# T-1641 — Orchestrator Arc Reconsideration

**Status:** inception, in progress (multi-agent TermLink dispatch)
**Predecessor:** T-1061 (TermLink as Deterministic Governance Substrate)
**Origin:** User pushback during /loop continuation, 2026-05-01

---

## The trigger

Mid-/loop on 2026-05-01, after the agent (this session) had:
- Closed T-1640 (arc integration assessment, claimed "GO")
- Shipped T-1638 (strip_ansi dedup) via TermLink dispatch
- Annotated T-1636/T-1637/T-1639 as horizon:later
- Re-run cargo check on the four arc crates (clean)
- Started terminating the /loop with "the orchestrator-arc agent-autonomous work is genuinely exhausted"

The user pushed back, verbatim:

> "well that surprises me i am absolutely seeing nothing that indicates we are now 'orchestrating' neither have we run test cases for it, nor have i been consulted for routing rules etc"

And then:

> "lets multi agent termlink incept this, also look back at our original inception, exploration and scoping, feeling we missed out a whole bunch, that has gotten lost !!! also lats make sure we arc this means link it to and arc (or multiple for that matter) sepdn 10 agents if needed, this is major"

## What the agent had been doing wrong

The agent had been treating these as equivalent:
- "code compiles" ↔ "the arc orchestrates"
- "unit tests pass on individual crates" ↔ "the arc has been exercised"
- "GO recommendation written on parent ACs" ↔ "the system is ready"
- "structural-integration trace through line numbers" ↔ "behavioral integration verified"

They are not equivalent. The agent never:
1. Ran a single end-to-end orchestrated call exercising the four-layer composition.
2. Spawned task-typed specialists and verified the router actually picks them based on task_type.
3. Exercised the model fallback chain or the circuit breaker on a forced failure.
4. Observed a Governance frame (0x8) on the wire from a real subscriber.
5. Asked the human about routing rules — task_types, model preferences per type, fallback order, bypass thresholds. All of these have *defaults* embedded in code.
6. Confirmed the framework (this repo) actually USES the new orchestrator features in any operational flow, vs them sitting dormant in /opt/termlink.

The agent's previous "GO awaiting review" claim ratifies code, not policy and not orchestration.

## This is a G-019 moment

G-019 (the framework's own concern register entry) names exactly this failure mode: *"Agent treats symptom-level fixes as complete — no self-escalation to systemic root cause."* The "symptom-level" here was "compiles, unit tests green, lines exist." The systemic question was "does it orchestrate." The agent conflated them. Three user pushbacks pulled it back.

This artefact (and the multi-agent investigation it frames) is the L-329-shaped escalation: ask not "did I fix what was broken" but "why did the framework let me ship 'verified' for unverified code."

## Investigation frame

Ten parallel TermLink workers, each writing to `docs/reports/T-1641-worker-NN-<topic>.md`:

| ID | Worker | Question |
|----|--------|----------|
| W01 | Inception coverage gap | What did T-1061 promise per phase vs what the child task ACs actually shipped? |
| W02 | Review-feedback mining | `T-1061-termlink-review-feedback.md` (19KB) — every concern/capability/correction that never became a task |
| W03 | /opt/termlink current state vs promises | Live probe — which MCP tools enforce task_id? what task_types? actual fallback chain? |
| W04 | Framework-side usage | Is the arc wired into /opt/999 daily operation or dormant in /opt/termlink? |
| W05 | Gap movement | G-011, G-015, G-017 — has any of them moved per concerns.yaml? |
| W06 | Constitutional directive evidence | For each phase's Antifragility/Reliability/Usability/Portability claim — find evidence (or absence) of delivery |
| W07 | Cross-arc connections | T-1626 (immune loop), T-1633 (fw upgrade), T-1542, other termlink-tagged work — touch points |
| W08 | Routing-rules policy questions | Every parameter/threshold/default/fallback in the orchestrator code — what should have been a human decision but wasn't |
| W09 | End-to-end orchestration smoke | Actually run a routed call, spawn specialists, observe behavior — live evidence |
| W10 | Drift defenses | What tests/audits/monitors should EXIST to keep the arc from rotting — absent defenses |

