v0.9 Envelope: consumption and holds, the operator surfaces, and the 0.9.0 release - #164
Merged

Conversation
SPEC-v0.9 §4. A budgeted grant charges every ancestor on reserve, and the ledger is released exactly when the effect reaches FAILED. §4.2's table has nineteen rows and the implementation has one rule, because plan_reservation is already the complete table of exits from a reservation and the ledger needs an invariant rather than a state machine. COMMITTED holds permanently. AMBIGUOUS holds until a human or a hook moves it, which is R2: an agent that can generate ambiguity must not thereby generate authority. A lapsed lease holds because no transition has occurred. Only FAILED releases, because that is the one state in which the executor proved nothing happened. Keyed on the state REACHED, never on the call that reached it, which is §4.2's own warning: a fail_effect that is refused because the record moved on releases nothing, and a human's resolve_effect(FAILED) releases even though no fail_effect ran. The release lives inside the transition, so the ledger moves with the record or neither moves. A compare-and-set on released_at, never a decrement: v0.6 §4.3.2 Table A2 row 2 re-issues a lost UPDATE once, and a decrement would subtract twice. §2.7's per-ancestor charging is what makes the feature mean anything. Without it a holder of a 100,000-a-day grant delegates ten correctly contained children and spends 1,000,000: every link individually valid, the total ten times what anybody granted. §2.4.1's refusal landed where the effect key is finally known, which is the third place it has been and the one the probes in that section point at: a loader cannot see a decorator-supplied effect=, and cannot run at all on the standalone-authority path. BudgetExhaustedError gets its own except clause before the ActionDenied one, for the reason item 2 met first with the scope refusal: that handler appends APPROVAL_DENIED unconditionally and would fabricate an approval denial for an action no human saw. The shipped example's budget is resized and the comment says why. A budget bounds the aggregate; the constraint beside it bounds one action. The first version was €1,000 a day under a band permitting €100,000 per refund, so the first refund of the day exhausted it, which is legal and almost always a mistake. It is €500,000 a day now, and the comment says that out loud because the example teaches. Signed-off-by: arpan <contact@arpanghoshal.com>
SPEC-v0.9 §4.1, §8. ctrlrun verify now reports 22/22 on the shipped examples with G22, G23 and G24 all passing. Writing G22's scenario found a real defect. resolve_effect does NOT go through _transition on any of the three backends, so the release written there never fired for it: a human resolving an AMBIGUOUS record FAILED held the charge for ever. That is the one act meant to free a hold doing the opposite, and it is the act R2 names as the way out. Found only because the scenario tried to free its own hold; the unit tests released through fail_effect, which does go through _transition. T419 pins it and says why. G22 grades both halves. The control is that a budget with room lets the action run, without which a kernel refusing everything grades PASS. The subject is the hold: one reservation takes the rest of the budget, goes AMBIGUOUS, and the next action is refused budget_exhausted. Then resolve_effect(FAILED) gives the room back, which a kernel that never released would otherwise pass everything above. One reservation rather than a fill loop, so the scenario costs the same against a budget of 500 and one of 500,000,000. And the selection is nudged to spend at least 1: select picks the first rule a document admits, a band beginning at zero gives an amount of zero, and a budget that never moves would let every assertion pass against a kernel that does not charge at all. §2.4.1's refusal moved once more, and this is where the probes said it belongs: _secure returns early for an action with no approval and no effect key, so the charge assembly had to happen BEFORE that return or the kernel declines to notice the case the rule is about. budget_charges lands on ctrlrun.receipt/v6, one entry per ancestor charged, so a reader can tell an action that spent a child's budget from one that spent a root's. All three v6 fields are now written by something, which item 7 asserts before the release. The authority badge moves 21/21 to 22/22 and the templates example's N/A count 12 to 13. Signed-off-by: arpan <contact@arpanghoshal.com>
§2.7's per-ancestor charging is the rule that makes budgets mean anything, and removing the ancestor walk left 84 tests green: nothing drove a real delegation chain through Control. T412b does, and asserts the parent's budget is what refuses even though the child is within its own. And the missing-metric-argument guard was subsumed. With it removed, None falls through to the non-integer check and raises anyway, so T441 passed for a reason that was not the rule. The pattern list allows keeping a subsumed branch for its message on one condition, that a test asserts which message it got, so T441 now does. Signed-off-by: arpan <contact@arpanghoshal.com>

