+## 11 — Orchestration · T10.x
+
+Fills §17's deferred line — multi-agent orchestration, revisited now that
+cross-agent coordination is real. A `Reconciler` port picks up a run at its
+existing `Verified`/`Graded`/`Ungraded` resting states, decides what runs
+next toward a `GoalId`-scoped objective, and dispatches through Kafka via
+the same outbox/inbox discipline T7.4 established — never a direct spawn
+call. An HTTP surface binds one method table shared with T9.2's eventual
+stdio transport. Two front doors, one IR: `tasks/*.md` parsed directly
+(door a), or a free-text problem statement drafted and parked in
+`Suspended` for human approval before it runs (door b).
+
+Depends on T1.x, T2.1/T2.3, T3.x, T7.3/T7.4, T9.1 landing first; not blocked
+on T9.2–T9.6 (the stdio binding develops in parallel against the same
+method table T10.4 authors).

+## Goal
+
+New identity `GoalId(Ulid)` grouping runs that share an objective, optional at
+spawn. Extend `T1.7`'s query surface to read across `RunId`s sharing one
+`GoalId`.
+
+## Facts (inlined — no spec read needed)
+
+- `GoalId` is tenant-scoped like `RunId`, **not** `TaskId`. `TaskId` is already
+  the grading comparison-group key (§11.5) — reusing it corrupts
+  group-epoch/quorum semantics the learning loop depends on.
+- Attaching `goal_id` at spawn is **optional**. A run with no `GoalId` behaves
+  exactly as today — this is additive, not a required field.
+- `GoalView` is a new, separate query. It does not replace per-run
+  `EpisodeView`; it lists member `RunId`s and references their existing
+  metadata, no duplication.
+- Same parity rule as T1.7: `GoalView` from materialized state must equal
+  `GoalView` from a cold re-fold (T0.8's property applied here too).
+
+## Steps
+
+1. Declare `GoalId(Ulid)` in the `ids` crate, alongside `RunId`.
+2. Add optional `goal_id: Option<GoalId>` to run-spawn input and the run
+   record.
+3. Index runs by `(TenantId, GoalId)` in materialized state.
+4. Define `GoalView { goal: GoalId, runs: Vec<RunSummary> }`, `RunSummary`
+   referencing existing run metadata — do not duplicate `EpisodeView` fields.
+5. Implement the query against materialized state and against cold re-fold.
+6. Test: two runs sharing a `GoalId`, one plain run with none; assert
+   `GoalView` returns exactly the two, in spawn order.
+
+## Acceptance
+
+- Two runs sharing a `GoalId` are both returned by `GoalView`; a run with no
+  `GoalId` never appears in any `GoalView`.
+- `GoalView` from materialized state equals `GoalView` from cold re-fold.
+
+## Verify
+
+**Harness:** two runs sharing a `GoalId`, one run with no `GoalId`, one
+branch/rewind case reused from `T1.7`'s harness.
+
+**Integration test** — `tests/it_goal_view_equivalence.rs`:
+1. Spawn run A and run B both with `goal_id=G`; spawn run C with none.
+2. Query `GoalView(G)` from materialized state → `view_a`.
+3. Drop state tables; query again via cold re-fold → `view_b`.
+4. Assert `serialize(view_a) == serialize(view_b)`.
+5. Assert `view_a` contains exactly `{A, B}`, never `C`.
+6. Assert order is spawn order, stable.
+
+**Command:** `cargo test -p query goal_view_equivalence`
+
+**False pass:**
+- Testing only one run per goal — a grouping bug is invisible with a single
+  member.
+- Skipping the "run without `goal_id`" exclusion check. A filter that
+  defaults to "all runs" passes silently without it.
+
+## Traps
+
+- Deriving `GoalId` from `TaskId` "since they're both groupings." Different
+  lifecycle, different owner — grading vs orchestration.
+- Making `goal_id` required at spawn. Breaks every existing plain-workflow
+  spawn call.

+| Status | Not started |
+| Flags | gate |

+
+## Goal
+
+Prove the properties no single T10.x task owns: a full goal chain survives a
+real Kafka outage, dispatch is idempotent under forced redelivery,
+`Suspended`-approval produces byte-identical IR to hand-authored YAML, and
+the HTTP method table stands as a published artifact.
+
+## Facts (inlined — no spec read needed)
+
+- Mirrors T7.4's fault-injection shape — broker down for the whole test —
+  extended across the full events → reconcile → dispatch → inbox-relay →
+  spawn loop, not just outbox delivery.
+- Front-door equivalence for door (b) extends T3.10's existing hash-equality
+  gate — same discipline, new door.
+- Gate script follows board convention: one script, diffed against a
+  committed expected output, empty diff is the only pass.
+
+## Steps
+
+1. Compose a fixture: one goal, a 2-run chain (A → reconcile → B → reconcile
+   → `Stop`), driven through real HTTP calls and real Kafka topics.
