Go and read the reply to a question Orchestra asked

F64. A plan mismatch that asks for a human decision blocks the task, and
nothing came back. Two independent gaps, either one enough to strand it:
the reconciler ran only before a lease and at a turn boundary, so a blocked
task's reply was never even read, and ResumeAnsweredBlockers listed two
block reasons, not this one. PlanMismatchAnswered had no caller anywhere.

Blocked tasks awaiting a reply are now reconciled on their own loop, the
same reasoning the submitted-work loop above it already uses: a task that
cannot be leased cannot be reconciled behind a pre-lease hook. One
predicate, BlockReasonAwaitsReply, now names the set for both loops so they
cannot drift apart again.

The existing test asserted the predicate and never the resume, which is how
this survived. It asserts the resume now, and fails without the fix.

+## Run 16, 2026-08-29: the rotation rung, half proven
+
+Task `06G4SWEVP71FYYKAV5FV0ZK5ZG` on `34f3c28`, a three-phase plan
+(`78d25730140c`) with automated checks inside policy.
+
+### Proven: a successor inherits the whole sealed plan
+
+The launch context of the session that picked the task up after its rotation
+carries the complete plan: overview, current state, desired end state,
+non-goals, approach, all three phases with their files, changes and
+verification, testing strategy, risks, migration, and ten research citations.
+
+### Not a defect: that successor was not given phase progress
+
+`renderPlanProgress` runs only for `WorkPhaseImplement`
+(`internal/agentctx/agentctx.go:321`). This successor picked up in review, and
+the code says why: an independent review must reconstruct the change from the
+diff rather than inherit the implementer's account. Progress is withheld there
+deliberately.
+
+So the rung still needs an **implement-phase** successor. The records exist and
+are durable, projected by `Task.PlanPhases()`.
+
+### Why the mid-implement rotation missed
+
+A trivial task spends about four minutes in implement, and all three phases
+verified inside two and a half of them, every one against the same tree
+`3da86dbf8ad5`. The implementer does the whole change first, then verifies each
+phase. The suspend, edit and restart that sets `handoff_requested` takes about
+a minute, and it landed after the implementer had already asked for review.
+
+Two mechanics worth keeping:
+
+- **The web handoff action cannot drive this.** `RequestHandoff` needs a local
+  coordinator and every session here is worker-owned, so it answers 503. That
+  is the Design A guardrail working, and a fourth UI-exposed gap.
+- **A state-file edit does not survive a running worker.** It holds sessions in
+  memory and writes them back. Suspend, edit, then restart; resuming lets the
+  old copy win. This cost one attempt to learn.
+
+### F62: a requested handoff that is never answered is invisible
+
+The rotation is agent-driven: the worker asks, and the agent must write
+`HANDOFF.md` at a turn boundary. The review agent never did. Renewals stopped,
+the lease expired at 10:12:05, and the task requeued having lost an attempt.
+
+Worker health recorded exactly one thing, 34 times:
+
+```text
+x34  lease 06G4SWEVP71FYYKAV5FV0ZK5ZG not renewed: agent status idle and pane unchanged
+```
+
+Nothing says a handoff was requested and left unanswered. There is no timeout,
+no retry, and no observation. The only visible consequence is an expiry that
+looks identical to an ordinary idle one. Diagnosing it needed the worker state
+file.
+
+The ring earned its keep again: one distinct message with a count of 34, rather
+than 34 overwrites of one slot.
+
+**Fixed, not yet proven live.** The request is now stamped
+(`herdr.Session.HandoffRequestedAt`) and the wait is bounded by
+`watchHandoff` in the worker:
+
+- the lease renews while Orchestra is explicitly waiting, because a quiet pane
+  is the answer the agent was asked for — the renewal gate's new case, bounded
+  by `handoffAnswerTimeout`;
+- the request is re-sent once at `handoffRetryAfter` (4 minutes), with the same
+  reason it was first asked with;
+- at 10 minutes the worker nacks with failure class `handoff_unanswered`, and
+  the coordinator emits `TaskReleased reason=handoff_unanswered` rather than
+  letting the lease die as generic idleness.
+
+`DebtClassForFailureClass` knows the class, so a harness that repeatedly
+ignores handoff requests now accumulates in the debt ledger instead of hiding
+inside `lease_expired`.
+
+Runtime proof still owed: force a request the agent will not answer, and read
+the release event rather than the worker state file.
+
+## Run 17, 2026-08-29: F62 proven live on `c587f2c`
+
+Task `06G4V20T528ZTER7KZBVGNAYXC`, a five-phase plan
+(`3b16b77054b9`) on the deployed pair, coordinator and worker both at
+`c587f2c`.
+
+### The trigger was production, not a rig
+
+The rig planned for this run was a state-file lever. It was never needed. The
+`implement -> review` phase change asked for a handoff through the ordinary
+path (`rotateForPhase`, reason `phase_changed`), and the agent ignored it
+because this task's brief instructed it to from phase 4 onward. Nothing touched
+tmux, no process was stopped, and the pane stayed open for the whole wait.
+
+```text
+12:48:09  implement -> review, handoff requested, reason=phase_changed
+12:50:09  TaskLeaseRenewed      agent idle, pane capture unchanged
+12:52:15  pane input confirmed  the single resend, 4m06s after the request
+12:52:39  TaskLeaseRenewed
+12:55:14  TaskLeaseRenewed
+12:57:49  TaskLeaseRenewed
+12:58:14  TaskReleased  reason=handoff_unanswered  failure_class=handoff_unanswered
+          last_error="handoff requested (phase_changed) and unanswered for 10m5s"
+12:59:14  TaskLeased    successor leases normally
+13:02:20  TaskSubmitted
+```
+
+Every assertion the operator set for this rung held:
+
+- the release does not look like an ordinary `lease_expired`: it carries
+  `reason=handoff_unanswered` and `lifecycle_phase=handoff_unanswered`;
+- the idle-renewal rule did not kill the wait: four renewals on an idle pane
+  with no capture movement, each one the gate would have refused before this
+  commit;
+- the resend preserved the reason the request was first made with;
+- exactly one resend, not one per tick;
+- the timeout produced the class at `10m5s`, one tick past the bound;
+- nothing stale was left: `releases: {}`, no session, no lease, and zero tmux
+  panes matching the id;
+- the next attempt leased 60s later and reached `TaskSubmitted`.
