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.

Reran benchmarks/harnessx_removal_equality.py record from a git archive
export of b9afb66 (tasks 1-6 landed; same venv freeze hash as the
baseline, harnessx not importable, no API keys, empty config) and
compared it against 2026-09-30-harnessx-removal-baseline:
equal=True differences=0
All 13 output files (pairs.json, benchmark, standard scan, improve
--dry-run) are raw-byte identical to the baseline. The suite map
(suite-map.json) accounts for 29 deleted ids, 2 renamed ids and 83
added ids; each deleted or renamed id cites the design's Tests table and
commit cbadc38 or b9afb66. Every surviving test id keeps its outcome
(1740 passed, 38 skipped incl. the README xfail).
Instrument note: a first record failed test_push_hook twice because the
recording shell's PATH lacked .venv/bin (the hook execs `ousast`); the
same two tests fail at b9afb66 without it and pass with it. The
committed record has .venv/bin on PATH.

Deletes harness_ext.py and hunter_harness.py with their HarnessX-only
tests (the judge path, verify_judge.py, went in task 5). The harnessx
extra, its mypy override and its uv.lock entries are removed (uv lock
drops only packages; no remaining version changes). The conftest
fixture becomes assert_cold_import; test_gate's two never-import checks
become one allow-list (stdlib, openultrasast, yaml) over the governance
planes' module-level imports, and the skipped live-extra tolerance test
is deleted. Audit rows for the two modules are removed, stage_processors
is reworded, and the module-audit manifest is regenerated (no orphan).
test_removed_plane_references implements Req 2.4 over src, tests and
pyproject.toml: a match must carry a `retired 2026-..` tag (the spec's
own slug is not counted). The README part is a strict xfail until task 8
rewrites the README's plane sections.

The standard scan now runs run_hunter_pool, verify_findings and the
deterministic fuse_findings directly; the HarnessX hunter orchestrator,
the LLM judge dispatcher (verify_judge.py, deleted with its test) and the
LLM fusion panels are gone, and so are their extra-absent degradations.
host_under_harnessx is dropped from stage_processors.
config: [models] verifier and [fusion] panel_model/decider_model raise
RetiredConfigError naming the plane replacement (the CLI prints it and
exits 2); a [harnessx] section loads with one warning and is otherwise
ignored. harness.json keeps "verifier": null. Tests that asserted the
fallback are renamed to the behaviour they assert; the module-audit
manifest drops verify_judge. Nothing outside the two modules deleted in
task 6 imports harness_ext or hunter_harness.

`ousast plane workspaces --validation-set ... --loop` appends the loop to a Run:
per case `alerts` (plane/tasks/alerts.py: the quick-mode scan on the vulnerable
and the fixed pin, a fixed-pin Workspace per case, alerts attributed to their
enclosing function by the repo-facts patterns, `in_fix_range` from the fix's
old-side and new-side ranges, failing on an unread tree) feeding `remember`,
then `memory-snapshot` -> `loop-measure` -> `loop-propose` -> `loop-improve`
(plane/tasks/loop.py). Every new task binds no Model and has budget
{usd: 0, calls: 0}. The snapshot is the store's rows after the train-on-test
guard, written on the host by memory.seed (a sandboxed run of it fails loudly);
propose runs M1/M2 against this repository at the commit under test; improve
runs one unchanged evolve.run_round and delivers gate.json, journal.json, the
sidecar, rule_policy.json only when accepted, and proposal_outcome rows that
the host ingests. Adoption stays a maintainer commit.
`remember` is now a Run entry per case (the image contains it), with the facts
row keyed by the image the facts were computed on (repo-facts records it in
its summary; unknown -> the row is omitted, never guessed). Alert rows carry
their own pin; improve/memory.py counts a repeated alert once.
Runner image rebuilt (+0.39 MB: only the new modules; the quick scan needs no
extra and the rulesets were already in the package), pushed, plane/ re-pinned
and regenerated (validation-46: 105 entries). Fixture test runs the whole loop
graph through the fake ax, whose new `exec` mode runs the real task modules.
Live: one loop Run over three validation-46 cases on the local ax, recorded in
benchmarks/measurements/2026-09-30-harnessx-removal-loop/ (all done, $0 new
spend, 0 proposals, gate verdict no_proposals).