+2. Kill the broker mid-chain — after A completes, before the dispatch
+   message for B is consumed; assert the chain still completes once the
+   broker returns, with B eventually spawned.
+3. Force redelivery of the `.dispatch` message for B; assert exactly one
+   run B exists.
+4. Submit a problem statement through door (b), edit the draft, approve;
+   separately hand-author the identical edited content as YAML and load it
+   through door (a); assert both `WorkflowVersion` hashes match.
+5. Snapshot the HTTP method table (paths + request/response shapes) to a
+   committed fixture; assert no path removed and no field removed relative
+   to the fixture — additions are fine, removals fail the gate.
+6. Assert a goal-stall metric fires for a deliberately broken `Reconciler`
+   on one goal while a healthy goal in the same tenant proceeds unaffected
+   (T10.8's concurrency claim, at gate scope).
+
+## Acceptance
+
+- All six checks above pass with an empty diff against
+  `verify/expected/T10.10.txt`.
+
+## Verify
+
+**Harness:** full stack — embedded `redb`, real Kafka (or the board's
+chosen fault-injection substrate), `axum` API instance, stub `Reconciler`
+with scripted multi-step decisions.
+
+**Integration test** — `tests/it_p10_composition_gate.rs`, one numbered
+assertion per Steps item above (`a1`..`a6`), reported by name per the
+board's script convention.
+
+**Command:** `verify/T10.10.sh`, diffed against `verify/expected/T10.10.txt`.
+
+**False pass:**
+- Running the chain with the broker never actually taken down — the
+  "survives an outage" claim needs the outage to really happen mid-chain,
+  not just be configured as theoretically tolerable.
+- Skipping the method-table snapshot diff — a route or field silently
+  removed here breaks every embedder bound to the table (HTTP today, stdio
+  later) without any single T10.x task's own tests catching it, since none
+  of them own the whole table.
+
+## Traps
+
+- Treating this gate as "run all T10.x tests together." It must assert
+  properties none of them individually assert, per the board's own gate
+  discipline (INDEX.md, "Verification practice," point 5).
+- Committing the method-table fixture as freeform prose instead of a
+  diffable, structured snapshot. An unreviewable diff defeats the point of
+  having a fixture at all.

+| Status | Not started |

+
+## Goal
+
+New port answering "how far toward the goal, what next" from a run's terminal
+resting state — distinct from `Verifier` (fail-closed pass/fail) and `Judge`
+(relative-only comparison).
+
+## Facts (inlined — no spec read needed)
+
+- `Verifier::verify` is fail-closed pass/fail (rust-agentic-sys.md §10).
+  `Judge::compare` is deliberately relative-only, "cannot return an absolute
+  score" (rust-agentic-sys.md §11.1). "How far toward goal, what next" is a
+  third question — forcing it through either port blurs a firewall built on
+  purpose. `Reconciler` is new, sized like `Verifier` (one method, S/M).
+- Fires **only** off `Verified{pass|fail}`, `Graded`, `Ungraded` — states
+  `T1.3` already designed to rest in, never resolved inline.
+- Reconciler failure degrades the record, never the run — same principle as
+  §1: "the framework cannot break the agent it runs." A `Reconciler` error or
+  timeout leaves the run at its terminal state; the goal simply does not
+  advance until retried.
+- The decision does **not** spawn anything itself. Spawning happens only
+  through the admission path (T10.3) via the inbox relay (T10.7) — never a
+  direct call from the `Reconciler` or its caller.
+- One new `#[non_exhaustive]` `WorkEvent` variant for provenance:
+  `SpawnedFromReconciliation{goal_id, parent_run, decision_ref}`. Added, not
+  replacing any existing variant.
+
+## Steps
+
+1. Define `ReconcileCtx` — `GoalId`, `GoalView` (T10.1), the just-terminal
+   run's `EpisodeView`, `WorkflowDef`.
+2. Define `ReconcileDecision` — `SpawnNext{workflow_ref, input, dispatch_key}`,
+   `Retry{step}`, `Stop{reason}`.
+3. Define the trait:
+   ```rust
+   #[async_trait]
+   pub trait Reconciler: Send + Sync {
+       fn id(&self) -> ReconcilerId;
+       async fn reconcile(&self, cx: &ReconcileCtx) -> Result<ReconcileDecision>;
+   }
+   ```
+4. Wire the trigger: on a run reaching `Verified`/`Graded`/`Ungraded` with a
+   `GoalId` set, call the `Reconciler` bound to that goal.
+5. On `Reconciler` error or timeout: log, leave the run at its terminal state,
+   do not auto-retry — matches `Verifier`'s explicit-only-retry discipline.
+6. Add `WorkEvent::SpawnedFromReconciliation`, written on the **next**
+   spawned run's first log record, referencing `parent_run` and the decision.
+7. Test with a stub `Reconciler` against all three trigger states.
