Give each endpoint its own credential and fix the review findings on the server
Per-PC credentials (replaces the 09-14 client-certificate attempt): - POST /api/endpoints/enroll issues a credential to a PC that matches exactly one computer by hostname and BIOS serial and has none yet. Anything else (unknown or duplicate hostname, serial mismatch, already enrolled) waits as a request an admin approves or rejects. The agent's persisted nonce binds an approved request to the PC that asked. - One auth helper serves every agent route. With X-Endpoint-Credential the asset comes from the credential and a request naming another PC gets 403 ASSET_MISMATCH. The shared key still works for PCs that have not enrolled, is refused (401 SHARED_KEY_REFUSED) for any PC that has, and can be switched off. A revoked credential gets 401 CREDENTIAL_INVALID so the agent re-enrolls. - The core collector accepts the credential for the computers, printers and endpoints collectors through two new plugin hooks exposed on shopdb.api (contract 0.33.0), and refuses the shared key for enrolled PCs. - Admin API: enrollment list, approve, reject, revoke (un-enroll), settings. Migration API: per-PC readiness with blockers, and upgrade waves that package the agent once and queue the existing agent upgrade per PC. - Migration 0023 creates endpointcredentials, endpointenrollrequests and endpointmigrationwaves, drops the certificate columns from assets where test databases have them, and renames app_fingerprint to appfingerprint. 0021 and 0022 keep their ids but no longer alter the core assets table. - Removed: client_cert.py, certificate renewal, the unauthenticated /test/client-cert route, nginx client certificate forwarding and the agent certificate script. The client-cert header could be forged on IIS, the key was readable by users, and the shared key remained a fallback. - GET /settings/server-cert returns the SPKI SHA-256 pin for GE-Enforce. Review fixes: - report_command_result used g without importing it; every result was a 500. - collect_log refuses setup answer files, appsettings, agent directories and key files at enqueue. - Fleet alerts: alerttimeout and alertfleet agree with the migration, the scope is validated and a malformed scope no longer reaches the whole fleet, and the ack race no longer raises NameError. - A refused break-glass override leaves no hold and no audit row. - Agent upgrade checks locks and permissions before repackaging, and writes the package atomically. - Server certificate upload validates the pair before replacing files; generation no longer builds an openssl config from user input; audit rows are actually written. - Health evaluation runs in a savepoint so a caught error cannot lose the check-in. - Required-app policies are found by appid, survive renames, and deleting an app deactivates policies that still name it. The UI and API now say such a policy only takes effect inside a business policy. - Backfill handles duplicate fingerprints and rolls back a failed batch. - Plugin settings routes skip a plugin whose hook raises. - The setup token is no longer printed to the log. - The naming gate checks top-level files again and handles odd file names. - Removed root scratch scripts, one of which carried a token. - Rewrote the fleet alert scheduling and app delta tests on real fixtures. |

Add one-click agent self-upgrade from the endpoint detail page
An operator could see that an endpoint was behind the published build but had no way to act on it. update_app resolves against Application rows, and the agent lives in the version store, so there was nothing to push. Bridge the two: the staged build is packaged and registered as a reserved Application row, and a managed PowerShell script is seeded to install it. The endpoint downloads that package over the existing collector-authenticated app-package route, so no parallel delivery path is introduced. The new route prepares the delivery and then DELEGATES to enqueue_endpoint_command as a digest-pinned run_script. It deliberately does not implement its own enqueue: a second path would duplicate, and eventually drift from, the endpoint lock, the Configuration Policy gate, stale-command reaping and the at-most-one-in-flight rule. A fleet-wide agent swap is the last action that should skip a quarantine check. Tests pin that delegation rather than only the happy path. Because it lands as run_script, the caller needs endpoints.runscript on top of endpoints.agentupdate. That is intended: this delivers arbitrary SYSTEM PowerShell by the same mechanism as any other script push. The audit event is written only on an actual 201, so a refused push does not record an upgrade that never happened. Replacing the agent is self-modifying the control plane - the process receiving the command is the one being swapped. The script therefore re-launches itself detached and exits immediately, because the agent runs run_script as a direct child and holds its stdout/stderr pipes while waiting on it. Expect the command to report queued rather than success: the process that would report completion is stopped mid-run. Judge the result by the version the endpoint reports afterward. Tray relaunch does not use the installer's `explorer.exe <path>` trick. That works in install-shopdbagent.ps1 only because the installer runs as the user - note its own `-ne "SYSTEM"` guard. This script always runs as SYSTEM in session 0, where the hand-off reaches no shell and exits 0, so Start-Process reported success for a relaunch that never happened. It also cannot descend into the session with a token-duplicating launch: UserContextSpool documents that WTSQueryUserToken is blocked by endpoint protection on these hosts. Instead a one-shot scheduled task targets the pinned ShopFloor account, matching how the user-context spool already resolves that user, and the tray must run as that account or the mapped-drive probe reports the wrong (empty) drive table. The relaunch is verified by polling for the process rather than assumed, and stays best-effort: the Run key still starts the tray at next logon, and a late tray is not worth rolling back a good agent upgrade. panel_status now carries agentbehind/agentversion/agentcurrent so the UI gates the action on a flag rather than parsing "(behind X)" out of a label. The button is confirmed by typing UPDATE, naming both versions and the service interruption, matching how run_script and system_restart are gated. Verified on live endpoints: upgraded 1.13.0.0 and 1.15.0.0 machines to 1.16.0.0. run_script delivery, digest fetch and system context all predate 1.13.0.0, so no minimum agent version is declared for this path. |
