 Joined officers gate whether `requires_joined` player deployments are loaded at all. Rewards and post-battle choices can add or remove joined officers without deleting their saved roster snapshot, so a later rejoin can preserve progression. When a save loads, `CampaignState` scans completed scenarios in campaign order and reapplies only officer join/leave transitions from rewards and the saved `applied_post_battle_choices` ledger, allowing added recruitment rewards to reach older saves without replaying gold or items. Old saves without the ledger can backfill a choice id only when exactly one completed scenario choice matches saved flags. Roster entries are keyed by `officer_id` when available, so future scenarios can deploy the same joined officer under different scenario-specific `unit_id` values. Saved progression overlays final battle stats for now; a later equipment refactor should split base stats from equipment bonuses before adding item leveling or stat recalculation. New battles currently start player units healed to their saved maximum HP/MP. Skill access is carried in roster snapshots, with class defaults still applied for old saves that do not include skills. Promoted class ids are saved in the roster, and the next battle rehydrates class-derived movement, growth, skills, and range from the saved class id before equipment range is recalculated.
 
-Inventory and campaign flags are copied from `CampaignState` into `BattleState` when a scenario starts. The pre-battle Chapters overview reads `CampaignState` chapter progress and can load completed or current battles without mutating the save. Briefings preview first-clear rewards and show completed replay rewards as already claimed. The pre-battle Save menu can write the current campaign state to `user://campaign_manual_save.json`, and loading that checkpoint restores it into `user://campaign_save.json` before re-entering the same pending-choice, completion, or current-briefing branch as startup. Pre-battle shop stock comes from the loaded scenario's `shop.items` list plus matching `shop.conditional_items` blocks, with optional finite limits from item entries or `stock` maps. Shop purchases and 50% sell-back are campaign transactions: they update saved gold, unequipped inventory, and finite-stock purchase counts immediately, write the save file, and refresh the already-loaded battle inventory before the player begins the battle. Pre-battle Armory equipment changes use the same equipment rules as battle HUD equipment changes, then immediately save merged roster equipment/stat snapshots and inventory stock. Pre-battle Roster uses scenario `roster.max_units`, `roster.required_officers`, and `roster.required_units` to mark optional player deployments as sortie or reserve; reserve units remain in the candidate list but are excluded from board occupancy, drawing, selection, AI targeting, and living-unit victory checks. Non-controllable player units can act as protected escort targets: enemies can attack them and conditions can reference them, but they are skipped by player selection, Armory, Formation, counterattacks, and campaign roster progression snapshots when `persist_progression` is false. Scenario `ai_target_priority` nudges enemy movement and damage-skill scoring toward important targets such as envoys without overriding defeat bonuses or range checks, and `set_ai_target_priority` events can retune that battle-only pressure after an ambush, gate closure, or escort exposure. Pre-battle Formation uses the loaded scenario's `formation.cells` and only mutates current battle unit positions before battle-begin events fire. Destination victory cells from `unit_reaches_tile` conditions are exposed to the scene for objective overlays and tile info, and can be expressed as one `pos` or a multi-cell `cells` list. Movement-triggered `unit_reaches_tile` events receive the unit that just moved, so ambushes and pickup events fire on entry rather than from units already standing on a marker; `unit_defeated` events receive the fallen unit before final victory/defeat checks, allowing named-officer reactions and last-moment reinforcements. Briefing data can append matching `briefing.conditional_lines`, and scenario events can use `when.campaign_flags` to branch dialogue, objective changes, item and gold pickups, AI target-priority shifts, and reinforcements from saved campaign choices or `when.after_event` to wait for earlier scenario beats. Consumable use can restore HP or MP or cure matching poison/seal/snare/disarm statuses, and in-battle item use, event pickup grants, event gold pickups, plus equipment swaps mutate only the battle copy until victory; defeats and restarts do not spend saved items, keep picked-up items or gold, or preserve in-battle gear changes. Post-battle choices write campaign `flags` only after the result-panel button is pressed; if the player reloads after rewards are saved but before selecting, the pending scenario id restores the victory choice panel without replaying rewards. The next battle button stays locked until the campaign choice save succeeds. Equipment rewards share the same `item_id -> count` inventory stock, cover weapon, armor, and accessory slots, can be equipped from the side HUD before the selected unit moves or acts, and do not appear in the consumable action menu. Named equipment currently uses the same stock model with a presentation-only rarity tag rather than unique item instances. Already completed scenarios can be replayed without granting duplicate rewards, choices, replay inventory consumption, event gold pickups, save writes, current-scenario advancement, or finite-stock purchases; pre-battle Shop, Armory, Roster, Formation, and Save are disabled on completed-scenario replays to avoid side effects.

 The battle scene owns presentation feedback: briefing and result states use menu BGM, briefing headers combine `CampaignState` chapter ranges, campaign order, and title data with `BattleState` briefing, objective text, condition-progress text, and defeat-risk text, active battles use battle BGM and show an objective/progress/risk panel fed by `BattleState`, objective-update signals show a short HUD notice and refresh the objective panel immediately, dialogue lines can show optional cached portrait textures or speaker-initial fallback panels in an expanded visual-novel-style panel, can place the portrait on the left or right side of that panel, and expose progress plus previous-line controls while a sequence is open, the side HUD reuses cached officer portrait textures for the selected unit or hovered unit, board units render low-HP warning rings, HP bar color states, and active support/debuff/poison/seal/snare/disarm status pips from battle state fields, hover previews are rendered as target badges from existing `BattleState` forecast APIs, hover unit info shows class, movement type, AGI, movement, range, and equipped gear, equipment option menus show stat/range/effect deltas, result and inventory summaries show named equipment with compact rarity tags, selected area tactics highlight their affected cells, the Threat toggle overlays enemy physical and hostile tactic reach while tile info names threat sources, estimates physical damage, and summarizes hostile tactic damage or status effects against occupied cells, log/result hooks trigger placeholder SFX, support, debuff, poison, seal, snare, disarm, objective updates, AI target-focus changes, and item/gold pickup effects use distinct feedback, `BattleState.unit_motion_requested` asks the scene to interpolate a unit's draw position during movement, and `BattleState.combat_feedback_requested` asks the scene to draw transient floating combat text without changing battle rules.

 `post_battle_dialogue` plays once after victory and before the victory result panel opens. Lines may be plain strings or objects with `speaker`, non-empty `text`, optional `portrait` resource paths such as `res://art/portraits/cao_cao.png`, and optional `side` values of `left` or `right` for portrait placement. Portrait paths must stay inside the project, point to existing readable image files, and keep at least a 512x512 source resolution. If `side` is omitted, it defaults to `left`. If `portrait` is omitted, `BattleState` uses a matching officer definition's default portrait path when the line's `speaker` matches the officer `name`. If no usable portrait is loaded, the battle scene falls back to a speaker-initial panel.
