list is a separate rule with exact-record scope over the union of the eight
sitting records and the three T03 records, each pinned by approval id, digest and
its own memo version, with a 12-hour MFA window. read and the five acts keep the
v2 rule unchanged — same eight records, same 900-second window — so a list allow
satisfies nothing else.
The operator chose exact-record scope over the consumer's preferred type-wide
scope: the PDP checks no recipient, so type-wide scope with a relaxed window would
have left the consumer's structural match — which the consumer itself says is
not an entitlement — as the only scope. The 12-hour bound replaces the requested
"no bound" so the PDP still states one. The KeyCape stale-timestamp defect is not
worked around; read stays strict.
417 evaluator checks: 168 v2 unchanged, 231 list, 18 proving no act widens to the
T03 records. Also fixes tools/exercise_t03_review_policy.py, which had been
failing since f85479c moved the T03 records to memo version 2 and it still sent
version 1. Test-only.
Not deployed: the pin serving the live review surface changes only with operator
confirmation.

# 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`.
