 - CoA specializations and RoM class/role builds are Needs Testing. They may be inspected in an explicit targeted diagnostic, but must not enter random, all-eligible, regression, bracket, or NPC seat-audit runs.
 - A broader balance run requires an explicit user request or a readiness-policy promotion. Record that expanded scope in the task handoff.
 
+## Default test dungeon
+
+- Use **Stormwind Stockade** (`stormwind-stockade`) for new routine gameplay,
+  mechanics, healing, party, camera, input, performance and browser diagnostics.
+  This is the project owner's default as of 2026-10-04. Use the full dungeon,
+  rather than its Bite-Sized or randomized variants, unless that mode is the
+  subject of the task.
+- Shared playtest defaults belong to `scripts/playtest-defaults.cjs`; the current
+  workflow and evidence requirements are in `docs/TEST_DUNGEON_POLICY.md`.
+  Install/verify the Stockade content pack through the normal entry flow when
+  needed. Bundled starter content is not a reason to select Wailing Caverns.
+- Do not choose Wailing Caverns for new routine live tests. Retain its existing
+  source-specific unit/import fixtures and historical reports as evidence, but
+  they do not override this default. A new Wailing live run requires an explicit
+  user request for that dungeon.
+- Preserve incident-specific historical evidence from other dungeons. When
+  investigating a report tied to another dungeon, inspect that exact source;
+  use Stockade for generic validation and follow the user's requested dungeon
+  for any separately authorized encounter-specific reproduction.
+- This fixture choice does not promote Needs Testing builds, broaden balance
+  certification, change the level-80 cap, or authorize loot wiring.
+
+## Mechanic subprocess preference
+
+- When delegating the owner's mechanics work, use `gpt-6-luna` with `xhigh`
+  reasoning by default. A higher-tier subprocess model requires the owner's
+  explicit permission; do not silently upgrade because a task is difficult.
+- Divide independent mechanics where practical, coordinate shared runtime files
+  and the production build, and keep user updates brief.
+
 ## Playable characters and equipment
 
 - `src/avatar/CharacterModel.tsx` is the shared player, party, roster, and character-creation rendering path. Never replace it with a screen-specific loader.
