a waiting caller on the in-flight update with pending.then(onFulfilled) only. When the in-flight update rejects (a first or expired-epoch proof whose Multicall3 ownerOf eth_call failed, or a proof completing at/after its 30 s deadline, :292), the rejection propagates through .then() to every caller queued behind it. The queued caller never runs its own update(): no ownerOf RPC is attempted for it even if the node has recovered, and its own captured roster and fresh intent are not re-evaluated. This contradicts OWNERSHIP_FRESHNESS.md line 20 ('A caller waiting behind another request re-evaluates its own captured roster and fresh intent') and the stated availability design ('First/expired proof failures ... their retries remain unavailable and are bounded by existing request limiters'): the waiter is refused without any retry. The existing ownership-v11 controls queue callers only behind successful updates.

    Counts (reproduced): index reads 1, ownerOf RPC 1 (the failed one), lane calls 0; first request rejects OWNERSHIP_UNAVAILABLE (correct), second (queued, node healthy) also rejects OWNERSHIP_UNAVAILABLE with no RPC of its own; a third request afterwards succeeds (eligible 1, RPC 2). Parent c4f451b: identical.

    Separation: reproduced = the above. Team claim: the serialisation rule in OWNERSHIP_FRESHNESS.md is only partially implemented. Minimal fix preserving the serialisation design: chain on settlement rather than fulfilment, e.g. return pending.then(()=>this.proof(...),()=>this.proof(...)) (or pending.catch(()=>{}).then(()=>this.proof(...))), so the waiter performs its own epoch evaluation and proof after the predecessor settles; a re-run still passes the same budget/lane/limiter gates, so the bounded-RPC argument is unchanged.

    Offline, synthetic fixtures only. From source/ with npm ci --ignore-scripts, tmp/oq.test.mjs, node --test tmp/oq.test.mjs (same gateway/fetcher scaffold as the overlap probe, plus a hold gate and a fail flag on the eth_call):

    const deferred=()=>{let resolve;return {promise:new Promise(r=>resolve=r),resolve};};const st={live:START,rpc:0,failRpc:false,holdRpc:null};

    // in the eth_call branch of the fetcher: st.rpc++; const willFail=st.failRpc; if(st.holdRpc){const g=st.holdRpc;st.holdRpc=null;g.started.resolve();await g.release.promise;} if(willFail)return new Response('{}',{status:502}); ...normal aggregate3 answer...

    const gate={started:deferred(),release:deferred()};st.holdRpc=gate;st.failRpc=true;

    const first=o.home(A,req(START),false);await gate.started.promise; // first proof's RPC is held

    const second=o.home(A,req(st.live),false); // queued behind the held first proof

    st.failRpc=false; // node healthy again before the first failure is observed

    gate.release.resolve();

    await first.catch(e=>console.log('first',e.message)); await second.then(v=>console.log('second ok',v.eligible),e=>console.log('second',e.message,'rpc',st.rpc));

    console.log('third',(await o.home(A,req(st.live),false)).eligible,'rpc',st.rpc);

    Expected (OWNERSHIP_FRESHNESS.md): the queued second request performs its own proof after the first settles: RPC count 2, second request resolves with eligible 1.

    Actual at 7215c5d (measured): first OWNERSHIP_UNAVAILABLE; second OWNERSHIP_UNAVAILABLE with rpc still 1 (no RPC of its own); third succeeds (eligible 1, rpc 2). Parent c4f451b: identical output.

  • 6.lowLOW-6 side effect (regression vs parent): a good world snapshot whose Worker fetchedAt is ahead of the browser clock is classified as a failed read (retry ladder, permanently 120 s for a lagging clocksource/src/world/cadence.ts:62

        if(core.some(s=>s.fetchedAt===null||!isFreshAge(now,s.fetchedAt,Number.MAX_VALUE)))return false;

    State: policy decision with an unmeasured load/UX side effect; open. Blocker: no (not an authority issue; load and display only). Merged from audit_math c5dd4210 and audit_permissions b7888aae.

    Mechanism (reproduced): worldReadResult() compares the Worker's epoch fetchedAt (server/gateway.ts:212, fetchedAt=this.now()-ageMs, Cloudflare's clock) with the browser's Date.now() through isFreshAge, which returns false for any negative age (src/shared/freshness.ts:6). A client whose wall clock is behind the stamp by more than the response latency sees a state:'fresh' sample as 'future' and worldReadResult returns false, the same value as a transport failure. startPoll() (cadence.ts:98-103) then increments failures and schedules nextDelay(false,...): 5 s, 15 s, 30 s, 60 s, then 120 s for ever, instead of REFRESH_MS=900 s after a good read, while the valid data it just received is displayed. The effect is transient when the lag is smaller than the sample's age at the next retry (one or a few extra reads) and persistent for a device whose clock lags by more than the gateway sample age (up to UPSTREAM_TTL_MS, 5 min): that client polls /api/world/snapshot every 120 s (7.5x the designed rate) for the whole session. The same comparison in marketView (market.ts:112) and floorView (market.ts:93) labels a Worker-fallback quote 'stale' (weather 'unknown', floor null) for the same skewed client. Before R8 (c4f451b cadence.ts:59) a future stamp counted as a good read ('behind'/true). FRESHNESS_BOUNDARIES.md records the intent ('invalid/future source fetchedAt cannot count as a good read') and tests/freshness-v11.test.mjs pins fetchedAt 1001 vs now 1000 => false, but neither considers that 'not good' is mapped onto the failure retry ladder rather than onto 'behind' (one bounded follow-up) or a success-for-scheduling. Clock skew of seconds on consumer devices is routine (siwe.ts allows 10 minutes of skew for the sign-in message for that reason).

    Separation: reproduced = the probe below on candidate and parent. Team claim: FRESHNESS_BOUNDARIES.md policy as stated is implemented. Inference/unmeasured: the share of real visitors with negative skew; WorldApp.tsx (withheld) is assumed to feed worldReadResult into startWorldPoll as the public fixture comments describe. Fix that keeps future stamps untrusted: keep refusing to label a future-dated sample fresh, but return 'behind' (or true) for the scheduler when the samples are fresh and the only defect is a bounded negative age (e.g. up to FOLLOW_UP_MS or the SIWE skew allowance), and allow the same bounded skew for remote stamps in marketView/floorView, never rewriting the stamp.

  • 7.infoGateway shared-copy warm accepts a record dated up to 60 s in the future and rewrites its fetchedAt to now, contrary to the frozen freshness policy ('never synthesize a future stamp', 'reject remote fsource/server/gateway.ts:256

          const fetchedAt=Math.min(record.fetchedAt,at);

    State: accepted limit / unchanged since the public parent (gateway.ts is not in the R8 change set); reported because the task's freshness controls require rejecting remote future timestamps without rewriting them as now and FRESHNESS_BOUNDARIES.md states 'never synthesize a future stamp'. Blocker: no. From audit_math d6cd077d.

    Mechanism (reproduced): ReadGateway.warm() (gateway.ts:253-259) seeds a cold isolate from the per-colo Cache API copy written by another isolate. Line 254 tolerates age>=-60_000 (a record dated up to one minute ahead of this isolate's clock) and line 256 stores fetchedAt=Math.min(record.fetchedAt,at), re-dating a future record as read 'now', then validUntil=max(entry.validUntil,fetchedAt+ttl) gives it a full UPSTREAM_TTL_MS from this clock and labels it 'fresh' to clients and to the ownership roster read (Ownership.world() uses gateway.source('swarm')). Impact is bounded: the writer is another isolate of the same Worker in the same Cloudflare location, so the skew is Cloudflare's own inter-isolate clock skew, and the roster only names candidates (ownerOf still proves them). It is a documented-policy inconsistency rather than an authority defect, and the exact boundary (age===-60_000 accepted) is untested.

    Separation: reproduced = probe below (candidate and parent identical). Unmeasured: real inter-isolate skew. Fix if the policy is to be uniform: reject age<0 as isFreshAge does elsewhere, or keep the record's own fetchedAt unmodified and let label()/servable() judge it.

    From source/ (offline, injected fetch and clock): node --test tmp/gw.test.mjs with

    const {ReadGateway,SHARED_SHAPE}=await import('../server/gateway.ts');let t=1_000_000;const urls=[];

    const g=new ReadGateway(async u=>{urls.push(String(u));return new Response(JSON.stringify({seats:{},owners:[],count:0,workers:[]}),{status:200});},()=>t,{sharedWaitMs:50});

    const shared={async get(k){return k==='swarm'?{v:1,shape:SHARED_SHAPE,key:k,data:{seats:{},owners:[],at:1},fetchedAt:t+59_000}:undefined;},async put(){}};

    const s1=await g.source('swarm',undefined,shared);console.log(s1.state,s1.fetchedAt,t);t+=4*60_000;const s2=await g.source('swarm',undefined,shared);console.log(s2.state,s2.fetchedAt,t,urls.filter(u=>u.includes('/swarm')).length);

    Expected under the stated policy: a shared record dated 59 s in the future is not usable as current data (ignored, or kept with its own future fetchedAt so downstream freshness gates reject it).

    Actual at 7215c5d (measured): prints fresh 1000000 1000000 (accepted and re-dated to this isolate's now) and at +4 min still fresh with fetchedAt 1000000; parent c4f451b identical.

  • 8.infoPublic scheduler test writes evidence artifacts outside source/ into the review repository root, embedding an absolute local path and a non-reproducible run idsource/tests/auth-reference-scheduler.test.mjs:9

    const artifactRoot=resolve(import.meta.dirname,'../../evidence/reference-scheduler');

    State: open (hygiene). Blocker: no. From audit_economics 553671b9.

    The recorded public filtered-subset command (Submission7_R8Closure/TEST_RESULTS.json) includes tests/auth-reference-scheduler.test.mjs, whose save() helper (line 18) writes into resolve(import.meta.dirname,'../../evidence/reference-scheduler'), i.e. /evidence/reference-scheduler, one level above the published source/ tree. A reviewer who runs the exact recorded command from source/ ends up with untracked JSON files in the review repository root (fixed--.json, focused-.json, gate---RESULT.json, LATEST.json). Each fixed/focused file embeds provenance().sourceRoot, an absolute local path, and the gate file name contains a wall-clock timestamp and random UUID, so the artifacts are not byte-reproducible and are easy to commit by accident into a package whose manifests (submission7-r8closure-published-source.json, SHA256SUMS, BOUNDARY_CHECK.json) do not cover them; TEST_RESULTS.json's sourceUnchangedDuringRun receipt only speaks for source/.

    Reproduced fact: after the recorded command in a scratch copy of source/, the sibling directory evidence/reference-scheduler held 18 JSON files (13 fixed-, 3 focused-, 1 gate-*-RESULT.json, LATEST.json) and fixed-0-lost-hint.json contains "sourceRoot": "". Minimal fix: write artifacts under a path inside source/ that .gitignore already excludes (source/.gitignore ignores tmp/), or honour an explicit output environment variable and skip persistence when it is unset; record the artifact location in TEST_RESULTS.json if artifacts are meant to be part of the receipt.

    From a clean checkout of commit 7215c5d: cd source && npm ci --ignore-scripts && node --test --test-reporter=tap --test-concurrency=3 tests/auth-reference-scheduler.test.mjs then cd .. && git status --short && ls evidence/reference-scheduler | wc -l && grep -o '"sourceRoot": "[^"]*"' evidence/reference-scheduler/fixed-0-lost-hint.json.

    Expected: no files created outside source/ (or only under an ignored path).

    Actual (measured on a scratch copy): the directory evidence/reference-scheduler is created beside source/ with 18 JSON files, the fixed/focused files carry the absolute sourceRoot of the running machine, and the gate RESULT file name carries a timestamp and UUID; in the repository this appears as ?? evidence/ in git status.

    Findings

    #SeverityStateBlockerWhereWhat fails
    1Lowopen (regression)yes — ownership cadence invariant; bounded, not an unbounded keyed RPCsource/server/ownership.ts:25620 overlapping /api/me/home requests for one address make 20 keyed NFT-index reads and spend 20 chain:index tokens (parent: 1). ownerOf stays at 1 RPC.

