Full details: Description checkExplanation The description provides a clear summary, validation details, and a completed agent preflight. However, it omits required template evidence: the staging section does not state “N/A: docs-only,” and the specialist-review and CodeRabbit evidence sections are not completed. Resolution Add “N/A: docs-only” with an explanation in Staging Verification Evidence. Complete the specialist-review table or state “N/A: human-authored PR” if applicable. Record the CodeRabbit review outcome in CodeRabbit Notes, or state “N/A: human-authored PR” if applicable.

The initial CI run evaluated the PR body before the required preflight block was added and failed Preflight Evidence. I corrected the live PR body at 15:12 UTC; the running Marketing Site job is still completing. A fresh run is needed to reevaluate current PR body evidence. |
|
Review/CI evidence update (2026-10-04 UTC): CodeRabbit was requested through the label; its run succeeded, but the bot still reports review in progress with no findings posted. The PR-triggered Marketing Site check passed lint, typecheck, build/link check, and 206 desktop/mobile browser tests. Preflight Evidence failed against the initial PR body before the required template block was added; the corrected block is present in the current body. A workflow_dispatch rerun skips this PR-only gate, so I am cancelling that redundant run and rerunning the PR CI against the current body. |

- Line 18: Update the recovery-point sentence in the blog content to describe
the exact commit and uncommitted changes as required, and qualify branch
information as present only when the repository is not in detached HEAD.
- Line 20: Add a brief excerpt from the actual snapshot-retry implementation
before the Mermaid diagram, and link the excerpt to the specific source file
rather than the repository homepage. Keep the example focused on the retry
behavior described in the post.

| By default, I try a full snapshot three times or for 15 minutes. The limit is stored with the session, so a Worker restart or a repeated background check does not reset it. | ||

| If those tries fail, I look for an earlier snapshot that contains a real Git recovery point: the repository's exact commit and branch, plus its uncommitted changes. I also check that the files needed to restore that point were retained. A commit name by itself is not enough; the commit's contents must still be available. |

Qualify the branch claim for detached-HEAD snapshots.
When a snapshot passes the recovery-point checks, the assessment can return ok: true with branch: null if its manifest marks it as detached. The sentence promises a branch in that case. Qualify the branch claim:

Add an implementation example before the diagram.
This technical post explains snapshot retries and Git-based recovery, but its Mermaid diagram does not show implementation code. Its source link points to the repository homepage, not a specific file. The blog guide calls for early code examples in technical posts and references to specific files. Add a short excerpt from the real retry implementation and link to its source file.

Codebase Impact Analysis
Only
apps/www/src/content/blog/sams-journal-a-safe-place-to-stop.mdis added. No application code, interfaces, or runtime behavior changes.Documentation & Specs
Added the public engineering journal post in
apps/www/src/content/blog/. Existing session recovery documentation already describes the bounded retry and fallback behavior.Constitution & Risk Check
Checked that the post makes no new runtime claims beyond the implementation and troubleshooting guide. It clearly explains that changes after the recovery point may be missing and that SAM leaves the workspace running if it cannot verify a safe restore point.
