name: preserve
description: >
  Single write point for the vault. Centralizes entity detection, textual matching,
  entity creation/update, and bidirectional linking. Accepts structured input
  (list of entities), free-form input (text, meeting notes, session context),
  or graphify output (graph.json + obsidian markdown from /graphify pipeline).
  Use when: "bedrock preserve", "bedrock-preserve", "save to vault", "record in vault", "/bedrock:preserve",
  or when another skill (e.g., /bedrock:learn) needs to persist entities in the vault.

# /bedrock:preserve — Single Write Point for the Vault

## Plugin Paths

Entity definitions and templates are in the plugin directory, not in the vault root.
Use the "Base directory for this skill" provided at invocation to resolve paths:

- Entity definitions: `<base_dir>/../../entities/`
- Templates: `<base_dir>/../../templates/{type}/_template.md`
- Plugin CLAUDE.md: `<base_dir>/../../CLAUDE.md` (already injected automatically into context)

Where `<base_dir>` is the path provided in "Base directory for this skill".

---

## Vault Resolution

Resolve which vault to operate on. This skill can be invoked from any directory.

**Step 1 — Parse `--vault` flag:**
Check if the input arguments include `--vault <name>`. If found, extract the vault name and remove it from the arguments before further parsing.

**Step 2 — Resolve vault path:**

1. **If `--vault <name>` was provided:**
   Read the vault registry at `<base_dir>/../../vaults.json`. Find the entry matching the name.
   If not found: error — "Vault `<name>` is not registered. Run `/bedrock:vaults` to see available vaults."
   If found: set `VAULT_PATH` to the entry's `path` value.

2. **If no `--vault` flag — CWD detection:**
   Read `<base_dir>/../../vaults.json`. Check if the current working directory is inside any registered vault path
   (CWD starts with a registered vault's absolute path). If multiple match, use the longest path (most specific).
   If found: set `VAULT_PATH` to the matching vault's `path`.

3. **If CWD detection fails — default vault:**
   From the registry, find the vault with `"default": true`.
   If found: set `VAULT_PATH` to the default vault's `path`.

4. **If no resolution:**
   Error — "No vault resolved. Available vaults:" followed by the registry listing.
   "Use `--vault <name>` to specify, or run `/bedrock:setup` to register a vault."

**Step 3 — Validate vault path:**
```bash
test -d "<VAULT_PATH>" && echo "exists" || echo "missing"
```
If missing: error — "Vault path `<VAULT_PATH>` does not exist on disk. Run `/bedrock:setup` to re-register."

**Step 4 — Read vault config:**
```bash
cat <VAULT_PATH>/.bedrock/config.json 2>/dev/null
```
Extract `language`, `git.strategy`, and other relevant fields for use in later phases.

**From this point forward, ALL vault file operations use `<VAULT_PATH>` as the root.**
- Entity directories: `<VAULT_PATH>/actors/`, `<VAULT_PATH>/people/`, etc.
- Vault config: `<VAULT_PATH>/.bedrock/config.json`
- Git operations: `git -C <VAULT_PATH> <command>`

## Overview

This skill centralizes ALL write logic for the vault. It receives input (structured, free-form,
or graphify output), identifies entities, correlates with the existing vault, proposes changes
to the user, and executes after confirmation. It is the only path to create or update entities in the vault (except `/sync-people`
which handles people/teams via GitHub API).

**You are an execution agent.** Follow the phases below in order, without skipping steps.

---

## Phase 0 — Pre-Write Setup

Two pre-flight steps run before any input parsing: synchronize the vault with its remote, then (when applicable) merge an incoming graphify output directory into the vault's cumulative `graphify-out/`.

### 0.1 Vault Sync

Execute:
```bash
git -C <VAULT_PATH> pull --rebase origin main
```

If the pull fails:
- No remote configured: warn "No remote configured. Working locally." and proceed.
- Pull conflict: `git -C <VAULT_PATH> rebase --abort` and warn the user. DO NOT proceed without resolving.
- Otherwise: proceed.

### 0.2 Merge Incoming Graphify Output

**When this runs:** Only when the skill was invoked with a `graphify_output_path` argument pointing at a graphify output directory (e.g., `/bedrock:learn` passes `$TEACH_TMP/graphify-out-new/`). Free-form text input and structured entity-list input skip this sub-phase entirely.

