Created both requested atlases:

• artifacts/art/characters.png
• artifacts/art/world.png

Both are 1254×1254 transparent RGBA PNGs. Integrity and transparency checks passed.

Delivery notes record layouts, provenance and limitations: uneven padding, fringe pixels and unverified animation loops still require cleanup before production integration.

Implemented the illustrated frontend and rebuilt dist/ with 134 sprites. Build, typecheck, 24 tests, browser checks, and 16/16 design checks pass.

Source patch · Validation and evidence

IMD refused manual publication: its plane hosts job previews after submission. The preview clearly labels recorded mode because live CORS is blocked. The VPS and simulation remain unchanged.

The review found nothing in the build that should stop it being hosted. I recorded one medium attribution finding in .imd-findings.json and changed no other files.

What I read in dist/: index.html, both config JSON files, the art manifest, all seven scripts in dist/assets/, the license files, the art atlases and the share image. I searched the scripts for URLs, eval/new Function, iframes, redirects, importScripts, wallet and signing calls, seed-phrase or private-key prompts, and giveaway or token wording. I then read the code around each match.

No critical or high findings:

• Wallet code: it is only in the old settlement client (Legacy-DjIznllY.js). That client loads only if expanse-config.json reports legacyAvailable === true, and the hosted config sets it to false. Even when it does load, it asks for one plain sign-in message and says "No transaction, fee, or private key." There are no approvals, permits or transfers.
• Wallet logos: the MetaMask, Coinbase, Phantom and Rabby SVGs label "Open in …" links. That points to the real wallets; it doesn't pose as any of them.
• Remote code: none is downloaded and run. The only external host the main script contacts is the owner's own server (stratoks.2-29-11-211.sslip.io) for read-only GET requests that send no credentials. The demo and learning workers make no network calls.
• Content: there are no hidden iframes, redirects, obfuscated scripts or financial claims. The atlases and share image show an original golden-rabbit world with nothing objectionable.
• Hosted copies: the art, manifest, license and config files in dist/ are byte-identical to those in web/public/. The atlas checksums match the manifest.

The finding (medium, advisory): the repository gives two conflicting accounts of where the art came from.

• docs/ASSETS.md:3 still says the art is drawn in code and that "No … AI-generated image … is used."
• The hosted dist/art/manifest.json:5 and docs/art/DIRECTION.md credit the atlases the renderer now uses to OpenAI image generation.
• The hosted dist/licenses/client-and-art.txt doesn't mention the generated atlases either.

The fix is to correct docs/ASSETS.md and the license note.

Review complete. The findings file holds three substantiated defects, none blocking. The working tree is otherwise unchanged except for .imd-findings.json.

What I verified as correct

• No server, shared, test, deploy or build-config files changed from the pinned commit. The live world ID, simulation and data are untouched.
• Rebuilding web/ produced a byte-identical dist/. Typecheck passed. Client tests pass (17) and the expanse tests pass (7).
• All 134 sprite keys the renderer requests exist in the atlas, and the shipped PNGs in web/public/art and dist/art are identical.
• Projection round-trips, viewport query coverage and pointer-stable zoom hold across 390, 851 and 1440 at all tested spans and chunk edges. The server caps views at 96 tiles, which the client respects.
• Shelter artwork is state-truthful: the engine only exposes completed shelters. Fires come only from the engine's fire list. Carry pose requires confirmed inventory. Unsupported actions such as drink and shelter fall back to idle.
• The live API really omits the CORS allow header for foreign origins, so the recorded default start mode is an honest external limitation, not a fake.
• Mobile at 390 px: the inspector sheet opens below a shrunken canvas and does not cover the selected creature. No horizontal overflow, no JavaScript errors.

Findings, ranked

1. Medium, terrain cache invalidated by every camera move (web/src/expanse/worldRenderer.ts:140). The ground cache key includes camera x, y and span. Measured on the shipped build: idle frames draw in about 1 ms, but each drag or wheel-zoom frame rebuilds the whole ground canvas at 34 to 38 ms, over the renderer's own 32 ms budget. Follow mode triggers the rebuild on every received frame. The author's performance table only measures a static camera.
2. Medium, contradictory art provenance (docs/ASSETS.md:3). The asset document says no AI-generated image is used, while the shipped manifest and art direction credit OpenAI image generation for the atlases the renderer actually draws. The licence file also omits the generated atlases. This confirms the earlier specialist's finding.
3. Low, npm test skips the expanse tests (web/package.json:10). The documented test command only globs the top-level tests, so the projection, appearance and transport gates are not run by the reproducible build instructions.

Missing deliverables noted, not defects

• No pan, zoom or follow performance measurement was recorded, only static-camera synthetic fixtures.
• The review preview defaults to a frozen recording. Live mode needs the owner to allow the hosting origin in the server's CORS allowlist, which is outside the contributor's control.

Saved 5 verified findings: 1 high, 4 medium in .imd-findings.json. Application files remain unchanged.

• High · bug: Short phone layouts cover the main actions and clip navigation controls. At 667×390, the tool rail extends 111px below the world. Source
• Medium · accessibility: Enter on the minimap moves to an unchosen position, with different destinations in Chromium and WebKit. Source
• Medium · bug: At 320px, following a resident covers Connect live with the follow banner. Source
• Medium · fidelity: Residents travelling toward work display gathering or idle poses instead of walking. Confirmed live frames reproduce this. Source
• Medium · fidelity: The requested readable settlement paths are absent; shelters sit in uninterrupted grass. Source

Typecheck, 24 tests, build, 134-sprite validation, and 12 rendered picking cases passed. A clean rebuild matched all 29 shipped static files byte for byte. Chromium and WebKit interactions passed at the requested widths, subject to the findings above. Real polling and reconnect worked through a read-only validation proxy; direct preview access lacks the required CORS permission.

STRATOKS presents a persistent simulation as a sunny, painted miniature world framed by a dark moss observer HUD.

Fixed all eight findings and rebuilt dist/.

Passed: 27 tests, typecheck, build, Chromium/WebKit interactions and 16 design checks. The patch rebuilds byte-identical output. Submission is under 8 MiB.

Responses · Validation · Patch

CORS restrictions and measured zoom spikes are documented. VPS untouched; export ready for IMD’s automatic preview publication.

The previous attribution finding is fixed: documentation, manifest, and hosted license consistently credit the generated artwork.

Verified local rendering at 390, 851, and 1440 pixels without JavaScript errors. No remaining findings.

Wrote {"findings":[]} to .imd-findings.json. Project files remain unchanged.

.imd-findings.json contains {"findings":[]}. Tracked repository files are unchanged.

All five previous findings are settled:

Independent checks passed: 27/27 tests, typecheck, build, 134 sprite validations, eight viewport sizes in Chromium and WebKit, and 12 picking cases across zoom levels and positive/negative chunk boundaries. All 29 rebuilt static files match shipped dist/ byte for byte.

Fresh read-only live testing observed world-20260101-0, ticks 182792–182803, with 171 residents changing position. Selection, follow, pan, zoom, minimap, interruption and reconnect passed without unexpected JavaScript or local-resource errors.

The requirement checklist below carries forward accepted work and records the targeted rechecks. Source filenames without a prefix are under web/src/expanse/.

All three prior findings are fixed. I reproduced each author claim against the current tree and found no new defect, so the findings file holds an empty list.

Terrain cache (medium) is fixed. The ground cache in web/src/expanse/ground.ts now rasterizes fixed 8x8 world-coordinate chunks keyed by tile signature, and pan or zoom only rescales existing paint. I re-ran my original reproduction on the shipped dist in headless Chromium, reading the canvas draw-time samples:

Previously every drag frame took 34 to 38 ms. The remaining zoom spikes come from newly exposed chunks being rasterized, which the author documents honestly in the revision report without claiming a frame rate. No page or console errors occurred. The unit test in terrain.test.ts checks that camera changes do not increase the build count and that terrain or world changes do.

Provenance contradiction (medium) is fixed. The asset document now credits the active atlases as original contributor artwork generated with OpenAI image generation in 2026, labels the old code-native renderer as archived, and the same statement appears in the manifest and in both the public and dist licence files.

Test discovery (low) is fixed. The unchanged npm test script now runs 27 tests and passes, because a top-level aggregator imports the projection, appearance, transport and terrain suites.

Preservation checks. Server, shared simulation, deploy, tests, package manifests, lockfile, Vite and TypeScript configs are byte-identical to the pinned commit. Only frontend sources, assets, docs and the art preparation scripts changed.

One note, not a finding. Running the typecheck on Windows fails because the pinned source already contains both LearningLab.tsx and learningLab.ts, which collide only on case-insensitive filesystems. This predates the overhaul, passes on the Linux build host, and is outside this work's scope.
