Pin IR-WP-0005-T02 review to memo version 3.
The consumed T03 approval IDs cannot be created again. The T03 review
package and the sitting list pins now name three new approval IDs.
Binding digests and the sitting act records stay as they are.

# Compact sitting review mandate
This is a new exact-record package for seven 2026-09-14 sitting memos.
v2 (2026-09-21) adds exactly one record, `memo:infd-20260921-b01` (the
SECRETS-WP-0009-T03 spend envelope), with native pins from informed-decision
`docs/evidence/2026-09-21-budget-approval-create.json`. The seven v1 records
and the identity bar are unchanged.
It is not an expansion of `examples/informed-decision-t03` / FLEX-WP-0027.
`memo:infd-20260914-c01` is omitted (create-client still undecided).
v3 (2026-09-21, `FLEX-WP-0032`, `FLEX-DEC-2026-017`) adds one action, `list`,
for informed-decision's decision overview (`INFD-IN-0008`). It is a separate
rule, not an extra member of the act set, and it changes nothing else:
- `read` and the five acts keep the v2 rule unchanged — the same eight records,
the same 900-second MFA window. A `list` allow satisfies no other action.
- `list` covers the **union** of this package's eight records and the three
`SECRETS-WP-0010-T03-*` records from `informed-decision.t03-review`, each
pinned by approval id, binding digest and its own memo version (T03 at 3).
Scope stays exact-record: a memo is listable only once someone admitted it.
The operator declined resource-type-wide scope because the PDP checks no
recipient, and a type-wide rule would have left consumer code — which the
consumer itself says is not an entitlement — as the only scope.
- `list` carries the same identity bar with a **12-hour** MFA window instead of
900 seconds. Looking back at your own outcomes is not binding a new one. The
bar is lighter, not absent: the PDP still states a bound.
- The KeyCape stale-timestamp defect (`INFD-IN-0005`) is **not** worked around
here. `read` stays strict; that defect is key-cape's to fix.
The identity bar matches T03: authenticated informed-decision caller,
`net-kingdom-admins`, fresh KeyCape AAL2 MFA. No permission follows from
memo content or presentation state. TokenReview must admit
`system:serviceaccount:informed-decision:review` before this package is
served. Membership tenant provenance may follow the accepted registration
route; it does not assert directory membership in tenant:platform.
Only a real human uses accept. This package neither issues nor consumes
approval. Native pins: `docs/evidence/2026-09-15-sitting-approval-creates.json`.
