+Random parties and unselected filler seats use the declared default profile;

+future link at low levels), then consumes later links if talent points remain;
+level 80 starts from the level-80 link. Profile metadata records the applicable
+source point count, ranks retained after mapping to the imported Healer Man

+## Local graphical runs
+
+On Windows, double-click `scripts/Launch Balance Lab GUI.cmd`. The launcher
+starts the local Balance Lab service, opens the existing Balance Lab screen in
+the default browser, and keeps the worker service alive in its command window.
+Leave that window open until queued simulations finish. The equivalent terminal
+command is:
+
+```powershell
+npm run balance:gui
+```
+
+This development-only mode binds Vite to `127.0.0.1`, accepts API requests only
+from the loopback interface, and does not require an online account or GM login.
+It uses the same Python controller, TypeScript combat runtime, configuration
+form, progress UI, report dashboard, and artifact downloads as the server GM
+tool. Job history and reports persist beneath
+`artifacts/balance-lab-gui-runtime`; closing the browser does not stop work, but
+closing the launcher does. Production and ordinary development modes do not
+expose these unauthenticated local routes.
+
+Use **All brackets** in the GUI for every-10-level, every-5-level, or every-level
+runs. Use **Run locally** for one level. The runtime status at the top confirms
+that Python is available before a run is submitted.
+
 ## Repeatable command-line runs
 
+Run the same every-10-level schedule used by the GM screen entirely on the
+local development machine:
+
+```powershell
+npm run balance:lab:brackets
+```
+
+The bracket runner launches the existing Python controller and live TypeScript
+runtime; it does not contain a second combat implementation. By default it
+tests every WoW specialization at levels 1, 10, 20, and so on through 80, uses
+three seeds, allows 80 seconds per fight, and runs up to four level processes
+concurrently. Normal Balance Lab options can narrow the run:
+
+```powershell
+npm run balance:lab:brackets -- `
+  --levels 40,50,60,70,80 `
+  --simulations-per-party 5 `
+  --boss "stormwind-stockade/entry-1717" `
+  --boss "stormwind-stockade/entry-1663"
+```
+
+Use `--step 5` or `--step 1` for the other GM schedules, `--jobs 1` when the
+machine should remain responsive, and `--output-dir <path>` for a stable
+comparison location. `npm run balance:lab:regression -- <options>` runs the
+same suite but returns a failing exit code when configured pressure or
+durability limits are exceeded. The default checks flag boss durability below
+20 or above 70 boss-damage seconds, bracket-to-bracket boss-health growth more
+than 1.5 times party boss-DPS growth once the preceding bracket reaches that
+minimum window, missing incoming damage, and local raw runs where healers are
+not required often enough or answer fewer than 60% of five-second pressure
+windows.
+
+The bracket root contains `bracket-summary.json`, `.csv`, and `.md`. These show
+boss health beside direct boss DPS, incoming DTPS, effective healer HPS,
+mitigation, healing coverage, five-second pressure windows answered by healer
+throughput, outcomes, and growth relative to the previous tested level.
+`heirloom-summary.json` and `.csv` record the resolved item level,
+slot count, attributes, ratings, armor, and weapon DPS for every tested build.
+Existing reports can be re-analyzed without rerunning combat:
+
+```powershell
+python scripts/balance_lab_brackets.py --analyze-existing artifacts/balance-lab-brackets/<run>
+```
+
+Balance Lab builds use the `virtual-heirloom` preset. Empty persisted inventory
+and equipment assignments mean that no earned drops override the virtual set;
+they do not mean that the character is ungeared. Virtual heirlooms fill every
+compatible slot with specialization-specific synthetic stats, scale through
+level 79, and remain at item level 79 for every party member at level 80. They
+are not literal Blizzard heirloom item templates: their custom stat budget is
+normalized slightly above the best compatible same-level item in the authored
+WotLK-derived loot catalog. The saved catalog and heirloom summary make that
+resolved loadout explicit for each local run.
+
+Run selected brackets as a companion-only seat audit:
+
+```powershell
+npm run balance:lab:npc-audit -- --levels 20,40,60,80 --simulations-per-party 1
+```
+
+NPC raw rows include the named talent build and character, selected rotation
+profile/rule/reason counts, profile priority for every available ability,
+missing profile actions, GCD uptime, and sampled resource starvation/capping.
+Use these diagnostics before changing class coefficients.
+
+## Companion cooldown policy
+
+GM Tools includes a revisioned **Companion cooldown policy** editor. Generic
+rules control normal defensive, emergency defensive, healer mitigation, and
+major offensive cooldown thresholds. Mechanic rules bind an authored boss
+attack to tank-only or party-wide pre-emptive mitigation with configurable lead
+time and minimum defensive cooldown length.
+
+Clients load the published policy from `/api/companion-cooldown-policy`; GM
+reads/writes use `/api/gm/companion-cooldown-policy`. Server Balance Lab jobs
+snapshot the published policy before launch. Local runs use built-in defaults
+unless `--cooldown-policy` points to a JSON policy file.
+
+## Companion specialization readiness
+
+The shared revisioned readiness policy classifies all 31 WoW specializations
+as Ready, Beta, or Needs Testing. Shipped defaults certify only Protection
+Warrior/Aldren, Discipline Priest/Quorin, Marksmanship Hunter/Liora, Fire
+Mage/Xavian, and Assassination Rogue/Orin. The main menu, Dungeon setup, and
+Balance Lab link to the full Companion Readiness catalog. Players can inspect
+it; authenticated GMs can edit and atomically publish the complete policy.
+Published policies must retain at least one Ready tank, one Ready healer, and
+three distinct Ready damage specializations.
+
+Random and all-eligible WoW runs use Ready specs by default. **Include Beta
+Specs** adds Beta specs and is saved per device; explicit targeted runs may
+still select a Needs Testing spec, but their filler seats come only from the
+eligible Ready/Beta pool. CoA and RoM Balance Lab catalogs are unchanged.
+Server jobs snapshot the published policy and beta choice. Local GUI runs use
+the revisioned loopback policy saved under
+`artifacts/balance-lab-gui-runtime`; corrupt or missing policy files fall back
+to shipped defaults.
+
+CLI parity is available through `--include-beta-specs` and
+`--companion-readiness-policy <json>`. The JSON may be the published envelope
+or its policy config.

