accessProgress (scripted, public)
<instance of nsmcp::LogService> accessProgress handle fields
Update retained progress for an access scan. Merge progress fields only while the job handle still exists, under the service mutex.
- Parameters:
- handle (required)
- Retained job or conversation handle; ownership and expiry checks still apply.
- fields (required)
- Dictionary of fields supplied by the callback or progress producer.
- Returns:
- An update result, or an empty result for an expired job.
- Testcases:
- No testcase defined.

<instance of nsmcp::LogService> poll context handle
Read the status and progress of an owned log job. Check ownership and report explicit coverage and continuation metadata under the service mutex.
- Parameters:
- context (required)
- Authenticated request context carrying the principal, grants and selected server.
- handle (required)
- Retained job or conversation handle; ownership and expiry checks still apply.
- Returns:
- A rooted JSON job-status object.
- Testcases:
- No testcase defined.

<instance of nsmcp::LogService> resolveWindow context handle
Resolve a retained job's time bounds for its owner. Validate the caller and locate an owned job under the service mutex rather than accepting browser-supplied bounds.
- Parameters:
- context (required)
- Authenticated request context carrying the principal, grants and selected server.
- handle (required)
- Retained job or conversation handle; ownership and expiry checks still apply.
- Returns:
- The retained window dictionary; unknown or unowned handles raise an error.
- Testcases:
- No testcase defined.

- Parameters:
- context (required)
- Authenticated request context carrying the principal, grants and selected server.
- handle (required)
- Retained job or conversation handle; ownership and expiry checks still apply.
- cursor (required)
- Zero-based cursor into retained results.
- limit (required)
- Maximum number of records or entries to return.
- includePeers (required)
- Whether raw peer addresses are requested; requires the additional peer permission.
- Returns:
- A rooted JSON result-page object.
- Testcases:

- Retained job or conversation handle; ownership and expiry checks still apply.
- operation (optional)
- Configured diagnostic operation to run.
- identifier (optional)
- Complete log-thread identifier, or the raw identifier field when parsing access records.
- Returns:
- A worker callback result; published evidence remains in retained job state.
- Testcases:
- No testcase defined.