+
+## Acceptance
+
+- A run reaching `Verified{pass}` with a `GoalId` triggers exactly one
+  reconcile call.
+- The decision is durably recorded and traceable from the next spawned run
+  back to the parent run and goal.
+- A `Reconciler` error leaves the run at its terminal state and does not
+  crash the executor.
+
+## Verify
+
+**Harness:** stub `Reconciler` returning each decision variant in turn; one
+goal with a 2-run chain.
+
+**Integration test** — `tests/it_reconciler_trigger.rs`:
+1. Run A (goal G) reaches `Verified{pass}`; assert `reconcile()` called
+   exactly once with the correct `ReconcileCtx`.
+2. Stub returns `SpawnNext`; assert the decision is persisted, referencing
+   run A.
+3. Assert the next spawned run's first log record carries
+   `SpawnedFromReconciliation{goal_id: G, parent_run: A, decision_ref}`.
+4. Repeat for `Graded` and `Ungraded` trigger states.
+5. Stub `Reconciler` panics or times out; assert run A stays at its terminal
+   state, no crash, no infinite retry.
+6. Run with no `GoalId` reaches `Verified{pass}`; assert `reconcile()` is
+   never called.
+
+**Command:** `cargo test -p kernel reconciler_trigger`
+
+**False pass:**
+- Asserting reconcile "ran" via a boolean flag instead of asserting the
+  `WorkEvent` provenance record exists — passes even if a crash lost the
+  decision before persistence.
+- Testing only `Verified{pass}`, skipping `Graded`/`Ungraded` — those are the
+  states most likely miswired, being newer additions to the FSM.
+
+## Traps
+
+- `Reconciler` spawning the next run directly. Violates "never bypass the
+  admission path" — see T10.3/T10.7.
+- Overloading `Judge::compare` to also answer "what next." Collapses a
+  boundary `Judge`'s signature deliberately enforces (rust-agentic-sys.md
+  §11.1, "deliberately cannot return an absolute score").
+- Auto-retrying a failed `Reconciler` call with no cap — a broken impl then
+  spins forever against every terminal run in the tenant.

+
+## Goal
+
+`dispatch_key` on spawn requests: a redelivered spawn request (from Kafka
+at-least-once delivery, T10.7) becomes a no-op insert instead of a duplicate
+run.
+
+## Facts (inlined — no spec read needed)
+
+- Same principle as the outbox's `(BranchKey, Lsn)` fold-key idempotency
+  (T7.4) — exactly-once is achieved at the admission boundary, not in
+  transport.
+- `dispatch_key` is caller-supplied, opaque, unique per intended spawn — e.g.
+  a `Reconciler` decision id.
+- Admission with no `dispatch_key` behaves exactly as today. This is
+  additive, not a required field.
+
+## Steps
+
+1. Add optional `dispatch_key: Option<String>` to spawn-run input.
+2. Add a unique index on `(TenantId, dispatch_key)` where `dispatch_key` is
+   set.
+3. On spawn: if `dispatch_key` is set and already seen, return the existing
+   `RunId` instead of creating a new run — no error, no duplicate.
+4. Test redelivery: same `dispatch_key` submitted twice, concurrently and
+   sequentially.
+
+## Acceptance
+
+- Two spawn calls with the same `dispatch_key` produce exactly one run; the
+  second call returns the first run's `RunId`.
+- Spawn calls with no `dispatch_key` are unaffected.
+
+## Verify
+
+**Harness:** spawn endpoint (T10.4) or direct kernel call, two concurrent
+callers.
+
+**Integration test** — `tests/it_idempotent_admission.rs`:
+1. Spawn with `dispatch_key=K`; assert one run created, `RunId=R`.
+2. Spawn again with `dispatch_key=K`; assert no new run created, returned
+   `RunId == R`.
+3. Fire 20 concurrent spawn calls with the same `dispatch_key`; assert
+   exactly one run exists after all resolve.
+4. Spawn with no `dispatch_key` twice; assert two distinct runs (unaffected
+   baseline).
+
+**Command:** `cargo test -p kernel idempotent_admission -- --test-threads=1`
+
+**False pass:**
+- Testing only sequential redelivery. Concurrent redelivery is the actual
+  failure mode under Kafka rebalance/retry and needs the unique-index race
+  caught, not a check-then-insert race.
+
+## Traps
+
+- Making `dispatch_key` required. Breaks every direct/manual spawn call that
+  isn't part of a goal chain.
+- Deduping by a hash of `(workflow_ref, input)` instead of the caller-supplied
+  key. Two legitimately identical requests would then silently collapse into
+  one run.

+## Goal
+
+`axum` HTTP service binding one method table — spawn / status / stream /
+episode / transcript / rewind / cancel / retry / goal / metrics — to
+`poimen-sdk` ports. One method set: HTTP today, the same table T9.2's stdio
+JSON-RPC binds to later.
