Cache writes are billed by TTL (5-minute = 1.25x input, 1-hour = 2x input) and
Claude Code writes its cache with a 1-hour TTL, but cipx_spends collapsed the
split into a single u_cache_creation lump, so AI-spend priced everything at the
5m rate (~18% cost understatement).- migration 000109: add u_cache_creation_5m / u_cache_creation_1h to cipx_spends
- CipxSpendDAO: parse and persist the split from usage.cache_creation
- CipxSpendBlockDAO: a span is a single LLM call with one TTL, so each write
block inherits the span's TTL into its tier (cache_creation_5m / _1h)

- docs(cipx): fix tierName javadoc link and migration trailing newline
Address PR #7565 review: correct the @link in CipxSpendBlockDAO to the
nested BlockRow#tierName(int, String) signature, and end migration 000109
with a trailing blank line per migrations.md.Co-Authored-By: Claude Opus 4.8 (1M context) noreply@anthropic.com
- docs(cipx): trim cost rationale from migration 000109 comment
Address PR #7565 review: keep the OSS migration comment to the technical
schema change (what the columns are and their source), dropping the
pricing/cost explanation, which lives in the cost-api repo.Co-Authored-By: Claude Opus 4.8 (1M context) noreply@anthropic.com
