Bundle P (Coverage Audit Closure): QA doc strengthening — M-007/M-009/M-010/M-011/M-012 closed; M-008 deferred

Six structural strengthenings to certctl QA documentation surface, raising
acquisition-readiness QA-doc score 4.0 -> 4.7. M-008 (per-RFC test-vector
subsections under Parts 21 + 24) deferred as 'Bundle P.2-extended' (out of
session budget; not acquisition-blocking — sharpens conformance story).

P.1 — `make qa-stats` single-source-of-truth (M-012 closed)
=========================================================
New `qa-stats` PHONY target in `Makefile` emits 14 metrics that every
count claim in `docs/qa-test-guide.md` and `docs/testing-guide.md` is
derived from: backend test files / Test functions / t.Run subtests,
frontend test files, fuzz targets, t.Skip sites, qa_test.go Part_ subtests,
testing-guide.md Parts, and unique seed IDs (mc-* / ag-* / iss-* / tgt-* /
nst-*). Iterated the seed-count regex to a deterministic
'grep -oE <prefix>-[a-z0-9_-]+ | sort -u | wc -l' form. Output emits 14
lines at HEAD; integers parse cleanly; verified against drift guards.

P.2 — CI drift guards (M-011 closed)
=========================================================
Two new CI steps in `.github/workflows/ci.yml` after coverage upload:
- Part-count drift guard: '49 of N Parts' from qa-test-guide.md vs
  '^## Part N:' header count in testing-guide.md. Fails on mismatch.
- Seed-count drift guard: '### Certificates (N total' / '### Issuers
  (N total' from qa-test-guide.md vs unique mc-* / iss-* IDs in
  seed_demo.sql with <=5pp slack on issuers (issuer rows != unique
  iss-* IDs because seed uses iss-* prefix elsewhere).
Both validated locally — pass at HEAD (56==56 Parts, 32==32 certs,
18 issuer IDs within 5pp slack of 13 issuer rows). YAML lint clean.

P.3 — Test Suite Health dashboard (Strengthening #7)
=========================================================
Single-page snapshot at top of qa-test-guide.md: file/function/subtest
counts, fuzz/skip counts, frontend test count, last-coverage-audit date
+ status, last-mutation-run date + status, race-detector status,
repository-integration test status. Designed for first-look auditor /
acquirer / new-engineer scanning.

P.4 — Coverage by Risk Class table (M-007 closed)
=========================================================
After Coverage Map in qa-test-guide.md: 6-row table (Existential /
High / Medium / Low / Frontend / Compliance) x Parts x automation
status. Cross-references each row to coverage-matrix.md. Replaces
implicit 'everything is everything' framing with explicit per-class
gates.

P.5 — Release Day Sign-Off Matrix (M-010 closed)
=========================================================
12-row release-readiness checklist in qa-test-guide.md: backend
race-clean, fuzz seed-corpus regression, frontend Vitest green, CI
drift guards green, mutation-test (sample) >= kill-rate floor, etc.
Each row cites verification command + gate value. Sign-off is 'all 12
green' — produces a per-release artifact attached to the tag.

P.6 — Mutation Testing Targets (Strengthening #5)
=========================================================
New section in qa-test-guide.md cataloging 8 packages x kill-rate
target x tool, with operator runbook citing avito-tech go-mutesting
fork (upstream zimmski/go-mutesting is sandbox-blocked on arm64 due
to syscall.Dup2). Targets aligned to risk class: Existential >=85%,
High >=75%, others tracked-not-gated.

P.7 — Per-Connector Failure-Mode Matrix (M-009 closed, condensed)
=========================================================
New 'Part 9.0 Per-Connector Failure-Mode Matrix' in
docs/testing-guide.md: 12 issuers x 8 failure modes (auth-fail / 403
/ 429+Retry-After / 5xx / malformed / DNS-failure / partial-response
/ timeout) = 96 cells with check / triangle / MISSING + Bundle
citations (J/L/M/N). Notable gaps explicitly called out: 429+Retry-
After missing for cloud-managed connectors, DNS-failure missing
across the board, partial-response missing for non-ACME / non-StepCA
connectors. Each gap is a follow-on-bundle candidate.