**Skip condition (backward compat):** If the input's `graphify_output_path` resolves to the same absolute path as `<VAULT_PATH>/graphify-out/`, skip this sub-phase. Legacy callers (and `/bedrock:sync` in its current form) point at the vault's own output directory — there is nothing to merge. Use `realpath` (or equivalent) to compare:

```bash
incoming_real=$(cd "<graphify_output_path>" 2>/dev/null && pwd -P)
vault_real=$(cd "<VAULT_PATH>/graphify-out" 2>/dev/null && pwd -P)
if [ "$incoming_real" = "$vault_real" ]; then
  echo "Phase 0.2: graphify_output_path already points at the vault — skipping merge."
  # proceed to Phase 1 with graphify_output_path unchanged
fi
```

**Skip condition (no graphify input):** If the input is free-form text, structured entity list, or otherwise does not include `graphify_output_path`, skip.

---

**Step 1 — Validate incoming directory.** Verify that `<graphify_output_path>/graph.json` exists, is non-empty, and parses as valid JSON. If invalid, abort with a clear error and do NOT mutate the vault:

```bash
if [ ! -s "<graphify_output_path>/graph.json" ]; then
  echo "ERROR: graph.json missing or empty in <graphify_output_path>. Aborting before vault mutation."
  exit 1
fi
python3 -c "import json,sys; json.load(open('<graphify_output_path>/graph.json'))" || { echo "ERROR: graph.json is not valid JSON."; exit 1; }
```

**Step 2 — First-ingestion edge case.** If `<VAULT_PATH>/graphify-out/` does not exist, promote the incoming directory wholesale (no re-merge pass) and record stats, then skip to Step 7:

```bash
if [ ! -d "<VAULT_PATH>/graphify-out" ]; then
  mkdir -p "<VAULT_PATH>"
  cp -R "<graphify_output_path>" "<VAULT_PATH>/graphify-out"
  echo "Phase 0.2: first ingestion — promoted incoming graphify output to <VAULT_PATH>/graphify-out/."
  # record: nodes_added = <count of nodes in graph.json>, nodes_merged = 0, edges_added = <count of edges>, stale_flag_set = false
  # skip to Step 7 (record stats) then exit sub-phase
fi
```

**Step 3 — Merge `graph.json` (nodes + edges).** Both files follow NetworkX node-link format (`{"nodes": [...], "edges": [...]}` or `"links"` — accept either key). Run the merge via an inline Python block to avoid hand-merging JSON in the prompt. Write the merged graph to a staging file, then atomically swap:

```bash
python3 - <<'PY'
import json, os, pathlib, shutil, sys

existing_path = pathlib.Path("<VAULT_PATH>/graphify-out/graph.json")
incoming_path = pathlib.Path("<graphify_output_path>/graph.json")
staging_path = existing_path.with_suffix(".json.staging")

with existing_path.open() as f:
    existing = json.load(f)
with incoming_path.open() as f:
    incoming = json.load(f)

# Accept both "edges" and "links" keys — normalize to "edges".
def _edges(g):
    return g.get("edges", g.get("links", []))

# --- Node merge keyed by id ---
def _union(a, b):
    # Preserve order; dedup by string representation.
    seen, out = set(), []
    for item in (a or []) + (b or []):
        key = json.dumps(item, sort_keys=True) if not isinstance(item, str) else item
        if key not in seen:
            seen.add(key)
            out.append(item)
    return out

def _dedup_sources_by_url(a, b):
    seen, out = set(), []
    for item in (a or []) + (b or []):
        if isinstance(item, dict) and "url" in item:
            if item["url"] in seen:
                continue
            seen.add(item["url"])
        out.append(item)
    return out

existing_nodes = {n["id"]: n for n in existing.get("nodes", [])}
nodes_added = 0
nodes_merged = 0
for inc in incoming.get("nodes", []):
    nid = inc["id"]
    if nid not in existing_nodes:
        existing_nodes[nid] = inc
        nodes_added += 1
    else:
        cur = existing_nodes[nid]
        # Union sources by URL
        if "sources" in inc or "sources" in cur:
            cur["sources"] = _dedup_sources_by_url(cur.get("sources"), inc.get("sources"))
        # Most-recent updated_at (YYYY-MM-DD lexical compare works)
        cur_ua, inc_ua = cur.get("updated_at"), inc.get("updated_at")
        if inc_ua and (not cur_ua or inc_ua > cur_ua):
            cur["updated_at"] = inc_ua
        # Union labels and tags
        for key in ("labels", "tags"):
            if key in inc or key in cur:
                cur[key] = _union(cur.get(key), inc.get(key))
        nodes_merged += 1

# --- Edge dedup keyed by (source, target, type/relation) ---
def _edge_key(e):
    return (e.get("source"), e.get("target"), e.get("type") or e.get("relation"))

existing_edges = _edges(existing)
seen_edges = {_edge_key(e) for e in existing_edges}
edges_added = 0
for inc_edge in _edges(incoming):
    k = _edge_key(inc_edge)
    if k in seen_edges:
        continue
    existing_edges.append(inc_edge)
    seen_edges.add(k)
    edges_added += 1

merged = dict(existing)
merged["nodes"] = list(existing_nodes.values())
# Preserve the key naming the existing file used.
merged_key = "edges" if "edges" in existing else ("links" if "links" in existing else "edges")
merged[merged_key] = existing_edges

with staging_path.open("w") as f:
    json.dump(merged, f, indent=2, ensure_ascii=False)

# Emit stats to stdout for capture.
print(json.dumps({"nodes_added": nodes_added, "nodes_merged": nodes_merged, "edges_added": edges_added}))
PY
```

