+# tests/PLAN.md — combat-hud-hub
+
+## What we test
+
+**Smoke (no-Foundry):** `verify-combat-hud-hub.mjs`
+- Sections A-K: module skeleton, section registry, feed entries, soft-dep behavior, hook subscription, render loop, public API integrity, ApplicationV2 surface, throttled render, section render context, unwire.
+- Section L: current-turn indicator (v0.2.1).
+
+**Playwright (live Foundry v14):** `verify-combat-hud-hub-foundry.mjs`
+- 1. Join as Gamemaster (or Player fallback).
+- 2. mod.api surface (8 documented methods + version).
+- 3. Soft-dep presence detected for hooks-lib, battle-focus, its-achievable.
+- 4. Core sections register iff battle-focus present; hide gracefully otherwise.
+- 5. its-achievable registers pinned-achievements section iff it's installed.
+- 6. addSection / removeSection round-trip via live API.
+- 7. pushFeedEntry delivers entries to render ctx (live array reference).
+- 8. HUD opens via api.openHud (.chh-hud in DOM after combatStart).
+- 9. Core section rendering: round counter, current turn, combatants list, dice streak.
+- 10. Current-turn indicator: exactly one row has data-chh-current-turn="true".
+- 11. Screenshot of HUD for visual sign-off.
+- 12. No thrown errors during init/ready (pageerror events).
+
+## Threshold for "done"
+
+- Smoke: 46/46 passing in <2s.
+- Playwright: row 7 (FULL install) hits 100% on assertions 1-12.
+- Matrix driver (separate file, deferred): all 16 cells behave as documented.
+
+## Verify commands
+
+```
+npm test                  # smoke
+npm run test:foundry      # Playwright
+```
+
+Prereqs for Playwright:
+- Foundry running on localhost:30000 with the "Hello World Demo" world.
+- combat-hud-hub installed in Data/modules/ and enabled in the world.
+- foundry-hooks-lib + battle-focus + its-achievable installed and enabled (for full-install assertions; tests skip gracefully if any are missing).

+// tests/verify-combat-hud-hub-foundry.mjs
+//
+// Playwright + live Foundry v14 test for combat-hud-hub v0.2.1.
+// Verifies the things the no-Foundry smoke test CAN'T:
+//
+//   1. The hub loads cleanly in a live Foundry v14 world.
+//   2. mod.api is set on game.modules.get("combat-hud-hub") with the
+//      documented surface (addSection, removeSection, pushFeedEntry,
+//      listSections, getHud, openHud, closeHud).
+//   3. Soft-dep wiring: foundry-hooks-lib + battle-focus installed and
+//      active → core sections register automatically.
+//   4. Soft-dep degradation: foundry-hooks-lib missing → no subscription;
+//      battle-focus missing → no core sections.
+//   5. The HUD opens on combatStart, renders round + current turn +
+//      combatants with the current-turn indicator on the right row.
+//   6. Pushed feed entries land in the section's render context.
+//   7. Consumer-registered sections (its-achievable's pinned-achievements)
+//      render alongside the core sections.
+//
+// Run: `node tests/verify-combat-hud-hub-foundry.mjs`
+// Gate: passes before release.
+//
+// Prereqs:
+//   - Foundry running on FOUNDRY_URL (default localhost:30000).
+//   - combat-hud-hub installed in Data/modules/ AND enabled in the world.
+//   - foundry-hooks-lib + battle-focus + its-achievable installed and
+//     enabled (for the full-install assertions). Tests skip gracefully
+//     if any are missing.