+
+## Facts (inlined — no spec read needed)
+
+- **The protocol is a published artifact** — INDEX.md's own rule for the
+  sidecar applies equally here: methods added, never repurposed; fields
+  added, never removed, from the first commit.
+- HTTP is a transport binding onto `poimen-sdk` (T9.1), not a bespoke access
+  layer with its own business logic. Handlers translate, they do not decide.
+- `/v1/problems` and `/v1/plans/{id}/approve|reject` route to T10.6's
+  workflow, not implemented here — this task defines the routes and
+  request/response contracts; T10.6 fills in plan-draft semantics.
+- `/v1/runs/{id}/stream` tails the same committed log the outbox relay reads
+  — SSE, not a second read path.
+
+## Steps
+
+1. Stand up the `axum` service, one route module per resource: runs, plans,
+   goals, metrics.
+2. `POST /v1/runs` → spawn_run. Request `{tenant, workflow_ref, input,
+   goal_id?, dispatch_key?}`. Response `{run_id, status}`.
+3. `GET /v1/runs/{id}`, `/episode` (T1.7), `/attempts/{step}/{n}/transcript`
+   (T1.6 `BlobRef` dereference), `/stream` (SSE).
+4. `POST /v1/runs/{id}/rewind` (T2.3), `/cancel`, `/attempts/{step}/retry`
+   (T1.4).
+5. `GET /v1/goals/{id}` (T10.1 `GoalView`).
+6. `GET /v1/metrics`, `/v1/runs/{id}/metrics` (T8.2's existing list, scoped).
+7. Auth/tenant resolution: reject any request without a resolvable
+   `TenantId` before touching the kernel — no implicit tenant.
+8. Version the route set from commit one: additive only, document the rule
+   inline in the router module.
+
+## Acceptance
+
+- Full request/response cycle for spawn → poll → episode → transcript
+  against an embedded `redb` backend.
+- Rewind, cancel, retry each produce the same log-level effect as calling
+  the underlying kernel function directly — no HTTP-layer divergence.
+
+## Verify
+
+**Harness:** embedded `redb`, stub model, `axum` test client
+(`tower::ServiceExt::oneshot`).
+
+**Integration test** — `tests/it_http_api_surface.rs`:
+1. `POST /v1/runs`; assert 200 with `run_id`; assert kernel shows
+   `Scheduled`.
+2. `GET /v1/runs/{id}` until terminal; assert status matches kernel state
+   exactly at each poll.
+3. `GET /v1/runs/{id}/episode`; assert shape matches T1.7's `EpisodeView`,
+   includes failed attempts.
+4. `GET /v1/runs/{id}/attempts/{step}/{n}/transcript`; assert returned bytes
+   match `BlobStore` content directly (T1.6).
+5. `POST .../rewind`; assert new `BranchId` created, parent branch still
+   readable via all-branches.
+6. `POST .../retry`; assert new `AttemptNo`, prior attempt record
+   unmodified.
+7. `POST .../cancel` mid-run; assert `Cancelled` reached (matches T1.3's
+   cancel matrix).
+8. Request with no resolvable tenant; assert rejected before any kernel call
+   — instrument kernel entrypoints, assert zero calls.
+
+**Command:** `cargo test -p api http_api_surface`
+
+**False pass:**
+- Asserting HTTP 200 without checking underlying kernel state — a route that
+  accepts and silently drops a request passes this.
+- Testing transcript retrieval only for a successful attempt — failed-attempt
+  transcripts are the debugging case that matters most.
+
+## Traps
+
+- Putting business logic (retry policy, plan validation) in the HTTP
+  handler instead of the kernel/port layer. The handler is a transport, not
+  a second brain.
+- Resolving `BlobRef`s eagerly inside `/episode` "for convenience" — T4.3's
+  regression, one layer up.

+# T10.5 — `TaskBoardFormat` plugin
+
+| Field | Value |
+|---|---|
+| Phase | P10 — Orchestration |
+| Size | M — 1 to 3 days |
+| Status | Not started |

+
+## Goal
+
+Front door (a): parse `tasks/*.md` — this board's own format — into a
+`WorkflowDef` via the existing `WorkflowFormat` plugin trait. Zero kernel
+change.
+
+## Facts (inlined — no spec read needed)
+
+- `WorkflowFormat` is already designed as a plugin point — this adds a third
+  format implementation, not a new mechanism. YAML and the Rust builder are
+  the other two; both canonicalize to the same IR (INDEX.md's customization
+  contract).
+- Step order comes from **phase + row order in INDEX.md**, not
+  filename/id order. Id order is explicitly not execution order (INDEX.md's
+  own "Ordering" section).
+- Each task file's Acceptance/Verify/Command sections map to a `StepDef`'s
+  verifier binding and completion criteria. Capability ids referenced
+  (verifier/judge/model) must already be registered (T3.9) or load fails
+  naming the id and file — same contract as YAML.
+- Read-only relative to the board: this parses `tasks/*.md`, it does not
+  write `Status` back. That stays out of scope here.
