Break the stage+commit window into sub-phases (FAT working-tree walk vs object writes) via `commit split —` log lines, and add two micro-benchmarks (sd_bench for SD/FAT primitive ops, git_bench for libgit2 object overhead) with justfile recipes. Documents the walk-vs-writes cost model in tradeoff-curves/sync-commit-staging.md to decide whether explicit-path staging over the editor's dirty set is worth replacing add_all(["*"]).
Notes
Longer-form essays on the thinking behind specific Typoena choices — the arguments too big for an ADR and too durable for a commit message.

| Note | What it argues |
|---|---|
ctrl-g-perceived-latency.md |
Durability before delivery — surfacing "commit landed" at ~0.2 s makes the 5–10 s Ctrl-G push feel instant. |
git-sync-images-and-repo-size.md |
Why we don't shrink the notes repo — its 153 MB of media is remanso's image CDN, so rewriting history to slim the on-device clone breaks the web app. |
boot-time-budget.md |
Where the ~4.3 s to cursor goes — and why the ≤ 3 s v1.0 target is hard: one ~1.9 s full refresh is unavoidable at cold boot, so the splash is nearly free. |
sync-latency.md |
Where the ~16 s cold :sync goes — Wi-Fi + SNTP + one TLS push; why optimistic-retry cut a whole handshake, and why the rest is close to the protocol floor. |
