2.0.0a2 — the field-report alpha

PEP 440 pre-release (--pre or ==2.0.0a2 to install; stable stays 1.14.5). Everything here was earned by the first real 2.0.0a1 deployments.

• Proposals explain themselves before offering "dismiss": every generated modernize proposal carries a what line (what a QA gate / deliverable / standing condition IS), and the modernize report + cz_dream's blocked-on-triage state state the triage semantics verbatim — dismiss is a personal, gitignored seen-it that returns on material change; nothing edits the repo. Born from a field session where the human rightly refused to dismiss an unexplained gate proposal.
• A zero baseline is anomaly-shaped, not a fact: the digest's baseline line and preflight's tests gate (warn, never fail) now say with one voice that a runner exiting 0 while collecting nothing is usually a broken runner. Born from a field repo where "Baseline: 0 tests" had normalized a Node-24-broken suite into invisibility.
• Init warns when the target is $HOME (hooks wired there run in every session on the machine).
• Pre-release engines pin their portable wiring (clauderizer[mcp]==<version>) — closes the a1 caveat where alpha-inited repos were silently served by stable; plus the audit's changelog parser now speaks PEP 440, and the fleet skill's guidance carries the measured D-079 figures and the worker branch-point verification.

Suite 1571 passing (+7 skips); new guards armed red-first; full matrix green on the tagged sha.
