Bun-exclusive roadmap

Phases

B-0 — Inventory freeze


Work	Publish inventory + matrix; pin Bun docs version; classify each API exclusive vs shared
Exit	No known high-traffic Bun-only API missing from inventory without a “deferred” note
Status	Docs in progress (this tree)

B-1 — Files


Work	`Bun.file`, `Bun.write`, path edge cases on Linux, basic Blob interop
Exit	Smokes + matrix `supported` for file core
Depends on	Engine can run modules; host fs capability

B-2 — HTTP server


Work	`Bun.serve` fetch-handler server; routing basics; TLS later
Exit	Hello-world server smoke; load test optional
Depends on	B-1 helpful; net host

B-3 — SQLite + SQL


Work	`bun:sqlite`; then `Bun.sql` / Postgres client if still exclusive
Exit	CRUD smoke; parameterized queries
Depends on	B-1

B-4 — Utilities cluster


Work	`Bun.hash`, `Bun.password`, `Bun.Glob`, `Bun.spawn`, `Bun.sleep`, inspect/deepEquals/semver
Exit	Unit tests per API; matrix updates
Depends on	B-0

B-5 — Cloud + long tail


Work	S3 client; remaining inventory rows; FFI; test runner API
Exit	Every inventory row maps to a matrix row or named group (matrix Coverage check passes); experimental rows labeled
Depends on	B-2…B-4 as needed

B-6 — Dogfood


Work	First-party sample apps: static file server, sqlite API, S3 backup script
Exit	Key rows `dogfooded`
Depends on	B-2, B-3 at minimum

Suggested priority order

Bun.file / Bun.write
  → Bun.serve
  → bun:sqlite
  → Bun.hash / Bun.password / Bun.Glob
  → Bun.spawn
  → Bun.sql
  → Bun.s3
  → bun:ffi / bun:test / Bun.build

Risks

Risk	Mitigation
Inventory churn	Version pin + release-note diffs
Accidental Node reimplementation	Exclusive filter review in PR template
`bun:jsc` expectation	Document refuse / scripty-native substitute
Scope explosion via `Bun.build`	Keep in B-5; do not block B-1…B-3

Relationship to I1

Prefer implementing exclusive APIs that need modern syntax after ES-5. File and hash APIs can start earlier with limited language features.
