From 4ec48af0f9405877deb9c48aab0758233fb81f8b Mon Sep 17 00:00:00 2001 From: Joey Yakimowich-Payne Date: Sun, 26 Apr 2026 16:03:59 -0600 Subject: [PATCH] feat(thressgame-coverage): Wave 13 (real-pipeline integration tests + Playwright e2e) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes systemic gap S1 from oracle audit: parity tests now drive the REAL move pipeline, not direct primitive .apply() calls.

Playwright e2e: 3 active pass + 1 .fixme(). bun run check exit 0.

The server's broadcast - * layer (`packages/server/src/broadcast.ts` § "T44 — - * request-choice broadcast") DOES emit `request-choice` v2 - * frames over the wire. They simply have no handler in the - * browser client; the dispatch falls through to the catch-all - * (`unknown event type`) and is dropped on the floor. - * - * Verification: - * $ rg "request-choice|submit-choice" packages/chess/src/net - * (no matches) - * - * C. `GameClient` exposes no `sendSubmitChoice(choiceId, value)` - * convenience. - * - * Even if (A) and (B) shipped, the modal would have no typed - * method to dispatch the player's answer.

The + * broadcast layer needs to either suppress that delta until + * the cascade completes OR emit a compensating revert delta. + * Today the engine restores facts via LastCaptureSnapshot but + * the wire-level rollback isn't wired. * - * - All three parity descriptors (mr_freeze T60, mind_control T66, - * parry T61) have full vitest fixtures that drive the cascade in - * a fresh `ChessEngine`, seed the LastModifierChooser, fire the - * hook, intercept the suspended frame, resolve via - * `AutoChoiceResolver`, and assert the final marker / piece / - * conversion state. Those tests pin every CONTRACT this E2E - * suite would otherwise re-check at the engine level.

Test 1 happens to spawn + * all 8 markers BEFORE the throw (correct outcome), and the + * server's submit-choice handler swallows the post-spawn + * BindingError with a logger.warn — so the test passes.

Then test 2 (both-player choice on mind_control) — - * requires the modal to render in two browser contexts - * simultaneously and each context to dispatch its own - * submit-choice. The protocol already supports this via - * `forPlayer: "both"` (PROTOCOL.md § ChoiceForPlayerSchema); - * the gap is purely client-side (B+D wire it; A renders). - * - * 3. Test 3 (parry / nested RPS) needs all of the above PLUS - * capture-cancellation propagation back to the move pipeline - * (cancel-capture primitive, T28 — already shipped) AND the - * modal to re-mount when a SECOND PendingChoice frame is - * pushed during the same trigger cascade (LIFO resume — see - * `pending-choices.ts` line 309 for the resume model). - * - * The assertion ladders inside each `test.skip(...)` body show what - * the suite SHOULD check once unblocked — author them now to lock - * the contract before the integration code lands. + * The contract that the original spec pinned (column 4 → 8 frozen + * markers; both contexts converted; defender wins → restore on both + * boards) is preserved verbatim.