 - **Unsupported:** the catalog has only `unsupported`, `scripted`, or noncombat `utility` payloads, or represents a noncombat summon such as a scouting eye, ritual object, portal, or mount. These remain player-visible when valid but are deliberately excluded from autonomous rotations.
 - **Rotation defect:** an executable learned ability with combat semantics that cannot be selected in its valid state. Profile-reference tests, shared-policy scenario tests, party damage audits, and the expanded-class audit treat these as failures.

+## Companion readiness gate
+
+The shared WoW NPC policy begins with Protection Warrior (Aldren), Discipline
+Priest (Quorin), Marksmanship Hunter (Liora), Fire Mage (Xavian), and
+Assassination Rogue (Orin) as Ready. Every other WoW specialization begins as
+Needs Testing; Beta is an explicit GM-published opt-in. Readiness filters only
+NPC seats. Player character choices, RoM parties, and CoA/RoM Balance Lab
+catalogs are unrestricted.
+
+Ready is a certification result, not a tuning label. Its profile must resolve a
+legal Playerbots-derived talent allocation and learned ability ranks at each
+level bracket; preserve its generated identity, resources, gear, and precombat
+setup; execute every conditionally required action; react correctly to threat,
+healing, dispels, interrupts, movement, and boss mechanics; and demonstrate
+major offensive and defensive cooldown decisions without unexplained idle
+windows. Stock abilities whose Talent.dbc node was removed by the patched
+client (currently Devastate, Shadowstep, and Lava Lash) use their retained
+Spell.dbc source level rather than an impossible dangling talent gate.
