Follow-up to HARNESS-WP-0001 (done) and glas-harness
`docs/adr/ADR-001-rein-harness-family.md`. This repo (formerly
agent-harness) is now the `rein-aharness` rein: the Claude-Code-CLI-driven
harness for governed, unattended/scheduled tenant work, consumed through
glas-harness's router once GLAS-WP-0001 lands. This workplan finishes the
rename and prepares the repo to be called *as* a rein rather than run
standalone.

## Task: Repo-identity rename (this session)

Local directory (`~/agent-harness` → `~/rein-aharness`), git remote
(`coulomb/agent-harness.git` → `coulomb/rein-aharness.git`, already
renamed on Forgejo by the operator), `pyproject.toml` `[project].name`,
and self-referencing prose in `README.md`/`INTENT.md`. Does **not**
touch the CLI command name, Python package name, or deploy artifacts —
see next task.

```

## Task: Deploy/package rename (deliberate follow-up, needs a maintenance window)

Rename the parts of this repo that a mechanical identity rename would
otherwise silently break, because they touch a *live* Railiance
deployment: the `agent-harness` CLI command, the `agent_harness` Python
package directory, the Docker image tag, the k8s namespace/labels/
ConfigMap names, the Railiance host directory, and
`deploy/scripts/railiance-smoke.sh`'s env var and paths.

**Code/config side done (2026-07-26):**
- `agent_harness/` → `rein_aharness/` (`git mv` + all internal imports)
- `pyproject.toml`: `[project.scripts]` → `rein-aharness =
  "rein_aharness.cli:main"`; wheel package name
- `Containerfile`: `COPY rein_aharness`, `ENTRYPOINT ["rein-aharness"]`
- `Makefile`: `IMAGE`/`TAR` → `rein-aharness:railiance01` /
  `rein-aharness-railiance01.tar`; `deploy-rsync` target path
- `deploy/k8s/railiance/*.yaml`: namespace/labels/names/image all
  `rein-aharness`
- `deploy/scripts/railiance-smoke.sh`: `AGENT_HARNESS_ROOT` →
  `REIN_AHARNESS_ROOT`, default checkout path, AppRole env source path
  (SSH host alias for Forgejo left untouched — that's an external
  `~/.ssh/config` entry, not owned by this repo)
- In-repo identity strings updated too: `hub.py`'s `source` field,
  `metrics.py`'s `harness` field default, `intake.py`'s
  `DEFAULT_ASSIGNEE`, `cli.py`'s `argparse` prog name, commit
  author identity in `smoke.py`/`tenant_onboard_runs.py`
- Verified: 47/47 tests pass, `rein-aharness` CLI runs correctly from a
  fresh venv, `docker build` succeeds and the built image runs
  (`ENTRYPOINT`/`CMD` dispatch correctly)
- `deploy/README.md` gained an explicit **rename cutover checklist**
  for the parts this session cannot safely do unattended: moving the
  host-side secrets dir (`~/.local/agent-harness` → `~/.local/rein-aharness`)
  and checkout (`~/agent-harness` → `~/rein-aharness`) on railiance01
  itself, and not deleting the old k8s namespace until the new one is
  confirmed working

**Live cutover done (2026-07-26), operator go-ahead:**
- Moved `~/.local/agent-harness` → `~/.local/rein-aharness` on
  railiance01; fixed two host-side references the rename checklist
  hadn't anticipated: the AppRole/PYTHONPATH paths inside `env` (plain
  `sed`, no secret values touched or viewed — the classifier correctly
  blocked a direct `cat` of that file, so all edits were blind, precise
  substring substitutions), and `~/.ssh/config`'s `Host
  forgejo-agent-harness` `IdentityFile`, which still pointed at the old
  secrets path (alias name itself left unchanged — it's just a label,
  and rein-aharness's own code references it by that exact name).
- `make deploy-rsync` to the renamed checkout path (old one was 8 days
  stale, fresh sync instead of `mv`).
- Rebuilt the host venv at the new path from scratch — a venv's shebang
  lines embed absolute paths, so renaming the directory alone breaks
  `pip`/the entry point; recreated with `python3 -m venv` +
  `pip install -e ~/rein-aharness -e ~/llm-connect`.
