Original prompt: I want to create a web app game engine that supports 'baba is you' dynamic rules and sokoban style with mods defined as commonjs modules. /Users/dami/game-dev-asset-packs has assets to use. I think we would stylize using emoji and text effects. Pretext might be useful to have text effects on the emoji, understand placement, etc to drive the grid well.
2026-09-23: Empty workspace. Building a browser game with a separate rule engine, emoji canvas renderer, and local CommonJS mod loader. Pretext will lay out variable-length UI copy; fixed grid cells remain independent of text metrics. Selected Kenney UI sound effects from the user's asset collection.
2026-09-23: Research inventory added at docs/design-backbone.md, drawing from creator interviews, GDC material, and Sokoban design literature. OpenSpec initialized for Codex; active change build-dynamic-rule-engine has proposal, four capability specs, design, and tasks. Git initialized on main with focused commits requested by the user.
2026-09-23: Engine, three teaching levels, CommonJS loader, UI, and audio assets implemented in parallel. The verified content set now contains nine proof levels across Core, Basic Proofs (stable internal pack ID garden-basics), and Word Lab. Sound and optional music controls are available from Pause. npm test and npm run build pass.
2026-09-23: Playwright browser checks pass for rule breaking, keyboard and touch movement, undo, reset, valid and invalid CommonJS imports, victory, and continuing to the next level. Inspected the rule-break and victory screenshots and the text game state; the rule table updates when STOP moves. Level 2's wall-rule shortcut was sealed and its intended push solution still passes. The designer requested richer settled turn events (E1/E2); source IDs and axes are implemented, and the event payload is receiving a final ordering/contact review before OpenSpec archival.
2026-09-23: E2 event review completed. Movement includes push provenance and contact-destroyed movers; rule deltas retain source IDs and axis; blocked events identify the physical blocker. E3 sentence spans are implemented and archived at openspec/: state.sentences preserves every maximal physical sentence with source IDs and axis while semantic rules deduplicate. E4 pack-service and pack-library operations are implemented and unit tested, including local import preview, explicit install, reload, export, sharing, replacement, forking, and removal. Local imports and shared URLs both enter the Gift preview and require Keep and play. Workshop exposes Import, Play, Share link, Export, and Remove. At this checkpoint, the stage and final public browser gates were still in progress. OpenSpec change build-dynamic-rule-engine was validated and archived.
2026-09-23: E4 is archived at openspec/. The S3–S10 full-screen stage is implemented in revision 2 at https://fcbc.n.zip/. Revision 2 passes 114 Node tests, 27 browser checks, and the production build, covering the stage scenes, input routing, sentence-bar juice, Workshop/Gift flows, audio fallback, local Recursive font, mobile, reduced motion, and ?dev. Designer round 2 approved the implemented chapter flow; visual P1/P2 changes remain in progress, so this status does not imply final visual sign-off.
2026-09-24: Revision 3 at https://fcbc.n.zip/ passes 144 Node tests, 36 browser checks against the public URL, and the production build. Player reports are fixed: a fresh presentation timeline on next-proof load, same-entity YOU + WIN after SINK/DEFEAT, visible-link INDEX arrows, and horizontal actor facing with undo history and mod opt-in. Title and INDEX now expose Workshop directly; mobile Workshop rows and action targets fit at 390×844. The same-entity win OpenSpec change is archived. The stage change remains active for designer round-3 copy, contrast, and settled-frame review.
2026-09-24: Public revision 4 fixes the round-3 visual findings: operator mini tiles display IS/AND, the Win progress line clears its headline, keycaps use key-first grammar, the mobile INDEX banner is readable, and Workshop's Import row is centered. The public build passes 145 Node tests, 36 browser checks with no console errors, and the production build. The designer accepted the stage visual gate. build-ink-signal-stage is archived at openspec/; all seven live OpenSpec capabilities pass strict validation, with no active changes.
2026-09-24: The public reduced-motion walkthrough passed at 1280×800 and 390×844 through Title, INDEX, Proof, Pause, and Win with no console errors or visible iris, shake, or particle artifacts. The shipped audio clip mapping was sent to the designer for a future mix-by-ear review.
TODO: Review the audio mix by ear and keep the spacing rule for future teaching proofs. New mechanic or campaign work should begin with a new OpenSpec change from the roadmap.
2026-09-23: Began add-rule-driven-automata for patterned emoji actors. The first slice uses declarative, turn-based patterns activated by a level-scoped word property (for example MOUSE IS TICK); the property may transfer to another noun when the sentence changes. Accepted movement or explicit WAIT advances one beat, while blocked player input and inactive rules hold the phase. Engine, CommonJS validation/sharing, and beat-strip UI are in parallel implementation. The designer owns final beat visuals through docs/; the worlds team has the property-carried contract in docs/. Current source edits are provisional and not yet committed or published.
