Cursor session bookends (LT slice 2)

When session_bookends.enabled: true in .overseer/config.yaml, ok sync / ok init vendors the full hook bundle into .cursor/hooks/:

Default: session_bookends.enabled: false — hooks are not footprint members unless the flag is on (ONS §LT.4.4 narrow supersession).

Behavior (frozen §LT.4.5)

• sessionStart / stop: run session-start-next.sh → ok next body + workspace-root + stale-tab honesty (fail-open JSON).
• sessionEnd: run session-end-closeout.sh → ok governance-sync --dry-run then ok next (never --write; never claim tab reload).
• failClosed: always false — hooks never block DONE.

Manual merge (existing .cursor/hooks.json)

If a consumer already has hooks, sync classifies like any footprint file (missing → seed; both-changed → no clobber without --force). No JSON deep-merge in Auto v1.

cursor/hooks/print-next-stop.json remains the ONS snippet for hand-merge of stop only.

Portable primary (unchanged)

Missing Cursor hooks is not pass and not fail — degrade to CLI.