- `make image-export` → scp → `k3s ctr images import`, `kubectl apply -k`
  the renamed manifests (new `rein-aharness` namespace stood up
  alongside the old one, not overwriting it).
- Verified before touching anything old: `kubectl rollout status`
  succeeded, the in-cluster smoke Job completed, and the **authoritative
  host smoke script** passed fully (`ok: true, committed: true,
  pushed: true`, real commit to `executor-sandbox`, `harness_smoke`
  event confirmed in State Hub).
- Only then, with the operator's go-ahead: deleted the old
  `agent-harness` k8s namespace and removed the stale `~/agent-harness`
  checkout. No trace of the old name left on the host.

## Task: Implement the glas-harness rein contract

Once `glas-harness` GLAS-WP-0001-T01 defines the harness contract
(`start_session`/`dispatch_tool`/`end_session` or equivalent), adapt this
repo's `runner.py`/`adapter.py` to expose it, so glas-harness can call
into `rein-aharness` instead of `rein-aharness` only running itself via
its own CLI/poll loop.

**Coarse level live-proven (2026-07-26):** glas-harness's
`glas_harness/reins/rein_aharness.py` implements the contract by
shelling out to `agent-harness run --task-file ...` as one opaque
`dispatch_tool` call — proven live end-to-end (real `ext.bwrap`
sandbox, real `kaizen-agentic schedule prepare`, real `claude --print`
session, real verified commit in 11.4s).

**Per-tool-call audit added (2026-07-26), not full external dispatch —
that's structurally impossible for Claude Code's `--print` mode.**
Claude Code executes its own tools internally; there is no way for a
caller to externally decide/execute individual tool calls without
abandoning Claude Code's self-contained agent model. What *is*
possible: `claude --print --output-format stream-json
--include-hook-events` streams each tool_use/tool_result/hook event in
real time. Added:

- `adapter.py`: `AgenticClaudeCodeAdapter` gains an optional
  `on_tool_event` callback; when set, runs claude in streaming mode
  (`_execute_streaming`, `Popen` + background reader thread) instead of
  the blocking `subprocess.run` path (unchanged when no callback is
  given — zero behavior change for existing callers).
- `runner.py`: `run_task` gains `emit_tool_events`/`on_tool_event`
  params; each event is collected onto `RunResult.tool_events` and
  (when `report_to_hub`) posted as its own `tool_call` State Hub
  progress event.
- `cli.py`: new `--stream-tool-events` flag on `run`, prints each event
  as a tagged `{"stream_event": ...}` JSON line while running, ahead of
  the existing final result block (unchanged final output shape).
- glas-harness's `ReinAharness` gained a `stream_tool_events` flag;
  when set it passes `--stream-tool-events` and parses the tagged lines
  back out of captured stdout into `ToolResult.events` — real per-tool
  audit data, delivered after `dispatch_tool` returns rather than via a
  live callback (the `Rein` contract has no per-event hook; `dispatch_tool`
  is still one call in, one result out).

Live-verified against the real `claude` CLI (not mocked): 5 real
tool events streamed correctly (2× `Bash`, 1× `Write`) plus `Stop` hook
lifecycle events, real commit landed, final result block unchanged.
13 new tests in rein-aharness (`test_adapter.py` + 2 in
`test_runner.py`), 2 new tests in glas-harness (`test_rein_aharness.py`)
— all passing, all mocked except the one live CLI run above.

## Task: Decide scheduling/blueprint coupling boundary

Resolved in `glas-harness/docs/adr/ADR-003-scheduling-and-blueprint-sourcing-stay-rein-local.md`:
**stays rein-local.** With `rein-openweights` now real (not
hypothetical), the two reins already sit at opposite ends of this
question with no code change needed — `rein-aharness` keeps its
existing kaizen-agentic + issue-core coupling unchanged;
`rein-openweights` has none at all (task-file/caller-driven). glas-harness
does not become a task source or scheduler, consistent with its own
INTENT.md boundary ("Not a scheduler... activity-core" already listed
under "What it is not").
