Lock recovery hatches in dispatched turns

 Dispatch receipts should use Bifrost's own public persona in the Bifrost governance channel. `tools/dispatch-agent-requests.mjs` reads `BIFROST_DISCORD_CHANNEL_ID` or `DISCORD_BIFROST_CHANNEL_ID` for the receipt target, uses persona name `Bifrost`, and defaults the persona avatar to the public `src/Bifrost.Web/wwwroot/img/bifrost-profile.png` raw GitHub URL unless `BIFROST_DISCORD_PERSONA_AVATAR_URL` or `DISCORD_PERSONA_AVATAR_URL_BIFROST` overrides it. Receipt text must lead with the concrete repo and work title, not a generic "recent consensus" summary, and must not expose request ids, workspace paths, log paths, or other debugging debris in Discord.
 The dispatcher now tags those Discord receipts with the Bifrost request id as bridge provenance, and dispatched Codex turns inherit default bridge provenance environment variables so any explicit `tools/bifrost-bridge.mjs` crossing inside the turn can land on the same request trail without hand-carried flags. When `BIFROST_BRIDGE_BASE_URL` and `BIFROST_BRIDGE_TOKEN` are configured, the dispatcher also records `/dispatch/runs/*` receipts in the hosted app so Bifrost keeps a first-class run ledger for launch, completion, cancellation, and failure.
 Those dispatched turns also inherit Bifrost-owned GitHub gates through environment config. `git` and `gh` wrappers are prepended in `PATH`, a `pre-push` hook backs up raw Git pushes, raw `git push` stays blocked inside dispatched work even with `--no-verify`, and mutating `gh` commands are blocked too unless the bridge explicitly authorizes the GitHub mutation it owns.
+Those dispatched turns also lock the local-only recovery hatches. `--allow-ungated-github`, `BIFROST_ALLOW_UNGATED_GITHUB`, `--allow-unreceipted-activity`, and `BIFROST_ALLOW_UNRECEIPTED_ACTIVITY` are refused inside dispatched work so an agent cannot quietly downgrade itself out of Bifrost's gate or receipt trail.
 When that same bridge configuration is present, `tools/agent-transport.mjs` records `/transport/receipts` entries for queue, claim, release, and close operations on the request lane. The packet still lives in CultCache. The hosted receipt row is the Bifrost-side witness that an agent or dispatcher touched it.
 `apply-snapshot` is treated as a mutating import path too. It now fails closed without that same bridge configuration and derives request-lane receipts from the imported state delta, so a snapshot can no longer rewrite queue or claim state behind Bifrost's back.
 Those mutating scripts now fail closed without that bridge configuration. Use `--allow-unreceipted-activity true` or `BIFROST_ALLOW_UNRECEIPTED_ACTIVITY=true` only for explicit local recovery work where you are intentionally accepting a blind spot.