2026-09-23: Rule-driven automata now pass 166 Node tests, the production build, strict OpenSpec validation, and 9 focused browser checks across desktop and 390×844 mobile. FENN 🦊 is the named example actor; the TICK beat strip, on-board action cue, optional sound, Space/mobile WAIT, Undo/reset phase, data-only sharing, and solver snapshot/phase support work. The unbundled mods/ remains a mechanics sample because the solver finds a bypass in 8 rightward moves; the Clockwork world is authoring a timing-dependent proof. Gates/occupancy plates and rule-driven one-step tiles are assigned to Crate Works and Tidewater respectively, with semantics pending scenario review in docs/.
2026-09-23: Public revision 7 at https://fcbc.n.zip/ preserves the existing nzip target and expiry (2026-10-23T23:16:58Z). Its focused desktop/mobile browser run passes 9 checks with no console errors. The final mobile WAIT control is labelled plainly and fits above Restart. The active automata OpenSpec change remains open for deterministic solver and visual fixtures, plus designer review of the final frames. The designer was asked to replace the old fox token in its owned reference docs and prototype with FENN.
2026-09-23: Public revision 8 corrects MIAU's intermittent backward pose. The proof renderer now recognizes the built-in 🐈 as native-left even through a same-glyph plain palette string, and every accepted horizontal displacement (including pushes) sets the actor's facing from travel; Undo/reset still restore prior/native direction. The FENN face emoji example is neutral. The new fix-miau-forward-facing OpenSpec change is strictly valid and complete after 170 Node tests, the production build, the existing browser flow, and the focused desktop/mobile facing flow against the public URL. Vertical moves retain the side-profile's last horizontal pose. The designer received the corrected D18 contract for its owned reference docs.
2026-09-23: Started the runtime architecture review and modularize-runtime-boundaries OpenSpec change. Read-only audits found stage action duplication, dense application turn orchestration, engine full-array lookups, repeated pack clone code, and minified CSS as the highest maintenance risks. docs/ records state ownership, boundaries, risks for gates/switches/crumble, and staged follow-up work. Pack data cloning is centralized in commit f014da5; CSS formatting is isolated in commit 2dfb250. Stage, app, and engine extraction slices are under integration review before their individual commits. The designer and world team files remain separately owned.
2026-09-23: Completed and archived modularize-runtime-boundaries. Stage is 648 lines (from 1,526), board renderer 432 (from 660), engine 378 (from 427), and INDEX progress is separate from map navigation. The app has dedicated turn, intent, and developer-view modules; juice has pure visual/effect projections; pack cloning has one data boundary. The browser loop found a missing proof-renderer import and stale engine indexes after Undo, both fixed and covered. Final local gates: 183 Node tests, Vite build, full share/campaign browser flow, automata desktop/mobile flow, death-Undo visual flow, inspected screenshots, and no console errors. OpenSpec strict validation passed all 11 active/live items. Stable public preview https://fcbc.n.zip/ is revision 9 (existing expiry retained). Next architecture work: geometry-derived pointer targets, further juice event-reducer split, unified mod/engine validation, mechanics-aware snapshots and solver keys, and an explicit automata conflict policy before gates/switches/crumble.
2026-09-23: The ongoing polish goal is active. W3 compact BFS and fast transitions now reproduce ten baseline routes and 150 per-action states exactly. Same-search RSS is 29.7–47.0% lower than the legacy full-state solver on three representative proofs. tools/ uses the compact fast path, with optional solverBudget, allowBypass, allowHandsOff, and mustForm author checks. The worlds team confirmed the field names; its packs and CI gate remain in progress. W6 Crossword rework remains with the worlds team. W11 diagnostics now recognize pack palette/vocabulary nouns such as Word Lab GEM and report cross-proof property/thing ambiguity; design's revised Gift/Workshop copy and mobile affordances are in local browser review. Public revision 10 remains the stable preview until that review passes. TODO: finish W11 visual browser acceptance, coordinate bundled-world budgets and CI, then update the public preview after design review.
2026-09-23: Design accepted W11. Revision 11 is live at https://fcbc.n.zip/ with its existing expiry and access policy; the public share/campaign browser flow passes without console errors. W11 is archived in OpenSpec after 278 Node tests, the production build, strict validation, and mobile Gift/Workshop warning screenshots. A nonblocking Workshop mobile keycap/CLOSE polish item is underway. The W3 CLI now honors an explicit --max above the 2M default; Tidewater shell-game --forbid 'JELLY IS SHELL' --max 3000000 genuinely reaches LIMIT after 3M attempts (223.47 s), so its mustForm remains unset. TODO: finish Workshop mobile polish, agree first bundled-world CI pack set and heavy solver budgets, then resume W6 Crossword content validation.
2026-09-23: The first W3 bundled-world gate is being implemented for core, Crate Works, Tidewater, and Clockwork. The worlds team confirmed those packs solve at the default 2M cap; core two-things-can-win will declare its intentional BYPASS. A bounded shell-game audit found no equivalent states to merge among 50,417 sampled states, so its unproven mustForm remains unset while the worlds team simplifies that proof. W6's PUSH/STOP precedence, X IS X, spatial transformation order, and bounded stacked-cell grammar are implemented; Crossword's carry-the-pair route now correctly loses under DEFEAT-before-WIN, and the worlds team has the content rework handoff. D22 Pause, Win, ledger, skid, HUD and an explicit ?slowmo=N presentation clock are committed locally under animate-stage-motion-language. Browser review found a selected Pause tile contrast bug and a clipped mobile hint; those are being corrected before design review. Revision 11 remains public until the designer accepts the new motion captures and Workshop mobile P2.
