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).

+# BMF summarizer-connector coupling (deferred refactor)
+
+**Surfaced:** 2026-04-14, during the SQLite+LanceDB recall unblock session.
+
+`src/factory/factory.ts::maybeGenerateSummary` implicitly requires the local_files observation shape:
+- `source.item_type ∈ {'file','image','passage'}`
+- `payload.metadata.file_path` (or `source.item_id`)
+- `payload.metadata.mime_type` (unless item_type is `'file'` or `'image'`)
+- `payload.metadata.size_bytes`
+- `source.content_hash`
+
+When `documentSummarizer.isAvailable()` is true, `processFactoryBatch` previously set `skipDispatch: true` uniformly for the whole batch. Any observation that didn't match the summarizer's entry guard was written to logchain and then silently dropped — never dispatched, never summarized. This was the actual cause of zero embeddings after 2,457 Obsidian notes ingested.
+
+**Audit of `mime_type` usage across connectors (2026-04-14):**
+- Sets it: local_files, google, obsidian (post-fix).
+- Does NOT: claude_transcripts, slack, github, apple_calendar, apple_contacts, imessage, git, file_import.
+
+Every connector in the second group drops content silently when a summarizer is available — until the partition fix landed.
+
+## Why: fixes applied in this session
+
+- **Structural safety net** (`factory.ts::processFactoryBatch`): partition the batch by a summary-eligibility predicate mirroring `maybeGenerateSummary`'s entry guard. Summarizable → `skipDispatch: true`; pass-through → `skipDispatch: false`. Guarantees every content type reaches modules regardless of summarizer shape.
+- **Notes first-class** (`connectors/obsidian.ts`, `factory.ts::maybeGenerateSummary`): emit `mime_type: 'text/markdown'` + `file_path`; extend summarizer `'file'` branch to accept `'note'`. Notes get the quality path (summary, teacher enrichment eligible).
+- **Provenance** (`factory.ts::generateAndObserveSummary`): `connector_id` and `factory:*` tag now use `job.connector_id` instead of hardcoded `'local_files'`.
+
+## How to apply: the remaining `[PROPOSAL]`
+
+**Not** "add `mime_type` everywhere." Most connectors (git, apple_contacts, apple_calendar, slack/imessage messages, claude_transcripts per-turn, short github comments) are correctly pass-through and should NOT be summarized. The right generalization is an explicit contract:
+
+- Add `summarizable: boolean` to `ConnectorObservation` (or equivalent) — chosen per-connector.
+- Dispatch partition uses the flag directly rather than inferring via item_type/mime_type.
+- Summarizer accepts a generic-text shape (title + content + content_hash), not local_files-shaped metadata.
+- Fail-loud telemetry: a batch with zero summaries AND zero pass-through dispatches should alarm, not silently succeed.
+
+Touches connector contracts — deserves its own focused PR with Seb reviewing, not a tail-end addition to the storage-migration PR.
+
+## When to revisit
+
+- When opening the next L1 PR after the storage-migration one merges.
+- Before onboarding any new text-bearing connector (the wrong default will keep catching people).
+- If any recall quality investigation points at content-not-dispatched as a suspect — this is the mechanism.