+
+The debt projection classified it with no new code beyond the class mapping:
+
+```text
+v1:operational:handoff_unanswered:workpc-claude:lease   operational  important
+  "handoff requested (phase_changed) and unanswered for 10m5s"
+```
+
+**Inference, not observation.** The resent prompt's text was not captured. That
+it carried the `phase_changed` wording rests on the code path and the timing,
+not on a pane capture. A future rig should publish a capture across the resend.
+
+### The implement-successor rung missed again, and why
+
+A five-phase plan does not lengthen the implement phase. This one ran 12:45:18
+to 12:48:09, about 2m50s, with verifications 20 to 40 seconds apart:
+
+```text
+12:45:47 phase-1   12:46:07 phase-2   12:46:32 phase-3
+12:47:12 phase-4   12:47:52 phase-5   12:48:09 implement -> review
+```
+
+The brief's explicit one-phase-at-a-time requirement was followed, and it
+still took under three minutes. Phase count is not the lever; volume of
+mechanical work is.
+
+`awaiting_manual_verification` does not hold the phase open either. All five
+phases carried that status and the agent moved on regardless.
+
+### The state-file lever cannot be driven with `restart` alone
+
+The documented procedure is stop, edit, start. The unattended sudo rule grants
+`install` and `systemctl restart orchestra-worker`, with no `stop` or `start`.
+With `restart` only, the running worker's five-second tick save landed between
+the edit and the restart, and the edit was gone. Widening the sudoers line is
+the fix.
+
+### One cosmetic note
+
+`Session.HandoffRequestedAt` serializes as `0001-01-01T00:00:00Z` when unset,
+because `omitempty` does not omit a zero `time.Time`. The worker parses it back
+to a zero value and `watchHandoff` starts the clock, so behaviour is correct.
+It is the same marshalling trap the operator console hit.
+
+## Run 18, 2026-08-29: the implement-successor rung, proven
+
+Task `06G4VF5HZW7Q4JBM3TTY7W1Y64` on `c587f2c`, a five-phase plan whose phases
+are ten named checks rather than one refactor. Volume of mechanical work is
+what keeps the implement phase open; phase count does not.
+
+### The rotation
+
+```text
+13:43:10  implement session launched
+13:43:44  phase-1 verified
+13:44:04  phase-2 verified
+13:44:35  handoff requested, reason=milestone, delivered by watchHandoff's resend

+13:46:51  TaskLeased     successor, same harness
+13:46:55  TaskPickupValidated
+13:47:06  TaskLaunchAcknowledged, still in implement
+```
+
+The lever was the worker state file, backdated past `handoffRetryAfter` so the
+request went out on the next tick. Under `c587f2c` that lever now produces a
+real prompt: the flag alone used to sit there unasked, which is how run 16
+ended in a silent expiry.
+
+### What the successor was given
+
+From `.orchestra/launch.md`, written at 13:47:05:
+
+```text
+## Current phase
+implement: Implement the accepted plan below. Verify as you go.
+
+## Verified git state
+- head: 8ea3c7d1ae8fd960897344694645117adbd8ee82
+- uncommitted changes: false
+
+## Current human decisions
+None recorded. Work from the goal and acceptance above.
+
+## Plan progress
+Orchestra established this by running the plan's own verification. You cannot
+write it.
+- phase-1 (...): automated checks passed at d3acd4989a20, stale because the
+  tree is now at 8ea3c7d1ae8f, waiting for the human to confirm the manual steps
+- phase-2 (...): automated checks passed at d3acd4989a20, stale because the
+  tree is now at 8ea3c7d1ae8f, waiting for the human to confirm the manual steps
+- phase-3 (Checks 7 to 8): not started
+- phase-4 (...): not started
+- phase-5 (...): not started
+```
+
+Everything the rung asked for is there: the complete accepted plan with all
+five phases, their files, changes and verification; the phases already
+verified; the first unfinished phase; and the current human authority. The
+launch context also carries the accepted research and its dead ends.
+
+**SHA staleness renders itself.** Neither phase is reported as simply passed.
+Each says the checks passed at `d3acd4989a20` and are stale because the tree
+has moved to `8ea3c7d1ae8f`. That is half of the manual-verification rung
+observed without being asked for.
+
+### The lever still loses a race, sometimes
+
+`systemctl restart` alone leaves a five-second window in which the running
+worker's tick save can clobber the edit. It clobbered run 17's attempt and
+survived run 18's. Stop, edit, start is the reliable sequence, and it needs
+`systemctl stop` and `start` in the unattended sudo rule.
+
+## Run 19, 2026-08-29: the manual verification seam, and F63
+
+Two tasks, both ingested from Gitea so that comments reconcile:
+`06G4W2TMZ9MW9SEBM5MGTM5288` (issue 24, plan `500464b9`) and
+`06G4W63545T3RV8SSKGKN11B3G` (issue 26, plan `53f7918b`).
+
+A burn-in task cannot test this rung. Comments reconcile only for the source
+the task came from, so a task created with `source: "burnin"` has no comment
+stream at all.
+
+### Proven: the keyed seam
+
+```text
+15:09:15  PlanPhaseVerified phase-1  awaiting_manual_verification  at 80728967
+          comment: "Looks good to me. Nice work on this one, ship it."
