file_info.py DOX

Purpose

Own the file_info.py API endpoint.
This module handles file info API requests.
Keep this file-level DOX profile synchronized with file_info.py because this directory is intentionally flat.

file_info.py owns the runtime implementation.
file_info.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
Classes:
FileInfoApi (ApiHandler)
- async process(self, input: Input, request: Request) -> Output
FileInfo (TypedDict)
Top-level functions:
async get_file_info(path: str) -> FileInfo

HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
FileInfoApi is an ApiHandler.
FileInfoApi defines process(...).
Observed side-effect areas: filesystem reads.
Imported dependency areas include: helpers, helpers.api, os, typing.

Important called helpers/classes observed in the source: files.get_abs_path, os.path.exists, os.path.dirname, os.path.basename, runtime.call_development_function, os.path.isdir, os.path.isfile, os.path.islink, os.path.getsize, os.path.getmtime, os.path.getctime, os.path.splitext, os.stat.
Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
Update frontend callers, plugin callers, and tests together when payload shape changes.
Use helpers.api.Response for non-JSON responses, files, redirects, or status-specific replies.

Run endpoint-specific or API/WebSocket tests for changed behavior; smoke-test browser callers when no focused test exists.
No direct test reference was found by name search; choose the nearest behavioral test or perform a focused smoke check.

No child DOX files.
