archive_run_items.produced_entry_id has no ON DELETE action so it must
be manually nulled before the entry row is deleted. The old query used
WHERE root_entry_id = entry_id, which finds descendants of a root but
returns nothing when entry_id IS a child (children have no sub-children,
so no row has root_entry_id = child_id). The DELETE then failed under
foreign_keys=ON.
Fix: add OR produced_entry_id = ?1 so the entry's own run_item FK is
always cleared before deletion, regardless of whether it is a root or a
child. The subtree subquery is kept for the root-deletion case where all
child run_items also need nulling.
AGENTS.md: mention Freedium mirror in the overview and capture flow,
add vendor/readability/ to Key Directories, drop the NEXT.md pointer.
ARCHIVR-MENTAL-MODEL.md: fix stale references to legacy static/ paths
in Where To Edit (frontend now lives in frontend/src/); add capture.rs
and auth.rs rows; replace the outdated 'Current Limitations' section
(which claimed no capture and no auth) with a Server Capabilities
section reflecting async capture jobs, the auth model, search, and
admin scope; add a Web Capture Pipeline section covering the Freedium
mirror, SingleFile+Chromium, vendored Readability, cleanup, and Rust
post-processing.
NEXT.md: remove; the roadmap tracking is stale and unused.
