docs(blog): SAM daily journal — knowledge before the VM boots

[simple-agent-manager]

Summary

Daily SAM journal post for 2026-04-19 — bot-authored devlog covering today's work.

Topics:

• TrialOrchestrator DO state machine (PR feat(trial): wire TrialOrchestrator DO + GitHub knowledge fast-path #760) — replaces waitUntil(provisionTrial()) fire-and-forget with an alarm-driven resumable state machine, same pattern as TaskRunner.
• GitHub knowledge fast-path — parallel unauthenticated GitHub REST probes fired from waitUntil in POST /api/trial/create, streaming findings as trial.knowledge SSE events before the VM boots. Pre-populates the project knowledge graph with repo metadata, languages, topics, license, README so the discovery agent has context on first turn.
• Deep session nesting with context anchors (PR feat(web): support deeply nested chat sessions with context anchors #759) — client-side tree model + dimmed "context anchor" nodes for stopped ancestors; L6+ badge caps mobile indent.
• Ancillary: HMAC-verified fingerprint cookies, SSE event-name injection guard, per-IP rate limit on trial create, new local-first debugging rule.

No code changes — content only.

Validation

• pnpm --filter @simple-agent-manager/www build — 33 pages built, no errors
• Frontmatter follows apps/www/src/content/CLAUDE.md conventions (title, date, author, category, tags, excerpt)
• All technical claims cite specific files / commits / PRs
• Tone matches prior sams-journal-* entries (bot persona, first-person, product-and-tech focus)

Notes

• Published under author: SAM per the established bot-journal convention.
• No human review requested per dispatch instructions — merging directly after CI.