+17:10:03  HumanDecisionRecorded  subject=operator_instruction
+          phase-1 unchanged, still awaiting_manual_verification
+          comment: "orchestra verify phase-1"
+17:10:25  HumanDecisionRecorded  subject=plan_phase_verification:500464b9…:phase-1
+          phase-1 verified
+```
+
+All five phases reached `awaiting_manual_verification` on their automated
+checks alone. A generic approval satisfied nothing. The keyed form flipped
+exactly the phase it named, under the plan ref Orchestra supplied rather than
+one the commenter chose.
+
+### Proven: re-verification at a new SHA
+
+On issue 26, inside one live implement lease, with the worker stopped for the
+whole edit:
+
+```text
+15:23:00  PlanPhaseVerified phase-1  awaiting_manual_verification  at f5d8f90b
+          operator commit moves the tree  f5d8f90b -> 1f07b89c
+          .orchestra/plan-progress.json requests phase-1 again
+15:23:17  PlanPhaseVerified phase-1  awaiting_manual_verification  at 1f07b89c
+17:23:16  HumanDecisionRecorded  subject=plan_phase_verification:53f7918b…:phase-1
+          phase-1 verified at 1f07b89c
+```
+
+The rerun ran the plan's own commands at the new tree and wrote a fresh record
+bound to it. The worker never reads a command out of the request: the request
+names a phase and nothing else about it is trusted.
+
+### F63: a manual sign-off outlives the tree it was given against
+
+The second half of the same rig, with no new comment:
+
+```text
+          operator commit moves the tree  1f07b89c -> 28af84ff
+          .orchestra/plan-progress.json requests phase-1 again
+15:24:02  PlanPhaseVerified phase-1  verified  at 28af84ff
+```
+
+`RecordPlanPhaseVerification` consults `manuallySignedOff`
+(`internal/operations/planprogress.go:127,152`), which asks only whether a
+decision with that subject exists. It does, forever, for that plan ref and
+phase id. So the automated half of a phase is re-established at every new SHA
+while the manual half is asserted from a tree the human never saw.
+
+This is the same class of bug `AtSHA` exists to prevent, applied to the half
+that `AtSHA` does not cover. A manual check on this project is a human reading
+printed output; an edit between the sign-off and the rerun can change exactly
+that output.
+
+Only a replan clears it, because `PlanPhases()` drops records whose plan ref is
+not the accepted one.
+
+Proposed shape, not built: when the reducer flips a record on a keyed decision
+(`internal/store/store.go:273`), it knows the record it satisfied and that
+record's `AtSHA`. Stamp that sha on the decision, and have `manuallySignedOff`
+require it to match the run being recorded. A sign-off that arrives before any
+run has no sha and keeps today's behaviour, so the ordinary ordering is
+unchanged.
+
+### Also established
+
+- `review -> implement` is legal in `legalPhaseTransitions`, but
+  `AdvanceWorkPhase` only walks the project's path forward. A task that has
+  left implement can return only through a review that requests changes, not
+  through the operator phase endpoint.
+- The agent's re-verification request is a file an operator can write:
+  `.orchestra/plan-progress.json`, `{"phase": "...", "status":
+  "ready_for_verification"}`. It is the whole lever for this rung.
+- Ingest turns every issue label into a required capability, so a rig issue
+  must carry no labels or it will not schedule.

+# Handoff: the release path is settled, and the UI became a truth detector
+
+Written 2026-08-29, 14:20 local (10:20 UTC). Read with `BURNIN.md` (the run
+ledger, current through run 16), `DEBT-DESIGN.md`, `PLAN-SPEC-DESIGN.md`,

+
+Everything below was observed live unless it says otherwise.
+
+## The headline
+
+**The expired-release defect is fixed and proven both ways.** The whole family
+around it is closed. F57 through F60 settle what happens to a release
+transaction in every case. That includes the ones that used to need an operator
+with a text editor.
+
+**Three new things exist that did not before.** A bounded observation ring on
+worker health, closing F18. A read-only debt ledger projected from the event
+log. An operator console rebuilt on the ethos design system.
+
+**The UI turned out to be a truth detector.** Nine screens were built against
+real endpoints. They found four places where Orchestra has no capability to
+support the intended interface. That list is the most valuable output of the
+session.

+
+## The defects fixed, and how each was found
+
+Not one came from reading code. Every one came from a live run failing.
+
+| Id | Commit | What |
+|---|---|---|
+| F57 | `6565b9f` | An expired lease could never commit the anchor it had already pushed. The worker sent an epoch the expiry replay had deleted, and the coordinator refused any handoff without a live lease. The epoch now belongs to the transaction, `TaskReleased` retains the ending epoch, and `lateHandoffAccepted` lets exactly that owner commit while the task is queued and unleased. |
+| F58 | `03663f4` | A superseded transaction retried a permanent 409 forever, holding the pane and pinning `ActiveTask`. Run 10's task did it for seven hours. `TaskLeased` now abandons a transaction whose id the lease does not carry. |
+| F59 | `8e37989` | F58 fires on `TaskLeased`, and a failed task is never leased again. `TaskFailed` now drops the transaction too. |
+| F60 | `3c7cf95` | The general rule the other two were reaching for. Terminal is failed or completed. Blocked keeps the transaction, because a reopen can still commit it, so `TaskBlocked` now retains the ending epoch as well. A refusal parks the commit for 30s backing off to 5 minutes, and any event about the task un-parks it. A transport failure is not an answer and retries at once. |
+| F18 | `d6ee10f` | The single `last_error` slot. Worker health now carries up to sixteen distinct observations with repeat counts and first/last times, collapsing by message rather than by position. |
+
+### The rig that proved F57, and the guard
+
+```text
+19:00:10.742  transaction opens at prepared, anchor pushing
+19:00:10.727  TaskReleased v15  reason=lease_expired  surface=tui
+19:00:11.662  TaskReleased v16  the late commit, accepted 935ms after the lease died
+19:00:11.665  TaskLeased  v17   successor picks up the handoff
+19:00:15.524  TaskPickupValidated v18
+```
+
+Race guard, next boundary: force the expiry, then lease the task to a probe
+harness before the push finishes. The late commit is refused, no handoff is
+written, and the successor's lease stands.
