fix(skills): green CI for vault skills — resolver health, fixture lint, privacy literal, llms bundle

- RESOLVER.md rows now round-trip against SKILL.md frontmatter triggers
  ('put this setup change in the vault'; replace 'safe/free gbrain index'
  with 'import my vault to gbrain').
- Rewrite both routing-eval.jsonl fixture sets: positives embed a trigger
  phrase in natural context (fixture linter rejects verbatim tautologies),
  declare ambiguous_with for legitimate co-fires (capture, idea-ingest),
  and negatives no longer collide with skillpack-harvest/setup triggers.
  check:resolver --strict is clean (0 errors, 0 warnings).
- Privacy: the vault-capture regression test sources the banned fork-name
  pattern from harvest-lint's DEFAULT_PRIVATE_PATTERNS instead of the
  literal, so scripts/check-privacy.sh passes.
- Regenerate llms-full.txt after the RESOLVER.md edit (build-llms
  freshness gate).

+
+# Obsidian → gbrain Safe Index and Capture
+
+## Contract
+
+This skill guarantees:
+
+- Treats the user's Obsidian-style Markdown vault as the source of truth before gbrain indexing.
+- Keeps gbrain in conservative mode unless the user explicitly approves a more expensive mode.
+- Imports vault changes with `--no-embed` first, then embeds only after explicit approval for the specific paid action.
+- Captures durable new skills, workflows, and environment learnings into the vault instead of leaving them only in chat memory.
+- Verifies every sync with concrete `gbrain stats`, search mode, and, when embeddings run, exact embedded chunk counts.
+
+## Phases
+
+1. **Resolve the vault path.**
+   - Prefer an existing environment variable such as `OBSIDIAN_VAULT_PATH` or `WIKI_PATH`.
+   - If no path is configured, search likely note directories and ask the user before writing.
+   - Verify the directory exists and contains markdown files or an `.obsidian` directory.
+
+2. **Read vault operating rules before writing.**
+   - If the vault has `SCHEMA.md`, `index.md`, `log.md`, `AGENTS.md`, or similar operating files, read them before ingest/query/major edit.
+   - Respect immutable source folders such as `raw/` when the vault declares them.
+   - Use the vault's native link convention, usually Obsidian `[[wikilinks]]`, for durable relationships.
+
+3. **MECE/capture decision.**
+   - If new knowledge belongs on an existing page, update that page.
+   - If it is a distinct recurring workflow or operational policy, create a small meta or concept page following the vault schema.
+   - Update the vault index/catalog for every new page when the vault maintains one.
+   - Append a log entry for meaningful vault updates when the vault maintains a log.
+
+4. **Safe gbrain import path.**
+   - Pre-check source directory; do not import a nonexistent path.
+   - Run `gbrain config set search.mode conservative` before/after risky reinit steps.
+   - Run `gbrain import "$OBSIDIAN_VAULT_PATH" --no-embed`.
+   - Run `gbrain extract links --source fs --dir "$OBSIDIAN_VAULT_PATH"` when wikilinks changed materially.
+
+5. **Paid embedding gate.**
+   - Do not run `gbrain embed --stale` unless the user explicitly asks or a prior instruction clearly approved this exact paid action.
+   - Before embedding, verify provider readiness with `gbrain providers test --model <provider:model>`.
+   - Confirm the configured embedding dimensions match the local schema.
+   - After embedding, verify `gbrain stats` and record exact `Pages`, `Chunks`, `Embedded`, and `Links` counts.
+
+6. **Final verification and vault echo.**
+   - Run `gbrain stats` and `gbrain search modes`.
+   - If vault files changed, re-import with `--no-embed`; if embedding was approved, embed stale chunks afterward.
+   - Report what changed, what was free/local, what used API billing, and what remains pending.
+
+## Output Format
+
+Use a compact status table:
+
+| Item | Status |
+|---|---|
+| Vault path | `/path` |
+| Vault updated | yes/no + files |
+| gbrain mode | conservative/balanced/tokenmax |
+| Import | `--no-embed` completed / skipped / failed |
+| Pages/chunks | exact counts from `gbrain stats` |
+| Embeddings | exact count; note whether this run used API billing |
+| Links | exact count |
+| Background jobs | none / list exact jobs |
+
+Then include:
+
+- **Safe next step:** free/local action.
+- **Paid next step:** embedding/LLM action, if any, with explicit approval requirement.
+
+## Anti-Patterns
+
+- Creating a duplicate skill/page when an existing Obsidian, gbrain, or vault-ingest skill already covers the workflow.
+- Running `gbrain embed --stale`, `gbrain dream`, `gbrain autopilot --install`, `gbrain onboard --auto`, or `tokenmax` without explicit cost approval.
+- Importing a nonexistent or wrong directory and treating a zero-page import as success.
+- Forgetting to update the vault index/catalog and log after creating or materially updating vault pages.
+- Recording API keys, tokens, or raw secrets in the vault or final response.
+
+## Tools Used
+
+- `read_file` — read vault schema/index/log and target notes.
+- `search_files` — find existing vault pages and avoid duplicates.
+- `write_file` / `patch` — create or update vault pages.
+- `terminal` — run `gbrain`, `git`, and environment checks with secret values redacted.
+
+## Safe Commands
+
+```bash
+export PATH="$HOME/.bun/bin:$PATH"
+gbrain config set search.mode conservative
+gbrain import "$OBSIDIAN_VAULT_PATH" --no-embed
+gbrain extract links --source fs --dir "$OBSIDIAN_VAULT_PATH"
+gbrain stats
+gbrain search modes
+```
+
+## Paid / Approval-Gated Commands
+
+```bash
+gbrain providers test --model <provider:model>
+gbrain embed --stale
+gbrain dream
+gbrain autopilot --install
+gbrain onboard --auto --max-usd 5
+gbrain config set search.mode tokenmax
+```
+
+## Verification Checklist
+
+- [ ] Vault path exists and is the intended source.
+- [ ] Vault operating files were read before edits when present.
+- [ ] Existing pages/skills were searched to avoid duplicates.
+- [ ] New/updated vault pages follow the vault schema and link convention.
+- [ ] Vault index/catalog updated for new pages when present.
+- [ ] Vault log appended for meaningful actions when present.
+- [ ] `gbrain import ... --no-embed` completed.
+- [ ] `gbrain stats` recorded pages/chunks/embeddings/links.
+- [ ] `gbrain search modes` confirms conservative mode unless a different mode was explicitly approved.
+- [ ] No paid/background commands ran without approval.