2026-09-23: W3's compact solver is verified and archived. The sequential Core, Crate Works, Tidewater, and Clockwork gate solved all 23 proofs in 794.86s without LIMIT or disallowed author warnings. The corrected core proof 02 now teaches unmaking ROCK IS PUSH: a straight push jams, the authored route removes the rule at step 8 and wins at step 26 in both solver and browser replay. D22 Pause and Win are accepted by design; their mobile hit regions and visible Pause gaps passed browser QA. Title, INDEX, Gift, and Workshop transitions are implemented and their desktop/mobile reduced-motion and slow-motion flows pass. The final keycap press capture exposed an unnecessary proof-to-proof iris on Undo/Restart, now under a focused fix. The designer and worlds team chose memoryless channel gates and stable-ID FRAIL leftovers; a strictly valid mechanic foundation plus separate gate and FRAIL OpenSpec changes record the contract before implementation. Revision 11 remains public until the final HUD and public browser gates pass.
2026-09-23: Public revision 12 at https://fcbc.n.zip/ ships the designer-accepted D22 motion language, clipped step odometer, Z keycap pulse, no-iris same-scene Undo, full-viewport player chrome, and shared ledger property colors. A late file-import scene race and an initially-won-proof scene race were found by the complete browser flow and corrected with focused regressions. D22 is archived as 2026-09-24-animate-stage-motion-language; all live and active OpenSpec items validate strictly. Final production and live-URL browser flows pass with no console errors, and the revised sequential world gate solves 23/23 proofs in 762.46s with shell-game's JELLY IS SHELL requirement and no solver warnings. The public alias, access, and expiry are unchanged. Next: close D21 beat-strip/title authoring polish, finish Crossword content convergence, then implement the validated mechanics lifecycle and codec before gate and FRAIL world proofs.
2026-09-24: W14 rules-revision compatibility is implemented and archived after designer copy approval. D20 now has world identity validation and W11 notes, one pack per INDEX world, per-world progress, Q/E/gamepad/two-finger navigation, cursor snapshots, first-entry/Workshop world cards, and approved local bundle order core/Crossword/Crate Works/Tidewater. Focused commits keep these units separate. The local 390px browser showed Title→core card→INDEX→Crossword card with no console errors. D21 next-beat strip fill and transferred BELL cue passed the blocked/transfer browser fixture. The designer-approved 64-character title ceiling and up-to-three-line mobile fallback passed Gift→INDEX→Proof→Win browser QA; the 51-character fixture uses two full-width 16px lines at actual font metrics. TODO: designer sign-off for D20/D21/title captures, complete multi-world share/Workshop browser gate, run full Node/build and sequential world solver after bundle, then refresh the stable public alias. Clockwork remains gated by W12 custom-property presentation. Architecture follow-up stabilize-active-level-identity is strictly valid but pending implementation.
2026-09-24: D20 is designer accepted and archived. Revision 13 at https://fcbc.n.zip/ adds the four approved default worlds, Core's authored 🐈 identity, the revised world cards and fixed INDEX presentation; the public desktop/mobile world-index flow passes with no page errors. The local Gift/Workshop/share flow, 373 Node tests, production build, and sequential 30-proof world solver gate pass. Clockwork remains outside the default INDEX pending W12/D21. Stable active-level IDs and direct catalog lookup are committed; a 64-level comparison measured 65.2× faster last-level reads than the previous full-list clone/scan path. The active-level OpenSpec retains one delayed-Win replacement/removal regression gate. A new strict-valid OpenSpec change, consolidate-level-schema-boundary, addresses direct-engine/CommonJS/share validator drift before gate and FRAIL runtime work. The goal remains active with the design and worlds teams through their inboxes.
2026-09-24: Public revision 14 at https://fcbc.n.zip/ ships the shared level-schema boundary and world-card accessibility follow-up. Direct games, trusted CommonJS packs, and data-only shares now normalize the same authored level fields and automaton shorthand, while catalog/Gift view metadata is stripped at the game boundary. Malformed input retains one structural issue code/path through caller-specific errors; unknown future mechanics fields fail explicitly. The full 388-test Node suite, production build, and sequential 30-proof world gate pass, including Clockwork's escapement. Both live-URL browser fixtures pass world-index and Gift/Workshop/import/share/Win/mobile/reduced-motion flows with no page errors. consolidate-level-schema-boundary is archived and its main capability spec is installed. The design/world team has delivered derived gate and FRAIL fixture drafts; FRAIL's leaves contract is being revised from per-object metadata to a level-scoped current-noun map before runtime work.
