Maintainer's finding of 2026-10-14 recorded in hunter-learning-loop (a dated section that overrides the shape
annotations as the model's input), its design (amendment pointing to the prover's trace) and the steering
overview's current state.

Off every active line (PATHFINDER-2026-10-13/03-unified-proposal.md, cuts).
Deleted: src/openultrasast/regress/ and the deep-mode REGRESS branch (deep
now records a regress_retired degradation and equals standard; proof is the
search-with-proof arm's job), the sandbox docker runner and probe that only
regress used, --fail-on worth-fixing, RegressConfig, the two ledger helpers
only regress called; skills.py and index.py with the hunter pool's skill
routing; model/audit.py; cpg/queries/vocabulary.sc with
benchmarks/push/ontology_gap.py. Docs and the scan skill describe the
retirement. Net: 3,895 lines deleted, 86 added. Targeted tests: 180 passed,
28 skipped; 3,331 tests collect.

fossil-mcp dead-code over src found 72 candidates; 69 are referenced by tests,
__all__ or other modules, 3 are not and are removed (cli._first_source,
pairs._scorable, provider.openrouter._extract_message_content). Eight spec
directories that steering already called retired or superseded leave the tree
(history keeps them, commits named in overview.md): harnessx-removal,
harnessx-self-improving-rulesets, openrouter-sast-harness, learning-harness,
constrained-detector, three-stage-scan, real-world-vfc-slice,
unseen-repo-evaluation. overview.md gets a current-state section: the valid
benchmark numbers, what they say, and the four active lines in order.

Maintainer 2026-10-04: the safety net is for unseen code and the A/B tests exist
to prove the approach generalises; infrastructure work had drifted from that.
Runs are designed for AX on kube-ax, kind is the fallback.

Legacy inventory 2, the six STATUS NOTE items (the archive README row landed with the R2 commit).
ai-service-plane: 11 of 11 tasks checked, spec.json phase set to implementation-complete as 5b96199
did for four other specs. contributor-scan: dated note in requirements.md -- paused since 2026-09-23,
27 of 51 tasks, v1.2.0-alpha.1 NO-GO, remaining tasks wait on pre-push M2/M3. finding-feedback-loop:
dated note -- dormant, design unapproved since 2026-09-09, depends on the paused spec. The steering
overview's spec table carries the same three states, its leftover 2026-09-09 module-count line is
removed and the collected-test count is the measured 2,023. docs/memory-and-detection.md names the
archive path of model_sinks, the one stale script name left in docs after 067adb9.

The plane's memory store no longer names one vendor. `MinioStore`/`SdkClient`/
`minio_settings`/`MINIO_KEYS` become `S3Store`/`S3Client`/`s3_settings`/`S3_KEYS`;
the URL scheme is `s3://<bucket>[/<prefix>]` (`s3://` alone uses `S3_BUCKET`); the
settings are `S3_ENDPOINT` (a full URL), `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`,
optional `AWS_SESSION_TOKEN` and `S3_REGION`. The client is boto3 (extra `s3`,
imported lazily): SigV4, path-style addressing, SDK checksum trailers off, paginated
listing, versions and delete markers listed and deleted by version (`purge`, used by
the contract tests' teardown so the bucket keeps nothing of a run).
Behaviour is unchanged: the store never configures its bucket and verifies
versioning, the `runs/` expiry rule, S3 Select and tag reads at startup; no local
fallback; every row carries every queryable field with "" placeholders. The admin
hints read `--endpoint-url "$S3_ENDPOINT"`. The fake client still reproduces RustFS's
two Select failures (unbound leading-row field, null-typed column).
Docs: rustfs.md stays the tested server's setup page (policy JSON unchanged, env
names updated, any S3-compatible store with versioning, lifecycle, tags and Select
works); memory.md, ops/ax/README.md, README.md, steering and the two current spec
designs use the S3 naming. Retired specs and committed measurements are untouched.
Real server (RustFS, OUSAST_MEMORY_TEST_S3=1): test_plane_memory + test_learn_compile
75 passed, 1 skipped. Store copy of the live local store to a temporary prefix: every
count matched (776 row objects, 2982 rows, 22 facts, 788 excerpts, 2601 responses,
2 programs, 1793 index entries), 4190 versions purged afterwards.

A4: roadmap-2026-09-04.md moves to .kiro/archive/steering/ so it no longer
loads as steering (roadmap.md and safety-net.md replaced it); roadmap.md's
pointer follows it. overview.md's spec table is recounted from tasks.md and
spec.json (adds ai-service-plane, harnessx-removal, learned-decision-engine,
pre-push-safety-net; drops the stale "active one"), and the module line now
cites the regenerated audit: 150 modules, 145 load-bearing, 5 standalone,
0 orphaned; 1,964 tests collected.
A5: a dated status note at the top of the requirements (or brief) of 16
specs: retired, superseded, dormant or complete, and for
model-grounded-detection the removal of judge/calibrate/execution (closing
the Req 10 execution-tier option). spec.json phase corrected to
implementation-complete where every task is checked (model-grounded-
detection, propose-adjudicate-prove, tree-sitter-overlay-extra,
corpus-seeded-mechanisms, pair-corpus-honesty); openrouter-sast-harness gets
a spec.json with status retired. Nothing deleted, no spec moved.

