+# Decision Log
+
+Structured, append-only decision records for `tegwick-control`.
+
+## Purpose
+
+Decisions that affect activation levels, commitments, governance, or landscape
+priority belong here — not only as inbox notes or task bullets.
+
+## Layout
+
+```text
+decisions/
+├── README.md                    this file
+├── DEC-NNN-<slug>.md            individual decision records
+└── archive/                     superseded records (optional)
+```
+
+## Naming
+
+```text
+DEC-NNN-<slug>.md
+```
+
+- `NNN` — three-digit sequence (`001`, `002`, …)
+- `slug` — short kebab-case topic (`activation-levels`, `root-control-repo`)
+
+## Registry
+
+`DECISIONS.md` at the repo root is the **index**: open decisions, resolved
+decisions, and pointers to full records in this folder.
+
+When creating a new decision:
+
+1. Allocate the next `DEC-NNN` id from `DECISIONS.md`.
+2. Copy `templates/decision-record.md` into `decisions/DEC-NNN-<slug>.md`.
+3. Add a summary entry to `DECISIONS.md` under Open or Resolved.
+
+## Status values
+
+| Status | Meaning |
+|---|---|
+| Open | Under consideration; no choice yet |
+| Accepted | Decision made and in effect |
+| Rejected | Option explicitly declined |
+| Superseded | Replaced by a later decision |
+
+Update both the record file and `DECISIONS.md` when status changes.
+
+## Intake path
+
+```text
+inbox/ or area card → triage → decisions/DEC-NNN-<slug>.md → DECISIONS.md index
+```
+
+Agents may draft decision records but must not mark `Accepted` without human
+approval per `AGENT_RULES.md`.
