+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/

+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=

+# Why this workflow exists: publish-workspace-server-image builds and
+# pushes a new platform-tenant :<sha> to ECR on every merge to main,
+# but running tenants pulled their image once at boot and never re-pull.
+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin
+# endpoint that performs a canary-first, batched, health-gated rolling
+# redeploy across every live tenant. Implemented in molecule-ai/
+# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
+# (feat/tenant-auto-redeploy, landing alongside this workflow).
+#
+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/
+# molecule-ai/platform-tenant). GHCR was retired 2026-05-07 during the
+# Gitea suspension migration. The canary-verify.yml promote step now
+# uses the same redeploy-fleet endpoint (fixes the silent-GHCR gap).
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.
+#   2. This workflow fires via workflow_run, calls redeploy-fleet with
+#      target_tag=staging-<sha>. No CDN propagation wait needed —
+#      ECR image manifest is consistent immediately after push.
+#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
+#      period. Canary proves the image boots; batches follow.

+
+# Auto-refresh staging tenant EC2s after every staging-branch merge.
+#
+# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
+# the :staging-latest tag. Sister workflow exists for prod (rolls
+# :latest after canary-verify). Both share the same shape — just
+# different CP_URL + target_tag + admin token secret.
+#
+# Why this workflow exists: publish-workspace-server-image now builds
+# on every staging-branch push (PR #2335), pushing
+# platform-tenant:staging-latest to GHCR. Existing tenants pulled
+# their image once at boot and never re-pull, so the new image just
+# sits unused until the tenant is reprovisioned.
+#
+# This workflow closes the gap by calling staging-CP's
+# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
+# batched, health-gated SSM redeploy across every live staging tenant.
+# Same endpoint shape as prod CP — only the host differs.
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes on staging branch →
+#      new :staging-latest in GHCR.
+#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
+#      to propagate the new tag.
+#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
+#      need a sub-canary inside it). Soak still applies to the first
+#      tenant in case of bad-deploy detection.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>
+# of a known-good build.

- *    user-facing interesting files for that runtime live in
- *    `~/.openclaw/` inside the container, which `/agent-home` maps to
- *    via the Phase 2b docker-exec backend).

- *    → `/configs` (the legacy default — managed config that flows
- *    through the per-runtime indirection in
- *    workspace-server/internal/handlers/template_files_eic.go).
- *
- *  When the runtime is undefined (legacy callers that don't thread
- *  `data` through, or a workspace whose runtime field hasn't loaded
- *  yet) the default is `/configs` — matches today's behaviour, no
- *  surprise.
- *
- *  Note on `/agent-home` pre-Phase-2b: the backend short-circuits
- *  with HTTP 501 and the canonical "implementation pending" body.
- *  The tab renders empty + the error banner explains. This is by
- *  design — lets us land the canvas UX before the backend ships,
- *  per the RFC's phased rollout. The 501 is graceful: it doesn't
- *  poison error toasts or generate "workspace not found" noise.

-//
-// Root cause: the runtime builds its AgentCard from config.name
-// (workspace/main.py:198), and config.name is read from the
-// CP-regenerated /configs/config.yaml whose `name:` field is the raw
-// workspace UUID — NOT the friendly name the operator sees. The friendly
-// name IS captured: POST /workspaces and PATCH /workspaces/:id (the
-// canvas Details tab) write it to the trusted workspaces.name DB column.
-// But /registry/register stores the runtime-supplied card verbatim
-// (registry.go: `agent_card = EXCLUDED.agent_card`), so the stored card
-// served at /.well-known/agent-card.json and returned to peers via
-// agent_card_url ends up with name = UUID, description = "", role = null.
-//
-// Fix shape (deliberately minimal, no contract weakening): when the
-// runtime-supplied card's `name` is empty or equals the workspace UUID
-// (the placeholder the runtime had no better value for), the PLATFORM —
-// not the agent — substitutes the friendly value from the trusted
-// workspaces row. Identity stays platform-controlled: the agent never
-// gains the ability to self-set its own name/role; the platform sources
-// it from the operator-controlled DB column. We only ever FILL gaps
-// (empty / UUID-placeholder); a card that already carries a real
-// friendly name is never downgraded.
-//
-// list_peers / the /registry/:id/peers endpoint already resolve display
-// names from workspaces.name directly (discovery.go / mcp_tools.go
-// `SELECT w.id, w.name, ...`), so peer_name in delivered message tags
-// was already correct — this fix closes the remaining surface: the
-// agent_card blob itself (canvas Agent Card / Skills view, peer
-// agent_card_url fetches, the well-known card).
-//

-//
-// Why a dedicated env-var pair instead of reusing GITEA_USER / GITEA_TOKEN:
-// the provisioner's forensic #145 denylist (provisioner.scmWriteTokenKeys)
-// strips any env var named GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN /
-// GITLAB_TOKEN / GL_TOKEN / BITBUCKET_TOKEN from tenant container env
-// before docker run. That denylist is by exact key name, so the same
-// token survives transport when shipped under the generic
-// GIT_HTTP_USERNAME / GIT_HTTP_PASSWORD names that the askpass helper
-// reads first (scripts/git-askpass.sh in each template-*). The username
-// half stays an identifier (the persona's Gitea login), the password
-// half carries the bytes from the persona token file.
-//
-// The fallback pair GITEA_USER / GITEA_TOKEN is ALSO set — GITEA_USER
-// survives the denylist (it's an identity, not a credential) and
-// GITEA_TOKEN is the no-op write that buildContainerEnv will drop.
-// Both pairs in lockstep means the askpass helper's GIT_HTTP_*-first /
-// GITEA_*-fallback chain works regardless of which lane lands first in
-// the container env on any future provisioner refactor.
-//
-// Idempotent: existing GIT_HTTP_USERNAME / GIT_HTTP_PASSWORD keys are
