Merge Risk: 🟡 Moderate · up to The change adds approved-policy enforcement and JWT credential revocation. A few issues should be settled first: revoked token identifiers are matched without regard to which issuer revoked them, the documented feed interface omits a method the provider actually requires (so a custom feed can end up refusing all credentials), observe-mode pilots can under-report unapproved-policy refusals, and the verification run leaves a database connection open. None of these break the ordinary approved-policy flow, but the revocation matching and feed interface should be resolved before relying on this in production. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Limit the refusal claim to non-policy-change actions.
ctrlrun.policy.change is exempt from the approved-policy gate in §8.4. After an administrator deletes policy:<hash>, a new policy-change action can still run and restore the marker. Replace “every action” with “every non-policy-change action” so this residual does not contradict the recovery path.

Observe mode records policy_unapproved too late, so it loses to authority and policy denials.
Enforce mode checks the approval state at Line 1091, before _authority_result and before policy evaluation. Observe mode checks it here, inside _observe_secure. _observe_secure runs after the caller has already called observation.block(...) on two paths: the authority denial at Line 1111 and the policy denial at Line 1147. _Observation.block keeps the first reason, so the policy_unapproved reason is discarded on both paths.
Trigger: a deployment sets mode: observe with require_approved_policy=True, the policy is unapproved, and an action is also denied by authority or by a rule. Observe mode then reports would_have.blocked_reason = authority_* or the rule reason. Enforce mode would report policy_unapproved and would never evaluate authority or the policy.
Consequence: the observe-mode report undercounts policy_unapproved, which is the one fact an operator runs the pilot to learn.
Record the reason at the same position enforce mode checks it.

Do not require an undeclared refresh() method.
RevocationFeed requires only revoked(), read_at, issuers, and max_staleness. A conforming feed can perform its refresh inside revoked().
If that feed has read_at=None and a staleness bound, this code rejects every credential before it calls revoked(). The feed cannot complete its first read or recover.
Call revoked() once before the staleness decision and retain its result, or add refresh() to the protocol as a required operation.

_control_for("G21-guarded", ...) opens a second scratch store. The finally at the end of g21 closes only store, so the guarded store stays open for the rest of the run. On SQLite this leaks a connection and the database file handle; on Postgres it leaks a connection to the scratch schema that drop_scratch_schemas later tries to drop. The comment on Line 3504 already states that this store is "closed when the scenario ends", so the code and the comment disagree.

Correct the denominator regression assertion.
Line 866 establishes 11 passes and 10 not-applicable guarantees. A report that incorrectly includes not-applicable guarantees in the denominator would report 21/21. The current 20/20 check does not test that failure mode.

Item 7 of v0.8 (SPEC-v0.8 §8). The policy is the one file that decides every other decision, and until now it was changed by editing it. v0.6 made the change evidenced; this makes it approved. `ctrlrun.policy.change` is an ordinary action -- ordinary hash, ordinary effect key `policy:<hash>`, ordinary events, ordinary receipt -- which is why §8 adds no event type: v0.1 §6.2's vocabulary already describes a proposal, an approval request, a grant, a consumption and a commit. So §2, §3 and §4 apply with no second path: T363 drives an unverifiable approver, an unentitled one and the proposer approving their own change, and T364 drives M-of-N. The approval is per deployment. `hash_with_authority` folds in the effective authority and environment, so the same file in staging and prod is two hashes and two approvals. T353 pins that, and pins that comments, key order and whitespace move nothing. The name is reserved and declarable, which a first draft had backwards: a name no document may declare is a name `evaluate` answers `unknown_action` for, so every proposal is denied, no committed receipt is ever written, and a deployment requiring an approved policy denies every action for ever. T357 is the end-to-end flow that rule exists to make possible. Under require_approved_policy the policy in force must also declare its own change with `decision: approve`. T358 drives allow, deny and absent: each decides nothing, with the refusal naming the key. That closes the "write a policy whose change rule is allow" hole -- installing such a policy still needs an approval under the old one, and once installed it decides nothing. Enforcement is a keyed `get_effect`, never a receipts() scan, and T362 counts store calls to prove it. It also drives **both** cache transitions on one long-lived Control: a negative answer is re-asked, so an approval landing later works with no restart; a positive one is cached, so deleting the effect row underneath a running process does not stop it. That second half is §8.6's residual, asserted rather than assumed -- a test driving only the first would leave the sentence unchecked in the direction that overclaims. The replay writes nothing (T366 compares receipts, events and effects) and carries no verdict vocabulary (T367 asserts eleven words by name). G21 grades with the flag set by verify, under a note: whether a deployment sets it is a fact about its own code. Both shipped examples now report 17/17 and 11/11. 3921 tests, 3m25s, plus 56 serial.

