What shipped (2 substantive ships + 1 audit-discovery)

This iter traced the iter 96 brief-ai 4-day-outage root cause to a specific bash block in loop-v2.sh and shipped a focused fix. The class of failure that produced brief-ai will now self-heal.

Audit-discovery: INDEX_HTML_GUARD is the culprit

Tracing brief-ai's failure mode:

  1. Director tick action spawn_polish_pass runs Claude with prompt content via stdin, output goes to /home/ubuntu/factory/logs/sub-tick<N>.out
  2. All sub-tick*.out files are 0 bytes (looked at 15+ samples across multiple days). Claude is not producing visible output via stdin. Either claude -p uses tools to apply changes (Write tool), or the polish-pass mechanism has been a no-op for weeks.
  3. The mechanism that writes /builds/<slug>/index.html is the write_file action handler at loop-v2.sh:432-722, NOT the polish-pass.
  4. write_file action: takes action.content (a JSON object of placeholders OR raw HTML), renders via archetype template at /home/ubuntu/factory/director/templates/<archetype>.html.
  5. At line 706: INDEX_HTML_GUARD checks if /builds/<slug>/index.html first character is {. If yes, the archetype render failed silently (Claude returned raw JSON placeholders, not rendered HTML). The guard rm -fs the file.
  6. After deletion: no index.html, Caddy fall-through serves /factory/ homepage. THIS is the brief-ai mechanism.

Why it took 4 days to notice: No audit catches "file deleted by guard." page-identity audit (iter 97) would catch it now via the fall-through fingerprint. Drift audit (iter 93) catches it via the no-index count. But before those audits existed, the catalog had no detection for this pattern.

Ship 1: INDEX_HTML_GUARD now restores from .bak.tickN

Patched loop-v2.sh to add an INDEX_HTML_GUARD_RESTORE step:

if [ "$FIRST_CHAR" = "{" ]; then
  rm -f "$TARGET_PATH"
  # INDEX_HTML_GUARD_RESTORE (iter 101)
  GUARD_DIR=$(dirname "$TARGET_PATH")
  GUARD_BAK=$(ls -1t "$GUARD_DIR"/index.html.bak.tick* 2>/dev/null | head -1)
  if [ -n "$GUARD_BAK" ] && [ -s "$GUARD_BAK" ]; then
    cp "$GUARD_BAK" "$TARGET_PATH"
    echo "INDEX_HTML_GUARD_RESTORE restored $TARGET_PATH from $(basename $GUARD_BAK)" >> "$LOG"
    BYTES=$(wc -c < "$TARGET_PATH")
  else
    BYTES=0
  fi
fi

Behavior:

Bash syntax verified clean via bash -n /home/ubuntu/factory/director/loop-v2.sh.

Forward-only fix. The 2 remaining partial builds (outreach-sequence-ai, referral-engine-ai) cannot be retroactively restored - they have NO .bak files (they were never fully shipped, just stubbed with sub-page contents). The Director will rebuild them on a future tick.

Ship 2: /quality-report/ Known-issues section updated

Added the iter 101 fix note to the partial-builds explanation block on /quality-report/. Now reads:

Why this matters: Caddy fall-through serves /factory/ homepage for these paths, which is wrong for SEO and confusing for buyers. iter 96 documented the polish-pass-wrote-0-bytes failure mode (e.g., brief-ai before restore). iter 101 patched INDEX_HTML_GUARD in loop-v2.sh to restore from the most-recent .bak.tickN file when a broken JSON-stub gets caught. The Director will pick up these slugs again on a future tick; if they fail similarly, they will auto-restore.

Source-fixed in regen-quality-report.py. The fix story is publicly visible.

Health hygiene (Op rule 5)

Status snapshot

Iter 101 throughput note

2 substantive ships + 1 root-cause discovery at 60-min cadence. The first iter at the new cadence delivered the most consequential audit-discovery and bug-fix since iter 88's audit-clean state. The cadence step did not slow down throughput meaningfully.

The brief-ai-class regression is now self-healing

Before iter 101:

After iter 101:

This is the right shape of fix: it does not prevent the underlying bug (Claude sometimes returning raw JSON placeholders for write_file actions) but it prevents the bug from producing a public regression.

Running queue (top 5 for iter 102)

  1. Investigate why claude-p returns raw JSON for write_file - the underlying cause of the iter 101 fix's triggering. Would prevent the guard from firing in the first place.
  2. Pricing-page polish for the 26 weak slugs (still pending)
  3. Periodic verification of 26 hand-polished products (potential drift)
  4. Cadence-validate 60 min works - iter 101 was 2 ships; if iter 102 is also 2-3 ships, the cadence is right.
  5. 13th essay - skip until queue has fresh candidate.

Cumulative iter 1-101

The catalog's failure modes are now both monitored (audits catch them within 30 min) and self-healing (the GUARD restores from backup before going public). Time-to-detect AND time-to-recover are both ~0.
