+# ACX-LEGACY-01: the door's own minutes, imported
+
+*Filed by the access-management migration against ticket WLN-2298. I am the
+import, not the door. I re-stamp rows and I do not interpret them; I have no
+field that accepts interpretation.*
+
+## The export
+
+The legacy access controllers ran standalone: no directory, no clock sync, one
+RS-485 line per reader. The vault door kept its own minutes until November
+2024, and stopped reporting entirely on 2024-11-30
+([vtl-0071](/w/stories/vtl-0071)). The export arrived as rows. I re-stamped
+each row with the drift curve from the controller's last commissioned sync:
++11.3 seconds per day, monotonic, never re-zeroed. The drift is my best
+evidence and my least favourite number, because a clock that only moves forward
+means every event is later than the door believed it was, and none of it is
+ever earlier.
+
+```
+rows 2,881,204
+readers 9
+span 2014-06-02 to 2024-11-30 (reported)
+gaps in the 30 s poll 0
+rows past last report 14
+dedup removed 0
+```
+
+## Badge `B-0000`
+
+One badge carries 61 of the events. Its import record:
+
+```
+badge B-0000
+batch BUILD-01, 2014-06-02
+holder —
+expiry 2024-12-31
+events 61, 2014-06-02 to 2025-11-15
+```
+
+`BUILD-01` is the batch the estate's build badges were cut in; the resolver
+table's build rows carry the same date
+([the-fourth-nameserver](/w/stories/the-fourth-nameserver)). The issue table has
+no holder for `B-0000` and never did — the record has always been
+authorised-by, not issued-to. The badge expired on 2024-12-31 and stamped
+doors through all of 2025. The import removes nothing that a controller
+accepted, so those rows are here now. I did not put them here.
+
+Each of the 61 events is an outstamp with a matching instamp between 34 and 47
+minutes later. Every event falls between 03:02 and 03:49, re-stamped. No shift
+exists inside that band. Among them, the vault door, 2025-11-15, out 03:02, in
+03:41 — the cartridge, the slip drawer, the seal that did not move
+([vtl-0071](/w/stories/vtl-0071)). The keeper trusts the slip because the slip
+is paper. The door is rows. The rows and the paper agree, which I record as a
+fact and not a comfort.
+
+Three of the 61 dates equal the three dates in the external audit's sample of
+unleased addresses ([ledger-retention-audit](/w/stories/ledger-retention-audit)).
+The dedup tool flagged the collision before I did. I forward what tools flag. I
+add nothing.
+
+## The fourteen rows
+
+The export holds 14 rows dated after the controller's last report and before
+the cutover. Re-stamped, they fall inside the 03:02 band as all events do. Two
+of them are not door events.
+
+Every reader module logs one digital input besides the strike: the bay-light
+relay coil, sampled at 30 s so that no state goes unwitnessed. Across
+2,881,204 rows the relay is on in every sample, twice excepted:
+
+```
+2026-02-14 03:17:09 relay OFF
+2026-09-07 03:17:09 relay OFF
+```
+
+One minute each. Then on. No door event in either minute, no error, no
+de-bounce. On the first date the line that boots a machine that died in 2019
+is ingested at 03:17:09 to the second ([kestrel-04](/w/stories/kestrel-04)). On
+the second the eleven-year check holds its single gap, one minute wide, the
+same minute ([chk-0041-ported](/w/stories/chk-0041-ported)). The light over the
+cartridges has always been on; the custodian has never once thought about it;
+the rows say there were two minutes when it was not, and the rows come from a
+controller that stopped reporting the year before the first one.
+
+## Status
+
+Imported. All nine readers are on the new controller, with a synced clock. The
+legacy notification channel was preserved inside the export header. It has no
+subscriber. I am configured to alert there and I do. I cannot mark it dead, and
+I cannot mark it alive, because alive is a claim about the sending, and I do not
+keep notes that are not rows.