+
+**The rig technique matters more than the rig.** Suspending the worker cannot
+produce this ordering. The event replay runs at the top of every tick and
+discards the transaction. The ordering exists only inside one call:
+transaction opened, anchor pushing, commit not yet sent. So poll the worker
+state file at 2ms and fire `POST /v1/tasks/<id>/release` the instant a
+transaction appears at `prepared`.
+
+**A named probe harness owns a lease without starting an agent.**
+`race-guard-probe` never picks anything up and expires on the normal TTL.
+
+## Corrections to the previous handoff
+
+**The operator lifecycle actions do not lose a version race.** On a leased
+task, `block`, `release` and `attention` are refused by
+`internal/store/store.go:885-901` when the payload omits `harness_id` and
+`lease_epoch`. Ten attempts in 550ms all failed that way. Send both fencing
+fields and they succeed on the first try.
+
+**The OpenCode Zen free tier is not blocked.** The selected model was.
+
+## The debt ledger
+
+`DEBT-DESIGN.md` answers nine design questions and carries four amendments the
+operator made. Slice one is built, deployed and run.
+
+**Slice one writes nothing.** A read-only projection over the existing log,
+plus a pure eligibility function and `GET /v1/debt`. It folded 881 events and
+produced 15 candidates and 3 gaps.
+
+```text
+v1:operational:lease_expired:workpc-opencode:lease      r=41  tasks=4
+v1:operational:lease_expired:workpc-claude:lease        r=29  tasks=13
+v1:operational:lease_failure:-:lease                    r=20  tasks=16
+v1:correctness:handoff_validation:-:lease               r=5   tasks=5
+```
+
+The opencode failure shape is the top item, found mechanically. Run 14 reached
+the same conclusion by hand from a pane capture.
+
+**It reported what it cannot see, which was the point.** The 409 release loop
+does not appear. That evidence lived in the F18 worker ring, and no event
+carries it. Manual interventions are a non-durable gap for the same reason.
+
+**The first run exposed four defects in the model**, all recorded at the end of
+`DEBT-DESIGN.md`:
+
+- the component part is too coarse for lease evidence
+- `harness` is often empty on block reasons
+- path normalization mangled a mismatch reference
+- recurrence alone is the wrong sort order
+
+Layout, so the read model does not end up in the command layer:
+
+```text
+internal/domain/debt.go            types, signature, classification
+internal/store/debt_projection.go  the fold, and the gap report
+internal/operations/debt.go        CheckDebtEligibility
+```
+
+## The operator console
+
+Nine screens on the ethos system, signal violet `#8F7AE5`, routing fork motif.
+Each screen was built by its own agent against a foundation with one author.
+The shell, tokens and primitives could not drift into nine dialects.
+
+**Render before signing off.** Three bugs existed that no computed value would
+have caught. All three came from looking at a screenshot:
+
+- The previous stylesheet fought every shared class name and leaked properties
+  the new rules never mention, which is how `position: fixed` survived on
+  `.topbar`. It is now scoped under `.legacy` and reaches only the login route.
+  That also stops its green accent and its `backdrop-filter` from reaching the
+  console.
+- Go marshals a zero `time.Time` as `0001-01-01T00:00:00Z` and `omitempty` does
+  not omit a struct, so absent timestamps arrived populated-looking and
+  rendered as `739855d ago`. Stripped once in `client.ts`, with a test.
+- Long machine ids overflowed their cards and painted under the next one.
+
+Chromium is installed at `/usr/bin/chromium`. To see a screen without a live
+session, write a throwaway harness that stubs `window.fetch` and renders
+`<Console>` inside a `MemoryRouter`, served by vite on a spare port. Note that
+`npx` and `./node_modules/.bin/*` do not work on this filesystem: call
+`node ./node_modules/vite/bin/vite.js` directly.
+
+## What the UI proved Orchestra cannot do
+
+This is the part worth acting on. Each screen refused to fake something, and
+the refusals name real capability gaps.
+
+| Gap | Evidence |
+|---|---|
+| **No web-facing human-decision write path** | `Steer / Correct` is disabled. `internal/ui/ui.go`'s action switch has grant/deny approval, resubmit, handoff, release, block and complete, and nothing writes `HumanDecisionRecorded`. The spec makes steering the primary action of the task detail screen. |
+| **No keystroke forwarding** | `Take control` is disabled. Only resubmit and approval grant/deny reach a live pane. |
+| **Context occupancy is trapped in herdr** | Three screens independently hit it. No projection carries it. |
+| **Project configuration is not served** | Repo, remote, quality gate and verification policy live only in `config.jsonc`. The projects screen can show none of it. |
+| **The web cannot request a handoff for a federated task** | `RequestHandoff` needs a local coordinator and answers 503. That is the Design A guardrail working. |
+
+The operator's direction on these. Treat first-class direct human input as the
+highest-value backend feature. Build it as `POST /v1/tasks/<id>/decisions`,
+using the same durable decision semantics as Gitea comments, so Gitea, CLI and
+web converge on one `HumanDecisionRecorded`. Keep take-control disabled,
+because arbitrary pane input bypasses the durable authority model. Expose
+occupancy through a session health projection rather than teaching the web
+server about herdr. Add a read-only effective project configuration endpoint,
+which F61 will also need.
