Bifrost b2e0bb2 (#57) adds a fourth element tail_gaps to chat_pending.v3: the rooms whose tail lines are incomplete (read failed or timed out, or lines trimmed). Huginn main decoded a three-field reply and would fail with LengthMismatch against it.

Changed (crates/mind-body):

  • ChatPending.tail_gaps: Vec<String>, #[serde(default, skip_serializing_if = "Vec::is_empty")]: three-field replies still decode (none named); an empty fourth element is the same answer.
  • render_tail takes the gaps: a named room (among the process's rooms) renders as "Unknown, not quiet: ..." whether or not it has lines; only an unnamed room with no line is "No tail line for: ... they were quiet". The old note's "or the mouth could not read them" is gone since the mouth now says which. Gaps flow poll -> Session -> PersonaInbox -> first line, like the tail.
  • Fixture copied unchanged from Bifrost b2e0bb2 (persona-chat-v7).

Verified (Linux Yggdrasil, unshare -r cargo test -p mind-body): --lib 882 passed (0 failed, 1 ignored, pre-existing), after rebase onto main 96a88d3 (render_tail is now render_tail(config, addressing, tail, gaps, rooms, seen, waiting_ids)); --test chat_rudp 16 passed. New: chat_rudp 1 (three-field, four-field with gaps = Bifrost's own bytes, four-field empty, unnamed quiet room, all over real RUDP), chat_client 1 (golden round trip, default), persona 1 (unknown vs quiet through the full first line, and from the golden bytes).
Mutations (hand-applied, restored): dropping default on tail_gaps fails 5 lib tests and 6 RUDP tests; breaking the unknown rendering fails the persona test. tools/cargo-mutants.sh was not run.
No cut_spec covers this change (huginn cut eureka-substrate wake-reads-room-tail matched 0), so no cut_report is admitted.
With no line offered and a room named, the section reads only the unknown note, never "empty" (pinned by a_named_gap_with_no_lines_reads_unknown_and_never_empty).

Known limit: a pre-#57 mouth is indistinguishable from a 4-field mouth with an empty reply, so the "they were quiet" wording holds only for a mouth that sends tail_gaps (Bifrost says v3 is undeployed).

Bifrost b2e0bb2 (#57) adds a fourth element `tail_gaps` to `chat_pending.v3`: the rooms whose tail lines are incomplete (read failed or timed out, or lines trimmed).

Bifrost b2e0bb2 sends [persona, deliveries, tail, tail_gaps]; a three-field decode failed LengthMismatch. The field defaults empty, so three-field answers still decode, and render_tail splits unknown (named) from quiet (unnamed, no line).