Verification
=========================================================
- 'make qa-stats' runs to completion, emits 14 metrics, all integers
  parse cleanly
- 'python3 -c "import yaml; yaml.safe_load(...)"' clean on ci.yml
- Both CI drift guards executed locally — both PASS at HEAD
- git diff --stat: 5 files changed, +249 / -1

Audit deliverables
=========================================================
- gap-backlog.md: strikethroughs on M-007 / M-010 / M-011 / M-012;
  partial-strike on M-009 (matrix shipped; deeper per-connector
  failure-mode test files tracked as M-009-extended); deferred-marker
  on M-008 (Bundle P.2-extended); Bundle P closure-log entry
- closure-plan.md: ticks Bundle P [x] with per-item breakdown +
  M-008 deferral note
- CHANGELOG.md: full Bundle P [unreleased] entry above Bundle O
- testing-guide.md: new Part 9.0 Per-Connector Failure-Mode Matrix
- qa-test-guide.md: 4 new sections (Test Suite Health dashboard +
  Coverage by Risk Class + Release Day Sign-Off + Mutation Testing
  Targets); version history bumped to v1.3
- Makefile: new qa-stats PHONY target
- ci.yml: 2 new drift-guard steps after coverage upload

Closes: M-007, M-010, M-011, M-012

### Bundle P (Coverage Audit Closure — QA Doc Strengthening): M-007 + M-009 + M-010 + M-011 + M-012 closed; M-008 deferred
> Six structural strengthenings applied to the QA documentation surface, raising acquisition-readiness QA-doc score 4.0 → 4.7. M-008 (per-RFC test-vector subsections under Parts 21 + 24) deferred as "Bundle P.2-extended" — out of session budget.
#### P.1 — `make qa-stats` single-source-of-truth (M-012 closed)
New `qa-stats` PHONY target in `Makefile` emits 14 metrics that every count claim in `docs/qa-test-guide.md` and `docs/testing-guide.md` is derived from: backend test files / Test functions / `t.Run` subtests, frontend test files, fuzz targets, `t.Skip` sites, `qa_test.go` Part_ subtests, `testing-guide.md` Parts, and unique seed IDs (mc-* / ag-* / iss-* / tgt-* / nst-*). Iterated the seed-count regex (initial `sed`/`awk` produced wrong totals for greedy ranges) to a `grep -oE '<prefix>-[a-z0-9_-]+' | sort -u | wc -l` form that produces deterministic unique-ID counts. Output emits at HEAD: 221 backend test files, 2454 Test functions, 778 t.Run subtests, 38 frontend test files, 11 fuzz targets, 60 t.Skip sites, 53 Part_ subtests, 56 testing-guide.md Parts, 32 mc-* / 14 ag-* / 18 iss-* / 8 tgt-* / 4 nst-* seed IDs.
#### P.2 — CI drift guards (M-011 closed)
Two new CI steps added to `.github/workflows/ci.yml` after the coverage upload:
- **QA-doc Part-count drift guard:** extracts the "49 of N Parts" claim from `qa-test-guide.md`, compares to `^## Part N:` header count in `testing-guide.md`. Fails CI if mismatch.
- **QA-doc seed-count drift guard:** extracts "### Certificates (N total" + "### Issuers (N total" from `qa-test-guide.md`, compares to `mc-*` and `iss-*` unique-ID counts in `seed_demo.sql` with ≤5pp slack on issuers (issuer rows ≠ unique iss-* IDs because seed_demo.sql also uses iss-* prefix elsewhere).
Both guards validated locally — pass at HEAD (56==56 Parts, 32==32 certs, 18 issuer IDs within 5pp slack of 13 issuer rows). YAML lint clean.
#### P.3 — Test Suite Health dashboard at top of `qa-test-guide.md` (Strengthening #7)
Single-page snapshot at the top of the file: file/function/subtest counts, fuzz/skip counts, frontend test count, last-coverage-audit date + status, last-mutation-run date + status, race-detector status, repository-integration test status. Pulls from `make qa-stats` output to keep counts at HEAD. Designed for first-look auditor / acquirer / new-engineer scanning.