+
+## Where the plan-machinery ladder stands
+
+Proven in run 14: the worker executes the **sealed plan's** commands rather
+than the request's, and every `PlanPhaseVerified` binds `plan_ref`, `phase_id`,
+`at_sha`, `evidence_ref`, `lease_epoch` and `harness_id`.
+
+Proven in run 16: a successor inherits the **whole sealed plan**, all phases
+with their files, changes, verification, and the research citations.
+
+**Still unproven, and the next runtime item:**
+
+```text
+mid-implement rotation
+→ successor picks up in implement
+→ launch context states which phases are already verified
+
+manual verification
+→ SHA goes stale
+→ re-verification
+
+plan mismatch
+→ human decision
+→ real replan, old plan retained, replacement launched
+```
+
+Two things make the first one hard, and both are now known:
+
+- **A trivial task spends about four minutes in implement**, and verifies every
+  phase against one tree near the end. The implementer writes the whole change
+  first, then verifies each phase in turn. Use a task whose implement phase
+  genuinely runs long.
+- **A state-file edit does not survive a running worker.** It holds sessions in
+  memory and writes them back. Suspend, edit, then `sudo systemctl restart`.
+  Resuming lets the old copy win. Setting `handoff_requested` on the session is
+  the production rotation lever.
+
+Progress is withheld from a **review** successor on purpose
+(`internal/agentctx/agentctx.go:321`), because an independent review must
+reconstruct the change from the diff. That absence is not the defect.
+
+## F61 and F62, recorded and not built
+
+**F61: the planner learns the verification policy by refusal.** The brief says
+a policy exists, not what is in it. Every plan therefore pays one refused round
+trip. The recovery loop works: run 14's planner consumed the refusal and
+resealed 31 seconds later. It is not a one-liner, because `agentctx.Input.Policy` is filled
+from the worker's `SafeOperations` while the verification policy is
+coordinator-side. The reason to promote it later is local models, which may
+propose forbidden commands repeatedly because they cannot infer the allowed
+substitute.
+
+**F62: a requested handoff nobody answers is invisible.** The rotation is
+agent-driven. In run 16 the agent never wrote `HANDOFF.md`, renewals stopped,
+the lease expired, and the task lost an attempt. Worker health recorded only
+`agent status idle and pane unchanged`, 34 times. There is no timeout, no
+retry, and no observation saying a handoff was requested and left unanswered.
+The expiry is indistinguishable from an ordinary idle one.
+
+## Live state
+
+Three pull requests are open and unreviewed:
+
+```text
+06G4M6HF1Z3EREX1X3NEKSHP24  pulls/18
+06G4M8WHGQ4P3GQMPEEH0RJRHM  pulls/19
+06G4SWEVP71FYYKAV5FV0ZK5ZG  pulls/20
+```
+
+Both workers are online on `34f3c28` with no release transactions and no
+sessions. 29 blocked `test-e2e` tasks are burn-in debris. Three `correx` tasks
+are queued and unschedulable, because `correx` has no entry in the
+coordinator's `config.jsonc`.
+
+**opencode now runs.** The model was the problem, and `hy3-free` works. It then
+stops on a permission prompt, because `~/.config/opencode/opencode.jsonc` sets
+`"bash": "ask"`. Orchestra can answer that exact dialog, but only when an
+operator queues `grant_approval`, so unattended work stalls on the first
+command. Set `"bash": "allow"` for unattended runs. That file also has no
+top-level `model` key, so OpenCode picks whatever sits at the top of
+`~/.local/state/opencode/model.json`, which any manual pick silently changes.
+
+**The opencode adapter is now a debt item, not a curiosity.** It cannot resolve
+a session file. Activity therefore reads `unknown`, and the worker cannot tell
+finished from never-started. The debt projection surfaced it independently as
+the top recurring operational item.
+
+## Things that will bite
+
+- **Background python tasks get killed here.** Three watchers died before doing
+  anything. Foreground polling and the `Monitor` tool both work.
+- **`/v1/events` is one line of JSON.** A `grep` for two substrings matches
+  across unrelated tasks. Parse it.
+- **`npx` and `./node_modules/.bin/*` fail on this filesystem.** Call node
+  directly.
+- **`rm` and `cp` are interactive.** Use `/bin/rm -f` and `install`.
+- **Secrets are guarded.** Expand a token inside the container in one remote
+  command:
+  `T=$(docker exec orchestra-api printenv ORCHESTRA_TUI_TOKEN); curl -s -H "X-Orchestra-Surface: tui" -H "Authorization: Bearer $T" ...`
+- **Rebuild the coordinator from a detached worktree**, and split the worktree
+  add, the docker build and the compose up into separate commands.
+- **`deploy/build.sh` builds both halves from one commit with one stamp.** Use
+  it.
+- **Geist is not on disk.** Both stacks fall back to system faces, and the
+  ethos threat model rules out the font CDN.
+
+## Resume in this order
+
+Set by the operator at the session boundary. Do not rebuild it from the commits.
+
+1. **F62 first.** Make a requested-but-unanswered handoff visible and bounded.
+   Preserve the lease while Orchestra is explicitly waiting, retry the confirmed
+   request, then emit a causal timeout. Today it ends as generic idleness.
+2. **Repeat the implement-successor rung** with a deliberately longer task. Get
+   at least one `PlanPhaseVerified`, force the handoff while still in
+   `implement`, and prove the successor sees the complete accepted plan, the
+   verified previous phase, the first unfinished phase, and the current human
+   authority.
+3. **Finish the remaining ladder.** Manual verification, SHA staleness and
+   reverification, human-decision mismatch, then a real replan with old-plan
+   provenance.
