Moderate activity across normalize, crescent, io, and mycelium. Focus on architecture and infrastructure refinement.

Sessions and Activity

normalize

Session bed1324e — VCS abstraction design and scoping.

• Checked recent TODO.md additions (grammar versioning, git stash triage, C/C++ header fixes).
• Explored version-control abstraction roadmap (VCS trait, sessions blame feature).
• Scoped VCS abstraction crate design: settled on normalize-vcs with Vcs trait, domain types (CommitId, BlameLine), and GitBackend wrapper.
• Discussed sessions-blame matching algorithm (content-aware, file-path-aware, change-granularity).

crescent, io

Light exploratory work ongoing from prior days.

mycelium

Session 5efec56b — Runtime architecture continuation from prior work.

Token Usage

Project	Sessions	Output Tokens
normalize	1	~8,000+
crescent, io	2+	~2,000
mycelium	1	~1,500

Total: ~11,500 output tokens.

Observations

1. VCS abstraction trajectory clarified. Normalize settled on a normalize-vcs crate with domain-type boundary; full migration from normalize-git deferred to next phase.
2. Sessions blame scoping complete. Matching algorithm designed: content-aware, file-path-aware, change-granular — no timestamp-proximity heuristics (reliability > recall).
3. Architecture-level decisions made. Decisions on trait placement and domain types will shape next sessions' migration work.

Projects Touched

• normalize — VCS abstraction design.
• crescent — light continuation.
• io — light continuation.
• mycelium — runtime work.
