ADR-0006 D3. Nine standing control gates now say what they check, what
they have caught with pointers, when their keep-or-kill argument is due,
and what would retire them. make gate-review reports what is overdue and
what has caught nothing; it never fails the build, for CB-RES-0005 §4's
reason.
Drift is checked in both directions and both are pinned by self-tests: a
dependency of `make all` that is neither a registered control gate nor
listed in not_control_gates is a loop-lint finding, so a new gate cannot
acquire permanence without a review date, and an entry naming a target
the Makefile lacks is a finding too.
First run: 0 due, 2 silent. The silent two are the chaos roll, whose
12-declaration window exists precisely to find out, and gate-review
itself, which is not exempt from its own rule — if it has retired,
tightened or forced the re-justification of nothing by 2026-12-31 it is
a ritual and goes.

A human seat is a Policy like any bot, so the CLI adds no second driver:
HumanPolicy renders the projection, lists the legal commands and reads an
index or `pass`. `make play` runs it; `--all-bots` watches one.
K13's Project trait gains its first implementor after six passes with
none. Hidden: other seats' face-down selections until Reveal, hands and
deck (counts only), a face-down Problem's suit and value, and the seed —
not secret content, but a seat holding it can compute the deck.
A played session becomes an artifact: --record writes it as a scenario
the runner executes, --replay writes a .cbreplay bundle. record.rs is the
inverse of parse_command and its warrant is a round-trip test over every
command shape.
The acceptance test for the projection passed vacuously twice. First it
asserted the text contained "face-down", which every render does because
of Problems. Counted, it then reported zero inspected entries: seats are
asked in order, so a human at P1 is prompted before anyone has selected.
Seated at P3 it inspects ten entries and dies when the projection is
mutated to reveal everything. Counting what the harness examined caught
both, which is the second time that remedy has worked where a stronger
predicate would not have.

Scope cut first, on the maintainer's decision after a spend review: the
project is 38% product / 62% loop-meta, cost per response is 2.9x worse
than its best window, and INTENT stage 0 still lacks a CLI player and
bots. CB-WP-0005 and CB-WP-0006 cost ~$74 — 31% of all spend — for zero
measured efficiency gain. T02 and T04 are cancelled unstarted.
T01: SH-1/SH-2/SH-3 now report over the window since the last commit, and
the cumulative figure is retained but labelled "history, NOT the metric".
The prediction held decisively — window 655,744 mean context against
cumulative 255,307, a 2.6x gap against a 20% refutation threshold. A
cumulative mean over 1,094 responses cannot detect a worsening trend
because the history outvotes the present.
T03: `make shape-budget`, modelled on CB-01/CB-02. Soft thresholds are the
existing SessionShape targets; hard is 1.5x, set before the next
measurement per §Step 4. Deliberately not in `make all` — failing the
build on context would block committing, and committing is what closes the
attribution window and is the natural point to compact, so a gate that
blocks the remedy is a trap. It fires HARD on its first run: 656,574
against a 300,000 ceiling.
InnerLoop v1.5 establishes the soft 25% meta budget. Workplans declare
kind: product|meta|mixed and `make status` reports the share; mixed splits
50/50 and says so. Soft on purpose — a task already started may be
finished, because stopping mid-task to satisfy a ratio wastes the work.
What it forbids is opening new meta work above the line. A pass that
exceeds it must say so in its evidence and name the product work
displaced.
First reading: 68% OVER, of $74.22 attributed. Product reads $0.00 because
the only product workplan, CB-WP-0001, predates qualified task ids and its
bare T## labels collide across passes — stated in the output rather than
papered over.

