The Full-System Audit Campaign

Between 5 May 2026 and 4 July 2026, LisaOS put itself through a full-system audit. The campaign had four phases — audit, triage, remediate, document — and the site you are reading is its final deliverable.

Phase 1–2: Audit and triage — 235 findings

By 5 May 2026 the audit and triage phases were complete. A whole-system sweep produced 235 findings, severity-split as:

Triage sorted the 235 into a remediation backlog, each finding tracked as an issue with an owner and a severity that determined how urgently it had to close.

Phase 3: Remediation — the long tail

Remediation ran across May and June as a series of thematic waves — security hardening, compiler and type hygiene, governance tightening, the skill ecosystem, test coverage, and a final parity-verification pass. The critical findings were the gating set: Phase 3 could not close while any critical remained open in production.

The tail narrowed to a single genuine finding. Empirical re-verification of the suspected-open backlog established that most of the apparently-open critical tickets were cascade-close drift — already resolved but never marked — and that exactly one critical finding was still failing in production: a datastore-backup control that had been failing silently against a script that never existed. On 10 June 2026 that control was shipped end-to-end through the full change pipeline — scoped, dual-reviewed, implemented against the existing backup repository, and restore-tested live — with verification confirming its failure alert genuinely fires. The silent-failure mode was structurally cured, and with it the last critical finding closed. Phase 3 was unblocked.

The formal Phase 3 gate followed: a clean reconciliation run, zero open critical findings, and operator sign-off.

Phase 4: Documentation — this site

Phase 4 was the documentation arc: a rewrite of the architecture specification and the construction of this public documentation site from vault ground truth. It shipped in waves:

Every page is derived from the vault and passes through a fail-closed sanitisation gate before it can be built or deployed. Infrastructure coordinates are generalised or withheld by design; the architecture, protocols, and governance are the content.

Case study: the gate that caught what it was built to catch

The sanitisation gate is not decorative — and the clearest evidence is that it fired on real material. During the second documentation wave, the gate blocked a build because source content carried a class of operator personal data that must never reach a public page. The gate did exactly what a fail-closed control is supposed to do: it refused to build rather than publish, named the offending class, and forced the coordinate to be generalised before the wave could proceed.

The detail worth recording is the class, not the instance — which is why this entry names neither what was caught nor where. That restraint is itself the discipline: even the record of a sanitisation catch is written so that it does not re-leak the thing that was caught. A gate that you can only trust when it stays quiet is not a gate; this one earned trust by going off.

Where it landed

The campaign closed on 4 July 2026 with the documentation phase complete. What began as a defensive exercise — find what is broken before it breaks — ended as a constructive one: the system now has a public, sanitised, navigable account of its own architecture, and a fail-closed pipeline that keeps that account honest as it evolves.
