I found the relevant packet under `.opencode/specs/system-spec-kit/026-graph-and-context-optimization/003-continuity-memory-runtime/004-memory-save-rewrite`. I’m pulling the decision-bearing docs and anchor names now.

I’ve got the main decision and the fallback/reserved behavior; I’m checking the exact anchor coverage so I cite packet-local anchors rather than just line ranges.

**Decision found:** in `026/003/004`, `SPECKIT_SAVE_PLANNER_MODE` was decided as **planner-first by default**, with **`full-auto` kept as an explicit fallback** and **`hybrid` kept reserved, currently behaving like `plan-only`**.

| Decision | Rationale | Source anchor |
|---|---|---|
| Default mode is planner-first / non-mutating | Research concluded the save path already had enough route, legality, and follow-up information to return a plan without mutating. That made the default path reviewable, reduced hot-path cost, and removed dependence on optional subsystems. | `decision-record.md#adr-001` *(ADR-002 lives inside this anchored ADR ledger)*, `implementation-summary.md#what-built` |
| `full-auto` remains available only as explicit fallback | The canonical atomic writer was still considered load-bearing and worth preserving for cases that truly need automatic mutation, safety parity, rollback, and same-path identity. | `decision-record.md#adr-001` *(ADR-002 in ledger)*, `spec.md#scope`, `implementation-summary.md#decisions` |
| `hybrid` is reserved and currently behaves like `plan-only` | The packet explicitly chose documentation honesty over implying mixed behavior that does not yet exist, so operators do not assume unsupported semantics. | `spec.md#scope`, `spec.md#requirements`, `implementation-summary.md#limitations` |

**Most direct rationale text:** “Make planner-first output the default `/memory:save` contract and preserve `full-auto` as explicit fallback,” because keeping `full-auto` as default would preserve “unnecessary hot-path cost,” while planner-first makes the default path “reviewable and non-mutating.” Source: `decision-record.md#adr-001` *(ADR-002 section within that anchor)*.
