Adding a published Python backend and reordering `flush_line` left several owning documents stating things that are no longer true. `src/invariant.ts` justified its empty installer with "ships only the fd-3 wire-protocol codec", which the subprocess execution path contradicts. The reason now states the actual one: every relation this backend maintains lives in the CPython child or on the fd-3 wire, so no same-process event sequence is observable from a listener -- the same shape the sibling worker-thread backend uses. The seam's `PORTABLE_RESERVED_WORDS` and `language` JSDoc, the code-runtime README pair, and docs/subsystems/code-runtime both said only TypeScript has a published backend. Corrected in all four, with the generated cordis catalog regenerated for the `language` change. The note attributed the 12x multiple to the settlement flush holding three copies. That stopped being true when `flush_line` was reordered to drop the pending chunks before its push: the binding worst case is the newline path's single near-budget write. Corrected in the note (both sides) and in the test comment that repeated it. The note's Testing section now registers the cases this stack added, and the Chinese side receives the O(depth) entry it never got plus the new ones -- it had drifted from the English. `INTERPRETER_BASELINE_BYTES` argued 64 MiB from a RESIDENT set while RLIMIT_AS bounds address space. It now cites the bootstrap's own measurement (30.23 MiB of mappings for `python3 -I`), making 64 MiB roughly twice the measured baseline. Also: a hardcoded `(:232-235)` comment reference becomes a reference by name, a "which now walks in O(depth) too" change narrative becomes a current-state statement, and a stray double blank line is removed.
Subsystems
English | 中文
One page per subsystem of the DeepSeek Harness: what it is, the data structures it moves, and — where a ctx service or event scope backs it — a generated Cordis API section carrying its service and event reference. The folder complements architecture.md, which describes behavior across subsystems (the service map, the session/turn/step lifecycle, the event taxonomy); each page here is the reference for one subsystem's vocabulary and wiring.

Type declarations and their JSDoc on these pages are source-equivalent and drift-checked by
pnpm run verify-type-equiv(see development.md). Ordinary blocks preserve complete declarations;public-apiblocks preserve body-stripped public class declarations. Cordis services and events use each page's generated Cordis API section.
