New pillar post extending action authority to the merge / deploy surface. The corpus's coding-agent treatment stops at file-write / shell-exec / DB-call; Devin, Codex Cloud, and Claude Code (yolo and Auto modes) now sit one layer above, pressing the merge button and triggering deploys unsupervised. The post frames merge/deploy as a distinct action class with structural irreversibility, fan-out blast radius, trust elevation, and a distinct audit unit. Places merge operations in the risk-assessment 0-4 tier model with scope-aware tiering (feature branch, non-protected, protected, auto-deploys-staging, auto-deploys-prod). Provides a RISK_POINTS schedule for merge operations, a reserve-commit pattern with merge-specific caps (requires_human_approval, requires_distinct_ approver, max_merges_remaining, deploy_gate: deferred), and mirrors the two-layer PocketOS argument (branch-protection scoping + agent-side runtime authority). Internal cross-links to ai-agent-action-control, ai-agent-risk- assessment, agent-memory-writes-are-actions-too (sibling extension), ai-agent-deleted-prod-database, pocketos-aftermath, coding-agents-need- runtime-authority, least-privilege-api-keys, and the relevant protocol and glossary pages. External citations: Cognition's Devin merge stats (how-cognition-uses- devin-to-build-devin, 2025 performance review), Anthropic Auto Mode launch, OpenAI Codex Cloud docs. Reviews: internal cycles 1-3 (scorecard 9.3/10), glossary linker added 9 contextual links.
Apply/skip tally: 6 applied, 2 pushed back. Applied: - Description overclaim: "now merge PRs and trigger deploys unsupervised" overstated — Codex Cloud creates PRs but team merges through normal flow; Devin PRs typically auto-merge via branch protection. Reworded to "reach the merge button — direct call or auto-merge via branch protection. Treat merge as a tiered action." (151 chars, within 150-160). - L30 incident class: Anthropic's Auto Mode page doesn't cite a recurring `rm -rf` / `~/` incident class. Reworded to "destructive shell, branch-deletion, and migration incidents" matching what Anthropic actually cites. - L32 framing: softened "they... merge to main and trigger deploys" to "they... press the merge button or satisfy the conditions that auto-press it" — distinguishes direct-merge from branch-protection auto-merge. - L48 Codex Cloud framing: clarified "the team merges through its normal flow" so the agent-vs-team merge distinction is explicit. - L86 "pattern that exists in production today": softened to "a pattern teams have reported using to clear small-style or lint-pass checks" — adds context without overstating prevalence. - L155 GitHub bypass_pull_request_allowances: narrowed to clarify the API allows bypassing review requirements, which is "adjacent but not the same thing" as distinguishing bot reviews from human reviews. - L192 "Many teams today are likely": hedged to "In our experience, teams that have invested heavily in branch protection..." Skipped, with reason: - Body cross-link count exceeds 5-8: same argument as memory post — most flagged links are glossary auto-links that clarify terms in-place, not topical cross-references. Topical body cross-links number ~7, within target. - "Yolo mode" in metadata/table: this is the widely-used community shorthand for `--dangerously-skip-permissions` and a key SEO term; Anthropic's own Auto Mode blog uses the framing. Defensible. Codex verified: Devin 659/154 figures and 34%/67% merge-rate doubling against their respective Cognition source pages; Claude Code Auto Mode is Sonnet-based per-tool-call classifier; GitHub branch-protection API field exists; --dangerously-skip-permissions is the real flag.

Moved from 2026-05-18 to 2026-05-23 (one week after the memory-writes sibling) to match a weekly publishing cadence for the action-authority extension arc instead of the original near-daily sequence.

Summary
New pillar post extending action authority to the merge / deploy surface. Corpus's coding-agent treatment so far stops at file-write / shell-exec / DB-call; Devin, Codex Cloud, and Claude Code (yolo + Auto modes) now sit one layer above, reaching the merge button either directly or by satisfying the conditions that auto-press it.

This post links to `/blog/agent-memory-writes-are-actions-too` (the sibling extension post). That post is on PR #648 and should be merged first so the cross-link resolves.
