Forward-planning survey (not v0.8.1 scope). Two independent sweeps (PM 3-agent +
Dev-D 4-reader workflow with adversarial critic), reconciled and hand-verified
against source at b09e0ce. Headline: core item-CRUD at full parity (extension
often ahead); genuine extension gaps cluster in metadata management (group/tag/
filter editing limited to specific forms, zero favorites UI), backend-exists-no-
wire items (remove_attachment, per-item purge, isInTab attachment gate), autofill
hostname matching, and the org vault (largest, already specced/deferred).
