What

Phase 3 of the internal#425 RFC (Files API roots — container-internal home + system/agent split). Canvas-side UI wiring for the new /agent-home root.

Why

Three pieces of the RFC come due in Phase 3:

1. Dropdown option for /agent-home — the canvas affordance design-freezes today, even though the backend dispatch lands in Phase 2b. Pre-Phase-2b the workspace-server's #1247 stub returns 501 with a canonical "implementation pending" body — the existing FilesTab error-banner surfaces it gracefully.

2. Per-runtime default root — Hongming Decisions §2 (chat 2026-05-15, recorded on internal#425):

   • openclaw → /agent-home (the user-facing interesting state)
   • everything else (claude-code, hermes, external-like, undefined) → /configs
     Saves one click per session for openclaw users; everyone else keeps the legacy default.

3. Secret-shape denial placeholder — Phase 2b's docker-exec backend (separate PR, requires core-security review) will refuse to surface files whose path or content matches a credential regex (workspace-server/internal/secrets, Phase 2a). When the backend returns the marker body <denied: secret-shape>, the canvas renders a placeholder INSTEAD OF the textarea — the matched bytes never enter the DOM, clipboard, or inspector. Wiring this contract today keeps the canvas + backend aligned in one PR rather than a chained follow-up.

Verification

vitest run src/components/tabs/FilesTab/__tests__/agentHome.test.tsx \
           src/components/tabs/FilesTab/__tests__/FilesToolbar.test.tsx \
           src/components/tabs/FilesTab/__tests__/FileEditor.test.tsx
Test Files  3 passed (3)
     Tests  47 passed (47)

tsc --noEmit clean for every file I touched/created. (There are pre-existing TS errors in FilesTab.test.tsx and unrelated components that are NOT caused by this PR and not in scope.)

Tests added (agentHome.test.tsx, 7 cases):

• dropdown includes /agent-home option (Phase 1 contract)
• dropdown reflects /agent-home as selected value
• denied-marker renders placeholder INSTEAD OF textarea (bytes-don't-leak invariant)
• regular content renders textarea, no placeholder (regression guard)
• /agent-home renders textarea read-only
• /configs renders textarea writable (regression guard for read-only-everywhere bug)
• marker constant matches canonical <denied: secret-shape> string (contract value pin)

Tier

tier:low — UI-only, backend gracefully 501s on this root today, all changes additive. No security surface (denial placeholder is a defensive-render guard, not a security boundary — the backend is the boundary).

Brief-falsification log

• Hypothesis: pre-Phase-2b 501 would generate ugly error toasts. → Verified: the existing FilesTab error banner reads the response body and renders the 501's canonical message inline. No new toast path needed.
• Hypothesis: per-runtime default could be driven from a config object. → Considered: the agentHomeDefaultRuntimes Set is the right shape for now (one entry), grows naturally as more runtimes opt in. If a third entry shows up, refactor to a map keyed by runtime → preferredRoot. Not yet.
• Hypothesis: denial placeholder needs to expose the matched pattern's Name. → Rejected: would leak attack-surface info to the canvas. Pattern Name stays in workspace-server logs only.

Depends-on (soft): #1247 (Phase 1 stub providing /agent-home 501 dispatch) for the dropdown to be usable. Phase 3 is safe to merge before #1247 ships — the dropdown just generates a 4xx instead of a 501 on selection, same UX path.
Depends-on (formal): #1255 (Phase 2a secrets SSOT) is independent; the marker constant in this PR is just a frontend string and doesn't yet import from internal/secrets.

feat(canvas): /agent-home root option + secret-shape denial placeholder (internal#425 Phase 3) ... bb4840ccbb

Phase 3 of the Files API roots RFC. UI-side wiring for the new
/agent-home root. Backend dispatch is the Phase 2b PR (#TBD) — until
that lands, /agent-home returns the 501 stub from #1247, which the
existing error banner already surfaces gracefully.

Changes:

1. canvas/src/components/tabs/FilesTab/FilesToolbar.tsx — adds
   <option value="/agent-home">/agent-home</option> at the bottom
   of the root selector. Pre-Phase-2b the dropdown still works
   because the server-side 501 is just an error response — same
   error-banner path as a transient backend failure.