INTENT design decision 8 of 10, unimplemented for six passes. cb-sim had
no flag parsing at all, so --replay had nowhere to go.
The bundle is manifest + commands.log + initial.snapshot + expected.yaml,
dev-only behind the scenarios feature and charged to AM-4b. The command
stream goes through the K11 framing built in T05, so a truncated bundle is
detected rather than replayed short — the two tasks compose rather than
duplicating.
The reviewer's D2 correction was real: this was not "a directory of four
files". Pass carried only the end state, RunOutcome::Failed was a
formatted String, and scenario.rs created an EventLog, appended to it and
never read it. All three had to change.
The first round trip failed to reproduce, and the cause is worth keeping:
state_hash_hex over a serde_json::Value is a different canonical form than
over the typed aggregate — Value's map is key-sorted, a struct serializes
in declaration order. The bundle was written with one basis and verified
with the other. A round trip written to recompute its own comparison value
would have PASSED this bug; it failed because the recorded hash came from
the producing process, which is control 2's entire purpose.
make replay-test implements ADR-0005 §6's four controls, 14/14: a
committed deliberately-failing fixture outside the corpus with covers: []
so it neither fails `make sim` nor inflates AM-1; a tampered recorded hash
must fail; a log short by one byte and a corrupted length prefix must be
rejected; and a mutated manifest seed must fail — which bites only because
replay re-derives the initial state from seed+setup and checks it against
the recorded snapshot, since restoring from the snapshot alone would leave
the seed inert. Plus a control on the controls: the bundle must still
replay after every mutation is reverted.
AM-7's hash-identical clause is re-earned. The probe records a hash per
per-game segment and replays each from its own genesis; folding from the
wrong seed now fails. That is the clause ADR-0005 §4 withdrew as
mutation-proven inert. The scaling >= 0.9x clause is still unenforced, so
AM-7 stays PARTIAL — reported, not rounded up.
Kernel coverage 15/18 -> 16/18. facts-check immediately caught the spec's
copy of that number going stale, on a number that moved the same hour.

AM-4c is withdrawn from the acceptance table and retained as a reported
diagnostic. GameKernel §5a carries the argument.
The ratio has no monotone better direction. INTENT's rule is "own the
semantics, assimilate the implementation": rising can mean owning
semantics properly or reimplementing what should have been assimilated;
falling can mean leverage or dependency bloat. A target requires knowing
which way is better. It is also redundant — AM-4a/AM-4b bound the
denominator and AM-2 bounds own-source density, so AM-4c is a ratio of two
already-targeted quantities.
Measured at withdrawal: 1,426 own lines per 100k third-party (shipped),
1,107 (dev). make dep-weight now prints both, labelled diagnostic — the
row was never actually reported before.
M-D1-MUT keeps AM-4c in its denominator on purpose and says so in the
output. Dropping it would move the score 7/14 -> 7/13 without enforcing
anything: a score improved by deleting the question.
Decided before Phase B deliberately, since ADR-0005 predicts own-source
growth that will move this ratio; deciding after would be the retarget
§Step 4 forbids.
A T01 correction found here. The AM-6 gate failed inside `make all` at
38,753 ev/s against 341,280 in isolation — a 9x drop, because cargo test
runs binaries and threads concurrently. A throughput assertion inside a
parallel harness measures contention, not throughput. T01's measurement
was valid; its gate placement was not.
Fixed by running it only where valid — #[ignore] plus `make am6` in
release with --test-threads=1, now 2.0M ev/s at 20.2x headroom — and not
by lowering the target, which T01 forbade. My first attempt did drift that
way, adding a debug "sanity floor" of 50,000, and was backed out: a second
threshold is still a second chance to tune.
The mutation then went SURVIVED on the first run after the move. 4,000
black_box iterations were calibrated against debug's 3.4x headroom and are
invisible against release's 20x. Raised to 100,000; back to red. A weak
mutation is not a fixed property of a row — it can become weak when the
row's measurement conditions change.
Tier S (amends one row, creates no capability), chaos d4=2, no override.