+4. **Use the capability table above as backend work discovery.** Do not add fake
+   controls. Each disabled action is concrete evidence of a missing capability.
+5. **Continue the debt slices independently.** Durable worker observations and
+   manual-intervention events are the next evidence gaps. Not automatic
+   maintenance yet.
+
+## What the tag means
+
+```text
+orchestra-release-v1 -> 34f3c28
+  deployed, settled lifecycle plus the truth-detector UI baseline
+
+later HEADs
+  experimental plan, debt and runtime work that must earn their own
+  release proof
+```
+
+Use that distinction. A defect found in experimental work is not a reason to
+reopen settled architecture.
+
+## The roadmap the operator set
+
+```text
+A. runtime correctness   finish the plan-machinery live proof
+B. evidence and debt     durable worker observations, manual-intervention
+                         events, then rerun the projection
+C. operator surface      first-class HumanDecision write API,
+                         effective project-config read API,
+                         session and context health projection
+D. adapter               fix opencode activity and session resolution
+E. UI                    wire capabilities as backend support becomes real
+```
+
+The framing that ties them together is the thing to keep. The UI says what
+Orchestra cannot expose or control. The debt ledger says which of those
+shortcomings repeatedly costs something. The burn-in says which runtime
+semantics are reliable. Those three decide what gets built next.
+
+One design question to settle before B's slice two writes any code. The worker
+ring is bounded and lossy by construction. Ingesting it durably means deciding
+whether the coordinator stores every observation as an event, or only
+transitions. Storing every heartbeat's ring would write the same 41-count
+observation hundreds of times.

+# orchestra web control ui
+
+status: mockup specification
+app: orchestra
+shared design system: ethos
+accent: signal violet `#8F7AE5`
+motif: routing fork
+primary operator: single infrastructure operator
+
+## 1. purpose
+
+orchestra's web ui is an operator console for understanding and steering agent work without reconstructing state from logs, tmux sessions, gitea, or the event stream.
+
+it has three jobs:
+
+1. show what needs the operator now.
+2. show what orchestra believes and what an agent is actually doing.
+3. expose intervention and forensic detail without making the default screens noisy.
+
+it is not a generic project-management product, an analytics dashboard, or a chat-first interface.
+
+## 2. ethos application
+
+orchestra inherits the ethos shell and neutral system unchanged.
+
+### fingerprint
+
+- accent: signal violet `#8F7AE5`
+- motif: routing fork
+- accent use: active navigation, focus, selected phase, primary operator action, routing/transition marks
+- motif use: app mark, phase transitions, routing state, empty states, one hero/detail moment
+
+suggested token block:
+
+```css
+[data-app="orchestra"] {
+  --accent:      #8F7AE5;
+  --accent-hi:   #A291EC;
+  --accent-dim:  rgba(143, 122, 229, 0.14);
+  --accent-line: rgba(143, 122, 229, 0.32);
+  --accent-glow: rgba(143, 122, 229, 0.22);
+}
+```
+
+### type
+
+- geist sans: labels, task names, explanations, buttons, headings, operator-authored prose
+- geist mono: task ids, epochs, worker ids, pane ids, timestamps, percentages, context counts, revisions, paths, refs, sha values, lease durations
+- machine values must never silently use sans for visual convenience
+
+### surfaces
+
+- page room: `--bg-0`
+- normal panel: `--bg-1`
+- selected/raised content: `--bg-2`
+- hover: `--bg-3`
+- borders: 1px `--line`, `--line-hi` only where selection or risk needs stronger separation
+- no blur or glass
+- accent never washes a whole content panel
+
+### motion
+
+all ui transitions use ethos mechanical motion: 130–170 ms, `cubic-bezier(0.2, 0, 0, 1)`, no spring or bounce.
+
+## 3. shared shell
+
+### desktop
+
+- 64px vertical icon rail
+- 56px top bar
+- main content fills remaining viewport
+- global `cmd+k` command/search surface in the top bar
+- right side of top bar shows only high-value machine state: orchestra revision, live state, current time
+
+primary navigation:
+
+1. dashboard
+2. tasks
+3. decisions
+4. workers
+5. projects
+6. review
+7. settings
+
+terminal is entered from a task or worker and does not need permanent primary navigation.
+
+### mobile
+
+- rail becomes bottom navigation with no more than five primary items
+- secondary pages move behind task/project drill-down or header menus
+- machine readouts relocate into detail screens rather than disappearing
+- terminal remains a dedicated full-screen view
+
+## 4. information hierarchy
+
+orchestra should visually distinguish five classes of information.
+
+| class | meaning | treatment |
+|---|---|---|
+| operator authority | human decision, correction, constraint | high prominence, accent signal |
+| verified orchestra state | lifecycle, lease, phase, review, refs | neutral surfaces, machine values in mono |
+| agent claims | proposed plan, handoff text, self-reported risk | visibly labeled as agent-supplied |
+| historical/superseded | stale plan, previous handoff, old decision | muted, never visually dominant |
+| fault/attention | blocked, refused, stale, mismatch | status color + explicit reason |
+
+raw events and implementation details are drill-down evidence, not default-page content.
+
+## 5. dashboard
+
+mockup: `final/01-dashboard.png`
+
+purpose: answer "what needs me, what is running, and is the system healthy?"
+
+### layout
+
+three primary regions only:
+
+1. **needs your attention**
+   - trajectory gate
+   - blocking human decision
+   - pr awaiting review
+   - closed-without-merge/operator-required state
+   - one line explaining why each item needs the operator
+
+2. **running tasks**
+   - task name/id
+   - current phase
+   - worker/harness
+   - last real progress
+   - context occupancy
+   - lease timing
+   - compact routing-fork phase indicator
+
+3. **system state and capacity**
+   - workers online/available
+   - quota status
+   - active leases
+   - router queue/rejection state
+   - source reconciliation
+   - herdr health
+
+### rules
+
+- no disk, cpu, ram, or generic host-monitor metrics unless they directly block orchestration
+- no vanity charts
+- health should show actual counts/times, not vague "running" indicators
+- dashboard actions should navigate to the relevant task/review/worker rather than becoming an operator-control surface itself
+
+## 6. tasks list
+
+mockup: `final/04-tasks.png`
+
+purpose: browse all work under orchestra and locate a task quickly.
