Highlights

Closes a contract-consistency gap in the v0.9.62 Implicit Visual Session Contract (Codex P2 from PR #33). The navigate recovery branch for NO_OWNED_TAB now records the implicit visual-session lifecycle tick on success, matching the existing open_tab / switch_tab bootstrap paths. Before this fix, an agent's very first navigate call (no owned tab yet) would proceed without ever starting or refreshing the implicit visual session, even though visual_reason and client were required on the call.

This is a Chrome-extension-only patch. The MCP server ([email protected]) and the showcase site are unchanged from v0.9.63.

What's fixed

• extension/ws/mcp-bridge-client.js — The navigate + NO_OWNED_TAB recovery branch now mirrors the open_tab / switch_tab post-dispatch pattern: await the dispatch, on success === true extract dispatched.tabId, then call _recordVisualSessionTickIfPresent and _clearVisualSessionIfFinal. Failed dispatches do not record a tick (no overlay for a failed action). Result: all three bootstrap entry points (open_tab, switch_tab, navigate-bootstrap) now uniformly start / refresh the implicit visual session.

What changed in tests

• tests/mcp-visual-session-contract.test.js and tests/visual-session-schema-lock.test.js now fail loud with an actionable remediation message (npm --prefix mcp run build) when mcp/build/tools/manual.js is older than mcp/src/tools/manual.ts. A stale build had previously masquerade as a "contract hole" by running pre-Phase-255 compiled code that lacked validateVisualSessionFields.

Version bump

v0.9.63 was a showcase-only release; the Chrome extension stayed at 0.9.62. This release lifts the extension surfaces to 0.9.64:

• package.json
• extension/manifest.json (name + version)
• showcase/angular/package.json (lockstep, no showcase code change)

Compatibility

• No protocol or schema changes. Existing agents and MCP clients continue to work unmodified.
• To see the fix, reload the FSB Chrome extension. No MCP server redeploy is required.

Verification

• 79/79 mcp-visual-tick-lifecycle, 66/66 recovery-tools-bootstrap, 16/16 visual-session-agent-scoped, 30/30 agent-tab-resolver, 23/23 ownership-error-codes, 116/116 mcp-visual-session-contract, 314/314 visual-session-schema-lock.
• Staleness guard verified: touched build mtime to 2020 → both tests bail with actionable error; after npm --prefix mcp run build both pass.
• CI on the release commit: extension ✅, mcp ✅, showcase ✅.
