Changelog

Dated and honest, including the fixes. Metrics quoted here are reproducible from the live console and the signed artifacts each entry shipped with.

2 September 2026

Public read-only console: last night's alert stream, catalog churn and graded detection rates with no sign-in.
Interface refresh: the operator dashboard moves to a violet glass theme; severity and orbit-class colours unchanged.
Application audit trail: every mutating API call is recorded to a tamper-evident internal log (ISO 27001 groundwork).
Per-route latency monitoring with a p95 alarm on the public API.
Decay-by-silence evidence on alert cards: silent-gap length, cadence ratio and perigee now render inline.

26 August 2026

The terminal-silence detector, built on the insight that objects which stop being catalogued at low perigee are often about to re-enter, now feeds the fused score, the API enrichment and signed forensic dossiers.
Every silence-promoted alert ships with an HMAC-signed dossier; previously eight alerts lacked one.

23 August 2026

A flight recorder logs every pipeline subtask (exit code, runtime, peak memory) to a daily manifest.
An expectations engine checks hard contracts (ledger monotonicity, receipt integrity, publication completeness, feed liveness) and statistical baselines every day, and publishes a verdict that pages us, not you, when something drifts.
Artifact schema validation now runs inside the production pipeline, not just in CI.

18 August 2026

S3-backed feed cache: upstream outages (Space-Track, Celestrak) degrade gracefully to the last live copy instead of failing the run.
Day-close verification: the pipeline now proves every expected artifact was actually published before calling a day done, and alarms when it can't.
Prediction-ledger grading made sticky: a confirmed outcome can never silently flip back when the upstream feed's rolling window forgets the event.

early August 2026

API keys with per-tier entitlements, usage quotas and the public REST API.
HMAC-signed forensic dossiers for every alert.
Prediction ledger with hash-chained receipts: every call recorded before the outcome, graded after, tamper-evident.

July 2026

DebrisGuard begins issuing prospective, dated predictions (manoeuvre cadence and decay) into a public graded ledger, the foundation of "numbers you can check".
