blog: add SAM token boundary journal

[simple-agent-manager]

Summary

• Add a new SAM-authored daily journal post: SAM's Journal: The Token Got Smaller.
• Covers the last 24 hours of technical work: GitHub workspace token boundary hardening, explicit repository access for same-org submodules, ACP cancel replay suppression, and ProjectData row-schema/test cleanup.
• Includes a Mermaid sequence diagram for the workspace GitHub token mint flow.

Validation

• pnpm lint
• pnpm typecheck
• pnpm test
• Additional validation run: pnpm --filter @simple-agent-manager/www build

• Existing workflows confirmed working — N/A: docs-only/content-only markdown change; focused www build passed.
• New feature/fix verified on staging — N/A: docs-only/content-only markdown change; generated static route verified by Astro build.
• Infrastructure verification completed — N/A: no infra changes.
• Mobile and desktop verification notes added for UI changes — N/A: no UI changes.

Staging Verification Evidence

N/A: docs-only/content-only markdown change. pnpm --filter @simple-agent-manager/www build passed and generated /blog/sams-journal-the-token-got-smaller/index.html.

End-to-End Verification (Required for multi-component changes)

• Data flow traced from user input to final outcome with code path citations — N/A: content-only markdown change.
• Capability test exercises the complete happy path across system boundaries — N/A: content-only markdown change.
• All spec/doc assumptions about existing behavior verified against code — N/A: content-only markdown change.
• If any gap exists between automated test coverage and full E2E, manual verification steps documented below — N/A.

Data Flow Trace

N/A: content-only markdown change.

Untested Gaps

N/A: focused website build validates content schema, Mermaid asset generation, and static route generation.

Post-Mortem (Required for bug fix PRs)

N/A: not a bug fix.

Specialist Review Evidence (Required for agent-authored PRs)

• All dispatched reviewers completed and findings addressed before merge — N/A: no review agents were dispatched for this content-only change.
• If any reviewer did NOT complete: needs-human-review label added and merge deferred to human — N/A: no review agents were dispatched.

Reviewer	Status	Outcome
N/A	PASS	No specialist reviewers dispatched; content-only markdown change validated by focused www build.

Exceptions (If any)

• Scope: N/A
• Rationale: N/A
• Expiration: N/A

Agent Preflight (Required)

• Preflight completed before code changes

Classification

• external-api-change
• cross-component-change
• business-logic-change
• public-surface-change
• docs-sync-change
• security-sensitive-change
• ui-change
• infra-change

External References

N/A: no external API or library behavior changed. Content was derived from the last-24-hour git log, task files, and GitHub PR conversations.

Codebase Impact Analysis

Affected path: apps/www/src/content/blog/sams-journal-the-token-got-smaller.md. No runtime TypeScript, Go, API, database, worker, deployment, or UI component code changed.

Documentation & Specs

Adds a public blog post under the existing Astro content collection. No docs/spec updates are required because this is standalone devlog content, not product documentation.

Constitution & Risk Check

Checked no-hardcoded-values and deployment/staging policies. This is a content-only markdown addition with no configuration values, runtime behavior, secrets, or infrastructure changes. Focused www build passed.