+
+## Steps
+
+1. Implement `TaskBoardFormat: WorkflowFormat`, `load(path: &Path) ->
+   Result<WorkflowDef>` reading a directory of `T*.md` + `INDEX.md`.
+2. Parse `INDEX.md`'s phase tables for execution order; parse each task
+   file's Goal/Acceptance/Verify sections into one `StepDef` per task.
+3. Unresolved verifier/judge/model ids referenced in a task file fail at
+   load, naming the id and file — same contract as the other two front
+   doors.
+4. Canonicalize through the same Blake3 hashing as the other two front doors
+   (T3.1) — same `WorkflowDef` IR.
+5. Test: load this board's own `tasks/` directory, assert the canonicalized
+   IR is stable across two loads (determinism), and that step order matches
+   `INDEX.md`'s declared phase order, not directory-listing order.
+
+## Acceptance
+
+- `agent-rust/tasks/` loads into a `WorkflowDef` with step order matching
+  `INDEX.md`'s declared phase order.
+- A task file referencing an unregistered verifier id fails at load, naming
+  the id and file — not at spawn.
+
+## Verify
+
+**Harness:** this repo's own `agent-rust/tasks/` directory as the test
+fixture — self-hosting, no synthetic fixture needed.
+
+**Integration test** — `tests/it_taskboard_format.rs`:
+1. Load `agent-rust/tasks/`; assert no error.
+2. Assert step count matches `INDEX.md`'s task count.
+3. Assert step order matches `INDEX.md`'s phase-table order, not `ls`/
+   filename order — deliberately scramble the directory-read order in the
+   test harness to catch an implementation that trusts `readdir` order.
+4. Load twice; assert canonicalized `WorkflowVersion` hash identical both
+   times.
+5. Inject one task file referencing a made-up verifier id; assert load
+   fails, error names the id and file path.
+
+**Command:** `cargo test -p formats taskboard_format`
+
+**False pass:**
+- Step 3 without deliberately scrambling directory-read order — most
+  filesystems return sorted-ish order by accident, hiding a bug that trusts
+  `readdir`.
+- Skipping the unresolved-id failure test — a format that silently drops
+  unparseable tasks looks like it "works" until one goes missing at spawn.
+
+## Traps
+
+- Deriving step order from task-id string sort. `"T10.1" < "T2.1"` as
+  strings — `INDEX.md`'s declared order is the only authority, exactly the
+  bug the board's own "Ordering" section warns about at board scope.
+- Making `TaskBoardFormat` also write `Status` back into task files. Turns a
+  read-only parser into a mutator with its own concurrency/conflict
+  problems, out of scope.

+# T10.6 — `plan-draft` workflow + `Suspended`-approval flow
+
+| Field | Value |
+|---|---|
+| Phase | P10 — Orchestration |
+| Size | M — 1 to 3 days |
+| Status | Not started |
+| Flags | — |
+| Spec | inlined below |
+| Blocks | — |
+
+## Goal
+
+Front door (b): a free-text problem statement produces a draft
+`WorkflowDef`, parked in `Suspended` for human review, resumed through the
+identical loader front door (a) uses.
+
+## Facts (inlined — no spec read needed)
+
+- `Suspended` is an exact fit, verified against source: "a run awaiting
+  human approval or a webhook must not hold an executor slot" (T1.3), lease
+  released outright with no heartbeat while parked (T7.3).
+- `plan-draft` is itself an ordinary poimen workflow: a `Model` step
+  producing a `WorkflowDef` draft, no new kernel machinery.
+- The draft is validated against T3.9's capability registry **before** a
+  human ever sees it — an unresolved verifier/judge/model id in the draft
+  fails here, at draft time, not after approval.
+- Approval feeds the (possibly human-edited) draft through the **same**
+  `WorkflowFormat`/builder + T3.1 canonicalization as door (a) — this is
+  what keeps both doors on one IR without new proof machinery.
+
+## Steps
+
+1. Define the built-in `plan-draft` workflow: one `Model` step (problem
+   statement → draft `WorkflowDef`), one validation step (registry check via
+   T3.9).
+2. On draft ready, transition the `plan-draft` run to `Suspended`, releasing
+   its lease (T7.3).
+3. `/v1/plans/{id}/approve` (T10.4 route): load the (possibly edited) draft,
+   run it through the exact loader door (a)'s `WorkflowFormat`/builder uses,
+   canonicalize (T3.1), resume — matching T1.3's resume-from-`Suspended`
+   semantics.
+4. `/v1/plans/{id}/reject`: cancel from `Suspended` (legal transition per
+   T1.3's cancel-from-any-non-terminal rule).
+5. Test: submit a problem statement, assert `Suspended`, edit the draft,
+   approve, assert the resulting `WorkflowVersion` hash matches
+   hand-authoring the same edited YAML directly.
