Build-list item 2 of v0.8, docs/SPEC-v0.8.md §2 and §4.1. Tests T281 to T297. Three rounds of independent review, and the design changed twice because of them.

Approval.approver is a string whose only check is that it is not empty, and adapter.py has always conceded what that string often is: a channel, wherever the framework's primitive does not identify a person. A deployment may now name an ApproverIdentity, and where one is named an approval is consumable only if the store holds a VerifiedApprover for it.

Opt in, then fail closed

SPEC-v0.3.md §1.2's rule for authority, applied to the approver. Without one: 0.7.0 exactly, asserted field by field across the whole approve-and-execute path (T282). With one: no partial mode. An approval whose row carries no verified approver is refused, including one granted before the provider was configured (T295), one granted through a surface that cannot resolve, and one held by a store that ignores the column.

Which surfaces can produce a verified approver is narrower than the feature's name suggests, and §2.6's table says so before anyone configures this. The operator MCP server can, and now does: it has resolved a principal for every request since it shipped and then discarded it into mcp-operator:<user>, so on that surface this item is four lines that stop discarding it. An embedding application can. ctrlrun approve, the webhook and the adapters cannot.

The gate took three attempts, and §2.4.2 records all three

This is the part worth reading.

  1. Skipping the lapsed row was fail-open. The first design stood aside whenever this clock considered the grant lapsed, because refusing there would cost the lapse its APPROVAL_EXPIRED event and the store's own lapse write. But a skip is permanent and the store keeps its own clock: on a host running ahead, the checks stood aside, consume_approval_and_reserve consumed the grant by the store's clock, and the action ran with no approver check at all. The review reproduced it as a self-approval committing under a twenty-minute skew, on the path §2.4 calls every deployment that does not use v0.7 §6. It is v0.7 §12.5's divergence inverted from "safe and untrue" into fail-open.

  2. Deferring it past _take closed that and moved the damage. consume_approval_and_reserve does both halves of v0.1 §4.2 A4 in one transaction, so a refusal after it left a consumed grant, an effect key RESERVED with a live lease and nothing to release it, no EFFECT_RESERVED and no APPROVAL_CONSUMED event, and a receipt whose error said the approval was left granted when it was not. The key lapses into AMBIGUOUS: a human resolving an action the kernel itself refused and which provably never ran. There is no clean cleanup either, fail_effect requires EXECUTING so RESERVED → FAILED does not exist, and mark_ambiguous would assert "unknown" about an action known not to have run.

  3. Checking it before _take, like every other row, is the answer. The cost is one narrow case: a grant that is both lapsed and approver-refused keeps no APPROVAL_EXPIRED and no lapse write. What it buys is that nothing is written by a refusal stays literally true, which neither other answer could say.

T291c is the skew reproduction and asserts the grant is still granted and nothing reserved, which its first version did not and so could not tell a refusal before _take from one after.

What the review found that no test would have

  • would_have.blocked_reason is a closed vocabulary because ctrlrun stats buckets counts on it. Recording each mismatch's own reason (§4.1's change) made an observe-mode approval refusal land in no bucket at all: would_have_been_blocked went 1 to 0, and nothing went red, because the only assertions on that field use an effect-state reason. receipt.py's own comment had warned that a bucketed count over a string nobody constrained is a report that quietly stops adding up.
  • And that bucket was already missing a human's no. check_consumable catches a denied record one branch earlier and records approval_denied, which was in no bucket. That predates v0.8; it is fixed here because this commit writes the set and argues for closing exactly this.
  • A resumed leg's receipt dropped the approvers, and that leg is the only receipt an MCP multi round-trip or an ACS action ever gets (SPEC-mcp-operator.md §8.3).
  • A corrupted approvers column threw a raw JSONDecodeError out of execute. It is a named CTRLRunError now, while Receipt._approvers_of keeps the opposite rule, because a receipt is evidence a reader walks past and one tampered row must not blind every reader.
  • My test file covered one store. Blanking the verified approver in the SQLite write path left all twenty tests green. The fixture runs on three stores now.

Mutation table

Fourteen, each with PYTHONDONTWRITEBYTECODE=1 and src/**/__pycache__ cleared. All RED (caught): the refusal, the opt-in switch, the gate, the lapsed row skipped again, self-approval, comparing the string instead of the principal, the early return restored, both stores' write paths, the operator server discarding the principal, observe mode not checking, observe mode recording the constant, the stats bucket dropping the approval reasons, and a resumed leg dropping the approvers.