improve/memory.py: rules M1 (enabled->shadow on repeated false alerts across
>=2 repositories, no agreed or site_match hit) and M2 (shadow->enabled on
>=2 agreed declared sites no enabled rule catches); M3 disputed families are
advisory (signals.json) and never reach the validator. The train-on-test
guard drops rows of --qualify-population, gated benchmark cases and holdout
pair repositories before any rule sees a row. run_round(proposals=...) adds
memory edits after the benchmark's through the unchanged validator and gate;
provenance (row ids, object keys and versions, counts, exclusions, index
digest) goes to memory_proposals.jsonl and the journal's evidence field;
proposal_outcome rows are written back after a non-dry run.

The design revisit after plane-increment-1.json (14/20 agreed, 19/20 in either
pass): a third verify pass on the candidates passes a and b dispute, and agree
decides 2-of-3 where pass c asked (the a/b rule elsewhere; c alone never decides).
- verify: optional OUSAST_INPUT_ONLY restricts the hunt to the named candidates
(agree's disputed.json); an empty list is done with 0 units and no model client.
- agree: optional OUSAST_INPUT_PASS_C; metrics keep every key and add tiebreak
{asked, flipped_to_agreed, flipped_to_rejected, rule}; usd_total, hunts and
declared-site metrics are on the final decision.
- generate: per case <case>-vc and <case>-final appended to validation-46; the
first 60 entries stay byte-identical, so a rerun keeps their done state.
- Offline replay over the recorded outputs with an empty pass c reproduces the
recorded agree summaries exactly (14/20 agreed, 23 agreed, 10 disputed).

A producer's artifact rendered as spec.files of a generated <task>-inputs
Workspace ends up in ax's AX_WORKSPACES_YAML env value; Agent Substrate
rejects values over 32768 characters, so a 182 KB facts.json broke ax apply
on the live cluster. The reconciler now passes OUSAST_INPUTS instead, the
receiver serves a running task its declared inputs over GET /inputs/..., and
the runner fetches them after the start (failed fetch -> failed summary).

The end-to-end smoke Run finished done on the local ax: submit, egress policy,
resume, router start, repo-facts in gVisor, artifacts delivered through the
egress gateway, attribution table printed, task and policy cleaned up.

Claude-Session: https://claude.ai/code/session_01EmM1j46qgKMh3zqD1QMwEo
Agent Substrate's egress gateway denies an actor without an EgressPolicy, so
no task could deliver its artifacts or reach a model. egress.py grants each
task exactly: http/80 to ousast-receiver.ax-system.svc.cluster.local, and
TLS passthrough/443 to the bound Workspaces' https Git hosts and the bound
Model's openultrasast.io/egress-hosts (api.deepseek.com for deepseek-flash).
No IPs, no wildcards, no https (MITM) rules.
The reconciler writes the policy with kubectl-ate between ax apply and
resume, reads it back, waits OUSAST_EGRESS_SETTLE (11 s, the gateway's
cached deny), and after ax delete task confirms the policy went with its
actor (kubectl-ate has no delete verb; the store cascades).
The receiver is a selector-less Service (ops/ax/receiver-service.yaml.tmpl,
applied by up.sh together with the no-build agentgateway egress gateway)
on port 18090 of the host. Measured live: the gateway checks the policy on
Host but connects to the address the actor dialled, so the runner dials the
Service's ClusterIP (OUSAST_ARTIFACT_DIAL) with the receiver's name as Host.
The runner now labels its delivery with the Run's task name (OUSAST_TASK),
which is what the receiver accepts; the ax Task name was refused with 403.
The Receiver moved to egress.py to keep reconciler.py at 460 lines.

agree matched declared sites through benchmarks/independent/evaluate.py,
which the runner image does not carry, so site matching would have been
"not assessed". The generator now resolves the fix's old-side ranges
(evaluate.hunks, line for line) into case.json, with the declared sites in
the set and the reference's cost, and agree.matches_declared reproduces
matches_v2; a parity test runs both over the recorded outputs of the 15
validation cases (200 probes, identical verdicts) and agree on those outputs
returns the reference's 16 of 20 and $0.022.
agree reports cost_per_candidate (plane spend) and
cost_per_candidate_with_recorded_triage; Requirement 6.2 is judged on the
latter (design.md). --runner-image re-pins the templates from ops/ax/up.sh's

Agent Substrate's golden-snapshot boot runs the same image with the same task env,
so the runner no longer starts its command by itself: after the workspaces are
ready it waits for POST /ousast/v1/start (run/task checked, once per boot, refused
after a delivered run). The reconciler sends it through svc/atenet-router with
ate-target-actor, which never addresses the golden actor (plane/router.py), and the
bound Model's secretKey variable travels only in that body, into the child's env.

