IMD Ember World: post-remediation review of sixth results (package R7).
IMD Ember World: post-remediation review of sixth results (package R7). Deliver Traditional Chinese report.md with English identifiers/paths and evidence index. Review security/correctness/availability of TypeScript Cloudflare Worker/React World/Auth/Member M1, not finance/Solidity. Earlier sixth jobs completed. PIN: https://github.com/tungweb3/imd-ember-world-review/tree/c4f451b015abdaced6c35a717b29f5bb1cb351c0 ; public parent445747d6a4d4fb6fa4eaa9c67b74e3e2bd9c1703. Auth ff6bed8; deployed e48a94f (full hashes in R7 docs). Supplied 111-file scope identical at both before redactions. Private history, full frontend/WorldApp/scene/geometry, models/textures/media and unrelated features/tests withheld. Do not request/reconstruct/add them. READ README and its R7 links: AUTH_REMEDIATION, PRIOR_REVIEWS, TEST_RESULTS, BUILD_EVIDENCE, PRODUCTION_DEPLOYMENT, PUBLIC_SOURCE_VALIDATION, PUBLIC_CONTENT; manifests/r7-published-source.json; source/docs/security/AUTH_STATE_MACHINE.md and prior R5/AUD4 security docs. R5/R6/TESTS are historical. ORIGINALS: verify fingerprints in R7/PRIOR_REVIEWS.md. Audit: https://github.com/Identity-md/research/blob/main/jobs/09062f1d-1a0b-49cb-af81-e55978798576/files/AUDIT.md . Report: https://github.com/Identity-md/research/blob/main/jobs/816968c0-8ff9-40a9-8e08-0e0bc4f2aef1/files/artifacts/report.md . Retest four Low findings + cache Info#5. ReportR6-I1 duplicates Audit#2; Info#6 is a verdict matrix, not a bug. Retain fifth Low verdicts/R5-01..09. Completed/accepted is delivery, not certification. METHOD: offline pinned source/local synthetic tests; real Worker/routes/SQL+node:sqlite with in-memory EOA/cookie/provider/upstream/clock/channel/body fixtures allowed. Same evaluator before/after plus controls; never weaken expectations for parent pass. Missing baseline/dependencies => precise UNKNOWN, not guessed result/private geometry stubs. Optional live: TWO anonymous GETs maximum, >=5s apart, only https://imdember.com/ and https://imdember.com/api/auth/session ; no cookies/credentials. Record UTC/status/hash/headers; stop on denial, no bypass. No asset discovery/download, live wallet/auth/signing, authenticated requests, POST/PUT, scan/fuzz/flood, D1 mutation/deploy/messages. Synthetic local POST/PUT allowed. EVIDENCE:111 source =95 exact+16 redacted/57 mask lines; original masked fingerprints withheld. Independently run supported public population recorded386/386 across11 files, no skips/scene stubs. Private Auth1357/1357 and deployed full1392/1392 are team evidence, different populations, not public execution. Public tsc exit2/16 diagnostics (15 withheld imports, one derived implicit-any), full frontend unbuilt. Worker sandbox first failed; compiler retry raw314508B/SHA256 afd82f506aceb57ca85ce44ff6c7e65146546d383ae2e2b2b7feca72bd23e92a matches record. Same-depth dependency-junction limit; empty ASSETS fixture not website, no normalization. Keep failures/commands/counts/fixtures/skips. Before/after counts in R7/AUTH_REMEDIATION.md are team claims, not public runs. MANDATORY BEFORE/AFTER + CONTROLS: Audit#1 (46-68): uncertain verify accepts PRESENT, holds home; terminal RELEASED before home await. Stop/late home cannot revive old released verify-owner cleanup. Distinguish legitimate expectedAddress context-consistency cleanup on account/provider change. Test direct success, PRESENT/ABSENT, stale callbacks, newer B/A2; terminal owner has zero authority. Audit#2 (70-93), ReportR6-I1 (113-121): dead token+exact nonce must not authorize cleanup/cookie changes. Require token+nonce+revoked_at IS NULL+expires_at>now. Missing/empty/forged/expired/revoked/mismatched, original challenge present/pruned, newer B/A2/pending controls must preserve unauthorized rows/challenges/cookies. Any token forbids pending-only fallback; NO token permits only original flow cookie+exact