The reachability-first audit (previous commit) found these five with no
import path from any entry point:
- model/judge.py: replaced by model/pipeline.py, which never imported it.
- model/execution.py: the MGD Req 10 execution seam, never built or called.
- model/calibrate.py: no CLI, no importer; learn/calibrate.py is the live one.
- stage_processors.py + slot_contract.py: kept only so test_gate could pin
them; the scan runs findings.quick_scan_findings directly.
Their tests go with them, test_gate's zero-dependency list drops the two
entries, the audit lists drop their rows, and the manifest is regenerated:
150 modules, 145 load_bearing, 5 standalone, 0 orphaned.

model/audit.py classified anything named in SPEC_OWNED or STANDALONE before
looking at the import graph, so five modules nothing imports were reported
load_bearing and the committed manifest said 0 orphans.
- Reachability from the gates, the CLI and every module with a __main__ block
(python -m, the plane runner) now decides the class; the lists only supply
reason text, and an unreachable listed module is orphaned with its listing.
- `from .pkg import sub` now records the submodule edge (plane.engine_alerts
was only reachable by its SPEC_OWNED entry).
- `python -m openultrasast.model.audit` regenerates the manifest.
- Manifest regenerated: 145 load_bearing, 5 standalone, 5 orphaned
(model.calibrate, model.execution, model.judge, slot_contract,
stage_processors). The zero-orphan test is strict-xfail until they go.

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.

99 source modules -> 81. 832 tests -> 646. The whole learning/ package (16
modules, ~4,100 lines) and six semantic/ modules removed, with the three gates
byte-identical to 2026-09-06-gate-baseline.txt at every step.
The sequence is what made it safe: vocabularies ported first (1.1), importers
detached second (1.2-1.3), deletion third (1.4). Every import break during the
deletion was therefore a detachment miss in the importer and was fixed there --
no module was restored to satisfy one. Both misses were the same shape and were
fixed as a class: operations.py and shapes.py each imported trailing_name from
the deleted variants.py, so it moved to semantic/ir.py, its natural home, and
both importers changed in one edit.
Ported before deleting: the closed guard vocabulary (verbatim, nothing else
holds it) into model/specs.py, which derives TaintSpec and DominanceSpec from
the retained ruleset facts rather than copying them. Re-homed: families ->
model/taxonomy, candidates -> model/candidates, endpoint -> model/endpoint,
plus Region, labeled_family and labeled_spans. labeled_family no longer falls
back to the LLM classifier -- an unlabeled pair is honestly unknown.
Four deviations, each recorded in the spec notes with its reason. improve/
evolve.py and validator.py were stripped, not deleted: each mixes the mechanism
lever (gone) with the deterministic rule-status loop `ousast improve` still
runs, which has no LLM in it; a test now asserts the lever's absence by symbol
so it cannot creep back. The learning CLI group became `model candidates`,
because deleting it outright would have orphaned the retained enumerator by
removing its only entry point. thinking moved from [learning] to [models].
A gap named rather than papered over: no retained sink fact routes by CWE to
path, output_encoding, untrusted_destination or prototype -- the same hole the
entailment ceiling diagnosed. The test asserts the seeded set and the gap set
exactly, so task 4.2 must update it when it authors those sinks.
The audit found exactly one genuine orphan: vectorstore.py, a bakeoff harness
with no production caller and no CLI, alive only through its own test. The five
named subsystems each carry an explicit decision. Manifest committed, with a
test asserting the tree still matches it.
Group 2 (the Joern go/no-go) has not started.
