agent-history-hygiene

Keep agent transcripts and plan files in the commit that records their feature, without leaking secrets or mutating a file while its recorder is active.

Surfaces, separated by purpose:

Surface	Question it answers
`run-specstory-session.sh`	"How do I prove the recorder exited before finalization?"
`queue-agent-commit.sh`	"How do I queue this exact authorized commit without touching live history?"
`finalize-agent-commit.sh`	"How is the exact post-session snapshot sanitized and committed?"
`find-session.sh`	"Which transcript / plan file is my current session?"
`stage-agent-artifacts.sh`	"Which exact agent files belong in the prepared index?"
`agent-commit-metadata.sh`	"Which provenance trailers belong in the commit?"
`bootstrap-project.sh`	"How do I install validation-only hooks?"
`scan-staged.sh`	"Is the effective staged index clean?"
`probe-specstory-redaction.py`	"What does SpecStory redact natively?"
