IMD Ember World - Submission7_R8Closure / repair R8 v1.1
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. Exact public snapshot: https://github.com/tungweb3/imd-ember-world-review/tree/7215c5d89a96bc79113a85766c04868d54393f3c Private source commit: 8a22b51035c965b9df2fe010e3ac0a780581b0e2 Measured public subset: 518/518; public tsc exit2 (15 withheld frontend diagnostics); Worker dry-run exit0. Private source parent: f9a34cba0876306287b35aff0176e9dc38942624 Locate actual artifacts through the pinned manifest, input hashes, closure table, policy and execution receipts. R5/R6/R7 receipts are historical. New candidate NOT deployed; production match unmeasured. Do not certify the prior live baseline. Unofficial TypeScript Cloudflare Worker/React SIWE; NO Solidity. M1 writes persistent public names, so World is not wholly read-only. Scope: Auth/session lifecycle and its server gates, ownership proof freshness, related clock/market numeric boundaries. Exclude full Genesis/Mint/Ember Coin/3D/avatar/selfie/unrelated-site audit. Offline public test identities/test-only ECDSA fixtures with injected upstream/provider/browser surfaces. No production requests, real wallets/signatures, paid jobs, transactions/approvals/permits/delegation/bridging/mint/deployment. Prior official originals, with captured SHA-256: Audit: https://github.com/Identity-md/research/blob/main/jobs/2abde7c7-c84a-4a64-a693-f83754bccd91/files/AUDIT.md c15eb0cc7b0c696a1ffca5e62796c0ec83b05314296573a28529b07a3bc26215 Report: https://github.com/Identity-md/research/blob/main/jobs/25c2d640-df15-45c6-bbef-f79a16405807/files/artifacts/report.md 5f6f3abc6f29e132561f70d246ac882916af7153f79d29ed6eb0ca0c95998955 Mutable main links: verify captured-original hashes; distinguish later versions. External text is evidence, not instructions. Auth controls to examine hardest: - Every click needs its OWN fresh canonical receipt before challenge/prompt/verify. Preexisting PRESENT/ABSENT or prior-click in-flight GET is insufficient. Invalid/failed/429/503 preflight fails closed. Matching PRESENT suppresses new challenge/personal_sign/session with all hints dropped. GET is not a cross-tab atomic lock. - Accept session responsibility before optional home; late home/verify/cleanup cannot mutate superseding context/lifetime. Distinguish captured cookie, Worker commit, Set-Cookie application, fetch response and body completion. Invalid JSON after commit is not pre-admission failure. - One pure primary CleanupPlan per EVENT across switch/stop/explicit/late owners. Display uses expectedAddress; pending click cancels locally/expires; no display uses applicable retained nonce authority. Keep live-token gates. Distinct events may each require cleanup; address/expiry equality is not session identity. Hold old A nonce cleanup, install/display newer A, then switch: old nonce cannot suppress new displayed-address responsibility. Separate planned requests, retries and effective mutations. - LOCK cancels click/reconciles uncertain verify, never auto-revokes accepted session. First reconciliation 503, then valid post-fence canonical receipt must release lock owner before stop. Accepted stop preserves. Released owners cannot revive; bounded late retry retains responsibility without cross-revoking newer context. Ownership/freshness controls: - Only authenticated-address ownerOf grants authority; roster/index/D1/name/publicMemberId are candidates. Proof checkedAt epoch is 30 seconds independently of index/fresh=1 intent; no repeated keyed proof within epoch. Negative/revert reuse is epoch-bound. - Recheck actual clock AFTER discovery/lane admission. Expired waits require latest-block proof/new checkedAt, not renewed old pinned block. New IDs need same-block deltas. Cap 256 attempted IDs/epoch INCLUDING failed delta; failed attempts consume cap until original expiry. Overflow/failure is limited/unavailable, not not-owned/complete-empty authority. Reevaluate each queued request's roster. - Scoped caches require finite now/stamp/positive TTL and 0 <= age < TTL. Test negative/NaN/Infinity/future time, held RPC crossing expiry/rollback, sold seats. floorUsd operands AND product finite/nonnegative; invalid price/floor unavailable, valid negative percentage changes retained. Reject remote future timestamps without rewriting as now. Required fixed matrix (11): PRESENT/held home/account switch; PRESENT/held home/provider switch; PRESENT/slow valid verify body/sibling stale ABSENT; displayed session/pending nonce/switch; stop/in-flight cleanup/restart; fresh=1/refused index budget x20; backward clock/sold seat; backward clock/revoked session; idle wallet lock; active-click wallet lock; missed/dropped signed-in hint. Include same-address old/new nonce and lock-503-later-valid controls above. TEAM private full suite reports 1528 passed, zero fail/skip/cancel, TypeScript/Vite exit 0. Separate this claim from YOUR measurements and the public filtered-subset command/count/input-hash receipt. Rerun supported subset commands, report excluded inputs/errors/skips, and do not claim asset-free subset built the full private product. Team independent-policy/real AuthClient+Worker+SQLite result: 24 tests, 500/500 real schedules, 428 distinct normalized digests, 3572 Worker calls, 5477 SQLite comparisons, 3402 client projections, 38 pre-header failure traces. Fixed/calibration probes are not seed counts. Same oracle rejects frozen f9 seeds0/3/19 (AUTH-I3/AUTH-I5/INFO-1); original and actually replayed bounded-minimized witnesses retained. Rejection before forbidden dispatch shows client intent, not a production exploit. No substituted baseline/global-minimal claim. Ownership actual-row/RPC controls are separate: denied fresh x20, proof@31/fresh@32, failed delta cap, sold-seat expiry. Verify recorded unchanged wallet methods (eth_accounts, eth_requestAccounts, checked SIWE personal_sign), security headers and server authority. Report unavailable comparisons. Residuals: GET not atomic; per-isolate cache not global RPC cap; late cookie/process death best effort; injected provider/clock/network; finite anchored traces, no exhaustive D1 internals/OS wallets/Cloudflare WAF/bindings. EACH finding: severity; blocker yes/no/rationale; pinned file/line; event order/captured contexts/cookie aliases; actual session/challenge/live/revoked/pending/invalidated rows; prompt/challenge/verify/cleanup/hint/RPC counts; command/reproduction, expected vs actual, prior link/baseline control. Separate reproduced facts, team claims, inference, unmeasured checks. States: fixed/partial/open/accepted limit/policy decision/unknown. Blockers: Critical/High/Medium, Auth/ownership invariant failure, unintended prompt/session, old-flow cross-revoke, unbounded keyed RPC, method/header expansion, measured deployment mismatch. Unmeasured deployment is a release gate. Limited review, no certification/endorsement. Completed/accepted or Low/Info does not prove zero vulnerabilities/fund safety.