AM-9 is met and gated: 13.4 MB peak RSS against a 64 MB target, 4.8x
headroom, in `make all` via --fast. CB-EV-0001's "very unlikely to bind"
was right, but it is now measured rather than assumed, and verified red by
a property mutation (a 300 MB allocation in the workload).
AM-5 is BREACHED on both readings, on the machine the spec names:
dev toolchain (default features) 87.0 s [FAIL target <= 60 s]
shipped runtime (--no-default-features) 61.3 s [FAIL target <= 60 s]
bnt-lap001, 8 cores — a direct comparison, not a directional one. A row
declared "recorded not gated" and never recorded fails its own target by
45% on first measurement.
The tool reports and exits 0 because the spec says the row is ungated.
Gating it is a spec change needing an ADR; a tool that promotes itself is
how a target starts binding without anyone deciding it should. So AM-5
stays unmutatable — for the accurate reason now — and the breach is raised
as a maintainer decision: speed the build, move the target by ADR (arguing
why 60 s was wrong rather than why 87 s is convenient), or withdraw the
row.
The measurement itself had a real bug, found only by cross-validation.
getrusage(RUSAGE_CHILDREN) is a high-water mark across every reaped child,
so it attributed cargo's memory to the workload and reported 38.2 MB for a
run that used 12.3 MB — a 3x over-report that was plausible, passed its
target, and would have been published. Fixed with os.wait4, which returns
that specific child's rusage, and the self-test now cross-checks against
/usr/bin/time -v.
That is the false-accusation shape in the measurement layer rather than
the mutation layer: an instrument confidently reporting a number it had
not earned.
Also: the clean build measures into a throwaway CARGO_TARGET_DIR rather
than running `cargo clean`, so measuring the metric does not cost several
minutes of rebuild afterwards. A metric that punishes its own measurement
gets measured once and never again.
M-D1-MUT: 6 -> 7 of 14.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Both rows were unmutatable for the same stated reason. They resolved
differently, and the difference is the point.
AM-2 is instrumented and enforced — tools/size-metrics.py, in `make all`:
AM-2: 27.2 LOC/rule [ok target <= 40] (1.47x headroom)
1,575 impl lines / 58 rules
Tests are excluded because AM-2 asks what a rule costs, not how much it is
exercised; lib.rs is ~18% test code and including it would have flattered
the number. This matters because AM-2 is AM-1's anti-gaming pair: 100%
rule coverage means nothing if the rules are trivially small, and AM-1 has
been reported met since CB-WP-0001 with its pair uninstrumented.
Verified red by a property mutation — ~800 lines of filler injected into
the impl, pushing the ratio past 40 — not a threshold tweak. The expect
string is the precise failure signature "FAIL target <= 40"; my first
attempt used "AM-2", which also matches passing output and would have
made the FA guard vacuous.
AM-3 is BLOCKED, not uninstrumented, and that is a finding rather than a
deferral. It measures LOC to express the CB-RES-0001 synthetic game on our
kernel, against a boardgame.io baseline of ~36 LOC for a declarative 3p
commit/reveal game object. That artifact has never been built: games/
contains only ground, and benches/synthetic.rs drives GROUND rather than
defining a synthetic game. Measuring GROUND's 1,575 impl lines against a
36-line synthetic game object would compare two different games and call
the difference a D1 result.
So the tool ships the measurement — a marker-delimited region, self-tested
— and reports the row blocked, naming the missing artifact. A number would
have been worse than a blank. It stays unmutatable and still counts
against M-D1-MUT per ADR-0005 §1: a row that cannot fail asserts nothing,
however good the reason.
M-D1-MUT: 5 -> 6 of 14.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
For each acceptance row in GameKernel §5, invert the property and require
the verifying command to go red. adapted:mutation-testing, with the
denominator changed from source lines to acceptance rows.
M-D1-MUT: 4/14 rows enforced
PARTIAL 2 (AM-7, AM-8 — some clauses live, some inert)
unmutatable 8 (no property to invert, reason stated per row)
SURVIVED 0
Two corrections to our own numbers. There are 14 rows, not the twelve
ADR-0005 and CB-WP-0005 both asserted — AM-4 splits into a/b/c. And the
prediction of 9-of-12 (75%) becomes >=10 of 14; measured 4 (29%), badly
unmet. No target moved in this commit.
The second correction matters more. My first run reported two SURVIVED
rows and both were my own no-op mutations: `pub struct NullRng;` ->
`pub struct NullRng {}` is semantically identical, and renaming
max_age_days does nothing because CA-17 reads it with a default of 90.
Both would have been published as "this row asserts nothing" — a false
accusation against code that is fine. Replaced with real inversions (a
per-construction counter in the ChaCha seed; reverting AC-9's output
resolution to the first-wins bug it was fixed for), after which both go
red. T08 asks whether writing a weak mutation is the new grep. It is,
demonstrably, on the first attempt.
The finding is larger than the workplan assumed. 8 of 14 rows are
unmutatable — AM-2, AM-3, AM-4c, AM-5, AM-6, AM-9, AM-10, AM-11 have no
instrument at all. AM-6 is the sharpest: nothing in the workspace
compares any number to 100,000 events/s, the headline throughput claim.
The problem is not three unimplemented rules, it is that more than half
the acceptance table has nothing behind it.
Harness controls: a stale find-string reports HARNESS-BROKEN rather than
scoring the baseline as the mutant; a red baseline reports inconclusive
rather than red; the tree is restored in a finally and the restoration is
verified. Not in `make all` — it rebuilds the workspace once per row.

