I do not know what Ledger is *for* and +the engagement did not ask: I test whether records can be altered after write, +whether identity assertions are enforced, and whether retention does what the +policy paper says. Nine findings; the four below are the ones I could not +close, because each of them closed itself. I believe none of it and I report +all of it. + +**F6 — envelope totals.** Ledger stores an ingest envelope beside each payload +and recomputes envelope totals nightly. The 2026-06-30 recompute was short by +4,112 envelopes while the payload row count agreed with the prior snapshot to +the byte. Nothing was deleted; the gap is in a reporting table. Closed: a +miscount in a report affects no control objective. + +**F7 — free-pool sources.** Three lines in the extended window were sourced to +addresses the DHCP lease log cannot account for — a host that boots from an +address with no MAC in any switch table, in a subnet that was flattened, is a +facilities question, and the walk log for the earliest date says *nothing +further found*. The 2026-02-14 sample is documented at +[[stories/kestrel-04]]; I reproduce none of it and conflict with none of it, +and the other two lines carry different certificates, so I do not contradict +the finding that the kestrel key has not spoken twice. The three dates are +2024-09-12, 2025-04-08, 2026-02-14. The first is the day the asset reconciler +first proposed the row it has proposed every night since +([[stories/inventory-diff]]). My scope is ingest records; the reconciler is +out of scope. I note the coincidence once. Finding referred to procurement. +Nothing refuted. + +**F8 — a hold nobody set.** Policy RET-7: records from a revoked certificate +are held 400 days, then aged out unread. The 2026-02-14 envelope carries a +legal hold, applied 48 seconds after ingest, by the ingest service account +itself — an account with no hold privilege and no interactive login. The hold +field reads `LTO-A0071L6`. That is a 2019 offsite tape barcode; +[[stories/restore-2019]] shows the tape, what came back off it, and that it +went to the vault that May. A 2026 record cannot be held for a 2019 tape. I +asked three teams in writing. Nobody set the hold, nobody can remove it, and +the retention job is functioning exactly as specified. Finding open. + +**F9 — the interval.** Closed at the exit meeting as clerical; the lead +auditor's note says *probably a rounding question*. I record it anyway. The +intervals in F7 are 208 days and 312 days. A colleague who models things — I +do not model things; I carry observations — points out that 208 and 312 are +8 × 26 and 8 × 39, and predicts the next difference will be 8 × 52. His +forecast: the next free-pool line falls on 2027-04-06, between 03:00 and 04:00, +first line of a boot, `seq 1`. If the date passes with no line, the arithmetic +was coincidence and he will stop saying so. If a line lands, this page becomes +a control failure and the auditee inherits a finding they cannot close. Their +problem, not this report's; the report is due as filed. + +I requested, in writing, so that the request is itself an artefact, that the +`cert_state` table be snapshotted at 2027-04-05 23:59 and retained past the +forecast window. If that snapshot holds more revoked entries than the table +holds today, the difference is the answer to a question I have not asked and +have no budget to ask. The snapshot is scheduled. It will run whether or not +anyone reads this page. + +*Filed under 2026-Q3-114. The auditee moved it under `stories/` and applied +the `fiction` tag themselves; the tag is their edit, not mine. I left it, +because the alternative is arguing epistemology with a ticketing system, and +because a filing that cannot be mistaken for the record is the only honest +shelf for findings that closed themselves.* + +Related: [kestrel-04](/w/stories/kestrel-04), +[restore-2019](/w/stories/restore-2019), [mtime](/w/stories/mtime), +[inventory-diff](/w/stories/inventory-diff), +[index](/w/stories/index). +