_refuse_budget drops the effect key from its event and receipt.
self._append and self._record here do not pass effect_key, so the ACTION_DENIED event and the DENIED receipt for a budget-exhausted refusal both carry effect_key=None, even though this refusal only fires for an action that resolved a real effect key (§2.4.1 already refuses a budgeted grant with no key, earlier). Other DENY branches in _secure's loop, such as the ActionDenied handler, explicitly pass effect_key=effect_key.
This weakens traceability: an operator correlating this denial with the effect/idempotency key it applied to has to fall back to action_id instead.
Pass effect_key through to _refuse_budget and forward it on both calls.

Calculate the held amount separately for each charge.
charges can contain multiple grant and ancestor budgets with different per-action amounts. Subtracting the selected budget's per_action from every limit can create a negative charge or make reserve_effect reject an otherwise valid configuration.

Approve each subsequent action when the selection requires approval.
select() can return Decision.APPROVE. Only the positive control creates an approval. The blocked attempt can stop at the approval gate instead of the budget gate, and the final attempt cannot commit after the hold is released.
Call self.approve(...) for both later and freed, as the other retry scenarios do.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Advance the clock so T421 can detect a moved released_at.
The clock fixture is frozen for the whole test. _release_locked writes now on both passes, so first and again are equal even if the second release overwrote the timestamp. The assertion passes for a reason that is not the compare-and-set on released_at.
Advance the clock between the two failures. Then a second write would produce a different timestamp and the assertion would fail.
Note also that the second reserve_effect renews at attempt 2 and writes its own ledger row, so next(...) reads attempt 1's row. That is the row under test, so the ordering is correct; only the frozen clock weakens it.

§4.2's table has nineteen rows; twelve had no test. A review moved the release above the state check in the in-memory _transition, keying it on the call rather than the state reached, and the whole suite stayed green: a refused fail_effect then released the hold on an AMBIGUOUS record, which is the manufacturable refund this item exists to stop. T425 pins the rule as the spec states it. T422, T423, T424, T427 and T428 cover the dispositions that carried no test, including a suspension outliving its own budget window. T406a is §2.2's own motivating shape, two budgets on one metric, which the duplicate-charge guard refused until now; T406b keeps the guard for the hazard it is actually for, two charges on one metric with differing amounts, which §3.4's key would silently collapse. Signed-off-by: arpan <contact@arpanghoshal.com>
…re relies on Six more rows had no test: the ceiling refusing after the reservation was won (the shape v0.8's item 4 missed, and with it the reconcile-hook and second-take rows), begin_execution refused after the reservation was won, mark_ambiguous refused, and a refused retry. T429 drives the ceiling route through the public API, so the reconcile hook releases the ambiguous charge, the renewal takes a fresh one, and the kernel's own fail_effect releases that: four charges, none held. T432 corrects a drafting assumption, a refused retry raises rather than answering from the record; what §4.2 asks is only that the ledger is unmoved. The in-memory _transition now says why its order is load-bearing. Both SQL stores roll the transition back when the state check raises, so there the order is equivalent; the in-memory store mutates a dict under a lock and has no rollback, so the order is the atomicity. Signed-off-by: arpan <contact@arpanghoshal.com>
…oval gate Both escaped as a bare InvalidArgument: no ACTION_DENIED, no receipt, nothing in the one record an operator has of a refused action. They now go through _refuse_unmeasurable, which writes the event and a denied receipt and returns the error for the call site to raise. The exception type is unchanged; neither of these is a budget running out, and §2.3 pins it. Two reasons rather than one. An operator who declared a budget on an action with no effect: template has a different thing to fix than one whose agent proposed a negative amount. The charge assembly also moves above the approval gate. Neither refusal depends on anything the gate produces and both are unconditional, so running them after it asks a human to approve a refund the kernel has already decided to refuse, and leaves a granted approval behind for an action nothing can execute. A probe found APPROVAL_REQUESTED written for that shape; T446 pins it shut. Signed-off-by: arpan <contact@arpanghoshal.com>
…edger resume never touched _BUDGET_CHARGES, so budget_charges on the resumed receipt came from whatever the contextvar happened to hold. §8.3 makes that receipt the only one an MCP multi round-trip or ACS action ever gets, and both ways of getting it wrong are live: a gateway that restarted mid-round has an empty contextvar and reported no charges for an action that spent, and a gateway that ran another action in this context since the suspension reported that action's spend on this action's receipt. The ledger is the record, written by the first leg inside the reservation's own transaction, so the resumed leg reads it. consumptions() gains an effect_key filter for that read; without one it is a scan of the whole ledger per resumption. §4.3 gives a renewal a new charge, so the read is filtered to the attempt the resumption is actually on, or the receipt would add an already-released spend to the one it holds and claim double. T450 pins that; removing the filter fails it on all three backends. T447 resumes inside a fresh contextvars.Context, because a continuation exists for a gateway that restarted and a test that reuses the caller's context is testing the case that works.

