+## 2026-09-12 - Stockades party routing and indoor lighting
+
+- Fixed quantized navigation preparation: normalized integer positions now
+  expand to floats before the GLB node transform is baked. Previously the
+  Stockades world coordinates clamped into roughly [-1, 1], leaving the live
+  party unable to attach to its graph even when an offline route test passed.
+- Added three reviewed bidirectional links across the 1.537m Recast seams at
+  the entrance/central stairs and the central/north and central/south stairs.
+  The shipping 3,538-triangle graph connects the entrance and all five boss
+  approaches while discarding the remaining small decorative islands.
+- Added navigation-only review state and compiler-preserved runtime overrides.
+  Stockades navigation is green; its wider encounter, wipe/reset, checkpoint,
+  and completion validation remains unvalidated.
+- Leader and follower formation paths now use the graph when a breadcrumb
+  rejoin is blocked. Fallback comfort goals and recalls attach to the reviewed
+  surface, preventing an off-boundary stair target from causing a false stuck
+  loop. Combat approach connectors respect each member's personalized range.
+- Replaced the generic dark expansion palette only for Stockades with warmer,
+  stronger ambient/hemisphere fill and a warm directional light. No dungeon
+  textures or source meshes were changed, and other dungeon palettes remain
+  unchanged pending individual visual review.
+- Live desktop browser check at 1280 x 720 used offline level-15 Priest
+  Rolecheck as healer with Blood DK tank Morvane, Combat Rogue Vale, Unholy DK
+  Thorne, and Frost Mage Ilyra. Fresh Defend mode showed PARTY 5/5, Recall on the
+  entrance stairs recovered without a route warning, and Attack resumed with
+  visible party movement down the stairs. The tank advanced into combat and
+  took Defias Basic Attack/Kick/Backhand aggro; Backstab and Icy Touch events
+  appeared while the player remained at the entrance.
+- Inline task screenshots captured the warm, readable stonework/stairs and
+  equipped party silhouettes in Defend and Recall-to-Attack states. The final
+  runtime produced no new navigation errors; the existing deprecated physics
+  initialization warning remains. Temporary diagnostic logging was removed.
+- Automated validation: all 223 Vitest files passed, 1,373 tests passed, and
+  six existing tests remained skipped. Regressions cover the actual quantized
+  Stockades GLB through the shipping asset-preparation path, normalized integer
+  transforms, formation projection, entrance-to-boss routing, and tank melee
+  approach. This is an entrance/combat smoke pass, not a complete dungeon clear
+  or physical Android test.
+- Production TypeScript/Vite build, texture/performance audits, bundle
+  verification, and the final release candidate check passed. Existing
+  bundle-size/import advisories remain. No hosted release was published.
+- The optional all-dungeon functionality audit was stopped after an extended
+  run without output; its existing report files were not changed. Stockades
+  navigation evidence comes from the actual shipping-asset regressions and
+  the live smoke pass above, not a new fleet-wide functionality certification.
+
+## 2026-09-12 - Stockades stair-ramp follow-up
+
+- Follow-up player feedback reported companions still sticking near stairs.
+  Actual collision profiles contain approximately 0.44-0.59m risers, above
+  the party sweep's 0.32m lower-leg clearance. Collision-backed regressions
+  reproduce uphill rejection on the original shipping collision GLB.
+- Added three reviewed package-space traversal proxies for the entrance and
+  both prison-wing stair flights. Collision tread/riser vertices within the
+  reviewed stair relief are reshaped onto smooth ramp planes; upper walls,
+  ceilings, other floors, and geometry outside those footprints remain intact.
+  Source visual/collision GLBs are unchanged. Only prepared walking collision
+  and party navigation use the overrides; the rendered stairs remain steps.
+- Navigation receives the same ramp planes with 0.05m surface clearance and
+  six new triangles stitching the exact source boundary portals. This replaces
+  the three vertex-only connections with filled triangle corridors, allowing
+  mid-stair replans and recalls to project onto the interior walking surface.
+  The reviewed graph now has 3,544 source triangles and 31 components, retaining
+  entrance-to-all-five-boss routes and discarding minor decorative islands.
+- Live QA caught a second issue: terrain queries included the player's
+  kinematic capsule. A failing collision-backed regression confirmed false
+  route blockage through a nearby player. Party direct, route, and grounding
+  queries now exclude dynamic/kinematic actor bodies and sensors; crowd spacing
+  remains a separate party-separation concern. Static walls still block paths.
+- Automated tests exercise shipping normalized/quantized GLBs through runtime
+  preparation, downhill/uphill party capsule checks on all three flights at
+  center and lateral offsets, repeated mid-stair replans, all boss routes with
+  live wall checks, tank melee approach with real collision validation, and
+  player capsule traversal down/back up all three ramps without jumping.