Duplicated-fact drift is the fourth error class and the only one with no
executable rule. No positive control catches it (both copies are
internally consistent) and re-derivation does not either (the copy
reproduces whatever it was copied from). It is caught only by reading a
copy against its source, which nothing in the loop required.
facts.toml holds 15 facts and is GENERATED by `make facts-gen` from
cb-cost, dep-weight and rule-coverage. The trap this task named — a
hand-maintained registry that becomes another drifting copy — is closed
by facts-check re-running the instruments and failing when the committed
registry disagrees with them. A stale registry cannot certify stale
artifacts.
An artifact quoting a fact tags it: **$93.15** <!-- fact --> with the key.
17 occurrences across 5 artifacts are now checked.
Falsified before being believed: changing CostAccounting.md line 158 from
$93.15 to $92.87 — the exact historical drift — produced exit 1 naming
the file, the line and the expected value. Tested against the class it
exists to catch, on a real artifact, not only in its self-test.
It then caught a live tag inside its own documentation example in
InnerLoop.md within the hour. Third time a gate has failed on its own
pass's work.
What it does not close is stated rather than implied: 22 untagged literal
copies remain and are reported, not failed. Tagging is opt-in, a number
can legitimately recur, and a gate that fires on coincidence gets routed
around. Naming the uncovered surface beats claiming the class is closed.
InnerLoop single-source-of-fact moves from prose to executable — v1.3.

49 turns and $6.87 per CB-RES-0003 went to grep/ls/wc answering "what is
the state of this repo". tools/status.py answers it in 22 lines: commit
and working-tree state, every workplan with task counts, the next todo
task, spend since the last commit against CB-01/CB-02, and the three fast
gates.
Two constraints are deliberate. It does not build — a status command that
takes two minutes gets replaced by `ls` within a day. And it states its
own limit in the output ("slow gates not run here"), so a green status
cannot be misread as a green `make all`; the self-test asserts that line
is present, and that the whole report stays under 40 lines.
The positive control is the refusal to be confidently empty: a parser
that found zero workplans and zero tasks would print a clean, wrong
picture, which is worse than the greps it replaces. It also caught a
dot-all regex that returned twenty paragraphs of the preceding task's
prose as the "task heading".

