+# Orchestra
+
+A Go implementation of `orchestra-spec (1).md` — an unattended multi-agent
+task orchestrator that leases coding tasks to CLI harnesses (Claude Code,
+Codex, opencode) running inside `herdr`-managed panes, rotates them across
+context-window limits, and hands off work via a git-anchored continuity
+protocol.
+
+Layout: `internal/{domain,store,provider,registry,router,herdr,orchestrator,
+continuity,federation,delivery,authz,operations,admin}` + `cmd/orchestra/main.go`.
+
+## Ground truth over documentation
+
+This repo has a documented history of code that *looks* wired but isn't —
+packages with tests that pass in isolation while the live call path silently
+no-ops (bare `continue` on error, discarded return values). See `AUDIT.md`
+for the full audit and `progress.md` for a running log. **Before trusting a
+claim in progress.md that something "works" or "is fixed," check the actual
+call site** — the file is written by past sessions of this same assistant and
+has previously overstated completion.
+
+The single most reliable way to verify herdr-adapter code is right: don't
+read `internal/herdr/adapter.go` and assume the method names are real. Ping
+the live herdr instance and check.
+
+## herdr protocol — verified against a live instance, 2026-07-27
+
+- herdr speaks JSON-RPC over a raw TCP (or unix-socket) connection — **not
+  HTTP**. `internal/herdr/herdr.go`'s `Client.Call` is the only correct way
+  to talk to it; a bare `curl` to the port returns nothing.
+- Request shape: `{"id":"<n>","method":"<name>","params":<object>}`. Herdr's
+  Rust JSON-RPC decoder requires `params` to be present and rejects a bare
+  `null` — always send `{}` for parameterless calls (the client does this
+  automatically).
+- Full real method list is committed at `deploy/herdr-schema.json`, captured
+  live from `192.168.1.105:9245` (the `workpc` herdr) since no local `herdr`
+  CLI is available in this sandbox — the schema was reconstructed by sending
+  an unknown method name and reading the `unknown variant ... expected one
+  of ...` error, then probing each method of interest with `params:{}` /
+  `params:{pane_id:"nonexistent"}` to read Rust serde's `missing field
+  <x>` errors for its param shape.
+- **Confirmed invented (do not use, they don't exist):** `pane.release`,
+  `pane.kill`, `pane.rotation_signal`, `pane.status`. If you see these
+  anywhere, it's a bug, not a valid call.
+- **Real replacements:** `pane.close({pane_id})` for kill;
+  `pane.release_agent({pane_id, source, agent})` for release (structurally
+  different — does *not* return a `handoff_ref`, see below). No replacement
+  exists for `rotation_signal` — herdr has no concept of Orchestra rotation.
+- **Architectural point that's easy to get wrong:** herdr never produces a
+  handoff. The agent writes the handoff artifact (§6.1 of the spec); herdr's
+  role in "release" is only to drop its own claim on the pane/agent binding.
+  Any adapter code that expects herdr to hand back a `handoff_ref` is wrong
+  by construction, independent of whether the method name is right.
+- Protocol version is returned as a **JSON number** (`17`), not a string,
+  even though `config.jsonc` declares `"protocol": "17"` as a string.
+  `CheckProtocol`'s raw-bytes fallback happens to make this compare correctly
+  today — don't "clean up" that code without checking this note first, or it
+  might start doing a real numeric-vs-string comparison and break.
+
+## Deployment topology (as of 2026-07-27)
+
+- Runs as `orchestra.service` on **homesrv** (this machine's own systemd —
+  `journalctl -u orchestra.service` for logs; `sudo` isn't available in this
+  sandbox environment, but plain `journalctl` without sudo works here).
+- Config: `.orchestra-config/orchestra.env` (env vars) +
+  `.orchestra-config/config.jsonc` (projects/machines/herdrs registry).
+  `ORCHESTRA_CONFIG=/etc/orchestra/config.jsonc` — the deployed copy, not the
+  repo's `deploy/config.example.jsonc`.
+- Two machines in the registry: `homesrv` (192.168.1.104) and `workpc`
+  (192.168.1.105), each nominally running 3 herdrs (claude/codex/opencode).
+  In practice **homesrv has no local herdr running** (connection refused on
+  9245) — only workpc's herdr is live and reachable. `main.go` only logs
+  herdr connection *failures* at startup, never successes, so "no log line"
+  for a herdr does not mean it's down — check reachability directly.
+- There was a real, live, stuck task as of 2026-07-27: workspace `wA`, task
+  id `06FT6CKD9Y98AZRX6X8K3QXFZG`, opencode harness, pane `wA:p1`,
+  `agent_status: "blocked"`. Likely stuck because rotation/release could
+  never reach it (B2/B5). Check whether it's still stuck before assuming
+  fixes here have taken effect operationally — code fixes don't retroactively
+  unstick an already-orphaned pane; that needs a manual kill/restart once the
+  release path is trustworthy.
+
+## The federation fork — read before touching anything cross-machine
+
+Two incompatible designs coexist. **Design A** ("drive the remote socket",
+currently deployed via `clients/herdr-bridge.go`) has homesrv call
+`worktree.create`/`agent.start` etc. directly on workpc's herdr over TCP as
+if it were local — meaning anchor validation (`git rev-parse HEAD`) run by
+the coordinator executes on the *wrong machine* relative to the actual
+checkout. **Design B** ("workers pull tasks", `/v1/federation/*`) is fully
+built server-side but has zero clients — no worker binary exists. Decision
+(AUDIT.md, 2026-07-27): keep Design A through Phase 5, commit to Design B in
+Phase 6, with two guardrails landed immediately (refuse to rotate/cleanup a
+lease held by a non-local herdr rather than validate against the wrong
+checkout). Don't build on top of Design A's cross-machine calls without
+reading that section first.