+- Final desktop browser smoke pass at 1280 x 720 used offline level-15 Priest
+  Rolecheck and the same Blood DK/Combat Rogue/Unholy DK/Frost Mage party.
+  Attack began without ROUTE BLOCKED, companions changed position down the
+  entrance staircase, the tank moved out of the entrance view and took aggro,
+  and Backstab/Icy Touch/Plague Strike combat events appeared. Experience rose
+  from 6,576 to 11,098 as the party defeated trash with the player stationary.
+  Recall brought companions back to the entrance stairs. The unattended tank
+  eventually died during continued combat; this was not a healed full clear.
+- Inline task screenshots captured the unchanged visible steps, equipped
+  character bodies, warm lighting, and party movement. Both wing flights have
+  collision-backed automated coverage; live end-to-end wing traversal, a full
+  dungeon clear, wipe/checkpoint behavior, and physical Android QA remain open.
+- Validation: all 224 Vitest files passed, 1,380 tests passed, and six existing
+  tests remained skipped. Production TypeScript/Vite compilation passed using
+  the project's 8GB heap setting; texture/performance audits, static bundle
+  compression, and release-bundle verification passed. Existing build-size
+  advisories and deprecated physics initialization warnings remain. No hosted
+  release was published.
+
+## 2026-09-12 - Non-blocking players and combat actors
+
+- Removed party soft separation and crowd-triggered combat repositioning.
+  Companions may overlap or cross one another without push-apart corrections
+  changing their routes. Normal follow formations and role-specific attack
+  ranges remain; a tank already in melee range does not move just because an
+  ally occupies the same position.
+- Added a shared actor collision layer that interacts only with physical
+  terrain. The player capsule uses this layer. Player controller movement,
+  ground probes, camera sweeps, party direct/route validation, party grounding,
+  and combat ground-position queries use terrain-only filters. Actor body type
+  cannot turn an actor into a floor or movement obstruction. Party members,
+  remote players, mobs, and bosses currently render without physical colliders;
+  any future actor capsule must use the shared actor layer.
+- Walls, floors, ceilings, dungeon objects, and the Stockades walking ramps
+  retain their terrain collision. Target-selection meshes, combat visibility,
+  damage, and attack-range checks were not removed.
+- Ten new Rapier regressions cover overlapping actors with no contacts or
+  displacement, movement through fixed/kinematic/dynamic actors (including an
+  overlapped starting position), continued wall/floor collision, and ignoring
+  actors in ground, party-route, and camera queries. A terrain-layer control
+  confirms real actor/terrain contacts are still detected. Stockades shipping-
+  asset regressions now use the live player collision policy and still pass
+  down/up all three ramps without jumping.
+- Browser smoke pass at 1280 x 720 used offline level-15 Priest Rolecheck with
+  Blood DK, Combat Rogue, Unholy DK, and Frost Mage companions. Inline roster
+  and dungeon screenshots show character bodies, weapons, unchanged visible
+  stairs, and the existing warm lighting. Attack moved companions down from
+  the entrance and out of its view without ROUTE BLOCKED; the tank took aggro
+  and melee/caster combat events continued. Experience rose from 11,098 to
+  13,359. Stop followed by Recall returned the party to the nearby player.
+  Selecting Morvane and casting Power Word: Shield applied the buff successfully.
+- Live QA was an entrance/trash/recall smoke pass, not a full dungeon clear or
+  a manual traversal of both wings. Actor overlap and passage guarantees are
+  backed by the physics regressions; physical Android and multiplayer QA remain
+  open.
+- Validation: all 225 Vitest files passed, 1,390 tests passed, and six existing
+  tests remained skipped. The final focused checks passed again after cleanup.
+  Production TypeScript/Vite build, texture/performance audits, static bundle
+  compression, and release-bundle verification passed. Existing chunk-size
+  advisories and deprecated physics initialization warnings remain. No hosted
+  release was published.
+
+## 2026-09-12 - Individual companion navigation recovery
+
+- Replaced the old distant, whole-party stuck Recall with an individual
+  navigation watchdog in a separately tested game module. Two seconds without
+  meaningful waypoint progress invalidates that companion's route; five seconds
+  requests a safe recovery landing. Failed replans do not restart the timer,
+  back-and-forth movement cancels forward progress, and dense waypoint chains
+  still count genuine movement around corners.
+- Recovery prefers a recently visited party/player trail point near the group
+  on the same floor, then falls back to a validated player position. Actual
+  terrain checks require walkable ground, clear companion body space, and a
+  route back to the group. Blocked or invalid landings are not applied. Each
+  companion has an independent ten-second teleport cooldown.
+- Intentional attack-range holds, casting/channeling, crowd control, Stop,
+  death, inactive simulation, and UI pauses do not accumulate stuck time.
+  Automatic recovery changes only the affected companion's position and routing
+  state; it does not heal, resurrect, reset threat, or teleport other companions.
+  Manual Recall keeps its existing whole-party behavior and party order.
