Summary

Root-caused from live tenant-box logs (SSM): the SaaS auto-restart/resume cycle rebuilt the re-provision payload with Name/Tier/Runtime only — never the template — so the asset-channel TemplateIdentity was empty, no config/prompts were re-fetched, and the fresh ephemeral instance came up with a 218-byte STUB config.yaml on EVERY restart. Fix: persist workspaces.template at create (additive migration) and restore payload.Template on the SaaS restart/resume paths so config.yaml+prompts re-deliver from the same template. Verified on a live ws instance (/configs/config.yaml was 218B post-restart).

Root-cause not symptom

Fixes the actual source — the restart payload never carried the template — not the stub symptom. Confirmed via box logs + on-disk state, not inferred.

No backwards-compat shim / dead code added

Additive column + a targeted payload restore gated to the SaaS path (h.cpProv != nil). Docker keeps its existing persistent-volume "do not re-apply" behavior untouched. Fail-soft: read error → "" → old behavior.

Comprehensive testing performed

TestStoredWorkspaceTemplate (sqlmock, both populated + empty). go build ./... && go vet ./internal/handlers/ && go test ./internal/handlers/ green locally (with MOLECULE_GITEA_TOKEN for the token-gated RefPinning tests).

Local-postgres E2E run

Unit-level (sqlmock) here. The full provision→restart→config-persists behavior is covered by template-delivery-e2e once deployed (it asserts config.yaml is non-stub).

Staging-smoke verified or pending

PENDING by construction — the runtime change only takes effect post-deploy. Will verify on a live tenant via SSM that config.yaml stays full (9316B) across a restart.

Five-Axis review walked

Correctness (restores the exact create-time template), Security (no new secret surface; reads a non-secret column), Idempotency (additive migration; restore is read-only), Blast-radius (SaaS-gated; Docker untouched; fail-soft), Observability (logs persist/restore).

Memory consulted

feedback_skills_are_plugins_dynamic_install, project_rfc2843_rollout_authorization, feedback_follow_dev_sop_phase1_evidence_first (each workspace + tenant has its OWN box).

## Summary Root-caused from live tenant-box logs (SSM): the SaaS auto-restart/resume cycle rebuilt the re-provision payload with Name/Tier/Runtime only — never the template — so the asset-channel TemplateIdentity was empty, no config/prompts were re-fetched, and the fresh ephemeral instance came up with a 218-byte STUB config.yaml on EVERY restart.

Root-caused 2026-06-17 from live tenant-box logs (SSM docker logs): the
auto-restart cycle (workspace_restart.go runRestartCycle + resume) rebuilt the
re-provision payload with Name/Tier/Runtime ONLY — never the template — and
passed templatePath="". On SaaS the config is delivered via the asset channel
keyed on TemplateIdentity = templateIdentityForTemplateOrRuntime(payload.Template,
runtime); with an empty template that identity is empty, no assets are fetched,
and the fresh ephemeral instance comes up with a 218-byte STUB config.yaml +
dropped prompts on EVERY restart. Confirmed on a live ws instance: /configs/
config.yaml = 218B after a plugin-install-triggered restart.

Fix: persist workspaces.template at create time (new column, additive migration)
and, on the SaaS (cpProv) auto-restart + resume paths, restore payload.Template
from it so the re-provision re-delivers config.yaml + prompts from the SAME
template. Docker keeps its persistent config volume, so it retains the existing
"do not re-apply templates on auto-restart" behavior (template left empty there).

Tests: TestStoredWorkspaceTemplate (sqlmock). go build/vet/test green locally.

This is the prerequisite for the declared-plugin boot-install (the rest of #32):
restart now knows the template, so boot can re-establish the declared plugins.
