# Window the harness may fill — deliberately BELOW the engine
# ceiling (HALOGEN_CTX=200704, lowered from 262,144 on 2026-10-17):
# the clamp below leaves the 45k gap that absorbs the estimate error.
# Both slots SHARE one 401,408-position KV pool — exactly two full
# windows — so TWO maximum-length conversations can be resident at the
# same time (at the old pool == ctx 200,704 only two of <=100k could).
# The per-request ceiling is unchanged, so this window is unchanged.
# halogenflash-server on the Strix Halo iGPU. Payload, shape, eras,
# laws, rollback: serverAppConfigs-docs/LLM/frank-dragoon.md — and
# scripts/frank-dragoon.env is the authority for every number there.
# contextWindow sits deliberately BELOW the engine ceiling
# (HALOGEN_CTX): the clamp below leaves the gap that absorbs the
# harness's chars/4 under-count, so a window equal to the ceiling
# would make every long request a guaranteed 400.

# The clamp is max_tokens = min(maxTokens, contextWindow − est −
# 4096); the chars/4 est UNDER-counts the rendered prompt by ~3 %
# on code/agent traffic (measured 2026-10-07: est 152,938 ->
# server 157,388). Worst-case request = window − 4096 + 3 % est
# error ≈ 156.2k, inside the 200,704 engine ceiling with ~44k
# margin (robust to a ~25 % under-count). Compaction fires at 85 %
# of the window = 132,300 est ≈ 136k measured — the 180k target of
# the 262,144 era is unreachable now (the window itself is 155,648)
# — and rides on frank-zealot: input ≈ threshold − keepRecent(20k)
# ≈ 112k, inside its 200,704 slot.
# error ≈ 156.2k, inside the engine ceiling with ~44k of margin

# HALOGEN_MAX_TOKENS_CAP in frank-dragoon.env must stay >= this.
