Pending work for 2026-05-06 — substrate finishing tasks	Concrete to-dos carrying over from 2026-05-05's substrate restoration day. Order by dependency. All small (under an hour each). Most blocked behind a Claude Code restart that brings MCP back.	project	a156edbb-0c3d-4285-b3ed-f5a45b8dda66	claude-memory/pending-work-2026-05-06

Pending work for 2026-05-06

The 2026-05-05 substrate restoration left a clean working state but ~5 small tasks pulling forward. Most are blocked behind a Claude Code restart (which respawns MCP). Order matters — earlier tasks unblock later ones.

---

1. Wake-up checks (before anything substantive)

Before touching anything, check current state:

# Mining: did it complete overnight?
sqlite3 ~/.mempalace/palace/chroma.sqlite3 \
  'SELECT COUNT(*) FROM embeddings e JOIN segments s ON e.segment_id=s.id JOIN collections c ON s.collection=c.id WHERE c.name="mempalace_drawers";'
# Expect: ~600k+ if mine completed; ~480-560k if still in Loeb tail
tail -10 /tmp/mine_2026-05-05.log
ps -ef | grep "mempalace mine" | grep -v grep   # empty if done

# Marker: status of 15-PDF batch (4 Alexander Nature of Order books are the tail)
tail -5 /tmp/marker_2026-05-05.log
ls ~/_Dev/chamber-library/converted_texts/_pending_chamber_metadata/   # number of completed books
ps -ef | grep marker_single | grep -v grep   # empty if done

---

2. Restart Claude Code (unblocks MCP, hook end-to-end, diary_write)

The MCP server (mempalace-mcp) was killed during this morning's max_seq_id repair and never restarted. It auto-respawns when Claude Code starts. The hook patch is verified working but the save it forces routes through MCP — so until Claude Code restarts, no diary auto-saves can complete.

A clean Claude Code restart restores three things at once: MCP server up, fresh session for hook to count exchanges from, and the new fresh-palace substrate fully connected.

Recommended timing: after wake-up checks confirm mining/Marker state, restart Claude Code. Either:

• Quit and re-launch the app
• Or (in a fresh terminal): pkill -f mempalace-mcp then start a new Claude Code session

---

3. Verify hook patch on first post-restart turn

After the first assistant turn in the new session, the Stop hook should fire with a real session_id and exchange count:

tail -3 ~/.mempalace/hook_state/hook.log

Expected: [HH:MM:SS] Session <UUID>: <N> exchanges, <N> since last save — NOT Session unknown: 0 exchanges.

If still showing "Session unknown" → patch didn't survive a git pull (mempalace got updated overnight). Re-apply: see §7 below.

If new format → fix is verified end-to-end.

4. Supplementary mine of new shelves added 2026-05-05 (NOT picked up by yesterday's mine)

The 2026-05-05 mine had hardcoded TARGETS. Content added during the day that the mine won't have picked up:

Shelves NOT in the original TARGETS array (need full mine):

• traditions/contemporary_voices/letters_and_memory/ (6 files: Yates Art of Memory, Manguel ×3, Adler How to Read a Book, Foer Moonwalking)
• traditions/music_performance/ (Taruskin OHWM 5-vol, Heartz, Swafford ×2 — joining existing 3 files; need full re-mine of shelf since the existing 3 were never mined)
• traditions/history/ (Davies Europe)

Shelves where mining phase already completed before files were added (need re-mine):

• collections/style_guides/ — Strunk added after phase B done
• traditions/art_culture/visual_culture/ — 3 Solnit titles added after phase done

Files added late to existing TARGETS (may or may not have been picked up depending on mine timing):

• traditions/literature/classical/ — Rilke ×3, Stevens, Whitman, Eliot ×2, Thoreau (added before the literature/classical phase, should ride along)

Quick supplementary mine command (after Claude Code restart so MCP is up — though mempalace mine works via CLI regardless):

# All into wing chamber_library to match existing curation
for target in \
  collections/style_guides \
  traditions/contemporary_voices/letters_and_memory \
  traditions/music_performance \
  traditions/art_culture/visual_culture \
  traditions/history; do
  mempalace mine "$HOME/_Dev/chamber-library/converted_texts/$target" --wing chamber_library
done

(style_guides could use a different wing if the existing 8 are already mined under a different wing — check first.)

Expected runtime: ~5-10 min total. mempalace's dedup will skip files already mined.

5. OCR pipeline for two scan-only epubs

Two epubs from yesterday's ARC slate were image-only scans (no extractable text). They need OCR.