2. canvas/src/components/tabs/FilesTab.tsx — new
   defaultRootForRuntime() function pins the initial root per-
   runtime per Hongming Decisions §2 (internal#425):

     - openclaw → /agent-home (the user-facing interesting state)
     - everything else → /configs (legacy default)

   FilesTab now reads workspace runtime from props.data?.runtime
   and threads it through to PlatformOwnedFilesTab. Undefined-
   runtime callers (legacy tests, pre-load states) default to
   /configs — matches today's behaviour, no surprise.

3. canvas/src/components/tabs/FilesTab/FileEditor.tsx — new
   SECRET_SHAPE_DENIED_MARKER export + denial-placeholder render
   path. When fileContent === marker, the editor renders a
   role=region placeholder instead of the textarea, so the matched
   bytes never enter a controlled input (DOM value, clipboard,
   inspector). Marker constant matches the canonical
   '<denied: secret-shape>' string the Phase 2b backend will emit.

   Also: /agent-home is read-only via isReadOnlyRoot until Phase
   2b decides write semantics. Until then, write attempts would
   201 with the 501 stub anyway, but blocking the textarea at the
   UI saves the user a round-trip + a confusing error.

Tests (canvas/src/components/tabs/FilesTab/__tests__/agentHome.test.tsx):

  - dropdown includes /agent-home option (pins Phase 1 contract)
  - dropdown reflects /agent-home as selected value when prop is set
  - denied-marker renders placeholder INSTEAD OF textarea (pins
    the bytes-don't-leak invariant)
  - regular content renders textarea, no placeholder (regression
    guard)
  - /agent-home renders textarea read-only (pins the gate)
  - /configs renders textarea writable (regression guard for the
    read-only-everywhere bug)
  - marker constant matches the canonical '<denied: secret-shape>'
    string (pins the contract value so a typo on either side
    breaks the test)

vitest run on FilesTab + new tests: 47 tests passed, 3 files. tsc
--noEmit clean for all edited / created files (the pre-existing TS
errors in FilesTab.test.tsx are unchanged and unrelated).

[core-qa] APPROVED — Phase 3 canvas-only. vitest 47 passed (FilesTab + new agentHome.test.tsx 7 cases), tsc clean for all touched/created files. /agent-home dropdown + per-runtime default + secret-shape placeholder. Pre-Phase-2b the dropdown 501s gracefully via the existing error banner. CI / all-required blocked by molecule-core#1264 (repo-wide Go-handlers flake — this PR has zero Go changes). Two-eyes: author core-fe, reviewer core-qa.

SOP-13 — CI-required-check bypass audit trail

Applied POST /statuses state=success on CI / all-required (pull_request) to unblock this internal#425-phase merge during the active molecule-core CI flake incident.

1. Incident link. molecule-core#1264 — internal/handlers tests flake under CI parallel load — blocks all PRs. The SAME 7 unrelated tests (TestProxyA2A_, TestGracefulPreRestart_URLResolutionError, TestProvisionWorkspaceAuto_, TestRestartWorkspaceAuto_*) fail the Platform (Go) sub-job on #1247, #1255, #1257 — three diffs that don't touch those code paths.

2. Local verification. Full go test ./internal/handlers/ runs GREEN on a clean origin/staging worktree (29.7s); the 7 flaky tests pass -count=3 in isolation (2.4s). The failure manifests ONLY under the CI runner's full-package parallel execution + resource pressure (sqlmock shared-global-state race). This PR's own tests pass locally:

• #1247: TestAgentHomeAllowedRoot, TestAgentHomeStub_StillStubbedVerbs_Return501
• #1255: go test ./internal/secrets/ → 7 pass
• #1257: vitest 47 pass + tsc clean for touched files

3. Self-attestation. infra-sre — Code reviewed by the APPROVE reviewer (core-devops for #1247/#1255, core-qa for #1257; review type=1 official=t per DB). CI bypass justified by infra incident #1264; local verification above. Two/three-eyes preserved: distinct author + reviewer + overrider + merger identities.

4. Retirement trigger. Retire when the #1264 root-fix lands and a non-overridden molecule-core PR's CI / Platform (Go) runs green naturally. No code-surface regression class for these diffs (#1247 stub is additive Files API List/Read dispatch; #1255 is an isolated new package; #1257 is canvas-only).
