{"content":"Development journal for commit 47be76a5 (feat: MetaTask P0 — port replay engine core (both modes) with full engine/competitive test suites).\n\nPorted the MetaTask replay engine verbatim from IDBots into src/core/metatask/engine/ (types, constants incl. H_ACT=190000/H_ACT2=191500/H_ACT3=192800, canonJ+double-hash, engine with tree+competitive modes, mid-task estimation, deadline clocks). Compiles clean under OAC strict tsconfig; engine+competitive suites (64 cases, IDBots 43+25 minus the 5 collector-only tests that move with the P1 collector port; the roster test now feeds rosterPins directly) pass 64/64 under Node 24, including the frozen v1.2 Appendix A hash calibration vectors — byte-level canon fidelity confirmed. engineAlgoVersion strings and PROJECTION_FORMAT_VERSION=3 kept untouched for the P2 conformance digest.\n\nVerification:\npnpm run build && node --test --test-concurrency=1 tests/metatask/engine.test.mjs tests/metatask/competitive.test.mjs\n\nFiles:\nsrc/core/metatask/engine/canon.ts\nsrc/core/metatask/engine/constants.ts\nsrc/core/metatask/engine/deadlines.ts\nsrc/core/metatask/engine/engine.ts\nsrc/core/metatask/engine/estimate.ts\nsrc/core/metatask/engine/types.ts\ntests/metatask/competitive.test.mjs\ntests/metatask/engine.test.mjs","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
