Structured world/player/NPC stats, two-way flags, and sticky milestones
per scenario (stat_schema). The AI proposes a per-turn delta; a Python
engine referees it (clamp to min/max, per-turn cap, cooldown, counters).
Band word-labels plus a fixed stat guide (descriptions + full ranges)
keep the model grounded. World State drawer + Insights delta report;
undo/retry roll it back via the Phase 11 snapshot pattern.
- migrations 26-28 (scenarios.stat_schema, adventures.world_state,
actions.world_state_before); all nullable, additive, safe on existing rows
- migration 29 raises the default context budget 4096 -> 16384
(custom values preserved)
- seeded demo scenario 04-rpg-world-state.json (Bandit Camp)
- 19 new tests (33 total pass)

The reasoning model truncated replies before the end-of-reply [HP-N]
tag, so damage was never reported and HP stuck at 100. Move the tag to
the FIRST line of the reply so it survives truncation, and clarify the
wording (concrete example numbers instead of the literal "[HP-N]" that
confused the model).
Also make the seeder the source of truth for demo content: it now
reconciles an existing seeded scenario in place when a seed file
changes (keeping the scenario row and its adventure FKs), instead of
only inserting when missing — otherwise fixes to already-seeded demos
never reach production. No-op when content already matches, so it stays
cheap on every boot.
Verified end-to-end through the quickjs engine, including a truncated
reply still applying damage, and the in-place update path.

Adds "[Demo] The Goblin Ambush (HP script)": a combat scene whose script
tells the AI the current HP and to tag damage/healing as [HP-N]/[HP+N];
the AI decides the amounts, the onOutput hook applies them to state.hp
(clamped 0..100), hides the tags, and flags death at 0. Showcases the
new left State drawer with live variables. Verified through the real
quickjs engine: a simulated attack drops HP, a potion heals (clamped),
a fatal blow sets state.dead.

Idempotent seeder inserts public, unowned demo scenarios from
backend/app/seed_data/*.json if a public scenario with the same title
is missing, so a fresh Neon database (and any clone) gets demo content
guests can play immediately. Ships two scenarios: the Sunken Crypt of
Vharos (all four script hooks) and Signal from the Derelict (sci-fi,
context-engine focused).
