Operator-reported bug: on 'proceed with the rest' the agent re-proposed the
plan, duplicating it in the sidebar. Root cause was a three-bug chain, not
one bug:
1. Trigger — model empty-response on 'proceed' (approval vocabulary didn't
list 'proceed', so the agent wasn't sure it was approved and no-op'd).
2. Amplifier — chatWith emitted 'error' without 'done' on empty response
(agent.go:370). The frontend's onComplete saw !receivedDone and
misclassified the model failure as a network disconnect, calling
handleDisconnect -> resumeSession.
3. Divergence — the reconnect note was generic ('report your state'), so
the agent re-proposed + re-executed instead of advancing the plan.
Fixes (shipped, e2e-validated against the live agent on oikos-nomos-1):
- A.2: proposePlan refuses re-proposal once a step has started (returns
errPlanInFlight). Drops the append-mode safety net (commit 5384499) that
was the direct source of the sidebar duplication. The agent must advance
with update_plan_step + run; the tool result directs it.
- A.1: proposePlan sets the 'generation' column on INSERT (migration 020
added the column + frontend grouping, but the INSERT never wired it).
- A.3: propose_plan tool description restated as a crisp contract (ONCE,
STOP and wait, REFUSES once a step started, advance with update_plan_step).
- F.3: approval vocabulary expanded to approved/yes/go/proceed/continue/ok/
go ahead; propose_plan result string tightened to an imperative.
- B.1: chatWith emits 'done' after 'error' on every terminal path via a new
emitError helper. The frontend now treats model errors as ended (not
disconnected), so no auto-reconnect -> resumeSession fires.
- B.2: reconnect/resume note carries the operator's last message + an
explicit 'advance the plan, do NOT call propose_plan again' directive when
a plan is in flight. Wired into all 4 resume entry points (reconnect,
/resume, idle-sweep, question-answer) via enrichResumeNote.
- B.3: resumeSession escalates the recovery note across its 3 attempts (final
retry: 'pick the lowest-pending step, mark it running, call run — do that
now') instead of 3 identical notes -> 3 identical empties.
Verification: TestProposePlan_RefuseInFlight replaces TestProposePlan_
AppendVsReplace. e2e conversations against the rebuilt container:
conv2 ('proceed with the rest') -> 0 propose_plan calls, plan stayed at
3 steps (was 6+ before), update_plan_step x5 + run x2 + complete_task.
conv3 (full plan, 'go ahead') -> apt-get update on lxc:dns auto-ran under
the plan window, update_entity_attributes writeback, clean complete_task.
nomos logs show zero reconnect/resume entries for the plan-proposing
sessions (the three-bug chain is closed).
Remaining (not in this commit): D.1 refuse complete_task without writeback
(next blocker), C.1/C.2, F.1/F.2 SOUL.md consolidation, B.4-B.6, E.1/E.2.

Also: re-audit 2026-07-10-general-gated-execution.md — request_execution enum
retirement (60effcb) closes item 9; only auto-act revival (item 10) remains.
Version 0.4.1 -> 0.5.0 (minor: new structural behavior, not a bugfix).
