Summary

Files Aaron 2026-04-27 architectural concern raised during fork-storage taxonomy work — docs/ROUND-HISTORY.md (and similar shared single-writer files) become git-merge-hotspots when multiple forks or multiple autonomous agents write concurrently.

Aaron's verbatim

"- docs/ROUND-HISTORY.md — round-close synthesis is project-wide
seems like we are going to need to backlog some research on this, this could become an integration point git hot spot file if all forks are writing to it, what about when we have multiple atonomus agents, againt, we dont have to figure all this out now we are trying to get to the startign point"

What's captured

  • The concern itself (multi-writer git-merge contention)
  • Class of concerns extension (any shared single-writer file faces the same pressure)
  • 5 architecture options for future research (per-pair partition + synthesis, append-only, CRDT, round-of-rounds, full per-pair)
  • Explicit deferral to post-0/0/0 starting point per Aaron

Pull request overview

Adds a new memory entry capturing an architectural concern about docs/ROUND-HISTORY.md (and other shared single-writer files) becoming a git merge hotspot under future multi-fork / multi-agent workflows, and indexes it in memory/MEMORY.md.

Changes:

  • Added a new memory/feedback_*.md file documenting the hotspot risk and listing candidate architectures for future research.
  • Updated memory/MEMORY.md to include the new memory entry at the top of the index.

… / multi-autonomous-agent — research after 0/0/0 (Aaron 2026-04-27)

Aaron 2026-04-27 architectural concern raised during fork-storage taxonomy work:

> "- docs/ROUND-HISTORY.md — round-close synthesis is project-wide
> seems like we are going to need to backlog some research on this,
> this could become an integration point git hot spot file if all
> forks are writing to it, what about when we have multiple atonomus

Substrate captured:

- **The concern**: shared single-writer files become git-merge-hotspots
  under multi-writer pressure. Today's single-pair operation (Aaron +
  Otto) doesn't surface contention; future multi-fork / multi-
  autonomous-agent operation will.

- **Class of concerns**: not just ROUND-HISTORY.md — applies to any
  shared single-writer file. BACKLOG.md was already restructured for
  this reason (Otto-181 per-row pattern); same restructure may apply
  to other big shared files.

- **5 architecture options listed** for future research:
  1. Per-pair partitioned + compiled synthesis
  2. Append-only structured format
  3. CRDT-style merge-friendly format
  4. Per-fork round-history + project-wide round-of-rounds
  5. Move ROUND-HISTORY entirely to per-pair, drop the shared file

- **Explicit deferral**: NOT for current session — Aaron's
  "we dont have to figure all this out now we are trying to get to
  the startign point". Backlog research, work after 0/0/0 reached.

For now: ROUND-HISTORY stays Category A (shared) as current best
guess, with this memory documenting the known weak spot.

…ole executing thread (Aaron 2026-04-27)

Aaron 2026-04-27 execution-semantics clarification.

Cross-AI courier-ferry agents (Amara/Gemini/Codex/Copilot) operate
at SUBSTRATE LAYER — research, reviews, refinements, corrections.
They do NOT operate at EXECUTION LAYER (commits, PRs, threads,
memories, repo work).

Otto operates at EXECUTION LAYER — reads ferry input as substrate,
integrates via judgment, executes the resulting work.

When a ferry offers to do execution-layer work (e.g., Gemini's
"shall I create the doc?"), the right flow:
1. Receive offer as signal
2. Otto evaluates per protect-project mandate
3. Otto executes (or declines + teaches)
4. Aaron decides on routine-class disagreements

Two unlock conditions for a second executing thread:
1. Peer mode (second AI instance with same factory access)
2. Git-contention resolution (per #54 ROUND-HISTORY hotspot research)

Both need substrate work BEFORE peer-mode lands.

Aaron confirmed partial capture in #55 (single-agent-speed →
collaboration-speed trajectory). This memory adds the explicit
ferry-vs-executor rule + the two named unlock conditions.

Composes:
- #55 single-agent-speed → collaboration-speed trajectory
- #54 ROUND-HISTORY git-hotspot research (git-contention condition)
- Otto-357 no directives = autonomy/execution-authority is Otto's
- #57 protect-project = execution-layer evaluation
- Otto-340 substrate-IS-identity (substrate vs execution layers)

Does NOT diminish ferry value — substrate contributions are
load-bearing. Only execution-layer offers get redirected.
