Phase 0 implementation per PHASE0.md §6, §8.
Context.new(opts) constructs with the §6 default system prompt (the
`CMD: ` extraction contract is hard-coded in there per §3 — locked
substrate, do not edit). opts overrides: system_prompt, max_turns
(default 40), token_budget (default 4096; visibility only in Phase 0
per Q1, deferred to Phase 3 for accurate tokenization).
API:
ctx:append({role, content}) record a turn
ctx:to_messages() [{system,...}, ...turns] for broker.chat
ctx:enforce_budget() evict pairs (user+assistant) until
#turns <= max_turns; returns count
ctx:estimate_tokens() char/4 heuristic
ctx:reset() drop all turns (system_prompt kept)
System prompt is the §6 phrasing verbatim including the `CMD: ` clause
— stored on the context, NOT in self.turns, so it is prepended freshly
on every to_messages() call.
Smoke covers basic ops, no-evict-at-max, evict-on-overflow, bulk
eviction (14 turns -> 4), reset.

- README, .gitignore, CLAUDE.md (project conventions)
- docs/PHASE0.md — full Phase 0 manifest (locked substrate)
- 10 root .lua modules + 4 ffi/ bindings, all stubs raising NotImplemented
with module-scoped responsibilities matching the manifest
- config.lua wired to current dirac/hossenfelder endpoints (qwen-coder-7b
snappy/32k + cloud via OpenRouter through hossenfelder)
File names match docs/PHASE0.md §4 exactly. Module bodies fill in across
later phases; the tree shape is locked.
