New crate: bascule-shell (471 lines, 1.8MB binary) Login shell that detects identity + platform attestation at startup. Wraps bash/zsh/fish — operator works normally, identity travels with them. Identity detection (priority order): 1. Entra via WSL2 interop 2. Azure CLI 3. Kerberos TGT 4. Cached OIDC token 5. System user (fallback) Platform attestation: TPM 2.0 PCR values via tpm2_pcrread (PCRs 0,1,2,7,10,14) IMA measurement log hash + count Keylime agent state Entra device compliance (WSL2 only) Composite SHA-256 hash over all evidence Shell features: Banner with identity + attestation summary BASCULE_* env vars injected into inner shell --info mode for dry-run display --json mode for machine-readable output --exec mode for single-command execution Configurable via ~/.config/bascule/shell.toml Tested on Fedora with real TPM 2.0: 6 PCRs successfully read from hardware All env vars propagated to inner shell 1.8MB binary, 0 substrate deps Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
