 ### BDR-078 — ctx7 coverage: central fast-libs list + once-per-session reminder hook; every code path covered [accepted] (2026-07-20)
 Refines BDR-053 (single surface). Audit 2026-07-20: coverage PARTIAL — find-docs fired on user doc-questions only; ship-feature 0c / init-project 5c pre-fetched; /feat //bugfix executors + ad-hoc coding NEVER consulted ctx7; fast-libs list hardcoded 3× (drift risk). 4 closures shipped: (a) find-docs description += BEFORE-writing-code trigger (fast-moving lib, even without doc question, unless fresh cache) + cache-first rule in body (tee fetched docs to .ctx7-cache/); (b) feater+bugfixer briefs += fast-lib docs rule — read fresh `.ctx7-cache/<lib>*.md`, else `npx ctx7@latest` fetch max 2 topics, else `ctx7 cache miss: <lib>` in NOTES + proceed (executors lack Skill tool → Bash path); (c) hooks/ctx7-reminder.sh UserPromptSubmit — ONE fire/session (sentinel on session_id), only when project manifest carries fast-libs; reports cache state; skips <task-notification> turns; always exit 0; (d) lib/fast-libs.sh = SINGLE SOURCE (detect / cache-status verbs, JS package.json anchored full-key match + Python requirements/pyproject, 7-day freshness, LC_ALL=C sort locale-independent) consumed by hook + 3 pipeline skills + 2 briefs. 2nd session surface DELIBERATE, not a BDR-053 reversal: 053 killed a 490-tok ALWAYS-ON rule duplicate; hook costs ~0 quiet, 1 line once when fast-libs present. Alternatives rejected: PreToolUse Edit/Write gate (fires per-edit = noise); description-only fix (probabilistic, executors unreachable). Tests: lib/tests/fast-libs.test.sh 11 checks (anchored/near-miss/py/none, cache fresh/stale/missing, hook fire/sentinel/quiet×2); shellcheck + full make test green. Branch feature/ctx7-coverage, unmerged (human gate).
 Amendment (same session): skills/find-docs = machine-owned dist (gitignored, ctx7 regenerates on fresh clone) → durable copy of closure (a) lives in install-plugins.sh STEP ctx7 (idempotent grep-guarded python patch, fixture-verified); live SKILL.md carries the same edit uncommitted by design.

+### BDR-079 — profile `set` symmetric on managed externals + MCPs [accepted] (2026-07-20)
+Audit (user ask "profile toggles externals both ways?"): ASYMMETRIC. Enable side OK — gstack on-demand from submodule when pack off (shared `skills-disabled/gstack__*` convention with toggle-external.sh, interoperable), externals restored from parked, magic delegated to toggle-external. Disable side MISSING: `cmd_set` trimmed only gstack + MANAGED_PLUGINS → `set backend` left emil/frontend-design/design-motion/impeccable active + magic registered; SKILL.md claimed both-ways toggle (true only at enable). Shipped: (1) `MANAGED_EXTERNALS` (emil-design-eng, frontend-design, design-motion-principles, impeccable = exact union of profile `external` usage; darwin-skill excluded — not task-type-driven) + `MANAGED_MCPS` (magic) allowlists, same doctrine as MANAGED_PLUGINS; (2) cmd_set refactored to 4 trim helpers (`disable_{gstack,plugins,externals,mcps}_not_in`) — symmetric, nothing outside allowlists ever auto-touched; (3) enable_skill external += from-source fallback (`ln -sf skills-external/<name>`, mirrors toggle-external) — closes the "missing symlink" warn; (4) stale usage() NOTE ("NOT toggled automatically") + SKILL.md fixed. Hermetic test profile-set-managed.test.sh 16 checks: fixture repo (both *_REPO_OVERRIDE), fake `claude` shim on PATH logging calls + flat-file MCP registry — gstack on-demand, external from-source, park/restore round-trip, magic add/remove calls, non-managed untouched. shellcheck + make test green.

+- **Profile switches now toggle external packs and MCPs both ways (BDR-079)** — `profile.sh set` was asymmetric: it enabled what a profile listed (including gstack skills on demand when the whole pack is off, and the `magic` MCP) but never disabled the managed leftovers, so `set backend` after design work kept emil-design-eng / frontend-design / design-motion-principles / impeccable active and magic registered. `set` now trims managed externals (`MANAGED_EXTERNALS`) and managed MCPs (`MANAGED_MCPS`, delegated to `toggle-external.sh`) not listed in the profile — same allowlist doctrine as `MANAGED_PLUGINS`, nothing outside the allowlists is ever auto-touched (darwin-skill stays manual). Also: an `external` entry whose symlink never existed is now created from `skills-external/` (mirroring toggle-external's from-source path), and the stale "NOT toggled automatically" note in `profile.sh` usage was corrected. Covered by a hermetic 16-check test (`lib/tests/profile-set-managed.test.sh`) with a fake `claude` shim.

 **Managed plugins** that `set` may disable when not in profile:

 `pr-review-toolkit@claude-code-plugins`. Other plugins are never auto-toggled.
+**Managed externals** (`emil-design-eng`, `frontend-design`,
+`design-motion-principles`, `impeccable`) and **managed MCPs** (`magic`)
+follow the same symmetry (BDR-079): `set` enables them when the profile
+lists them (from parked state, or from `skills-external/` if the symlink
+never existed) and parks/unregisters them when it does not — e.g. `set
+backend` after design work turns emil and magic off. `darwin-skill` and any
+other unlisted external are never auto-touched. gstack works the same
+all the way down: a profile listing gstack skills while the whole pack is
+off (via `toggle-external.sh`) re-enables JUST those skills on demand.

   update-check, learnings — script doesn't touch that infra. Disabled skills
   are just hidden from Claude Code's scanner; the gstack repo stays installed.
 - Profile changes DO toggle the managed Claude Code plugins (ui-ux-pro-max,
-  plugin-dev, pr-review-toolkit) and the `magic` MCP — see the Mechanism table
+  plugin-dev, pr-review-toolkit), the managed external packs (emil-design-eng,
-  above (BDR-008). Anything outside that managed set stays manual:
+  frontend-design, design-motion-principles, impeccable) and the `magic` MCP —
-  `claude plugin enable|disable`, `claude mcp add|remove`.
+  in BOTH directions: `set` enables what the profile lists and disables the
+  managed leftovers it doesn't (BDR-008, BDR-079). Anything outside those
+  allowlists stays manual: `claude plugin enable|disable`, `claude mcp
+  add|remove`.
 - `set` is destructive in the sense that it disables non-listed gstack skills.
   Use `apply` if the user wants additive behavior.
