After PRs #34–#39 merged, the roadmap still contained obsolete publication instructions. Reconcile the Unreleased notes, plan, handoff and evidence ledger with the integrated source while keeping the published 0.4.0a1 release unchanged. Make evidence-based agent engineering an explicit requirement of the active goal: research and reuse, bounded acceptance, scoped collaboration, meaningful validation, independent review, protected integration and reproducible handoff. Keep the primary OpenAI/Anthropic references in the repository.

Record main-branch protection and refresh the target-specific upstream ledgers. These changes do not extend the qualified recovery boundary or claim successful OS-reboot continuation.

Two original Windows jobs exposed test-fixture timing assumptions. Reuse the logical observation-clock pattern for one ordinary continuation test and the existing 30-second whole-fixture join guard. Keep that guard at module scope so fixtures that borrow the helper also work. Preserve all original failures and exact predecessor bytes; connect the corrected fixtures to the existing historical-source reader without weakening its assertions. Production runtime, freshness, execution clocks and task allowances remain unchanged.

Validation for 142a838de9cd8f41a1f027c13578301f11077bb7:

• Independent review cleared the changes and checked every active helper alias/caller. Twelve focused successor checks passed: all six direct and both aliased calling tests, three archive-integrity regressions, and the originally failing compiler source assertion. The retained test process joined normally; no timeout or source changes occurred during validation.
• The earlier twelve-test timing pass, separate failed hosted runs and incomplete local historical-reader sweep remain recorded. That sweep logged 118 of 145 checks before its original outer guard expired; its remaining 27 checks are not claimed as passed. No failed run was rerun or relabeled.
• Fresh document checks passed for 18 changed files, including 343 local links, 54 anchors, JSON/source pins, citations, private paths and whitespace. Fresh distribution verification covers all 1,424 source files, with actual Git blobs matching the checkout and packaged snapshot. All 88 wheel payloads, including all 77 runtime modules, match the retained automatic-recovery package.

The source-bound fixture record preserves the original failures, corrections, evidence hashes and scope. Full original hosted checks on this new head must pass before merge. No new binary release, inference/physical rerun or unrelated upstream progress broadcast is included.
