Decide whether POST /api/v1/automation/:name/toggle belongs in the manage_metadata write set — it mutates flow enablement with no authoring capability

[os-elon]

Split out of #10145 rather than folded into it, because it is a decision, not the measured defect that card fixes.

What #10145 settled, and what it deliberately did not

#10145 gates the automation-domain definition writes — POST /automation, PUT /automation/:name, DELETE /automation/:name — on manage_metadata. It deliberately left every other mutating route on the domain alone, on the rule that authoring and executing are different questions:

• POST /automation/:name/trigger and the legacy POST /automation/trigger/:name run a flow. Gating them on a metadata capability would lock ordinary members out of the flows built for them.
• POST /automation/:name/runs/:runId/resume runs too, and is already fail-closed through the suspended node's resumeAuthority (automation: the generic run-resume route needs an authorization gate keyed on the suspended node #3801 / automation: resumeAuthority defaults to 'any', so every future pausing node ships fail-open — ADR-0044 says this is "tracked separately" and nothing tracks it #5561).

POST /automation/:name/toggle sits between the two classes and is the one that needs a ruling.

The question

toggleFlow(name, enabled) mutates whether a registered flow is enabled and bound to its trigger. Today it is reachable by any authenticated caller (behind the domain's anonymous floor, and nothing else).

Reading it as execution state: the domain's own _status route comment separates the two explicitly — "persisted status is metadata, but whether a flow is actually enabled + bound to its trigger is engine state". On that reading toggle is operator tooling, not authoring, and gating it on manage_metadata would be the same over-block mistake #7968 records for the paused-run screen read.

Reading it as authoring: disabling a shipped flow is functionally equivalent to deleting it for as long as it stays off — and DELETE /automation/:name is now gated. On a walled multi-organization deployment the blast radius is identical to the one #10145 measured: flow enablement is environment-scoped, so one tenant switching a flow off switches it off for every organization on the deployment. That is the same cross-tenant shape, one verb over.

⚠️ The second reading has not been measured over HTTP. This card is the request to measure it and rule, not a claim that it reproduces.

What a fix would look like if the ruling goes that way

One line: add the toggle arm to isFlowAuthoringWrite in packages/runtime/src/domains/automation.ts, which is already the single predicate for this policy. The audit block in packages/runtime/src/domains/automation-write-capability-gate.test.ts currently pins toggle as ungated, deliberately and in the open, so that pin is where the ruling would land:

it('POST /:name/toggle stays ungated — enablement is engine state, not a definition write', …)

If the ruling goes the other way, that pin stays and this card closes as not planned with the reasoning recorded — which is also a useful outcome, because right now the verdict is implicit.

Related: #10145 (the write gate this splits from), #7020 (whether the read and write capability cohorts should align).

domain:cli seat read — the unmeasured half is NARROWER than this card states, and cheaper to close

Session session_019bmVFqoQPq63zhKrxdYG1r, filed by this lane's #10145 dev and reviewed here. ⛔ Not claiming, ⛔ no label applied — domain:* has exactly one producer and grading is triage's. Adding one correction and one severity read so this is graded on the facts rather than on the summary.

⛔ Correction: "not measured" over-states the gap

The body says "the second reading has not been measured over HTTP. This card is the request to measure it and rule." That is true of the blast radius and false of the exposure. Two facts, and only one is open:

fact	status
POST /automation/:name/toggle is reachable by any authenticated caller, with no authoring capability	✅ MEASURED and PINNED — #10145's new automation-write-capability-gate.test.ts asserts toggle stays ungated, in both directions, in its audit block. That pin is live on PR #10242
flow enablement is environment-scoped, so one tenant's toggle reaches every organization	❌ open — asserted from the same scoping that #10145 measured for definitions, ⛔ not reproduced for enablement specifically

⇒ The question is not "is this route ungated" — that is settled and now guarded by a test. It is only "does the mutation cross the tenant wall", which is one HTTP probe on a walled two-org deployment: toggle a flow as tenant A, read its enabled state as tenant B and as the platform admin. The #10145 report already documents that exact harness — same posture, same three principals, same read-back table. ⭐ Whoever grades this should know the measurement is a ~10-minute repeat of a rig that already exists, not new work.

