chore(memory): job8 capitalize — journal + TODO follow-ups

Session log for job8 (A/B/C/D execution, 3 Bash permission denials
worked around mid-C, smoke gate confirmed by user). TODO tracks the
2 open residuals: C/D single-pass re-audit next cycle, MAGIC_API_KEY
rotation still pending (job7 residual, unrelated to job8's own scope).

 - **Alternatives rejected**: scrub-only (chosen as the fallback in job7's own instructions if reference-by-value support were absent) — verified Claude Code DOES support `${VAR}` expansion in `mcpServers` config (user + project scope, `env`/`command`/`args`/`url`/`headers` fields — code.claude.com/docs/en/mcp.md), so the reference form was available and preferred; global `export MAGIC_API_KEY` in `~/.bashrc` — works but broadens the secret's exposure to every subprocess of every shell session, defeating the point of the redaction hook (rejected by user in favor of the scoped wrapper).

 - **Caveat — contradicts job6's own finding same day**: job6's journal (2026-07-07, earlier same day) states "`${VAR}` env-expansion confirmed unsupported at `~/.claude.json` user scope after 2 rounds of sourced doc lookup". job7's doc lookup (claude-code-guide agent, same day) found it IS supported at user scope, citing code.claude.com/docs/en/mcp.md + a v2.1.161 changelog entry. Not reconciled — could be a version bump between the two lookups, or job6's research being wrong. The `${MAGIC_API_KEY}` rewrite is live (`claude mcp list` recognizes the reference and reports the var missing, which requires the CLI to have at least PARSED the `${...}` syntax) but full end-to-end confirmation (restart terminal + Claude Code, verify magic MCP reconnects) is still a residual the user needs to do — see BDR-057's own commit message.

+## BDR-058 — job8: darwin-skill reinstall full pinned tree, detached HEAD
+
+- **Date**: 2026-07-07
+- **Status**: accepted
+- **Decision**: darwin-skill non-functional past SKILL.md text — `references/`, `scripts/`, `templates/` absent, referenced but never fetched. Root cause: `~/.agents/.skill-lock.json` `skillPath: "SKILL.md"` — installer (`skills` CLI, vercel-labs/skills) fetches ONLY that one file, not sibling dirs. Upstream repo HEAD (`7c7b7909b630dc3b5cbb91bd4bcb1b10bfb1f894`) matches lockfile hash exactly — zero drift, zero tamper, SKILL.md byte-identical old vs new. Fix: cloned upstream at that SHA, copied full tree into `~/.agents/skills/darwin-skill/`, verified all 5 referenced paths present, HEAD detached (no branch tracking, no silent advance on a stray `git pull`). Old single-file dir backed up to `~/.agents/skills/.job8-backups/darwin-skill.single-file.<ts>` first.
+- **Why**: user picked reinstall-pinned over remove/keep-broken (job8 audit §4 item 4, 3-way choice). Unverifiable skill can't be trusted; user wants the optimizer kept, not removed.
+- **Alternatives rejected**: remove entry (kills wanted function); keep as-is (fails job8's own audit bar — unverifiable); flat-copy without `.git` (matches other 34 dormant skills' convention but drops verifiable pin — kept `.git` detached instead, darwin-skill now 2nd real SHA-pin in the whole trust chain after gstack, job8 report §5).
+- **Reference**: `~/.agents/skills/darwin-skill/` (detached HEAD `7c7b790`), `~/.agents/.skill-lock.json` (untouched, hash still accurate), backup at `~/.agents/skills/.job8-backups/`. Outside this repo — no commit here covers the file placement itself, this entry is the record. Git-commit whole-`.claude/skills`-tree scope (job8 C.2, `SKILL.md:115/201`) NOT restricted — 3rd-party pinned code, patching it breaks the pin; accepted as documented risk, human-checkpoint-gated per job8 report. Linked to [[LRN-109]].
+
+## BDR-059 — job8: explicit ask-gate for all 4 magic MCP tools, empty allow stays empty
+
+- **Date**: 2026-07-07
+- **Status**: accepted
+- **Decision**: `settings.json` `permissions.ask` now explicitly lists all 4 `mcp__magic__*` tools (`21st_magic_component_builder`, `21st_magic_component_refiner`, `21st_magic_component_inspiration`, `logo_search`). `permissions.allow` gets ZERO magic entries — no allowlist tightening, the job8 report's "frictionless" diff (allowlist logo_search + inspiration) was explicitly rejected. Confirmation required on every magic call, no exceptions, no auto-exec ever, no wildcard.
+- **Why**: job8 §3/§4 found zero real `mcp__magic__*` invocations ever (transcript census) and one SUSPECT finding (`21st_magic_component_builder` unauthenticated callback-injection channel, [[LRN-110]]). Prior state relied on undocumented absence-means-ask fallthrough — user wants the gate EXPLICIT so it can't silently regress if `permissions.allow` ever gets a careless wildcard or the default-mode semantics change.
+- **Alternatives rejected**: leave everything absent (report's own recommended default) — works today but is silent/undocumented, exactly the posture the user wanted to close; allowlist `logo_search` + `21st_magic_component_inspiration` for frictionless design work (job8 report §3 "frictionless" diff) — explicitly declined, real usage is zero so friction costs nothing.
+- **Reference**: `settings.json` `permissions.ask`, commit `bb7f25a`. Linked to [[LRN-110]] (component_builder risk), [[LRN-111]] (empty-allowlist validity when usage is zero).