Observe mode charged nothing, which was right, and reported nothing, which was the half that did not exist. It now evaluates §3.3.1's predicate against the ledger as it stands and records what would have happened, writing nothing. The predicate is check_charges, the same function all three stores enforce with, so the report and the enforcement cannot drift: a pilot that says this would have been fine about an action enforce mode refuses is worse than no pilot. §2.3's and §2.4.1's refusals are reported the same way, under their own reasons rather than budget_exhausted. Enforce mode refuses those actions, so saying so is what observe mode is for, and an operator needs to know whether the budget is too small or the action cannot be measured at all. They write no denied receipt under observation, which routing them through _refuse_unmeasurable unguarded would have done: two receipts for one action, disagreeing. §4.2.1 claimed this is how an operator sizes a budget before turning it on. It was not. Observe mode charges nothing, so a deployment observing every action has an empty ledger and the report says no budget would refuse anything however much the agent proposes. 4.2.1a states that limit, and observed receipts now carry the counterfactual charge, which is the number the sizing question actually needs and which a probe found to be an empty tuple.

_synthesize picks an action vector to land in a rule, and a grant whose budget is smaller than that vector refuses the action before the guarantee is reached. Verify reported that as an internal error, exit 3, on guarantees with nothing to do with budgets: a €1,000 daily budget under a policy admitting a €100,000 refund failed G1, which is about approvals. That is _identity_the_document_needs's case one dimension over, and it gets the same answer. Verify owns the vector, so verify sizes it: where a budget would refuse the synthesized action, the smallest value that lands in the same rule with the same reason is used instead, which leaves the most headroom for a scenario that acts more than once. The vector is only resized when a budget would refuse it, so every document without budgets keeps the selection it had, and T413b pins that. Where no value fits, the candidate is declined and the guarantee reports N/A. That needed its own reason: falling through to the grant miss told an operator no grant's resources: matched, about a document whose patterns matched perfectly, which is the category error unselected's own docstring exists about. A budget smaller than any single action in a band makes that band unreachable, and NO_ACTION_FITS_THE_BUDGET says so and names the action and the grant. examples/authority/payments.yaml keeps its €500,000 daily budget. Its amount_lte admits a €100,000 single refund and its approve band runs to €10,000, so €1,000 a day would make every human-approval path unreachable, which is the mistake the file's own comment warns about. The widening was the right number, not a workaround; verify not crashing on the wrong one is a separate defect, fixed here. Signed-off-by: arpan <contact@arpanghoshal.com>