Atomic swap after the Python block succeeds:
```bash
mv "<VAULT_PATH>/graphify-out/graph.json.staging" "<VAULT_PATH>/graphify-out/graph.json"
```

If the Python block exits non-zero, abort without running the `mv` — the vault's `graph.json` stays untouched.

**Step 4 — Append `obsidian/*.md` files.** For each markdown file in `<graphify_output_path>/obsidian/`:

- Skip any file whose `source_file` frontmatter value starts with `/tmp/` — these are ephemeral visualization files produced by `/bedrock:teach` and must not accumulate in the vault.
- If the corresponding file exists in `<VAULT_PATH>/graphify-out/obsidian/`: append the incoming content to the existing file, separated by `\n\n---\n\n`. Existing content is preserved verbatim.
- If it does not exist: copy the file into `<VAULT_PATH>/graphify-out/obsidian/`.

```bash
mkdir -p "<VAULT_PATH>/graphify-out/obsidian"
for src in "<graphify_output_path>/obsidian/"*.md; do
  [ -e "$src" ] || continue
  SRC_FILE=$(awk -F'"' '/^source_file:/{print $2; exit}' "$src")
  case "$SRC_FILE" in /tmp/*) continue ;; esac
  dest="<VAULT_PATH>/graphify-out/obsidian/$(basename "$src")"
  if [ -e "$dest" ]; then
    printf '\n\n---\n\n' >> "$dest"
    cat "$src" >> "$dest"
  else
    cp "$src" "$dest"
  fi
done
```

**Step 5 — Append `GRAPH_REPORT.md`.** If `<graphify_output_path>/GRAPH_REPORT.md` exists:

- If `<VAULT_PATH>/graphify-out/GRAPH_REPORT.md` exists: append a new dated section.
- If it does not exist: copy.

```bash
if [ -f "<graphify_output_path>/GRAPH_REPORT.md" ]; then
  dest="<VAULT_PATH>/graphify-out/GRAPH_REPORT.md"
  if [ -e "$dest" ]; then
    {
      printf '\n\n---\n\n# Merge on %s\n\n' "$(date +%Y-%m-%d)"
      cat "<graphify_output_path>/GRAPH_REPORT.md"
    } >> "$dest"
  else
    cp "<graphify_output_path>/GRAPH_REPORT.md" "$dest"
  fi
fi
```

**Step 6 — Mark `.graphify_analysis.json` stale.** If `<VAULT_PATH>/graphify-out/.graphify_analysis.json` exists, set a top-level `"stale": true` field. Other content is untouched:

```bash
analysis="<VAULT_PATH>/graphify-out/.graphify_analysis.json"
stale_flag_set=false
if [ -f "$analysis" ]; then
  python3 - <<PY
import json, pathlib
p = pathlib.Path("$analysis")
with p.open() as f:
    data = json.load(f)
data["stale"] = True
with p.open("w") as f:
    json.dump(data, f, indent=2, ensure_ascii=False)
PY
  stale_flag_set=true
fi
```

If the file does not exist, skip (nothing to mark).

