Memex - Consolidate

Wikilink rule: When referencing any file in markdown, always use [[filename]] wikilink format.

Independent drift sweep that session-end deliberately doesn't do. Four phases run in order: dedup, decisions contradictions, orphans, decisions compression. Read-only by default; --fix only applies safe annotations.

---

Step 0: Detect workspace and acquire lock

Run WORKSPACE_ROOT=$(pwd) && echo "$WORKSPACE_ROOT" via Bash. Confirm _MANIFEST.md exists; if not, tell the user to run /memex:init and stop.

Acquire memory/.consolidate.lock and check the 24-hour cooldown in memory/.consolidate-runs.log. Both follow the shared bulk-write convention. See references/locking.md.

---

Step 1: Dedup

Detect candidate duplicate files:

1. List all .md files in domain folders. Skip memory/, scratch/, .git, .obsidian, .claude, memex.
2. Group files where:
   • Filename stems are similar (Levenshtein distance ≤ 2 on lowercase stems), OR
   • Top wikilinks (the 5 most frequent [[targets]] cited inside) overlap by ≥ 80%.
3. For each group of ≥ 2 candidates, list: file path, file size, last-modified date, one-line summary of subject overlap.

Output but do not auto-merge. Dedup is user-confirmed always. --fix does not auto-merge files.

---

Step 2: Decisions contradiction sweep

Read decisions.md. Scan newer entries for explicit override language referencing earlier entries:

supersedes, replaces, dropped, no longer, instead of, reverses, overrides

For each match:

1. Find the older entry being referenced (string-match on the topic).
2. Check whether it's already annotated with ~~strikethrough~~ and (superseded YYYY-MM-DD).

If unannotated:

• Show the pair: old entry text, new entry text.
• Suggest: "Annotate the old entry with strikethrough and a (superseded <date>) marker."

With --fix: Apply the strikethrough + supersession marker automatically. Same logic as /memex:lint --fix's decision-consistency annotation.

This is keyword-explicit detection only. Don't infer contradictions from topical similarity. False positives are louder than false negatives in a write-back operation.

---

Step 3: Orphan check

Three sub-checks.

3a. Wikilink dangling

Run ${CLAUDE_SKILL_DIR}/scripts/verify-wikilinks.py against the workspace. Report broken wikilinks. With --fix, do nothing. Broken wikilinks need user judgment.

3b. Frontmatter dangling and graph refresh

Run ${CLAUDE_SKILL_DIR}/scripts/extract-graph.py against the workspace.

First run with --check to surface dangling edges (typed references to missing files). Report each.

Then run without --check to rewrite memory/.graph.md with the current graph state. Consolidate is the regular refresh point for the graph (along with /memex:reindex); session-end no longer does this.

Skip both if the script is unresolvable. Typed edges are opt-in.

3c. Hub orphans

For each domain in the Hub Map: list .md files on disk that aren't in the hub's table (excluding the hub index itself, _CLOSETS.md, and _CLOSETS-archive.md). These are files dropped in the folder without being wired up.

With --fix, propose adding them to the hub. Don't auto-add. Wikilink summaries need user/agent judgment.

---

Step 4: Decisions compression

Read decisions.md. If it has fewer than 60 lines, skip this phase entirely (no pressure on the 100-line cap).

Otherwise, scan the file for compression candidates by these concrete rules:

4a. Drop redundant supersession pairs

For each ~~strikethrough~~ entry annotated (superseded YYYY-MM-DD), check whether the superseding entry exists later in the file and stands on its own. If yes, the strikethrough entry is now redundant detail.

With --fix: Replace the original verbose strikethrough entry plus its superseder with a single one-line summary:

**YYYY-MM-DD** - <new fact>; replaces <old fact> (was <YYYY-MM-DD>)

Without --fix: list the candidate pairs and the proposed merged form.

4b. Collapse same-period clusters

Group consecutive entries by ISO week (Monday-Sunday). For each week with ≥3 entries about overlapping topics (≥50% subject overlap based on noun matches in the entry text), the cluster is a candidate.

With --fix: Combine into one entry with sub-bullets, preserving every unique fact:

**YYYY-MM-DD–YYYY-MM-DD** - [topic]
  - <fact 1 verbatim>
  - <fact 2 verbatim>
  - <fact 3 verbatim>

Without --fix: list candidate clusters and proposed combined form.

4c. Compression bounds

Compression preserves every unique fact. If two entries say the same thing differently, keep the clearer one verbatim. If they say different things, keep both as sub-bullets. Never paraphrase. Never drop a fact because it "feels redundant" — the test is "would re-reading this in 6 months recover the same retrieval signal?"

If decisions.md is at or above 95 lines and --fix is not set, surface a hard warning in the report: "decisions.md at lines; approaching 100-line cap. Run /memex:consolidate --fix to compress."

---

Step 5: Record the run

Append to memory/.consolidate-runs.log (format in references/locking.md):

YYYY-MM-DDTHH:MM:SS  dedup=<N> decisions-contradictions=<M> orphans=<K> decisions-compressed=<D>  status=<ok|partial>

Clear memory/.consolidate.lock.

Step 6: Output report

Memex Consolidation Report

DEDUP: [PASS / N candidate groups]
  [...]

DECISIONS CONTRADICTIONS: [PASS / N unannotated pairs]
  Old: <text> -- New: <text> -- fix: add ~~strikethrough~~ + (superseded YYYY-MM-DD)
  [...]

ORPHANS: [PASS / N files]
  Wikilinks: [N broken / CLEAN]
  Typed-edge graph: [N dangling / CLEAN]
  Hub orphans: [path - "fits domain X" if known]
  [...]

DECISIONS COMPRESSION: [PASS / N candidates / N applied]
  decisions.md: [N] lines
  Supersession pairs: [count]
  Same-period clusters: [count]
  [...]

Last run: [from .consolidate-runs.log]

End with: Run /memex:lint for the per-check live report at any time.

Gotchas

• The lock is best-effort. A killed process leaves it stale. Stale locks (over 30 min old) are treated as freed. See references/locking.md.
• --fix only annotates explicit decision supersessions (newer entry literally references the older with "supersedes/replaces/dropped/no longer/instead of/reverses/overrides"). Anything ambiguous waits for the user.
• Dedup never auto-merges. --fix is for safe annotations only.
• Decisions compression preserves every unique fact. Never paraphrase; never drop a fact because it feels redundant. The test is whether re-reading the compressed log in 6 months still recovers the original retrieval signal. Verbatim user-stated facts ("allergic to coffee", "raised $42K") stay verbatim.
• Decisions compression is the only place this happens. Session-end no longer compresses decisions — it only appends. This skill is the compression owner; run it when decisions.md approaches the 100-line cap.
• Consolidate is the dedup/contradiction/orphan/decisions-compression owner; session-end stays lean by deferring this work here. Run consolidate on its own cadence, not as a session-end appendage.
• For closets coverage gaps, run /memex:reindex. For summary format upgrades, run /memex:resummarize. Consolidate doesn't rebuild closets or summaries.
