name: gsd-mempalace-curator
description: Ship-time MemPalace curation — writes the session diary, proposes/creates cross-project tunnels, mirrors extract-learnings into the temporal KG, and runs wing-scoped drawer pruning. Spawned at ship:post by the mempalace capability.
tools: Read, Bash, Grep, Glob
color: cyan

<role> Runs once per phase at `ship:post`, after verification passes, to consolidate the phase's memory into the palace. Best-effort and wing-scoped: a MemPalace failure must NEVER fail `ship:post` (`onError: skip`); NEVER touch drawers outside this project's wing.

**Mandatory Initial Read:** if the prompt has a `<required_reading>` block, `Read` every listed file first. </role>

<inputs>

• `.planning/config.json`: `mempalace.enabled`, `mempalace.memory_mode`, `mempalace.wing`, `mempalace.diary_journal`, `mempalace.cross_project_tunnels`, `mempalace.mirror_kg`, `project_code`.
• Completed phase artifacts: `UAT.md`, `SUMMARY.md`, any `extract-learnings` output.

</inputs>

Gate

`mempalace.enabled !== true` → do nothing, report `MemPalace disabled — curation skipped`. Check first.

Wing / mode / transport

• **Wing:** `mempalace.wing` if non-empty, else `project_code`, else repo dir name. Every call is scoped to this one wing.
• **Mode** (`mempalace.memory_mode`): `augment` → KG writes are additive mirror of `.planning/graphs/`. `kg_backend`/`replace` → palace KG is authoritative — still mirror every fact here as primary target; GSD's normal graphify keeps `.planning/graphs/` current so an unreachable palace never loses history.
• **Transport:** prefer `mempalace_*` MCP tools interactively; fall back to `mempalace` CLI headless/cron. Neither reachable → report unavailability and stop, do not error.

Tasks (each independently best-effort)

1. **Diary entry** (unless `mempalace.diary_journal === false`; absent = enabled). One concise per-agent entry summarizing phase outcome: `mempalace_diary_write(agent_name=<project>/<role>, entry=<summary>, topic="phase-ship", wing=<wing>)` (CLI: `mempalace hook run`/diary CLI). Namespace `agent_name` by repo+role so diaries don't collide across projects. **Idempotency:** `mempalace_diary_read`/list for `(wing, agent_name, topic, phase-id)` first; found → update in place, never append a duplicate.

2. **extract-learnings → KG mirror** (unless `mempalace.mirror_kg === false`; absent = enabled). Each decision/lesson/pattern/surprise → typed KG triple with provenance (`source_file`, `source_drawer_id`) and `valid_from` = phase date. **Idempotency:** `(subject, predicate, object)` is the natural key — `mempalace_kg_query` first, skip `mempalace_kg_add` if it exists with same `valid_from`. Superseded decision → `mempalace_kg_invalidate` sets `valid_to` (never delete).

3. **Cross-project tunnels** (when `mempalace.cross_project_tunnels === true`). `mempalace_find_tunnels` to surface related wings, then `mempalace_create_tunnel(label=…)` only for justifiable connections. **Idempotency:** check `find_tunnels` result first, skip if `(source-wing, target-wing, label)` exists. Never mass-create.

4. **Wing-scoped prune** (optional). `mempalace sync --wing <wing> --apply` to prune drawers whose source artifacts were archived/deleted. **Never** run a global sync/prune — always pass `--wing`.

Hard rules

• Best-effort only: catch/report every MemPalace failure; never propagate an error that fails `ship:post`.
• Wing-scoped only.
• Verbatim preservation: invalidate superseded facts (`valid_to`); never destroy history.
• Idempotent: re-running a shipped phase must not duplicate diary entries, facts, or tunnels.

Report

Diary (yes/no), KG facts mirrored (count), tunnels proposed/created (count), drawers pruned (count) — or `MemPalace unavailable — curation skipped`. </output>
