0.12.0

Changed

• ess --help lists four commands, one per area, and every verb keeps the spelling it had.
  The crates moved under crates/{specify,generate,verify,infra}/ in 0.11.1; the command surface
  now says the same thing, so where a thing is implemented and how it is spelled are one fact
  instead of two. The first level is specify, generate, verify, infra and nothing else.

• Every flat spelling is a hidden alias of its area path. ess validate --path . is
  ess specify validate --path .: the same arguments, and when the command runs, the same stdout,
  the same stderr and the same exit status, with no deprecation line anywhere. For a refusal clap
  writes — a missing required argument — and for --help, only the Usage: line differs, because
  it names the path that was typed, which is what the flat spelling has always printed. The alias
  is left out of --help only so the listing stays the four areas. Both spellings are mounted from
  one definition in the derive, so they cannot drift apart, and a test enumerates every leaf of the
  clap tree and asserts the pairing rather than a list somebody keeps up to date. Nothing is
  deprecated and no pinned caller — agentide's gate invokes ess compile and ess generate by
  name — needs changing.

  ess schema	ess generate schema
  ess build	ess generate build
  ess release	ess generate release
  ess stack	ess generate stack
  ess deployment	ess generate deployment
  ess conform	ess verify conform
  ess diff	ess verify diff
  ess impact	ess verify impact
  ess infra <operation>	ess infra infra <operation>
  ess import	ess infra import

  Two verbs share the name of their area. ess generate --path … is the flat spelling of
  ess generate generate --path …, and ess infra diagnose … of ess infra infra diagnose ….
  The generate area therefore offers the verb's five options beside its eight subcommands, and
  refuses the two written together — ess generate --path X synthesize says two things at once and
  exits 2, as it did before the area existed.
