Point 2 of the sweep, enumerated rather than assumed. STATE's total was right and
its distribution was not: 86 hits confirmed (`assert not X` 41 / `== []` 42 /
`== {}` 2 / `== set()` 1), but per file measured `test_cli_paritet` 13 (STATE said
19), `test_preflight` 10 (11), `test_step7` 4 (6).
AST triage split the 86: 55 hits sit in 50 tests whose assertions are ALL
negative; the other 31 already have a positive sibling assert in the same test.
Two negative results worth recording, because they bound the remaining work:
- The `test_preflight` "clears" family (`_check_credentials(...) == []` and
friends) is NOT vacuous. Each sits beside a sibling in the same class that
asserts refusals are non-empty, so a no-op checker turns the sibling red.
Class-level pairing is a real control; these need no change.
- `test_method_spec_loadbearing.py` already models the right pattern for
detectors — explicit `test_guard_red_when_*` red-proofs against a mutated COPY.
This commit fixes the class that had no control at all: static/AST guards that
assert an absence without ever showing the scanner can detect a presence.
1. TAUTOLOGICAL RED-PROOFS (both spec guards). `test_guard_red_when_spec_missing`
asserted a file is absent from a fresh `tmp_path` — true by construction of the
fixture, and it never called the guard it is named for. It would have stayed
green with `test_spec_is_present` deleted outright. Both now exercise the same
`_spec_is_present` predicate the guard calls, in both directions.
2. MISSING RED-PROOF. `test_spec_keeps_structure_markers` had none, unlike its
toolkit and contract-field siblings: with `_STRUCTURE_MARKERS` emptied or
`_missing_markers` stubbed to `[]` it reported green forever. Added
`test_guard_red_when_marker_removed`, parametrized over all 21 markers.
3. BLIND IMPORT SCANNERS (costsim x2, okf, preflight, notify). Every one asserted
`not names & {forbidden}` or `outside == set()` with nothing showing `names`
was non-empty — an empty scan satisfies them exactly as well as real purity.
`test_okf_is_pure_stdlib`'s subset check is likewise trivially true of the
empty set, so it did not guard its neighbour either. Each now asserts a
known-present module first. The notify guard gets the strongest form
available: it proves the detector DOES match a network import inside the seam,
so the matcher itself is shown to work rather than only its silence.
Value-proved, not merely detach-proved. Seven vacuity mutations run against the
NEW tests: all seven RED, each dying on the intended control line. The same
mutations run against the PRE-CHANGE tests (session edits stashed): all five
applicable ones GREEN — blind to the vacuity they were meant to catch. Green
before, red after, same mutation, is the value-proof.
Harness held original bytes in memory, restored in `finally`, sha256-verified
every restore, and checked each run ACTUALLY RAN (a wrong test id yields rc!=0
and mimics red). `git status` clean before and after.
Remaining in the class and NOT closed here: ~45 all-negative tests, mostly CLI
refusal (`calls == []` after a refused invocation) and empty-default
(`missing dir -> []`). Listed in STATE, not silently dropped.
Suite 690 -> 711.

Oekt 17 found the class on four named files. This sweep ENUMERATES it: 42 negative
substring assertions across 21 test files (STATE's "~34 across 23" was a premise --
measured, it is 42/21). Sixteen of them measured an absence without ever having
shown presence; all sixteen now carry a positive control asserting the searched-for
string PRESENT in the source artifact, in EXACTLY the form the negative looks for.
Files touched: test_costsim, test_loop, test_okf (3 sites), test_preflight,
test_run_entrance, test_s10_run_layer, test_sdk_version_guard, test_simulation
(2 sites), test_step1_expel, test_step5_refine, test_step7_async_loop,
test_step8_promotion, test_valuereport.
VALUE-PROOF (green-without / red-with, per the oekt-17 rule that a detach proof is
not a value proof). Seven source/fixture mutations, each making the negative vacuous:
M1 verdict fixture loses the realization signal VALUE-PROVEN
M2 decoy fixture loses its text VALUE-PROVEN
M3 renderer stops emitting typed section headings VALUE-PROVEN
M4 promotion stops writing the marker VALUE-PROVEN (pass 2)
M5 fold stops rendering the realization surface VALUE-PROVEN
M6 report stops labelling the cost section VALUE-PROVEN
M7 preflight stops importing the SDK VALUE-PROVEN
M4 needed pass 2: a PRECEDING assertion caught the same mutation, hiding the new
control behind it -- the oekt-17 lesson reproduced. The remaining nine controls are
vacuity guards (non-emptiness / form-presence) whose mutation would have to break
the source artificially; they are stated as guards, not claimed as value-proven.
MEASURED FINDING (test_loop): the FIRST-RUN-MARKER negative cannot be given a
positive control at all. Within a run only the CHECKER's critique is fed back --
the proposer's own prior reasoning crosses no prompt boundary, not even within a
run. So that negative holds trivially. Left in place with the limitation stated in
the test rather than dressed up as a controlled seam; the CRITIQUE negative beside
it IS controlled and is the real seam.
Mutations were in-place on src/ and shared/ with original bytes restored and
sha-verified; git status clean before and after. Suite 688 -> 688 (assertions added
inside existing tests, no new test cases). ruff + mypy --strict green.

Before ANY spend the operator sees a deterministic UPPER-BOUND USD estimate
for a (portfolio-)run — a what-if over the models in model_map.json (Claude
models) × effort levels (S3.6-analog, D-I pkt. 3 MUST-krav). No network, no
model call, no key: pure config arithmetic (bound by an import-purity test,
mirroring okf.py).
- contracts.py: ModelPriceContract (usd_per_mtok > 0 + REQUIRED source +
source_date so a stale rate is visible, never silent, §1) + PricingContract
(non-empty; no hardcoded fallback rate) + load_pricing/_bundled_pricing.
- data/pricing.example.json: per-Mtok rate per model id, each with source+date.
Example rates are Anthropic's OUTPUT price (the higher rate) so the whole cap
billed at that single rate can only overstate — the figure is marked ESTIMAT.
Covers the model model_map configures, so the default path runs green.
- costsim.py: estimate_costs (n_projects × cap × effort_factor tokens at the
per-Mtok rate; a model with no price fails fast "missing price for <id>",
never a guess) + render_estimate + `python -m …costsim`. Effort factors are
a coarse modeling weight (not prices) — max effort = full cap = the true
upper bound. No price literal anywhere (grep-guard proves it).
- tests/test_costsim.py: schema fail-fast, missing-price fail-fast, scales with
model × effort + reproducible, grep-guard, import purity, bundled-example +
CLI offline smoke. Three seams detach-proven RED (effort factor, price guard,
price literal).
462→478 green, golden byte-exact, full gate clean (ruff+format+mypy strict,
23 src files), run_s10.py/runs/ byte-untouched. README test-count sync ×2 +
costsim.py module note. CLI run-total-cap wiring stays out of scope (planen
lists 4 files); the mechanism is complete and proven load-bearing.
