Resolves#14. ApplyTierConfig now reads TIER{2,3,4}_MEMORY_MB and
TIER{2,3,4}_CPU_SHARES env vars, falling back to the compiled defaults
agreed in the issue:
- T2: 512 MiB / 1024 shares (1 CPU) — unchanged baseline
- T3: 2048 MiB / 2048 shares (2 CPU) — new cap (previously uncapped)
- T4: 4096 MiB / 4096 shares (4 CPU) — new cap (previously uncapped)
CPU_SHARES follows Docker's 1024 = 1 CPU convention; internally the
value is translated to NanoCPUs for a hard allocation so behaviour
remains deterministic across hosts. Malformed or non-positive env
values silently fall back to the default.
Behaviour change note: T3 and T4 previously had no explicit cap.
Operators who relied on unlimited can set very large TIERn_MEMORY_MB /
TIERn_CPU_SHARES values; a follow-up can add unset-means-unlimited
semantics if required.
Tests:
- TestGetTierMemoryMB_DefaultsMatchLegacy
- TestGetTierMemoryMB_EnvOverride (covers malformed + zero fallback)
- TestGetTierCPUShares_EnvOverride
- TestApplyTierConfig_T3_UsesEnvOverride (wiring)
- TestApplyTierConfig_T3_DefaultCap (documents the new cap)

Resolves#12. The claude-code SDK stores conversations in
/root/.claude/sessions/ and Postgres tracks current_session_id, but the
container filesystem was recreated on every restart — next agent message
failed with "No conversation found with session ID: <uuid>".
Add a per-workspace named Docker volume (ws-<id>-claude-sessions) mounted
read-write at /root/.claude/sessions. Gated by runtime=claude-code so
other runtimes don't pay for a path they don't use. Volume is cleaned up
in RemoveVolume alongside the config volume.
Two opt-outs discard the volume before restart for a fresh session:
- env WORKSPACE_RESET_SESSION=1 on the container
- POST /workspaces/:id/restart?reset=true (or {"reset": true} body)
Plumbed via new ResetClaudeSession field on WorkspaceConfig +
provisionWorkspaceOpts helper so the flag stays request-scoped (not
persisted on CreateWorkspacePayload).

Resolves#17.
Part A: scripts/cleanup-rogue-workspaces.sh deletes workspaces whose id
or name starts with known test placeholder prefixes (aaaaaaaa-, etc.)
and force-removes the paired Docker container. Documented in
tests/README.md.
Part B: add a pre-flight check in provisionWorkspace() — when neither a
template path nor in-memory configFiles supplies config.yaml, probe the
existing named volume via a throwaway alpine container. If the volume
lacks config.yaml, mark the workspace status='failed' with a clear
last_sample_error instead of handing it to Docker's unless-stopped
restart policy (which otherwise loops forever on FileNotFoundError).
New pure helper provisioner.ValidateConfigSource + unit tests.
