…de CLI Replace the v1 Bash/YAML tool with a zero-dependency Node.js (ESM) CLI that applies LLM-authored changesets deterministically, with no possibility of silent misapplication. Format: a fenced-Markdown carrier (.pxp.md) with SEARCH/REPLACE edit blocks, plus create/delete/rename/run ops. Fence-first parsing keeps arbitrary source (tabs, backticks, nested fences) verbatim. Matching (safety-critical, pure): Pass 1 byte-exact after whitespace/CRLF normalization; Pass 2 indent-normalized exact match with re-indentation. No similarity/fuzzy path exists. Ambiguity and no-match both fail loudly with a nearest-miss repair packet. --strict disables Pass 2. Executor: git-checkpointed atomic apply — full dry-run before any write, ordered apply, hard rollback to checkpoint on failure, commit with a PXP-Changeset sha256 trailer on success. Run ops are refused without --allow-run. CLI: validate / plan / apply / prompt, with --strict --allow-run --json --keep-on-fail --no-commit --no-color. Terraform-style terminal report plus a token-capped JSON repair packet. Docs: rewritten SPEC.md and README.md for v2, new PROMPT.md planner contract (printed by `pxp prompt`), updated CLAUDE.md/AGENTS.md, and a Claude Code integration skill. Removes v1 pxp.sh, test_pxp.sh, and example_changeset.yml. Tests: 54 node:test cases across parser, matcher (property-style), validator, executor (fault-injection/atomicity), reports, and acceptance (dogfood apply, pack-size < 50KB, cold validate < 1s, no-fuzzy-code gate).
