Dungeon Crawler Pepe (DCP)

the task produced no changes; the agent's last message was: Blocked by the execution environment. All three tool attempts failed with:

failed to spawn code-mode host
/home/ubuntu/.local/bin/codex-code-mode-host:
No such file or directory (os error 2)

I could not read the pinned inputs, create files, run tests, or publish source. No repository changes or external actions were made.

The environment needs its code-mode host restored before I can complete the build and review. The requested deliverable remains unimplemented and unverified.

Delivered the local game, static export, hardened contracts/backend, recovery tooling, and source bundle.

Verified: 41 Solidity tests, 30 Node tests, forge build, forge fmt --check, 120-player simulation, and backup/restore.

Run with Node 24+: node scripts/demo.mjs, then open http://127.0.0.1:8787.

Not launch-ready: GitHub publication, independent review, funding, and production integrations remain unresolved in launch readiness. No contracts were deployed or paid services initiated.

Implemented the responsive game interface, static browser practice, accessibility fixes, source lockfile and documentation.

Passed: production build, typecheck, 32 Node tests, 41 Solidity tests, mobile/desktop browser checks and two durable content cycles.

Run locally with Node 24+: node scripts/demo.mjs.

Not launched. Public GitHub publication, independent sign-off, funding and production integrations remain outstanding, documented in docs/launch-readiness.md. Complete source handoff: artifacts/dcp-source.tar.gz.

the task produced no changes; the agent's last message was: I couldn’t inspect or modify the repository: both command attempts failed because the execution host is missing:

/home/ubuntu/.local/bin/codex-code-mode-host

No files were changed, no tests ran, and nothing was published or deployed. I can’t assess the existing implementation or claim completion without repository access.

Restore the execution host and rerun this task so I can read the accepted work, implement scoped fixes, and check the deliverable.

I fixed one problem the earlier review had already documented: three server database tables were never cleaned up and would grow forever. The full suite passes: 33 Node tests, including a new one. The previous attempt was rejected because its tool host was missing and it changed nothing. This time the environment worked.

Starting state. Before changing anything I ran the existing checks. All 32 Node tests and 41 Solidity tests passed, formatting was clean, and rebuilding the browser export changed no files. There was no failing finding to repair, so I took an open item from docs/review.md that falls inside the paths I'm allowed to edit.

The problem. The scheduled housekeeping job cleared the old action log but not three related tables:

• action_requests: a fingerprint kept for each player action so a retry can be recognised.
• expired sessions: login tokens past their expiry.
• stale nonces: one-time codes used for wallet sign-in.

The fix (34 lines added, 3 removed, across 5 files):

• server/src/auth.js: a new pruneAuth deletes only sessions and nonces that sign-in already rejects, using the same clock and time limits. Deleting them can't change any sign-in result.
• server/src/game/service.js: pruneActionLog also deletes fingerprints whose log entry is gone. A fingerprint and its log entry are always saved together, so the only way to lose the log entry is this cleanup. If an old action is retried after cleanup, it is still refused as out of date, never applied twice.
• server/src/ops/keeper.js: the scheduled housekeeping step now also calls pruneAuth.
• test/runtime.test.mjs: a new test runs housekeeping eight days ahead. It checks that old rows are removed, that a live session and a fresh nonce survive, and that retrying the old action is refused. It fails on the old code and passes with the fix.
• docs/review.md: the open-issue entry now records the fix and the test.

Left unchanged: contracts, scripts, dist/ and the configuration files. The browser export doesn't include any of the files I edited, and rebuilding it produced no changes. I didn't commit anything.

Noticed but not fixed (outside my allowed paths or scope):

• README.md and REVIEW.md link to files under artifacts/ (browser-check results, test logs, the source archive) that don't exist in this checkout. Those two files sit at the repository root, so I couldn't edit them.
• The serious launch blockers in docs/launch-readiness.md are still open. They include factory and fee-routing proof against the real deployed contracts, a production swap and price source, the x402 payment flow, connecting the prize-randomness contract to the backend, safe transaction sending, funded hosting, independent review and public GitHub publication. The launch decision remains NO-GO, and nothing was deployed, published or paid for.
