pond

The contributed library collection: opinionated, domain-shaped libraries you vendor and import. Vendoring is the dependency primitive. Pin a git ref, vendor the source.

hale fetch

Tiers are a taxonomy, and the numbering has gaps on purpose: 4, 6 and 7 are backlog nobody has needed yet. The HTTP client, the router and metrics graduated to the standard library and ship as std::http and std::metrics with no import; pond keeps tracking copies for existing pins. Editor tooling lives elsewhere: the tree-sitter grammar is tree-sitter-hale and the language server ships inside the hale binary.

Tier 0: internals
`_util/*`	intfloat, decimal_float, duration_int, kvpack, rowbuf: shared primitives
Tier 0: infrastructure
`crypto`	HMAC-SHA256, SHA-256, ECDSA P-256, CSPRNG, hex
`subprocess`	fork/exec with pipes, timeout, try_wait + signal
`term`	terminal control: color profiles with auto-downgrade, ANSI escapes, raw mode
`math/matrix` · `math/stats`	dense matrix, matmul, online moments
`units`	exact physics, chemistry, engineering and computing unit catalogues, with optional quantity types; needs the unit dialect merged after v0.22.0
Tier 1: data + web
`db`	backend-neutral DbDriver interface (Go database/sql shape)
`pq`	Postgres driver: pgwire v3 over TCP, + pool
`sqlite`	SQLite driver via @ffi: prepared statements + rows
`sessions` · `jobs` · `migrations`	cookie sessions, job queue, schema runner
Tier 2: observability
`tracing`	span tree mirroring the locus tower
`logfmt` · `supervisor`	structured log sinks, restart strategies
Tier 3: realtime
`websocket`	RFC 6455 client + server-side upgrade
`realtime/nats`	NATS core + JetStream client, and a std::bus adapter that carries a program's topics over NATS with at-least-once delivery and an ack audit; in-memory fake for tests
Tier 5: agents
`agent/llm`	Anthropic / OpenAI clients with SSE streaming
`agent/tools` · `conversation` · `sandbox` · `embeddings`	tool registry, chat history, code sandbox, vector store
`ml/neural`	tiny NN trainer
Tier 8: devx
`tui`	Elm-shaped full-screen TUI runtime: typed input events, cell-grid diff renderer, widgets
Superseded by the stdlib
`http/client` · `router` · `metrics`	tracking copies kept for existing vendored pins; new code should use std::http and std::metrics