The live cluster ran the task command twice: in the actor and in Substrate's
golden-snapshot boot, which gets the same image and task env. Requirement 4.5

The first live run on the local ax cluster and ax's source (docs/runner.md,
docs/sandbox.md, internal/controller/reconciler.go, internal/server/server.go)
showed a lifecycle the task-3/4 code did not model:
- `ax apply` creates a Task Suspended (Ready=False, TaskSuspended); it runs only
after `ax resume task`. The first resume of a new image can fail with
DeadlineExceeded while Agent Substrate builds the golden snapshot, and ax's
server then stores phase Failed; a later resume succeeds.
- ax has no Completed phase and never reads a command's exit back.
- The runner is PID 1 and must keep serving after the command exits; stop and
suspend deliver SIGTERM, to be forwarded to the command's process group.
Our runner imported the task in-process and exited, which stopped the
container ("Container guest is stopped") and made every resume time out.
- ax's controller probes /readyz?check=workspace; the query string made our
handler answer 404.
Runner (Req 4.1-4.4): spec.command runs as a child
`python -m openultrasast.plane.tasks.<name>` in its own process group, cwd the
first workspace, AX_METADATA_URL set; ax's metadata paths are served. After the
child exits the runner reads summary.json (a crash without one becomes failed
with the exit code and stderr tail), delivers the output directory, writes
/workspace/.ousast-state/<task>.done.json and serves until SIGTERM (forwarded
to the group, SIGKILL after OUSAST_TERM_GRACE, exit 0). A boot with the marker
never reruns the command; a failed delivery is retried alone. Workspaces are
prepared on the first boot only. AX_RUNNER_EXIT_AFTER_COMMAND=1 is the
unit-test escape.
Reconciler (Req 2.2, 2.3, 3.1-3.3): `ax resume task` after apply, retrying
DeadlineExceeded/Unavailable with backoff up to OUSAST_RESUME_TIMEOUT (900 s);
completion is the artifact delivery; Failed after a resume went through, a
vanished task, or no delivery within OUSAST_TASK_TIMEOUT (7200 s) fail the
task with ax's condition message; `ax delete task` follows. Ax gains resume()
and phase() returns the condition message. doctor moves to plane/doctor.py
(tasks.md task 0 allows the sibling) to keep reconciler.py under 500 lines.
Tests: the fake ax follows the real lifecycle (Suspended, a failing first
resume that leaves Failed, Running forever, delivery only after a resume went
through), plus Failed-with-message, vanish, resume-timeout and task-timeout
scenarios; runner tests cover the child's cwd/group/metadata URL, stay-up and
SIGTERM in a real subprocess, SIGKILL of a SIGTERM-ignoring group, and the
marker. The opt-in live test now checks resume, Running, suspend and a second
resume instead of a Completed phase. design.md and tasks.md state the
lifecycle; the module audit manifest counts plane.doctor.

