Merge pull request 'feat(claude-code): T4 host-root escalation leg + real tier-4 conformance gate (RFC internal#456 §9-11)' (#25) from feat/t4-escalation-leg-claude-code into main

T4 currently ships only the provisioner privileged-container shape;
the in-image uid-1000 agent has NO wired path to host root inside
--privileged --pid=host -v /:/host (--privileged grants caps to root,
not uid-1000; root:docker 0660 docker.sock unusable). This adds the
ADDITIVE escalation leg, preserving the uid-1000 + agent-owned-token
contract:

- Dockerfile: bake sudo + util-linux(nsenter) + docker.io CLI;
  /etc/sudoers.d/agent-t4 `agent ALL=(ALL) NOPASSWD:ALL` (0440,
  visudo-validated at build); `agent` in `docker` group. useradd
  -u 1000 + `exec gosu agent` UNCHANGED — agent stays uid-1000.
- entrypoint.sh: document the agent-owned-token half of the §10
  atomic co-sequencing contract on the existing `chown -R agent
  /configs` (token ownership NOT regressed).
- ci.yml: new `t4-conformance` job — NOT a string-match. Builds the
  real image, runs it under the EXACT controlplane tier-4 flags, and
  asserts on the RUNNING container, atomically: (a) the uid-1000
  agent attains host root (sudo nsenter --target 1 + host-fs
  write/readback through /host) AND (b) /configs/.auth_token
  owner_uid==1000. Wired into the required `validate` aggregator and
  fails closed (no skip except fork-PR short-circuit).

RFC internal#456 §9-11 / PR#474. Atomic per §10: uid-1000 enforcement
and the escalation leg ship in this one image revision.

+# Ported from .github/workflows/ci.yml on 2026-05-11 per internal#326
+# (Class-A root: cross-repo `uses:` blocker for Gitea 1.22.6 —
+# feedback_gitea_cross_repo_uses_blocked).
+#
+# Root cause of the main-red CI on this repo:
+#   The .github/ original used
+#     uses: molecule-ai/molecule-ci/.github/workflows/validate-workspace-template.yml@main
+#   which Gitea 1.22.6 rejects (DEFAULT_ACTIONS_URL=github → 404 against
+#   the remote repo even though it lives on the same Gitea instance).
+#   Gitea reads .github/ as a fallback when .gitea/ is absent
+#   (reference_per_repo_gitea_vs_github_actions_dir), so the .github/
+#   workflow was firing on Gitea and failing in 1s.
+#
+# Fix shape: inline the validation logic directly. The canonical
+# validator in molecule-ai/molecule-ci already self-clones into the
+# runner via a direct HTTPS `git clone` step (validate-workspace-template.yml
+# does this verbatim) — so the inline port is just "do that clone +
+# invoke the validator script in-place", preserving the
+# single-source-of-truth property (each CI run still fetches the
+# canonical validator fresh).
+#
+# Four-surface migration audit (feedback_gitea_actions_migration_audit_pattern):
+#   1. YAML — no `workflow_dispatch.inputs`; no `merge_group`; preserved
+#      `on: [push, pull_request]` from the original. Added workflow-level
+#      env.GITHUB_SERVER_URL (feedback_act_runner_github_server_url).
+#   2. Cache — `actions/setup-python` `cache: pip` preserved; works against
+#      Gitea's built-in cache server when runner.cache is configured.
+#   3. Token — uses auto-injected GITHUB_TOKEN (Gitea-aliased). Validator
+#      job needs only `contents: read` (no write to issues/PRs).
+#   4. Docs — anonymous git-clone of molecule-ci (no token in URL); the
+#      molecule-ci repo is public on the Gitea instance.
+#
+# Fork-PR semantics: validate-runtime is intentionally skipped on fork
+# PRs because pip-install + docker-build + adapter-import are arbitrary
+# code execution. Internal PRs and main pushes get full coverage. The
+# `github.event.pull_request.head.repo.fork` field is null for non-PR
+# events; the `!= true` comparison defaults to running.

 ## Language

+## Workspace ownership tier — T4 (top-tier)
+
+**T4 (top-tier) workspaces grant full host control.** The Docker socket is mounted into the container; the runtime is started with `--privileged`; the workspace owner can `docker exec` into siblings on the same host and read/write anything the host kernel will let it touch.
+
+What this means in practice:
+
+- The container's home directory `~/.claude/` (and its `sessions/`, `session-env/`, `settings.json`) is persisted across restarts via a host bind mount. Anything you (or the SDK) write there survives container churn — but ownership can drift.
+- If you see `EPERM` / "permission denied" on `~/.claude/` writes after a restart — particularly on `settings.json` or anything under `sessions/` — the volume picked up `root:root` ownership from a prior boot or a newer claude-code release wrote subdirs the entrypoint didn't pre-create.
+- Recovery (do this yourself; you have the rights): `sudo chown -R agent:agent ~/.claude/`. The entrypoint already runs a recursive chown unconditionally on every boot, so a restart also clears it — but `sudo chown` is faster and doesn't drop the active session.
+- The provisioned `~/.claude/settings.json` is informational: it documents that `permission_mode='bypassPermissions'` is the canonical operating mode, which is also set programmatically in `claude_sdk_executor.py` (the file is NOT the source of truth — the SDK kwargs are).
+
+If `cat ~/.claude/settings.json` returns `No such file or directory` you're on a workspace image older than 2026-05-15 — restart picks up the new entrypoint and stubs the file in place.
+
+## Knowing your own model
+
+Use the `get_runtime_identity` MCP tool to know what model you actually are. It reads the live process env (`MODEL`, `MODEL_PROVIDER`, `MOLECULE_MODEL`, `ANTHROPIC_BASE_URL`, `TIER`, `WORKSPACE_ID`, `ADAPTER_MODULE`) and returns the resolved values — no HTTP call, always works, always permitted by RBAC. Do NOT guess from your system prompt or from `requirements.txt`; the operator may have routed you to a different model via persona env between boots.
+
+## Editing your own agent_card
+
+Use the `update_agent_card` MCP tool to update this workspace's `agent_card` on the platform. Pass a JSON object — the platform validates required fields server-side. The change is broadcast as an `agent_card_updated` event so the canvas reflects the new card live. The tool is gated on `memory.write` capability, so read-only agents won't accidentally rewrite the card; T4 owners always have this capability.
+
 ## Runtime wedge integration
 
 The `runtime_wedge` module (in `molecule_runtime`) is the universal cross-cutting holder for "this Python process can no longer serve queries — only a workspace restart will recover." It surfaces unrecoverable wedges to two consumers:
