Summary

The three engine defects are fixed and the new mechanisms are in. All 196 tests pass, including 13 new ones in tests/agency.test.js; the log is in docs/agency/results/test-run.txt. Some of the new mechanisms work in tests but did not show up in the simulations. Those gaps are listed below.

Engine defects (6–8), each with a test that reproduces it:

• 6, store contents seen from a distance: residents no longer learn what's in a store just by seeing the shelter. Only visiting it (deposit, retrieve, salvage, repair, or finishing the build) updates what they remember. Old memories stay out of date until they visit again, and residents are no longer offered "retrieve" for stores they've only seen from afar.
• 7, ruins: deposit and retrieve at a ruin now fail, and its contents are kept. Residents no longer treat remembered ruins as homes or stores. The contents can be recovered by repairing the shelter or with a new nearby "salvage" action. Views list ruins separately, so old clients don't draw them as homes.
• 8, build step showing idle: a newly chosen step now shows starting. A 1,500-tick check confirms idle appears only when a resident has no step at all.

New mechanisms, built on the existing planner and mb-v1:

• Object and material properties (capabilities.js) decide only which action a resident may try, not what happens.
• Plant/tend/harvest, limited by soil, temperature and water.
• Cooking that uses up fire fuel and converts food 1:1.
• Voluntary provisioning and repair of another resident's shelter. A resident only knows whose home a shelter is by seeing that person rest there, and helping has no built-in reward.
• Persistent goals (at most 4 per resident) that can be interrupted and resumed. A strategy that fails twice for a goal gets dropped for an alternative.
• Six neutral glyphs as local signals, with limited range and attention, and some misheard. There is no built-in reward for signalling, and credit to the sender is capped.
• Migration 4→5 was tested on a real schema-4 save (new fixture tests/fixtures/expanse-v4). Residents' identity data is unchanged, remembered store contents are kept as they were, the original bytes are preserved, and restart and rollback work. The owner's dry-run upgrade also passes.

Results (docs/agency/ENGINE.md, raw numbers in docs/agency/results/):

• The item count balanced exactly in all 14 runs (3 seeds × learning on/frozen × signals on/off, plus 2 runs with food depleted).
• With learning on, residents plant 4–19× more than frozen ones. But frozen populations grew slightly larger over 3,000 ticks, so learning doesn't help population here.
• Signals had no measurable benefit. The average payoff residents learned from responding to a glyph is about zero.
• No resident cooked in any run. Fires are rare: 2 lit in 8,000 ticks.
• No resident provisioned anyone naturally. Repair help happened 5 times in 8,000 ticks.
• Schema 5 uses about 1.9× the CPU per tick: 7.6 ms vs 4.0 ms at the median with 100 residents. I measured that on this x86 machine. The ARM VPS hasn't been benchmarked; the doc gives the command for the owner to run there.

Not done in this assignment:

• Defects 1–5 and all world-presentation work (animations, inspector panels, biome art). Those need changes in web/ and dist/, which are outside my allowed paths. The engine already sends the data the client would need, and old clients still work.
• No screenshots or recordings.
• The shipped demo still runs the schema-4 engine and needs rebuilding during integration.

All of this is also listed in the doc.

Delivered the updated isolated-engine demo and static export in dist/.

• Fixed five UI/rendering defects; revalidated three inherited engine fixes.
• Passed 234 tests, typecheck/build, 10 browser interaction groups and 16 design checks.
• Preserved the original checkpoint. Delivery adds 6.10 MiB; protected files unchanged.
• No production deployment.

Validation and resolution table · Build instructions

Safari/ARM remain unverified. Natural cooking and provisioning-help emergence remain unresolved.

Review complete. The export can be hosted: nothing critical or high was found. The findings file holds five advisory entries, and no repository file was changed.

What was read. Every file in dist/ that will be served: index.html, the main bundle and the demo worker bundle, the stylesheet, both config JSON files, the art manifest and all five WebP sheets, the two demo checkpoints and their manifests, the six licence files, the share image, logos and favicons. I also read the source they were built from (main, Router, expanse App, Map, Inspector, AgencyEvidence, transport, demo worker, art and renderer modules) and the engine files the worker bundles.

What the scripts do. The main bundle loads expanse-config.json, starts a module worker that fetches the gzip checkpoint, verifies its SHA-256 against the manifest, and runs the engine locally. The only outbound host is the owner's VPS, and only after a visitor presses Connect live, as a plain GET with credentials omitted. There is no eval, no dynamic import, no iframe, no redirect, no tracker, no wallet provider call, and no seed-phrase or key prompt. The checkpoints contain no addresses, paths or secrets. The art is the golden leaf-crowned species throughout. No third-party name, logo or franchise reference appears in the export, and the art licence states the OpenAI generation provenance honestly. The demo manifest hash matches the shipped checkpoint, and the bundle contains the current source strings, so dist is built from this tree.

Findings written to .imd-findings.json:

• Low: the hosted licence folder lists wagmi, viem, Coinbase wallet SDK, bip39 and ws as runtime dependencies, and ships a RainbowKit notice, though none of that code is in the bundle.
• Low: the static page still offers Connect live to the owner VPS even though its own README says the static origin cannot pass that server's CORS policy. The brief asks for unavailable features to be hidden.
• Info: web/package.json and web/src/wallet.tsx keep unused wallet dependencies and code that nothing reachable imports.
• Info: dist/world-config.json is published but never read by any hosted script.
• Info: the worker bundles the engine's visitor wallet bookkeeping, but its message handler accepts only start, pause and frame, so it is unreachable. Recorded as confirmation of no unintended wallet flow.

Not verified. I did not rebuild the bundle from source, since no node_modules are present and the time budget did not allow an install. I did not send any request to the owner VPS, so the CORS outcome of Connect live is inferred from the README rather than observed.

Review complete. Findings are in .imd-findings.json at the repository root. No tracked files were changed.

What I verified against the final tree

• All 61 tests in the agency, regression and repair suites pass under Node 22.
• Defects 4 to 8 are fixed in code: the repair pose maps the emitted repair phase with tool and material gates, the Settlements panel heading is correct, sight records shelter appearance only and stock is copied only on visit, ruins deny deposit/retrieve/protection and preserve contents with repair or nearby salvage as recovery, and a step without a phase reports starting.
• Defects 1 to 3 have tests and screenshot evidence: safe-area CSS and a reachable close button in the landscape phone capture, focus-clamped camera with corner tests, and visible cliff faces and heights in the highlands capture. I did not run a browser myself, so these rest on the delivered captures and unit tests.
• Item ledger conservation holds in the recorded ablation runs and in my own reruns.

Findings, ranked

• Medium: frozen mode is not frozen for signalling. A seed 3 frozen run with communication on still accumulated 82 association updates, 153 co-occurrence counts and 291 avoid-list entries while the outcome model stayed empty. The frozen arm of the communication comparison is therefore contaminated.
• Medium: two of the three required chains never happen in engine-driven runs. Cooking and voluntary provisioning are zero in every recorded ablation row, the 8000-tick run, and my reruns. Only unit tests exercise them. The engine docs disclose this honestly, but the chains should be listed as not demonstrated rather than counted.
• Low: the social goal closes after one interaction, so it churns hundreds of times per run and crowds the bounded goal history.
• Low: stale wallet attribution in the shipped licence notices and web/package.json, merged from the specialist findings and reproduced.

Specialist findings about the Connect live button and unused config files were not reproduced in a browser within the time available and were left out.

Saved five reproducible findings to .imd-findings.json. The eight documented fixes pass the tested regressions; these additional defects require revision.

The report contains exact source citations, reproduction steps and proposed changes. Implementation files remain unchanged.

Independent verification passed: 17 targeted engine/migration/replay tests, 34 client tests, TypeScript, production build, ten browser interaction groups and sixteen exact corner pointer checks. Rebuilt assets match the submitted export byte for byte. WebKit remains unverified. Natural cooking and provisioning remain unobserved in the supplied ablation, although their functional tests pass.

Now let me look at view.js, persist.js, and the docs to understand what the inspector exposes and how migration works.Let me look at the docs that report the ablation results and the reproduction scripts.The docs already disclose the cooking/provisioning gap. Now let me set up the scratch reproduction scripts for the findings.Finding 1 reproduces exactly ([0, 0.52], [0, 0.12], [0, 0.12]). Now finding 2.The credit didn't fire because the receiver's wellbeing gain was negative in my staging (hunger rose vs. arrival). Let me fix the staging so the gain is positive, matching the finding's setup.Both high findings reproduce. Now the advisory findings in one script.All findings reproduce. Summary of my assessment:

• e1c07920 (carry reward loop): real — [0,0.52],[0,0.12],[0,0.12], and observers would learn it.
• e20258fa (omniscient sender credit): real — sender 12 tiles away got +0.5 model weight and 0.3 sent credit.
• c34b8f96 (frozen still learns associations/avoids): real — n=82, seen=153, avoid=291 with model=0.
• ba2d1ee7 (curiosity dead at cap): real — metric stuck at 96 after 10 novel cells.
• af7d9fb3 (share overfills): real — recipient went 12/12 → 13.
• 9b775dda (social churn): real — 337 achieved vs 98 curiosity.
• 8f9bd31d (cook/provision never emerge): factually true but already disclosed verbatim in ENGINE.md "Known gaps"; I'll dispute that one.

Now the fixes. First engine.js — carry as transfer, share capacity check, settleWatch locality + frozen gating, onRespond gating.Now update perceiveSignal in agency.js to return conf, fix learnGoal/satisfied/goalMetric/ensureAgency, and markVisited in agent.js.Now add signalsFeedback to schema5Totals for telemetry, and check nothing else needs it.Both fixes verified: carry loop now gives [0, 0.4], [0, 0], [0, 0] (only one-time novelty, same as store transfers), and the out-of-range sender gets no credit. Now verify the positive path — a nearby sender should still learn via the feedback signal.The ack was emitted and heard but misheard ('◇'→'□'), so no credit — honest misperception. Let me verify credit does flow when heard correctly, across a few seeds.The feedback path works end-to-end: heard correctly → credit (seeds 3, 17); not attended → nothing (7); misheard → nothing (11). Now verify the advisory fixes.All advisory fixes verified. Let me check for any other code reading visited.length for curiosity, and confirm no other transfer-reward paths remain.All production/transfer sites are correct now. Let me check whether existing tests touch carry, signal credit, or share behavior that might be affected.Existing tests are compatible. Now let me check the ablation experiment script so I can refresh the documented results after the behavior changes.Now I'll add the regression tests to tests/agency.test.js.Fix the dynamic import in the curiosity test — import ensureAgency statically instead.One test issue: stage() books staged items into totals.gathered, so I should compare before/after the cycles instead.While that runs, update the docs. First the signalling section in ENGINE.md.Now add a resolution section for this revision's findings, after the existing defect table.Two restart/determinism tests failed. Let me look at that test and diff the state to find what doesn't round-trip.The diffs are huge — let me reproduce the restart test in scratch and diff the states field by field.Only the chunks key differs — no creature diffs. Let me diff chunk-by-chunk to see if it's membership or content.The divergence is behavioral — a node emptied at t=398 in the uninterrupted run wasn't emptied after restart. Let me check if this test fails on the pre-change baseline by stashing my edits.Baseline passes — my change broke restart determinism. Let me check the Rng implementation and hunt for what doesn't round-trip.Rng is a single uint32 — fine. Let me bisect: compare in-memory states at tick 400 (determinism) vs after reload.States are

I fixed the medium finding and answered the low advisory as disputed. Both responses are in .imd-responses.json. While rebuilding I also found and fixed two problems I wasn't asked about. Nothing is committed or deployed.

Finding 26cec351 (medium): fixed

• Reproduced on the committed export. At 844×390 the inspector kept the roster's scroll position (47 px) and resident #154's name was entirely above the visible panel. At 320×568 it was 75 px and the whole identity block was hidden. Portrait 390×844 and 1440×900 were not affected.
• Cause: the roster and the inspector share one scroll container, and the new heading is focused without scrolling to it.
• Fix (web/src/expanse/App.tsx): switching panel or resident now resets that container to the top before the heading gets focus. When the same inspector refreshes, the reader keeps their place.
• Test: new check web/scripts/check-inspector-scroll.mjs. It passes at 844×390, 320×568, 667×375, 390×844 and 1440×900: scroll starts at 0, the whole name shows, the heading has focus, a 120 px refresh scroll is kept, and there are no console errors. Results and two phone screenshots are in artifacts/agency-interface/.

Finding d3e8c3f0 (low, advisory): disputed, with a clarifying note

• The observation is correct: none of the wallet libraries are in the hosted bundle.
• I can't remove them from web/package.json: the task rules reject any submission that touches it. The old wallet client (Legacy.tsx, wallet.tsx) also still imports them, so removing them would break the typecheck.
• Instead, the license notices now say these packages are declared for the legacy wallet client and none of their code ships in assets/.

Problems found and fixed during the rebuild

• The build failed on a fresh machine. The helper web/scripts/task.mjs didn't copy shared/ into its temporary build tree, but the client imports shared/relief.js. It now copies it.
• The committed export was older than its source. The engine job merged after my last round (commit b702f51) changed the simulation engine, so rebuilding put that new engine into the export. That made 1 of 206 server tests fail: the demo checkpoint could no longer be reproduced exactly. I hadn't touched any of the files that test covers; the engine change caused it.
• Demo regenerated. I re-ran the documented recipe (tools/living/upgrade-demo.mjs: the original checkpoint plus 600 ordinary ticks, nothing injected). It produced exactly the hash the test had computed on its own. The original checkpoint is unchanged byte for byte, and the demo now has 168 residents, including #154 (Ziye).

Results after the final build

artifacts/agency-interface/VALIDATION.md has the full finding table and these commands; README and DESIGN.md are updated to match.

Not changed or still unverified: package.json and the lockfile are untouched. Older artifact records still cite the previous demo hash, and the validation file explains the difference. Safari/WebKit, real phones and the ARM server remain unverified, as before.

The review is settled and written to .imd-findings.json with three entries. No tracked file was changed. Nothing critical or high was found, so the site can be hosted.

Hosted export read this round. index.html, both minified bundles, the stylesheet, the config and manifest JSON files, the SVG logos, and every licence file. The bundles contain no wallet provider calls, no iframes, no eval, no silent redirects and no external code loads. The only external URL is the owner's own server.

How each earlier finding settled:

• Connect live on a static origin (low) stays open. The control is unchanged at web/src/expanse/App.tsx:520. I probed the owner server with the hosted ENS gateway origin and it returned no access-control-allow-origin header, so every visitor sees the "unavailable from this origin" notice. Advisory only, read-only GET, no secrets.
• Wallet-library notices (low) is fixed with residue, downgraded to info. The notices file now discloses that the wallet packages belong to the unreferenced legacy client. The dependencies.json list and rainbowkit.txt still attribute code and marks that are not in the export. Harmless.
• Unused source wallet dependencies (info) dropped. The author's reason holds: package.json is protected in their assignment and the legacy modules are in the TypeScript include set. Nothing hosted.
• Stray world-config.json (info) dropped. The project's own preflight script asserts that file, so it is deliberate, not stray.
• Engine wallet bookkeeping in the worker (info) kept as a verification note. The rebuilt worker still carries one dead engine string, and the worker handler still accepts only start, pause and frame.

One limit. Playwright is not installed on this machine, so the Connect live click was confirmed by the CORS probe and the bundle source rather than a browser session.

All five previous findings are fixed. [.imd-findings.json][findings] contains {"findings":[]}. No new reproducible defect was found.

Validation passed: 23 agency/view/demo tests, 34 client tests, TypeScript checking and production build. All 27 rebuilt export files match the committed export byte for byte. Browser checks covered five viewports; all four corner tiles were reached and picked at three viewport sizes.
