Drive-domain errors now leave the CLI as typed, machine-branchable
envelopes — a stable `type` plus `subtype` and named fields (param,
params, retryable, log_id, hint) — so scripts and AI agents can branch on
structure and act on a recovery hint instead of parsing prose.
Changes:
- Every error produced in the drive domain — validation, file I/O, and the
failures returned from its Lark API calls — is emitted as a typed errs.*
error; the exit code is derived from the error category. Drive's API calls
now go through a shared typed classifier, so failures carry subtype,
troubleshooter, a recovery hint, and the request's log_id whether the
server returns it in the response body or the x-tt-logid header; an
already-typed network/auth error is never downgraded into a generic API
error.
- Known API conditions (resource conflict, cross-tenant, cross-brand, ...)
carry a recovery hint keyed by their error class; a command can refine
that hint with command-specific guidance.
- Batch partial failures (+push / +pull / +sync, where some items succeed
and some fail) now report an honest ok:false multi-status result on
stdout — the summary and every per-item outcome stay machine-readable —
and exit non-zero, instead of a misleading ok:true success envelope.
- Duplicate rel_path conflicts report each colliding path as a structured
params entry (RFC 7807 invalid-params style).
- Static guards lock the drive path so legacy error construction — direct
envelopes or the auto-classifying API helpers — cannot be reintroduced,
making drive the template for the remaining domains.
Output changes worth noting for consumers:
- Error envelopes now carry typed type/subtype and named fields; exit
codes follow the error category (malformed or incomplete API responses
are reported as internal errors rather than generic API errors).
- Batch partial failures (+push / +pull / +sync) emit an ok:false result
envelope on stdout (summary + per-item items[]) and exit non-zero; the
per-item results stay on stdout rather than in a stderr error envelope.
Errors surfaced through shared cross-domain helpers (scope precheck, media
import upload, metadata lookup, save-path resolution) are not yet typed;
they migrate with the shared layer in a follow-up change.
