Khalim Conn-Kowlessar de7fb94ff7 docs(adr): record nearby-postcode broadening (0034) + share HTTP retry primitive ... Closes out the cohort-broadening work with its decision record and consolidates the retry plumbing. ADR-0034 documents broadening the EPC-Prediction cohort to the real unit postcodes nearest the target (via postcodes.io) when its own postcode holds no same-type comparable — extending ADR-0031 decision 5. Records why postcodes.io was chosen over council[] (whole-LA, no property_type in rows), a bulk Code-Point Open / ONSPD dataset, and the OS Places radius API, and the lazy / nearest-first early-stop / soft-fail policy. Broadening-specific docstrings now cite 0034. Retry consolidation: extract the EPC client's call_with_retry into a shared infrastructure/http_retry.py keyed off a generic TransientHttpError marker, so the mechanism (exponential backoff, Retry-After) is shared while each client keeps its own transient policy. EpcRateLimitError now subclasses TransientHttpError (still an EpcApiError); PostcodesIoClient routes through the same helper, raising TransientHttpError on 429/5xx and soft-failing to the seed once exhausted (the EPC client propagates instead). Direct tests for the shared helper; EPC + postcodes.io suites repointed at the shared sleep. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-06-23 16:54:06 +00:00