+
+## Acceptance
+
+- A submitted problem statement produces a run parked in `Suspended` with no
+  held executor slot — lease released, per T7.3's own test shape.
+- Approving a draft (edited or not) produces a `WorkflowVersion`
+  byte-identical to loading the same content by hand through door (a).
+
+## Verify
+
+**Harness:** stub model for the `plan-draft` step, embedded `redb`, T7.3's
+lease-release assertion pattern reused.
+
+**Integration test** — `tests/it_plan_draft_approval.rs`:
+1. `POST /v1/problems` with a free-text statement; assert the run reaches
+   `Suspended`.
+2. Assert the lease is released and no heartbeat is emitted while
+   `Suspended` — reuse T7.3's assertion (its step 8).
+3. Fetch the draft; edit one step; `POST /v1/plans/{id}/approve` with the
+   edited draft.
+4. Assert the resulting `WorkflowVersion` hash equals hashing the same
+   edited content loaded directly via `WorkflowFormat`/builder — front-door
+   equivalence, extends T3.10.
+5. `POST /v1/plans/{id2}/reject` on a second draft; assert it reaches
+   `Cancelled`, not stuck in `Suspended`.
+6. Draft referencing an unregistered verifier id; assert `plan-draft`'s
+   validation step fails **before** ever reaching `Suspended` — the human
+   never sees an unloadable plan.
+
+**Command:** `cargo test -p orchestration plan_draft_approval`
+
+**False pass:**
+- Skipping step 4's hash comparison and only checking "run resumed" — a
+  subtly different canonicalization from door (a) would still resume, just
+  diverge from what T3.1's guarantee promises.
+- Not testing reject — an approval-only test suite misses that `Suspended`
+  must also support "no."
+
+## Traps
+
+- Having `/approve` construct a `WorkflowDef` directly in the HTTP handler
+  instead of routing through the same loader as door (a) — this is exactly
+  the two-IR-drift bug T3.10 exists to prevent, reintroduced one layer up.
+- Skipping the registry validation step "since a human will catch it." The
+  whole point of validating before `Suspended` is that load errors are cheap
+  pre-human, expensive post-human.

+# T10.7 — Kafka topics and inbox relay
+
+| Field | Value |
+|---|---|
+| Phase | P10 — Orchestration |
+| Size | L — over 3 days |
+| Status | Not started |
+| Flags | — |
+| Spec | inlined below |
+| Blocks | T10.8 |
+
+## Goal
+
+`poimen.<tenant>.events` (outbound, existing outbox unchanged) and
+`poimen.<tenant>.dispatch` (inbound, new) — an inbox relay symmetric to
+T7.4's outbox, turning dispatch messages into spawn calls through the same
+admission path, never a raw kernel write.
+
+## Facts (inlined — no spec read needed)
+
+- Outbound is unchanged: T7.4's relay ships goal-tagged `WorkEvent`s exactly
+  as it ships every other event. No new producer logic on this side.
+- Inbound is genuinely new: the orchestrator (T10.8) publishes to
+  `.dispatch` after a `Reconciler` decision; this task builds only the relay
+  that drains it, not the orchestrator itself.
+- The inbox relay's failure-domain rule mirrors T7.4's exactly: own
+  process/task, own retry, own supervision, not co-located with the
+  executor's lifecycle.
+- Every dispatch message becomes a call to the **same** `POST /v1/runs`
+  (T10.4) the HTTP API exposes — the relay is an HTTP client to the local
+  API surface, not a kernel-internal spawn path. This is what makes the
+  "no bypass" guarantee mechanical, not a code-review convention.
+- Redelivery on `.dispatch` is handled entirely by T10.3's `dispatch_key`
+  admission dedup — the relay passes `dispatch_key` through unchanged, no
+  separate idempotency layer.
+- Partition key on both topics: `(TenantId, RunId)` per T7.5, consistent
+  with the outbox.
+
+## Steps
+
+1. Declare topics `poimen.<tenant>.events`, `poimen.<tenant>.dispatch` —
+   partition key `(TenantId, RunId)` on both (T7.5).
+2. No change to T7.4's relay beyond including goal-tagged records (already
+   covered since `GoalId` is a field on `WorkEvent`, T10.1).
+3. Build the inbox relay: consume `.dispatch`, for each message call
+   `POST /v1/runs` with `{workflow_ref, input, goal_id, dispatch_key}`
+   verbatim.
+4. Own retry/backoff on relay-to-API-call failure; never crash the relay on
+   a single bad message — dead-letter it, keep draining.
+5. Own failure domain: separate process/task, no shared lifecycle with the
+   executor or the HTTP API service.
+6. Emit inbox lag as a metric, alongside T7.4's existing outbox-lag metric.
+7. Test with the broker down for a stretch, and with forced redelivery of
+   the same dispatch message.
+
+## Acceptance
+
+- A message published to `.dispatch` results in exactly one run, even under
+  forced redelivery.
+- Broker down for the inbox side does not affect runs already in flight;
+  queued dispatch messages are processed once the broker returns.