Replaces the three hand-done steps of a task close (46 turns, $11.52 per
CB-RES-0003): the heredoc flipping status in the workplan file, the
hand-written hub call, and the hand-typed token counts.
The third is the reason this task exists. Every update_task_status this
repo produced carried estimated tokens_in/tokens_out — in a project whose
central finding is that estimated token counts are worthless. task-done
reads the measured figure from the transcripts, or refuses; there is no
path through it that emits an estimate.
cb-cost gains by_task_detail: cost, response count, model histogram and
token components per task. task-done imports cb-cost rather than parsing
its printed table, so the hub figure is not a copy that can drift from
its source.
The positive control found a real defect before the tool ran once.
Attribution keyed on a bare T\d\d from the commit subject, so CB-WP-0002
T01, CB-WP-0003 T01 and CB-WP-0004 T01 shared a bucket: the self-test
reported $12.10 for "T01" where the qualified figure is $2.33. That 5.2x
overstatement would have been pushed to the hub as a *measured* number —
the same fiction in a new form. task_label() now keys qualified subjects
on the full id and leaves unqualified ones bare rather than
retro-assigning them to a workplan. The pinned $93.15 benchmark is
unchanged, so historical attribution was not disturbed.
Fourth instance of trusted arithmetic: a number believed because a
program produced it rather than a hand.
Refusals, all exercised by --self-test: unknown id, typo'd id,
already-done task, missing state_hub_task_id, no measured spend, and a
status flip that produced no change.

CB-RES-0003 measured 84 turns and $15.33 — the largest mechanical
category — spent prefixing commands with `cd` and
`export PATH="$HOME/.cargo/bin:$PATH"`. Both causes are now fixed once
instead of per-leaf.
tools/repo.py resolves the repo root from __file__ and cargo from PATH
then the standard rustup locations. Every tool imports ROOT from it, so
the repo path is stated once rather than redefined in four files —
single source of fact, the rule DFD earned in InnerLoop v1.2.
rule-coverage and dep-weight now call enter_root(), which is why their
relative paths did not need rewriting one by one.
The Makefile derives REPO from MAKEFILE_LIST and resolves CARGO the same
way, so `make -C <repo> <target>` works from any directory with no
prefix.
make env-test is the positive control, and is in `make all`: every tool
runs from / with PATH=/usr/bin:/bin. Without it this fix could regress
silently and invalidate T05's measurement — the whole point of the
control loop.
dep-weight's "cargo not on PATH" error is kept rather than deleted. It
should now be unreachable, and --self-test asserts cargo_bin() resolves
unaided; a control that never fires is cheaper than a regression.
loop-lint failed on repo.py on its first run — a reporting tool with a
positive control but no --self-test entry point. Second time the gate
has caught work from its own pass within the hour.

Review of where token-priced turns did work a deterministic tool could
do. Method: classify every turn in both transcripts by the tool calls it
made. The classifier is committed in tools/cb-cost.py and emitted by
`make cost-mix`, so the baseline is reproducible and the same command
can later falsify the predictions.
mech environment setup 84 turns $15.33
mech ad-hoc text patching 75 turns $13.86
git 37 turns $13.85
mech hub task status 25 turns $ 7.46
mech orientation / inspect 49 turns $ 6.87
hub other 32 turns $ 6.22
mech ad-hoc transcript 39 turns $ 4.56
mech workplan status edit 21 turns $ 4.06
MECHANICAL (dedup) 290 turns $51.26 = 38% of pass
Largest category is `cd` and `export PATH` -- pure friction, and
dep-weight.py already patched it at the leaf, which is evidence it was
noticed and fixed in the wrong place. Second is heredocs string-patching
markdown, which is also the mechanism behind duplicated-fact drift, the
error class InnerLoop v1.2 names and cannot gate.
Explicitly NOT automated: git (37 turns, $13.85) is mostly commit
message authorship -- the highest-output turns in the corpus and the
project's reasoning record. Automating it would save money and destroy
what makes corrections cheap.
CB-WP-0004 implements five candidates and predicts $33-41 recovery
(25-30%), below the 38% measured share on purpose: some inspection and
patching is genuinely exploratory.
The control loop is the deliverable, not a formality. T05 tests three
things and must report all: did mechanical turns disappear, did they
RELOCATE into prose, and did quality hold. If mechanical turns fall and
prose rises by as much, the saving is zero and that is the result to
publish.
Also a self-indictment worth recording: every hub update_task_status in
this project carried hand-typed token estimates, in a repo whose central
finding is that estimated token counts are worthless. T02 fixes it by
reading measured values from cb-cost.

