Week 06 Report

Weekly Report - Week 6 (June 29 - July 5, 2026)

I performed the following tasks during week 6:

Network-as-subcatalog architecture (completed)

Completed the network-based architecture across the harvesting and caching layers. harvester.py now exposes two separate harvest queries, one for the with-network path and one for the without-network path, so deployments that don't use the Network entity aren't forced through unnecessary grouping logic.
Implemented build_stac_catalog_with_networks along with its supporting helper functions, producing a STAC catalog structure where each network is exposed as its own subcatalog rather than everything being flattened into a single top-level catalog.
Added a dedicated per-network caching path in cache.py so network-scoped catalogs are written and invalidated independently of the base catalog.
Updated scheduler.py to call the new network-aware functions instead of the old flat harvest path.
Fixed a crash in _item_nav_links caused by hardcoded orphan-collection paths left over from before the network architecture existed, the function hadn't been updated to account for the new subcatalog structure and was producing broken navigation links for items outside any network.
With this, the network architecture itself is functionally complete. What remained was validating it end-to-end through the testing infrastructure.

Testing

Moved into setting up the testing planned for this week, which requires a reproducible local test database. This surfaced a persistent environment/schema issue in the dummy-data generation path (generator.py) that blocked verification of the completed architecture above.
Attempts so far touched the TimescaleDB/PostGIS extension setup, .env defaults, and the delete-user flow, without a confirmed fix by end of week. This is a blocker on testing, not on the architecture work itself, which stands complete.

Time away from the project

Took a personal trip from July 3-5, which further narrowed the window to resolve the testing blocker this week.

Details can be found in:

Network architecture: api/app/v1/connector/harvester.py, stac_transformer.py, cache.py, scheduler.py
In-progress fix attempts: api/app/v1/connector/generator.py, .env

What do I plan to do next week?

Continue investigating the dummy-data/testing infrastructure issue. If it remains unresolved after another push, I'll flag it to my mentors directly rather than continuing to lose time on it solo.
GSoC midterm evaluations run July 6-10 this period.

Am I blocked on anything?

The network-as-subcatalog architecture is complete and not blocked.
Testing/verification of that architecture is blocked on an unresolved dummy-data generation bug. Root cause not yet confirmed as of end of week 6.
