P2-1: a money-tier request id is reserved the moment its prompt is raised
(money_pending_ids); a replayed envelope (drain overlapping the live
subscription, or deliberate) returns AlreadyPending / the cached result and
can never raise a second prompt or re-sign. Applies to sign and escalated
encrypt. Regression test covers both replay-while-pending and replay-after-
completion.
P2-3: the money modal for a pay-committing encrypt now shows the inspected
plaintext (escaped + truncated exactly like the sign path), so the user sees
what they are agreeing to pay, not a blind label.
Hardening:
- payment marker set widened (amount, total, price, msat), TODO(audit) kept.
- identity dropped mid-session now answers identity_mismatch on the channel
(refusal_json per op type) instead of silently timing out the site.
- session-end payload carries reason: revoked (wallet end) / expired (TTL or
idle sweep, newly published by the tick) / logout (site's own).
- decrypt gets its own soft-cap window (30/min) and an honest 'reading your
messages' notice, distinct from the signing-volume toast (new locale key
in all six languages).
- money answers route by the session's site channel key, never the display
domain.
- committed the auditor's env-gated NIP-44 v2 interop test against
nostr-tools (GOBLIN_CT1 harness).
