Archive smoke round-3 Logbook row (tail 26→27) - #650
Merged
Conversation
Appends the first stacked-era attempt row to the Logbook archive: populace-us-2024-stacked-f001-s578-asec1688-acs15316-20260807T195238Z (disposition failed, 8 phases, wall 1142s, code_pin e97c54a), chained on the prior tail f3cffe94… with new tail 5d9c36bf…. Exported and validated through tools/logbook.py; the committed spool mirror gains the matching row file. Two same-era local attempts are receipted exclusions, not archive rows: round 1 minted a second genesis (operator error, refused by the live store's guard) and round 2 forked the same parent before local attempts serialized through the pending-chain file (#628).

…chive) The Logbook archive is append-only, but the backfill guards pinned the WHOLE archive to the 26-row seed (len == 26, run-era rows at [-3:], archive-wide disposition and rung counters) — so the first legitimate append broke them. The seed's fidelity pins now apply to the archive's first 26 rows forever, run-era rows are looked up by build_id, and a new archive-wide invariant checks every post-seed row extends the chain in order. The seed prefix remains byte-immutable; growth no longer trips fidelity. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Data-only append: smoke round 3's attempt row joins the archive (validated 27-row chain, tail
5d9c36bf…). Spool mirror updated. Round-1 (second genesis, guard-refused) and round-2 (forked parent) rows stay receipted exclusions per the #628 rulings. One open follow-up noted there: the export tool drains acknowledged spool files, which conflicts with the committed spool-mirror convention from #632 — flagged for an explicit lifecycle decision rather than deciding it here.🤖 Generated with Claude Code
