Superseded by #2560 (clean folder-expand feature via /files/:file_key/folder with XML output + unit tests).

…hint

When message content contains a folder (messages-mget / chat-messages-list / threads-messages-list), folderConverter now calls GET /open-apis/im/v1/resources/:file_key/children (srctype=message&srcid=msgid&recursive=false) to expand one level, outputting first-level files/subfolders with children_count hint for deeper levels (recursive=true to expand fully). Falls back to legacy <folder key name/> output when Runtime/MessageID missing or API unavailable.

📝 Walkthrough

Walkthrough

The folder converter now fetches one level of folder children and emits tree-shaped XML. Feishu requests use BOE headers and hosts. Tests cover expansion, pagination, API failure, and empty results.

Changes

Folder expansion

Layer / File(s) Summary
BOE request routing
internal/cmdutil/transport.go
SecurityHeaderTransport.RoundTrip adds x-tt-env: boe_folder, rewrites Feishu hosts to BOE hosts, and logs request details.
Folder tree conversion
shortcuts/im/convert_lib/misc.go
folderConverter.Convert fetches non-recursive folder children when runtime data is available. The helper builds XML entries with child_count and has_more, and preserves flat XML on fallback.
Folder tree validation
shortcuts/im/convert_lib/folder_test.go
Tests cover one-level XML expansion, pagination attributes, API failure, and empty results.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to cccc8

This PR changes shared request handling so production API and account traffic can be redirected to a BOE environment while full request headers, including credentials, are printed. Unrelated operations could be misrouted or expose sensitive tokens, so it is not merge-ready until the debug routing is removed or explicitly gated and header logging is safely redacted.

- Around line 173-188: Gate the BOE routing and x-tt-env header logic in the
transport function behind an explicit debug-only configuration, preserving
unchanged production routing and headers by default; update both URL and
req.Host rewrites only when opted in, and add regression coverage for default
production behavior and explicit BOE opt-in.
- Around line 189-192: Remove the unredacted request-header loop in
SecurityHeaderTransport so Authorization and other sensitive values are never
written to os.Stderr; if header tracing is required, restrict it to an explicit
allowlist of non-sensitive fields while preserving the existing request debug
context.

folder expansion and flat-folder fallback when runtime context is unavailable or

fetchFolderChildrenTree, and ensure the tests fail if that branch is reverted.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Expand regression coverage for folder expansion.

Assert that the folder-children request sends srctype=message, the expected srcid, and recursive=false. Also add converter-level tests covering successful expansion and flat-folder fallback when runtime context is unavailable or the API call fails, so reverting the changed conversion branch makes the tests fail.

Project the folder-children response into typed structs.

DoAPIJSONTyped returns map[string]any, and this function silently ignores failed assertions for items and item fields. A malformed response can become an empty result or XML elements with empty attributes. Define local typed response and item structs at this boundary.