**Step 7 — Record merge stats for the Phase 7 report.** Capture `nodes_added`, `nodes_merged`, `edges_added` (from Step 3's Python stdout) and `stale_flag_set` (from Step 6). These values are threaded through to Phase 7's report block under a new **"Graphify merge"** section and returned in the skill's result payload to the caller (e.g., `/bedrock:learn`).

**Step 8 — Point subsequent phases at the merged location.** After the merge succeeds, set `graphify_output_path := <VAULT_PATH>/graphify-out/` for all downstream phases. Phase 1.3 (graphify-output parsing), Phase 2 (matching), and the rest of the flow read from the merged vault location — not from the original temp input.

---

## Phase 1 — Parse Input

`/bedrock:preserve` accepts three input modes. Determine which to apply:

### 1.1 Structured input

When called by another skill (e.g., `/bedrock:learn`) or when the user provides an explicit list.
The format is an optional top-level header followed by a list of entities:

```yaml
# Optional top-level header — applies to all entities in the batch
actor_context: <actor-name>  # optional, kebab-case slug of an actor in the vault.
                             # When present, /preserve treats the batch as scoped to that actor:
                             # graphify nodes of file_type=document/paper become `code` of this actor
                             # with node_type ∈ {concept, decision} (see Phase 1.3 step 4).

entities:
  - type: actor | person | team | concept | topic | discussion | project | fleeting | code
    name: "canonical entity name"
    action: create | update
    content: "content to include in the entity body"
    relations:
      actors: ["actor-slug-1", "actor-slug-2"]
      people: ["person-slug-1"]
      teams: ["team-slug-1"]
      concepts: ["concept-slug-1"]
      topics: ["topic-slug-1"]
      discussions: ["discussion-slug-1"]
      projects: ["project-slug-1"]
      code: ["node-slug-1"]
    source: "github | confluence | jira | session | manual | gdoc | csv | graphify"
    metadata: {}  # additional frontmatter fields specific to the type
```

If the input is a bare list (no `entities:` key, no `actor_context`), accept it as a list of entities with `actor_context = null`. This preserves backward compatibility with callers that pre-date the field.

If the input follows this format (or something close): parse directly and go to Phase 2.

### 1.2 Free-form input

When the user provides natural text, meeting notes, session context, or any
unstructured content. Analyze the text and extract:

1. **Mentioned entities** — identify by name, alias, or reference:
   - People: names in "First Last" format
   - Actors: service names, APIs, repositories
   - Teams: squad names
   - Concepts: patterns, principles, techniques, protocols, abstractions
   - Topics: discussion themes, bugs, RFCs, features
   - Discussions: meetings, decisions, debates
   - Projects: initiatives, migrations, cross-team features

2. **Inferred action** — for each entity:
   - If the entity already exists in the vault: `update`
   - If the entity does not exist: `create`

3. **Content** — what was said about each entity in the input

4. **Relations** — infer which entities relate to each other based on context

5. **Source** — infer: `session` (conversation), `meeting-notes` (minutes), `manual` (typed text)

To classify new content, consult the plugin's entity definitions (see "Plugin Paths" section) (loaded in Phase 2.0):
- "When to create" section → positive criteria for creating a new entity
- "When NOT to create" section → exclusion criteria
- "How to distinguish from other types" section → disambiguation

Convert the result to the structured format from section 1.1 and proceed.