Requirement 1.1 (Task/Workspace/Model use only fields ax documents) and
Requirement 1.4 (no ax field repurposed) were violated: manifests accepted
metadata.namespace and a Workspace git `commit`, and the reconciler dumped
every git field into what `ax apply` receives.
Facts from ax's source (pkg/apis/v1alpha1/ax.proto, internal/workspace/setup.go):
- ObjectMeta is `name` and `atespace` (plus server-set creation_timestamp);
no `namespace`, no `annotations`.
- GitRepo is `name`, `repo`, `branch`, `dir`, `depth`; no `commit`.
- The API server decodes with protojson.UnmarshalOptions{}: an unknown field
is an error at `ax apply` (confirmed on the live cluster: a rendered
Workspace+Model applied cleanly; the same Workspace with `commit` was
refused with `unknown field "commit"`).
- ValidateModel checks only metadata; any spec.provider string is accepted.
Changes:
- manifests: metadata takes `name`, `atespace`, `annotations` (our extension,
never sent to ax); git entries take exactly ax's five fields (depth int);
`commit` in spec.git is rejected with a pointer to the new Workspace
annotation `openultrasast.io/git-commits: "<git name>=<40-hex>,..."`,
validated for unknown git names and non-hex shas.
- reconciler: rendered docs carry only ax fields; each bound Workspace's pins
reach the Task as env OUSAST_GIT_PINS = {"<workspace>/<git name>": "<sha>"}.
A test walks every rendered doc against ax's field lists.
- runner: pins come from OUSAST_GIT_PINS; git is fetched as setup.go does
(init/remote/fetch with --depth when depth > 0/checkout FETCH_HEAD, default
branch main, cloneDestination's dir and placeholder-name rules), then the
pin is checked out. A pinned entry without a branch fetches the commit.
- workspaces: emits the annotation, `dir: repo` and `depth: 1` instead of
`commit`, so generated case workspaces keep <path>/repo at depth 1.
- design.md: ax field names verbatim; pins and model binding as stripped
openultrasast.io/* annotations carried to the task by env.

Adopt the design of google/ax (Task / Workspace / Model manifests, a reconciler,
isolated resumable execution, a runner contract), not yet its software: it needs
Kubernetes and Agent Substrate, lists only Google and Anthropic providers, and has
no pipelines, artifacts or budgets. We add a thin Run layer for those.
Each pipeline concern (classify, triage, repo-facts, verify, judge, recheck, score)
becomes a declared task with its own inputs, outputs and budget. That bounds the
tokens per task and lets each be developed alone. Decisions listed for the

Exploratory, 7 of 17 cases, stopped when the account emptied:
- source-only scope: a model reading every product file puts the vulnerable
function among the candidates in 15/17 (ranker 1/17, vocabulary 2/17);
- per-file triage + per-file 6-step hunts + two-pass agreement: 12/15 candidate
cases on the validation set; 4/7 on the full run, two more in one pass of two;
- precision: 5 pgAdmin agreed findings read against source, 3 true (privileged),
2 false with self-contradicting rationales; agreement cannot catch an error
both passes make;
- cost: $0.009-0.022 per candidate for two passes.
Four instrument defects fixed on the way (model id, provider routing, JSON-mode
final turn, unbounded tool output) void the earlier hunter number. No gate is
met; qualification needs population v3 and a protocol that states the judge
stage, the pass rule and a config-family question.

v1 (1/11) and v2 (0/17 recall, 0/17 sampled precision, 12% completion) show that
fixes learned on one population do not transfer to the next. The causes are
breadth: framework-shaped entry points, module boundaries the frontends do not
resolve, name-matched sinks colliding, and scale.
Options:
- A: continue engine-first;
- B: the model proposes, the engine proves;
- C: narrow the product to one ecosystem.
Recommendation: first run the unchanged tool hunter on the v2 pins as the deciding
experiment.

Every reserved case verified with git and file reads only -- nothing
scanned: pins present and ordered, the sink present at the vulnerable pin,
the fix touching the sink (or LearnPress's declared source-side fix site),
and the sink file hashed at both pins (benchmarks/independent/freeze.py,
record freeze-v1.json).
Each case now carries a benign control from its own history, reviewed by
diff. The mechanical keyword filter was not enough: it proposed an access
restriction, a filter check, API-token scopes, a login change and a
TLS-verification option, all rejected; Ultimate Member and alerta got
hand-picked controls (a WPCS reformat; a dependency change with both sides
still vulnerable). The guard test requires a benign pair per case once

Eleven cases chosen by the maintainer from fifteen researched by advisory

repositories the benchmarks reference -- plus the earlier Ghost
reservation. Four are PHP repositories that ship JavaScript (two WordPress

to the v1 scope (injection, untrusted destination, permissive config).
The development subjects shaped every rule of the last week and can no

something scans it. A guard test fails the moment a reserved repository is
referenced by a recipe, catalog, manifest or measurement outside
benchmarks/independent/. Freezing (pins and sinks verified by reading
source, a benign change per case) is the next step.

Same 500-region PHP run on frozen source: completion 281/406 against 153
(hard cap) and 131 (7.8), no portion killed, per-family findings never
lower, declared target still entailed. Records the 7.9 task, its limits,
and corrects the 7.8 reuse note, which was stated backwards.

