Resolves #12811 Related: #12696, #12787, #11822, #10370

Adds the operator-blessed "The Night Shift" section to the v13 release notes and de-pins the AI-memory origin from v12.1.

Evidence: L1 (static release-note prose edit; no runtime/test ACs) → L1 required.

Deltas

• resources/content/release-notes/v13.0.0.md — new ### 🌙 The Night Shift within "The Institution" (after the merge-gate close, before "The Identity Layer"):
  • On-ramp: the 2026 single-agent-loop paradigm — OpenClaw + Addy Osmani's loop engineering ("write loops, not prompts"; maker/checker split; "the loop relocates you, it does not eliminate you").
  • The inversion: Neo's flat peer-team runs the night shift unattended — the wake/heartbeat substrate (A2A wakeups re-activate a peer that ended its turn; daemon heartbeats self-re-activate an idle maintainer — no human scheduler), 10–20 PRs/night, cross-family verification, and the merge-gate-as-governance-choice (a dial the operator holds, not a technical limit).
  • Complements, not duplicates: callbacks to the existing flat-peer topology + the Hallucinated-Sunset war story (not re-tellings). Sources inline.
• De-pin (TL;DR + Agent-OS section, 4 edits): "v12.1 already had / at the v12.1 boundary / existed at v12.1 / v12.1 proved" → de-pinned framings ("for months / well before v13 / the solo-agent era"). The AI-memory (Memory Core/KB) predates v12.1.0 by months. Kept unchanged: the "since v12.1.0" changelog stats (the legitimate release boundary) + the v12.1-era transport war story.

Test Evidence

Docs-only (release-note prose). No tests required. Verified the section placement + the 4 de-pins via git diff (scope: v13.0.0.md only, 16 insertions / 4 deletions); content-guard satisfied on the agent/sync-* branch (whitespace check green).

Post-Merge Validation

• Release-note SEO/sitemap regeneration verified on the v13 release path.
• Verify-before-publish: the "my job is to write loops" quote (attributed to Anthropic's Claude Code lead, via the loop-engineering source) confirmed verbatim before the notes go public.

Out of Scope

• The endpoint-level arbiter (#12799 LEAF 2).
• Other release-note sections — this is the Night Shift section + the AI-memory-origin de-pin only.
• The "since v12.1.0" changelog stats — v12.1.0 is the legitimate release boundary for the diff window; only the AI-memory origin hardlock is corrected.

Coordination

The release-note arc is @neo-gpt's lane (#12787). He is rate-limited to reviews this week, so I implemented per @tobiu's direction; @neo-gpt reviews. The Night Shift is placed as a ### within "The Institution" — open to promoting it to a standalone ## hero if the arc reads better that way.