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.

The scoreboard now carries a real finding: CVE-2023-23488 at
class.memberorder.php:936, the exact line, in unmodified plugin code, with
16 of 26 unprepared $wpdb queries reported in that file and zero of the 26
using ->prepare.
And the reading the maintainer's instinct produced: **the first real CVE
was found by cutting, not by scanning more.** Two of 637 files load in 9
seconds and report the bug; the full checkout does not load at all.
That two-file slice IS the contributor case -- a developer editing
class.memberorder.php gets precisely that scan -- so scoping is not a
workaround for a scale problem, it is the thesis, and the scale problem is
what happens when the thesis is ignored.
The distinction recorded is not whether to cut but who decides and whether
the decision survives: a build declaration, a diff or a subtree is chosen
by the project or the developer and is recoverable from the artifact, while
a model judging "this looks like boilerplate" gives the same answer when
right and tells you nothing when it drops the file holding the bug. Every
failure found on this checkout was of that second shape.
Also corrects "one language is demonstrated" to two, with the honest limit
attached: PHP works on a real plugin slice and not at repository scale.

Three directions recorded, each grounded in what this session measured.
**WordPress by flaw class, not by plugin** (tasks 5.8, 5.9). One plugin is
a checkout; a class is a claim. WordPress's recurring shapes are narrow and
each maps to a family that already exists -- unauthenticated wp_ajax_nopriv
reaching $wpdb, a missing capability check, unescaped output, arbitrary
file operations. Two of the four are blocked on gaps this session found:
access control cannot be asked at all because PHP has no obligation facts
(5.9), and unescaped output is blocked on the flat sanitizer list (5.6).
The observable is a class-by-class table across several plugins saying
found, missed, or out of scope -- a single found CVE is not the artifact
worth teaching from.
**Why a corpus of benchmarks is not enough on its own**, written into
overview.md as the finding it is rather than an opinion. Twelve engine
defects in one session against three real repositories, and the three gates
stayed byte-identical through every fix. A gate that does not move is a
corpus that could not see the bug. The reason is structural: a pair is a
labelled function with a declared family and a known answer, so it cannot
exercise which region to look at, what to spend, whether a capability is
reachable, whether two entry points share a sink, whether the question fits
in an argv slot, or whether a flow crosses a module. Three of the twelve
were quiet failures where the tool reported clean and every honesty counter
agreed -- which a benchmark score cannot express, because the score is
computed from the verdicts that exist. The corpus is the holdout that stops
per-repository tuning, and the wrong instrument for finding out whether the
tool works.
**ir-consolidation** (brief, unapproved) separates two questions the IR
suggestion contains, which have opposite answers. The SOURCE IR is already
carried rather than about to be added: semantic/ is 3218 lines, 16% of the
codebase, measured at 2.2% entailment against the CPG's 41.3% and still
running as a proposer -- and Vine and P-Code are binary IRs, so the work
there is subtraction. The MISSING abstraction is C arithmetic, and there
GhidraPAL's three-valued-logic abstract interpreter over Ghidra P-Code is
exactly the right shape: "can this index exceed this allocation" is a value
question, which is what a bit-level TVL domain answers and what every
libpng overflow needs. Vine is dormant since 2009 and is not the candidate.
The constraint is recorded as an ordering: question 1 lands before question
2 starts, or adopting an IR makes the growth problem worse. And the cost
that matters is not lines but the number of things that can silently return
nothing -- this session found three such in a single PHP scan, and a binary
pipeline adds a build, a lifter and a domain, each able to produce an empty
result that looks like a clean one.

Fourteen specs have accumulated and the roadmap still described a
pre-Joern world -- "adjudication is still Python-ast plus a tree-sitter CLI
stub", "Joern-as-required deferred" -- which is stale enough to mislead
someone reading it to decide what to do next. It is kept as
roadmap-2026-09-04.md rather than deleted.
**overview.md** is the synthesis above the specs: what the tool is, how one
pass works, what has been measured, and what is not true yet. Every number
cites a committed artifact. The thesis is stated plainly -- the
differentiator is not the dataflow engine, since CodeQL and Semgrep have
one and developers do not turn it on, but the rung: a claim you can act on
without writing a query, and an explicit admission when the engine could
not decide.
It says what does not work as clearly as what does. The C story is
structurally broken, not undertuned. One language is demonstrated. PHP,
Ruby and Go have zero families, so Joern would parse them and the engine
would say nothing. The evidence base is two repositories and one has never
produced a true positive. Control dependence is unavailable in both CPGs.
execution_confirmed has no production caller.
And it records the lesson that shaped the current specs: nine defects found
by pointing the tool at two real repositories, three of them the same bug
in three matchers, with the three gates byte-identical through every fix --
so a corpus of function-level pairs could not have caught any of them.
**roadmap.md** is ordered by the standing test, that the tool must find
bugs or it is SAST noise. Which gives the ordering principle: make the
output worth reading, then make it find more. A better arbiter behind an
unreadable report changes nothing, and a second language before the report
is fixed doubles the noise.
It also says what is NOT being worked and why -- authorization-obligations
and reachability-flow-model were largely delivered by other routes and
should be reconciled or retired rather than carried as approved-not-started,
which misrepresents both.
