Extension history · past tense only

Everything we extended, and who asked for it

Four rounds. Each names its trigger honestly — manual CLI, or engine on a local timer. No row is labelled scheduled cron: as far as the record goes, the production cron has never extended anything.

5 September — calibration, disclosed

Three extend transactions placed B's crossing in-window, and the shared code was extended again while preparing C — 19 transactions that day in total, inventoried with every hash, unedited RPC response and explorer screenshot in docs/EVIDENCE.md § W1 inventory. Deliberate intervention, recorded as such: none of it is an unattended-engine proof. The table below carries the extensions that changed what the charts show; the inventory carries all of them.

The 9 September rescue found A nine days from archival and carried all three entries to December; its code entry still expires 20 October 2026 and is refused by the guard until W3-D18-02d. The 14 September save ran under a threshold raised to 1,500,000 — arranged timing, genuine response. "Charged" means decoded from the receipt; "as recorded" means the evidence record's fee column, not re-decoded here.