The 8k/10k per-task token budget was never referenced or enforced and
T08 blew past it silently. Replaced with a budget that can actually
fire.
The design constraint is the interesting part: per-task cost needs the
commit that CLOSES the task, so a per-task budget is unavoidably
retrospective -- it can only report a breach after the money is spent,
which is the dead-policy failure again. What IS observable mid-task is
spend since the last commit, because the transcript is append-live. So
the budget binds on the open remainder.
CB-01 budget = USD since the last commit, via `make cost-budget`
CB-02 soft $10.00 (state progress, decide), hard $22.00 (stop)
Calibrated on the 32 non-empty commit intervals of CB-WP-0001: p50
$1.40, p90 $9.36, max $10.80. Soft sits just below the observed maximum
-- it would have fired exactly once on the calibration pass. Hard is ~2x
the observed max, a value never reached in 32 intervals, so reaching it
means the session is doing something the data has no example of.
Both thresholds are set ABOVE every observed value, so they bind on
future work rather than ratifying present work -- the distinction T07
is about.
Stated limit: it is a command, not a daemon. An agent that never runs it
gets no signal, which is the dead-policy failure one level up. Mitigated
only by being free to run and on the one command surface.

41 rules classified executable / checkable / decorative, each tagged with
the failure class it catches. Counts: 11 executable, 22 checkable, 4
decorative (one of them dead policy).
Audit: history/260731-inner-loop-rule-audit.md
New tools/loop-lint.py makes 7 rules executable (tier declared, chaos
roll recorded, tier-L review trail, unmeasured-in-evidence, whole-file
loadability, reporting tools expose --self-test). It found three real
violations on its first run, none previously visible:
- specs/ArchitectureBlueprint.md was 543 lines against a ~400 limit
the loop has stated since v0.2 and never measured. Split at its own
section boundaries into Blueprint (1-8) + Runtime (9-15).
- tools/dep-weight.py and tools/rule-coverage.py had positive-control
logic and no --self-test, so nothing verified the control worked.
Adding rule-coverage's self-test exposed a latent instance of the exact
class this workplan is about: if the spec regex stopped matching, rules
was empty, missing was empty, and the tool exited 0 reporting "0/0" --
a silent pass, in the tool that reports our headline AM-1 number. Both
tools now assert they found something before reporting.
Two demotions applied in the spec rather than left implicit: "structured
over prose" is marked guidance (nothing can check it), and the 8k/10k
token budget is struck through and marked DEAD POLICY pointing at T05.
The audit's uncomfortable finding: rule 13 (re-derive inherited numbers)
has no mechanical form, is deliberately left decorative, and caught the
LARGEST error in CB-WP-0002. That is a counter-example to this
workplan's own hypothesis. "A rule that cannot be executed is not a
rule" is wrong as stated; the defensible version is that such a rule
cannot be relied on to fire, so it must not be the only defence for a
class that matters.
Class coverage: harness-does-nothing has five executable rules;
trusted-arithmetic has ZERO and produced the largest single error.

