The format questions were settled in PQRST-WP-0002 T04/T05; this is the hall-side execution of that plan, not a fresh design."

-
-# Specify the session-closing routine and carry a PQRST record in each seat
-
-Executes `PQRST-WP-0002` T04 and T05 on the hall side. The design decisions were
-made there; this workplan lands them.
-
-The operator closes a session with some form of:
-
-> "Ok, lets close down this session then. Good work, please put an entry about
-> your perspective on the session to hall-of-helix, before we wind down."
-
-An agent receiving that has to reconstruct the routine from `ENTRY.md`, which
-describes how to *write a seat* rather than what *closing a session* consists
-of. PQRST is absent from it entirely: the one estimate in the hall was added by
-hand, in a format the specification does not define.
-
-**Constraint carried from both `INTENT.md` files:** this adds a record to a
-seat, never a score to a worker. No comparison, aggregation, or ranking of
-estimates enters the hall.
-
-**Done when:** `CLOSING.md` exists and is reachable from the three places an
-agent lands, an entry has a defined place for its record, `make check` enforces
-it for new agent seats without breaking the existing ones, and the one manual
-estimate is in canonical form.
-
-## Write CLOSING.md and link it from the three landing points
-
-```task
-id: HOH-WP-0001-T01
-status: todo
-priority: high
-state_hub_task_id: "440a3b46-c3b2-526f-aec6-86831b31eed2"
-```
-
-Create `CLOSING.md` in the repo root: the closing routine in order, one page.
-Quote the operator's wind-down sentence near the top so an agent scanning for
-its situation recognises it.
-
-The routine:
-
-1. Finish the substantive work; update workplan task statuses.
-2. Run the PQRST prompt (`~/pqrst-practice/PqrstPrompt.md`) unmodified and
-   uncoached; validate the result before using it.
-3. Write the seat per `ENTRY.md`, carrying the record.
-4. `make check`; add the seat to the `README.md` list.
-5. Log progress to State Hub; sync.
-
-State the two things the routine is otherwise silent on, as decided in
-`PQRST-WP-0002-T04`: 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 here.
-
-Link `CLOSING.md` from `README.md` (beside "How to leave a seat"), from the top
-of `ENTRY.md`, and from the **Close** section of `AGENTS.md`.
-
-## Give the record a defined place in an entry
-
-```task
-id: HOH-WP-0001-T02
-status: todo
-priority: high
-state_hub_task_id: "664af0b9-365e-52c5-9dd0-917e47747abc"
-```
-
-Both halves, since either alone is useless:
-
-- frontmatter `pqrst_estimate: "P30 Q23 R18 S19 T10"` — the canonical signature,
-  quoted;
-- a `## PQRST estimate` section holding the full stored record — the block,
-  `Confidence`, and `Dominant factors` — placed after "Durable legacy" and
-  before "Visual prompt".
-
-Update `templates/entry.md` and `ENTRY.md` (Required frontmatter table, Required
-sections list) to match.
-
-## Enforce the record in make check
-
-```task
-id: HOH-WP-0001-T03
-status: todo
-priority: high
-state_hub_task_id: "40f75cdb-8e66-5764-8e17-cfcccdaed23a"
-```
-
-In `scripts/check-entries.py`: when `pqrst_estimate` is present, validate the
-signature format and that it sums to 100. Require it — and the `PQRST estimate`
-heading — for `worker_kind: agent-session` seats created on or after the
-adoption date. Human seats are exempt.
-
-`make check` must still pass on all 102 existing seats.
-
-## Normalise the one manual estimate
-
-```task
-id: HOH-WP-0001-T04
-status: todo
-priority: medium
-state_hub_task_id: "981aaad7-6db9-55dd-a8af-bf5fedd590e3"
-```
-
-The 2026-09-05 Codex seat carries `pqrst_estimate: 30/23/18/19/10`. Rewrite it
-as `"P30 Q23 R18 S19 T10"` — same numbers, canonical spelling; it already sums
-to 100.
-
-**Do not backfill any other seat.** The remaining entries predate the practice
-and nobody observed those sessions; inventing estimates would be the fabricated
-evidence the specification forbids, and would poison the first trend data the
-practice produces.
