…nding queue; trim patch

Filed four upstream PRs on 2026-04-30:
- rboarescu#15  feat: GET /viz status dashboard (stacks on rboarescu#13)
- rboarescu#16  feat: GET /list — query-free metadata browse
- rboarescu#17  feat: DELETE /memory + PATCH /memory
- rboarescu#18  feat(lifespan): auto-migrate Stop-hook checkpoints on startup

Also rebased PR rboarescu#13 onto upstream/main to clear a CHANGELOG conflict
left by upstream's b4aee82 (patch sync) — state went CONFLICTING ->
MERGEABLE / CLEAN.

README:
- Open upstream PRs table: four new rows (rboarescu#15-rboarescu#18) plus a 2026-04-30
  note covering today's rebase + new PRs in one breath.
- Pending PRs queue: now empty. Replaced the four stale rows
  (event-log-frame and graph-endpoint were already in flight via
  rboarescu#11 and rboarescu#13; mempal-fast.py was already upstream via the merged
  PR #4 omnibus; /viz is now PR rboarescu#15) with a brief empty-state note.

CLAUDE.md:
- Patch description trimmed to reflect that the hnsw:num_threads
  enforcement landed upstream via _pin_hnsw_threads(); only the
  log + retry-once slice remains.

patches/mcp_server_get_collection.patch:
- Regenerated against current mempalace develop. The patch is now
  just the "log exception + retry once on cache failure" change.
  Filed upstream as MemPalace/mempalace#1286; once that merges this
  patch retires.

README:
- Intro paragraph: appended GET /list (PR rboarescu#16), DELETE/PATCH /memory
  (PR rboarescu#17), and lifespan auto-migrate (PR rboarescu#18) to "what this fork
  adds" since they're already on fork main even though the PRs are
  awaiting review upstream.
- Links bar: added docs/typescript-port-plan.md.
- Added a "Cross-repo coordination" subsection under "Recently landed
  in upstream" — calls out the local patches/ directory and the
  in-flight MemPalace/mempalace#1286 that retires it. Also references
  #1142 (RELEASING.md) for completeness.
- Requirements: dropped the stale "kind= searcher filter" justification
  for recommending the fork (kind= was retired in 1.7.1); replaced
  with daemon-strict hook mode + warnings/sqlite-fallback search path
  as the actual current reasons. Added the patches/ re-apply step.
- API table: added /list, DELETE /memory/{id}, PATCH /memory/{id}
  rows so the table reflects what the fork main actually exposes.
- Sources: cross-repo PR note for #1286.

CHANGELOG:
- Added [Unreleased] section: patch trim (Maintenance), TS port plan
  doc, hook-routing-fix.md status header, and a Docs entry covering
  today's README updates + PR rboarescu#13 rebase context.

docs/hook-routing-fix.md:
- Added a Status: SHIPPED header pointing at 62425e3 (2026-04-24
  clients/hook.py introduction) and clarifying mempal-fast.py is the
  simpler successor — same shape as docs/graph-endpoint.md's status
  header.

No daemon behaviour changes.

…boarescu#18 + #1286 to main

Same shape as 152e428 — production at disks runs fork main, so review
amendments to the in-flight upstream PRs need to ship here too.

## main.py — /list docstring (from PR rboarescu#16)

The previous docstring claimed both "sorted by recency" and "ordered
by mempalace's natural metadata-table order", which contradicted
itself. Replaced with an accurate description: ordering is whatever
mempalace_list_drawers returns (sqlite metadata-table order, which
approximates insertion order but isn't strictly chronological).
Pagination contract called out explicitly.

## main.py — PATCH /memory body validation (from PR rboarescu#17)

- await request.json() now wraps in try/except for JSONDecodeError →
  400 with a clear message (was bubbling as 500).
- Validate parsed body is a dict before reading keys.
- Reject empty patches (no content/wing/room) with 400 listing the
  valid keys, instead of forwarding {drawer_id: ...} alone to
  mempalace_update_drawer where it's an ambiguous no-op.

DELETE handler unchanged — no body parsing, nothing to harden.

## main.py — Lifespan auto-migrate ImportError narrowing (from PR rboarescu#18)

Previous `except ImportError:` swallowed transitive dep failures
inside mempalace.migrate (a real bug worth surfacing) as if they
were "feature unavailable" (expected). Distinguish via
`getattr(e, "name", None) == "mempalace.migrate"` — module genuinely
absent → debug log, anything else → warning log so it's visible.

Comment that pointed at `mempalace docs/superpowers/specs/2026-04-25-
checkpoint-collection-split.md` (a path that doesn't exist in this
repo, lives only in the jphein/mempalace fork's superpowers tree)
replaced with a public-facing reference to `mempalace repair --mode
reorganize` — the operator-driven equivalent that's actually
discoverable.

## patches/mcp_server_get_collection.patch (from MemPalace/mempalace #1286)

Regenerated against current upstream develop with the Copilot review
fix folded in: logger.error(..., str(e)) → logger.exception(...).
Now the traceback lands in the daemon log alongside the message
instead of being dropped. Patch behaviour is otherwise identical.

The upstream PR also gained TestGetCollectionRetry — three monkeypatch
tests that pin the retry semantics. Those tests live in mempalace, not
here; they'll arrive on this side automatically once #1286 merges and
the patch retires.

All four fixes are amendments on the corresponding upstream PR
branches (force-pushed earlier today). No behaviour change for the
healthy path; the changes harden failure modes that were caught in
review.
