A caret Backspace or Delete replaces no selection, so `beforeinput` reports
the bare caret and the previous derivation produced a negative inserted
length and fell back to the ambiguous scan. The delete half of the defect
survived, and the component test missed it by pre-expanding the selection to
the span the engines never report.
The range for a caret delete now comes from the direction `inputType` names
and the number of characters the draft actually lost, measured rather than
assumed to be one, so a grapheme, word, or line deletion sizes correctly.
Only the insert and delete families are recorded; a history replay reports
wherever the caret sits and would name a wrong span while passing every check.
Component tests cover the caret Backspace, Delete, and word-delete gestures,
and an assembled browser scenario drives them as real key presses, which is
the only place an engine's reported range is observable.
Replace the legacy reference.* API Proxy domain with @Remote methods on the
owning services, following the typert gateway design master adopted on
2026-08-02 (message-feedback and plugin-inventory precedents):
- FileReferenceService and SessionReferenceResolver extend TypertRemoteService;
fileReferences/list and sessionReferenceResolver/candidates are unary Remote
methods cancelled through the reserved trailing signal, and the candidates
face attaches each candidate's canonical mention under the configured limit
- move the wire types to type-only ./types subpaths (FileReferenceCandidate,
SessionReferenceMentionCandidate) and export ./typert plus ./remote artifacts
- mount both contributions in the api-remotes client assembly; ui-reference
consumes ctx.remote instead of connection.api.references and registers zh/en
locale dictionaries for its sections and labels
- delete the reference.* routes, schemas, map rows, client stubs, and fixtures;
the connection fixture serves the Remote endpoints instead
- release deliverPrompt admission listeners when the agent is disposed with the
prepared prompt still pending, and cover the reference-* RpcError codes in
the schema spec
- add the missing tsconfig paths for the /grammar and /types subpaths (clean-
tree vitest could not resolve @deepseek-ai/dsh-file-reference/grammar)
- regenerate the cordis catalog, capability seams, and event matrix; update the
owning bilingual READMEs, Agent Notes, and the reference-composer golden