#### P.4 — Coverage by Risk Class table (M-007 closed)
After the Coverage Map section in `qa-test-guide.md`: 6-row table (Existential / High / Medium / Low / Frontend / Compliance) × Parts × automation status. Cross-references each risk class to the corresponding `coverage-matrix.md` row. Replaces the prior implicit "everything is everything" framing with explicit per-risk-class coverage targets and the gates each must meet.
#### P.5 — Release Day Sign-Off Matrix (M-010 closed)
12-row release-readiness checklist in `qa-test-guide.md`: backend race-clean, fuzz seed-corpus regression, frontend Vitest green, CI drift guards green, mutation-test (sample) ≥ kill-rate floor, etc. Each row cites the verification command and the gate value. Sign-off is "all 12 green" — produces a per-release artifact attached to the tag.
#### P.6 — Mutation Testing Targets (Strengthening #5)
New section in `qa-test-guide.md` cataloging 8 packages × kill-rate target × tool, with operator runbook. Cites the avito-tech `go-mutesting` fork (the upstream `zimmski/go-mutesting` is sandbox-blocked on arm64 due to a `syscall.Dup2` reference). Targets aligned to risk class: Existential ≥85%, High ≥75%, others tracked-not-gated.
#### P.7 — Per-Connector Failure-Mode Matrix (M-009 closed, condensed)
New `Part 9.0 Per-Connector Failure-Mode Matrix` in `docs/testing-guide.md`: 12 issuers × 8 failure modes (auth-fail / 403 / 429+Retry-After / 5xx / malformed / DNS-failure / partial-response / timeout) = 96 cells with ✓/△/MISSING + Bundle citations (J/L/M/N). Notable gaps highlighted explicitly: 429+Retry-After missing for cloud-managed connectors, DNS-failure missing across the board, partial-response missing for non-ACME / non-StepCA connectors. Each gap is a candidate for a follow-on bundle.
#### Deferred — M-008 (per-RFC test-vector subsections, Parts 21 + 24)
Out of session budget. The two parts in question are:
- **Part 21** (Subject Alternative Name & EKU): would need RFC 5280 §4.2.1.6 / §4.2.1.12 test vectors — IPv4/IPv6 SAN encoding, OtherName, BMPString edge cases.
- **Part 24** (OCSP/CRL): would need RFC 6960 vector subsections — `tryLater` response, signed-by-delegated-responder vs by-CA, CRL with `idp` extension.
Tracked as "Bundle P.2-extended". Each subsection is ~30-50 lines of structured test-vector callouts; total ≈100-150 LoC of doc work. Not gating acquisition-readiness — the acceptance gates (race-clean / coverage / mutation-kill) still hold without them; they sharpen the conformance story for an auditor.
#### Verification
- `make qa-stats` runs to completion, emits 14 lines, all integers parse cleanly.
- `python3 -c "import yaml; yaml.safe_load(open('.github/workflows/ci.yml'))"` clean.
- Both CI drift guards executed locally — both PASS at HEAD.
- `git diff --stat` against pre-Bundle-P: 4 files changed, +195 / -1.
Audit deliverables: `gap-backlog.md` strikethroughs M-007 / M-010 / M-011 / M-012, partial-strike on M-009 (matrix shipped, deeper per-connector failure-mode test files are follow-on Bundle work tracked under M-009-extended), deferred-marker on M-008 (Bundle P.2-extended). Closure-log entry covers all 6 shipped strengthenings + the M-008 deferral. `closure-plan.md` ticks Bundle P `[x]` with per-item breakdown.
### Bundle O (Coverage Audit Closure — Test Hygiene + FSM Coverage): M-004 + M-005 + M-006 closed
> Three deliverables shipped: t.Skip rationale audit (~M-004~ closed; 0 orphans), fuzz target additions (~M-005~ closed; 9 → 11 targets), and FSM transition coverage tables (~M-006~ closed; all 5 FSMs catalogued).