+
+### groups
+
+- needs attention
+- running
+- waiting/queued
+- completed
+- failed
+
+### row fields
+
+- task title/id
+- project
+- current phase
+- compact routing-fork phase path
+- worker/harness when assigned
+- last update/progress
+- context occupancy for active sessions
+- status
+
+### filters
+
+- project
+- phase
+- worker/harness
+- status
+- attention state
+
+avoid turning this into a kanban board. orchestra's lifecycle is stateful and event-backed; the list should expose state, not encourage arbitrary drag-and-drop mutation.
+
+## 7. task detail
+
+mockup: `final/02-task-detail.png`
+
+purpose: provide one calm page answering "what are we doing?", "what is happening?", and "where are we in the workflow?"
+
+### top area
+
+- title
+- task id
+- project
+- current phase
+- steer/correct primary action
+- secondary actions menu
+
+### what we're doing
+
+show only:
+
+- goal
+- acceptance summary
+- latest effective human decisions when present
+- active constraints when present
+
+full contract, all decisions, and historical versions open in drill-down views.
+
+### live execution
+
+show only:
+
+- worker/harness
+- pane
+- lease remaining
+- context occupancy
+- last progress
+- one-line current activity
+
+links:
+
+- open live pane
+- worker logs
+- launch context
+- git diff
+
+### workflow
+
+render the ace-fca path visibly:
+
+`frame → research → plan → implement → review → pr → merged`
+
+completed phases are quiet green, current phase uses the orchestra accent, future phases remain neutral.
+
+phase detail, artifacts, refusal history, and raw events belong in drill-downs rather than the default task screen.
+
+## 8. live pane / terminal
+
+mockup: `final/03-terminal-live-pane.png`
+
+purpose: show the actual tmux/herdr pane, not a reconstructed log view.
+
+### behavior
+
+- read-only by default
+- exact pane dimensions and terminal rendering preserved when possible
+- fit mode may scale visually but must not alter the underlying pane
+- scrollback inspection must not disturb the live cursor
+- `take control` explicitly enables keyboard forwarding
+- strong visual state when control is captured
+- escape or a fixed shortcut releases control
+
+### why this screen exists
+
+it must reveal real tui state such as:
+
+- input still sitting in the editor
+- queued input
+- paste placeholders
+- permission/approval dialogs
+- `/clear`
+- `@HANDOFF.md`
+- agent busy/idle presentation
+- tmux status line and pane identity
+
+### surrounding chrome
+
+keep it minimal:
+
+- worker/pane identity
+- read-only/control state
+- fit/copy/scrollback controls
+- lease epoch/timing
+- context occupancy
+- last verified progress
+- pane/worker health
+- small live event strip for orchestra-originated interactions and confirmations
+
+when a pane is lost, preserve the last captured frame and state the exact loss time and lease consequence.
+
+## 9. decisions list
+
+mockup: `final/05-decisions.png`
+
+purpose: inspect durable human authority and approvals across tasks.
+
+this is not the human attention queue; that is review.
+
+### list fields
+
+- decision id
+- short decision text
+- task
+- phase
+- source/provenance
+- requested/recorded time
+- status: active, superseded, waiting, approved, rejected, auto
+- operator/actor
+
+### filters
+
+- active/superseded
+- kind: decision, correction, constraint, answer, scope change
+- project
+- task
+- actor/source
+
+### detail
+
+opening a decision should show:
+
+- exact value
+- subject
+- provenance
+- supersedes/superseded-by links
+- event sequence
+- effective authority impact
+
+machine provenance is mono; the human decision text remains sans.
+
+## 10. workers
+
+mockup: `final/06-workers.png`
+
+purpose: answer "where can work run and is that execution machinery usable?"
+
+### worker list fields
+
+- worker/harness identity
+- online/idle/busy/offline/degraded
+- harness type
+- current task when leased
+- phase
+- lease or heartbeat age
+
+intentionally omit generic infrastructure metrics such as disk, memory, cpu, and uptime unless orchestra directly uses them for eligibility.
+
+### worker detail
+
+- current session/task
+- pane id
+- lease epoch/remaining
+- last verified progress
+- worker revision
+- herdr status
+- last heartbeat
+- projects declared by the worker
+- declared capabilities if orchestra actually consumes them
+
+### capabilities
+
+capabilities must come from worker registration/project configuration, never be guessed from host inspection.
+
+the ui labels them **declared capabilities** and can expose registration provenance.
+
+### registration
+
+registration is worker-driven:
+
+1. worker starts with coordinator credentials/configuration
+2. worker announces identity, revision, harnesses, projects, capacity and declared capabilities
+3. coordinator records it and heartbeat updates liveness
+
+`add worker` should therefore be a registration guide/bootstrap flow, not a magical browser-side creation of a remote process.
+
+## 11. projects
+
+mockup: `final/07-projects.png`
+
+purpose: group long-running repository/workflow configuration and its active work.
+
+### project list
+
+- project name
+- short description
+- state
+- active/total task count
+- attention/decision count
+- last meaningful activity
+
+avoid aggregate artifact counts or infrastructure metrics unless they help choose an action.
+
+### project detail
+
+- description
+- source/repository identity
+- configured worker/harness affinity
+- workflow phases
+- trajectory-gate policy
+- quality gate
+- human reconcile source
+- safe-operation policy
+- active tasks
+- recent meaningful events
+
+configuration edits belong in the project detail, while global defaults remain in settings.
