Bug

A SaaS workspace's auto-restart re-provisions a fresh EC2 (empty /configs), but the restart lands a 218-byte stub config.yaml (no template config, no prompts/) — losing the agent's identity on every restart.

Root cause (traced live via SSM on a staging tenant)

A fresh seo-agent came online with real config, then the post-online plugin-reconcile (installing seo-all) triggered Auto-restart → fresh EC2 → config.yaml = 218B stub, even though workspaces.template='seo-agent' was correctly persisted.

config.yaml/prompts reach a SaaS box only via the config_files channel: the control-plane /cp/workspaces/provision consumes config_files (staged to SM molecule/workspace/<id>/config, fetched at boot) — the fetcher's TemplateAssets wire field is not consumed by the deployed CP at all. config_files is populated by collectCPConfigFiles walking cfg.TemplatePath.

The auto-restart called provisionWorkspaceAutoSyncLocked(id, "", nil, payload) with templatePath="" → config routed only into the dropped TemplateAssets → stub. The prior RFC#2843 #33 fix set payload.Template on restart, but that only drives the (CP-dropped) TemplateAssets path, so it never actually re-delivered.

Impact

• Prod reliability: any SaaS workspace that auto-restarts (plugin install, crash-recovery) loses its template config.yaml/prompts → degraded identity.
• CI: the template-delivery-e2e required gate flaps green/red — it races the config assertion vs the post-online plugin-reconcile restart.

Fix

On the SaaS restart, resolve the LOCAL template dir the same way first-provision does (resolveWorkspaceTemplatePath) and pass it, so the re-provision re-delivers config.yaml + prompts via config_files. Re-applying touches only template-owned, allowlisted files (config.yaml, prompts/**); user/agent paths (CLAUDE.md, MEMORY.md, .claude/**, /workspace) are excluded by IsCPTemplateAssetPath, so a persisted /configs is not clobbered. Docker keeps templatePath="" (preserve its persistent config volume).

Verify after merge (deploys to staging)

template-delivery-e2e goes deterministically green (the restart re-stub race is removed). Then unblocks #3049 (concierge create_workspace), whose own gate run was blocked by this intermittent.

SOP checklist

• Comprehensive testing performed: go build ./... clean; go test ./internal/handlers -run 'Restart|Provision' green; gofmt-clean. Root cause verified empirically (SSM: workspaces.template=seo-agent, box /configs=218B stub, provision.start template field present on both provisions, CP request struct has no template_assets).
• Local-postgres E2E run: Handlers Postgres Integration on head; pure handler change, no schema.
• Staging-smoke verified or pending: scheduled post-merge — the fix takes effect once deployed (template-delivery-e2e is a black-box test of deployed code).
• Root-cause not symptom: fixes the actual delivery channel (config_files via templatePath on restart), not the symptom.
• Five-Axis review walked: correctness/readability/architecture/security/performance.
• No backwards-compat shim / dead code added: no shim; Docker path unchanged; SaaS path corrected. (Separately notes the CP TemplateAssets field is dead — cleanup tracked, not in this PR.)
• Memory/saved-feedback consulted: feedback_no_such_thing_as_flakes (named the race mechanism), feedback_follow_dev_sop_phase1_evidence_first (SSM ground truth).

Refs RFC#2843 #33, #3049 (unblocks).

fix(provision): SaaS auto-restart re-delivers template config.yaml + prompts ... 2ba0662da6

The SaaS auto-restart re-provisions a fresh EC2 (empty /configs), but the
restart dispatched provisionWorkspaceAutoSyncLocked(id, "", nil, payload) with
templatePath="". config.yaml/prompts reach a SaaS box ONLY via the config_files
channel (CP /cp/workspaces/provision consumes `config_files`; the fetcher's
TemplateAssets wire field is NOT consumed by the deployed control-plane), and
config_files is populated by collectCPConfigFiles walking cfg.TemplatePath. With
templatePath="", config routed only into the dropped TemplateAssets → every SaaS
restart landed a 218-byte stub config.yaml (lost identity/prompts).

The prior RFC#2843 #33 fix set payload.Template on restart, but that only drives
the (CP-dropped) TemplateAssets path — it never re-delivered. This resolves the
LOCAL template dir the same way first-provision does
(resolveWorkspaceTemplatePath) and passes it, so the restart re-provision
re-delivers config.yaml + prompts via config_files. Re-applying touches only
template-owned, allowlisted files (config.yaml, prompts/**); user/agent paths
(CLAUDE.md, MEMORY.md, .claude/**, /workspace) are excluded by
IsCPTemplateAssetPath, so a persisted /configs is not clobbered. Docker keeps
templatePath="" (preserve its persistent config volume).

Root-caused live via SSM on a staging tenant: seo-agent online with real config,
then post-online plugin-reconcile triggered an auto-restart → fresh EC2 →
config.yaml = 218B stub (workspaces.template was correctly 'seo-agent'). This is
the template-delivery-e2e intermittent (races the assertion vs the restart) and a
prod identity-loss-on-restart bug.

Security/correctness review — APPROVE. SaaS auto-restart re-stub fix. Verified independently: (1) Docker safety — resolution is gated to h.cpProv != nil; self-host keeps templatePath="" (no clobber of persistent /configs). (2) Clobber safety — collectCPConfigFiles filters the template-dir walk through isCPTemplateConfigFile (config.yaml + prompts/** only); user/agent paths (CLAUDE.md/MEMORY.md/.claude/**/workspace) excluded, covered by TestStart_CollectsConfigFiles. (3) Fail-safe — absent template dir → restartTemplatePath="" (no worse than today), no nil/panic. (4) Path flows to cfg.TemplatePath (dispatch→provisionWorkspaceCP→buildProvisionerConfig→Start→collect). build + Restart/Provision tests green.

QA review — APPROVE. Root cause confirmed: CP consumes config_files only (no template_assets field), so config reaches a SaaS box via config_files (TemplatePath walk); the restart passed templatePath="" → 218B stub. Fix mirrors first-provision resolution on the SaaS branch. Follow-up (non-blocking): add a unit test asserting the SaaS restart passes the resolved dir.

APPROVED. Five-axis review complete on current head 2ba0662d.

Correctness: the restart path now restores the persisted template and resolves a local template dir only on the SaaS/cpProv branch, then passes that path into provisionWorkspaceAutoSyncLocked so cfg.TemplatePath can feed collectCPConfigFiles. Docker/self-host behavior remains templatePath="".

Robustness/security: resolveWorkspaceTemplatePath keeps resolution inside configured roots, and collectCPConfigFiles/isCPTemplateConfigFile/IsCPTemplateAssetPath constrain delivery to config.yaml and prompts/** with traversal/symlink/size checks, so this does not reintroduce user/agent state clobbering. Failure to resolve logs and preserves the prior fallback rather than panicking. Performance/readability: one stat plus existing template walk only on SaaS restart; comments are long but accurately explain the production invariant. CI was reported green; no blockers found.
