Hydra

v0.7.12l — Hydra

What landed

• Mode-aware StoaChain tab — empty servers see only the Medusa Panel with capacity-gated install buttons; non-empty servers see the full sub-tab set with Medusa as the chainweb-container browser.
• Unified Install Wizard — one component, mode: 'prime' | 'slave' prop decided by which Medusa button the operator clicked. Same step skeleton for both paths; steps that need no operator input render as AUTO+CONFIRM cards.
• Unified Convert Wizard — auto-detects direction (Prime→Slave or Slave→Prime) from the node row, preserves cluster-id + mining pubkey + warmup state through the conversion, and offers an editable Identity step with live uniqueness validation.
• Medusa Panel rebuilt as the per-container browser — accordion rows for each chainweb on the host, action buttons (Convert / Migrate / Remove) gated by container state, and capacity-aware "+ Add SLAVE NNN" for multi-tenant hosts.
• First-class Migrate action — same-server cross-drive data relocation via rsync, with target-drive capacity panel, fresh-admin-confirm wrap, post-success state cleanup, and tls/ alongside data/.
• Operator-locked install gates — Prime requires ≥2 physical cores + ≥8 GB RAM; Slave option requires capacity for ≥2 segregated containers (≥12 GB RAM, ≥8 vCPU after host reserve). Server-side guard on every install endpoint.
• AddSlaveWizard, ConvertToPrimeWizard, and ConvertToSegregatedWizard deleted. One state machine, one fresh-admin-confirm wiring, one port-allocation path — every install + convert flow lands in one place going forward.

Operator notes

A server's StoaChain tab becomes mode-aware. Empty server: only the Medusa Panel renders, with install buttons whose visibility is gated by host capacity. Non-empty server: Medusa Panel becomes a chainweb-container browser (one collapsible row per container) plus the existing Status/Control/Flags/Identity subtabs.

Two adaptive wizards back the panel: one Install Wizard that takes a mode: 'prime' | 'slave'prop (decided by which Medusa button the operator clicked), and one Convert Wizard that auto-detects direction (Prime→Slave or Slave→Prime). Both wizards show the same step skeleton; steps that don't need operator input render an "Auto: hub determined X — confirm & continue" panel instead.

Mixed Prime+Slave is forbidden — a server is in exactly one mode at any time, and state transitions go through the wizards. No backdoor mutations from row pages. Removing the last chainweb returns the server to Empty mode and the tabs collapse to Medusa-only on next render. Migrate (move data dir to another drive on the same server) becomes a first-class container action alongside Convert and Remove.
