# 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 2).
  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`.