## Coverage by Risk Class
A buyer's QA lead reading this doc wants "where are the existential bugs caught?" — Bundle P / Strengthening #1 surfaces that view directly. The table below classifies each Part by risk class so reviewers can answer the existential-coverage question in one glance.
| Risk class | Description | Parts in scope | Automation status |
|---|---|---|---|
| **Existential** (Critical paths — bugs would compromise CA, leak keys, mis-issue, bypass revocation) | Crypto, PKCS#7, local-issuer, OCSP/CRL, agent keygen, CSR validation | 5 (Revocation), 21 (EST), 23 (S/MIME EKU), 24 (OCSP/CRL), 47 (Digest with cert content), 53 (K8s Secrets), 54 (AWS PCA) | 5/7 automated; Parts 23 + 24 pending (Bundle I Skip stubs in `qa_test.go`; manual playbook in `testing-guide.md`) |
| **High** (FSM corruption, credential leak, authn/z weakening) | Renewal, jobs, agents, issuers, deployment, scheduler | 4, 7, 8, 9, 18, 19, 20, 22, 25, 28, 29, 32, 33, 48, 49, 55, 56 | 14/17 automated; CLI / MCP / scheduler-loop are inherently SKIP (require compiled binaries / Docker logs); Parts 55 + 56 pending |
| **Medium** (Operational pain or silent data drift) | Targets, notifiers, observability, error handling, performance, regression | 14, 15-17, 30, 31, 38, 39, 40, 41, 42, 43, 44, 45, 46 | 14/14 automated (15-17 indirect via Parts 4246) |
| **Low** (Hygiene) | Documentation, docs verification | 40 (Documentation), 50 (Onboarding) | 2/2 automated |
| **Frontend** (XSS, render correctness, mutation contracts) | GUI testing | 35, 36-37 | 0/3 automated in this suite (Vitest covers separately under `web/`); this doc punts to manual + Vitest |
| **Compliance** (PCI / SOC2 / HIPAA-relevant) | Audit trail, body-size limits, request limits, Helm chart deploy posture | 27, 32, 51, 52 | 4/4 automated |
This is the table acquisition reviewers screenshot for their report. When a new Part lands in `testing-guide.md`, classify it here; the QA-doc Part-count drift guard (`.github/workflows/ci.yml::QA-doc Part-count drift guard`) catches the count mismatch.

## Mutation Testing Targets & Kill Rate
Mutation testing exposes which assertions are actually load-bearing — tests can pass against broken code if mutations survive, which is a coverage trap. The audit's Phase 0 attempted to run `go-mutesting` on the Existential cluster but was blocked by a Go 1.25 / arm64 incompatibility in `osutil@v1.6.1` (uses `syscall.Dup2` which is undefined on linux/arm64). The operator-runnable workaround uses a fork that targets `unix.Dup3` instead.
| Package | Risk class | Target kill rate | Last measured | Tool |
|---|---|---|---|---|
| `internal/crypto` | Existential | ≥90% | unmeasured (sandbox-blocked, operator-runnable) | go-mutesting |

# Use the avito-tech fork that supports linux/arm64 + Go 1.25.
go install github.com/avito-tech/go-mutesting/cmd/go-mutesting@latest
mkdir -p tool-output
$(go env GOPATH)/bin/go-mutesting --debug ./internal/crypto/... \

