Add concise fault tolerance documentation to CLAUDE.md and the passes
README covering error accumulation, tryRecord wrapping, and the
distinction between validation vs infrastructure passes. Remove the
detailed planning document now that the work is complete.
Cleans up feature flags that do not have an active experiment and which
we don't currently plan to ship, one commit per flag. Notable removals:
* Automatic (inferred) effect dependencies / Fire: abandoned due to
early feedback. Shipped useEffectEvent which addresses some of the
use-cases.
* Inline JSX transform (experimented, not a consistent win)
* Context selectors (experimented, not a sufficient/consistent win given
the benefit the compiler already provides)
* Instruction Reordering (will try a different approach)
To decide which features to remove, I looked at Meta's internal repos as
well as eslint-pugin-react-hooks to see which flags were never
overridden anywhere. That gave a longer list of flags, from which I then
removed some features that I know are used in OSS.
More snap improvements for use with agents:
* `yarn snap compile [--debug] <path>` for compiling any file,
optionally with debug logs
* `yarn snap minimize <path>` now accepts path as a positional param for
consistency w 'compile' command
* Both compile/minimize commands properly handle paths relative to the
compiler/ directory. When using `yarn snap` the current working
directory is compiler/packages/snap, but you're generally running it
from the compiler directory so this matches expectations of callers
better.
Autogenerated summaries of each of the compiler passes which allow
agents to get the key ideas of a compiler pass, including key
input/output invariants, without having to reprocess the file each time.
In the subsequent diff this seemed to help.