+
+## Working conventions
+
+- `go build ./...`, `go vet ./...`, and `go test ./...` must all pass — `go
+  vet` was broken for a while (duplicate JSON struct tags) and nobody
+  noticed because only `build`/`test` were being checked. Always run all
+  three.
+- Silent `continue`-on-error is the recurring bug pattern in this codebase
+  (adapter lookups, rotation, expiry). When touching `internal/orchestrator`
+  or `internal/herdr`, prefer a recorded/observable failure
+  (`MonitorHealth` fields) over a bare `continue` — that's literally what
+  turned B1/B2 invisible for as long as they were.
+- Don't invoke destructive herdr calls (`pane.close`, `pane.release_agent`)
+  against a real pane from an investigative/audit session without asking
+  first — there is live operator state on the other end (see the stuck-task
+  note above).

+
+---
+
+## Phase 0 — done, 2026-07-27
+
+B1, B2, B4, B8, S1, S5, S6 were already fixed and landed as of this session
+(confirmed by reading the current code, not just trusting progress.md — see
+`adapterFor` in `internal/orchestrator/orchestrator.go:190` and
+`CLIAdapter.Occupancy` in `internal/herdr/adapter.go:197`).
+
+This box (homesrv) turned out to have live TCP reachability to the real herdr
+instance at `192.168.1.105:9245` (workpc) the whole time — the `unavailable:
+connection refused` lines in `journalctl -u orchestra.service` are for
+`homesrv-*` herdrs dialing `192.168.1.104:9245`, which has no local herdr
+running; `workpc-*` herdrs were connecting fine but main.go never logs a
+success, only a failure, so there was no positive signal either way. Also
+found: **a real task is stuck live right now** — workspace `wA`, task
+`06FT6CKD9Y98AZRX6X8K3QXFZG`, opencode agent, pane `wA:p1`, `agent_status:
+"blocked"` — almost certainly stuck because `Release`/rotation could never
+reach it (see below).
+
+Ran the actual Phase 0 steps against this live instance (raw JSON-RPC probes
+over TCP, params-omitted/empty-object tricks to read Rust serde's
+missing-field errors — no `herdr` CLI available locally, so `herdr api schema
+--json` itself wasn't run, but the equivalent info was extracted this way).
+Full method list and findings committed to `deploy/herdr-schema.json`.
+
+**Confirmed, with a real server response, not just static reading of
+adapter.go:**
+- `pane.release`, `pane.kill`, `pane.rotation_signal` — **none of these exist**
+  in the real protocol. Confirms B5's suspicion exactly.
+- Real replacement for `pane.kill` is `pane.close({pane_id})` — same shape,
+  drop-in. **Fixed** in `internal/herdr/adapter.go`.
+- Real replacement for `pane.release` is `pane.release_agent({pane_id,
+  source, agent})` — structurally different, and per B5's own analysis it
+  cannot return a `handoff_ref` regardless (herdr doesn't write handoffs, the
+  agent does, §6.1). Wiring this for real needs Phase 4's handoff-production
+  path first. `CLIAdapter.Release` now returns a loud error naming exactly
+  that instead of calling a method that doesn't exist. **Not a full fix** —
+  Phase 4 still owns making Release do something real.
+- `pane.rotation_signal` doesn't exist and never will (herdr has no rotation
+  concept) — deleted `RotationSignal` interface, its `CLIAdapter` method, and
+  the call site in `Coordinator.rotate`, per this doc's own instruction
+  ("Delete ... unless the schema proves it exists").
+- `agent.get`, `pane.read`, `agent.prompt`, `worktree.create`, `worktree.open`,
+  `agent.start` — all confirmed real, no changes needed there.
+- Protocol version confirmed live: `17`, matching `config.jsonc`'s
+  `"protocol": "17"` (returned as a bare JSON number by the server; the
+  existing string-fallback parse in `CheckProtocol` happens to handle that
+  correctly already).
+
+`go build ./...`, `go vet ./...`, `go test ./...` all pass after these
+changes.
+
+**Still open from B5** (not attempted this pass — larger, needs design, not
+just a method-name swap):
+- `agent.prompt` inline `wait` on `CLIAdapter.Lease` (still `wait=0`, per B5's
+  note that only `Bootstrap` passes a real wait).
+- `Release`'s real implementation, which depends on Phase 4 (§6) handoff
+  production existing at all.
+- The stuck live task (`06FT6CKD9Y98AZRX6X8K3QXFZG`) was deliberately **not**
+  manipulated directly (no `pane.close`/`pane.release_agent` call against it)
+  — killing or releasing a real running agent from an audit session without
+  the user present is exactly the kind of action that warrants asking first.

+**Phase 0 done (2026-07-27):** this box has live TCP reachability to the real
+herdr instance at `192.168.1.105:9245` — verified by hand (raw JSON-RPC
+probes, no `herdr` CLI available locally). Real method list captured in
+`deploy/herdr-schema.json`. Confirmed `pane.release`/`pane.kill`/
+`pane.rotation_signal` are invented, as AUDIT.md's B5 suspected.
+`pane.kill`→`pane.close` fixed as a drop-in. `pane.rotation_signal`/
+`RotationSignal` deleted (no replacement exists). `Release` now refuses
+loudly instead of calling a nonexistent method — its real implementation
+needs Phase 4 (handoff production) first, since even the real
+`pane.release_agent` can't return a `handoff_ref` (herdr doesn't write
+handoffs, the agent does). See AUDIT.md's new "Phase 0 — done" section for
+full detail. **Also found: a real task is currently stuck live** — workspace
+`wA`, task `06FT6CKD9Y98AZRX6X8K3QXFZG`, opencode, pane `wA:p1`, blocked —
+deliberately not touched from this session.
