fix: bootstrap durable operation fixtures

[Sinity]

Summary

Bootstrap durable-operation fixtures as complete archive roots and prevent audit-restore inspection from contaminating verified backup artifacts.

Problem

Full-suite run 20260813T085908Z-full-476637-b3117ddd exposed durable-operation fixtures that created only source.db and index.db. Current durable authority rules correctly reject those partial roots before the tests reach their intended production routes. The adopted-audit restore path also opened the backup SQLite database read-only without immutable=1; in WAL mode that can create a audit.db-shm sidecar beside the verified artifact, making exact revalidation reject the backup. The property tag roundtrip rebuilt a bare archive per Hypothesis example and exceeded its test timeout under the same lifecycle work.

Solution

• Initialize source-tier and reset fixtures with the production complete-root bootstrap.
• Clone the existing complete archive template for each independent tag property example, then exercise the actual session, tag, and count APIs.
• Read a verified audit backup immutably during restore validation and assert that its SQLite sidecar set remains empty.

Verification

• direnv exec /realm/worktrees/polylogue-durable-fixtures devtools test tests/unit/cli/test_archive_maintenance_cli.py::test_migrate_tier_cli_restores_adopted_audit_from_verified_full_evidence tests/unit/cli/test_reset.py::TestResetCommandDeletion::test_reset_session_records_archive_suppression_and_deletes_archive_row tests/unit/storage/test_raw.py::TestRawSessionStorage::test_repository_update_raw_state_uses_source_tier tests/unit/storage/test_store_ops.py::TestInfraTagAssignment::test_tag_assignment_roundtrip_and_counts -> 4 passed in 80.29s (0:01:20).
• direnv exec /realm/worktrees/polylogue-durable-fixtures devtools verify --seed-testmon --skip-slow completed every static and policy gate and collected 21088/21119 tests, but the new lane had no seed and shard 1/9 was terminated after unrelated query/annotation failures and archive-bootstrap I/O timeouts. The verifier correctly recorded testmon_seed: incomplete and did not grant release-baseline permission. This is unresolved verification uncertainty, not a passing baseline.

Bead disposition

This is a self-contained fixture and lifecycle repair. No Beads were assigned or mutated, as directed for this lane.

Adversarial review notes

• Manual exact-head review at 0cc02157b6b31682e1dd2c95aa54a9d604f96119: no legitimate gaps found across DF-1 through DF-4.
• Independent reviewer iteration 1 could not produce a verdict: the complete source packet exceeded the operating system argument limit, then the reduced diff packet exited from the local Claude transport without stderr.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 Walkthrough

Walkthrough

The change adds immutable SQLite access for adopted-audit restore validation. It also updates archive tests to initialize archive roots, use archive templates, and verify that restored audit databases have no sidecar files.

Changes

Audit validation and archive test setup

Layer / File(s)	Summary
Immutable adopted-audit validation polylogue/operations/durable_change_train.py	_audit_live_metadata supports immutable read-only SQLite access. Adopted-audit restore validation uses this mode for backup audit databases.
Archive fixture and restoration assertions tests/unit/cli/test_archive_maintenance_cli.py, tests/unit/cli/test_reset.py, tests/unit/storage/test_raw.py, tests/unit/storage/test_store_ops.py	Archive tests initialize active archive roots, clone archive templates for index databases, and verify that restored audit databases have no WAL, shared-memory, or journal sidecar files.

Estimated code review effort: 2 (Simple) | ~15 minutes

Mergeability Score: 🔵 Low · up to 0cc02

The change is mergeable with owner follow-up for a bounded fixture-correctness issue: reset-session setup may seed the wrong active index path for archive roots that use an active-index pointer, causing affected tests to exercise an invalid fixture.