Verification

  • Local gate with Postgres: 3651 passed, all checks passed. Baseline at 67f2563 is 3574.
  • ctrlrun.receipt/v5, ctrlrun.policy untouched, ctrlrun.guarantees/v4, migration 0006_verified_approver, each moving once, with the whole v5 shape frozen so items 4 and 5 fill it without a second bump.
  • Twelve test files outside this item changed, every edit a count or key set true of 0.7.0 and not now. The verify counts are also pinned in .github/workflows/ci.yml, which would have turned that job red on a branch whose suite was green.
  • Docs generators drifting: cli, schemas, api, readiness. Item 8 regenerates them.

Summary by CodeRabbit

  • New Features

    • Added optional approver identity verification for deployments.
    • Approvals record verified approver details and reject unverified or self-approved requests.
    • Observe mode reports specific approval mismatch reasons.
    • Added guarantee G18: requesters cannot approve their own actions.
    • Receipts now use schema v5 and include approver information.
  • Bug Fixes

    • Improved approval checks for expired, pending, denied, consumed, and unknown requests.
  • Documentation

    • Updated the v0.8 specification and changelog.
  • Chores

    • Added database migration support for verified approver data.

Approval.approver is a string whose only check is that it is not empty, and
adapter.py has always conceded what that string often is: a channel, wherever
the framework's primitive does not identify a person. A deployment may now name
an ApproverIdentity, and where one is named an approval is consumable only if
the store holds a VerifiedApprover for it.

Opt in, then fail closed, which is v0.3 §1.2's rule for authority applied to
the approver. Without one, 0.7.0 exactly, asserted field by field across the
whole approve-and-execute path. With one, no partial mode: an approval whose
row carries no verified approver is refused, including one granted before the
provider was configured, one granted through a surface that cannot resolve, and
one held by a store that ignores the column.

The check lives at the consumption because Control never grants an approval.
Two things about that seam, both of which the spec review found before any code
existed and both of which building it confirmed. _recheck returned early on
every deployment not using preconditions, so a check added after that return
would have been dead on the default path, green, and invisible to a mutation
table. And the check is gated on a record that is granted and not lapsed by
this clock, using check_consumable's own verdict: without the gate a denied
approval reports approver_unverified, so a human's no stops appearing in the
evidence as a no, and G1, G2 and the lapse write go with it.

G18 grades the refusal of a self-approval, compared on the resolved principal
and never on the string. Verify supplies the approver identity it grades
against: whether an operator configured one is a fact about their application,
which verify cannot see and which its own module forbids as an N/A reason.

The operator MCP server is the one shipped surface that can produce a verified
approver, and it has resolved a principal for every request since it shipped
and then discarded it into mcp-operator:<user>. Four lines stop discarding it.
ctrlrun approve, the webhook and the adapters cannot, and SPEC-v0.8 §2.6 is the
table that says so before anyone configures this.

Needs ctrlrun.receipt/v5 and ctrlrun.guarantees/v4, each moving once, and
migration 0006_verified_approver across all three stores, with approvers
COLLATE "C" on Postgres because item 4 makes it a compare-and-set column.

Eighteen tests outside this item moved, each a count or key set true of 0.7.0
and not now, and §14.2 lists them. The verify counts are pinned in
.github/workflows/ci.yml as well, which would have turned that job red on a
branch whose suite was green.

…t did not exist

Two blocking, nine smaller, and the first is the worst defect this milestone has
produced so far.

The gate stood aside whenever THIS clock called the grant lapsed, because
refusing there would cost the lapse its APPROVAL_EXPIRED event and the store's
own lapse write. A skip is permanent and the store keeps its own clock: with
this host running ahead, the gate stood aside, consume_approval_and_reserve
consumed the grant by the store's clock, and the action ran with no approver
check at all. The reviewer reproduced it as a self-approval committing under a
twenty-minute skew, on the 0.6-shaped path §2.4 calls every deployment. That is
v0.7 §12.5's divergence inverted from safe-and-untrue into fail-open.

So the lapsed row is a deferral. Where the store disagrees and consumes a grant
this clock called lapsed, §2.7 and §4.1 run on the record the presenting pass
read and refuse; the grant is spent in that branch, which happens only where
clocks already disagree, and spent-and-refused is the fail-closed direction.
T291c is the reproduction and M3b and M3c are its mutations. The verdict is
also computed once now, from one clock read, which §2.4.1 required and the
first version did not do.

And observe mode: §4.1 said it records approver_is_requester, _observe_take
never called the check, so it recorded nothing. The section described something
that did not exist, and T296 presented no approval at all, which made it a
negative test against behaviour its own setup prevented. The check runs there
now, _observe_secure records the mismatch's own reason where it recorded one
constant for every mismatch, and T296 asserts both. That vocabulary change
reaches refusals with nothing to do with v0.8, which the changelog says and
which test_observe_mode_rechecks_records_and_runs_spending_no_grant now shows:
a precondition refusal that used to read approval_mismatch reads
precondition_changed.