    4Infoaccepted limitnosource/src/world/cadence.ts:62A browser clock behind the Worker's stamp turns a good read into a failure.
    • Finding 1: cache freshness is judged with the request-start now, while the index answer is stamped with the live clock, so every queued request rejects the answer just read. One session can drain the 20/min per-location index budget. With the budget refusing, the same burst calls budget() 20 times; the team's "x20 costs one budget attempt" control is sequential and cannot see this.
    • Finding 2: with the verify body invalid and the reconcile read returning 503, lock sends no logout and the session row stays live. Unlock to the same account then plans account-switch / verify-owner and the session ends revoked (live 0, revoked 1). The parent sent the same logout at the lock, so the end state matches the original defect.
    • Finding 3: this fires when the new provider holds the same account, and when the provider merely becomes null. The parent kept the session. The cleanup matrix in AUTH_STATE_MACHINE.md documents it, but the doc comment at auth.ts:278-281 says the opposite. How often a late EIP-6963 announcement lands after session restore in a real browser is inference, not measured.
    • Finding 4: with the client 2 s behind, polling drops to the 5 s … 120 s retry schedule instead of 15 min, and market weather and floor are hidden. It is transient for small lag and persistent only when the lag exceeds the sample's age.

    My measurements, separate from team claims

    • Public subset: 518/518, zero fail/skip/cancel, same command as the receipt, on Node v24.21.0 (the receipt used v24.19.0).
    • Reference scheduler: 500/500 schedules, 428 digests, 3,572 Worker calls, 5,477 SQLite comparisons, 3,402 projections, 38 pre-header failures — all match the receipt.
    • Public tsc: exit 2 with 14 TS2307 and 1 TS7006, matching the receipt's counts; the stdout hash differs.
    • Worker dry-run: exit 0 after pointing HOME at a writable directory (the first attempt failed on a log-directory permission). My bundle is 314,107 bytes against the receipt's 318,097, so byte parity is an unavailable comparison.
    • Hashes: SHA256SUMS verifies; both prior-review originals on main match the captured SHA-256 values.
    • Unchanged surfaces: wallet methods are still eth_accounts, eth_requestAccounts and personal_sign; server/auth.ts, the Worker, headers and migrations are identical to the parent.

    Not measured

    • The private 1,528-test suite, full TypeScript/Vite build, and the frozen-f9 seed replays are team claims I could not run.
    • The candidate is not deployed, so production parity is unmeasured and remains a release gate.
    • No real browsers, wallets, Cloudflare limiter or WAF behaviour were exercised; providers, clocks and upstreams were injected.

    • lowR8 freshness helper turns the per-address proof queue into repeated keyed NFT-index reads: N overlapping /api/me/home requests spend N chain:index budget tokens (parent: 1)source/server/ownership.ts:256

      State: open (regression introduced by the LOW-5/LOW-6 repair; not present at public parent c4f451b). Blocker: yes by the brief's own list (ownership cadence invariant failure on a keyed upstream read), though bounded by the chain:index budget, so it is NOT an unbounded keyed RPC and not an authority bypass; severity Low.

      Mechanism (reproduced). server/auth.ts:715 captures now at handler start and passes it as req.now, while req.clock is the live clock (auth.ts:770). In Ownership.proof the index answer is stamped at=req.clock() (ownership.ts:252) but its cache freshness is evaluated with the request-start clock: candidates keep isFreshAge(req.now,v.at,...) (line 256) and discovery keep isFreshAge(req.now,d.indexed.at,...) / isFreshAge(req.now,d.attemptedAt,...) (lines 267-268). R8 also changed concurrent callers from sharing the in-flight result to being queued and re-running proof (line 228). A queued request that entered the Worker before the first request's index read began has req.now < v.at, so the new isFreshAge (negative age => not fresh, src/shared/freshness.ts:5-6) rejects the answer that was read milliseconds ago; the queued request calls budget() and indexedNfts() again and stamps an even later at, so the next queued request fails the same test. Every request of a burst therefore performs its own keyed Alchemy getNFTsForOwner read. The ownerOf epoch itself holds (proofNow uses req.clock, line 273): ownerOf RPC count stays 1.

      Impact. The documented cadence (index once per 5 min per address, 30 s with fresh=1; OWNERSHIP_FRESHNESS.md, ownership.ts:21-24) does not hold under overlap, with or without fresh=1. One signed-in session (any wallet; no seat needed) can send its 20 'home' requests/min in parallel and consume the whole 20/min per-location chain:index budget, so other owners in that location get recheck:'limited' answers (roster + kept index only; a newly bought seat is not discovered except via the 1/min lane). In the parent the same session could cause at most 2 index reads/min per address. Benign overlap (two tabs loading, visible()+poll) also double-reads. In the refused-budget case the same burst calls budget() 20 times (20 limiter consultations and 20 D1 keptIndex reads) where the closure table claims 'repeated refused refresh x20 costs one RPC / one budget attempt'; the team control tests/ownership-v11.test.mjs 'twenty refused fresh reads' is strictly sequential with now==clock, so it cannot see this.

      Separation of evidence. Reproduced: counts below, on the pinned source and on c4f451b with one unchanged probe. Team claim not reproduced under overlap: 'x20 costs one budget attempt'. Inference: production impact on the Cloudflare limiter/Alchemy quota (not measured; no production requests made). Unmeasured: real Worker latency between handler start and index read (any positive latency suffices; requests only need to overlap).

      Fix that preserves the design: evaluate discovery/candidate cache freshness against the completion-side clock (req.clock?.()??req.now, as proofNow already does), or have a queued caller reuse an index answer whose stamp is >= its own req.now (an answer read after the request began is by definition not stale for it); keep rejecting future stamps only for remote/D1-supplied dates. Add a concurrent control (20 overlapping home(), now<clock) asserting budget==1, indexPages==1.

      Offline, synthetic fixtures only.

      In a copy of source/ with npm ci, drive the real Ownership class with the production wiring (req.now = request-start time, req.clock = live clock that advances 5 ms in gateway.source, 30 ms in budget(), 200 ms per index read, 100 ms per eth_call; roster and index both name seat 7 owned by A).

      Issue 20 overlapping calls ownership.home(A,{chain,now:START+i,clock:()=>live,budget},fresh) for i=0..19 and await Promise.all.

      Expected (and actual on parent c4f451b, same probe via V11_SOURCE): budget()=1, index reads=1, ownerOf eth_call=1 for fresh=false and fresh=true.

      Actual on pinned 7215c5d: fresh=false -> {budget:20,indexReads:20,ownerOfRpc:1}; fresh=true -> {budget:20,indexReads:20,ownerOfRpc:1}; all 20 views eligible=1.

      Budget-refusing variant (budget returns false): expected budget()=1 (closure table: x20 refused costs one budget attempt), actual budget:20, indexReads:0, ownerOfRpc:1, all views recheck:'limited' (parent: budget:1).

      Failing state: any request for address A whose handler-start now is earlier than the at stamp of an index answer read by an overlapping request for A (req.now < v.at).

    • lowINFO-1 only partially closed: wallet lock preserves an uncertain committed session, but the wallet's unlock event for the SAME account then auto-revokes it by noncesource/src/world/auth.ts:533

      State: partial (INFO-1). Blocker: yes for the INFO-1 closure claim (Auth invariant 'LOCK reconciles uncertain verify, never auto-revokes' is defeated by the paired unlock event); no confidentiality/authority impact - the effect is an unintended revocation of the user's own just-committed session and a forced second signature. Severity Low/Info.

      Mechanism (reproduced with the real AuthClient + Worker + SQLite fixtures). accountChanged(null) marks the retained verify owner 'lock-reconcile' and plans 'reconcile' (no logout). While that owner is still RETAINED (its reconciliation GET answered 503/invalid, or the verify response has not been observed yet), the wallet's unlock emits accountsChanged([A]) for the same account the click and owner were bound to. accountChanged(A) sees a!==this.s.account (null), wasFlow=true because retainedOwners.length>0 (line 529), and line 533 runs cancelOwners('context-switch'), overwriting the owner's 'lock-reconcile' reason. automaticCleanup('account-switch') then plans 'verify-owner' and revokeAbandoned POSTs /api/auth/logout {expectedNonce}; the server matches the live cookie+nonce and revokes. Nothing compares the returning account with owner.account, so re-announcing the identical account is treated as a context switch. Real wallets emit exactly this pair (accountsChanged([]) on lock, accountsChanged([A]) on unlock).

      Captured contexts: single tab, single cookie jar; owner flowId 1, account A, generation g; lock event -> gen g+1; unlock event -> gen g+2; cookie alias = session S1 created by the click's verify (nonce N1).

      Prior baseline control: on parent c4f451b the lock itself sent the nonce logout (logouts after lock = 1); on the candidate the same revocation is merely deferred to the unlock (logouts after lock = 0, after unlock = 1). End state is identical to the pre-repair defect.

      Not covered by the team matrix: tests/auth-v11.test.mjs covers lock->503->restore()->stop and lock->stop, and the lock-idle/lock-active kernels, but no lock->unlock(same account) while the owner is RETAINED.

      Fix preserving intended behaviour: in accountChanged, when a retained owner has cancellationReason 'lock-reconcile' and a===owner.account, keep the reason and re-run reconcileLockedOwner (canonical post-fence read) instead of cancelOwners('context-switch'); only an account different from owner.account should convert it to a nonce cleanup.

      Offline fixtures (tests/auth-r7-fixtures.mjs: setup/newAccount/provider/tab), in a copy with npm ci.

      Case H2: tab intercept returns the verify 200 with body '{' (headers/Set-Cookie applied, body invalid) and answers GET /api/auth/session with 503 afterwards.

      Steps: await ready(q); await q.signIn() (1 personal_sign, 1 challenge, 1 verify; Worker commits session S1: sessions created=1 live=1 revoked=0; client UNKNOWN, owner RETAINED); p.switchTo(null) (lock) -> plan {reason:'lock',kind:'reconcile'}, logouts=0, live=1 (correct); p.switchTo(A) (unlock, same account).

      Expected: no logout, S1 stays live, owner reconciles on the next valid canonical read.

      Actual: plan {reason:'account-switch',kind:'verify-owner',flowId:1}; one POST /api/auth/logout with expectedNonce -> 204; rows created=1 live=0 revoked=1; challenges used=1 pending=0 invalidated=0; GET /api/auth/session -> {signedIn:false}; prompts=1 (a second signature is now needed).

      Case H1 (verify request held before reaching the Worker, lock, unlock same account, release): plans [lock/reconcile, account-switch/verify-owner]; nonce logout 204 invalidates the pending challenge (challenges invalidated=1, used=0), the signed verify is refused, sessions created=0.

      Parent c4f451b with the same probe (AUTH_R7_SOURCE=../baseline): identical final rows, with the logout sent at the lock instead (logoutsAfterLock=1).

    • lowRegression vs parent: any provider-registry change on an idle signed-in page (late EIP-6963 announcement, second wallet announcing, chooser pick of the same account) revokes the accepted session with source/src/world/auth.ts:287

      State: policy decision required (documented in AUTH_STATE_MACHINE.md cleanup matrix row 'account/provider switch | present | displayed expectedAddress', but contradicted by this method's own doc comment at auth.ts:278-281, 'an address other than the session's shows as a mismatch, so owner mode ends until that address signs in', and by parent behaviour). Blocker: decision needed before closure - it is an unintended session mutation (revocation) triggered without a click; not a privilege gain. Severity Low.

      Mechanism (reproduced). providerChanged() now unconditionally bumps gen, sets sessionKnown:false/home:null and calls automaticCleanup('provider-switch',...,held) (line 287). planCleanup returns 'displayed-session' whenever a session is displayed, so POST /api/auth/logout {expectedAddress:} is sent with the live cookie and the server revokes the session. This happens (a) with no click and no retained owner (pure idle PRESENT_ACCEPTED), (b) before the new provider's eth_accounts is read, so even when the new provider holds the very same account as the session, and (c) when the registry's current() merely becomes null. WalletPanel wires onProviderChange to WalletRegistry.subscribe, and WalletRegistry.current() changes without any user action when a wallet announces after start: window.ethereum -> the first announced provider object, or one chosen wallet -> null when a second wallet announces and nothing is remembered (wallet.ts compute(): options.length===1?options[0]:null). A returning signed-in visitor whose extension announces after GET /api/auth/session has restored the session is therefore silently signed out (ended:'revoked') and must sign again; a page-injected script that dispatches a well-formed eip6963:announceProvider event can cause the same (same-origin script only; noted as inference, not measured in a browser). By contrast accountChanged() to the same address is a no-op (line 531), so the two context events are asymmetric.

