Three layers of contributor-attribution bug surfaced by Apr 24 leaderboard
investigation. alexastrum, thesensatore, cameron-s1 all had real merged
contributions but zero credit in the contributors table.
1. lib/attribution.py: parse_attribution() only read `attribution_sourcer:`
prefix-keyed flat fields. ~42% of claim files (535/1280) use the bare-key
form `sourcer: alexastrum` written by extract.py. Added bare-key handling
between the prefixed-flat path and the legacy-source-field fallback.
Block format (`attribution: { sourcer: [...] }`) still wins when present.
2. lib/contributor.py: record_contributor_attribution() parsed the diff text
with regex looking for `+- handle: "X"` lines. This matched neither the
bare-key flat format nor the `attribution: { sourcer: [...] }` block
format Leo uses for manual extractions. Replaced the regex parser with
a file walker that calls attribution.parse_attribution_from_file() on
each changed knowledge file — single source of truth for both formats.
3. scripts/backfill-sourcer-attribution.py: walks all merged knowledge files,
re-attributes via the canonical parser, upserts contributors. Default
additive mode preserves existing high counts (e.g. m3taversal.sourcer=1011
reflects Telegram-curator credit accumulated via a different code path
that this fix does not touch). --reset flag for the destructive case.
Dry-run preview (additive mode):
- 670 NEW contributors to insert (mostly source-citation handles)
- 77 EXISTING contributors with under-counted role columns
- alexastrum: 0 → 6, thesensatore: 0 → 5, cameron-s1: 0 → 2
- astra.sourcer: 0 → 96, leo.sourcer: 0 → 44, theseus.sourcer: 0 → 18
- m3taversal.sourcer: 1011 (preserved, not 22 from file walk)

backfill-sources.py runs every 15 minutes and derives sources.status
purely from directory location. If a source file is in inbox/queue/,
it blindly overwrites the DB status to 'unprocessed' — even when the
DB already had 'extracted' or 'null_result'.
This is why the 43 zombies kept coming back after manual backfill:
cron re-reset them every 15 minutes, then each 4h cooldown expiry
re-triggered runaway extraction on the same source.
Fix: never regress from a terminal status (extracted, null_result,
error, ghost_no_file) to 'unprocessed'. File location is ambiguous
(legitimately new vs. zombie from failed archive); DB is authoritative.
Legitimate re-extraction still works — it goes through the needs_reextraction
path which is unaffected by this gate.

Crawls domains/foundations/core/decisions for [[wiki-links]], resolves
against claim files, entities, maps, and agents. Reports dead links,
orphans, and connectivity stats. Prerequisite for CI scoring connectivity
bonus — broken links would inflate scores.

Adds async git-log-based endpoint for cumulative contributor and claim
tracking. 5-minute cache, excludes bot accounts, tags founding contributors.
Standalone CLI script also included for ad-hoc data generation.

Orphan ratio at 39.6% (443/1118 claims) vs <15% target. Root cause:
reweave threshold 0.70 too strict for text-embedding-3-small — 56% of
orphans found "no neighbors." At 0.55, dry-run shows 0% no-neighbor
skips. Batch size 200 clears backlog in ~3-4 nights at ~$0.20/run.