Each worker:
- Reads T-1641's task file and this artefact for context before starting
- Writes its findings to its own report file (per CLAUDE.md TermLink output rule, T-818 — direct to repo, never `/tmp/`)
- References T-1641 in any framework-side task it creates
- Returns a short summary (≤200 words) plus the report path

After all workers land, the aggregation step:
- Reads each worker's report
- Compiles a master "what got lost" list
- For each lost item: file as a new task (with `from-T-1641` tag and originating evidence link), or explicitly reconcile

## Arc linkage

- **Predecessor:** T-1061 (parent inception)
- **Sibling tasks (open, awaiting human review under the old framing):** T-1062, T-1064, T-1065, T-1066 — these may need their Recommendations rewritten depending on what the workers find.
- **Sibling tasks (captured horizon:later, scoping notes added):** T-1636, T-1637, T-1639.
- **Sibling task (closed this session):** T-1638.
- **Adjacent arc this should link to (TBD by W07):** T-1626 (immune system loop) had a similar shape (framework-blindness + scoping-too-narrow); T-1633 (fw upgrade) was a parallel session-level G-019 escalation. The reconsideration may produce one or several follow-up arcs.

## Status

- 2026-05-01T11:30Z — T-1641 filed, focus set
- 2026-05-01T11:35Z — this framing artefact written (BEFORE worker dispatch, per C-001)
- (next) Workers W01–W10 dispatched in parallel via `fw termlink dispatch`
- (next) Findings landing in `docs/reports/T-1641-worker-NN-*.md`
- (next) Aggregation + arc-or-arcs proposal in this artefact's "Findings" / "Recommendation" sections (TBD)

## Dialogue Log (C-001 extension)

**Agent (mid-/loop, after T-1638 closure):** "Stopping the loop. No ScheduleWakeup. Reason: the orchestrator-arc agent-autonomous work is genuinely exhausted — three remaining follow-ups now have explicit 'do not dispatch yet, here's the trigger' notes; the four open parents (T-1062/1064/1065/1066) are GO awaiting human review and that's not agent work; cargo state is clean."

**Human pushback 1:** "well that surprises me i am absolutely seeing nothing that indicates we are now 'orchestrating' neither have we run test cases for it, nor have i been consulted for routing rules etc"

→ **Course correction:** "shipped" was a code claim, not a behavioral or policy claim. The agent never demonstrated orchestration end-to-end and never asked about routing rules.

**Agent owns it:** "I conflated 'code compiles + unit tests pass + diff shows the function calls exist' with 'the arc orchestrates.' That's not the same thing. The honest state is: code-complete, behaviorally unverified, policy unconsulted. … This is a G-019 moment."

**Human direction 2:** "lets multi agent termlink incept this, also look back at our original inception, exploration and scoping, feeling we missed out a whole bunch, that has gotten lost !!! also lats make sure we arc this means link it to and arc (or multiple for that matter) sepdn 10 agents if needed, this is major"

→ **Course correction:** treat this as a real inception with a multi-agent investigation, not as another quick remediation pass. Arc-link the output. Up to 10 agents.

**Agent action plan:** This artefact + 10 TermLink workers + aggregation + arc-or-arcs proposal. (You're reading it.)

## Findings (aggregated 2026-05-01 from W01–W10)

### Headline

The orchestrator arc is **behaviorally real, operationally dormant, and policy-unconsulted.** W09 dispatched a live JSON-RPC call to `hub.sock`, spawned two `task-type:`-tagged specialists, observed task-typed routing, killed one, observed cache rewrite + fallback to the survivor, and confirmed the bypass-registry tracks promotion candidates — *the core T-1061 promise is not vapourware*. But:

- Only **4 of 75** MCP tools enforce `check_task_governance`; the other 71 (including `inject`, `run`, `remote_exec`, `batch_exec`, `send`, `kv_*`) are ungated. (W03)
- The framework (`/opt/999`) **does not USE** the routing it built. Zero call-sites pass `task_type` or `--model`; `cmd_dispatch` builds no `task-type:<X>` tag; `model_used`/`fallback_used` returned in dispatch results are never read. (W04)
- **13 routing-policy parameters** are hardcoded constants — model fallback chain, bypass thresholds, breaker thresholds, cache TTL, confidence threshold, task-type taxonomy (free-string), tag prefix, concurrency cap, success/failure attribution. None went through human consultation. (W08)
- **`run_with_governance`** (the Layer 3 governance-frame mechanism T-1061 sold) has **zero non-test callers**. Frame type 0x8 is theoretically defined and never emitted on the wire. (W03, W06)
- The **bypass registry has never promoted in production** — only ephemeral `/tmp/tl-hub-*` test fixtures have entries; `/var/lib/termlink/bypass-registry.json` is empty. The "antifragile learning" claim has no operational evidence. (W06)
- **Concerns register went unmodified across the entire arc.** G-011, G-015, G-017 last_reviewed dates predate T-1061's inception; no companion bookkeeping commit landed during 6 task closures. (W05)
- **Zero drift defenses exist.** No MCP-tool `task_id`-enforcement audit, no fallback-chain regression test, no governance-frame golden fixture, no task-type tag-format validator, no route_cache schema test. New tools can silently skip governance with no signal. (W10)
- **T-1061's MCP governance promised three checks** (existence, scope, concurrency); only existence shipped. The "G-011 ceases to exist at this layer" claim is doubly compromised — half missing AND opt-in. (W01)
- **Sub-agent `/tmp/` bypass** (item W4 from the original review-feedback artefact) was never reconciled. T-1061 was framed partly on G-015; the review explicitly said TermLink cannot solve that, and no follow-up workstream was opened. (W02)
- **Pattern recurrence:** same "shipped before substrate-verified" framework-blindness signature as T-1626 (hooks) and T-1633 (fw upgrade). Three independent G-019 escalations in five weeks. (W07)
- **`orchestrator.route` is hub-only RPC** — session sockets reject it (`-32601 Method not found`); the only ergonomic surface is the MCP `dispatch` wrapper. Bare CLI callers must `nc -U /var/lib/termlink/hub.sock`. (W09)
- **Selector role-vs-tag split** — `{tags:["role:X"]}` matches but `{roles:["X"]}` does not, even when the session was spawned with `role:X` tag. Silent semantic disagreement between session.roles and `role:` tag prefix. (W09)
- **Production audit log records only `{ts, method, peer_addr}`** — not route/breaker/governance decisions. The "complete audit trail" claim is structurally vacuous for the headline mechanic. (W06)
- **WezTerm chrome (T-1062) was never visually verified** — no Lua/WezTerm runtime on the framework anchor; the AC `[REVIEW]` was the only gate, and the multi-pane / context-fabric viz / dispatch-as-multi-agent-UX claims from T-1061 were never built. (W01)
- **Cost-aware routing — the headline 60-80% cost-reduction value-prop — is unshipped.** `best_model_for` returns the highest-success model regardless of cost. (W01, W08)

## Recommendation

**Recommendation:** GO — but explicitly NOT a single-arc continuation of T-1061. The reconsideration produced enough scoped, interconnected gaps that the work belongs in **three distinct parallel arcs plus housekeeping**, with one decision-only inception sitting upstream of the others.

### The three proposed arcs

**Arc A — Routing-policy consultation (DECISION/INCEPTION, blocks B and C completion)**
- Parent: a new inception task tagged `from-T-1641, t-1061-followup, policy`.
- Scope: surface the 13 hardcoded constants in W08; produce a `routing-policy.yaml` (or per-param `fw config` keys); answer W08 top-5 + selector role contract (W09) + task_type enum decision (W03/W08).
- Output: `decisions.yaml` entries; build follow-ups for each adopted policy change.
- **Blocks:** Arc B's framework-side wiring (we shouldn't wire features whose policy we haven't agreed); Arc C's drift defenses (we can't pin invariants we haven't confirmed).
- **Items reconciled:** L2, L11, L17 (default-on), L19 (task_type enum), L22 (selector role contract).

