Uqbar JS component processes

We use componentize-js to package up a .js file into a WASM binary. Support for JS-based WASM binaries was added in PR #72. Currently, only 0.1.0 is known to work.

Usage example: hello.js -> hello.wasm

MVP PM persistence

PM persists all its desired metadata immediately upon change

When a new process is spun up, e.g., the new metadata is written to disk immediately.

When starting a new process, specify whether to persist it or not

Kernel types thinking

Sending to loop

Would be nice to change current system (send_requests(), send_response(), send_response_with_side_effect_result() with enforcement and erroring happening in kernel) to a type-based system.

E.g., return to a single send_() function: send_to_loop() or something. That function takes as input

VFS proposal

Goals

1. Human-readable, central store-of-truth where metadata can be attached to files.
2. A translation layer between WASI filesystem sys calls and our filesystem.

Types

App distribution non-proposal writeup

Vision

Applications are registered on-chain. App store/aggregator is backed by chain for security (think: chain version of signing a binary) & off-chain for storage & distribution of files.

Flows

SQL thinking

The goal

Use an existing library and replace the calls out to filesystem to be routed to our filesystem.