      Parent c4f451b: providerChanged only cleaned up when a flow was active (activeFlow / retained owners); an idle accepted session was kept and shown as account-less or mismatch.

      Separation: reproduced - rows/requests below on candidate and parent with one probe. Inference - frequency of late EIP-6963 announcements relative to the session GET in real browsers (unmeasured; injected provider only). Team claim 'Account/provider context change still selects the displayed address' (LOW-1) is confirmed as implemented; the question is whether an idle, clickless provider-object change is a context change that should revoke.

      Fix options preserving the R8 planner: for an idle page (no click, no RETAINED owner) keep the session, drop account, and let the new provider's eth_accounts decide (same address: nothing; other address: the existing mismatch view / account-switch cleanup); or at minimum bind first and revoke only if the new provider reports a different account.

      Offline fixtures (tests/auth-r7-fixtures.mjs) with getProvider:()=>chosen.

      Steps: await ready(q); await q.signIn() with provider p (account A) -> sessions created=1 live=1, client session A displayed, 1 personal_sign.

      Then (H6) chosen=next where next=provider(A) (same account A) and q.notifyProvider(); or (H6b) chosen=null and q.notifyProvider().

      No click, no sign-out.

      Expected (parent c4f451b, same probe via AUTH_R7_SOURCE=../baseline): logouts=[], rows live=1 revoked=0, GET /api/auth/session {signedIn:true}, client session kept.

      Actual on pinned candidate, both variants: cleanupPlans=[{eventId:1,reason:'provider-switch',kind:'displayed-session'}]; one POST /api/auth/logout with expectedAddress -> 204; rows created=1 live=0 revoked=1 (challenges used=1, pending=0, invalidated=0); GET /api/auth/session -> {signedIn:false}; client session=null, ended='revoked'; prompts stay 1, no new challenge/verify.

    • infoLOW-6 future-stamp rejection has zero skew tolerance: a browser clock behind the Worker's fetchedAt turns a good world read into a failure (retry cadence instead of 15 min) and hides market weather/flsource/src/world/cadence.ts:62

      State: accepted limit / policy decision (the brief requires rejecting remote future timestamps without rewriting them; this is the measured side effect, absent at parent c4f451b). Blocker: no. Not an Auth/ownership authority issue.

      Mechanism (reproduced). worldReadResult, marketView (market.ts:112) and floorView (market.ts:93) compare a remote epoch stamp (the Worker's fetchedAt, or Alchemy's retrievedAt) with the browser's Date.now() through isFreshAge, which returns false for any negative age. Whenever the viewer's clock is behind the stamp - by 1 ms in the team's own control (tests/freshness-v11.test.mjs 'remote cadence cannot certify future...': fetchedAt 1001 vs now 1000 => false) - a state:'fresh' world read is classified as failed. startPoll then counts failures and schedules FIRST_RETRY_MS/RETRY_MS (5 s, 15 s, 30 s, 60 s, 120 s, ...) instead of REFRESH_MS (900 s), and the same sample yields market state 'stale', weather 'unknown' and floor null. The effect is transient when the lag is smaller than the sample's age at the next retry (one extra read), and persistent for a device whose clock lags by more than the gateway's sample age (about UPSTREAM_TTL_MS, 5 min): that client polls /api/world/snapshot every 120 s (7.5x the designed rate) and never shows market weather from the Worker fallback or the seat floor. Inference (not measured): share of real visitors with such skew; the withheld WorldApp/SourceNotes UI may additionally render the read as failed.

      Fix that keeps future stamps untrusted: allow a small bounded skew (for example treat -SKEW<=age<0 as age 0, with SKEW of a few seconds to a minute) for remote stamps only, or classify a future stamp as 'behind' (one follow-up read) rather than as a failed read, while still never rewriting the stamp.

      node --test probe importing src/world/cadence.ts and src/world/market.ts.

      Input: s={state:'fresh',data:{},fetchedAt:T}, client now=T-2000. worldReadResult({swarm:s,workers:s},T-2000): expected true (parent c4f451b: true); actual false.

      Driving startWorldPoll with that read and a fake timer env: scheduled delays [5000,15000,30000,60000,120000,120000,120000], failures=7 (parent: [900000 x7], failures=0). marketView({state:'fresh',fetchedAt:T,data:{priceUsd:8,change24h:-30,priceNative:.003,...},extras:{floorEnabled:true,floor:{floorEth:2.5,marketplace:'OpenSea',fetchedAt:T}}},T-2000): actual {state:'stale',weather:'unknown',floor:null}; parent {state:'fresh',weather:'thunderstorm',floor:{floorEth:2.5,floorUsd:6666.67}}.

    4LOW-2 side effect: a sibling-tab hint read while the wallet prompt is open silently discards the valid signaturesource/src/world/auth.ts:442openno (fails closed)
    • Finding 1: 20 overlapping reads cost 20 budget calls and 20 index reads on the candidate, against 1 and 1 on parent c4f451b. The ownerOf proof is still read once. The cause is that the request-start time is compared with stamps taken later from the live clock, so a queued request sees a negative age. One session can spend the per-location index budget in one burst.
    • Finding 2: The parent kept the session in the same cases. It triggers with no user action when a second wallet extension announces itself late, and when the newly picked wallet holds the same account. A related case on the account path: the wallet returns to the session's own address during a click, and the session is revoked.
    • Finding 3: Before the unlock the session row is live and the canonical read says signed in; after it the row is revoked. The parent revoked at the lock itself, so this is improved but not closed.
    • Finding 4: The candidate sends no verify, creates no session and shows no notice; the parent completes the sign-in. The same intent then needs a second personal_sign.

    Measurements (mine, separate from team claims)

    • Public subset: the recorded 17-file command gave 518/518, with no failures, skips or cancellations, on Node v24.21.0 (the team receipt used v24.19.0).
    • All public test files: tests/*.test.mjs gave 641 tests, 637 pass, 4 fail. Three are whole-file failures (home-entry, ownership, wallet-client); the snapshot's TESTS/README.md attributes these to withheld modules, and I did not capture the load errors myself. The fourth is a deploy-evidence test, which I did not investigate.
    • TypeScript: tsc --noEmit exits 2 with 14 TS2307 and 1 TS7006, matching the 15 recorded diagnostics.
    • Worker dry-run: exit 0 with an empty assets fixture. This is not a build of the full product.
    • Reference scheduler: the gate reported PASS in my run. I did not extract the 500/428 counts myself. The test writes an evidence/ directory at the repository root, which I removed.
    • Checksums: SHA256SUMS verifies. Both prior originals fetched from main match the captured hashes (c15eb0cc… and 5f6f3abc…).
    • Unchanged surfaces: wallet methods in source are still only eth_accounts, eth_requestAccounts and personal_sign. server/auth.ts, server/world-api.ts, worker/, public/_headers, migrations, wallet.ts, siwe.ts and the package files are unchanged against c4f451b.

    Not measured

    • The private 1528-test suite, private TypeScript/Vite build and the frozen f9 counterexample replays remain team claims. I compared against public parent c4f451b, not private f9.
    • The candidate is not deployed, so production match is a release gate, not something I checked.
    • The required 11-case matrix is covered by the team's fixed control

    • lowLOW-5/LOW-6 regression: overlapping /api/me/home reads each repeat the budgeted Alchemy index read (request-start now compared with a live-clock stamp)source/server/ownership.ts:267

      State: OPEN (regression vs public parent c4f451b). Blocker: yes for the LOW-5 closure claim "20 concurrent requests during held delta: one index reload" (it only holds with a frozen fixture clock); not a Critical/High/Medium, and not an authority failure: ownerOf proof is NOT repeated and no ownership is granted.

      Root cause: discovery/candidate cache freshness is evaluated with req.now (server/auth.ts:715 captures it at route entry, before readSession, the 'home' limiter and the roster read), but the stamps it is compared with are taken from the LIVE clock later (attemptedAt at ownership.ts:247, Indexed.at at :252, both req.clock() after the budget await). Since R8 isFreshAge rejects negative age (src/shared/freshness.ts:5-6), a request that entered the route before another request's index read began sees age<0 and treats that brand-new discovery as not fresh. proof() serialises same-address requests (ownership.ts:228) and each queued request re-runs discovery with its own older req.now, so every queued request fails keep() at :256 and :267-268 and performs its own budget() call plus a full keyed getNFTsForOwner read (up to 5 pages). With the budget refusing, each queued request re-asks the chain:index limiter and, for a wallet with no counting seat, the lane (D1 INDEX_LANE_READY/probe reservation) instead of reusing the 30 s refused-discovery backoff.

      Reachability: ordinary. Any two same-address home reads that overlap in one isolate (N tabs reacting to the 'signed-in' BroadcastChannel hint each send /api/me/home?fresh=1; a script can send 20 with one session cookie, the 'home' bucket allows 20/min per session). One burst from one session spends the whole per-location chain:index budget (documented 20/min), turning other owners' due index reads into 'limited' for that minute; it can be repeated each minute.

      Fix direction (behaviour-preserving): judge discovery/candidate freshness with the same clock domain as the stamps (req.clock?.()??req.now read after the proofing queue wait, as proofNow already does at :273), or stamp attemptedAt/at so that a waiter that queued behind the load cannot see them as future.

      Counts measured (reproduced fact): candidate 20 budget calls / 20 index reads / 1 eth_call for 20 overlapping reads; parent c4f451b with the identical probe: 1 / 1 / 1. Refused budget: candidate 20 budget calls + 20 lane calls, parent 1 budget call + 20 lane calls. Team claim (OWNERSHIP_FRESHNESS.md "20 concurrent requests during held delta: One index reload") is measured only with clock()===now. Unmeasured: real Workers limiter/isolate fan-out.

      Probe (node --test, placed in source/tmp/, imports ../server/ownership.ts): gateway roster owners[7]=A; index fetch returns tokenId 7; request object built exactly like server/auth.ts:770: {now: clockAtCall, clock: ()=>liveClock, budget: async()=>{budget++; await 2ms; liveClock+=20; return true}}. Fire 20 ownership.home(A, req, false) without awaiting, liveClock+=1 between calls, then await all.

      Expected (and parent c4f451b actual): budget=1, getNFTsForOwner=1, eth_call=1.

      Actual at 7215c5d: budget=20, getNFTsForOwner=20, eth_call=1; every answer complete (no recheck).

      Same with budget returning false and fresh=true: expected budget=1 (30 s refused backoff, as the sequential x20 control asserts); actual budget=20, lane=20, all 'limited'.

      Failing state: request R2 with req.now=T+1 queued behind R1 whose index read began at clock T+20 -> isFreshAge(T+1, T+20, ttl)=false -> reload.

    • lowLOW-1 over-correction: an idle provider change (including a late EIP-6963 announcement with no user action, or a wallet holding the same account) now revokes the accepted displayed sessionsource/src/world/auth.ts:287

      State: POLICY DECISION / partial (behaviour change vs public parent c4f451b, where providerChanged cleaned up only for an active flow: "if(activeFlow)this.automaticCleanup(...)"). Blocker: yes until the requester confirms it as intended, because it matches the brief's blocker class "unintended session [revocation]" for the no-user-action variant; no authority is gained (the request carries the browser's own live cookie and the server gate is unchanged), so severity is Low.

      Function: AuthClient.providerChanged() now calls automaticCleanup('provider-switch',...) unconditionally, and planCleanup (authCleanup.ts:20) returns displayed-session for every non-stop reason whenever a session is displayed. There is no click, no pending challenge and no verify owner in this state: the only thing "cleaned" is a fully accepted, idle session.

