Wide-deployment Windows path without WSL2. The agentic bridge already runs
on native Python + PowerShell; the only bash dependency is the H4/H2 gate
scripts, which run under Git Bash (Git for Windows) — much lighter than WSL2.
- h4_scan now returns a status (ok|blocked|timeout|unavailable). Timeout stays
FAIL-CLOSED (block/deny). "unavailable" (no bash / gate missing) DEGRADES the
turn to observed_only and does NOT block the developer — never silently
certifies without a working gate.
- bash interpreter is configurable via CASAN_AGENTIC_BASH; gates use it.
- doctor reports bash_available / gates_runnable + a remediation warning, and
stays green (degraded, not failed) when bash is absent.
- tests: +4 no-bash cases (degrade to observed_only, tool still allowed,
non-certified finalize, injection still blocked when bash present). 34/34.
- docs: Windows guide + security guide now point to Git Bash, not WSL2, and
document the timeout-vs-unavailable distinction.

Wave 0 + Wave 1 core of the transparent agentic-client integration: a
developer types prompts normally in Claude Code / Codex while every
certified turn still carries a full H1->H7 trace and an H6 record.
- agentic_bridge.py: stdlib-only lifecycle state machine (begin/pre-tool/
post-tool/telemetry/finalize/abort + report/doctor). Single-model
invariant (never calls a model), fail-closed at the side-effect point,
admission TTL + canonical-project/session binding, atomic state under
.specify/state/agentic-sessions/, secret redaction, null-not-zero H6.
- agentic-lifecycle.schema.json: client-agnostic JSON contract.
- adapters/claude-code + adapters/codex: thin hook renderers + config
templates that call the core bridge.
- phase-agentic-bridge-tests.sh: C1-C12 acceptance + threat suite (30/30).
- devkit templates/{claude,codex} + windows/install-agentic.ps1
(install/doctor/uninstall with manifest, path-safe).
- docs/casan Windows + security/bypass guides; plan status -> IMPLEMENTED.
- harden generate-agentops-dashboard.py aggregation against null H6 costs.
