Standing Decisions (ADR log) — {{repo.name}}

Status: Append-only decision log. Each entry is decided once; supersede with a new entry rather than rewriting history. Other docs point here rather than re-deriving the decision.

Authoritative location in this repo: {{docs.standing_decisions_path}}

How to use this log

Rule	Detail
Tier 2 decisions	Record here after recommend-and-confirm (see `policy/tiers.yaml`)
Append-only	Never edit or delete past rows; add SD-N+1 to supersede
Cross-link	Reference `SD-N` from roadmap, handover, and specs — do not copy rationale inline
Scope	Name affected repos/systems in Scope of effect

Decision authority (summary)

Full table: policy/tiers.yaml and {{docs.coordination_path}} (when present).

Tier	Behavior
1 — Standing defaults	Reversible, local, no live/external effect → just do it
2 — Recommend-and-confirm	Real trade-offs → propose + one yes/no → record here
3 — Hard gates	Irreversible / live / cost / security → always stop for operator authorization

Standing Decisions table (append below)

ID	Date	Decision	Rationale	Scope of effect
SD-1		Feature-branch commits (docs or code) are pre-authorized (Tier 1). Push-to-staging remains Tier 3. Merge-to-`{{vcs.git.main_branch}}` is Tier 3 by default; SD-21 carves finish-mode land hygiene after BV `pass`.	Commits on a branch are reversible and make work durable; uncommitted dirty trees are the riskier state.	{{repo.name}}; all feature-branch work
SD-3		Model-split handover prompts: steps marked Thinking → Auto emit `{step}a` (Thinking) then `{step}b` (Auto) in `{{docs.handover_path}}`. Single-model steps stay one prompt.	Opus on boilerplate wastes cost; Auto on security boundaries risks mistakes.	`{{docs.handover_path}}`; `{{docs.roadmap_path}}`
SD-17		Governance sync is a hard prerequisite for session complete. Closing commit bundles code/tests + `{{docs.roadmap_path}}` + `{{docs.handover_path}}`. Routine VCS hygiene (feature-branch commit/push/PR-open) is Tier 1.	Prevents stale handover/roadmap drift and over-cautious "ask before commit" friction.	{{repo.name}}; see `policy/tiers.yaml`
SD-21	2026-07-29	Finish-mode land hygiene after BV `pass` is Tier 1. When build-verification is `pass`, the feature is complete, and the diff has no live posture/env flip, secrets, real money, or Delegation write env: agents just do Muse merge/cherry-pick → `main` → muse-bridge → green `muse-mirror`→GitHub `main` (SD-14 only). Still forbidden: `git push origin main`, feature→GitHub-`main`, staging push, blind `--auto` merge.	Removes false land-ask friction; keeps SD-14 + live/security gates.	`policy/tiers.yaml`; muse+git-mirror consumers

Model-split protocol pointer (SD-3)

When a roadmap step's Model column contains →, the handover block follows:

Piece	Naming	Model	Delivers	Must NOT do
Part a	`{step}a`	Thinking	Contract, fail-closed rules, seven-tier test matrix	Implementation beyond types/contracts
Part b	`{step}b`	Auto	Mechanical impl to the frozen contract; run tests	Redesign the contract; widen scope

Regeneration: if {step}a is not done → handover lists {step}a only; if done → {step}b only.

See policy/model-labels.yaml for allowed labels.
