feat(lab): completeness-floor arms for the read-scope x write-discipline 2x2

↗ view on GitHub · Eli Ziff · 2026-08-05 · d00f2f1e

Phase C cells: {whole-e2e, scoped-index} x {current prompt, +completeness
floor}. New arms mike_markdown_e2e_floor_v1 and
mike_markdown_e2e_index_floor_v1 - ONE delta vs their parent arms: the
COMPLETENESS block appended to the system prompt, verbatim from
LEAN_BATCH_LAB_SYSTEM_PROMPT (the only arm ever carrying a completeness
clause; best-ever 59/65 on covenants). Mechanism-only, no task enumeration.

Wiring: MIKE_COMPLETENESS_FLOOR flag + two prompt consts in the surface
module; chat.ts prompt ternary handles both floor cells; surface receipt
gains completeness_floor and the markdown conformance block asserts it (plus
the A1 prompt-sha gate, which covers the new prompts automatically);
armEnvironment entries, armExpectedSurface entries, singleInvocationArms,
DOCX gate, unknown-arm message, prompt_variant tags, and floor delta fields
at all three receipt sites. Both arms preflight with distinct prompt shas.
