From 4bb184b935388109479a30675d35027e27fc071e Mon Sep 17 00:00:00 2001 From: thanhnv Date: Thu, 23 Jul 2026 20:44:07 +0700 Subject: [PATCH] feat(harness): implement Plan-20 transparent agentic client bridge 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.