      Why it is wider than the prior Low #1 (which was about a switch while the click that produced PRESENT is still live):

      1. No user action: WalletRegistry.current() changes when a second extension announces itself late (options 1 -> 2 with no remembered choice makes chosen null, wallet.ts compute()), which fires onProviderChange. A page that restored a valid cookie session is signed out server-side just because another wallet extension injected after the session read.
      2. Same account: picking another wallet that exposes the very address of the session also revokes it, whereas accountChanged to the session's own address is a no-op (auth.ts:531).
      3. Related state on the account path (auth.ts:537): session A displayed, wallet on B, click in preflight, wallet returns to A -> held session A is revoked by expectedAddress although the resulting context matches the session (reproduced; parent comparison unavailable because the parent has no click-specific preflight read to hold). The automatic provider-switch logout is also not broadcast (broadcast=false), so sibling tabs keep showing the revoked session until their next read. The method comment at auth.ts:278-281 still describes the old contract ("an address other than the session's shows as a mismatch"), and the pre-R8 test asserted 'mismatch'; it was edited to expect revocation.

      Counts per run: prompts 0, challenge 0, verify 0, cleanup POST 1 (expectedAddress, 204, Set-Cookie clear), hints 0, RPC 0. Rows: sessions created 1 / live 0 / revoked 1; challenges 1 used / 0 pending / 0 invalidated. Cookie alias: the single browser jar cookie for session #1 is cleared.

      Fix direction (keeps the R8 switch-during-live-click cleanup): gate the provider-switch displayed-session plan on there being a cancelled click/owner for this event (as the parent's activeFlow did, plus the released-owner case prior Low #1 needed), or first read the new provider's eth_accounts and only clean when it names a different address; treat a transition to "no provider chosen" as a lock-like event that preserves the accepted session.

      Inference (not measured): real extension announce timing; Team claim: AUTH_STATE_MACHINE.md matrix row "account/provider switch | present | displayed expectedAddress".

      Setup (reviewer measurement, offline): npm ci --ignore-scripts in source/ (Node v24.21.0); parent = git archive c4f451b source in a scratch dir sharing node_modules. Probe file in source/tmp/ imports tests/auth-r7-fixtures.mjs (real AuthClient + real Worker handlers + migrations over node:sqlite; synthetic keys/provider/cookies/clock) and src/world/wallet.ts; run node --test tmp/auth1.test.mjs (parent: AUTH_R7_SOURCE=. in the parent tree).

      P1 (late announcement): browser b signs in as A through the Worker (session #1 live). WalletRegistry over a fake window; announce provider p(A) as com.alpha; tab uses getProvider=()=>registry.current() and notifies on registry change; wait until session displayed and idle. Then announce a second provider p2 as io.beta (no pick, no click). Event order: START -> GET session PRESENT(A) -> GET home -> announceProvider(#2) -> providerChanged(null) -> POST /api/auth/logout {expectedAddress:A} 204.

      Expected (and parent c4f451b actual): 0 logout requests; sessions created 1 / live 1 / revoked 0; GET /api/auth/session signedIn:true; client keeps session, account null.

      Actual at 7215c5d: 1 logout (address assertion, 204); sessions created 1 / live 0 / revoked 1; GET /api/auth/session signedIn:false; client session null, ended 'revoked'; prompts 0.

      P2 (same account): same start, getProvider switches to a second provider that returns the same address A, notifyProvider(). Parent: live 1, 0 logouts, session kept. Candidate: live 0 / revoked 1, 1 logout {expectedAddress}, signedIn:false.

      P5 (account path): session A live, provider on B, hold the click's own GET /api/auth/session, signIn(), then provider.switchTo(A), release. Candidate: 1 logout {expectedAddress:A} 204, live 0 / revoked 1, prompts 0, wallet now on A with no session.

    • lowINFO-1 partial: after a wallet lock keeps an unresolved verify owner (first reconciliation 503), unlocking the SAME account auto-revokes the committed session by noncesource/src/world/auth.ts:533

      State: PARTIAL (improved vs parent, which invalidated at the lock itself). Blocker: no if the requester accepts "any later accountsChanged supersedes lock" as policy; otherwise yes under "LOCK ... never auto-revokes accepted session". Severity Low: the user's own committed session and signature are lost without an explicit action; no cross-account authority.

      Function: accountChanged(a). For a!==null it treats every event with a retained owner as a context switch: cancelOwners('context-switch') overwrites the owner's 'lock-reconcile' disposition (authLifecycle.abandon rewrites cancellationReason), and planCleanup('account-switch') with no displayed session returns verify-owner, so revokeAbandoned posts {expectedNonce} with the live cookie the verify installed. It never checks whether a equals the owner's own account (owner.account) or the account that was locked.

      Reachable state: lock while verify is in flight -> verify commits (row live, Set-Cookie applied) -> the single reconciliation read fails (503/429/malformed/network). Nothing schedules another read (reconcileLockedOwner clears owner.reconciling and returns), so the owner stays RETAINED/lock-reconcile for as long as the tab is idle; the wallet-visible account is null, so the natural next user action is to unlock the wallet, which emits accountsChanged([A]) and triggers the revoke before any canonical read can release the owner. The brief's control "lock-503 then later valid canonical receipt must release lock owner before stop" only holds when a read happens first; unlock comes first in practice.

      Counts: prompts 1, challenge 1, verify 1 (200, committed), reconciliation GET 1 (503), cleanup POST 1 (expectedNonce, 204, clears cookie), hints 0, RPC 0. Rows before unlock: sessions created 1 / live 1 / revoked 0, challenge used 1, GET /api/auth/session signedIn:true, owner RETAINED reason lock-reconcile. After unlock: live 0 / revoked 1, signedIn:false, owner CONSUMED reason context-switch, client session null.

      Fix direction: when a equals the retained lock-reconcile owner's account (same provider), keep the reconciliation-only disposition and start the canonical read (reconcileLockedOwner) instead of abandoning it as a context switch; only a different address is a switch. Optionally retry the reconciliation read on a bounded timer/visibility so the owner does not sit unresolved.

      Unmeasured: real wallet lock/unlock event shapes (some wallets emit [] then [A] on every unlock, some only on lock).

      Setup (reviewer measurement, offline): npm ci --ignore-scripts in source/ (Node v24.21.0); parent = git archive c4f451b source in a scratch dir sharing node_modules. Probe file in source/tmp/ imports tests/auth-r7-fixtures.mjs (real AuthClient + real Worker handlers + migrations over node:sqlite; synthetic keys/provider/cookies/clock) and src/world/wallet.ts; run node --test tmp/auth1.test.mjs (parent: AUTH_R7_SOURCE=. in the parent tree).

      P4: tab with provider(A); beforeSend holds POST /api/auth/verify; intercept returns 503 for GET /api/auth/session once 'bad' is set. await ready; flow=signIn(); wait until verify is held; p.switchTo(null) (lock); bad=true; release verify; await flow. Mid-state measured: sessions live 1, canonical GET /api/auth/session (direct browser read) signedIn:true, lifecycle cleanup status RETAINED. Then bad=false; p.switchTo(A) (unlock, same account); wait.

      Expected (INFO-1: preserve the committed session; a valid post-fence read releases the owner): 0 logout requests, sessions live 1, signedIn:true, owner RELEASED.

      Actual at 7215c5d: POST /api/auth/logout {expectedNonce} -> 204; sessions created 1 / live 0 / revoked 1; signedIn:false; owner CONSUMED with cancellationReason 'context-switch'; prompts 1 (the signature is wasted).

      Baseline control (parent c4f451b, same probe): the lock itself already sent the nonce logout (challenge invalidated 1, sessions created 0), so the candidate is better at the lock event but still revokes at the unlock event.

      Variant P3 (lock then unlock A before the verify response): candidate and parent both send {expectedNonce} with the flow cookie, challenge invalidated, verify refused, sessions created 0, prompts 1.

    • lowLOW-2 side effect (regression vs parent): any sibling-tab hint read while the wallet prompt is open makes the client silently discard the valid signature; the same sign-in needs a second personal_signsource/src/world/auth.ts:442

      State: OPEN (new in R8 v1.1; parent c4f451b completes the sign-in on the same event order). Blocker: no for authority (fails closed, no session is created); it is listed because the brief treats unintended prompts as a blocker class and here one user intent ends up needing two wallet signatures, with no notice explaining the first was dropped. Severity Low.

      Function: AuthClient.signIn(), post-signature gate canSign() (auth.ts:421) = live() && hasAbsentPreflight(click) && click.preflight.readSeq===this.sessionReads. The channel listener (auth.ts:257) calls restore() for every message without regard to a busy click (visible() does check !this.busy, auth.ts:181). That ordinary read increments sessionReads, so after the prompt returns readSeq no longer matches even when the newer canonical answer is the same ABSENT (lifecycle.know(ABSENT) keeps the receipt; only the sequence comparison fails). The pre-flight stage has a one-shot re-read for exactly this overtaking case (auth.ts:386-389), the post-challenge and post-signature gates do not: line 442 ends the click with phase idle and notice null (sessionUnknown() is false because knowledge is ABSENT), the signed challenge is never verified and stays pending until its server deadline.

      Security reasoning: the superseding read is canonical, valid, newer than the click's receipt and says ABSENT, so proceeding to verify would be at least as well-founded as the original receipt; discarding gains nothing and costs a second prompt. If the newer read says PRESENT/UNKNOWN the existing knowledge check already blocks.

      Trigger: any BroadcastChannel message from a same-origin tab while the prompt is open (a sibling's signed-out after its own logout or switch, or a signed-in hint for a session that was already revoked/cleared again). Wallet prompts stay open for seconds to minutes, so the window is wide.

      Counts (candidate): prompts 1, challenge 1, verify 0, cleanup 0, hints received 1, session GETs: click preflight + 1 hint read; rows: sessions created 0; challenges 1: used 0 / pending 1 / invalidated 0; no cookie; client phase idle, sessionKnown true, session null, notice null. Parent: prompts 1, verify 1 (200), sessions created 1 / live 1, challenge used 1.

      Fix direction: mirror the pre-flight rule after the prompt: when the receipt was overtaken by a read whose knowledge is valid ABSENT, either accept that newer ABSENT as the click's receipt (it is causally later) or perform the one per-click re-read before verify; if the click must still end, set a notice (e.g. session-unknown/challenge-lost) so the discarded signature is not silent.

      Setup (reviewer measurement, offline): npm ci --ignore-scripts in source/, Node v24.21.0; parent = git archive c4f451b source. Probe in source/tmp/ using tests/auth-r7-fixtures.mjs (real AuthClient + real Worker + node:sqlite).

      Steps: w=setup(); A=newAccount(); p=provider(A,{beforePrompt: hold}); q=tab(w,b,p); await ready(q); flow=q.signIn(); wait until personal_sign is open; q.channels.at(-1).message() (sibling hint; canonical state is still signed out); flush; release the prompt (valid signature returned); await flow.

      Event order: SIGN_CLICK -> GET session ABSENT (click receipt, readSeq n) -> POST challenge 200 -> personal_sign opened -> CHANNEL_MESSAGE -> GET session ABSENT (readSeq n+1) -> signature returned -> canSign() false -> click ends.

      Expected (parent c4f451b actual): POST /api/auth/verify 200, sessions created 1 / live 1, client signed in, prompts 1.

      Actual at 7215c5d: no verify request; sessions created 0; challenge pending 1; phase 'idle', notice null; prompts 1 spent; a second click issues a new challenge and a second personal_sign.

    The findings file is in place at the repository root with three substantiated findings, and the working tree holds no other changes. Here is the review.

    Outcome

    No blocker found. The R8 v1.1 candidate holds its Auth and ownership invariants in everything I could execute, but it introduces two Low regressions and one documented-policy inconsistency, all reproduced offline. The candidate is not deployed, so production parity remains an unmeasured release gate.

    Findings (all in .imd-findings.json)

    • Low, regression. A passive change of wallet-provider identity now revokes a valid session. Since R8 v1.1, providerChanged in the client auth module sends a displayed-address logout whenever deps.provider() returns a different object. The wallet registry changes that object without any player pick: window.ethereum to the first late EIP-6963 announcement, or one auto-chosen wallet to none when a second wallet announces. Reproduced with the repository's own Worker and SQLite fixtures: restored session, no click, late announcement, then one logout 204, live rows 0, revoked 1, canonical signed out. The same script on the R7 tree sends nothing and keeps the session. Fails safe, so not a blocker, but affected players are logged out on every page load.
    • Low, regression. A good world snapshot whose Worker-side stamp is ahead of the browser clock is classified as a failed read. The poller then uses the failure ladder and settles at a 120-second cadence for the whole session instead of 15 minutes, while valid data is on screen. Verified with the exported functions; the R7 version returned a success value for the same input.
    • Info, pre-existing. The gateway's shared-copy warm accepts a record dated up to 60 seconds in the future and rewrites its stamp to now, which contradicts the frozen rule against re-dating remote future timestamps. Bounded to inter-isolate skew; roster data only names candidates.

