docs(remediation): finalize — reframe to completion + record all outcomes

[ProtocolWarden]

Closing PR for the incomplete-integration remediation campaign (14 green-gated PRs).

Updates the plan of record to the completed state, reframed around the operator's mid-campaign correction — complete genuine features, don't delete them — and records every outcome:

• 3 adversarial corrections that caught the per-repo audit's blind spots (cross-repo consumers, indirect dispatch, convention hooks).
• WIREs: DAGExecutor Add tests for client.py #10, SwitchBoard Polish public docs packaging: operator runbook, README completeness #21 (p95 demote), PlatformManifest fix(ty): clear all 21 pre-existing diagnostics; flip ty CI to blocking #83 (visibility_scope fail-closed), and the OC observer plane — feat(observer): wire FlakyTestReporter into the live pytest plugin #325 (FlakyTestReporter), feat(observer): wire CoverageTrendManager + CoverageAlertManager into the service #326 (coverage trend/alerts), feat(reviewer): surface merge-decision metrics (wire export_metrics_json) #327 (merge-decision metrics).
• Deletes of superseded duplicates only (Custodian Verify Address repeated validation failure failures #47, DAGExecutor Verify Address repeated validation failure failures #11, SourceRegistry Follow up on WIP/temporary commits #14, TeamExecutor Follow up on WIP/temporary commits #12, CoreRunner Promote golden-path demo as ongoing trust-building ritual #20); ContextLifecycle = KEEP.
• The d12_baseline ratchet pruning (D12 gate confirms 0 after each wire).
• The B2 root cause: content-less secret artifact (infra, not a code bug) — diagnosed read-only.

Self-review concerns — auto-fixing (up to 6 attempts; re-queued if still unresolved):

PR count discrepancy: backlog.md claims '14 green-gated PRs' but the design document lists and documents only 12 distinct PRs (1 backbone + 6 WIRE + 5 DELETE). The enumeration is clear in the design doc but the count in backlog.md is off by 2. Either correct the backlog to '12 green-gated PRs' or document the 2 missing PRs in the design doc. All other content is well-structured, coherent, and properly transitioned from in-progress plan to completed outcomes.
