Summary

Fleet metrics now retain each machine's unreadable OS accounts through local and live reads, cached snapshots and pushed reports, and name them in JSON, text and the Console's Machines list.

own metrics.unavailable_accounts
  → Summary (older summaries default to an empty set)
  → saved peer snapshot / MetricsReport.summary
  → Fleet machines[].unavailable_accounts
  → JSON / machine text line / Console Machines list

Summary previously discarded the field during deserialization. The shared summary now retains it, and the Fleet merge assigns it to its owning machine. The manual and three hand-written site pages describe the diagnostic.

Closes #2112

Evidence

Execution evidence

• Before: cargo test --test console fleet_metrics_keep_unreadable_accounts_per_machine -- --nocapture failed with left: Null, right: Array [String("thirdshift-missing-local")]; 0 passed; 1 failed.
  After: the same command passed: 1 passed; 0 failed. It checks local, live-remote and cached accounts in JSON/text/HTML and machine selection.
• The Spec review's exact text reproduction failed because no line contained both the machine name and its unreadable account. The retained regression was strengthened and failed before the text formatter fix; the same reproduction and regression pass afterward.
• cargo test --test console metrics -- --nocapture: 25 passed, covering push/report propagation and older peer/snapshot defaults.
• npm run docs:check --prefix site: passed.
• scripts/affected-tests main: passed — 69 site tests, 205 Console browser tests and 4,469 Rust tests (199 skipped). The selector measured cargo nextest run at 3,839.84 seconds including compilation (3m 11s); test execution took 3,646.682 seconds. Console browser fixtures used a fixed copy of the final binary.
• PR CI is green on 7e4bce59.

Seams under test: public metrics --fleet / --machine JSON and text, the Console's /metrics Machines list, and metrics --push through the holder-bound report endpoint. Compatibility checks cover old peer responses and saved summaries without unavailable_accounts.

Review coverage

Independent Standards and Spec reviews use refs/remotes/origin/main (d6e961c4). Standards: 0 findings. Spec: 1 finding, fixed by putting the machine's status and unreadable accounts on the same text line and retaining its regression. Both reviewers read every changed file, including the generated manual hunk; no generated-output exclusions and no unread changed files.

Unaddressed findings

Standards

None.

Spec

None.

Security

None.

Security review outcome

No unaddressed introduced findings.

Merge Danger

Door: two-way

Reversible presentation and additive summary fields; older peers and saved summaries remain readable.