+
+## Verify
+
+**Harness:** same broker-down/broker-up harness as T7.4, plus a second
+consumer/producer pair for the `.dispatch` direction.
+
+**Integration test** — `tests/it_inbox_relay.rs`:
+1. Publish one message to `.dispatch`; assert exactly one run created via
+   the same `POST /v1/runs` path — instrument the API, assert the call, not
+   a direct kernel spawn.
+2. Force redelivery of the same message; assert still exactly one run
+   (T10.3's admission dedup catches it) — no relay-side special-casing
+   needed.
+3. Take the broker down; publish a message; bring the broker up; assert the
+   run is eventually created, no message lost.
+4. Publish a malformed message; assert it's dead-lettered, relay keeps
+   draining subsequent valid messages.
+5. Assert the relay never calls kernel spawn directly — instrument the
+   kernel's internal admission entrypoint, assert all calls originate from
+   the HTTP layer, none from relay threads.
+6. Assert inbox lag is emitted as a metric.
+
+**Command:** `cargo test -p distribution inbox_relay -- --test-threads=1`
+
+**False pass:**
+- Step 2 without step 1's exact-call-path instrumentation: a relay that
+  spawns directly and also happens to dedupe correctly would still pass a
+  coarser "one run" check while violating the no-bypass rule.
+- Skipping the malformed-message case: one bad message halting the whole
+  relay is a silent single point of failure discovered only in production.
+
+## Traps
+
+- Relay calling an in-process spawn function "for performance" instead of
+  going through `POST /v1/runs` — same trap T7.4 names for the outbound
+  side, mirrored here.
+- Building custom dedup logic in the relay instead of trusting T10.3's
+  admission-layer dedup. Two idempotency layers can disagree under partial
+  failure.

+
+## Goal
+
+Reference process that consumes `.events`, invokes the registered
+`Reconciler` for goal-tagged terminal transitions, and publishes decisions
+to `.dispatch` — never spawns a run itself.
+
+## Facts (inlined — no spec read needed)
+
+- The orchestrator embeds poimen only via the HTTP API (T10.4) /
+  `poimen-sdk`, exactly like any other external embedder — no special
+  kernel access.
+- Its entire job: consume `.events`, filter for goal-tagged
+  `Verified`/`Graded`/`Ungraded`, call `Reconciler` (T10.2), publish the
+  resulting `SpawnNext` decision to `.dispatch`. `Stop`/`Retry` decisions
+  are recorded but do not publish a dispatch message.
+- The default `Reconciler` implementation may itself be another poimen run
+  (a `Model` step + a `Tool` step) — the orchestrator's job is identical
+  regardless of whether the bound `Reconciler` is LLM-backed or a
+  hand-written Rust impl.
+- Never publishes a run directly, never calls `POST /v1/runs` itself — that
+  would reintroduce the bypass T10.7's inbox relay exists to prevent. Its
+  only write is to `.dispatch`.
+
+## Steps
+
+1. Consume `.events`, filter to records with a `GoalId` and a terminal run
+   state (`Verified`/`Graded`/`Ungraded`).
+2. For each, build `ReconcileCtx` (T10.2) and call the `Reconciler` bound to
+   that goal.
+3. On `SpawnNext`: publish `{workflow_ref, input, goal_id, dispatch_key}` to
+   `.dispatch` — `dispatch_key` derived from the decision id so redelivery
+   is naturally deduped downstream (T10.3).
+4. On `Retry`/`Stop`: record the decision (`WorkEvent` provenance per
+   T10.2), publish nothing.
+5. Own failure domain: separate process, own consumer group, own
+   retry/backoff on `Reconciler`-call failure — a `Reconciler` error does
+   not crash the orchestrator, it skips and retries on next poll or leaves
+   the goal stalled with a visible metric.
+6. Emit reconcile-latency and goal-stall metrics.
+7. Test the full loop against a stub `Reconciler`: events in, dispatch out,
+   verified end to end including a two-hop goal chain (run A → reconcile →
+   run B → reconcile → stop).
+
+## Acceptance
+
+- A two-run goal chain (A completes → reconcile → B spawns → B completes →
+  reconcile → `Stop`) completes end to end through real Kafka topics, with
+  the orchestrator never calling spawn directly.
+- `Reconciler` failure on one goal does not block reconciliation of other
+  goals.
+
+## Verify
+
+**Harness:** real Kafka (or the board's chosen fault-injection substrate),
+stub `Reconciler` with scripted decisions, T10.7's inbox relay running
+alongside.
+
+**Integration test** — `tests/it_orchestrator_e2e.rs`:
+1. Spawn run A with `goal_id=G`, no `dispatch_key`. Drive to
+   `Verified{pass}`.
+2. Assert orchestrator calls `Reconciler` exactly once for A; stub returns
+   `SpawnNext` for run B.