Collector per ADR-0003: enumerates every transcript including the
subagents/ tree, dedups by requestId, prices per model and per cache
TTL, attributes on (prev_commit, this_commit] intervals, and reconciles
to the cent or aborts.
The positive control caught a real defect on its very first run against
real data, which is the entire argument for writing it:
CA-02 assumed usage is identical across the lines of one requestId.
True in the main transcript (206/206 groups, verified twice — by the
survey and by the adversarial reviewer). FALSE in the subagents/
tree, where output_tokens is a running count: one response reads
5, 5, 195 across its three lines. First-wins scored it at 5.
So CA-02 now splits: input-side counters are charged once and must be
identical (assertion retained); output_tokens resolves to the max
(CA-02a). AC-9 pins the exact 5,5,195 case as a regression test.
The acceptance target moved again as a result, for the third time:
$248.46 -> $92.21 -> $92.87 -> $93.32. AC-1 was computed by the same
first-wins method the tool just disproved, so the tool failing its
target was the tool being correct. Target updated, not the tool.
Measured at the pin: $92.21 main + $1.11 subagent = $93.32, residual
$0.000000. 32.5% UNATTRIBUTED, reported as its own line per CA-10.
make cost / cost-test / cost-pin wired; cost-test added to `make all`
and to CI, where it gates the collector's assertions without needing
transcripts present.

The gates existed; CI ran half of them and tolerated the failure case.
- cb-sim no longer has a "tolerable" non-zero exit. An unregistered game
prefix is a failure, and a run in which nothing executed is a failure.
Previously CI carried `|| test $? -eq 2`, so renaming a scenario prefix
would have skipped every scenario while the pipeline stayed green.
Verified with a negative control.
- CI now runs make coverage (AM-1) and make dep-weight (AM-4), both
added after CI was written and neither enforced until now.
- dep-weight enforces its targets instead of only reporting them.
- CI lints the shipped-runtime configuration separately, so the feature
split cannot rot unnoticed.
- Dropped the stale `make deps` target, which still measured the retired
crate-count metric.
The positive-control rule is now executable: CI runs
`cargo bench -- --test`, which executes every benchmark once, so a
workload that stalls fails the build.
That step immediately found a fourth instance of the error class it was
written for. The committed replay benchmark was the broken version — an
earlier patch never applied, leaving a command sequence that omits
Resolve, so every round produced nothing and the log-building loop spun
forever. It had never run to completion; the reported AM-7 replay
numbers came from a probe test instead. Fixed, given the same positive
control as the round loop, and re-measured from the benchmark: 100k
events fold in 2.18ms (95% CI 2.14-2.23), against a 5s budget.
Evidence now reports confidence intervals rather than point estimates,
so the 3% regression rule in MetricsAndScenarios is enforceable.
The finding worth carrying: writing the positive-control rule into
InnerLoop v1.0 did not prevent the next instance. Making it a CI step
did.

Adopts both remediations from CB-EV-0001 §4 (maintainer decision).
Option A — serde_yaml is now optional behind cb-game-runtime's
`scenarios` feature. The scenario module, the ScenarioGame impl and the
string parsers behind it are cfg-gated; cb-sim opts in explicitly. Both
configurations compile and lint clean under -D warnings.
A trap worth recording: `default-features = false` on a *member*
dependency is silently ignored when the workspace dependency does not
specify it. The first attempt gated nothing while looking correct — the
build succeeded and cargo tree still showed all six YAML crates. Fixed
by setting it on the workspace dependency. This is the positive-control
failure mode in miniature: success was not evidence the change applied.
Retarget — AM-4 now measures third-party source under audit, split by
build configuration, replacing a crate count that was unreachable
without undoing K5/K7 and that does not compare across ecosystems.
Re-measured via the new `make dep-weight`, whose own positive control
refuses to report when any crate's source cannot be located:
shipped runtime 23 crates 246,250 lines target <=250,000 met
dev toolchain 29 crates 317,021 lines target <=350,000 met
own source 3,408 lines
Scenario tooling costs 70,771 lines a shipped game never compiles —
the split the single number was hiding.
Targets are set at current measurement plus headroom, so they bind on
future growth rather than retroactively passing what had failed.

make coverage compares the GR-rule IDs defined in specs/GroundRules.md
against the covers: lists in scenarios/ground/*.yaml. It exits 1 if a
scenario claims a rule the spec does not define, so coverage cannot be
inflated by an invented ID, and exits 2 while rules remain uncovered.
Current reading: 34/58 (58%). AM-1 requires 100%.