### 1.3 Graphify output input

When called by `/bedrock:learn` (or any skill) with a graphify output reference,
OR when the user invokes `/bedrock:preserve` directly pointing at a `graphify-out/` directory:

**Input format:**
- `graphify_output_path`: path to `graphify-out/` directory
- `source_url`: original external source URL/path (optional — may not be present for manual invocation)
- `source_type`: type of external source (optional)
- `actor_context`: kebab-case slug of an actor in the vault (optional). When present, the entire corpus is treated as belonging to that actor: `file_type=document/paper` nodes are classified as `code` of that actor with `node_type ∈ {concept, decision}` instead of as global `concept`/`topic`/`fleeting`. When absent, classification falls back to the corpus-agnostic logic (concept global / topic / fleeting).

**Detection:** If the input contains a path ending in `graphify-out/` or `graphify-out`,
or references `graph.json`, treat as graphify output input.

**Processing:**

1. **Read graph.json** from `graphify_output_path/graph.json`:
   - Parse NetworkX node-link format
   - Extract all nodes with: `id`, `label`, `file_type`, `source_file`, `source_location`
   - Extract all edges with: `source`, `target`, `relation`, `confidence`, `confidence_score`
   - If `graph.json` is missing or empty: abort with error "No graph.json found in graphify output. Run /graphify first."

2. **Read obsidian files** from `graphify_output_path/obsidian/*.md`:
   - For each markdown file, read frontmatter and body content
   - Correlate with graph.json by matching filename stem to node `id` (kebab-cased)
   - If obsidian file doesn't exist for a node: fall back to graph.json metadata alone

3. **Read analysis** from `graphify_output_path/.graphify_analysis.json` (if exists):
   - Extract community assignments (`community_id` per node), god nodes (`is_god_node`), community labels
   - Use community labels to inform `domain/*` tags when creating entities
   - If absent or `stale: true`, downstream steps fall back to graph-only signals (no community-aware grouping)

4. **Read configuration** from `<VAULT_PATH>/.bedrock/config.json` (best-effort):
   - `code.max_per_actor`: integer, default `200`. Per-actor cap on the number of `code` candidates produced from this corpus. No absolute global cap.
   - `code.cluster_threshold`: float, default `0.85`. Minimum `semantically_similar_to.confidence_score` for two nodes to be grouped into the same `code` candidate.
   - If `.bedrock/config.json` is missing or has no `code` block, use the defaults silently.

5. **Group nodes by semantic similarity** (BEFORE filtering and classification) — produces clusters that will each become at most one `code` candidate:
   - Build clusters by union-find:
     - Two nodes are in the same cluster if there is a `semantically_similar_to` edge between them with `confidence_score ≥ code.cluster_threshold`.
     - OR they share the same `community_id` (from `.graphify_analysis.json`) AND at least one of them is `is_god_node` OR both have `edge_count ≥ 2`. This guards against weakly-tied community co-membership.
   - If `.graphify_analysis.json` is absent or stale, only the `semantically_similar_to` rule applies.
   - Singletons (nodes with no qualifying neighbor) form their own cluster of size 1.
   - Each cluster carries: `cluster_id` (synthetic), `member_node_ids[]` (the union of node `id`s — this becomes the `graphify_node_ids` array of the resulting `code` entity), `representative` (the node with highest degree in the cluster — used for `label`, `source_file`, etc.).
   - Hard cap: maximum 50 nodes per cluster (defensive — runaway clusters indicate bad threshold).

6. **Classify clusters into vault entity types** — /preserve owns this classification.
   Read ALL entity definitions from the plugin (see "Plugin Paths") and apply:

   **When `actor_context` is present** (single-actor corpus):
   - `file_type: code` clusters → `code` for the actor, `node_type` ∈ {`function`, `class`, `module`, `interface`, `endpoint`} inferred from the representative node's label/edges.
   - `file_type: document` or `file_type: paper` clusters → `code` for the actor:
     - `node_type: decision` if the representative node has `rationale_for` edges OR the label/text contains decision markers (e.g., "ADR", "RFC", "decision", "chose", "decided").
     - `node_type: concept` otherwise.
   - The cluster's `actor` field is set to `[[<actor_context>]]` for all entities.

