- src/lib/map/vision.ts (pure, tested): blockingSegments (walls + closed doors),
segment intersection, computeVisibleCells (raycast viewer→cell-centre, sight radius).
- BattleMap += dynamicVision + sightRadiusFeet (Dexie v12, backfilled).
- MapEditor: new "Walls" tool (draw wall polylines; click a door to open/close),
a "Vision" toggle (auto-enables fog and reveals from the party), sight-radius field,
and "Reveal from party". Moving a PC token accumulates revealed cells via LoS when
Vision is on. Doors/walls render for the GM (amber=closed, green=open).
- Networked players need no new protocol: revealed cells already travel in the snapshot.

- character.portrait + mapToken.image (data URLs, Dexie v10, additive).
- src/lib/img/resize.ts: center-crop + downscale helper (160px tokens / 256px
portraits) keeping IndexedDB + wire payloads small.
- Portrait uploader on the character sheet; token icon uploader in the map token
modal (falls back to the linked character's portrait). Palette PC entries show
the portrait thumbnail.
- Tokens render the image clipped to the circle (HP ring + condition badge on top).
- Realtime: generalized the image channel to many images (map bg + token/portrait
icons), deduped by content and resent on reconnect. Player tokens/party carry an
imageId resolved from the session image cache; party panel shows portraits.
- Also: fix the encounter-picker dropdown text being clipped (drop fixed height).

Render maps at natural resolution inside a CSS-transform world layer (zoom,
pan, fit-to-view) instead of shrinking to maxWidth — large maps are now usable.
Pure viewport math in src/lib/map/viewport.ts (unit-tested). New TokenPalette
places party PCs / active-encounter combatants / blanks in one click with dup
detection; tokens gain optional combatantId (Dexie v9) for live encounter HP.

- Pure geometry library src/lib/map/* (grid, distance 5e/pf2e/euclid, AoE
circle/cone/line/square, polygon rasterize + point-in-polygon, brush, fog set
algebra, player projection) with unit tests.
- Schema: map tokens gain size/kind/characterId/hp/conditions/gmOnly; maps gain
drawings/gridUnit(feet)/gridType/fogVersion + point/drawing sub-schemas. Dexie v8
additive migration; mapsRepo.get + transactional mutate.
- Editor split into a shared MapCanvas renderer + MapEditor tool state machine:
fog via brush/rectangle/polygon (+ size, reveal-all/hide-all), measurement
(system-aware distance in feet), AoE templates (circle/cone/line/square preview),
drawing annotations (freehand/line/arrow/rect/circle/text, GM-only), pings, and
richer tokens (NxN size, character link with live HP ring, condition dots, edit popover).
- Player-facing projection: toPlayerProjection strips GM-only content; PlayerMapView
renders it read-only with opaque fog; uiStore.activeMapId + 'Show to players'; the
player view now shows the live battle map. enemyStatus extracted to
src/lib/combat/playerProjection.ts (reused, and for Phase 18).
9 geometry unit tests; maps e2e covers upload→token→reveal-all→player projection.

- src/lib/assistant/context.ts: buildCampaignContext() assembles a system-aware
snapshot led by an explicit systemConstraint (anti cross-system hallucination),
party, recent encounters with computed difficulty, quest/note summaries.
pickCreatureCandidates() pulls level/CR-appropriate creatures from the correct
bestiary so LLM tips are grounded in real data.
- src/lib/assistant/patterns.ts: difficultyTendency() + detectThemes() classify
whether the DM's encounters skew too easy/hard, rating each fight against its
party-level snapshot.
- Encounter schema gains optional partyLevelsSnapshot + outcome (Dexie v7, additive).
Combat tracker snapshots PC levels at start and rates difficulty against them.
17 assistant unit tests (context + patterns).

- Homebrew entity (monster/spell/item/feat/condition) — Dexie v6, repo, hook,
cascade-deleted with campaign
- Homebrew editor page: per-kind fields + description, create/edit/delete
- Compendium merges campaign homebrew of the matching kind (HB badge, generic
HomebrewDetail) with the same cross-links (add monster->combat, spell/item->character)
- Content packs: export/import homebrew as JSON (validated, ids reassigned)
- System extensibility documented via the existing RulesSystem registry seam
- Fix: card editors (homebrew/npc/quest/note) debounce-save the FULL snapshot, not
partial patches — editing two fields fast no longer drops an edit
New homebrew e2e + cascade test coverage.

- Condition durations + auto-expiry: timed conditions tick down on the affected
combatant's turn and drop at 0 (engine tickConditions; UI rounds field + (Nr) chip)
- Initiative: Roll-all (d20 + per-combatant bonus, re-sort anchored) + group/quantity add
- Combat log: per-round event feed (turns, round changes, damage/heal, expiries,
removals) + in-memory Undo of the last change
- Encounter difficulty budget: 5e XP thresholds + PF2e level budget (pure lib +
tests); live difficulty/XP-award readout from monster combatants vs the party
- Combatants carry initBonus + cr/level; compendium add-to-combat passes them
18 new unit tests (durations, applyInitiatives, budget), new combat-depth e2e.

- Inventory + currency + encumbrance vs carrying capacity
- Class resources with correct short/long/daily rest recovery (applyRest)
- Spellcasting: slots (+pact), known/prepared spells, derived DC + attack
- Defenses: 5e death saves/inspiration/exhaustion, pf2e dying/wounded/hero points
- Derived weapon attacks + passive perception via extended RulesSystem
- Dexie v2 migration backfills new fields; debounced save flushes on pagehide
- 9 new unit tests, new character-depth e2e; all green