Nine mutations, one per MUST of §8. Six were caught by the tests as written; three were not, and two of those were real gaps rather than equivalent mutants. M1 an unapproved policy decides nothing caught T354, T358 M2 the policy must declare its own change caught T358 M3 the approval is a committed keyed effect caught T354 M4 the exemption is one action, by name caught T360 M5 the reserved name needs the flow's marker caught T359 M6 a positive answer cached, a negative not caught T362 M7 nothing else may name the reserved action GAP -> test written M8 the replay writes nothing equivalent mutant, redone M9 approving_actions is all-of, not any-of GAP -> test written M7: deleting `_reject_reserved_elsewhere` broke nothing, so nothing covered the rule at all. That rule is what stops an action rendering `policy:<hash>` as its effect key, which would mint the marker of an approved policy from an action nobody reviewed as one. Three cases now drive it. M8 was my mutant's fault, not a gap: `put_receipt if False else None` writes nothing. Redone as a real write, and caught. M9: `all` -> `any` in `approving_actions` changed nothing, because the test covering it was refused by the *effect* check before the declaration rule was reached, so it passed under both. Rewritten around what actually happens, and it is sharper for it: a change rule of `[approve above 1000, allow otherwise]` is ignored on the change action's own arguments, which carry no `amount`, so the proposal commits **with nobody having answered anything** and mints the effect. The declaration rule is then the only thing still refusing, which is what `all` buys and `any` gives away. `_approved` also took the base policy rather than the control's own, so a test using it approved a hash that control never enforces. It now defaults to `control.policy`. 3931 tests, 3m32s, plus 56 serial. Signed-off-by: arpan <contact@arpanghoshal.com>
Four BLOCKING findings, and the first two mean §8.2.1's two rules were both
enforceable in principle and enforced nowhere that mattered.
1. The exemption was taken BEFORE the declaration check.
`_require_approved` returned early for `ctrlrun.policy.change`, so "the
policy in force must declare its own change with decision: approve" applied
to every action except the policy change. From a cold store: P1 declares
`ctrlrun.policy.change: {decision: allow}`; proposing a **different** policy
P2 commits with no approval and no approver; P2 declares the change as an
approval and the deployment under it finds a committed marker and decides
normally. Nobody approved P2 at all, and §8.6's stated property was false in
exactly the case §8.2.1 exists to close.
The exemption now covers the marker check only. The test covering this
before proposed the policy already in force, where the declaration branch
happens to catch it; proposing a different one is the attack, and T358 now
drives it.
2. The marker was mintable by any allowed action, three ways.
The loader tested the raw template; the key that reaches commit_effect is
expanded from agent-supplied arguments and was never re-checked. So
`effect: "{scheme}:{ref}"` with scheme="policy" mints an approved-policy
marker from an ordinary action, `"{p}olicy:{ref}"` evades the literal check
outright, and `execute(action, executor, "policy:<hash>")` needs no template
at all because effect_key is a public parameter. A reviewer approving such a
policy has no way to see that it hands every agent the power to approve
arbitrary successors.
One rule on the **resolved** key in `execute` closes all three; the loader
check stays as a convenience that names the mistake earlier. Three tests,
one per vector.
3. Observe mode minted the marker with no human, and separately refused.
Observe mode requests no approval and still reserves and commits, so a
proposal made while observing minted a real marker -- and observe-then-
enforce is the documented adoption path, so every hash proposed during the
observe phase was pre-approved for the enforce phase. Proposing under
`mode: observe` is now refused outright. The mirror image was the same
missing branch: `_require_approved` raised ActionDenied while observing,
which contradicts v0.3 §6.2 and made `policy_unapproved` a
would_have.blocked_reason §11.1 lists and the code could never produce. It
is recorded now, and is in a stats bucket.
4. (item 6, already merged) A feed past max_staleness never refreshed again.
`refresh()` was reachable only from `revoked()`, and the provider raised on
`stale()` before calling it. PollingRevocationFeed starts with read_at=None,
so with any bound set it was stale on the first resolution, refused every
credential for ever, and made **zero** HTTP polls. The file feed recovered
from nothing. Refresh now runs before the staleness test, and the staleness
warning is once per episode rather than once per action.
And the rest:
- G21 passed with §8.4's enforcement deleted: the guarded control used the
operator's document, which does not declare the change action, so the
declaration branch short-circuited and the effect branch -- what G21's
title is about -- was never reached. Verify now gives it a document that
declares one, and deleting the effect check makes G21 FAIL with "an action
ran under a policy nobody approved".
- T368 asserted `limit=0 == []`, exercising none of the skip branch, and
§8.5's unknown-schema rule was not implemented: from_dict does not raise on
one, so such a receipt was silently graded. Both fixed.
- `--last 0` answered "no recorded decision changes", a verdict about the
policy for an input that read nothing. Refused.
- `ctrlrun policy propose --as` made the proposer an assertion: propose as
somebody else, approve with your own credential, and §4.1 sees two
principals. Removed, for the reason break-glass has no --as.
- §8.4 and §8.6 said deleting the effect row is recorded as a chain break.
It is not: the chain is over receipts. Corrected rather than dropped, and
§8.6 gains the resumed-continuation row, because "refuses every action" is
true of every new action and not of a resumption in flight.