pending/unexpired nonce. Test live controls, address fallback live matching cookie/original flow, both assertions400, explicit user /logout {} semantics, R4-01 logout-all guard. Audit#3 (95-117): pre-commit channel GET ABSENT starts before verify commit but arrives after headers with stalled body; cannot release unresolved owner and prevent stop cleanup. Fence = latest read sequence at headers/transport observation; newer than VERIFY_START alone insufficient. Test pre/post-fence ABSENT/PRESENT, stale reads, invalid responses, early refusal dispatched before headers/later drain, repeated cancel/late body. One owner/one in-flight cleanup; RELEASED/CONSUMED cannot revive or mutate newer life UI/timer/hint/channel. Audit#4 (119-139): A clicks during held initial session read, accountsChanged B; B must not inherit A's challenge/verify/personal_sign. Bind click provider/account/generation/lifetime. Test provider/account/lock/stop/restart, queued old callbacks, same-address/silent substitution, unbound initial connection/event agreement. UNKNOWN cannot prompt; fresh click can recover after trusted read. Info#5 (141-155): negative wall-clock age must expire public-name cache in BOTH publicName/lookupName. Repeated jumps, TTL/fresh hit, pending/debounce/failed refresh/stopped callback. Separate name cache from preserved monotonic rename cooldown. REGRESSION MATRICES: R5-01..09 are controls, not nine new bugs: account switch; provider/newer context; teardown; malformed UNKNOWN; invalid positive schema; GET before signing; no duplicate session/prompt; backward clock; timer/server reconcile. Strict schema: signedIn===false+optional boolean expired, or true+valid address+positive safe-integer expiry. Invalid JSON/type/address/expiry,429/503/transport =>UNKNOWN; next click reads first. Rename cooldown =serverTime+monotonic time, deadline GET decides unlock; invalid/failed refresh stays cooling with positive retry, stale account/life cannot unlock new UI. Simulated timers do not prove OS suspension. Retest R4-01 displayA/cookieB logout-all409 before writes, missing/dead authority/no false all-device-success; stored SIWE; R3/AUD3/N/ADV/Enter/Home where supplied; M1 version race, atomic five-attempt budget, no-op/idempotency, request/probe bounded retention/cleanup, uncertain-save expiry. House authority=session address+Ethereum mainnet ownerOf/eligibility, never names/roster/memberID. Methods only eth_accounts/eth_requestAccounts/exact SIWE personal_sign. No Mint/Solidity/Coin E1/0007/rewards/transactions/approvals/Permit/typed-data/batch/delegation. RETAIN: R4-03 smart-wallet write policy partly; R4-09 availability partly; AUD3-05 partly; AUD3-09 review-limit. Lost A token cannot authorize A revoke after B replaces it; address-only cannot distinguish same-wallet renewal. Live-authorized old Set-Cookie clear may remove newer browser cookie while row survives. Cleanup best effort while JS runs, not offline/termination guarantee. No new auth-fetch bounded deadline. Real provider/browser/OS, production D1 races/cron/WAF/limiter/upstream and withheld content remain unknown. DEPLOYMENT partial/team, see R7/PRODUCTION_DEPLOYMENT.json: 100%; five anonymous GETs/four static hashes/24 headers/signedIn:false/no-store/no Set-Cookie; three anonymous functional viewports. No migration/config/header change. Byte/GET match is not Auth/wallet/concurrency or omitted-feature proof. No private asset fetch. DELIVER four-Low+cache and R5 matrices: fixed locally/partly/open/unknown, blocking/nonblocking. Cite immutable file:line, preconditions/impact, event ordering, repro/argument, prompts/cookie presence, created/live/revoked rows, pending/used/invalidated challenges, knowledge/state/cleanup/UI/timers/profile version (N/A explained). Separate measurements/team claims/inference/unknown. Seek all-severity regressions. Tests/Low labels/delivery do not certify closure/approval/fund safety.
