Fixes #1812

Description

---

This PR has:

• been tested to ensure log ingestion and log query works.
• added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader.
• added documentation for new or modified features or behaviors.

Summary by CodeRabbit

• Bug Fixes
  • Corrected retention cleanup paths for non-default tenants, helping ensure the intended tenant’s data is targeted. Default-tenant and tenant-unspecified paths remain unchanged.

Walkthrough

Retention deletion paths now include the tenant ID for non-default tenants. The default tenant and missing tenant IDs retain the stream-and-date path format. The tenant ID continues to be passed separately to delete_prefix.

Changes

Retention deletion

Layer / File(s)	Summary
Tenant-aware deletion path src/storage/retention.rs	The action module imports DEFAULT_TENANT. Deletion paths include the tenant ID for non-default tenants; default or missing tenant IDs use an empty tenant component.

Change: Bug fix

Merge Risk: High · up to 4be72

Retention for non-default tenants on GCS and Azure Blob will silently delete nothing, because date listing still looks under the stream-only prefix. Fix the backend date listing before merging.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Description check

Explanation

The description includes the linked issue, but the required Description section is empty and the checklist does not confirm testing, comments, or documentation. It does not explain the tenant-aware retention path change or its rationale.

Resolution

Add a concise description of the goal, chosen solution, rationale, and key code changes. Update the checklist to reflect whether log ingestion and querying were tested, explanatory comments were added, and documentation was updated. Remove or mark any item that is not applicable.

For each tenant, it gets them right
The default stream keeps its old trail
No tenant? The date paths prevail
The delete call gets its tenant too
Then hops away beneath the moonlit blue}

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Use tenant-aware prefixes in GCS and Azure date discovery.

For a non-default tenant, uploads use tenant/stream/..., but both _list_dates implementations list only stream/. Retention can therefore find no dates and skip deletion. Apply the fix in the backend implementations, not in src/storage/retention.rs. Do not change LocalFS because it is single-tenant.

Apply the same prefix and stripping logic in src/storage/azure_blob.rs.
