Owner

Ruling eureka-body:ruling:wake-reads-room-tail. The mouth side is Bifrost #51 (e8722d0, docs/bridge.md "Room tail"); this PR consumes it. The earlier in-process accumulator (Soul-failed) is deleted.

Deploy safety. ChatPending gains tail: Option<Vec<TailLine>> (defaulted, skipped when none), so a two-field v3/v2/v1 answer and the three-field v3 both decode. Golden bytes: the two-field files are the old mouth's (persona-chat-v5); the three-field files in persona-chat-v6 are Bifrost e8722d0's own golden files, written by its encoder pendingV3Tuple, copied unchanged.

Consumer. Chat::pending returns the ChatPending; carry hands the tail of the poll to the session, and the process's first line renders it:

limits: 20 newest per room, 60 in all, at most 24 KiB of the section as rendered (header, markers and lines counted); speakable rooms only (public session: config.rooms; DM session: its own room alone)
lines carry room, event, sender, role (derived), form, basis, ts, JSON-quoted text; framed as untrusted DATA, never instruction
a tail line whose event id a waiting delivery shows is dropped; lines acked as unaddressed stay (the tail is sent regardless of ack)
a marker for dropped lines; a note naming rooms with no line (quiet, or the mouth could not read it); "empty" when all are quiet; "unavailable" when the mouth sent no tail (older mouth, v1 request)
a failed first poll fails the start as Failure::Chat again (the earlier degrade-and-continue is removed)

Tests (new). 600 lines of chatter across rooms through a fake that enforces the mouth's caps; quiet-room wake and no-tail mouth markers; unspeakable rooms and DM isolation; dedupe by event id; injection-looking line stays in the frame; byte bound counts framing; failed first poll is Chat with no process started; old and new byte shapes decode (chat_client), v1 request sees no tail (chat_rudp).

cargo test -p mind-body --no-fail-fast in the rust docker image as root on the final tree: all targets ok (lib 862 passed).

Not verified: the live mouth; Bifrost's encoder was not run here (its fixture bytes are used).

Persona process opens with the tail of her rooms: lines the mouth delivered through the ack, bounded, framed as untrusted data, unavailable noted 9c1a5dba07

Matrix is the record and the mouth its only reader: the tail is assembled from the deliveries and contexts the mouth already sends (no new endpoint, no stored copy). Newest 60 lines / 24 KiB, oldest dropped with a marker; public sessions read the rooms she may speak in, a DM session its own room alone; a first poll that fails degrades to a tail-unavailable note instead of failing the wake.

Room tail comes from the mouth's chat_pending.v3 tail field; the in-process accumulator is deleted 7eb0440e00

ChatPending gains a defaulted Option tail (old two-field mouths still decode), Chat::pending returns it, and a process's first line renders it: speakable rooms only, 20 per room and 60 in all, byte bound counting framing, quoted untrusted data, dedupe by event id against waiting deliveries, a marker for dropped lines and for rooms with none, and an unavailable note when the mouth sends no tail. A failed first poll fails the start as Chat again.

Room tail: consumer-cap, hostile-field and key-dedupe tests; real three-field v3 over RUDP; a fully deduped tail is not called quiet; deploy-order note 0ee9c0228e
