+### 2026-01-26 [Session 20:00 - Parse Failure Format Fix]
+
+**Fixed critical usability bug in parse failure output:**
+
+1. **Root cause identified:**
+   - Phase 4 output: `event_id | kind | reason | (empty repo) | (empty npub)`
+   - Phase 5 expected: `repo | npub | kind | event_id | reason`
+   - Phase 5 was extracting columns 1-2 (event_id, kind) instead of columns 4-5 (repo, npub)
+   - Result: action-required.txt showed unusable event IDs instead of repo names
+
+2. **Fix implemented (commit `2e233b6`):**
+   - Enhanced Phase 4 (`30-extract-parse-failures.sh`) with `enrich_with_repo_npub()` function
+   - Builds lookup table from `announcements.json` mapping event_id → repo|npub
+   - Uses jq to extract d-tag (repo) and pubkey from announcements
+   - Optionally converts hex pubkeys to npub format using nak
+   - Enriches parse failures by looking up event_id and populating repo/npub columns
+   - Fixed Phase 5 column extraction from `{print $1 "|" $2}` to `{print $4 "|" $5}`
+
+3. **Verification:**
+   - Reran Phases 4-5 on existing analysis data
+   - 119 of 223 parse failures enriched with repo/npub (53%)
+   - Remaining 104 have empty repo/npub (event_ids not in announcements.json)
+   - Output now shows: `bit2factor | npub13kkpy... | parse failure logged | fix event format`
+   - Instead of: `000014b2... | 30617 | parse failure logged | fix event format`
+
+4. **Impact:**
+   - Parse failure results now immediately actionable
+   - Users can identify which repos have format issues
+   - No need to manually look up event IDs
+
 2. **Parse failure investigation:**
    - Initial count: 446 invalid announcements (WRONG - double-counting bug)
    - Root cause: Same event logged with hex ID and note1 (bech32) ID
