Experimental features¶
Features that ship but are not default product promises. Experimental ≠ invisible.
Status vocabulary: EXPERIMENTAL — enable deliberately; expect sharper edges.
| Feature | Enablement | What it does | Limitations | Why not default |
|---|---|---|---|---|
| Watch | OCCAM_WATCH_MCP=1 |
Re-check a URL over time; history chain | No daemon (agent polls); store races; unsigned history ≠ history_verified |
Costly; persistence/concurrency limits |
| Crosscheck | OCCAM_CONSENSUS_MCP=1 |
Multi-source / multi-vantage comparison (source agreement) | Verdict is computed, not a “consensus proof”; same-process/egress limits | Expensive (2+ extracts); easy to overread |
| Batch | OCCAM_BATCH_MCP=1 |
Queue many URLs | No Receipt v1 on the batch envelope; store races; retention limits | Operator/server mode; not a casual agent default |
| Failure atlas | OCCAM_ATLAS_MCP=1 |
Session-local failure telemetry | Not proof a host is a “dead end” | Diagnostic, not a trust layer |
| Browser interact | OCCAM_BROWSER_ACTIONS_MCP=1 |
Declarative click/type/scroll then materialize | Max 16 steps; typed text redacted; no raw page JS; never cached | Automation surface; keep off unless needed |
| Resumable crawl MCP | — | Not shipped | Use occam_map + occam_digest, or the operator CLI occam research (budgets, resume, cancel; not a new MCP tool) |
A universal crawler is a separate product surface |
Forbidden readings¶
- Crosscheck agreement is not proof of correctness (“consensus proof” forbidden).
- Watch
history_verifiedrequires every entry signed and verified; hash-chain integrity alone is a different signal. - A typed wall is not a CAPTCHA bypass. Use a session profile or accept
ok:false.