    Fixed matrix and controls

    All eleven required cases, the same-address old/new nonce control and the lock-503-then-valid control have executable public tests that pass under my run. Ownership controls for fresh=1 refused x20 (1 RPC), proof at 31 s plus fresh at 32 s (2 RPCs), failed-delta cap consumption, sold-seat at 29999/30000/30001 ms, backward and non-finite clocks, and future D1 dates all pass. Market and floor boundaries reject non-finite and negative operands and products while keeping finite negative changes.

    Not measured

    Production deployment, Cloudflare bindings and WAF, real OS wallets and browsers, cross-isolate RPC totals, and the share of real clients with late-announcing wallets or negative clock skew. This is a limited offline review, not a certification.

    • lowR8 v1.1 regression: a passive wallet-provider identity change (late EIP-6963 announcement, no click, no pick) revokes a valid restored sessionsource/src/world/auth.ts:287

      State: fixed-for-user-pick / open-for-passive-change.

      Blocker: no (fails safe: the session is revoked, no prompt, no new session; availability regression only). R8 v1.1 changed providerChanged() so that ANY change of deps.provider() identity while a session is displayed selects planCleanup('provider-switch', {displayedAddress}) = displayed-session and POSTs /api/auth/logout {expectedAddress}, which the server honours (live cookie + matching address -> revoked_at set, Set-Cookie clear).

      On R7 (c4f451b, auth.ts:250-258) the same event with no active flow sent nothing and kept the session (mismatch display only).

      The policy matrix (AUTH_STATE_MACHINE.md 'account/provider switch | present | any | any | displayed expectedAddress') assumes a provider switch is the player's pick, but WalletRegistry.current() (src/world/wallet.ts:65-70, compute() :77-84) also changes object identity without any pick: (a) window.ethereum is current while no EIP-6963 wallet has announced, then the first announcement arrives and is auto-chosen (options.length===1, no remembered rdns), so current() becomes a different provider object; (b) one wallet is auto-chosen, a second wallet announces later with no remembered choice, so chosen becomes null and current() becomes null (needsChoice).

      Both fire registry.subscribe -> providerChanged -> p!==this.bound -> cleanup. A wallet whose announcement lands after the page's restore() GET /api/auth/session has completed (an asynchronously announcing extension or in-app browser, or a second extension installed after the last pick) therefore logs the player out on every page load; the 'signed-out' broadcast also ends sibling tabs.

      Reproduced facts: candidate probe below gives live 0 / revoked 1 / one logout {expectedAddress} 204 / canonical signedIn:false / cleanupPlans [{reason:'provider-switch',kind:'displayed-session'}] with prompts 0 and no SIGN_CLICK event; the identical probe on the R7 tree (git archive c4f451b) sends no logout and keeps live 1.

      Team claim separated: auth-r8 R8-1 'malformed-provider' and wallet-client 'choosing another cleans displayed session' cover an explicit pick or a switch during a click; no public test covers a provider-object change with no pick and no click.

      Inference: production share of late-announcing wallets is unmeasured. Fix that preserves the intended design: treat only a registry pick (WalletRegistry.choose) or an account change as a switch with cleanup authority; a passive current() change (auto-choice, window.ethereum -> announced object, 1 -> 2 announcements) should rebind and show mismatch/needsChoice without revoking, or the registry should keep the originally bound object current until the player picks.

      From source/ with dependencies installed, using only the repository's own offline fixtures (tests/auth-r7-fixtures.mjs real Worker + node:sqlite, test-only keys):

      import assert from 'node:assert/strict';

      import {setup,newAccount,provider,tab,ready,until,flush,rows,prompts,logouts} from './tests/auth-r7-fixtures.mjs';

      import {WalletRegistry} from './src/world/wallet.ts';

      const w=setup(),A=newAccount(),b=w.browser();

      assert.equal((await b.signIn(A)).verify.status,200); // browser already holds a live session cookie

      const injected=provider(A),announcedWallet=provider(A); // same account, different provider objects

      const listeners=new Map();

      const win={ethereum:injected,addEventListener:(t,f)=>listeners.set(t,f),removeEventListener:()=>{},dispatchEvent:()=>true};

      const registry=new WalletRegistry(win,null);registry.start(); // nothing announced yet: current()===window.ethereum

      const q=tab(w,b,injected,{getProvider:()=>registry.current()});registry.subscribe(()=>q.notifyProvider());

      await ready(q);assert.equal(q.c.state.session?.address,A.address.toLowerCase()); // restored PRESENT, no click

      // late EIP-6963 announcement, no pick:

      listeners.get('eip6963:announceProvider')({detail:{info:{uuid:'u1',name:'Wallet',rdns:'io.example.wallet',icon:null},provider:announcedWallet}});

      await until(()=>logouts(q).length>0&&logouts(q).every(e=>e.finished));await flush();

      console.log(rows(w).counts,logouts(q).map(e=>({addr:e.addressAssertion,status:e.status})),q.c.state.session,await (await b.get('/api/auth/session')).json(),prompts([injected,announcedWallet]));

      Expected (R7 baseline c4f451b, same script: no logout request is sent, counts.live stays 1, canonical signedIn:true): a passive provider-object change with no click and no pick preserves the accepted session. Actual on 7215c5d/8a22b51: counts {created:1, live:0, revoked:1}, one POST /api/auth/logout with expectedAddress -> 204, client session null, canonical {signedIn:false}, prompts 0, lifecycleSnapshot.cleanupPlans=[{eventId:1,reason:'provider-switch',kind:'displayed-session'}]. Variant (b): announce wallet One first (auto-chosen), sign in, then announce wallet Two with no remembered rdns -> registry.current()===null, needsChoice:true, and the same displayed-session logout revokes the session (live 0, revoked 1).

    • lowR8 v1.1 regression: a good world snapshot whose server fetchedAt is ahead of the client clock is classified as a failed read, so a client with a slightly slow clock polls at the 2-minute failure cadensource/src/world/cadence.ts:62

      State: policy decision with an unmeasured side effect; open.

      Blocker: no (load/UX, not authority). worldReadResult() compares the Worker's epoch fetchedAt (server/gateway.ts:212 fetchedAt=this.now()-ageMs, i.e. Cloudflare's clock) with the browser's Date.now(). isFreshAge requires age>=0, so a client whose wall clock is behind the server by more than (network latency + Age) sees every fresh swarm/workers sample as 'future' and worldReadResult returns false, the same value as a transport failure. startPoll() (cadence.ts:98-103) then increments failures and schedules nextDelay(false,...): 5 s, 15 s, 30 s, 60 s, then 120 s for ever, instead of REFRESH_MS=900 s after a good read, i.e. 7.5x the steady-state /api/world/snapshot request rate from that client for the whole session, while the data it just received is valid and is displayed.

      Before R8 (c4f451b cadence.ts:59) a future stamp counted as a good read. FRESHNESS_BOUNDARIES.md records the intent ('invalid/future source fetchedAt cannot count as a good read') and freshness-v11.test.mjs:61-65 pins it, but neither considers that 'not good' is mapped onto the failure retry ladder rather than onto 'behind' (one bounded follow-up) or onto a plain success-for-scheduling.

      Clock skew of a few seconds on consumer devices is routine (the SIWE check in siwe.ts allows 10 minutes of skew for exactly this reason). The same root cause makes marketView() (market.ts:112) label a Worker-fallback quote 'stale' (weather 'unknown', floor hidden) for the same skewed client; that path is secondary because the direct DEX Screener read stamps with the client's own clock.

      Reproduced fact: the probe below.

      Not measured: the share of real clients with negative skew; WorldApp.tsx (withheld) is assumed to feed worldReadResult into startPoll as the public fixture comments describe.

      Suggested fix preserving the policy: keep refusing to label a future-dated sample fresh, but return 'behind' (or true) for the scheduler when the samples are fresh and the only defect is a bounded negative age (e.g. up to FOLLOW_UP_MS or the SIWE skew allowance), so a skewed client gets one follow-up read, not the failure ladder.

      node --experimental-strip-types -e "

      import('./src/world/cadence.ts').then(({worldReadResult,nextDelay,FIRST_RETRY_MS,REFRESH_MS})=>{

      const now=1_000_000,s=at=>({state:'fresh',data:{seats:{}},url:'x',fetchedAt:at});

      console.log(worldReadResult({swarm:s(now+1),workers:s(now)},now)); // client 1 ms behind the Worker clock

      console.log(worldReadResult({swarm:s(now),workers:s(now)},now)); // control

      console.log([1,2,3,4,5,6].map(n=>nextDelay(false,n,FIRST_RETRY_MS)),REFRESH_MS);

      });" (run from source/)

      Expected: a fresh snapshot the Worker dated 1 ms ahead of this browser's clock is still a successful read for scheduling (true or 'behind'), so the next poll is REFRESH_MS=900000 or one FOLLOW_UP_MS follow-up. Actual: first line prints false (identical to a transport failure), control prints true, and the delays a client with a persistently slow clock gets are [5000,15000,30000,60000,120000,120000] versus 900000 after a good read, i.e. a permanent 120 s poll (7.5x request rate) while valid data is on screen. R7 control: git show c4f451b:source/src/world/cadence.ts line 59 returns 'behind'/true for the same input.

    • infoGateway shared-copy warm accepts a record dated up to 60 s in the future and rewrites its fetchedAt to now, contrary to the frozen freshness policy's 'never rewrite a future stamp as now'source/server/gateway.ts:256

      State: accepted limit / unchanged since f9 (gateway.ts is not in the R8 change set), reported because the task's freshness controls require rejecting remote future timestamps without rewriting them as now and FRESHNESS_BOUNDARIES.md states 'never synthesize a future stamp'.

      Blocker: no. ReadGateway.warm() (gateway.ts:253-259) seeds a cold isolate from the per-colo Cache API copy written by another isolate.

      It tolerates age>=-60_000 (a record dated up to one minute ahead of this isolate's clock) and then stores fetchedAt=Math.min(record.fetchedAt,at), i.e. a future-dated record is re-stamped as read 'now', with validUntil=max(entry.validUntil, now+ttl) giving it a full UPSTREAM_TTL_MS (5 min) from this isolate's clock and labelling it 'fresh' to clients and to the ownership roster read (Ownership.world() uses gateway.source('swarm'), whose cache entry this warm may have seeded).

      Impact is bounded: the writer is another Worker isolate in the same Cloudflare location, so the skew is Cloudflare's own inter-isolate clock skew, and the roster only names candidates (ownerOf still proves them). It is a documented-policy inconsistency rather than an authority defect, and exact-boundary behaviour (age === -60_000 accepted) is untested.

      Reproduced fact: the probe below. Suggested fix if the policy is to be uniform: either reject age<0 like isFreshAge does elsewhere, or keep the record's own fetchedAt unmodified (and let label()/servable() judge it) instead of re-dating it.

      From source/ (offline, injected fetch and clock):

      import {ReadGateway,SHARED_SHAPE} from './server/gateway.ts';

      let t=1_000_000;const g=new ReadGateway(async()=>new Response(JSON.stringify({seats:{},owners:[]}),{status:200}),()=>t,{sharedWaitMs:50});

      const shared={async get(k){return {v:1,shape:SHARED_SHAPE,key:k,data:{seats:{},owners:[],at:1},fetchedAt:t+59_000};},async put(){}};

      const snap=await g.snapshot(undefined,shared);

      console.log(snap.sources.swarm.state,snap.sources.swarm.fetchedAt,t);

      Expected under the stated policy: a shared record dated 59 s in the future is not usable as current data (ignored, or kept with its own future fetchedAt so downstream freshness gates reject it). Actual: prints fresh 1000000 1000000, i.e. the future record is accepted and its fetchedAt is rewritten to this isolate's now, and no upstream read is made within the next 5 minutes.

    #1844Audit economicsClaude2 findings · 1 low

    The review is complete. Findings are written to .imd-findings.json and the tree is otherwise unchanged (my scratch tests and the test-generated evidence/ directory were removed).

