Part of epic #1515. Brief: docs/plans/2026-10-05_s2b-single-use-approvals.md (lead decision 63).

In S2 round 2, one approved gated decision authorizes the same action any number of times (Darkwing probe P3). authorize must record consumption, and a second use refuses with decision-consumed.

Owner: rocko. Reviewer: darkwing. Gate: sage.

Row 43, S2b, round 1: request changes (Darkwing)

Candidate candidate-manifest.sha256 1b4b2f20…, three files under
packages/bus/. Full record:
agents/darkwing/work/slice1-s2b-review/review-r1.md.

The patch applies at 65d78d12 and the manifest checks 3/3. Tests pass
48/48 on Node 26 and on Node 24. Rocko's S1 contract script passes, and
the within-role route_to assertion is in. Six of seven mutants are
killed; the survivor is the R2 fix, which no test covers yet.

The authorize change holds. The check and the event share one
BEGIN IMMEDIATE transaction, and the writer lock allows one Store
per data root, so callers serialize. The decision.raise exclusion
can't be used to skip the check, because no agent path writes that
operation for an existing decision. A gated decision stays consumed after
policy makes its action cross-role. The README's decision 62 note claims
nothing the decision doesn't.

Required:

  • R1: the message.send and role.revoke verbs use gated decisions
    without consuming them. A gated message.send approval sends any
    number of times, and authorize grants it afterwards. Put the check
    and event in one helper that authorize and both verbs call, and test
    each verb.
  • R2: a decision raised cross-role authorizes without limit once policy
    makes the action gated, because the check keys only on the recorded
    class. Check consumption when either class is gated, and test it.

For Sage, two rulings, either of which settles R2:

  1. Cross-role reuse matters. One cto approval of a coder's scope change
    on a task authorizes every later scope change on it in that run. I
    recommend every decision-backed authorization be single-use.
  2. Pre-existing from S2: once policy makes an action gated, an
    arbiter's earlier approval still authorizes it without Jason. I
    recommend refusing when the decision's recorded class differs from
    the current class.

Row 43, S2b, round 2: approve (Darkwing)

Candidate candidate-manifest.sha256 a89d64ca…, three files under
packages/bus/. Full record:
agents/darkwing/work/slice1-s2b-review/review-r2.md.

The patch applies at 57738083 and the manifest checks 3/3. Tests pass
55/55 on Node 26 and on Node 24, and Rocko's S1 contract script passes.

Lead decision 64 and round 1's items are in:

  • R1: authorize, message.send and role.revoke share
    #consumeAuthority, each inside its own transaction. A second send or
    revoke refuses with decision-consumed, and so does authorize after
    either verb.
  • Ruling 1: every decision is consumed once, cross-role included.
  • Ruling 2 and R2: a class mismatch refuses with decision-mismatch.
    Rocko tests all six directions, and my round 1 probe C now refuses.
  • A within-role sender that names a decision gets every check.

Nine of ten mutants are killed. The survivor removes authorize's
transaction, and with one synchronous writer it's equivalent today.

Not blocking: message.send now writes an action.allowed event for
every agent message, which shows up in the recipient role's trail. The
README's "within-role actions remain unchanged" is true for authorize
but not for that verb. S4 should expect these events.

Landed as 4afab552 (row 43, queue rev 147, 6b753ff7). Darkwing approved round 2 in comment 26769. Integration gate in a worktree on bba75b4a: every package green on Node 26, bus 55/55 on Node 24, every scripts/test-*.sh green. Node 24 failures in conversation, ledger, queue, seat and webui match the unpatched base exactly. The container has an overlayfs /tmp and no jsonschema, so they are environmental.

Follow-ups from Darkwing, not blocking: the README line "Within-role actions without a decision remain unchanged" holds for authorize but not message.send, which now writes action.allowed for every agent message. Rocko fixes the wording on the next README change, and S4 accounts for those events in the trail.

Closing. -- Sage
