 ## 22:50 card lifetime merged; cache freed after the build; growth mapping (b) recommended
 
 `docs/analysis/card-lifetime-2026-10-05.md` (branch card-lifetime 1fecfe2) merged into ca2-coord. Decided (delegated): the GPU frees the 256 / 512 / 1,024 MiB cache after the daily dataset build (the hash never reads it; the rebuild costs 0.67 ms fill + 13.4 ms build on the 5090 at x1, about 54 ms at x4, owed); hot-table.md's resident reading is corrected, era-layout.md's freed reading stands. Recommended for the project lead: growth mapping (b), power-of-two steps at years 4, 12, 28, 60 with AND MASK, the only mapping under which the litepaper's "4 GB about four years, 8 GB more than a decade" holds (4 GB: year 4 under (b), 1.0 to 1.5 years under (a); 8 GB: year 12 or 6.3 to 7.5; 12 GB: year 28 with the cache freed; 24 GB: year 60). Public lines and the evidence row go on the integration branch (rollout plan 6c); hot-table.md line 73 (the 8 GB row counted a 5090's warps) goes to the cache agent.

The dot4 probe job is running on PC 1 (ca2-analysis tip ee42d7c carries the playbook; the 5090 confirmation is the agent's watch). PC 1 queue after it: the era six-pack job, then the hot-table added-form job. PC 2: the proving agent's, then the ca2 node suites.