+- Added regressions for recovery timing, oscillation, replanning, independent
+  cooldowns and member isolation, exclusions, safe-trail/player selection, wall
+  and ceiling rejection, missing floors, and actor-independent landing checks.
+  Shipping Stockades navigation/collision assets validate recovery landings on
+  all three ramps and along approaches to all five boss objectives.
+- Browser smoke pass at 1280 x 720 used offline Priest Rolecheck and Blood DK,
+  Combat Rogue, Unholy DK, and Frost Mage companions. Inline roster and dungeon
+  screenshots show unchanged character bodies, equipment, stairs, and warm
+  lighting. The first catalog load needed a retry. Attack moved companions down
+  from the entrance without ROUTE BLOCKED, and combat continued with the player
+  stationary. The unattended party eventually died; Stop remained selected
+  after Recall returned the fallen companions without resurrecting them.
+- The intermittent side-room trap and its automatic recovery were not reproduced
+  live. Recovery triggers and terrain safety are backed by automated tests;
+  extended side-room playtesting, a healed full clear, and physical Android QA
+  remain open. This pass did not modify existing ramp or actor-collision policy.
+- Validation: all 227 Vitest files passed, 1,416 tests passed, and six existing
+  tests remained skipped. The final 37 focused checks passed after correcting a
+  test-helper type annotation. Production TypeScript/Vite compilation, texture
+  and performance audits, static compression, and bundle verification passed.
+  Existing chunk-size advisories and deprecated physics initialization warnings
+  remain. No hosted release was published.
+
+## 2026-09-12 - Wall-aware combat pursuit and individual mob recovery
+
+- Hostile mob actions now require both attack range and terrain line of sight.
+  Losing either cancels a pending hostile cast so pursuit can resume; companion
+  hostile casts also cancel when sight is lost. Self buffs and friendly heals
+  cannot make an otherwise obstructed mob hold an attack position. Proximity
+  aggro also checks sight instead of pulling enemies through nearby walls.
+- Static enemies, roaming packs, and summoned enemies share separately tested
+  imperative pursuit rules over the already-loaded dungeon navigation surface.
+  Blocked direct approaches use approved routes through doorways. Routes may
+  finish at a reachable attack position only when that position is both in
+  range and visible; off-surface connectors still require body clearance.
+- Two seconds without meaningful waypoint progress requests a replan. After
+  five seconds, a stuck mob within ten meters of its target may recover to a
+  validated nearby landing on the same floor and within its home leash. Ground,
+  body clearance, route connectivity, attack range, and sight must all pass.
+  This teleport preserves health and threat and has a ten-second cooldown.
+- Distant, wrong-floor, out-of-leash, or unsafe near-target recovery requests
+  instead reset only that mob's combat state and restore its health. A validated
+  home landing is preferred; otherwise it evades and navigates home without a
+  blind teleport. Ten seconds of evade prevents immediate proximity, damage,
+  or taunt re-engagement. Dead enemies are never resurrected. Casting, control,
+  pauses, inactive simulation, and non-authoritative online clients do not
+  accumulate navigation failures or trigger automatic recovery.
+- Regression coverage includes range-plus-sight attack/cast gating, immediate
+  cast cancellation, doorway detours, recovery timing and safety, reset/member
+  isolation, cooldown bypass protection, and near-teleport health/threat
+  preservation. Shipping Stockades meshes independently verify real wall
+  occlusion in both directions and clear sight across all three stair ramps.
+  Pursuing mobs traverse each actual ramp uphill and downhill without false
+  teleport/reset recovery. Existing party and player ramp checks still pass.
+- Browser smoke pass at 1280 x 720 used offline level-16 Priest Rolecheck and
+  Blood DK, Combat Rogue, Unholy DK, and Frost Mage companions. Power Word:
+  Shield applied to Morvane; Attack moved companions down from the entrance
+  and out of its view without ROUTE BLOCKED, and Defias melee/cast events and
+  tank damage followed. Stop plus Recall returned all four living companions
+  to the nearby player while retaining Stop. Inline screenshots show character
+  bodies, equipment, unchanged visible steps, and the existing warm lighting.
+  The browser console had no errors and the existing physics initialization
+  deprecation warning only.
+- Live QA was a short entrance/combat/recall smoke test, not a healed full clear
+  or a manually reproduced side-room wall trap. Wall-blocked pursuit and mob
+  recovery triggers are backed by automated tests; extended side-room combat,
+  physical Android, and live multiplayer QA remain open. Existing lighting,
+  ramp assets, and non-blocking actor collision policy were not changed.
+- Validation: all 229 Vitest files passed, 1,444 tests passed, and six existing
+  tests remained skipped. Final production TypeScript/Vite compilation, texture
+  and performance audits, static compression, and bundle verification passed.
+  Existing chunk-size advisories remain. No hosted release was published.
