Every stage of validate_proposal reasoned only about numbers the proposal itself
supplied, so an internally-consistent hallucination cleared the whole gate (F3).
A new stage 0 reconciles each affected_item against the project's CostBaseline
before the CBC solve: an unknown cost code is rejected, and a real code carrying
a quantity/unit_cost outside the configured tolerance (5% default, relative to
the baseline value) is rejected. Validation, never repair.
The baseline argument is OPTIONAL (None = pre-S4.0 behaviour), but both run
paths set it: the road path projects project.cost_items, the bundle path loads
cost-baseline.json when the bundle ships one. Bundles written before the
amendment stay un-anchored, so the commons-owned goldens run byte-identically;
a baseline that exists but is malformed still raises on both loaders.
F8: the method-specific cap now comes from the METHOD_CAPS registry (measure
type -> fraction, injectable) instead of an energy_efficiency string comparison.
The baseline format and tolerance semantics were decided locally — the commons
amendment (D-A pt. 2) never arrived, exactly as in S3.2. D7 mirroring stays open.
Three portfolio fixtures quoted cost codes belonging to OTHER projects; the new
gate caught them. They now quote each project's own lines, and the two copied
REPLIES tables import the single source instead of drifting from it.
Load-bearing measured (tests/test_s40_cost_baseline_loadbearing.py), six
mutations all red: detach the reconciliation stage; detach the magnitude
tolerance; detach the road wiring; detach the bundle wiring; ignore the injected
cap registry; make the optional loader tolerant of malformed content. Control:
with the road wiring detached the repaired portfolio fixtures still pass, so
they are not masking the seam. 597 -> 612 tests.

Three items on one seam — what a FAILED project does to the wave loop — plus the
snapshot copy they sit next to.
(v) The catch is BaseException, not Exception, and that width was ungated. The
existing collect-and-continue test raises RuntimeError, so it stays green when
the handler is narrowed: measured, the whole of test_portfolio_concurrent_
loadbearing.py (13 tests) passes under the narrowing. asyncio.CancelledError is
the one realistic vector that separates the two — probed first, gather(
return_exceptions=True) COLLECTS it, while KeyboardInterrupt propagates
regardless and could never be helped by a wider catch. Narrowed, a cancelled
member is cast into runs as a fake RunResult and the pass dies in _aggregate,
pointing away from its cause. RED measured.
(t) sum_token_usage excludes a failed project's spend, and that is the honest
answer, not a bug: a run that died before producing a stamp has no provenance,
and inventing one is the fabrication RunFailure exists to avoid. What needed
gating is that those tokens still reach the ledger the global cap is enforced
against — otherwise a repeatedly-failing project burns budget while the meter
reads clean. Pins meter.spent as the pass's real cost, sum_token_usage as the
completed-run subtotal, and their difference as exactly the failed spend. RED
measured against the likely "fix" (sourcing sum_token_usage from the meter),
which is wrong because a seeded meter also carries EARLIER passes' spend; 21
existing budget/portfolio tests stay green under it.
(s) _wave_snapshot uses dataclasses.replace, so a field added later is carried
without touching the function. Not cosmetic: measured, dropping retriever by
hand-enumerating left all 585 tests green — the Step-2 coverage its docstring
credited no longer existed, so the S3.1 retriever seam could be downgraded
mid-pass in silence. Now gated by a property test derived from
dataclasses.fields (not a field count, the shape rejected earlier). The explicit
verdicts copy is retained and separately gated: replace(store) alone shares the
caller's list and takes the byte-identical determinism test RED.
strict=True on the zip is documented as deliberately untested — measured green
when dropped, since gather is built from exactly snapshots, so a test could only
go red by manufacturing a mismatch and would exercise zip rather than this pass.
The new double is registered in the S2.5 consolidation guard's delegating-
overrides list rather than the guard being weakened; it already delegates via
super()._inner_get_response, which test_delegating_overrides_call_super now
enforces on it.
583 -> 586 tests.