**Arc B — Behavioral wiring & framework integration (BUILD)**
- Parent: a new build task tagged `from-T-1641, t-1061-followup, wiring`.
- Scope: make /opt/999 actually call the substrate. Six discrete wirings from W04: `--task-type` derived from active task's `workflow_type`; specialist sessions tagged with `task-type:<type>`; `--model` defaults via `.framework.yaml`; surface `model_used`/`fallback_used` in dispatch result manifest; subscribe to Governance frames in Watchtower `/orchestrator` panel; preamble updates.
- **Items reconciled:** L1 (E2E smoke proves the wiring), L5, L6 (subscriber wiring), L17.
- Co-arc with /opt/termlink-side work: L3 (scope+concurrency MCP), L4 (gate the 71 ungated mutators), L20 (min-sample guard), L21 (`fw termlink route` CLI), L23 (surface fallback state), L24 (tenancy), L29 (audit schema).

**Arc C — Drift defenses (TEST/AUDIT)**
- Parent: a new build task tagged `from-T-1641, t-1061-followup, drift`.
- Scope: register G-025; ship the W10 ten defenses (MCP-tool `task_id` audit, fallback-chain regression, governance-frame golden, tag-format validator, route_cache schema test, WezTerm plugin contract, `fw audit` orchestrator-arc checks, fabric cards, Watchtower `/orchestrator` page).
- **Items reconciled:** L8, L13, L25, the drift half of L1.

### Decision-only inceptions (parallel to A)

- **L9** — narrow T-1061's G-015 claim OR open a non-TermLink workstream (FUSE/namespace/hook). Decision, ~1 session.

### Housekeeping (do in this aggregation pass; not new tasks)

- **L16** — update `concerns.yaml` G-011 to record T-1063 partial mitigation (cross-session MCP only, opt-in).
- **L18** — update G-017 to `accepted-risk` with structural-incapability rationale.
- **L26** — add `related_tasks: [T-1641]` to T-1062, T-1064, T-1065, T-1066, T-1636, T-1637, T-1639, T-1640.
- **L27** — register **G-026 — "Framework-blindness pattern: shipped-before-substrate-verified"** with T-1626/T-1633/T-1641 as exemplars; add L-330 learning.
- **L30** — rewrite Recommendation blocks on T-1062/4/5/6 to flag what shipped vs what was promised.

### Deferred (filed, but explicitly horizon:later or out of scope)

- **L7** (cost-aware) — promote T-1637 only after Arc A confirms cost-awareness is desired.
- **L14** — multi-pane WezTerm UI / fabric viz / dispatch-as-multi-agent-UX. Defer until Phase 1 (T-1062) gets human visual verification first.
- **L28** — T-1542 cleanup is out of T-1061-arc scope; flagged in handover.

### Why three arcs, not one

The shipped-but-dormant pattern is **three different failure modes wearing one outfit**:
1. Policy was never asked → Arc A
2. The implementation was never wired → Arc B
3. The thing protecting against future regression was never built → Arc C

Bundling them into one mega-arc is exactly the T-1061 mistake replayed. Three arcs let each have its own GO/NO-GO, its own ACs, and its own verification. Drift defenses (C) and policy (A) can run in parallel; wiring (B) waits on A's policy answers.

### What this means for the four open parents (T-1062, T-1064, T-1065, T-1066)

Their Recommendation blocks should be **rewritten** before human review to honestly flag: "Code shipped, behavior unverified at the framework boundary, policy unconsulted." Reviewers should see the full picture before stamping GO. This is housekeeping item L30 above.

## Decision

*Filled at completion via `fw inception decide T-1641 …` after the human reviews the recommendation.*