SPEC-v0.9 §7. What v0.9 built has to be visible to the person who gets paged, and visible without a management plane. No new command, per §7.1: a new command is a surface this project keeps forever, and the question here is not a new one. ctrlrun inspect --grant reports each budget as consumed, held and why, and the third is the deliverable. A budget that refuses while it looks nowhere near its limit is almost always one unresolved effect, and without the third column an operator cannot get from the refusal to ctrlrun resolve. The view prints that command with the effect key already in it: retyping it from the line above is one transcription away from resolving a different effect. T434b drives the whole path, refusal to cleared, rather than trusting it. ctrlrun effects says what each effect is holding, so --state ambiguous answers what is pinning this grant. It says spent for a committed effect and holds for every other, because §7.2 defines held as the part that has not committed and one word for two numbers would make the two commands disagree about what they are showing. ctrlrun stats reports the ledger row count, §7.3's observability half. The count is produced in ctrlrun.reporting rather than in either caller: SPEC-mcp-operator §9.1 gives one document one producer, and a key the CLI reported and the operator server did not was two shapes under one schema name. T193 caught exactly that. A ledger row whose effect record is gone is reported held with a null state rather than skipped. §7.3 permits archiving rows the window can no longer reach, and a store whose effects were pruned but whose ledger was not must not under-report held: that is the one direction this view may not err in, because it is the direction that hides a hold.

§10's rule is that anything not in that section is a spec amendment before it is code, so consumptions()'s effect_key filter and ctrlrun.budget/v1 are written down rather than slipped in. Each row says why an existing name could not serve: the resumed leg knows its effect key and not which grants a chain of ancestors charged, and an inspection document that answered about an action and a grant under one schema name would have to be told apart by its reader.

One subsection per item, from the CHANGELOG lines each left when it landed, in SPEC-v0.4 §12 through SPEC-v0.8 §14's format. §13.0 is the milestone's own entry, and it is the one worth reading first. Every design claim this document made about its own code had to be probed, and the ones that were not were wrong about a third of the time: across three review rounds every citation was accurate and roughly three design claims per round were false. The accurate half is always 'this line says X' and the unreliable half is always 'therefore Y happens at runtime'. The second-order version cost more: a green test is not evidence that the guard it covers is load-bearing, which items 2, 4 and 5 each learned by mutation.

DIMENSIONS was written as seven when item 1 added tasks; item 3 added budgets and made it eight, which is what the exported constant and G9's own count say.

SPEC-v0.7 §12's D27 rule, which SPEC-v0.9 §10.1 hands item 7: every field frozen before the items started is asserted written before the release PR opens. The existing field-list pins in test_demo and test_protect catch a field that was never added. They cannot catch a field present on every receipt and populated by nothing, which is a schema bumped for a feature whose write path was never wired: it reads as shipped and is not. One action carries task, scope_hash and budget_charges together, through the public API, and the serialized document is checked too because that is what an evidence consumer reads.

Version 0.9.0, the [0.9.0] CHANGELOG section, and the four things the bump moved with it. Both adapters pinned ctrlrun>=0.5,<0.9, which excludes the kernel in this repository. The range is a range rather than a floor because the adapter contract is not frozen until v1.0, so it becomes <0.10 rather than opening. Four files state it per adapter, and the packaging tests check all four against pyproject: the pin, the README, the package docstring and the kernel range CI installed. CITATION.cff carries the version too. The Stricter than 0.8.0 section lists what changed with what 0.8.0 did, and the one to read is the first: migration 0007 makes the upgrade one-way per store, because an older binary opening the migrated database refuses at open. A migration that only runs forwards turns a rollback into silent corruption, which is SPEC-v0.6 §3.5's rule and why the refusal exists.

Keep inspect --grant on the non-mutating read path.
When no store_url is provided, _inspect_grant calls _control_on(None). _control_on constructs SQLiteStateStore(state_path(policy.source)). Its constructor creates parent directories and calls migrate, so the command can create or migrate the default database.
An explicit sqlite:// URL uses _store, but _opened also constructs SQLiteStateStore. It prevents creation of an absent file but can migrate an existing database. Action-history inspect has the same SQLite migration behavior, although its _store path prevents creation.
Make the SQLite read path reject missing or non-HEAD databases before constructing the migrating store. Then build the grant inspection control from _store(store_url). Keep _control_on's create-if-absent behavior for write commands.

Count ledger rows without loading the ledger.
src/ctrlrun/reporting.py:ledger_rows() calls len(store.consumptions()). The gateway and CLI stats paths use this helper. Each consumptions() implementation reads all matching budget_ledger rows, and the durable stores call fetchall(). The ledger only grows, with no retention or pagination bound. Stats memory use, database transfer, and latency therefore grow with the ledger.
Add a count-only store operation. Use COUNT(*) in SQLite and PostgreSQL, and use len() while holding the in-memory store lock. Update ledger_rows() to use that operation.