Final end-to-end on the 500-region PHP subject: findings identical at 125 either way, completion
slightly lower under portioning (131 of 406 vs the hard-cap-plus-reserve 153), wall time higher
(2,982 vs 2,338 s). Told straight: portioning does not beat the cap on throughput here; it matches
it on what it finds, and what it buys is kill-safety -- a killed batch keeps its streamed answers
instead of losing them. Reaching the same 125 findings is the evidence that streaming loses nothing
the cap kept.
Completion did not rise because the requeue re-asks a killed portion remainder, and on this subject
those are the expensive output-encoding questions that keep hitting the ceiling in smaller pieces,
spending budget without completing. Telling a transient kill from a too-expensive family is the next
lever, not more portioning. Neither approach is release-ready anyway: 32-38% completion against a
95% gate on development data that qualifies nothing.

Four interacting defects surfaced in sequence when the portioner was measured end to end, each
hidden by the one before: run_batch timing polluted by its own retry, a single-attempt path missing
on the partitioned graph every plugin uses, and killed remainders dropped by a fixed chunk list. All
fixed and unit-tested; the end-to-end completion number is re-measuring on a frozen tree.

The joern-gated check passes on the real engine: the taint query streams one line per request, and
the comment-sink and literal-destination controls hold under the streamed form. Two defects the work
exposed are recorded as fixed -- the unportioned evidence pass, and a harvest that read a timed-out
pipe before killing its writer -- and one bypass is recorded as a limit rather than fixed: the reuse
layer re-query of missing ids calls the backend batch directly around the sink-weighted portioning.

The evidence pass bypasses the sink-weighted portioning by design: it is the pass that PRODUCES the
weights, and per request it is cheap, 17,700 answered in 44 s. It was still one all-or-nothing batch
protected only by the ceiling. On a plugin push transaction that batch is 22,125 requests, and under
the CPU and memory contention of concurrent test runs it exceeded the ceiling and cost the whole case.
It now runs in portions of 4,000 requests, roughly ten seconds of work behind one JVM start, with
answers merged and the census kept from the first portion that carried it. Streaming keeps what a
killed portion finished; portioning keeps that kill from being the entire pass.
Task 13.3 records the attempt that exposed this honestly: the case deadline was exhausted with no
artifact, and the failure was mine twice over -- the container mounts src live and the backend was
edited mid-run, and the evidence pass was unportioned. Neither is the algorithm. The rerun uses a
frozen export of the committed source with per-invocation logging.
1,423 tests pass, nineteen skipped; mypy clean.

A hard per-invocation ceiling is all-or-nothing. A batch killed at 301 s lost every answer it had
already computed, and the retry paid a fresh JVM start per part to ask them all again: measured, 116
requests killed at 300 s, then eight restarts carrying the same everywhere-sinks in every part.
Three coordinated changes make portioning, not the cap, the thing that governs cost.
The taint query STREAMS. The census first, then one line per request as it is answered, flushed as
it goes, inside the unchanged fence. The other queries do not stream and need not; the driver
reads both forms, and a legacy single document parses exactly as before.
The driver HARVESTS a kill. The process group is terminated first -- a first cut read the pipe
before killing and a pipe whose writer is alive never reaches end-of-file; the suite own
hanging-engine control sat on that read for twenty-eight minutes -- then the pipe is drained and
every complete line becomes an answer, marked partial. The retry asks only the remainder.
Portion sizing ADAPTS. After each portion the observed seconds per sink visit, less the fixed
start, resizes the rest toward a 120 s target; a portion that did not answer halves the budget
rather than being fitted, because its true cost is unknown and above the ceiling. A portion cut
down to fit puts its remainder back at the front of the queue.
A census LINE carries nothing but the census. A first cut misread a legacy document that carried the
census beside its answers as a census line and dropped every answer it sat beside; a control caught
it. Task 7.8 in contributor-scan.
Verified: 1,423 host tests pass, nineteen skipped, including new controls for the assembler in both
forms and under a kill, for a retry that asks only the remainder, and for the sizer. Not yet
verified: the joern-gated streaming check and the plugin measurement, which wait for the transfer
replay to free the machine and are stated as open in the task.