Files:

• Ross W Duffin/How Equal Temperament Ruined Harmony (and Whys You SHould Care) (737)/...epub (33 MB)
• Treatise On The Fundamentals Of Violin Playing/Leopold Mozart (664)/...epub (64 MB) — Leopold Mozart's treatise

Pipeline (Calibre's ebook-convert → PDF → Marker → mine):

# Setup: symlink if not done already
ln -s /Applications/calibre.app/Contents/MacOS/ebook-convert /opt/homebrew/bin/ebook-convert

LIB="/Users/davidglidden/Documents/The Library [ePub_AWZ3]/The Library [ePub_AWZ3]"
TMP=/tmp/scan-pdfs-2026-05-06
mkdir -p "$TMP"

ebook-convert "$LIB/Ross W Duffin/.../...epub" "$TMP/duffin-equal-temperament.pdf"
ebook-convert "$LIB/Treatise On The Fundamentals Of Violin Playing/.../...epub" "$TMP/leopold-mozart-violin-treatise.pdf"

# Then Marker (after current 15-PDF batch wraps):
~/.local/marker-venv/bin/marker_single "$TMP/duffin-equal-temperament.pdf" \
  --output_dir "$HOME/_Dev/chamber-library/converted_texts/traditions/music_performance"
~/.local/marker-venv/bin/marker_single "$TMP/leopold-mozart-violin-treatise.pdf" \
  --output_dir "$HOME/_Dev/chamber-library/converted_texts/traditions/music_performance"

# Then mine (or include in §4's supplementary mine if running after this):
mempalace mine "$HOME/_Dev/chamber-library/converted_texts/traditions/music_performance" --wing chamber_library

Estimated time: ~30 sec each for ebook-convert; ~1-2 hr each for Marker depending on page count + dpi. Schedule after main Marker batch finishes.

---

6. Mine the Marker-converted superpower PDFs

The 15-PDF Marker batch from 2026-05-05 places output at:

~/_Dev/chamber-library/converted_texts/_pending_chamber_metadata/<book>/

When Marker finishes (likely sometime tomorrow, 4 Alexander Nature of Order books are the slow tail), mine these into wing chamber_library:

mempalace mine ~/_Dev/chamber-library/converted_texts/_pending_chamber_metadata --wing chamber_library

Estimated: 30-60 min depending on output sizes.

The 15 books being added: Hochuli, Müller-Brockmann, Smeijers, Morison, Rutter, Bringhurst Solid Form, Alexander Timeless Way + Oregon Experiment + 4 Nature of Order books, Bachelard ×3 (English versions of Fire/Air/Reverie).

After mining, consider moving the converted markdowns out of _pending_chamber_metadata/ into proper chamber-library subdirs (e.g., Hochuli → collections/typography/, Bachelard English → traditions/critical_modernity/phenomenology/, Alexander → traditions/contemporary_voices/environmental/). This is post-mining cleanup; staging dir is meant to be temporary per yesterday's design.

---

7. Re-apply hook patch if mempalace was pulled overnight

Local patch in ~/_Dev/mempalace/hooks/mempal_save_hook.sh will be reverted by any git pull. To re-apply:

Around line 85, replace:

mapfile -t _mempal_parsed < <(echo "$INPUT" | "$MEMPAL_PYTHON_BIN" -c "
[python script]
" 2>/dev/null)

with:

_mempal_parsed=()
while IFS= read -r _line; do
    _mempal_parsed+=("$_line")
done < <(echo "$INPUT" | "$MEMPAL_PYTHON_BIN" -c "
[same python script]
" 2>/dev/null)

The detailed reasoning + the exact diff lives in the upstream issue draft at ~/_Dev/mempalace/.local-data/upstream-issue-bash32-mapfile-2026-05-05.md.

---

8. File upstream issues (drafts ready)

Two drafts in ~/_Dev/mempalace/.local-data/:

• upstream-issue-draft-2026-05-05.md — mempalace mine reports drawer counts at submission, not commit (lying-counter; silent-drop on max_seq_id poisoning)
• upstream-issue-bash32-mapfile-2026-05-05.md — Stop hook silently fails on macOS bash 3.2 (mapfile incompatibility)

Both reviewed and ready. File via gh issue create against the appropriate mempalace repo. Steward to authorize submission.

9. gemma4:e4b ollama model decision (carried from 2026-05-04)

9.6 GB unused model. Yesterday's open horizon. Triage: kept or remove? Quick ollama show gemma4:e4b + decision.

---

Order of attack (recommended)

1. Wake-up checks (§1) — 2 min
2. Restart Claude Code (§2) — 1 min
3. Verify hook (§3) — 30 sec
4. Re-apply hook patch if needed (§7) — 2 min if needed
5. Start ebook-convert (§5) for the two scan epubs while doing other work — 1 min to kick off
6. Supplementary mine (§4) — 5-10 min
7. When Marker batch wraps: mine converted PDFs (§6) — 30-60 min
8. When ebook-converts finish: queue Marker on the 2 scans (§5) — runs in background
9. File upstream issues (§8) — 10 min
10. gemma4:e4b decision (§9) — 5 min

Then: actually working on ARC again with the substrate fully restored, the panel deeper than ever, and the hook auto-save chain operative end-to-end.
