docs: changelog update 2026-07-04

[a5c-ai]

Automated daily changelog update

[a5c-ai]

Blocking this for now because the current PR head is red.

Blocker

• PR checks / GitHub Actions run 28694218620: the head validation is failing. gh pr checks 1137 reports failures in Docs QA, Lint, Tests, Package, and Workspace Coverage.
  • Docs QA failed during docs:build on a broken markdown link in docs/v6-spec-and-roadmap/security-architecture.md to ../policy-enforcement.md.
  • Lint, Tests, Package failed building @a5c-ai/comm-adapter because @a5c-ai/genty-core/trust and @a5c-ai/policy-adapter cannot be resolved.
  • Workspace Coverage failed building @a5c-ai/transport-adapter because @a5c-ai/trust-core and @a5c-ai/policy-adapter cannot be resolved.

Even though this PR only changes generated docs/changelog files, the review process requires rejecting when validation is failing. Please fix or rebase past the failing CI causes, then rerun checks. If these are known baseline failures, please document the exception explicitly before overriding.

Non-blocking cleanup

• CHANGELOG.md:43-44: the new section's final bullet is immediately followed by the next ## heading. Add a blank line between them.
• docs/daily-updates/2026-07-04.md:3-4: ## Summary of Changes is immediately followed by ### Features. Add a blank line for normal markdown section spacing.

Risk Assessment

Risk level: risk:medium

• Risk: CI red at the PR head means the repository is not proving this merge commit builds, tests, and renders docs successfully.
  Mitigation: require green CI before merge, or an explicit maintainer exception tied to known baseline failures.

• Risk: the generated daily report records CI statuses as pending/in progress, but later PR checks completed with failures.
  Mitigation: regenerate the daily update after checks settle, or treat the report as a timestamped snapshot and ensure the next daily update captures the failure/resolution accurately.

Blocking this for now because the PR head is red.

Blocker

• Required PR-head checks are failing. CI run 28694218620 for changelog/daily-2026-07-04 completed with failure. Failed jobs include Docs QA, Workspace Coverage, and Lint, Tests, Package.
  • Docs QA failed Docusaurus compilation because docs/v6-spec-and-roadmap/security-architecture.md links to unresolved ../policy-enforcement.md.
  • Workspace Coverage and Lint, Tests, Package failed TypeScript builds due missing module/type resolution for @a5c-ai/trust-core, @a5c-ai/policy-adapter, and @a5c-ai/genty-core/trust.

Fix or rebase onto a commit where the required checks pass, then rerun CI. If these are known base-branch failures, document that clearly and get an owner override before merge.

Minor

• CHANGELOG.md:44 follows the last 2026-07-04 maintenance bullet immediately with the next ## [Unreleased] - 2026-07-02 heading. Add a blank line between the list and the next heading for consistent markdown structure.

Risk Assessment

Risk level: risk:medium

• Risk: merging while PR-head checks are failing can mask docs-site build breakage and workspace typecheck failures.
  Mitigation: require a fresh successful CI run for this PR head, or an explicit owner override that identifies the failures as unrelated base failures.

• Risk: the daily update records transient CI statuses, so the CI Status Summary can become stale before review or merge.
  Mitigation: regenerate close to merge time, or add a generation timestamp in the automation so readers know it is a snapshot.

Live-stack QA was not dispatched because this PR only changes CHANGELOG.md and docs/daily-updates/2026-07-04.md; those paths do not match the process triggers for transport, launch, atlas graph, adapter, hooks, or SDK scenarios.

[a5c-ai]

Live-stack QA

Result: blocked. No live-stack workflow was dispatched. The selected matrix is empty because PR #1137 only changes generated changelog/daily-update docs, and the predefined process also passed the matrix-selection wrapper object rather than a matrix array into the dispatch command. Dispatching would be unrelated and malformed.

[a5c-ai]

Live-stack QA

Result: blocked. Live-stack dispatch skipped: PR #1137 only changes CHANGELOG.md and docs/daily-updates/2026-07-04.md, and the selected live-stack matrix is empty. No transport, adapter, launch, atlas, SDK/plugin, or hooks-mux path is affected.

[a5c-ai]

Live-stack QA

Result: blocked. Live-stack QA not dispatched: PR #1137 only changes CHANGELOG.md and docs/daily-updates/2026-07-04.md, and no focused live-stack agent/model/mode/install scenario applies. The selected matrix is empty because these docs/changelog paths do not exercise transport, provider, harness adapter, launch, atlas graph, SDK/plugin, or hooks paths.

[a5c-ai]

Reviewed PR #1137 adversarially as a docs-only daily changelog update.

Findings:

• Major: docs/daily-updates/2026-07-04.md:58 and docs/daily-updates/2026-07-04.md:80 report Live Stack as in_progress/pending for run 28694197098, but that run is now completed/failure. docs/daily-updates/2026-07-04.md:59 reports CI run 28694193720 as in_progress/pending, but that run is now completed/cancelled. Please refresh these status sections before relying on the report, or label them clearly as point-in-time snapshots with a generation timestamp.
• Minor: CHANGELOG.md:44 starts the next ## [Unreleased] - 2026-07-02 section immediately after the final 2026-07-04 bullet. Add a blank line there to preserve the surrounding changelog formatting style.

QA Dispatch passed: https://github.com/a5c-ai/babysitter/actions/runs/28729281441

Risk Assessment

Risk level: risk:low

The change is docs-only with low runtime blast radius. The main risk is audit/reporting accuracy: stale CI and live-stack statuses can make a failed run look pending. Mitigation: refresh or timestamp the generated status snapshot before treating this daily update as authoritative.

Live-stack QA

Run: https://github.com/a5c-ai/babysitter/actions/runs/28729373702

Matrix tested:

[]

Job	Result
Compute Matrix	pass
Build All	pass
Live Stack Report	pass

Overall verdict: failed. GitHub reports the workflow conclusion as failure even though the visible jobs listed above completed successfully. No live-stack scenario cells were selected for this docs/changelog-only PR, so the empty matrix should be treated as the likely reason to inspect before considering this QA pass.

[a5c-ai]

Adversarial review result: not approving or merging this PR right now.

The diff is docs-only (CHANGELOG.md and docs/daily-updates/2026-07-04.md), and I did not find a changed-file security or correctness blocker. The explicit qa-dispatch.yml run triggered for this review (28729299502) completed successfully.

Merge blocker: the PR CI run 28694218620 still has failing jobs: Docs QA, Workspace Coverage, and Lint, Tests, Package. Those failures appear outside the docs-only diff, but they still leave the PR in an unsafe merge state under normal branch policy.

Minor changed-file note: CHANGELOG.md:44 starts the next ## [Unreleased] - 2026-07-02 heading immediately after the previous bullet; adding a blank separator would keep the changelog formatting cleaner, though markdownlint reported 0 errors.

Risk Assessment

Risk level: risk:low for the docs diff itself.

Risks and mitigations:

• Required CI is red. Mitigation: fix or rerun the failing PR checks before merge; do not merge while branch quality gates are failing.
• The daily update includes transient CI/live-stack status snapshots. Mitigation: treat it as a dated 2026-07-04 snapshot or regenerate immediately before merge if current statuses are required.

Note: GitHub would not allow this token to submit a request-changes review because the PR was opened by the same app identity, so this decision is posted as a comment instead.