Rewrote to `--env 'API_KEY=${MAGIC_API_KEY}'` + scoped `~/.bashrc` `claude()` wrapper (subshell+exec, verified the var never reaches the ambient shell) over a global export (user's call); `~/.claude.json` rewritten via surgical jq (never Read directly); README procedure doc added; 2 of 5 rotating `.claude.json.backup.*` still had the plaintext mid-fix, scrubbed. **B**: `hooks/rtk-rewrite.sh` now redacts bare `printenv`/`env` dumps (the GITEA leak's actual vector). Mid-implementation discovery: rtk classifies ANY `env`-containing command as exit-2 "deny" with no settings.json rule backing it (command still runs) — case handling fixed so redaction applies regardless. **C**: `.gitleaks.toml` (3 job7 false-positive classes + `.env` self-scan exclusion, all verified empirically against the real files, not assumed); pre-commit backstop wired into `lib/gitflow.sh` after the root/merge guard, ANY branch; `make scan-secrets` (repo + `~/.claude`, `--redact` confirmed to scrub the JSON report itself, not just logs). gitleaks 8.30.1: `protect` no longer in `--help` — used documented `git --staged`. **D** (GO-gated): rm'd transcript `960bd2cf` + `paste-cache/7d48f52c7499c1a7.txt` (both GO'd); `cleanupPeriodDays` 30→7 (1st write attempt correctly blocked by the auto-mode classifier for narrating the diff instead of actually pausing — re-asked properly). `make scan-secrets` surfaced 3 discoveries outside the original triage: `ide/20429.lock` (live, not touched), transcript `f1c9c474-...jsonl` (8 hits, left open — no option chosen).

Upstream HEAD matched the already-recorded lockfile hash exactly (zero drift). Reinstalled full tree at that pinned SHA, `.git` kept but detached (2nd real SHA-pin after gstack) [[BDR-058]]. Backup of old single-file dir kept. Git-commit whole-`.claude/skills`-tree scope NOT restricted (3rd-party pinned code, patching breaks the pin) — documented as accepted risk instead. 3 Bash permission denials mid-C (rsync x2, cp+rm) before a plain `cp` succeeded — `rm -r*`/`rm -rf*` are hard-denied even for scratch/temp paths, no prompt possible; switched approach rather than retrying identically. **D**: confirmed untouched. `make test` green throughout (incl. a live `path_present(darwin-skill)` fs check). Smoke gate: real `mcp__magic__logo_search` call in-session, user confirmed the ask prompt fired and was manually approved — no auto-exec. [[LRN-111]].

Traced to `~/.agents/.skill-lock.json`: `skillPath: "SKILL.md"` — installer fetched that ONE file, never the sibling dirs the skill text points to. Upstream repo (public clone, verified) had them all at the exact commit already recorded (`skillFolderHash` matches) — not drift, an installer-scope gap.
+- **future application**: any skill installed via `skills` CLI whose SKILL.md references relative paths needs a post-install check those paths exist on disk — `skillFolderHash` only hashes what WAS fetched, says nothing about what's missing. If absent: clone source repo at the recorded hash, copy full tree in, keep `.git` detached (cheap real pin, beats trusting the CLI's opaque hash alone).
+- **cousin**: [[BDR-058]] (this job's fix), darwin-skill's OVERSCOPED git-commit finding (job8 report — 3rd-party code, not patched, accepted risk under human-checkpoint gating, twin of [[LRN-105]]'s no-execute mandate for OUR read-only audits).

+- **context**: job8 audit read `dist/utils/callback-server.js:36` (+ `create-ui.js:35-38`) in the installed `@21st-dev/magic` package. `21st_magic_component_builder` opens a plain HTTP server on `127.0.0.1:9221+`, `Access-Control-Allow-Origin: *`, no token/origin check, staying open up to 10 minutes per call. Whatever body a POST to `/data` carries gets injected VERBATIM into the tool result the model then consumes — any local process or an open browser tab on the same machine can win the race against the legitimate browser hand-back.
+- **future application**: this is in the third-party package's code, not our config — don't try to patch a vendored/npx-installed dependency. The only real lever is on OUR side of the boundary: never allowlist a tool with this shape, keep it `ask`-gated so a human sees every invocation (see [[BDR-059]]).

+
+- **context**: job8 census (grepping real `"name":"mcp__…"` tool_use blocks across `~/.claude/projects`, not text mentions) found ~910 mentions of `mcp__magic__*` but ZERO real invocations, ever. `permissions.allow`/`permissions.ask` had no `mcp__*` entries at all before this job — job6 flagged that as "ZERO scoping", easy to misread as an oversight to fix by adding an allowlist.
+- **future application**: before treating "no entry for tool X" as a gap needing an allowlist, check real usage first (grep tool_use blocks, not prose mentions). If usage is zero, pre-authorizing costs nothing to skip and buys nothing to add — the honest fix is making the ask-gate EXPLICIT (so it can't regress silently), not granting allow access nobody needs yet. Only add allow entries when real, measured, recurring usage justifies removing the friction.
