CLOSING.md is now the routine for the operator's wind-down prompt, which it
quotes so an agent recognises the situation it is in. Linked from README.md
beside "How to leave a seat", from the top of ENTRY.md, and from AGENTS.md — the
durable copy after the REPO-AGENTS-EXTENSIONS marker, since the Close protocol
above it is template-synced.
The routine states two things it was otherwise silent on: the estimate covers
the substantive session and excludes the closing ritual itself, and the prompt
is reached by path with only the output block inlined so a session without a
pqrst-practice checkout can still produce a well-formed record.
Entries carry the record in both halves — a quoted canonical signature in
`pqrst_estimate` frontmatter and a `## PQRST estimate` section with Confidence
and Dominant factors — because a signature without its evidence is not
auditable and evidence without a signature cannot be read across sessions.
ENTRY.md and templates/entry.md updated to match.
check-entries.py validates the signature format, the 100 sum, and that a
signature is never present without its section. Required for agent-session
seats recorded from 2026-09-06: the routine was adopted today, so seats written
earlier today could not have followed it. Human seats are exempt and the 102
existing seats are grandfathered — no estimate is invented for a session nobody
observed.
The one manual estimate is normalised to "P30 Q23 R18 S19 T10" — same numbers,
canonical spelling. Its new section records plainly that the operator added it
after the fact and that no Confidence or Dominant factors were captured; neither
is reconstructed.
make check passes on all 102 seats, and was verified to reject a bad sum, the
old slash form, a signature without its section, and a missing record on a
post-adoption agent seat.

Companion to PQRST-WP-0002 (T04/T05), which settled the design. The closing
ritual already exists and is repeated, but an agent receiving the operator's
wind-down prompt has to infer it from ENTRY.md, and PQRST is absent from it.
Four tasks: write CLOSING.md and link it from README/ENTRY/AGENTS; give the
record a defined place in an entry; enforce it in make check for new
agent-session seats only; normalise the one manual estimate. No backfill of
seats for sessions nobody observed.
