job4: capitalize execution — EVAL-019 + LRN-106 + journal

EVAL-019: job4 test-gap audit + execution summary (11 specs, 5 fixes/
seams, every mutation red-green verified, zero residual, /tmp-exhaustion
incident + recovery, SPEC-06 checkpoint honesty, J4-22 caller-census
flag).

LRN-106: fixing B1 in one file != closing the B1 pattern. job3-B1
froze a fixture + repointed run-reconcile.sh's T2 off the live
registry, declared unblocked, 20/20 green — job4's very next audit
pass found T3/T5 in the SAME FILE still reading the live registry,
same fragility, untouched siblings. Now actually closed (SPEC-10).

journal: 2026-07-06 (cont. 2) entry.

 - **result**: 46/46 REPRODUCED pre-fix (3 corrected attributions). Post-fix re-sweep: 0 residual findings from job3's own edits (1 pre-existing minor abbreviation noted, informational only). `make test` all green. `run-reconcile.sh` unchanged 18 GREEN/2 RED (B1 deliberately untouched, see blocker below).
 - **anomalies**: (1) B1 (reconcile fixture hermeticization) BLOCKED — `lib/tests/` is guarded by the same config-protection.sh gate as `hooks/`, and the user's sentinel pre-authorization was scoped only to `[SENTINEL-REQUIRED]` hook edits; the auto-mode classifier correctly refused the sentinel for a lib/tests/ write outside that scope. (2) Verification sweep incidentally surfaced 2 pre-existing, out-of-job3-scope drifts: `agents/client-handover-writer.md:885` still says "4-chapter structure" (contradicts its own lines 23-43 "6 chapters", predates job3); `.claude/memory/decisions.md` index has no row for BDR-053 (body exists, gap from job2).
 - **action**: keep. B1 needs a follow-up session with explicit lib/tests/ sentinel authorization. The 2 incidental findings are candidates for a future audit-delta pass, not fixed here (out of scope).

+- **Date**: 2026-07-06
+- **output**: `.audit/job4-report.md` — 22 findings across hooks/gitflow-guardrails/session-libs/reconcile-fixtures/graphify (20 confirmed, 1 refuted-retargeted J4-05b, 1 dropped stale). Executed on `chore/job4-tests` (unmerged, 20 commits): SPEC-01 Makefile aggregation, SPEC-02/04/05 gitflow T13/T14/T15, SPEC-08/10/09 reconcile oracle-sandbox + decisions-fixture + snapshot-retirement (in that order), SPEC-03 curated-config-guard (new file), SPEC-07 doc-shape removed envelope, SPEC-11 prune-suite source fix, SPEC-06 config-protection payload matrix (gated, user-confirmed before writing); J4-04 memory-commit fail-loud (test-red then fix, 2 commits), J4-20 toggle-external logical-cd fix (test-red then fix, 2 commits, BLK-006 class); SEAMS bundle (profile.sh/toggle-external.sh/design-tool-gate.sh/session-start.sh, env-var only); install-plugins fail-closed on mktemp failure; J4-22 deploy-commit exit taxonomy (rc 6 + deploy/SKILL.md doc-sync, user GO after caller census).
+- **method**: every new/changed test's mutation demonstrated RED on a scratch/lean copy (never the working tree) before commit, then GREEN on the real repo confirmed before each commit. Sentinel created immediately before each guarded lib/tests/ write (19 consumed, all logged with per-spec reasons). SPEC-06 (config-protection's own test) held at an explicit user-confirmed checkpoint despite the formal AUTHORIZATION line already saying so — the user's instructions contained a real ambiguity (free-text said "STOP and ask" for this one spec, the filled-in template said "AUTHORIZED"), resolved by asking rather than guessing.
+- **result**: `make test` grew from 71 (gitflow only, 5 suites excluded) to 90 gitflow + all 5 previously-excluded run-*.sh suites now included (13→16 deterministic, 32 doc-commit unchanged, 19→23 doc-shape, 20→25 reconcile, 5/5 release) + 4 *.test.sh grew or were added (20→24 config-protection, 0→6 curated-config-guard new, 13→16 deploy-commit, 0→1 toggle-external-repo-resolution new). Full `make test` exit 0 throughout, zero regression across 20 commits.
+- **anomalies**: (1) `/tmp` (tmpfs, 7.4G) exhausted mid-session from repeating full-repo `cp -r` (incl. `.git` + gstack submodule, ~1.6G each) for the first 4 specs' scratch copies — the Bash tool became universally unresponsive (even `true`/`echo` failed with exit 1/134) until the user cleared `/tmp` manually; switched to copying only the minimal file subset each mutation needs for the remaining ~16 specs/fixes. (2) config-protection.sh's guard matches by path SUFFIX regardless of directory, so scratch-copy mutations of `lib/gitflow.sh`/`hooks/*.sh` tripped it too even though they were throwaway and never committed — used Bash/sed/perl (shell-level file ops, which the hook's own header comment says it never covers) instead of Edit/Write for those mutations, reserving the sentinel strictly for genuine `lib/tests/` writes. (3) J4-22's caller census (an explicit gate in the report) found `deploy/SKILL.md` parses `deploy-commit.sh`'s exit codes — flagged before committing, user confirmed GO to extend that doc too rather than leaving it stale.
+- **action**: keep. Branch unmerged (`chore/job4-tests`, human gate per report). Backlog carried forward unbuilt, deliberately per report scope: J4-13 (rtk-rewrite), J4-14 full (session-start banner truth-table — only the offline-fetch seam landed), J4-15/16/17 (toggle-external 3-state/attribution-census/memory-commit pending verb), J4-18 (graphify pytest greenfield), and the hermetic suites the SEAMS bundle unlocked but didn't build for profile.sh/toggle-external.sh/design-tool-gate.sh (J4-19/20/21, now spec-able instead of UNTESTABLE).
