Phase 13 Plan 05: Upload Mechanics Slice Summary

One-liner: Provider-normalized upload conflict/retry/reauth typed mechanics with keep_both_name() helper for D-03/D-05 queue-level collision resolution.

Tasks Completed

Task	Name	Commit	Key Files
1 (RED)	Add failing upload conflict and keep-both naming tests	f47e36d	test_cloud_backends.py
1 (GREEN)	Implement keep_both_name() helper	e1ce4cb	services/cloud_operations.py
2	Add typed upload route mechanics tests	3ddf4da	test_cloud_mutations.py

What Was Built

Task 1: Provider-normalized upload contract tests + keep_both_name() helper

RED phase: Added 23 tests (16 provider behavioral + 7 keep-both naming) to test_cloud_backends.py:

TestUploadConflictSemantics:

• test_google_drive_upload_success_returns_typed_result — kind='uploaded' with provider_item_id, name, size; no credentials in result
• test_google_drive_upload_transient_error_returns_offline_kind — HTTP 503 → kind='offline' (retryable)
• test_google_drive_upload_auth_error_returns_reauth_kind — HTTP 401 → kind='reauth_required'
• test_onedrive_upload_success_returns_typed_result — resumable session success → kind='uploaded'
• test_onedrive_upload_conflict_returns_typed_conflict_kind — conflictBehavior=fail 409 → kind='conflict', reason='name_collision'
• test_onedrive_upload_never_writes_cloud_items — source scan confirms no cloud_items import
• test_webdav_upload_success_returns_typed_result — PUT success → kind='uploaded' with correct path
• test_webdav_upload_provider_error_returns_error_kind — connection timeout → kind='offline'
• test_upload_result_never_contains_credentials — parametrized over 4 providers; no access_token/refresh_token in result
• test_upload_result_kind_in_known_kinds — parametrized over 4 providers; kind must be in MUT_KINDS constant set

TestKeepBothNaming:

• test_keep_both_naming_module_exists — services.cloud_operations exposes keep_both_name
• test_keep_both_basic_pdf — Report.pdf + 1 → Report (1).pdf
• test_keep_both_counter_increments — Report.pdf + 2 → Report (2).pdf
• test_keep_both_no_extension — README + 1 → README (1)
• test_keep_both_compound_extension — archive.tar.gz + 1 → archive (1).tar.gz
• test_keep_both_preserves_existing_counter — Report (1).pdf + 2 → Report (1) (2).pdf
• test_keep_both_spaces_in_name — My Document.docx + 1 → My Document (1).docx

GREEN phase: Implemented keep_both_name(filename, counter) in services/cloud_operations.py:

def keep_both_name(filename: str, counter: int) -> str:
    """Insert collision counter before first file extension.
    
    Report.pdf + 1  →  Report (1).pdf
    archive.tar.gz + 1  →  archive (1).tar.gz
    README + 1  →  README (1)
    """

The counter is inserted before the first dot (not last), so compound extensions are preserved intact.

Task 2: Typed upload route mechanics tests

Added 7 tests to test_cloud_mutations.py verifying Task 2 behavioral contract:

1. test_upload_success_returns_typed_uploaded_body — success body has kind/provider_item_id/name/size
2. test_upload_provider_retryable_error_returns_offline_kind — offline kind from provider error, no bare 500
3. test_upload_provider_conflict_returns_conflict_kind — provider-detected conflict when cache misses
4. test_upload_reauth_result_is_typed_and_not_500 — CONN-02 token expiry surfaces as typed body
5. test_upload_queue_control_semantics_are_backend_authored — all 4 required queue fields present
6. test_upload_keep_both_name_format — service utility accessible to route layer
7. test_upload_foreign_user_blocked — IDOR protection on upload endpoint

All 7 tests pass because the upload route in operations.py (Plan 04) already implements the typed result dispatch correctly. Plan 05 adds the test coverage that was missing.

Deviations from Plan

Auto-fixed Issues

None. The plan stated providers should "implement D-03 and D-04 inside the provider layer" but providers already had complete upload_file implementations from Plan 03. Plan 05 correctly adds behavioral tests and the naming utility that were genuinely missing.

Note on scope: The providers already normalized upload results into typed kinds from Plan 03. Plan 05's contribution is:

1. Behavioral tests that prove the normalization is correct
2. The keep_both_name() service helper that the upload queue needs for conflict resolution

Known Stubs

None. The upload mechanics are fully functional. Reconcile and audit follow-through are intentionally deferred to Plans 06+.

Threat Flags

No new security surfaces introduced. Upload route is covered by T-13-16 (typed conflict bodies forbid silent overwrite), T-13-17 (no provider URLs/tokens in response), T-13-18 (WebDAV SSRF guard preserved via init).
