{"content":"dev journal\nrepo: metaso-p2p\nbranch: codex/homepage-chats-materialized-index\ncommit: 5baf3b9\nsummary: harden homepage chats materialized index correctness before merge.\nchanges:\n1. replace steady-state homepage global serialization with layered locking: conversation-scoped lock for index assignment and alias-scoped locks for materialized homepage chat updates.\n2. change homepage index coordination to RW locking so ready-state writes hold a read lock through commit while rebuild/backfill takes the write lock and waits for in-flight writes.\n3. make corrupted homepage materialized blobs non-fatal on both read and write paths by invalidating state, continuing to persist pchat plus sender-index, and letting ensureHomepageIndexes rebuild.\n4. reduce first-run homepage materialized backfill peak memory by chunked snapshot flushing instead of retaining the full alias map until the end.\n5. add regression tests for read fallback, write fallback, conversation lock, shared alias lock, and steady-state nonblocking under homepage read lock.\nverification:\n- CGO_ENABLED=0 go test ./internal/aggregator/privatechat\n- CGO_ENABLED=0 go test ./internal/aggregator/bothomepage\n- CGO_ENABLED=0 go test ./internal/api","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