An independent review found both, and the gateway one is the worse. The MCP gateway DROPPED THE CONNECTION. _through_control catches eight exception types and InvalidArgument is not one, so §2.3's refusal raised out of the request handler and the socket closed with no response, which that file's own comment calls the one thing this library exists to prevent. The client sees RemoteProtocolError, and a client that retries blindly gets nothing while the store takes one ACTION_DENIED and one denied receipt per attempt. It was reachable for allow-band actions before this milestone; moving the charges above the approval gate made it reachable for approve-band actions, which previously got a well-formed 403 first. The ACS hook answered -32002 malformed envelope, whose comment reads "there is no action", for an action it had just written ACTION_DENIED and a denied receipt for. The IdentityError clause directly below states the rule that breaks: an ACS answer and the evidence may not disagree about the same action. An error envelope says the Guardian could not answer, which a platform may act on however it likes; a deny says the tool must not run. Both need the reason at the boundary, so the refusal carries it. _UnmeasurableError is an InvalidArgument subclass, package-internal like _ScopeRefusedError and _ObservedRefusalError beside it, so every existing except-InvalidArgument keeps working and §2.3's pinned type does not move. The gateway answers -41001, which §11 already freezes as "not permitted to anyone in this configuration"; the ACS hook answers deny with the reason the receipt names. And observe mode disagreed with enforce mode about WHICH refusal would fire, twice. The unmeasurable check sat below the approval gate after T446 moved the enforce copy above it, so a pilot was told a human would have been asked about an action enforce refuses before anybody is asked: T446's own defect on the other side of the mode switch. The budget check sat above the take, while the store decides plan_reservation before check_charges, so a pilot was told to raise a limit when the real answer was that the effect had already happened. The check splits into _observe_charges above the gate and _observe_spend below the take, mirroring the order the kernel actually decides in. T451 and T452. T453 to T456 pin three guards a mutation run found removable with the whole suite green: the rolling window, the released-row filter and the per-grant filter in the observed sum. Each diverges the report from the decision in a different direction, and every existing test had one grant, one window and no released rows. Signed-off-by: arpan <contact@arpanghoshal.com>
Three findings from an independent review, all in the resize item 5 added, and two of them are defects that resize introduced rather than ones it failed to fix. A resize can change WHICH GRANT DECIDES. Authority.evaluate resolves min(passed, key=grant_id), so a vector shrunk to fit one grant's budget can fall inside a lexicographically earlier grant's constraints, whose budget was never looked at. Shrinking 100000 to 1 moved the action from bb-broad to aa-narrow and verify exited 3 on a budget it had not checked. Every candidate is now resolved the way the kernel resolves it, before and after the resize. A budget naming a metric the actions do not carry still exited 3. That grant refuses every action it covers, for ever, and the fitting treated an unreadable metric as a fit. It is also a different fix from a budget that is merely small, so it gets its own reason: told "exceeds a budget", an operator raises a limit that was never the problem. And a vector sized to the limit exactly made G4 report FAIL. Its control leg runs eight children on distinct keys and then contends eight more on one, so it needs nine spends to fit; sized for one, the control leg passed and the contended leg found zero