Marius CiepluchandClaude Opus 5.5 f4bd984fda docs(harnessx-removal): the plane replaces HarnessX in README, docs and specs (task 8)
README: "Configuring the HarnessX agentic plane" becomes "The agentic
plane (ax)" (ousast plane run|status|doctor|remember, per-task Model,
budget and egress, pointer to ops/ax/README.md, one tagged retirement
line); "The HarnessX self-improving cycle" becomes "The self-improving
cycle", and its MetaAgent paragraph is replaced by the memory proposer
(`ousast improve --memory`, provenance, train-on-test guard). The fusion
panel_model/decider_model lines and the [harnessx] spend caps are gone.
The README reference test now passes without its strict xfail.

docs/examples.md section 6 runs the plane; docs/threat-model.md describes
the per-task EgressPolicy, the usd/calls budgets and the start-request
credential path. RELEASE_NOTES.md gets an Unreleased entry: HarnessX
removed, the retired keys and their errors, the silent loss of the
second hunter for users who set [models] hunter, and the plane as the
agentic path.

Dated retirement notes (2026-09-30) head the requirements, design and
brief of harnessx-self-improving-rulesets, learning-harness,
three-stage-scan and openrouter-sast-harness, and follow the spec table
in steering/overview.md; history is unchanged. All tasks are checked, so
spec.json moves to implementation-complete.

# Implementation Plan
Order follows the design's commit sequence (Requirement 5): nothing is deleted before its replacement has landed
and passed its fixture test. Every task is a commit gated on the full suite's own exit code, `ruff check`,
`ruff format --check` and `mypy`; the reconciler stays under 500 lines.
- [x] 1. Baseline without the extra
- Equality script (design §3) with its `find_spec("harnessx")` and freeze checks; re-sync `.venv` without the
`harnessx` extra first.
- Record `benchmarks/measurements/<date>-harnessx-removal-baseline/`: full suite, `ousast pairs --json`, the
`python-vulnerable` quick benchmark, one standard-mode scan, `ousast improve --dry-run`; the exclusion list
written next to it.
- _Requirements: 3.1, 5.1_
- [x] 2. Memory store and the `remember` task
- `plane/memory.py`: the `MemoryStore` interface with `FileStore` and `MinioStore` (object metadata/tags,
S3 Select JSON queries probed with a local fallback, versioned provenance, lifecycle, presign stubs;
`OUSAST_MEMORY` selects; MinIO settings from `.env`; `minio` SDK as an optional extra); JSON rows per
repository + pin, facts by content hash, `FileStore` ingest refuses below 1 GiB free,
`plane/tasks/remember.py` (model-free), `reconciler.mark_done` under the run lock, seed and ingest wiring in
`cli._plane`, generator annotations; fact reuse when repository, pin, candidate set and runner image match.
- Fixture tests: rows from a recorded Run, reuse on an unchanged pin, recompute on a changed one, disk refusal.
- _Requirements: 6.1, 6.4_
- [x] 3. Proposals from memory
- `improve/memory.py` with rules M1 (demote) and M2 (promote) and the advisory disputed-family signal;
`run_round(proposals=...)`; `ousast improve --memory` (opt-in; default output byte-identical); provenance per
proposal in the sidecar and journal; the train-on-test guard (qualification population, gated benchmark cases,
holdout pairs).
- Tests: each rule on crafted rows, the guard drops excluded rows, provenance round-trips, default `improve`
unchanged.
- _Requirements: 6.2, 6.4_
- [x] 4. The loop as a plane Run
- Tasks `alerts`, `measure`, `propose`, `improve` (no Model, zero budget); `--loop` Run generation; fixed-pin
Workspaces; the gate's verdict in `<run>/loop-improve/gate.json`; adoption stays a maintainer commit.
- Fixture tests with the fake ax; one live loop Run on the local ax recorded (no model spend beyond the verify
passes it reuses from memory).
- _Requirements: 6.3_
- [x] 5. Retire the HarnessX scan paths
- `cli.py`, `fusion.py`, `verify_judge.py`, `stage_processors.py` changes; `RetiredConfigError` for
`[models] verifier`, `[fusion] panel_model`/`decider_model`; one warning for a `[harnessx]` section (the only
tagged retirement text allowed in `src`, enforced by a test); tests renamed to the behaviour they assert.
- _Requirements: 1.1, 1.2, 1.3, 3.3_
- [x] 6. Delete HarnessX code and packaging
- Delete `harness_ext.py`, `hunter_harness.py`, `verify_judge.py`'s judge path, the HarnessX-only tests; remove
the extra, the mypy override and the `uv.lock` entry; rename the conftest fixture; audit rows and manifest; the
reference search test (Req 2.4).
- _Requirements: 2.1, 2.2, 2.3, 2.4_
- [x] 7. Equality proof
- Rerun the baseline script; commit the comparison record next to the baseline; any difference outside the
exclusion list blocks the merge.
- _Requirements: 3.2_
- [x] 8. Documentation and specs
- README ax-plane section pointing at `ops/ax/README.md`; `docs/examples.md` §6 and `docs/threat-model.md`
(egress policy, budgets); dated retirement notes in the four specs and `.kiro/steering/overview.md`; release
note naming the silent loss of the second hunter for users who set `[models] hunter`.
- _Requirements: 4.1, 4.2, 4.3_
