substrate(backlog): single-agent-speed → collaboration-speed trajectory + trajectory-registry concept (Aaron 2026-04-27)

[AceHack]

Summary

Files Aaron 2026-04-27 substrate-level reframe across two messages — today's substrate optimized for single-agent speed (one maintainer-agent pair); future operation needs collaboration speed (multi-agent + multi-fork) via many rounds of iterative hardening. Plus the trajectory-registry concept Aaron flagged as backlog work.

Aaron's two messages

1. "we are going to have to do many rounds of multiagent multifork hardening for our subsgtraight design, we've been really focused on single agent speed at this poing and not colloboration speed, we'll get to it and make it better over time"

2. "it probalby would help future you to know all our trajectories we have many and i forget too all we have in progress, backlog trajectory"

What's captured

• Two substrate optimization regimes (today vs future)
• Frame for evaluating substrate-design choices
• ~16 trajectories in flight as a seed list for the registry
• docs/TRAJECTORIES.md registry concept (per-trajectory: name, current/target state, status, milestones, composes-with, pointers)
• Explicit deferral: NOT blocking 0/0/0 starting point

Pull request overview

Adds a new memory entry capturing a substrate-level framing: the current factory substrate is optimized for single-agent iteration speed, while multi-agent/multi-fork “collaboration speed” requires many rounds of iterative hardening; also seeds a “trajectory registry” concept for tracking directional workstreams over time.

Changes:

• Adds a new memory/feedback_*.md capturing the single-agent-speed → collaboration-speed trajectory and a seed list of active trajectories.
• Updates memory/MEMORY.md to index the new memory entry (newest-first).

feedback_round_history_md_git_hotspot_concern_multi_fork_multi_agent_backlog_research_2026_04_27.md is referenced here as an existing related memory, but that file does not appear to exist under memory/. Either add the missing memory file, or update this reference to the correct existing filename so the cross-reference stays navigable.

Suggested change

	- `feedback_round_history_md_git_hotspot_concern_multi_fork_multi_agent_backlog_research_2026_04_27.md` — first instance of this trajectory (ROUND-HISTORY hotspot as single-agent-speed choice that breaks under collaboration-speed pressure). This memory frames it as one of many.
	- The ROUND-HISTORY hotspot concern backlog-research memory — first instance of this trajectory (ROUND-HISTORY hotspot as single-agent-speed choice that breaks under collaboration-speed pressure). This memory frames it as one of many.

This bullet points to tools/sync/, but there is currently no tools/sync/ directory in the repo (only docs/sync/). If this is intended as a future/planned tool location, consider annotating it as such (or linking to an existing doc/backlog row) to avoid it reading like a present-day path.

Suggested change

	- **Sync model**: manual paired-sync → automated 0-diff verification (`tools/sync/`).
	- **Sync model**: manual paired-sync → automated 0-diff verification (planned `tools/sync/`; current sync docs live under `docs/sync/`).

This new MEMORY.md index entry is extremely long. memory/README.md notes the index is capped at ~200 lines and entries should be kept terse; long summaries increase the chance of important newer entries being truncated out of the visible index. Suggest tightening this to a much shorter one-line summary and leaving the detail in the underlying memory file.

Sample trajectory list captured (~16 vectors) + backlog item to build comprehensive `docs/TRAJECTORIES.md` registry (Aaron + future-Otto both forget what's in flight; one-file index would help). NOT blocking 0/0/0 starting point.