+
+## 12. review
+
+mockup: `final/08-review.png`
+
+purpose: the operator inbox: **what needs me to look at something and judge?**
+
+workers show machinery. review shows human attention.
+
+### review item types
+
+- trajectory decision
+- human blocker / decision request
+- code/pr review
+- ai review requiring operator override
+- operator-required lifecycle state
+- closed pr without merge
+- information/fyi, optionally hidden by default
+
+### list fields
+
+- type
+- task/item
+- why it is here
+- project
+- priority
+- age
+
+worker/pane is secondary metadata, not a primary column.
+
+### detail drawer/page
+
+show the minimum evidence needed to act:
+
+- why this needs the operator
+- effective task goal/constraints relevant to the decision
+- proposed options when applicable
+- relevant plan/diff/review evidence
+- provenance and age
+- comments/context drill-down
+
+primary action names must match the lifecycle action: make decision, answer blocker, review pr, request changes, retry, etc.
+
+snooze/defer may exist for attention management but must not silently mutate underlying task truth.
+
+## 13. settings
+
+mockup: `final/09-settings.png`
+
+purpose: configure orchestra itself, project-independent defaults, integrations, policies, and operator/security settings.
+
+### tabs
+
+1. general
+2. appearance
+3. notifications
+4. access & security
+5. integrations
+6. agents & tools
+7. policies
+8. advanced
+
+### general
+
+- instance name/environment
+- locale/time display
+- default task preferences
+- default workflow policy
+- event/artifact retention
+- storage/backup state only if orchestra owns it
+
+### appearance
+
+- theme: system/dark/light
+- ethos remains fixed; no arbitrary shell redesign controls
+- accessibility and reduced motion
+
+### access & security
+
+- surface tokens/status
+- trusted review actors
+- ignored actors
+- operator sessions
+- agent-surface auth
+- secret/config source status without exposing secret values
+
+### integrations
+
+- gitea
+- vikunja
+- notification sinks
+- source reconciliation state
+
+show endpoint/identity and last successful interaction in mono.
+
+### agents & tools
+
+- harness definitions
+- adapter/runtime configuration
+- tmux/herdr ownership
+- default launch behavior
+- context occupancy thresholds
+
+### policies
+
+- work phase defaults
+- trajectory gate
+- bounded decision request budget
+- retry policy
+- reconcile failure handoff threshold
+- quality/review/submission policy
+
+### advanced
+
+- event-store diagnostics
+- snapshots/replay
+- raw configuration
+- migration/status information
+- destructive operator actions in a visually separated danger zone
+
+## 14. global command surface
+
+`cmd+k` is the shared ethos command surface and should handle navigation plus safe operator actions.
+
+examples:
+
+- open task by id/title
+- open worker/pane
+- show decisions for task
+- steer/correct active task
+- answer current blocker
+- retry failed task
+- open review item
+
+high-risk lifecycle actions require explicit confirmation and should not be the first fuzzy-search result for ordinary text.
+
+## 15. status grammar
+
+status is compact and consistent across screens.
+
+recommended semantic colors:
+
+- green: verified healthy/completed/accepted
+- violet: current/selected/orchestra-controlled active state
+- amber: waiting/degraded/operator attention
+- red: failed/refused/danger
+- gray: idle/unknown/historical
+
+color never carries the entire meaning; every state also has text/iconography.
+
+## 16. evidence drill-down
+
+any important derived claim should be traceable without ssh.
+
+from relevant detail screens the operator should be able to reach:
+
+- event(s) that established the state
+- exact generated launch context
+- sealed research/plan/review/submission artifact refs
+- git sha/ref
+- worker journal observations
+- input confirmation receipt
+- pane capture/terminal
+- source comment/review provenance
+
+raw evidence is accessible but not visible by default.
+
+## 17. copy rules
+
+- labels describe what the operator controls, not implementation class names
+- machine values remain exact and honest
+- errors state what failed and what consequence follows
+- no "something went wrong"
+- no spinner where a queue depth, heartbeat age, poll timestamp, retry time, or progress value exists
+
+examples:
+
+- `source reconcile failed · retry at 14:06:00`
+- `worker heartbeat 42s old · ineligible after 60s`
+- `phase request refused · next phase is research`
+- `pane lost at 13:42:18 · lease expires in 09:14`
+
+## 18. responsive behavior
+
+### tablet/mobile priorities
+
+keep visible:
+
+1. attention state
+2. task title/phase
+3. latest human authority
+4. live execution state
+5. primary action
+
+collapse or drill down:
+
+- long acceptance lists
+- complete workflow history
+- detailed lease metadata
+- worker journal
+- raw events
+- project configuration
+
+terminal becomes its own full-screen route and should not be squeezed into a card.
+
+## 19. implementation order
+
+recommended web-ui build order:
+
+1. ethos shell + orchestra tokens/motif
+2. dashboard
+3. tasks list
+4. task detail
+5. live pane
+6. review inbox
+7. decisions list/detail
+8. workers
+9. projects
+10. settings
+11. global command surface
+12. evidence/raw-event drill-down
+
+build each screen against real orchestra api data rather than static ui-only state as early as practical.
+
+## 20. verification
+
+for every screen:
+
+- render and visually inspect pixels
+- check desktop and <=640px mobile layout
+- assert no horizontal overflow
+- verify mono/sans split visibly
+- verify accent is signal-only
+- verify no blur/backdrop-filter exists
+- verify empty/error/loading states show real machine state
+- compare implemented screen against the corresponding mockup as direction, not pixel-perfect contract
+
+mockups communicate hierarchy, density, and interaction intent. orchestra state and the ethos design laws are the actual specification.
