Mechanism (named, not a flake): the provision-timeout sweeper flips a workspace provisioning→failed at 10m (claude-code). A slow cold-boot (EC2 image pull + LLM preflight) can finish AFTER the flip and start heartbeating — but the heartbeat handler recovered status from offline/provisioning/awaiting_agent→online, with no failed branch. agent_card is written unconditionally, so a healthy, serving workspace stayed stuck showing failed forever.

This is the root of the intermittent multi-provider e2e "boot failures": minimax preflights slower than kimi → more often crosses the 10m budget → flipped to failed → registers+serves fine while status never recovers. A live heartbeat is authoritative (the agent IS running), so recover failed→online (guarded AND status = 'failed' so it can't override removed).

Test: TestHeartbeatHandler_FailedToOnline (mirrors the provisioning→online recovery test).

APPROVED — recovers a slow-but-healthy workspace from a premature provision-timeout 'failed' flip. Mechanism named (minimax preflight > 10m budget); a live heartbeat is authoritative. Guarded transition; mirrors the existing provisioning/awaiting_agent recoveries. Tested.

APPROVED (security) — status state-machine only; guarded WHERE status='failed', no new surface.

The provision-timeout sweeper (registry/provisiontimeout.go) flips a workspace
to 'failed' when it sits in 'provisioning' past DefaultProvisioningTimeout
(10m for claude-code). But a slow cold-boot — EC2 image pull + LLM preflight
on a cold worker — can finish AFTER the flip and start heartbeating. The
heartbeat handler already recovers status from offline/provisioning/
awaiting_agent → online, but had NO 'failed' branch, and agent_card is written
unconditionally — so a healthy, serving workspace stayed stuck showing
'failed' forever.

This is the mechanism behind the "intermittent multi-provider e2e boot
failures": minimax preflights slower than kimi, so its workspaces more often
cross the 10m budget, get flipped to 'failed', then register+serve fine while
status never recovers. A live heartbeat is authoritative (the agent IS
running), so recover 'failed' → 'online'. The `AND status = 'failed'` guard
keeps it conditional (won't override 'removed').

Test: TestHeartbeatHandler_FailedToOnline (mirrors the provisioning→online
recovery test). Not a flake — the mechanism is named and fixed.

APPROVED on bde3248d2d — rebased onto clean main (earlier red was a clobbered base from a cross-branch cp; now purely additive, full handlers suite green locally).
