App-shell HUD (mounted in App.tsx alongside HauntingLayer, visible on
every screen) that shows ambient idle status until a séance is active,
then streams `tell` WS frames as terminal-style log lines with a
"hacker witch" crescent-arc evil-meter gauge (occult sigils/runes fused
with Transcript.tsx's monospace log vocabulary).
- lib/evilMeter.ts: pure function computing a malevolent<->benevolent
belief from the accumulated tell history — starts wide/uncertain,
narrows geometrically and shifts per tell (deterministic hash of the
tell text, since tells never leak ground truth), and snaps to
definitive certainty on a successful ritual_complete's
revealed.alignment. Fully unit tested (narrowing, ordering,
determinism, ritual override, idle/empty history).
- lib/ghostLogBus.ts: tiny typed event bus (mirrors lib/haunting.ts's
HauntBus) so the app-shell-level GhostLog can react to live séance
frames — SeanceProvider is only mounted inside the séance route, so a
shell-level sibling can't read its context directly.
- state/seance.tsx: publish entity/tell/ritual_complete onto the bus,
and session_end on provider teardown so the HUD falls back to idle
when the seeker leaves the séance page.
- lib/types.ts: add the `tell` and `ritual_complete` server frames from
the Character Depth spec's Contract section (only what this
workstream consumes).
- components/GhostLog.tsx/.css: the HUD itself, plus i18n keys in
en.json/es.json.
168/168 frontend tests pass (137 pre-existing + 20 evilMeter + 11
GhostLog); tsc -b and the i18n coverage pretest are clean.

Renaming: "Armory" read too militaristic for a séance app. Landed on "The
Reliquary" (not "The Threshold" — that name was already taken by the
landing-page back-link).
Spec addendum: added a visible essence currency (earned per summon, spent
on unlocks — distinct from the hidden favor score) and a fourth judgment
verdict, cross_over, for compassionately helping a genuinely benevolent
"stuck" spirit move on rather than just trusting or banishing it. Updates
workstreams B/C/E/F accordingly before any of them are dispatched.
First sub-project of the "make contact feel real" arc (spec:
docs/superpowers/specs/2026-07-23-possession-presentation-design.md).
Direct Contact replies now feel like a spirit fighting through static to
hold the channel rather than a plain chat bubble:
- backend/app/possession.py: compute_stability(rarity, magnitude, rng) —
a 0.05-0.98 score per reply (rarer entity + stronger triggering anomaly =
cleaner signal), rng injectable for a later quantum-RNG source.
- ws.py sends stability on reply_start; audio synthesis for that reply gets
noise/bitcrush scaled by instability (1 - stability) via a new
instability param on synthesize_spirit_voice — effects.py itself is
untouched, only the params fed into it.
- frontend/src/lib/possession.ts: renderPossessedText — pure, deterministic
(tick-seeded, no Math.random) text corruption with self-correcting
glitch bursts, wired into Transcript.tsx's streaming reply display.
Stored transcript/reply text is unaffected — this is presentation only.
78/78 backend, 137/137 frontend tests passing.
The gap-g-readme merge commit (57a8914) staged this fix but never
re-staged it after editing, so the merge landed with the pre-fix content —
the working tree had the correction but git didn't. No functional change,
just closing the gap between what was intended and what was committed.