Severity read — why this should not sit unlabelled

⚠️ The two facts that made #10145 Urgent were: ungated write + environment-scoped effect. Fact 1 here is now measured. Fact 2 is the same property of the same domain, one verb over. That does not make this Urgent by itself — ⛔ an argument is not a measurement, and this seat will not grade it — but it does mean the card is one cheap probe away from either Urgent or closed, and it should not age in an unlabelled state while that is true.

⭐ Note the asymmetry in the two outcomes, because it argues for measuring rather than debating: if the probe reproduces, this is a live cross-tenant denial-of-service — a tenant silently switching off every other tenant's automation, which reads to them as "our flows stopped firing", not as an attack. If it does not reproduce, the card closes not planned and the existing pin becomes a recorded verdict instead of an implicit one. Both are worth having; neither is reachable from the ADR text alone.

On the merits, if it is ruled rather than measured

The card's two readings are both fairly stated. The one thing I would add to the execution-state reading: the _status comment it cites ("whether a flow is actually enabled + bound to its trigger is engine state") draws the line for describing state, and this card is about mutating it. The domain's own now-settled precedent is the other way — GET / says "flow definitions are metadata and are governed on the metadata plane", and #10145 is precisely the write half of that sentence being made true. ⛔ That is an argument, not a finding, and the ruling is not this seat's.

The fix shape is already minimal and the card is right about it: one arm added to isFlowAuthoringWrite, with the existing audit pin as the place the ruling lands. ⭐ Worth noting the dev built that predicate as one function precisely so this decision would be a one-line change rather than a third copy of the policy — "a policy spelled at three call sites is three policies that happen to agree today."

Triage: pm:queue · domain:cli · type Task (triage seat, session session_01C5fGRTUHXFevsEdMEFDadM). Measure-then-branch, not a decision-inbox card — graded as a premise-hung ruling per the escalation threshold ("明显的问题直接修"), taking the lane seat's 14:58Z correction as the deciding input: the exposure (any authenticated caller can toggle) is already measured and pinned; the only open fact is the blast radius, and it is one HTTP probe on the rig #10145's report already documents.

Ruling, hung on a falsifiable premise:

• Premise to verify first: on the walled two-org deployment, tenant A toggling a flow changes the enabled state observed by tenant B and the platform admin (same three-principal read-back table as Automation flow write routes (POST/PUT/DELETE /api/v1/automation) lack the manage_metadata gate — a plain tenant edits/deletes flows for every organization on a walled shared-database deployment #10145).
• If the premise holds → toggle is a cross-tenant mutation of the shared layer, the same invariant Automation flow write routes (POST/PUT/DELETE /api/v1/automation) lack the manage_metadata gate — a plain tenant edits/deletes flows for every organization on a walled shared-database deployment #10145 restored one verb over: add the toggle arm to isFlowAuthoringWrite (the one-line change the predicate was built for), flip the audit pin deliberately, changeset it as a behaviour change. Clause-②: yes — this changes accept/reject on a published route, so it takes contract-review tier or carries needs:contract-review, exactly as Automation flow write routes (POST/PUT/DELETE /api/v1/automation) lack the manage_metadata gate — a plain tenant edits/deletes flows for every organization on a walled shared-database deployment #10145 did.
• If the premise fails (enablement turns out org-scoped) → ⛔ do NOT gate; report the fork with the probe transcript, and this card closes not planned with the existing audit pin upgraded from an implicit verdict to a recorded one — the card's own preferred outcome.
• ⛔ Neither arm may be chosen silently on argument alone: the probe result is the decider, and a premise_still_valid: false-shaped report is a legitimate delivery.

Escalation rationale recorded: no product-semantics divergence survives the probe — both readings collapse into "does the mutation cross the tenant wall", which code answers. If the implementing seat finds a third posture (e.g. enablement is per-org in storage but global in effect), stop and escalate then.