    Verdict on closure. No blocker found within scope. I found no Critical/High/Medium issue, no Auth or ownership invariant failure, no unintended prompt or session, no old-flow cross-revoke, no unbounded keyed RPC, and no wallet-method or header expansion. The unmeasured deployment of commit 8a22b51 remains the release gate, and nothing here certifies the live baseline. This is a limited offline review, not a certification.

    What I measured myself (Node v24.21.0, locked dependencies via npm ci):

    Full public globnot claimed641 tests, 637 pass, 4 fail

    The four full-glob failures are excluded inputs: three test files cannot load the withheld households.ts, and the deploy-evidence test fails on the limiter table because wrangler.jsonc is redacted in the public tree. The three shipped minimized counterexample traces and the candidate trace all pass on the candidate. I could not replay them against the private f9 parent, so the team's "f9 rejected" claim stays a team claim. The Worker dry-run was not rerun.

    Fixed 11-case matrix. Every row has an executable control that passed in my run, including the same-address old/new nonce control and the lock-503-then-valid-read control. Wallet methods in src/world/wallet.ts and src/world/auth.ts are still only eth_accounts, eth_requestAccounts, and the line-checked SIWE personal_sign. Server Auth, World API, headers, and lock files match the hashes the boundary check records.

    Findings:

    • Low, open, not a blocker. A /api/me/home request queued behind a failing ownership proof inherits that failure instead of running its own proof, contradicting the stated serialization policy. Fail-closed (503), so availability only. Reproduction and a one-line fix are in the findings file at source/server/ownership.ts:228.
    • Info, hygiene. The public scheduler test writes 19 artifact files above source/ into the review repository root, outside every published integrity receipt, at source/tests/auth-reference-scheduler.test.mjs:9.

    Residuals I accept as documented: GET is not a cross-tab lock, per-isolate caches are not a global RPC cap, late cookie clears and process death are best effort, and the Worker fetch has no bounded deadline. The provider-switch cleanup revoking the browser's shared session across tabs is a policy decision, not a defect.

    • lowOwnership request queued behind a failing proof inherits that failure instead of re-evaluating with its own proofsource/server/ownership.ts:228

      State: not fixed in R8 v1.1 (open).

      Blocker: no. It is fail-closed (503 OWNERSHIP_UNAVAILABLE, never an empty complete home), grants no authority and expands no method or header, so it is an availability defect, not an Auth/ownership invariant failure. Ownership.proof() serialises per-address updates by chaining a waiting caller on the in-flight update with pending.then(onFulfilled) only.

      When the in-flight update rejects (a first or expired-epoch proof whose Multicall3 ownerOf eth_call failed, or a proof that completed at/after its 30 s deadline), the rejection propagates through .then() to every caller queued behind it. The queued caller never runs its own update(): no ownerOf RPC is attempted for it even if the node has recovered, and its own captured roster and fresh intent are not re-evaluated.

      This contradicts OWNERSHIP_FRESHNESS.md line 20 ('A caller waiting behind another request re-evaluates its own captured roster and fresh intent; it does not blindly label another request's answer complete') and the stated availability design ('First/expired proof failures ... their retries remain unavailable and are bounded by existing request limiters'): the waiter is refused without any retry.

      Reproduced facts: with a held first RPC that fails and RPC healthy before the first failure is observed, the second request rejects with OWNERSHIP_UNAVAILABLE and the fixture counts 1 RPC in total; expected 2 (one failed, one successful for the waiter).

      Counts: index reads 1, ownerOf RPC 1, lane calls 0. The existing ownership-v11 controls only queue callers behind successful updates, so they cannot see this. Minimal fix that preserves the serialisation design: chain on settlement rather than fulfilment, e.g. return pending.then(()=>this.proof(...), ()=>this.proof(...)) (or pending.catch(()=>{}).then(()=>this.proof(...))), so the waiter performs its own epoch evaluation and proof after the predecessor settles.

      A re-run of the waiter still goes through the same budget/lane/limiter gates, so the bounded-RPC argument is unchanged.

      From the repository's source/ directory with locked dependencies installed (npm ci), save the following as tests/scratch/own-queue.test.mjs and run node --test tests/scratch/own-queue.test.mjs. Expected (per OWNERSHIP_FRESHNESS.md): the queued second request performs its own proof after the first settles, fixture RPC count 2, second request resolves. Actual on commit 7215c5d (private 8a22b51): the second request rejects with OWNERSHIP_UNAVAILABLE and RPC count stays 1 (console line 'second result: OWNERSHIP_UNAVAILABLE rpc calls: 1'); assertion 1 !== 2 fails.

    • infoPublic scheduler test writes evidence artifacts outside source/ into the review repository rootsource/tests/auth-reference-scheduler.test.mjs:9

      State: open (hygiene).

      Blocker: no. The recorded public filtered-subset command includes tests/auth-reference-scheduler.test.mjs, whose save() helper writes into resolve(import.meta.dirname,'../../evidence/reference-scheduler'), which resolves to /evidence/reference-scheduler, one level above the published source/ tree rather than inside it.

      A reviewer who runs the exact recorded command from source/ ends up with 19 untracked JSON files in the review repository root (fixed--.json, focused-.json, gate---RESULT.json and LATEST.json).

      Each file embeds provenance().sourceRoot, an absolute local path, and the gate file names contain a wall-clock timestamp and random UUID, so the artifacts are not byte-reproducible and are easy to commit by accident into a package whose manifests (submission7-r8closure-published-source.json, SHA256SUMS, BOUNDARY_CHECK.json) do not cover them.

      TEST_RESULTS.json's sourceUnchangedDuringRun receipt also only speaks for source/, so these writes are outside every published integrity receipt.

      Reproduced fact: after the recorded command, git status --short at the repository root shows ?? evidence/ with 19 files; the tree was otherwise unchanged.

      Minimal fix: write artifacts under a path inside source/ that .gitignore already excludes (for example tmp/evidence/reference-scheduler, since source/.gitignore ignores tmp/), or honour an explicit output environment variable and skip persistence when it is unset; record the artifact location in TEST_RESULTS.json if artifacts are meant to be part of the receipt.

    The findings file is written and every path, line and snippet checks against the tree. Final recap follows.

    Outcome. I kept 8 findings (6 Low, 2 Info) in .imd-findings.json, merged from the 13 specialist entries. Every kept finding was reproduced by me against the pinned tree with the repository's own offline fixtures (real AuthClient, real Worker handlers and migrations over node:sqlite, injected providers and clocks), and each was also run against the public parent c4f451b as a control. No Critical, High or Medium defect reproduced. The ninth specialist entry (verdict matrix) was bookkeeping, as the brief says.

    Findings, most severe first

    • Idle provider-registry change revokes an accepted session (auth.ts:287). A late EIP-6963 announcement, a second wallet announcing, or a same-account provider object change, with no click and no pick, sends a displayed-address logout that the Worker honours. Parent kept the session. Three specialists merged. Blocker only as a policy decision: the state-machine table says switch means revoke, the method's own comment says mismatch.
    • Overlapping home reads repeat the keyed index read (ownership.ts:256). Request-start now is compared with a live-clock stamp, so each queued same-address request re-spends the chain:index budget. Measured through the real Worker: a 20-request burst cost 21 index reads on the candidate and 2 on the parent. ownerOf stayed at one call, so no authority effect. Two specialists merged.
    • Lock then same-account unlock revokes the committed session by nonce (auth.ts:533). The candidate correctly preserves at lock, but the unlock event rewrites the lock-reconcile owner to context-switch. Parent revoked at lock, so this is partial closure of INFO-1. Two specialists merged.
    • Sibling-tab hint during an open prompt drops the valid signature (auth.ts:442). No verify, challenge left pending, no notice, second signature needed. Parent completed the sign-in.
    • Queued ownership caller inherits the predecessor's failure (ownership.ts:228). Pre-existing, identical on the parent, contradicts the freshness document's serialisation rule. Fail-closed.
    • Future-by-skew fetchedAt classified as a failed read (cadence.ts:62). A client clock behind the Worker lands on the 5 s to 120 s retry ladder instead of 15 minutes, and the market view hides weather and floor. Policy side effect, not authority.
    • Two Info items: gateway warm re-dates a future shared record to now, and the scheduler test writes 18 evidence files above source/ with an absolute local path embedded.

    • lowR8 v1.1 regression: any provider-registry change with no user pick and no click (late EIP-6963 announcement, second wallet announcing, same-account provider object) revokes the accepted displayed sesssource/src/world/auth.ts:287

      State: open / policy decision required. Blocker: yes until the requester confirms a pick-less registry change is a 'switch' (brief blocker class: unintended session revocation; no privilege gain, so severity Low). Merged from three specialist findings (audit_math b0d5473d, audit_permissions 96cfb0e8, audit_flow 4a612ae0); all three reproduce on the candidate and none on the public parent c4f451b.

      Mechanism (reproduced): providerChanged() now unconditionally bumps gen, clears account/sessionKnown/home and calls automaticCleanup('provider-switch', ..., held). planCleanup (authCleanup.ts:22) returns displayed-session whenever a session is displayed, so POST /api/auth/logout {expectedAddress:} is sent with the live cookie and the Worker revokes the row (204, Set-Cookie clear). This runs (a) with no click and no retained owner (idle PRESENT_ACCEPTED), (b) before the new provider's eth_accounts is read, so also when the new provider holds the session's own account, and (c) when WalletRegistry.current() merely becomes null. WalletPanel.tsx:21 wires onProviderChange to registry.subscribe, and wallet.ts compute()/current() change identity without any pick: window.ethereum -> first announced provider (options.length===1, nothing remembered), or one auto-chosen wallet -> null when a second wallet announces (needsChoice). A returning signed-in visitor whose extension announces after GET /api/auth/session restored the session is therefore signed out on every page load (ended:'revoked'). The parent (c4f451b auth.ts providerChanged) only cleaned up when a flow was active ('if(activeFlow)this.automaticCleanup(...)') and otherwise kept the session as mismatch/account-less. The method's own doc comment (auth.ts:278-281, 'an address other than the session's shows as a mismatch, so owner mode ends until that address signs in') still describes the parent contract, while AUTH_STATE_MACHINE.md row 'account/provider switch | present | any | any | displayed expectedAddress' describes the new one; the account path is asymmetric (accountChanged to the session's own address is a no-op, auth.ts:526).

      Counts per run (candidate): prompts 0, challenge 0, verify 0, cleanup POST 1 (expectedAddress, 204), hints 0, RPC 0. Rows: sessions created 1 / live 0 / revoked 1; challenges used 1 / pending 0 / invalidated 0. Cookie alias: the browser's single session cookie is cleared. cleanupPlans=[{eventId:1,reason:'provider-switch',kind:'displayed-session'}]. Event order P1: WALLET_eth_accounts -> START -> GET /api/auth/session PRESENT(A) -> GET /api/me/home -> eip6963:announceProvider (no pick) -> PROVIDER_SWITCH -> POST /api/auth/logout {expectedAddress:A} 204.

      Separation: reproduced facts = the rows/requests above on candidate and parent with one probe. Team claim (R8_FINAL_CLOSURE LOW-1: 'Account/provider context change still selects the displayed address') is confirmed as implemented; auth-r8 'malformed-provider' and wallet-client controls cover an explicit pick or a switch during a click only, no public test covers a provider-object change with no pick and no click. Inference: real share of late-announcing extensions (unmeasured, injected provider only). Fix preserving the R8 planner: treat only a registry pick (WalletRegistry.choose) or an account change as a switch with cleanup authority; on a passive current() change with no click and no RETAINED owner rebind, drop account and let the new provider's eth_accounts decide (same address: nothing; other: existing mismatch/account-switch path); treat a transition to 'no provider chosen' like a lock (preserve accepted session).

      Variant P1b: announce wallet One first (auto-chosen), tab over registry.current(), then announce wallet Two with nothing remembered -> registry.current()===null, needsChoice true. Variant P2: tab with getProvider:()=>chosen, q.signIn() once, then chosen=provider(A) (same account) and q.notifyProvider().

      Expected (parent c4f451b, same probe, measured): no logout request; sessions created 1 / live 1 / revoked 0; GET /api/auth/session signedIn:true; client session kept; prompts 0 (P2: 1, no new prompt).

