# 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: done
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: done
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: done
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: done
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.
