Verified against the Plan 1A Rust sources:
- ItemType / ItemCore use snake_case with tag="type" internal tagging
(not the external tagging I initially wrote)
- TotpKind is default-externally-tagged (no tag attr), so it serializes
as bare "totp"/"steam" for unit variants and { hotp: { counter } }
- GeneratorRequest uses tag="kind" internal tagging
- FieldValue / TrashRetention / HistoryRetention / SymbolCharset use
adjacent tagging { tag: "kind", content: "value" }
- Fix Login form TOTP parse example and "gen" button payload
No scope change — this is a bookkeeping correction so the plan
author references the correct wire shapes.

Foundation slice of the browser-extension migration onto the typed-item
core from Plans 1A+1B. Scope: WASM artifact rebuild, typed-item shared
types, SessionHandle-based service worker, split router with sender
checks, full security architecture (origin-bound autofill, TOFU ack,
closed Shadow DOM, popup captured-tab verification), zxcvbn setup gate,
Login-parity popup. Other 6 item types land in 1C-β; attachments/trash/
history/device UI in 1C-γ.