Smaller: a resumed leg's receipt dropped the approvers, and that leg is the
only receipt an MCP multi round-trip or an ACS action ever gets; a corrupted
approvers column threw a raw JSONDecodeError out of execute, and is now a named
CTRLRunError, while the receipt reader keeps its never-raises contract for the
opposite reason; verified_approver_now was a public name outside §11.1 and is
now underscored; the static-provider warning compared a type name as a string,
on the very shape §4.1 exists to refuse; §2.8 claimed a contract nothing calls,
and now says item 3 wires it; T290, T292 and T293 asserted less than they
claimed, and T292 and T293 now name where the real coverage lives.

Fourteen mutations, all caught.

…ow is checked

Three blocking, two of them defects introduced by round one's fixes, which is
the shape CONTRIBUTING asks a second pass for.

The deferral closed the fail-open and moved the damage. consume_approval_and
_reserve does both halves of v0.1 §4.2 A4 in one transaction, so a refusal after
it left a consumed grant, an effect key RESERVED with a live lease and nothing
to release it, no EFFECT_RESERVED and no APPROVAL_CONSUMED event, and a receipt
whose error said the approval was left granted when it was not. The key lapses
into AMBIGUOUS: a human resolving an action the kernel itself refused and which
provably never ran, which is the shape _spend_unneeded_approval already records
a review finding for. There is no clean cleanup either: fail_effect requires
EXECUTING so RESERVED to FAILED does not exist, and mark_ambiguous would assert
unknown about an action known not to have run.

So the lapsed row is checked before _take like every other row. verdict.expire
is read rather than discarded. The cost is one narrow case, a grant that is both
lapsed and approver-refused keeps no APPROVAL_EXPIRED and no lapse write, and
what it buys is that nothing is written by a refusal stays literally true, which
neither the skip nor the deferral could say. §2.4.2 records all three attempts
because the next reader will reach for one of the two wrong ones.

§2.4.1 still specified the design the review rejected. Only the retrospective
§14.2 had been updated, so a reader implementing from the normative section, or
a third-party Control, would have built the skip. §2.4, §2.4.1, §2.4.2 and §12
now describe what the code does.

And the observe-mode vocabulary change had a consumer nobody had looked at.
would_have.blocked_reason is a closed set because ctrlrun stats buckets counts
on it, and receipt.py says a bucketed count over a string nobody constrained is
a report that quietly stops adding up. Recording each mismatch's own reason made
that true: an observe-mode approval refusal landed in no bucket,
would_have_been_blocked went from 1 to 0, and nothing in the suite went red
because the only assertions on that field use an effect-state reason.
BLOCKED_BY_STATE grew with the change and T296b asserts the count, driven with
no ApproverIdentity anywhere because the receipt that stopped counting was a
plain hash mismatch.

Smaller: T291c now asserts the grant is still granted and nothing reserved, so
it can tell a refusal before _take from one after; mismatch.reason or the
constant was a subsumed guard, since reason is a required keyword; §2.4 says
what observe mode's refusal costs a reservation; and the deferral's dead flag,
its post-take read and the InvalidArgument that could escape through it are all
gone with it.

Fourteen mutations, all caught. 3645 passed.

…aphs I dropped

Nothing blocking survived. Five smaller findings, and one of them is older than
this milestone.

check_consumable catches a denied record one branch before the generic status
branch, so what observe mode records for it is approval_denied and not denied.
The set this item introduced carried "denied", which nothing on that path can
produce, and missed "approval_denied", which is recorded: an observe-mode run
where a human refused was counted in no bucket at all, which is close to the
most important thing such a report can say. That predates v0.8. It is fixed here
because this is the commit that writes the set and argues at length for closing
exactly this, and shipping it wrong would have made the argument false on its
own terms. T296b's sibling drives a human's denial through observe mode.

The gate's fourth row, pending or no such approval, had no test, and §2.4.2
claimed T291b covered it. It does now, both values, and pending is the reason
§2.7's fifth row and all of item 4's M-of-N depend on: a gate narrowed to
exclude it would have gone unnoticed and taken M-of-N's refusal with it.

record.approvers if record is not None else () was a subsumed guard: control
reaches it only where verdict.record carries the record or verdict.expire is
set, which check_consumable can only reach after record is None has returned.
An assertion says so instead of an else branch pretending a case exists.

