Workstream F of the character-depth/ghost-log spec.
- InventoryPanel.tsx: essence balance, owned unlocks/items (terminal
listing + Codex-style rarity-glow borders on items), and a buy flow
for a small fixed unlock catalog (currently just "listening_tool",
the only key the contract names) with afford/can't-afford button
states. Prices are fetched from a best-guess /api/inventory/catalog
endpoint and fall back to a flagged "(est.)" price sourced from the
spec's own worked example when that endpoint isn't available yet —
the contract doesn't define a price-list REST shape.
- SigilDesigner.tsx + lib/sigil.ts: constrained geometric builder —
points snap to 24 fixed clock-face slots around a circle, capped at
12 to match the backend's payload limit, connected in placement
order. Five hand-drawn stroke-only rune glyphs (eye/crescent/key/
spiral/thorn) overlay the center. Point-cap enforcement, rune
selection and payload-shape building are pure functions in
lib/sigil.ts, unit-tested directly. Saves via POST
/api/inventory/sigils (path inferred; payload shape matches the
contract exactly: {"points": [[x,y],...], "rune": str}). Art
direction: the builder itself reads like a plotting/debug tool
(crosshair cursor, monospace coordinate HUD) while the rendered
lines + rune glow violet, consistent with GhostGlyph's conventions.
- lib/evp.ts: new evpThresholdDb(hasListeningTool) pure function and
EvpListener.start() now accepts { hasListeningTool } to lower the
EVP anomaly threshold (8dB -> 4dB) when the unlock is owned — wired
from useAuth().user.unlocks in SeancePage's EvpPanel, a real
gameplay effect on which faint signals register as anomalies.
- api.ts User type gains unlocks/essence per the contract's /auth/me
extension; new InventoryPage.tsx mounts both components behind auth
at /inventory, linked from the séance nav.
166/166 tests pass (137 pre-existing + 29 new), i18n coverage check
clean, tsc -b clean.