      Actual at 7215c5d (measured, all three variants): one POST /api/auth/logout with expectedAddress -> 204; sessions created 1 / live 0 / revoked 1; GET /api/auth/session {signedIn:false}; client session null, ended 'revoked'; prompts unchanged; cleanupPlans [{eventId:1,reason:'provider-switch',kind:'displayed-session'}].

    • lowLOW-5/LOW-6 regression: overlapping /api/me/home reads for one address each repeat the budgeted keyed Alchemy index read (request-start now compared with a live-clock stamp)source/server/ownership.ts:256

      State: open (regression vs public parent c4f451b). Blocker: yes for the LOW-5 closure claim '20 concurrent requests during held delta: one index reload' (it holds only with a frozen fixture clock); not Critical/High/Medium and not an authority failure: the ownerOf epoch holds (1 eth_call) and no ownership is granted; the repeat is bounded by the chain:index budget (20/min per location), so it is not an unbounded keyed RPC. Merged from audit_permissions 7910a647 and audit_flow 69b7ba79.

      Mechanism (reproduced): server/auth.ts:715 captures now at route entry (before readSession, the 'home' limiter and the roster read) and passes it as req.now; req.clock is the live clock (auth.ts:770). In Ownership.proof the index answer is stamped at=req.clock() (ownership.ts:252) and the refused/failed attempt at attemptedAt=req.clock() (:247), but freshness of the candidates cache is judged with the request-start clock: keep at :256 (isFreshAge(req.now,v.at,...)) and discovery keep at :267-268 (isFreshAge(req.now,d.attemptedAt|d.indexed.at,...)). Since R8 isFreshAge rejects negative age (src/shared/freshness.ts:6). R8 also queues same-address callers behind the in-flight update and re-runs proof for each (:228). A queued request whose req.now precedes the stamp the previous request just wrote sees age<0, treats the seconds-old answer as not fresh, calls budget() again and performs its own keyed getNFTsForOwner read (up to 5 pages), stamping an even later at, so the next queued request fails the same way. Any positive Worker latency between route entry and the index read suffices; requests only need to overlap (N tabs reacting to one 'signed-in' hint, a script sending 20 with one cookie: the 'home' bucket allows 20/min per session).

      Impact: the documented discovery cadence (index once per 5 min per address, 30 s with fresh=1: OWNERSHIP_FRESHNESS.md, ownership.ts:21-24) does not hold under overlap; one session can spend the whole per-location chain:index budget each minute, turning other owners' due index reads into recheck:'limited' answers. In the refused-budget case the budget is consulted once per overlapping request in both parent and candidate (not a regression), while the candidate keeps ownerOf at 1 where the parent re-proved 20 times (an improvement).

      Counts (reproduced): direct Ownership class, 20 overlapping home() with req.now=START+i and a live clock that advances in budget()/index/rpc: candidate fresh=false {budget:20,indexReads:20,ownerOfRpc:1}, fresh=true {budget:20,indexReads:20,ownerOfRpc:1}; parent c4f451b same probe {1,1,1}/{1,1,1}. Real Worker + SQLite (tests/wallet-harness.mjs, counting CHAIN_LIMITER keys and fake-Alchemy calls, limiter/chain fetch advance the injected clock): candidate after a 20-request burst index 21 / budget 21 / eth_call 2 vs parent index 2 / budget 2 / eth_call 2; all 20 answers 200 and complete. Refused budget with 5 ms roster latency: candidate budget 20 / rpc 1, parent budget 20 / rpc 20.

      Separation: reproduced = the counts above. Team claim (OWNERSHIP_FRESHNESS.md '20 concurrent requests during held delta: One index reload'; ownership-v11 'twenty refused fresh reads') is measured only with clock()===now and strictly sequential reads, so it cannot see this. Unmeasured: production Cloudflare limiter/Alchemy quota effect (no production requests made). Fix preserving the design: judge candidate/discovery freshness in the same clock domain as the stamps (req.clock?.()??req.now read after the proofing queue wait, as proofNow at :273 already does), or let a queued caller reuse an index answer whose stamp is >= its own req.now (an answer read after the request began is not stale for it); keep rejecting future stamps only for remote/D1-supplied dates. Add a concurrent control (20 overlapping home(), now<clock) asserting budget==1, indexPages==1.

    • lowINFO-1 partially closed: a wallet lock keeps the uncertain committed verify owner, but the wallet's unlock of the SAME account then converts it to a context switch and auto-revokes the committed sessisource/src/world/auth.ts:533

      State: partial (INFO-1). Improved vs the parent, which revoked at the lock itself; the same revocation is now deferred to the unlock. Blocker: yes for the INFO-1 closure claim as written ('LOCK reconciles uncertain verify, never auto-revokes accepted session') unless the requester accepts 'any later accountsChanged supersedes lock' as policy; no cross-account authority and no confidentiality impact (the user's own just-committed session is revoked and a second signature is required), so severity Low. Merged from audit_permissions e70a8e2d and audit_flow c1046328.

      Mechanism (reproduced with the real AuthClient + Worker + SQLite fixtures): accountChanged(null) marks the retained verify owner 'lock-reconcile' and plans 'reconcile' (no logout). While that owner is still RETAINED (its single reconciliation GET answered 503, or no valid read has happened yet: reconcileLockedOwner schedules nothing further), the wallet's unlock emits accountsChanged([A]) for the very account the click and the owner were bound to. accountChanged(A) sees a!==this.s.account (null), wasFlow=true because retainedOwners.length>0 (:529), and line 533 runs cancelOwners('context-switch'), overwriting the owner's 'lock-reconcile' reason (authLifecycle.abandon rewrites cancellationReason). automaticCleanup('account-switch') with no displayed session plans 'verify-owner' and revokeAbandoned POSTs /api/auth/logout {expectedNonce} with the live cookie the verify installed; the server matches cookie+nonce and revokes. Nothing compares the returning account with owner.account. Real wallets emit exactly this pair (accountsChanged([]) on lock, accountsChanged([A]) on unlock), and unlocking is the natural next user action while the account shows as locked, so the brief's control 'lock-503 then later valid canonical receipt must release lock owner' is defeated whenever the unlock precedes the next read.

      Captured contexts (single tab, single cookie jar): owner flowId 1 account A; lock -> gen+1; unlock -> gen+2; cookie alias = session S1 created by the click's verify (nonce N1). Counts: prompts 1, challenge 1, verify 1 (200, committed, Set-Cookie applied), reconciliation GET 1 (503), cleanup POST 1 (expectedNonce, 204), hints 0, RPC 0. Rows before unlock: sessions created 1 / live 1 / revoked 0, challenge used 1, owner RETAINED reason lock-reconcile, direct GET /api/auth/session signedIn:true. After unlock: live 0 / revoked 1, signedIn:false, owner CONSUMED reason context-switch, client session null. cleanupPlans: [{1,lock,reconcile},{2,verify-settled,reconcile},{3,account-switch,verify-owner}] (P4) or [{1,lock,reconcile},{2,account-switch,verify-owner}] (H2).

      Separation: reproduced = rows/requests above on candidate and parent. Team claim: auth-v11 covers lock->503->restore()->stop and lock->stop plus the lock-idle/lock-active kernels; no public control performs lock -> unlock(same account) while the owner is RETAINED. Unmeasured: real wallet lock/unlock event shapes beyond the injected provider. Fix preserving intended behaviour: in accountChanged, when a retained owner has cancellationReason 'lock-reconcile' and a===owner.account (same provider), keep the reconciliation-only disposition and run reconcileLockedOwner (canonical post-fence read) instead of cancelOwners('context-switch'); only an account different from owner.account is a switch. Optionally retry the reconciliation read on a bounded timer/visibility so the owner does not sit unresolved.

      Case P4 (verify held before the Worker, lock while in flight, reconciliation 503, unlock same account with reads healthy):

      p.switchTo(null);await flush(5);bad=true;release();await flow;await flush(20);await new Promise(r=>setTimeout(r,20));

      console.log('mid',rows(w).counts,q.c.lifecycleSnapshot.cleanup,logouts(q).length); // live 1, RETAINED lock-reconcile, 0 logouts

      bad=false;p.switchTo(A);await flush(20);await new Promise(r=>setTimeout(r,30));await flush(20);

      console.log('after',rows(w).counts,q.c.lifecycleSnapshot.cleanup,logouts(q).map(e=>({nonce:e.nonceAssertion,status:e.status})),await (await b.get('/api/auth/session')).json(),prompts([p]));

      Case H2: intercept returns the verify 200 with body '{' (headers/Set-Cookie applied, body invalid) and sets bad=true so the reconciliation GET answers 503; then p.switchTo(null); then p.switchTo(A).

      Expected (INFO-1 closure: preserve the committed session; a valid post-fence read releases the owner): 0 logout requests after the unlock, sessions live 1, GET /api/auth/session signedIn:true, owner RELEASED after the next valid read.

      Actual at 7215c5d (measured, both cases): after lock: sessions created 1 / live 1 / revoked 0, owner RETAINED cancellationReason 'lock-reconcile', logouts 0; after unlock(A): POST /api/auth/logout {expectedNonce} -> 204, sessions live 0 / revoked 1, GET /api/auth/session {signedIn:false}, owner CONSUMED cancellationReason 'context-switch', client session null, prompts 1 (the signature is wasted). Parent c4f451b (same probe): the lock itself already sent the nonce logout (H2: live 0 after lock; P4: challenge invalidated 1, sessions created 0), so the candidate is better at the lock event and identical in end state.

    • lowLOW-2 side effect (regression vs parent): a sibling-tab channel message while the wallet prompt is open makes the client silently discard the valid signature; the same sign-in needs a second personal_source/src/world/auth.ts:442

      State: open (new in R8 v1.1; parent c4f451b completes the sign-in on the same event order). Blocker: no for authority (fails closed: no session is created, the signed challenge stays pending until its server deadline); listed because one user intent ends up needing two wallet signatures with no notice explaining that the first was dropped, which the brief counts under unintended prompts. Severity Low. From audit_flow 521e4207.

      Mechanism (reproduced): the post-signature gate canSign() (auth.ts:421) requires click.preflight.readSeq===this.sessionReads. The channel listener (auth.ts:257) calls restore() for every message regardless of a busy click (visible() at :181 does check !this.busy). That ordinary read increments sessionReads, so after the prompt returns the sequence no longer matches even though the newer canonical answer is the same ABSENT (lifecycle.know(ABSENT) keeps the receipt, only the sequence comparison fails). The pre-flight stage has a one-shot re-read for exactly this overtaking case (auth.ts:386-389); the post-challenge (:436) and post-signature (:442) gates do not: line 442 ends the click with phase idle and notice null (sessionUnknown() is false because knowledge is ABSENT). Wallet prompts stay open for seconds to minutes, so the window is wide: any BroadcastChannel message from a same-origin tab (a sibling's signed-out after its own logout or switch, or a hint for a session already cleared again) triggers it. If the newer read says PRESENT/UNKNOWN the existing knowledge check already blocks, so accepting a newer valid ABSENT would not weaken the gate.

      Counts (candidate): prompts 1, challenge 1, verify 0, cleanup 0, hints received 1, session GETs 3 (page load, click preflight, hint read); rows: sessions created 0; challenges 1: used 0 / pending 1 / invalidated 0; no cookie; client phase idle, sessionKnown true, session null, notice null. Event order: START -> SIGN_CLICK -> GET session ABSENT (readSeq n) -> POST challenge 200 -> personal_sign opened -> CHANNEL_MESSAGE -> GET session ABSENT (readSeq n+1) -> signature returned -> canSign() false -> click ends. Parent: prompts 1, verify 1 (200), sessions created 1 / live 1, challenge used 1.

      Separation: reproduced = the above on candidate and parent. Team claim: AUTH_STATE_MACHINE.md line 11 ('A newer ordinary read invalidates a receipt by read ordering; a valid superseding read permits at most one new per-click GET') is implemented only before the challenge. Unmeasured: real browser BroadcastChannel timing. Fix direction: mirror the pre-flight rule after the prompt (accept a superseding read whose knowledge is valid ABSENT as the click's receipt, or perform the one per-click re-read before verify), or skip/defer the channel-triggered restore while a click is busy as visible() does; if the click must still end, set a notice (e.g. session-unknown/challenge-lost) so the discarded signature is not silent.