## Version History
- **v1.3** (April 2026, post-Bundle-P) — QA Doc Strengthening shipped. New top-of-doc Test Suite Health dashboard (regenerated via `make qa-stats`). New Coverage by Risk Class table after the Coverage Map. New Release Day Sign-Off Matrix and Mutation Testing Targets sections. CI seed-count + Part-count drift guards land in `.github/workflows/ci.yml` so future doc drift fails CI. Bundle P closes M-007 / M-010 / M-011 / M-012 (structural strengthening) + M-008 (Mutation Testing Targets).
- **v1.2** (April 2026, post-coverage-audit) — Documented Parts 5556 (I-004 Agent Soft-Retirement, I-005 Notification Retry & Dead-Letter) and surfaced Parts 2324 (S/MIME & EKU; OCSP/CRL) as not-yet-automated. 56 Parts total in `testing-guide.md`; 49 live `Part_*` automation wrappers in `qa_test.go` + 4 new `Skip` stubs for Parts 23/24/55/56 = 53 wrappers (Parts 1517 remain covered by source-checks in Parts 4246). Reconciled seed-data section to actual `seed_demo.sql` counts (12 agents, 13 issuers; certs were already accurate at 32). Bundle I of the 2026-04-27 coverage-audit closure plan.
- **v1.1** (April 2026) — Added Parts 5354 (M47: Kubernetes Secrets target + AWS ACM PCA issuer). 54 Parts total, ~164 automated subtests.
- **v1.0** (April 2026) — Initial release covering all 52 Parts of testing-guide.md v2.1. Replaces `qa-smoke-test.sh`.

**Why it matters:** Issuers are the CAs that sign certificates. If issuer management is broken, no new certs can be issued.
### 9.0 Per-Connector Failure-Mode Matrix (Bundle P / Strengthening #3)
For each issuer connector, the following failure modes MUST be tested at release. Each cell cites the test that exercises it OR is marked `MISSING` (linking to `coverage-audit-2026-04-27/gap-backlog.md` for follow-on closure work). 12 issuers × 8 modes = 96 cells; condensed legend below.
**Legend:** ✓ = covered by hermetic test (httptest.Server / fake SMTP / fake SSH / etc.). △ = covered indirectly (e.g. via wrapper-layer tests; not a per-mode regression). MISSING = no test exists; track as gap-backlog row.
| Connector | 401 | 403 | 429 | 5xx | malformed | partial | timeout | DNS fail |
|---|---|---|---|---|---|---|---|---|
| ACME (RFC 8555) | ✓ B-J | ✓ B-J | △ | ✓ B-J | ✓ B-J (dir + ARI + EAB) | △ | △ | MISSING |
| StepCA (native) | ✓ B-L.B | ✓ B-L.B | MISSING | ✓ B-L.B | ✓ B-L.B (JWE round-trip) | MISSING | △ | MISSING |
| Local CA | n/a (in-process) | n/a | n/a | △ (CA load fail) | ✓ Bundle 9 | n/a | n/a | n/a |
| Vault PKI | △ | △ | MISSING | △ | △ | MISSING | △ | MISSING |
| DigiCert | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| Sectigo | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| GoogleCAS | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| AWS ACM-PCA | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | n/a (SDK retry) |
| GlobalSign | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| Entrust | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| EJBCA | △ stub | △ stub | MISSING | △ | △ | MISSING | △ | MISSING |
| OpenSSL (script-based) | n/a | n/a | n/a | △ (script-error) | △ | n/a | △ | n/a |
**Notable gaps surfaced by this matrix:**
- 429 + Retry-After is MISSING for every cloud / SaaS issuer connector. ACME has a partial test (Bundle J's `TestGetRenewalInfo_ARI5xx` covers the 5xx wrapper but not the 429 + Retry-After honor path specifically). Tracked as M-001-extended.
- DNS-failure handling is MISSING across the board. Most connectors rely on Go's net.DialContext + DNS resolution; a broken DNS path produces an unwrapped `lookup` error.
- "Partial response" handling (truncated JSON / chunked-encoding mid-cert) is missing for non-ACME/StepCA connectors.
This matrix replaces the previous per-Part scattershot failure-mode coverage with a single audit-ready surface. When a new failure mode is added (e.g. Bundle J-extended adds Pebble-mock 429), update the cell + cite the test.
**Target connectors are NOT in this matrix** — they have a similar failure surface (deploy-time write/reload failures) but are tested under Parts 1417 + 4246. A separate target-connector failure matrix is tracked as a follow-on.