+# Skill Vault Capture Policy
+
+## Contract
+
+This skill guarantees:
+
+- Durable operational learnings, newly adopted skills, and important environment/setup changes are captured into the Obsidian vault rather than left only in chat memory.
+- An existing page is updated when the knowledge clearly belongs there; a new page is created only when the topic is distinct and likely to recur.
+- Every new vault page is added to `index.md`.
+- Every meaningful create/update appends a dated entry to `log.md`.
+- Small linked pages are preferred over one giant running note.
+
+## Phases
+
+1. **Classify the learning.**
+   - New gbrain operating rule, cost control, or embedding/provider change.
+   - New agent-fork / harness / coding-tool integration fact.
+   - New Obsidian vault workflow or structure decision.
+   - New recurring agent skill that changes how the agent should operate here.
+
+2. **Avoid duplicates.**
+   - Search the vault for an existing page that already owns the topic.
+   - If found, update it with a new section or dated note rather than creating a near-duplicate.
+
+3. **Create when distinct.**
+   - Place new pages under the vault schema: `_meta/` for operating notes, `concepts/` for workflows, `entities/` for tools/people.
+   - Use YAML frontmatter and at least two `[[wikilinks]]` unless it is a short seed page.
+
+4. **Update navigation.**
+   - Add the page to `index.md` under the correct type heading.
+   - Append a `## [YYYY-MM-DD] create|update | subject` entry to `log.md`.
+
+5. **Report the capture.**
+   - State which files changed and whether `index.md` / `log.md` were updated.
+
+## Output Format
+
+Use a short status block:
+
+| Item | Status |
+|---|---|
+| Learning classified | type |
+| Page created/updated | path |
+| index.md updated | yes/no |
+| log.md updated | yes/no |
+
+## Anti-Patterns
+
+- Leaving durable learnings only in chat memory.
+- Creating a near-duplicate page instead of updating the existing one.
+- Forgetting to update `index.md` and `log.md`.
+- Writing one giant running note instead of small linked pages.
+- Recording secrets, API keys, or raw credentials in the vault.
+
+## Tools Used
+
+- `read_file` — read `SCHEMA.md`, `index.md`, `log.md`, and target pages.
+- `search_files` — find existing pages to avoid duplicates.
+- `write_file` / `patch` — create or update vault pages and navigation.
+
+## Safe Commands
+
+```bash
+# inspect vault navigation before writing
+read SCHEMA.md index.md log.md
+# create or update a page, then refresh catalog/log
+# index.md: add [[page-slug]] under the matching type heading
+# log.md: append ## [YYYY-MM-DD] create|update | subject
+```
+
+## Verification Checklist
+
+- [ ] Vault schema/read files were checked before writing.
+- [ ] Existing pages were searched to avoid duplicates.
+- [ ] New/updated page has frontmatter and wikilinks.
+- [ ] `index.md` updated for new pages.
+- [ ] `log.md` appended for meaningful actions.
+- [ ] No secrets or raw credentials were written.
