v0.4.3 - Phase acceleration planner and practical agent workflow hardening

PIC v0.4.3 is a practical release for teams and AI agents that need to check agent outputs, route evidence, keep unresolved work visible, and decide the next safe verification step.

What changed

• Added the phase acceleration planner: pic phase plan, pic phase gap, pic phase trajectory, pic phase runbook, pic phase benchmark, and pic agent accelerate.
• Added request-file workflows so agents and CI can run deterministic checks from stable JSON inputs.
• Added compact output for agent and CI use: accepted status, workflow usability, unresolved obligations, top bottlenecks, safe next commands, schema references, and promotion blockers.
• Expanded JSON Schema and portability examples so non-Python implementations can validate against the same contract.
• Improved documentation and examples for installed-package use, agent communication, phase planning, safety boundaries, and production readiness.
• Hardened release checks around version consistency, distribution artifacts, citation metadata, publish safety, and CI stability.

Recommended starting commands

pic agent check --compact --text "Candidate packet: preserve residuals."
pic agent runbook --profile development
pic agent accelerate --compact --text "Candidate packet: preserve residuals."
pic phase plan --request examples/phase_acceleration/phase_acceleration_request.json --compact

Safety boundary

PIC is a workflow verification toolkit. It helps agents preserve residual ledgers, find bottlenecks, route verifier work, and reuse checked work items. It does not prove real ASI, physical outcomes, oracle truth, or hidden promotion from accepted or workflow_usable to settled. External inputs and agent messages remain candidates until the configured verifier, identity, provenance, nonce, and residual policies pass.