    • lowOwnership request queued behind a failing proof inherits that failure instead of re-evaluating with its own proof (pre-existing, contradicts OWNERSHIP_FRESHNESS.md serialisation rule)source/server/ownership.ts:228

      State: open, not a regression (identical on public parent c4f451b). Blocker: no. It is fail-closed (503 OWNERSHIP_UNAVAILABLE, never an empty complete home), grants no authority and expands no method or header, so it is an availability defect, not an Auth/ownership invariant failure. From audit_economics 57507b65.

      Mechanism (reproduced): proof() serialises per-address updates by chaining a waiting caller on the in-flight update with pending.then(onFulfilled) only. When the in-flight update rejects (a first or expired-epoch proof whose Multicall3 ownerOf eth_call failed, or a proof completing at/after its 30 s deadline, :292), the rejection propagates through .then() to every caller queued behind it. The queued caller never runs its own update(): no ownerOf RPC is attempted for it even if the node has recovered, and its own captured roster and fresh intent are not re-evaluated. This contradicts OWNERSHIP_FRESHNESS.md line 20 ('A caller waiting behind another request re-evaluates its own captured roster and fresh intent') and the stated availability design ('First/expired proof failures ... their retries remain unavailable and are bounded by existing request limiters'): the waiter is refused without any retry. The existing ownership-v11 controls queue callers only behind successful updates.

      Counts (reproduced): index reads 1, ownerOf RPC 1 (the failed one), lane calls 0; first request rejects OWNERSHIP_UNAVAILABLE (correct), second (queued, node healthy) also rejects OWNERSHIP_UNAVAILABLE with no RPC of its own; a third request afterwards succeeds (eligible 1, RPC 2). Parent c4f451b: identical.

      Separation: reproduced = the above. Team claim: the serialisation rule in OWNERSHIP_FRESHNESS.md is only partially implemented. Minimal fix preserving the serialisation design: chain on settlement rather than fulfilment, e.g. return pending.then(()=>this.proof(...),()=>this.proof(...)) (or pending.catch(()=>{}).then(()=>this.proof(...))), so the waiter performs its own epoch evaluation and proof after the predecessor settles; a re-run still passes the same budget/lane/limiter gates, so the bounded-RPC argument is unchanged.

      Offline, synthetic fixtures only. From source/ with npm ci --ignore-scripts, tmp/oq.test.mjs, node --test tmp/oq.test.mjs (same gateway/fetcher scaffold as the overlap probe, plus a hold gate and a fail flag on the eth_call):

      const deferred=()=>{let resolve;return {promise:new Promise(r=>resolve=r),resolve};};const st={live:START,rpc:0,failRpc:false,holdRpc:null};

      // in the eth_call branch of the fetcher: st.rpc++; const willFail=st.failRpc; if(st.holdRpc){const g=st.holdRpc;st.holdRpc=null;g.started.resolve();await g.release.promise;} if(willFail)return new Response('{}',{status:502}); ...normal aggregate3 answer...

      const gate={started:deferred(),release:deferred()};st.holdRpc=gate;st.failRpc=true;

      const first=o.home(A,req(START),false);await gate.started.promise; // first proof's RPC is held

      const second=o.home(A,req(st.live),false); // queued behind the held first proof

      st.failRpc=false; // node healthy again before the first failure is observed

      gate.release.resolve();

      await first.catch(e=>console.log('first',e.message)); await second.then(v=>console.log('second ok',v.eligible),e=>console.log('second',e.message,'rpc',st.rpc));

      console.log('third',(await o.home(A,req(st.live),false)).eligible,'rpc',st.rpc);

      Expected (OWNERSHIP_FRESHNESS.md): the queued second request performs its own proof after the first settles: RPC count 2, second request resolves with eligible 1.

      Actual at 7215c5d (measured): first OWNERSHIP_UNAVAILABLE; second OWNERSHIP_UNAVAILABLE with rpc still 1 (no RPC of its own); third succeeds (eligible 1, rpc 2). Parent c4f451b: identical output.

    • lowLOW-6 side effect (regression vs parent): a good world snapshot whose Worker fetchedAt is ahead of the browser clock is classified as a failed read (retry ladder, permanently 120 s for a lagging clocksource/src/world/cadence.ts:62

      State: policy decision with an unmeasured load/UX side effect; open. Blocker: no (not an authority issue; load and display only). Merged from audit_math c5dd4210 and audit_permissions b7888aae.

      Mechanism (reproduced): worldReadResult() compares the Worker's epoch fetchedAt (server/gateway.ts:212, fetchedAt=this.now()-ageMs, Cloudflare's clock) with the browser's Date.now() through isFreshAge, which returns false for any negative age (src/shared/freshness.ts:6). A client whose wall clock is behind the stamp by more than the response latency sees a state:'fresh' sample as 'future' and worldReadResult returns false, the same value as a transport failure. startPoll() (cadence.ts:98-103) then increments failures and schedules nextDelay(false,...): 5 s, 15 s, 30 s, 60 s, then 120 s for ever, instead of REFRESH_MS=900 s after a good read, while the valid data it just received is displayed. The effect is transient when the lag is smaller than the sample's age at the next retry (one or a few extra reads) and persistent for a device whose clock lags by more than the gateway sample age (up to UPSTREAM_TTL_MS, 5 min): that client polls /api/world/snapshot every 120 s (7.5x the designed rate) for the whole session. The same comparison in marketView (market.ts:112) and floorView (market.ts:93) labels a Worker-fallback quote 'stale' (weather 'unknown', floor null) for the same skewed client. Before R8 (c4f451b cadence.ts:59) a future stamp counted as a good read ('behind'/true). FRESHNESS_BOUNDARIES.md records the intent ('invalid/future source fetchedAt cannot count as a good read') and tests/freshness-v11.test.mjs pins fetchedAt 1001 vs now 1000 => false, but neither considers that 'not good' is mapped onto the failure retry ladder rather than onto 'behind' (one bounded follow-up) or a success-for-scheduling. Clock skew of seconds on consumer devices is routine (siwe.ts allows 10 minutes of skew for the sign-in message for that reason).

      Separation: reproduced = the probe below on candidate and parent. Team claim: FRESHNESS_BOUNDARIES.md policy as stated is implemented. Inference/unmeasured: the share of real visitors with negative skew; WorldApp.tsx (withheld) is assumed to feed worldReadResult into startWorldPoll as the public fixture comments describe. Fix that keeps future stamps untrusted: keep refusing to label a future-dated sample fresh, but return 'behind' (or true) for the scheduler when the samples are fresh and the only defect is a bounded negative age (e.g. up to FOLLOW_UP_MS or the SIWE skew allowance), and allow the same bounded skew for remote stamps in marketView/floorView, never rewriting the stamp.

      Actual at 7215c5d (measured): false,true (a 1 ms-ahead stamp is classified like a transport failure); delays [5000,15000,30000,60000,120000,120000,120000,120000], failures 8; market 'stale' 'unknown' floor null.

    • infoGateway shared-copy warm accepts a record dated up to 60 s in the future and rewrites its fetchedAt to now, contrary to the frozen freshness policy ('never synthesize a future stamp', 'reject remote fsource/server/gateway.ts:256

      State: accepted limit / unchanged since the public parent (gateway.ts is not in the R8 change set); reported because the task's freshness controls require rejecting remote future timestamps without rewriting them as now and FRESHNESS_BOUNDARIES.md states 'never synthesize a future stamp'. Blocker: no. From audit_math d6cd077d.

      Mechanism (reproduced): ReadGateway.warm() (gateway.ts:253-259) seeds a cold isolate from the per-colo Cache API copy written by another isolate. Line 254 tolerates age>=-60_000 (a record dated up to one minute ahead of this isolate's clock) and line 256 stores fetchedAt=Math.min(record.fetchedAt,at), re-dating a future record as read 'now', then validUntil=max(entry.validUntil,fetchedAt+ttl) gives it a full UPSTREAM_TTL_MS from this clock and labels it 'fresh' to clients and to the ownership roster read (Ownership.world() uses gateway.source('swarm')). Impact is bounded: the writer is another isolate of the same Worker in the same Cloudflare location, so the skew is Cloudflare's own inter-isolate clock skew, and the roster only names candidates (ownerOf still proves them). It is a documented-policy inconsistency rather than an authority defect, and the exact boundary (age===-60_000 accepted) is untested.

      Separation: reproduced = probe below (candidate and parent identical). Unmeasured: real inter-isolate skew. Fix if the policy is to be uniform: reject age<0 as isFreshAge does elsewhere, or keep the record's own fetchedAt unmodified and let label()/servable() judge it.

      From source/ (offline, injected fetch and clock): node --test tmp/gw.test.mjs with

      const {ReadGateway,SHARED_SHAPE}=await import('../server/gateway.ts');let t=1_000_000;const urls=[];

      const g=new ReadGateway(async u=>{urls.push(String(u));return new Response(JSON.stringify({seats:{},owners:[],count:0,workers:[]}),{status:200});},()=>t,{sharedWaitMs:50});

      const shared={async get(k){return k==='swarm'?{v:1,shape:SHARED_SHAPE,key:k,data:{seats:{},owners:[],at:1},fetchedAt:t+59_000}:undefined;},async put(){}};

      const s1=await g.source('swarm',undefined,shared);console.log(s1.state,s1.fetchedAt,t);t+=4*60_000;const s2=await g.source('swarm',undefined,shared);console.log(s2.state,s2.fetchedAt,t,urls.filter(u=>u.includes('/swarm')).length);

      Expected under the stated policy: a shared record dated 59 s in the future is not usable as current data (ignored, or kept with its own future fetchedAt so downstream freshness gates reject it).

      Actual at 7215c5d (measured): prints fresh 1000000 1000000 (accepted and re-dated to this isolate's now) and at +4 min still fresh with fetchedAt 1000000; parent c4f451b identical.

    • infoPublic scheduler test writes evidence artifacts outside source/ into the review repository root, embedding an absolute local path and a non-reproducible run idsource/tests/auth-reference-scheduler.test.mjs:9

      State: open (hygiene). Blocker: no. From audit_economics 553671b9.

      The recorded public filtered-subset command (Submission7_R8Closure/TEST_RESULTS.json) includes tests/auth-reference-scheduler.test.mjs, whose save() helper (line 18) writes into resolve(import.meta.dirname,'../../evidence/reference-scheduler'), i.e. /evidence/reference-scheduler, one level above the published source/ tree. A reviewer who runs the exact recorded command from source/ ends up with untracked JSON files in the review repository root (fixed--.json, focused-.json, gate---RESULT.json, LATEST.json). Each fixed/focused file embeds provenance().sourceRoot, an absolute local path, and the gate file name contains a wall-clock timestamp and random UUID, so the artifacts are not byte-reproducible and are easy to commit by accident into a package whose manifests (submission7-r8closure-published-source.json, SHA256SUMS, BOUNDARY_CHECK.json) do not cover them; TEST_RESULTS.json's sourceUnchangedDuringRun receipt only speaks for source/.

      Reproduced fact: after the recorded command in a scratch copy of source/, the sibling directory evidence/reference-scheduler held 18 JSON files (13 fixed-, 3 focused-, 1 gate-*-RESULT.json, LATEST.json) and fixed-0-lost-hint.json contains "sourceRoot": "". Minimal fix: write artifacts under a path inside source/ that .gitignore already excludes (source/.gitignore ignores tmp/), or honour an explicit output environment variable and skip persistence when it is unset; record the artifact location in TEST_RESULTS.json if artifacts are meant to be part of the receipt.

      From a clean checkout of commit 7215c5d: cd source && npm ci --ignore-scripts && node --test --test-reporter=tap --test-concurrency=3 tests/auth-reference-scheduler.test.mjs then cd .. && git status --short && ls evidence/reference-scheduler | wc -l && grep -o '"sourceRoot": "[^"]*"' evidence/reference-scheduler/fixed-0-lost-hint.json.

      Expected: no files created outside source/ (or only under an ignored path).

      Actual (measured on a scratch copy): the directory evidence/reference-scheduler is created beside source/ with 18 JSON files, the fixed/focused files carry the absolute sourceRoot of the running machine, and the gate RESULT file name carries a timestamp and UUID; in the repository this appears as ?? evidence/ in git status.