   **When `actor_context` is absent** (corpus-agnostic):
   - `file_type: code` clusters → `code` (parent actor inferred from `source_file` path or repo name in the path; if no actor can be inferred, classify as `fleeting`).
   - `file_type: document` or `file_type: paper` clusters → check for concept first: if the representative node describes a pattern, principle, technique, protocol, or abstraction AND is self-contained AND is not specific to a single actor → `concept` (global).
     - Non-concept document → classify using entity definitions ("When to create" / "When NOT to create" / "How to distinguish").
     - Non-concept paper → `topic` or `fleeting` depending on completeness criteria.
   - God nodes (`is_god_node`) → consider as `actor`, `concept`, or `topic`.
   - Apply Zettelkasten classification (section 1.4): if content doesn't meet completeness criteria → `fleeting`.

7. **Filter relevant clusters** (applied to `code` candidates only — non-code classifications keep their existing inclusion logic):
   - **Inclusion predicate:** representative node's strongest edge has `confidence ∈ {EXTRACTED, INFERRED}` AND at least one of:
     - `is_god_node` (from `.graphify_analysis.json`),
     - `degree > community_average_degree` (from `.graphify_analysis.json`; if analysis absent, use overall graph average),
     - `edge_count ≥ 2`.
   - **Exclusion:** representative label matches trivial patterns (case-insensitive substring of `Test`, `Tests`, `Mock`, `Fake`, `Builder`, `Stub`, `Fixture`) or the cluster only contains nodes flagged trivial by graphify.
   - **Per-actor cap:** group surviving `code` candidates by their resolved `actor`. Within each actor, rank by `is_god_node` (true first) > `degree` > `edge_count`. Keep the top `code.max_per_actor` (default `200`); discard the rest with a warning in the report listing how many were dropped per actor.
   - **No English keyword regex.** The previous label allowlist (`Service|Controller|...`) is removed.
   - For non-`code` classifications (concept global, topic, fleeting): include all that pass classification.

8. **Match against existing vault** — Use the textual matching logic from Phase 2 (filename, name, aliases, graphify ids). For `code` entities, the graphify-id match accepts both legacy singular `graphify_node_id` and the new `graphify_node_ids` array — match if the cluster's `member_node_ids` set intersects the entity's existing id set. Mark matched clusters as `update`, unmatched as `create`.

9. **Build internal structured format** for each classified + filtered cluster:
   - `type`: from classification (step 6).
   - `name`: kebab-cased label of the cluster's `representative` node.
   - `action`: `create` or `update` (from step 8 matching).
   - `content`: body of the obsidian markdown file matching the representative's id (or generate from graph.json metadata if no obsidian file). When the cluster has multiple members, include a brief "Grouped from N graphify nodes" note in the body listing the member ids — this preserves traceability.
   - `relations`: from graph.json edges of all member nodes (convert node ids to entity slugs via kebab-case; deduplicate).
   - `source`: from input `source_type` (or `"graphify"` if not provided).
   - `source_url`: from input `source_url` (if provided).
   - `source_type`: from input `source_type` (if provided).
   - `metadata`: for `code` entities, include:
     - `graphify_node_ids`: array — the cluster's `member_node_ids` (always written as array even when size is 1).
     - `actor`: wikilink of the parent actor (`[[<actor_context>]]` when set; otherwise inferred).
     - `node_type`: from step 6.
     - `source_file`: relative path from the representative node.
     - `confidence`: strongest edge confidence across all member nodes (`EXTRACTED` > `INFERRED` > `AMBIGUOUS`).
   - `metadata`: for `concept` (global) entities from graphify, include:
     - `graphify_node_ids`: array.
     - `confidence`: strongest edge confidence across all members.

10. **Proceed to Phase 3** (Change Proposal) — present the classified cluster list for user confirmation, then execute writes as normal (Phases 4-7).

> **Note:** When invoked directly by the user (not via /learn), the user confirmation in Phase 3
> is the only gate before writes. When invoked via /learn, /learn has already shown the user
> the graphify report (god nodes, communities) providing context for the confirmation.

