The conversion / link / sheet commits predate the tree cleanup, so their
comments and README/test examples still carried internal refs. Re-apply
the genericization (no internal hosts, personal names or client file ids).
- link: print Products/Files/DocEditor.aspx?fileid=… deep links (title+url)
- lib: FileEditorURL/FolderURL helpers (+tests)
- users check: verify credentials (userName vs email) via authentication.json
- projects files replace-in FOLDER_ID FILE...: hard delete same stem|ext in a
folder + fresh upload → single clean version (no version history)
- Route HTTP helpers (getJSON/formRequest/deleteReq/postJSON/putJSON/
multipart upload), Query and AuthenticateContext/ensureToken through the
deterministic 429/502/503/504 retry (retryRaw), so the integration suite
no longer fails on the shared openresty rate limit under parallel runs.
- Fix stale cmd/office/fetch integration test: loader.TaskFields was
replaced by loader.DetailForm (broke go vet -tags=integration).
- Add unit tests for Transient/DoRetry.
