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

Browse source 
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.

Rulings: `tell-is-just-the-message`, `tell-delta-three-defaults`, `what-reaches-each-turn-ruled`. Owner: `persona.rs`. A session is one process and nothing compacts it, so what she was told stays in her context; a line carries only what is new.
- **First line of a process** (`PersonaInbox::start_line` -> `whole_line` -> `render_input`): `TURN_INSTRUCTION` (the Perfect Machine, stewardship, inversion of control, originator vision as evidence, her tools, work that changes a repo goes to a Self run), a refused batch's note if an earlier process left one, her latest runs, responsibilities, recall, plan windows and tempo, the rooms and people she may name, the room tail (`render_tail`: the newest 60 lines / 24 KiB of what the mouth has delivered of her rooms through the ack, a direct message's own room alone in its session, framed as untrusted data with a truncation marker, or an "unavailable" note when the start's first poll failed; ruling `wake-reads-room-tail`), `MESSAGES_HEADER`, the messages, and the tail: an opener when there are no messages (`WAKE_ASK` on a day she has started no Self run of her own, else "No new messages."), then, when there are messages, `ANSWER_MESSAGES`, then `WORK_QUESTION` on every first line, with messages or without. Later lines end on `WORK_TAIL` (`tell_line`: plain, refused and stale retells alike). A wake is always a first line: a session starts with an empty batch and gets the whole machine, so a wake never arrives as a bare later line. A restart (cache TTL, cap rotation, ceiling flush, failed result) is a new process and tells the whole machine again.
- **First line of a process** (`PersonaInbox::start_line` -> `whole_line` -> `render_input`): `TURN_INSTRUCTION` (the Perfect Machine, stewardship, inversion of control, originator vision as evidence, her tools, work that changes a repo goes to a Self run), a refused batch's note if an earlier process left one, her latest runs, responsibilities, recall, plan windows and tempo, the rooms and people she may name, the room tail (`render_tail`: the mouth's `tail` on `chat_pending.v3`, field 2, a defaulted `Option` so an older two-field mouth still decodes and is told the tail is unavailable; per speakable room the newest 20 and 60 in all, at most 24 KiB as rendered, framed as untrusted data with a truncation marker and a note naming rooms with no line; a delivery's event id drops its tail line; a DM session reads its own room alone; nothing is accumulated in the organ; ruling `wake-reads-room-tail`), `MESSAGES_HEADER`, the messages, and the tail: an opener when there are no messages (`WAKE_ASK` on a day she has started no Self run of her own, else "No new messages."), then, when there are messages, `ANSWER_MESSAGES`, then `WORK_QUESTION` on every first line, with messages or without.

A restart (cache TTL, cap rotation, ceiling flush, failed result) is a new process and tells the whole machine again.
- **Later line** (`tell_line`): the organ's notice lines first, a refused batch's note before the messages, then `earlier`/`message` lines, then `WORK_TAIL`. No instruction, no machine; `tell_line` reads nothing from her mind.
- **Notice lines**: `notice role=organ at=... text="Your Self run <label> ended: <outcome>"`. They are not messages and answer to no delivery. Source: one read of her Self run slot (`holders` for SelfRun) at most once per `SLOT_READ_EVERY_S`=15 s (the chat poll is 5 s; the slot read cost 1.4-2 s of daemon CPU on Eureka's 14.7k-document mind, so 5 s was 28-41% of a core); `slot_seen` holds the runs last seen holding it, whoever started them, and her own start joins it unread. A run seen to leave gets its closing read once. A failed read keeps `slot_seen` and delays the notice. Only a live session fills `ended`, so a notice never starts a session; with notices and no deliveries `poll` reports pending and `tell` writes a line of notices alone. A run she did not start that opens and ends between two reads is unseen (about 10 of 157 Self runs at 15 s); the next first line shows it.
- **Flush** (`flush_text`): `TURN_REMINDER` (the stewardship sentence) plus the ask, never the first-line instruction. It records what it shows (`flush-shown`).
