docs(qa-guide): §3 routes mutation validation to mutation-probe, not a hand loop#337thedavidmeister wants to merge 3 commits into
Conversation
…a hand loop Closes #336 §3 was a complete self-contained recipe — "apply ONE targeted mutation … confirm the test fails, restore" — and never named `mutation-probe`, the bin the `adversarial-mutation-test` skill runs at its step 3. campaign-prompt.txt step 4 already says to INVOKE the skill rather than hand-copy its rules, but §3 wins for anyone reading the guide alone, and §8's mandatory `Mutations applied` line sends every producer back to it. So agents wrote their own harness every run. The tool is now the route, with the runnable command, `--help` as the manual for file format / verdicts / exit codes, and the four integrity properties stated as the REASON: green non-empty baseline, proof from the suite's own tally that it RAN (NO-RUN is not a pass), an exactly-once target, and a byte-exact restore re-checked before the next mutant. A hand loop can assert all four and prove none. The two duties the bin cannot discharge — commit before the first probe, keep targets out of test code — are named as the producer's. §8's `Mutations applied` line now says its content is TRANSCRIBED from the probe's verdicts, and step 3c(ii)'s "(break the covered line → the assertion FAILS → restore → PASSES)" points at the same probe. The hand-roll is a prohibition, not an omission: a rule merely deleted is a rule the next edit reinvents, which is why the retirement is pinned by a test the way `the_producer_prompt_routes_screenshots_to_this_subcommand` pins #251's. The guide is charged to the prompt cap because campaign-prompt.txt names it, and it grows 1,077 bytes net of step 3c(ii)'s cut. Cap tracks the measurement: 154969.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the producer duties outside the probe scope.
The test does not require QA-GUIDE.md to instruct producers to commit before probing or to keep mutation targets out of test code. A future edit can remove either required instruction while this test still passes. Add explicit assertions for both duties.

`pre-commit run --all-files` re-wrapped §3's integrity paragraph, which is the formatter's call and stands. The lesson is the test's: two of its phrases landed mid-line before the wrap and spanned a line break after it, so the assertions were reading column width rather than the rule. It now matches against whitespace-collapsed text, where a rule that wraps is the same rule. Byte count is unchanged by the re-wrap (6,946), so the cap stays at 154969.

The cap is not raised. 153919 stands; the charged text comes under it. §3's new rule is that a tool's method routes to the tool — "`mutation-probe --help` is the manual ... rather than a snapshot of them here, which is what goes stale". Applied to the guide itself, which is what paid for the raise: - §3: the "Two duties stay yours" sentence and the SURVIVED paragraph are the `adversarial-mutation-test` skill's per-unit loop steps 3 and 4, near verbatim, in a section whose first sentence already routes to that skill and whose second paragraph already routes verdicts to `--help`. The punchline a test that survives its own mutation is decoration stays; the recipe goes. - §1: the baseline rule is the skill's step 2 and the bin ABORTS on a red, silent or zero-test baseline — which §3 states. One line is left. - §4: the method (derive from spec, don't mirror, prefer asymmetric invariants) is the skill's adversarial pass 0-3 and its own principles. What the skill does not carry is this org's precedents, so those are all that is left. - §8: the two closing paragraphs restated `open_pr`'s and `repair-qa-block`'s own refusal behaviour, both of which campaign-prompt.txt already carries in full. The gates and the retrofit's name stay; their manuals go to `--help`. The anti-fabrication rule survives above it, stronger: a mutation nothing scored is not evidence. Untouched: §3's routing and the integrity properties the pin test asserts, the §8 template line `require-qa-block` matches byte-for-byte, and §2's core rule. prompt cap: 153764 / 153919 — 155 bytes of headroom, against 10 before the change that raised it.

