Prototype parser-first PowerShell statuses

[Noisemaker111]

What changed

• adds a persistent CPU-only PowerShell AST backend and parser-first benchmark
• resolves a Bun test target against the supplied working directory and uses its unique declared test name as grounded purpose
• keeps service caching working-directory-sensitive and preserves parser source identity
• adds a development-only linguistic training loop: simulate mapped-action combinations, request proposals from an explicitly selected provider route and model, then apply only human-accepted overrides
• invalidates the earlier 86.7% usefulness audit because filename/executable restatements were incorrectly counted as useful

Exact observed operation

bun test --timeout 90000 test/codex-quest-dev-installer.test.ts

with cwd C:\Users\Jk101\Projects\JonsOCsetup returns:

Running a Bun test with a 90-second timeout to verify that every development install advances, seals and adds a new cache version without removing the old one.

The evidence is the test declaration inside the resolved file, not an LLM guess or filename rewrite.

Verification

• 41 live-status tests passed
• 5 command-model binding tests passed
• 5 command-model contract tests passed
• compileall passed for live-status and required repository paths
• real HTTP boundary returned parser output, then the same cwd-sensitive cached output
• 120-row frozen syntax benchmark: 97.5% AST parse success, 84.2% fully mapped, 13.3% literal fallback, 2.5% abstention, 100% validator pass, 2.75 ms p50
• the frozen sample has no cwd, so it does not measure purpose-resolution usefulness

No LLM, GPU, OpenCode Go, OpenRouter, or Claude call was made for this verification.

Real command-cell probe

The parser was also exercised against commands actually used in this session. It now preserves Python test discovery paths and verbosity, compile targets, GitHub Actions run/interval, Git staged filenames, commit message, push remote/branch, file basename, and text-search pattern. Bash remains explicitly unsupported by this PowerShell prototype.