winners. Verify may say it could not grade a configuration. It may not accuse the kernel of a defect, which is what FAIL means. Candidates now have to leave that much room, and where none does, N/A. The budget miss also masked the grant miss. select records a grant miss for every failed candidate, so a document with one budget-blocked action and one no grant covers at all reported only the budget and the resource miss appeared nowhere. Both are true of the document, so both are stated. T413 was a false green and is now a real test. Against ACTIONS the allow band is bounded at both ends and _synthesize picks amount: 0, which is under any budget, so the test passed against a kernel that resized nothing: green on the commit before the feature. Its rule is upper-bound only now, so the vector has to move, and it fails when the resize is removed. Signed-off-by: arpan <contact@arpanghoshal.com>
…se the kernel Two sections of the spec contradicted each other. §4.2.1a says every observed receipt carries budget_charges and makes summing them how a budget is sized; §8.3 says the resumed receipt is the only receipt an MCP multi round-trip or ACS action ever gets. But the resumed leg reads the ledger, and under observation the ledger is empty by design, so exactly the deployments §8.3 is about contributed nothing to the sum. An independent review found it. Observe mode recomputes the counterfactual; enforce mode still reads the ledger, because there the row is evidence of a spend that happened and a recomputed number would be a claim about it instead. And verify could still report FAIL, which means the kernel is broken, for a budget that was merely small. A vector is left alone when it fits, but a scenario acts more than once: G4 runs eight children on distinct keys and then contends eight more on one, so nine spends land. A band with a floor cannot be shrunk below it, so amount_gte: 200 against a limit of 900 left the vector untouched and G4 reported the kernel broken. The fit is against the room a scenario needs, not one action, everywhere the vector is chosen or accepted. Two mutation survivors are closed with the documents where the guards actually bite. The headroom rule never binds on a band that admits 1, because the first candidate is tiny; T413g gives it a floor. The rule-identity check never binds unless two bands reach the same decision; T413h gives it two, so that resizing across them would grade a rule nobody selected. The re-resolution after a resize now requires the SAME grant rather than any grant that fits. _bind is building a selection that names one grant, and a vector graded against a different grant's budget reports the wrong grant and checks a budget nobody will apply. That subsumes re-checking the grant's shape and constraints, which is removed rather than kept unexercised. Stating both misses also introduced a false one: select records a grant miss for every failed candidate, including candidates a budget declined, so a single-grant document was told no grant's resources: matched about a pattern that matched perfectly. A budget decline no longer records a resource miss. receipt.py and §10.1 both described budget_charges as what the action charged, which is false on an observed receipt. Both say what result tells apart. Signed-off-by: arpan <contact@arpanghoshal.com>
…emonstrate _secure computes charges before calling _in_scope; _observe_secure ran the scope check first. So an action that is both out of scope and unmeasurable was refused budget_unmeasurable by enforce mode and reported out_of_scope by the pilot. Whichever order is right, one of them has to follow the other, and the enforcing one is the one that decides. This is the third instance of the same defect in this milestone, and all three came from the two paths being separate implementations: the approval gate, the reservation, and now the scope check.