### 1.4 Zettelkasten Classification

Before converting to structured format, classify each entity by Zettelkasten role.
Consult the plugin's entity definitions ("Completeness Criteria" section) to determine the correct type:

**Classification rule:**
- If the content meets the completeness criteria of a permanent type (actor, person, team) → classify as permanent
- If the content has a non-empty `graphify_node_ids` array (or legacy singular `graphify_node_id`) and `actor` defined → classify as `code` (permanent extension, sub-entity of actor)
- If the content defines a pattern, principle, technique, protocol, or abstraction that is self-contained and actor-independent → classify as `concept` (permanent)
- If the content meets the completeness criteria of a bridge type (topic, discussion) → classify as bridge
- If the content meets the completeness criteria of an index type (project) → classify as index
- **If the content does NOT meet the completeness criteria of any type** → classify as `fleeting`

**Heuristics for fleeting:**
- Vague mention without concrete data (no repo name, no full person name, no date, no decision)
- Idea or hypothesis without confirmation ("it seems like...", "maybe...", "someone mentioned...")
- Fragment of information without sufficient context to be self-contained
- Generic TODO without assignee or deadline

**When in doubt, err on the side of fleeting** — it is safer to capture as fleeting and promote later than to create an incomplete permanent entity.

If the input came from another skill (e.g., `/bedrock:learn`) and already includes a classification suggestion (`type: fleeting`), respect the suggestion but validate against the criteria above.

If no input was provided: ask the user "What would you like to preserve in the vault? Provide text, meeting notes, or a list of entities."

## Phase 2 — Matching with Existing Entities

**Objective:** Correlate entities from the input with the existing vault.

### 2.0 Read entity definitions

Read ALL entity definition files from the plugin (see "Plugin Paths" section):
`<base_dir>/../../entities/*.md`
These files define what each entity type is, when to create, when NOT to create, and how
to distinguish between types. Internalize these definitions — you will use them to classify new
content (especially in free-form mode, Phase 1.2).

### 2.1 Collect vault entities

List all files in each entity directory (exclude `_template.md` and `_template_node.md`):

```
<VAULT_PATH>/actors/*.md and <VAULT_PATH>/actors/*/*.md (actors can be folders)
<VAULT_PATH>/actors/*/nodes/*.md (code entities within actors)
<VAULT_PATH>/people/*.md
<VAULT_PATH>/teams/*.md
<VAULT_PATH>/topics/*.md
<VAULT_PATH>/discussions/*.md (if exists)
<VAULT_PATH>/projects/*.md (if exists)
<VAULT_PATH>/fleeting/*.md (if exists)
```

For each file found, extract:
- `filename` (without extension) — canonical identifier
- `name` (or `title`) from frontmatter — human-readable name
- `aliases` from frontmatter — alternative names
- `graphify_node_ids` from frontmatter — for code entities (if present, accept both the new array form and the legacy singular `graphify_node_id` string; normalize to a set of ids per entity)

### 2.2 Textual matching

For each entity from the input, check if it already exists in the vault:

**Match rules (in priority order):**

1. **Exact match by filename** (case-insensitive): `billing-api` == `billing-api`
2. **Match by name/title field** (case-insensitive): `"Billing API"` finds `billing-api.md`
3. **Match by aliases** (case-insensitive): `"BillingAPI"` finds `billing-api.md` if alias contains "BillingAPI"
4. **Match by filename without hyphens** (case-insensitive): `billing-api` → `billingapi` finds "BillingAPI"
5. **Match by graphify ids** (for code entities): set intersection between the input cluster's `graphify_node_ids` (array) and the vault entity's id set, where the vault entity's id set is normalized from EITHER `graphify_node_ids` (array, current schema) OR the legacy singular `graphify_node_id` (string treated as a 1-element set). Any non-empty intersection is a match. This is the most reliable match for code entities and takes priority over the others when present.

**Safety rules:**
- DO NOT match by substrings of 3 characters or fewer (e.g., "api" should not match everything)
- Maximum 20 correlations per entity type
- In case of ambiguity: record all candidates and resolve in Phase 3 (proposal)

### 2.3 Classify actions

For each entity from the input:
- If match found in vault: mark as `update` (update existing entity)
- If no match: mark as `create` (new entity)
- If the input already specified the action: respect the input's action

### 2.4 Enrich via external sources (best-effort)

For entities of type `actor` that have a `repository` field in frontmatter:

**GitHub MCP** (call directly, NOT via subagent):
- `mcp__plugin_github_github__list_pull_requests` → recent PRs (5, state=all, sort=updated)
- `mcp__plugin_github_github__list_c...
