Restore is a database re-point — `stored_relpath` is projects-root-relative, so no file ever moves (spec §10.6) — inside one transaction that locks the target active project row, then the source and any merge-candidate rows in ID order; identical active bytes in the target merge (trash row deleted, discarded namespace unlinked best-effort after commit), and a read-only existence/size check under the document lock rejects restores of missing or size-mismatched content with `409 content_missing`, leaving the row trashed. Purge holds the document-row lock continuously across trashed-state revalidation, unlink of the original and `derived/converted.md`, row deletion, and commit: already-absent content counts as removed, any other unlink error rolls back and keeps the row retryable, and retention callers revalidate the selected trash timestamp and cutoff under the lock so a restored-and-re-trashed row is never purged on its former expiry. Empty trash (`POST /api/trash/purge`) runs that same guarded purge once per trashed row of the caller with no age filter — the confirmation covers the whole listing — so the retention cutoff gates only the sweep's candidate selection. The retention sweep runs lazily on `GET /api/trash/documents` and once at gateway startup (no daemon): it purges rows at or past `projects.trash_retention_days` through the same guarded path, then reconciles storage — `.staging/*` entries and unreferenced files older than 24 hours are removed (nothing younger is ever collected; any active or trashed row protects its whole namespace, even after restore to another project) — and detects rows with missing or size-mismatched content, logging them at warning and surfacing them as `content_missing` without ever deleting the row (the row is the user's only record; disposal always starts with the user trashing it). +**Document summaries (opt-in).** `project_documents.summary` is a nullable, best-effort LLM one-liner. The two shelf write routes enqueue a job after row creation (`projects/summaries.py`, off unless `projects.summaries_enabled`); a bounded worker pool (`summary_concurrency` + bounded `summary_queue_size`, full queue drops) resolves text through `read_text_serving_path` (never re-deriving the convertible-first rule), calls the model via `run_oneshot_llm` with a caller-side wait limit (the worker slot is held until the provider call actually finishes; late results are discarded), rejects length-capped output through the shared provider-normalized detectors, and applies a write-time contract (unwrap → single line → empty is NULL → byte cap on a character boundary) before persisting with `updated_at` pinned so a landing summary never reorders the shelf. The summary rides the row's lifecycle (trash/restore/purge need no hooks), renders into the `` index and `list_project_documents` tag-neutralized at both exits, and is counted through `eligible/success/failed/skipped/queue_dropped/uncapped_accepted` metrics.