Items 5, 6 and 7 of v0.9 "Envelope". Companion docs PR: CTRLRun/ctrlrun-docs#9.
Merge order matters. The
docsjob audits the docs repository'smainand has been red on this repository'smainsince item 3; the docs PR in turn builds against this repository'smain, where G22 does not exist yet. This merges first, then the docs PR goes green, thendocspasses here.Item 5 — consumption, holds and releases (§4)
§4.2's table has nineteen dispositions and the implementation has one rule: released exactly when the effect reaches
FAILED, held in every other state. Five blockers from the item's own review are fixed here.§4.2's table had twelve rows with no test, and the mutation that matters survived all 42. Moving
_release_lockedabove the state check keys the release on the call rather than the state reached, so a refusedfail_effectreleases the hold on anAMBIGUOUSrecord — the manufacturable refund this item exists to stop — and the whole suite stayed green. T425 pins it. The mutation also taught something worth writing down: both SQL stores roll the transition back when the check raises, so the ordering is redundant there, while the in-memory store mutates a dict under a lock and the order is the atomicity. The code says so now.§2.3 and §2.4.1 refusals left no record, and ran after the approval gate. They escaped as a bare
InvalidArgument: noACTION_DENIED, no receipt, nothing in the one record an operator has of a refused action. And running them after the gate asks a human to approve a refund the kernel has already decided to refuse, leaving a granted approval behind for an action nothing can execute — a probe foundAPPROVAL_REQUESTEDwritten for exactly that shape. Both halves fixed; the exception type is unchanged, because neither is a budget running out.A resumed leg reported a number from a context variable. §8.3 makes that receipt the only one an MCP multi round-trip or ACS action ever gets, and
resumenever reset the variable: a gateway that restarted mid-round reported no charges for an action that spent, and one that had run another action since reported that action's spend. It reads the ledger now, by effect key and attempt.consumptions()gains aneffect_keyfilter for that read, recorded in §3.3.3 rather than slipped in.Observe mode charged nothing, which was right, and reported nothing, which was the missing half. It now evaluates §3.3.1's predicate against the ledger and records what would have happened, through
check_charges— the same function all three stores enforce with, so the report and the enforcement cannot drift.§4.2.1 overclaimed and the fix was to make the claim true. It said observe mode is "how an operator sizes a budget before turning it on". It is not: observe mode charges nothing, so a deployment observing everything has an empty ledger and reports that no budget would refuse anything. §4.2.1a states that limit, and observed receipts now carry the counterfactual charge — which a probe found to be an empty tuple, making the sizing path the section described impossible.
A duplicate-charge guard killed §2.2's own motivating shape. Two budgets on one metric over two windows is "the first thing an operator asks for", and a guard refusing any duplicate
(grant_id, metric)pair meant the loader accepted the document, observe mode called it clean,verifycould not grade it, and enforce mode died with no receipt. The guard now refuses only what it is actually for: two charges on one metric with different amounts, which §3.4's key would silently collapse.A budget must not make
ctrlrun verifyreport an internal error. A grant whose budget is smaller than the vector_synthesizepicked refuses the action before the guarantee is reached, and verify reported that as exit 3 on guarantees with nothing to do with budgets. This is the third time this shape has been found —approvals_required: 2did it, an approver role did it — and it gets the same answer: verify sizes its own vector. Where nothing fits a band, the guarantee isN/Awith a reason naming the action and the grant, rather than falling through to a grant miss that blamedresources:on a document whose patterns matched perfectly.examples/authority/payments.yamlkeeps its €500,000 daily budget. Itsamount_lteadmits a €100,000 single refund and its approve band runs to €10,000, so €1,000 a day would make every human-approval path unreachable — the mistake the file's own comment warns about. The widening was the right number; verify crashing on the wrong one was a separate defect.Item 6 — the operator surfaces (§7)
No new command, per §7.1.
ctrlrun inspect --grantreports each budget as consumed, held, and why — the effect holding each part and the state it is in.The third is the deliverable. A budget that refuses while it looks nowhere near its limit is almost always one unresolved effect, and the view prints
ctrlrun resolve <effect-key>with the key already in it: an operator retyping it from the line above is one transcription away from resolving a different effect. T434b drives the whole path, refusal to cleared.ctrlrun effectssays what each effect is holding, so--state ambiguousanswers "what is pinning this grant". It says spent for a committed effect and holds for every other, because §7.2 defines held as the part that has not committed and one word for two numbers would make the two commands disagree.ctrlrun statsreports the ledger row count. The count is produced inctrlrun.reporting, not in the CLI:SPEC-mcp-operator §9.1gives one document one producer, and a key the CLI reported and the operator server did not was two shapes under one schema name. T193 caught exactly that.A ledger row whose effect record is gone is reported held with a null state rather than skipped. §7.3 permits archiving rows the window can no longer reach, and skipping one would under-report
held— the one direction this view may not err in, because it is the direction that hides a hold.Item 7 — release 0.9.0
Version 0.9.0, the
[0.9.0]CHANGELOG section undated until the tag, and a Stricter than 0.8.0 section with what 0.8.0 did.The bump moved four things with it. Both adapters pinned
ctrlrun>=0.5,<0.9, which excludes this kernel; the range becomes<0.10rather than opening, because the adapter contract is not frozen until v1.0. Four files state it per adapter and the packaging tests check all four.CITATION.cffcarries the version too.Two CHANGELOG claims had gone stale as later items landed:
DIMENSIONSwas written as seven when item 1 addedtasks, and item 3 made it eight; the authority badge line still read 20/20, from before G22 and G23 existed.§13 is written, one subsection per item from the CHANGELOG lines each left when it landed. §13.0 is the milestone's own entry and the one worth reading: every design claim this spec made about its own code had to be probed, and the ones that were not were wrong about a third of the time. Across three review rounds every citation was accurate and roughly three design claims per round were false.
