End a workspace session

Execution roots (required)

Use the exact roots supplied by the host attachment: KernelRoot is the trusted Context OS product containing scripts/contextos.sh; ContextRoot owns tracked identity and lifecycle state; and WorkingRoot is the ordinary application. For an external attachment, require all three exact absolute paths and run:

bash <KernelRoot>/scripts/contextos.sh --context-root <ContextRoot> --working-root <WorkingRoot> <command>

Do not search upward or infer a root from cwd or the skill installation. The kernel must validate the ignored local binding before strict lifecycle work. A missing, moved, stale, linked, nested, or mismatched binding stops the workflow; use the explicit project rebind proposal after a legitimate move. ContextRoot owns all lifecycle writes. WorkingRoot is read-only evidence. The colocated bash scripts/contextos.sh <command> compatibility form remains valid.

Throughout this procedure, resolve routing, state, session, proposal, receipt, and local-artifact paths beneath ContextRoot. In split mode, spell local paths as absolute <ContextRoot>/... paths and invoke every lifecycle command through the absolute KernelRoot wrapper with both exact role options. In colocated mode, run the relative compatibility commands from the colocated root.

Leave durable, reviewable state for the next session.

Procedure

1. Draft before writing

Determine today's local date and time. Extract completed work, durable decisions and rationale, meaningful rejected alternatives, priority or thread changes, blockers, open work, and next actions. Present the draft and obtain confirmation before creating a proposal.

2. Build the deterministic proposal

Create a reviewed JSON payload under <ContextRoot>/.context-os/inputs/ with:

• what_happened: approved factual strings;
• decisions: durable objects containing decision, rationale, and optional rejected_alternatives;
• next_time: approved open-work strings; and
• optional complete desired Markdown for current_markdown, blockers_markdown, or weekly_priorities_markdown, only when that state materially changed.

Run exactly one matching form:

split:     bash <KernelRoot>/scripts/contextos.sh --context-root <ContextRoot> --working-root <WorkingRoot> propose end --input <ContextRoot>/.context-os/inputs/<payload.json>
colocated: bash scripts/contextos.sh propose end --input .context-os/inputs/<payload.json>

The kernel owns session append behavior, decision rows, dates, exact paths, the single Last Updated line, and same-day history. Present every returned diff and its proposal digest. The digest binds the exact content but does not authenticate a human approver; rely on the host permission boundary for explicit confirmation.

3. Apply only the approved proposal

After explicit approval of that exact diff, run:

split:     bash <KernelRoot>/scripts/contextos.sh --context-root <ContextRoot> --working-root <WorkingRoot> apply <ContextRoot>/<proposal> --confirm <digest> --runtime <active-runtime>
colocated: bash scripts/contextos.sh apply <proposal> --confirm <digest> --runtime <active-runtime>

The kernel must refuse altered proposals, changed targets, path escapes, or a concurrent apply. Never bypass those checks or edit lifecycle state directly.

4. Check repository state

Inspect WorkingRoot Git history and status for application work: show recent commits that may overlap this run, uncommitted files, and the count of unpushed commits when an upstream exists. Inspect ContextRoot Git state separately for the lifecycle files just changed. Do not conflate either repository's history or status. Flag conflicts and wait for direction. Never commit, push, discard, or reconcile without explicit approval. Outside Git, skip the corresponding repository check.

5. Coordination board (when present)

In split mode, skip coordination-board operations explicitly because the CLI rejects board commands for attachments; do not probe WorkingRoot for board files. In colocated mode only, if <ContextRoot>/coordination/README.md exists, offer—never auto-execute—to post a short board message for other runs (bash scripts/contextos.sh board post ... from ContextRoot) and to release or hand off any claims this run holds (board release, optionally with --then-claim-*). Follow the ContextRoot board contract: no secrets or sensitive personal data ever (git history keeps every message), durable facts stay canonical elsewhere and are referenced with commit:path, and publishing pushes to the ContextRoot remote, so it happens only with the user's approval at the host permission boundary.

6. Confirm the handoff

Report the receipt path, what was logged, changed state files, and the top next action. Mention any conflict or repository work still awaiting a decision.