The definition of done requires at least one shipped document to exercise the
milestone's own paths, so G17 and G19 are not N/A on everything this
repository ships. examples/authority/payments.yaml now declares a control with
an approver_role and a threshold of two, and moves to ctrlrun.policy/v6.
Doing that found a real bug: `ctrlrun verify` exited 3 with an internal error
on a valid v6 document that declares `approvals_required`. Every scenario
builds its own Control, none configured an approver identity, and §4.2 denies
a threshold above one where nobody is verified -- so a threshold in an
operator's policy crashed verify on guarantees that have nothing to do with
approvals. Three things fix it:
- verify supplies an approver identity where the **document** asks for a
threshold or names a role, for §11.7's reason and no other: whether the
operator configured one is a fact about their code. A document asking for
neither keeps the 0.7.0 shape, so each guarantee is still graded against
the deployment shape it was written for.
- every scenario that grants now grants to the **request's** pinned
threshold, with that many distinct verified principals. The request's and
not the policy's: they differ where a scenario built its own request, and
the store enforces the pinned one -- reading the policy granted twice
against a row needing once and met "already granted".
- G7's grant went through `grant_approval` directly, so the moment an
identity was configured it failed `approver_unverified` -- G7 reporting a
failure about G17. It uses the same helper now.
examples/authority/payments.yaml: 19/19, 2 not applicable (G13, G15), from
17/17 and 4. The templates example is unchanged at 11/11.
`test_each_authority_example_declares_v3` pinned the exact schema, which made
this impossible; it now requires v3 **or later** and says why an exact pin
would have to be relaxed by whichever milestone shipped a newer key. And the
example's own comment used the word "compliance" while explaining that no such
claim is made, which `test_no_authority_example_makes_a_compliance_claim`
caught -- correctly.
