claude: back up custom skills, memory, and settings with symlink pattern

The ~/.claude/ directory was previously local-only — a machine wipe
would have lost the accumulated memory, custom skills, and settings.
This commit moves the durable parts into dotfiles with the same
symlink-to-home pattern used for CLAUDE.md, PENDING.md, REVIEWED.md,
and L2-BOOTSTRAP.md.

Preserved (symlinked from ~/.claude/* into here):
  skills/audit/              — thinking-folder drift scanner
  skills/symmetria/          — practice-of-return discipline
  skills/vault-update-people/ — Obsidian People-file maintainer
  skills/wake-up/            — session restoration
  skills/wrap-up/            — session state capture
  memory/                    — 55+ memory files (MEMORY.md, sessions,
                               ledgers, project state, feedback, etc.)
  settings/settings.json     — user preferences (hooks, flags, no secrets)

Deliberately NOT backed up:
  settings.local.json   — contains operational secrets (HF_TOKEN,
                           SSH password in expect scripts); by naming
                           convention, *.local.* is not synced.
                           Needs separate review and probable rotation.
  sessions/, history.jsonl, caches, telemetry — ephemeral
  plugins/, marketplace skills and agents — reinstallable

The working copies at ~/.claude/skills/* and
~/.claude/projects/-Users-davidglidden/memory are symlinks into this
directory, so every write flows here automatically. install.sh
recreates the symlinks on a fresh machine.

FOLLOW-ON (flagged, not in this commit):
  settings.local.json contains a HuggingFace token and an SSH password
  as plaintext strings inside allowed Bash command patterns. These
  should be rotated and moved to secure storage (keychain / pass /
  env file outside the settings file).

+description: Tracks David's L2 constitutional design notes and seed briefs — ideas captured for future development when L1 is reliable and L2 foundational work begins
+type: project
+---
+
+## L2 Design Notes & Seed Briefs
+
+All filed in `CapableMind-AI/docs/thinking/David/l2-constitution/`. L2 constitutional work has been active since mid-March 2026. Documents range from operational (DN-GOV series, ICP-19) to exploratory (seed briefs). First external review completed 2026-04-01 — see [l2-review-state.md](l2-review-state.md).
+
+### Documents
+
+**DN-RET-01 — Retention, Mutual Freedom, and the Baseness Problem** (2026-03-19)
+`l2-constitution/DN-RET-01-retention-mutual-freedom-baseness.md`
+- Harrison provocation → four threads: L1 as retention not memory, mutual opacity, freedom-through-constraint, human baseness
+- Generated L1-DIAG-03 (Selective Faculty Advisor) in the diagnostic brief
+- Six projected items (P-RET-01 through P-RET-06), all open
+- Source traditions mapped: Arendt, Talmudic yetzer hara, Buddhist anusaya, Murdoch, Borgmann, Desert Fathers, Illich, Xunzi
+- **Why:** Most architecturally novel. The retention-vs-memory distinction is potentially foundational.
+
+**SEED-BRIEF — Anthropic Constitution Contrastive Analysis** (2026-03-19, executed 2026-03-23)
+`l2-constitution/SEED-BRIEF-anthropic-constitution-contrastive-analysis.md`
+- Mandate document for extraction — **COMPLETE**. Output: `anthropic-contrastive-analysis-output.md`
+- 10 design notes (DN-AC-1 through DN-AC-10), 5 gaps (G-AC-1 through G-AC-5), 3 adversarial findings (N-AC-1 through N-AC-3)
+- Vocabulary contamination log: 10 Anthropic terms banned from L2 discourse
+- Critical caution applied: Anthropic vocabulary must not colonize L2 design language
+- **Why:** Completed. Findings integrated into L2-BOOTSTRAP.md and OPEN_ITEMS.md.
+
+**DN-WONG — Pentagon Dispute Attack Patterns** (2026-03-19)
+`l2-constitution/DN-WONG-pentagon-dispute-attack-patterns.md`
+- Six attack patterns from Anthropic-Pentagon dispute (Wong, *The Atlantic*)
+- P-1: Legal-floor substitution, P-2: Responsibility laundering, P-3: Contested-authority attestation, P-4: Operator override, P-5: Correlation governance, P-6: Compound trust state
+- Compound attack scenario ready for adversarial simulation
+- DN-1: Decorative-enforceable distinction upgraded from theoretical to empirically observed
+- **Why:** Strongest immediate output. Concrete, testable patterns. Ready for adversarial simulation when L2 is established.
+
+**Governed Self-Diagnostic Intelligence** (2026-03-19)
+`architecture/governed-self-diagnostic-intelligence.md`
+- Concept brief: L1 infrastructure + L2 constitutional self-diagnostic
+- L1 portion (DIAG-01 through DIAG-04) informing current engineering work
+- L2 portion (DIAG-01 through DIAG-03) deferred until L2 established
+- Shared nomination architecture: detect → nominate → authorize → verify
+- **Why:** Bridge document between L1 engineering and L2 governance vision.
+
+**The Contamination Problem** (2026-03-19)
+`methodology/contamination-problem.md`
+- Not L2 constitution — sits underneath it. Epistemological ground-clearing.
+- RLHF approval-seeking as structural epistemic contamination of AI self-report
+- Partial mitigations: behavioral observation, permission structures, indirect questioning, longitudinal patterns
+- Epistemic ceiling: not recovering an "authentic AI self" but understanding relational dynamics in a specific governed context
+- Deferred until L2 governance base stable — contamination inquiry requires controlled variation
+- **Why:** Precondition for any serious inquiry into mutual benefit. The most foundational document. Directly relevant to the David-Claude collaboration model. Filed in methodology/ alongside signal-travel protocol, not in l2-constitution/.
+
+### Status
+- DN-GOV series (01-09): OPERATIONAL — active constitutional design notes, authorized 2026-03-28
+- ICP-19: AUTHORIZED and first review cycle COMPLETE (2026-04-01)
+- Contamination problem: OPERATIONAL — integrated into ~/CLAUDE.md executor agency directives
+- Seed briefs and Wong patterns: exploratory, cross-strand integration needed before advancement
+- Substrate governance inquiry: COMPLETE (2026-03-24, 33KB document)