+3. Assert a message lands on `.dispatch`, and via T10.7's relay, run B is
+   spawned with `goal_id=G`.
+4. Drive run B to `Graded`. Assert `Reconciler` called again; stub returns
+   `Stop`.
+5. Assert no further `.dispatch` message is published; goal G's chain shows
+   exactly `[A, B]` via T10.1's `GoalView`.
+6. Instrument `POST /v1/runs`; assert zero calls originate from the
+   orchestrator process — only from the inbox relay.
+7. Second goal G2 with a `Reconciler` that always errors; assert G2 stalls
+   (visible via goal-stall metric) while G's chain, run concurrently,
+   proceeds unaffected.
+
+**Command:** `cargo test -p orchestration orchestrator_e2e -- --test-threads=1`
+
+**False pass:**
+- Step 6 omitted: an orchestrator that takes a shortcut and spawns directly
+  under test-only conditions would still pass steps 1-5.
+- Testing only a single-hop chain (A → `Stop`) — the two-hop case is what
+  proves goal-chain provenance actually threads through `GoalView`
+  correctly across a full reconcile-dispatch-relay-spawn cycle.
+
+## Traps
+
+- Orchestrator holding an admission-layer shortcut "to save a network hop."
+  Collapses the exact boundary T10.7 was built to enforce.
+- Coupling `Reconciler` failure handling to a single global retry policy.
+  One broken goal's `Reconciler` should not starve reconciliation for every
+  other goal in the tenant.

+# T10.9 — CLI: runs list/episode/transcript
+
+| Field | Value |
+|---|---|
+| Phase | P10 — Orchestration |
+| Size | S — under 1 day |
+| Status | Not started |
+| Flags | — |
+| Spec | inlined below |
+| Blocks | — |
+
+## Goal
+
+Three thin CLI wrappers over the HTTP API — `poimen runs list --goal <id>`,
+`poimen runs episode <run_id>`, `poimen runs transcript <run_id> <step>
+<attempt>` — the whole troubleshooting UX, no dashboard.
+
+## Facts (inlined — no spec read needed)
+
+- Thin HTTP clients, not a second implementation of the query logic already
+  in T10.1/T1.7/T1.6 — the CLI calls the same routes T10.4 exposes.
+- Rides the eventual shared `poimen` binary (T9.3); workable as a standalone
+  binary if T9.3 hasn't landed yet — soft dependency, not a hard block.
+- `episode` output must include failed attempts by default — T1.7's own
+  rule. A CLI that hides them defeats the purpose of the command.
+- `transcript` dereferences the `BlobRef` server-side, via the HTTP route
+  (T10.4) — the CLI never talks to `BlobStore` directly.
+
+## Steps
+
+1. `poimen runs list [--goal <id>] [--status <state>]` → `GET /v1/runs`,
+   table output (`run_id`, `status`, `goal_id`, age).
+2. `poimen runs episode <run_id>` → `GET /v1/runs/{id}/episode`,
+   human-readable rendering of `EpisodeView` including failed attempts,
+   clearly marked.
+3. `poimen runs transcript <run_id> <step> <attempt>` → `GET .../transcript`,
+   prints prompt/output text, dereferenced server-side.
+4. Exit codes: non-zero on API error, distinct code for "run not found" vs
+   "transport error" — operator scripting depends on this distinction.
+5. Test against a live embedded API instance (T10.4's test harness) with a
+   run that has a retry and a rewind.
+
+## Acceptance
+
+- `episode` on a run with two failed attempts and one success shows all
+  three, visually distinguishable.
+- `transcript` returns the same text content as reading the `BlobRef`
+  directly through `BlobStore` in a test assertion.
+
+## Verify
+
+**Harness:** T10.4's `axum` test instance, one run with a retry (two
+attempts, one failed) and a rewind.
+
+**Integration test** — `tests/it_cli_runs_ux.rs`:
+1. `runs list --goal G`; assert output contains exactly the runs tagged G,
+   none untagged.
+2. `runs episode <id>`; assert both the failed and successful attempt
+   appear — count them explicitly, not just non-empty output.
+3. `runs transcript <id> <step> 1` (the failed attempt) and `... 2` (the
+   retry); assert distinct content for each, matching their respective
+   `BlobRef`s byte-for-byte.
+4. Run-not-found case; assert a distinct exit code from a transport-down
+   case.
+
+**Command:** `cargo test -p cli runs_ux`
+
+**False pass:**
+- Step 2 checking only that output is non-empty — a CLI silently filtering
+  to the winning attempt (T1.7's own named trap) passes a non-empty check
+  while hiding exactly the debugging signal requested.
+
+## Traps
+
+- Filtering episode output to "just the successful attempt for clarity" —
+  T1.7's trap restated at the CLI layer; the failed attempts are the reason
+  this command exists.
+- Fetching transcripts client-side by resolving `BlobRef` directly instead
+  of through the HTTP route. Bypasses the tenant auth checks the API
+  enforces.
