Description
Deterministic prompt-context assembler per SPEC §14.3: ordered sections (task, comment thread, parent chain, memory, git log/diffstat) under a ~40k char budget, per-section truncate-from-tail with stable ordering so identical inputs render identical packs. Pure package + table tests first; wiring into runner PROMPT.md rendering is a separate integration step after wave 1 merges.

Depends on

  • ah-ydx — Stage 3: mem0 memory lifecycle + Context Pack parent-child open

Depended on by

  • ah-ydx.3 — Memory lifecycle: load-on-claim CONTEXT section, save-on-Done blocks

No comments.

Close reason

internal/ctxpack merged to master (342410e); format contract pinned by golden tests; runner integration tracked in ah-ydx.3