Closes #336
QA-GUIDE.md§3 taught a hand-rolled mutation loop — "apply ONE targeted mutation tothe line it claims to cover … confirm the test fails, restore" — and never named
mutation-probe, the bin theadversarial-mutation-testskill runs at its step 3.campaign-prompt.txtstep 4 already says to INVOKE the skill rather than hand-copy itsrules, but §3 read as a complete self-contained recipe, so it won for anyone reading the
guide alone — including for §8's mandatory
Mutations appliedline, which sends everyproducer back to §3 to produce its evidence.
What changes
§3 is the tool's route now. It gives the runnable command
(
nix run github:rainlanguage/adversarial-mutation-test#mutation-probe -- mutants.toml),sends file format / verdicts / exit codes to
mutation-probe --helprather than restatinga snapshot of them, and states the four integrity properties as the REASON the tool is the
route rather than a preference — a green non-empty baseline (a red, silent or zero-test one
aborts before any probe), proof from the suite's own tally that it RAN (a crash or compile
error is
NO-RUN, never a pass), a target that occurs EXACTLY once in its file, and abyte-exact restore verified before the next mutant. A hand loop can assert all four and
prove none. The two duties the bin cannot discharge stay named as the producer's: commit
before the first probe, and keep targets out of test code.
The hand-roll is retired as a PROHIBITION, not an omission ("Do NOT hand-roll an
edit-run-restore loop") — a rule merely deleted is a rule the next edit reinvents.
§8's
Mutations appliedline now says its content is TRANSCRIBED from the probe'sverdicts; the template line itself is untouched, so the
require-qa-blockpredicate and therefusal's printed template still match byte for byte.
The other place teaching the hand-roll was
campaign-prompt.txtstep 3c(ii)'s"mutation-validate per step 4 (break the covered line → the assertion FAILS → restore →
PASSES)", which now points at the same probe. Those are the only two: a sweep of the tree
for mutation-loop prose found the guide, that parenthetical, and nothing else —
plugins/rain-repo-conventionsrecords only that the §8 gate exists and defers content tothis guide, and
review-prompt.txtnames the block without teaching how to produce it.Pinned by a test, the way
the_producer_prompt_routes_screenshots_to_this_subcommandpins #251's hand-roll retirement: the recipe must be GONE from both files AND the tool
present as the route, asserted both ways round.
The prompt cap
QA-GUIDE.mdis charged to the**/*prompt*cap becausecampaign-prompt.txtnames itoutside a code span. The guide grows 1,077 bytes and step 3c(ii)'s cut returns 17, so the
measurement moves 153,909 → 154,969 and the cap tracks it exactly (
rainix-static prompt-caprun locally, both before and after). The reason for the raise is the integrityparagraph: it is what stops a reader deciding the tool is optional, and the run it saves —
one hand-built harness per producer run — costs far more than 1,060 bytes of window.
QA
settings_tests::the_qa_guide_routes_mutation_validation_to_the_bundled_probe— unchanged by this commit and still the pin (its fails-on-base run is recorded above and still stands). This commit is a byte-cut toQA-GUIDE.mdprose plus the cap restore, so its OWN discriminating gate is theprompt capjob:rainix-static prompt-cap --paths '**/*prompt*' --cap 153919FAILS on the pre-change tree 1ab547f ("the prompt files matching **/prompt load 154969 bytes — 1050 over the 153919-byte cap") and PASSES on ee9a6f3 ("prompt-cap: clean — 153764 bytes of prompt (cap 153919)").cargo fmt --check,cargo clippy --workspace --all-targets -- -D warnings,cargo test --workspace(1585 passed, 0 failed) andpre-commit run --all-files(11 hooks, all Passed) are green on ee9a6f3.mutation-probeon ee9a6f3, baseline green (1 passed), tree byte-exact after. First pass8/9 killed; survived: 0; no-run: 0; harness errors: 1— M06 was a HARNESS-ERROR (target occurs 0x) because the phrase wraps mid-line in the raw file; re-probed with--only M06against the wrapped target:1/1 killed; survived: 0; no-run: 0; harness errors: 0, exit 0. Each mutant → the killing test is that same pin test. M01nix run …#mutation-probe -- mutants.toml→ broken flake attr#mutation-prober; M02 "mutation-probe --helpis the manual" → "mutation-probeis the manual"; M03 "A red, silent or zero-test baseline aborts before any probe" → "A baseline is checked"; M04 "is NO-RUN and never a pass" → "is a pass"; M05 "each target must occur EXACTLY once in its file" → "each target is found in its file"; M06 "every restore is verified byte-exact before the next mutant" → "byte-exact" dropped; M07 "Do NOT hand-roll an edit-run-restore loop" → "Prefer the bin"; M08 "TRANSCRIBED from the probe's verdicts" → "recalled from the probe's verdicts"; M09 the retired hand recipe ("apply ONE targeted mutation to the line it claims to cover, confirm the test fails, restore") re-inserted after "decoration."rainix-static prompt-cap's own printed measurement at each sha, not an estimate. WHICH prose may go is derived from the skill and the bins rather than from this guide:adversarial-mutation-testSKILL.md 0.34.0 carries §1's baseline rule (per-unit loop step 2), §3's "Two duties stay yours" sentence (step 3, near verbatim) and its SURVIVED paragraph (step 4, near verbatim), and §4's method (adversarial pass 0-3 + Principles);mutation-probe --helpowns the verdicts §3 was explaining; andcampaign-prompt.txtsteps 3 and 4 carry §8's removedopen_pr/repair-qa-blockmanuals in full. §3's own new rule — route to the tool's manual rather than snapshot it — is the oracle for cutting §8's snapshot of the other two tools' manuals.Mutations appliedline pointed at the same place, (c) anything else in the repo teaching the hand-roll — covered a, b, c and unchanged by this commit ((c) iscampaign-prompt.txtstep 3c(ii));Closesrather thanRefsbecause the issue's ask is fully covered. This commit adds NO scope: it restores the cap this PR had raised (153919 stands — the standing ruling is that it is never raised) and pays for §3/§8's new text by cutting 1,205 bytes ofQA-GUIDE.mdprose the skill and the bins already own (6,946 → 5,741 bytes; charged total 154,969 → 153,764 against the 153,919 cap — 155 bytes of headroom where the pre-PR tree had 10). §3's routing and the four integrity properties the pin test asserts, §8's template line thatrequire-qa-blockmatches byte-for-byte, and §2's core rule are all untouched. NOT covered, and out of this subcommand's reach: the body's "## The prompt cap" section above still argues for the 154,969 raise and is now superseded —repair-qa-blockedits only the## QAsection by design andgh pr editis forbidden, so it is flagged in a PR comment for a human to strike.Summary by CodeRabbit