"Every refusal in §2 and §4 is raised before _take" was wider than the
mechanism: §2.7's fifth row is the store's own pending, raised inside _take,
which is where it belongs.

And five paragraphs of §14.2 went missing in the round-three rewrite, including
the only record of the .github/workflows/ci.yml verify-count pin, which that
paragraph itself describes as something nothing in the local gate would have
caught. Restored, with the bucket finding beside them.

Fourteen mutations, all caught. 3651 passed.

Remove the unused store and clock fixtures from both T287 tests.

ApproverIdentity.resolve is the only operation in these tests. The parametrized store fixture therefore repeats each test for in-memory, SQLite, and PostgreSQL stores. When CTRLRUN_TEST_POSTGRES is set, each unnecessary PostgreSQL run also creates and drops a schema.

Validate entitled before converting it to a tuple

_approvers_from_json passes stored approver mappings to VerifiedApprover.from_dict. A string such as "abc" currently becomes ("a", "b", "c"), so the corrupted approval row is accepted instead of raising the documented CTRLRunError (InvalidArgument). Validate the raw value before conversion, while preserving an omitted or null value as empty:

string was therefore accepted as an approver entitled for three controls that do
not exist, silently, and _approvers_from_json's promise to raise on a corrupted
row was false for exactly the shape a corruption most easily takes. entitled is
now validated before conversion, as a list of non-empty strings, read as object
because the declared type is what a caller promises and this value comes from a
JSON column. T283b drives the four shapes.

That is the same hazard SPEC-v0.8 §3.4 states for the roles claim, which the
independent review made me write into the spec and which then landed in the code
one field over.

The other four are accuracy. The changelog said verify grades sixteen
guarantees; the catalogue is G1 to G16 plus G18, which is seventeen. §2.4 said
nothing is written by a refusal and then described the event and receipt it
writes: it now says no approval is mutated and no effect reserved, and that
evidence is written, because a refusal nobody can find afterwards is not a
refusal this project ships. §2.4.1 merged the pending and unknown rows, which
carry different reasons and have separate tests. And §14.2 listed
Control._withdraw among grant_approval's callers when it calls deny_approval,
which §2.6's table already gives its own row.

3654 passed.

CodeRabbit found five, and one was a data-integrity bug rather than a wording fix

73fb387.

str is a Sequence. VerifiedApprover.from_dict did tuple(document.get("entitled") or ()), so a corrupted column holding "abc" became ("a", "b", "c"): an approver silently entitled for three controls that do not exist, and _approvers_from_json's promise to raise on a corrupted row was false for exactly the shape a corruption most easily takes. entitled is now validated before conversion, and T283b drives the four shapes.

Worth naming: this is the same hazard the independent review made me write into SPEC-v0.8.md §3.4 for the roles claim. It was caught there in the spec, and then landed in the code one field over.

The other four are accuracy, all correct:

  • The changelog said ctrlrun verify grades sixteen guarantees. The catalogue is G1 to G16 plus G18, which is seventeen.
  • §2.4 said "nothing is written by a refusal" and then described the APPROVAL_INVALIDATED event and BLOCKED receipt it writes. It now says no approval is mutated and no effect reserved, and that evidence is written, because a refusal nobody can find afterwards is not a refusal this project ships.
  • §2.4.1 merged the pending and "no such approval" rows, which carry different reasons (pending and unknown) and already have separate assertions in T291b.
  • §14.2 listed Control._withdraw among grant_approval's callers; it calls deny_approval, and §2.6's table already gives it its own row.

Local gate: 3654 passed, all checks passed.

CI

All fourteen required checks pass on the previous head, including check on 3.11 to 3.14, package, verify and fuzz. The only red is docs, which is not a required check, and it fails on cli.mdx drift from item 1's two new options plus this item's schema and API additions. Item 8 regenerates all of it in ctrlrun-docs; main has the same job red for the same class of reason.

five non-lapsed store-owned rows—denied, consumed, hash-moved, pending, and no
such approval—replacing “all four” and “the four rows above”; exclude the lapsed
row from that count and retain it as a separate additional case.

Comment thread docs/SPEC-v0.8.md
Splitting the pending and unknown rows made §2.4.1's store-owned set five, and
the prose around it still said four. CodeRabbit caught the count; fixing it
showed that §10.2's T291b entry had drifted further than that, describing four
rows when the tests assert six and calling the lapsed row "the fourth".

§10.2 now describes what the tests do: the five store-owned rows, the lapsed
row with a good approver, and a pointer to §2.4.2 for what checking the lapsed
row costs. T291c gains its entry, including the two assertions that let it tell
a refusal before the store call from one after, and T292 and T293 say what they
cover and name T264 and T265 as the rest.
