Captures the full RLM-fundamental story across the design doc, MODES.md,
and the Hetun prompt. Tracking issues are now #46–#55 (helper layer
filed as #53, Hetun as #54, vendoring as #55).
What this nails down:
- **Hetun mode** is added at the END of the Tab cycle (Plan → Agent →
YOLO → Hetun → Plan), not as a Plan replacement. Default landing mode
is unchanged so people don't accidentally start there. Plan stays as
it is.
- **Mission-level approval, not block-level.** Hetun runs a research
phase, presents one mission card, and only executes after explicit
user approval. Inside the execution turn the repl block runs straight
through with no per-block prompts — that's the whole point of the
mode.
- **The user's configured model is left alone on enter/exit.** Pro/max
users stay on Pro/max. The flash-as-coordinator behaviour is internal
to the runtime (ZIGRLM_RLM_CMD always points to flash regardless of
mode). No global model swap.
- **No /hetun slash command.** Tab cycles into the mode; /plan keeps
switching to Plan as today.
- **The helper layer (#53) is fundamental, not aleph-derived.** A
curated ~20-function ctx-helper module + AST-validated Python sandbox
baked into the repl runtime so a single block can load → slice → fan
out flash queries → aggregate without crossing tool boundaries.
Inspired by aleph's pattern but our own native primitive — not a port.
- **Hetun research methodology adopts Sakana's Fugu patterns.** The
research phase is recursive novelty sampling + hierarchical narrative
tree synthesis + multi-detector cross-verification (flash for
breadth, Pro for depth) + hypothesis-verification loop. Not "fan out
8 fixed queries". This is what makes "Plan + Recursive Agents"
meaningful versus a flash-coordinator wrapper.
- **No version-number framing anywhere.** The plan ships as one cohesive
RLM landing across #46/#48/#49/#50/#53/#54/#55 — order is dependency,
not release schedule. We keep shipping.
- **Auto-compaction stays automatic.** Removed a manual /compact nag
from the Hetun prompt; the existing coherence + capacity system
already handles this.
