Scenario summary¶

A premium support organization maintains an approved diagnostic-bundle evidence-handling guide covering intake labeling, checksum verification, restricted-field tagging, chain-of-custody note requirements, secure-upload quarantine handling, retention-clock start rules, and approved analyst-access caveats for customer-provided bundles. When that guide is revised, support leads need one bounded digest artifact, Diagnostic-Bundle-Evidence-Handling-Change-Brief-r4, that explains what changed in the newly approved guidance, which prior evidence-handling expectations still carry forward from the superseded baseline, and which adjacent controlled context records remain aligned or unresolved before the next lead briefing. Source precedence is explicit: the newly approved evidence-handling guide and its publication metadata are authoritative, the prior approved baseline is the only comparison anchor for carry-forward statements, and adjacent controlled context records such as the chain-of-custody checklist, secure-upload retention schedule, restricted-field taxonomy, and analyst-access control matrix may clarify continuity but cannot override the changed guidance. The workflow must stop at informational briefing handoff for support leads; it must not recommend escalation routing, adjudicate diagnostic readiness, approve evidence exceptions, direct customer communication, or execute any evidence-handling step.

Target systems / source systems¶

Evidence-handling guidance repository containing the newly approved diagnostic-bundle guide revision, the superseded baseline version, revision metadata, and controlled publication status
Prior baseline archive preserving the last approved evidence-handling guide and earlier digest lineage used to distinguish new instructions from carried-forward expectations
Chain-of-custody checklist library defining the approved custody fields, transfer-note requirements, and evidence-receipt checkpoints referenced by the revised guide
Secure-upload retention schedule and quarantine-control register covering approved retention clocks, temporary hold rules, purge checkpoints, and upload-lane identifiers for diagnostic bundles
Restricted-field taxonomy and redaction-reference table defining the current approved evidence classes, masking labels, and prohibited free-text categories that remain in force around the changed guide
Analyst-access control matrix and reviewer-role roster that describe the approved support-lead, specialist, and restricted-review access boundaries cited by the digest
Support governance briefing workspace where Diagnostic-Bundle-Evidence-Handling-Change-Brief-r4, source links, and unresolved questions are posted for support leads
Change notification feed that emits the authoritative evidence-handling guide publication event and triggers digest refresh only after the revised guide is approved

Why this instance matters¶

This grounds the pattern in a support workflow centered on revised evidence-handling guidance rather than escalation-path changes, diagnostic readiness judgments, or recommendation packets. Support leads often inherit bundle-handling expectations through habit and scattered control references, so a raw guide update does not clearly show which custody, retention, and restricted-field assumptions still stand and which adjacent records need follow-up before teams rely on the revision. The instance shows how a bounded change digest can improve governance continuity for diagnostic evidence handling while remaining clearly outside routing, adjudication, customer communication, and operational execution.

Likely architecture choices¶

flowchart LR feed["Change-notification feed"] --> agent["Bounded digest agent compare revision, baseline, and control context"] guidance["Guidance repository approved guide revision and publication metadata"] --> agent baseline["Prior baseline archive"] --> agent checklist["Checklist library"] --> agent retention["Retention / quarantine register"] --> agent taxonomy["Taxonomy table"] --> agent access["Access-control matrix"] --> agent agent --> workspace["Briefing workspace Diagnostic-Bundle-Evidence-Handling- Change-Brief-r4"] workspace --> stop["Bounded briefing stop"]

Event-driven monitoring fits because the digest should refresh from the authoritative guide publication event instead of waiting for manual policy review or ad hoc lead questions.
A tool-using single agent can compare the revised guide with the prior approved baseline, retrieve the narrow surrounding control set, and assemble Diagnostic-Bundle-Evidence-Handling-Change-Brief-r4 with claim-to-source traceability.
Bounded delegation works because support governance can predefine the allowed source boundary, digest template, and audience while humans remain responsible for any downstream evidence-handling interpretation or case-specific action.
The digest should preserve an explicit split between changed evidence-handling instructions, unchanged carry-forward context from the prior baseline, and unresolved alignment gaps in checklist, taxonomy, retention, or access-control records.

Governance notes¶

Only the approved evidence-handling guide repository, prior approved baseline, controlled checklist library, retention and quarantine register, restricted-field taxonomy, analyst-access matrix, briefing workspace, and authoritative change notification feed should drive the digest; draft comments, case chatter, or informal reviewer interpretations remain out of scope.
Diagnostic-Bundle-Evidence-Handling-Change-Brief-r4 should cite only the excerpts, identifiers, and context needed for support-lead briefing so customer-sensitive bundle details, analyst identities, or upload-lane specifics are not copied more broadly than necessary.
Visible unresolved blockers and open questions should remain in the briefing artifact, including the still-unmapped RF-27 restricted-field label in the redaction table, a retention schedule entry that still references the retired secure-upload-usw2-legacy bucket, an unsigned checksum-verification appendix update for emergency bundle splits, and a pending access-matrix clarification on whether temporary malware-review coverage inherits the new custody-note wording.
If the revised guide conflicts with the current chain-of-custody checklist, references a retention control that is not yet updated, or depends on a taxonomy or access-control record with stale lineage, the workflow should surface that mismatch explicitly rather than smoothing it over.
Audit records should preserve the triggering guide revision id, prior baseline id, cited checklist, taxonomy, retention, and access-matrix versions, plus any human clarification appended before the digest is shared with support leads.
The workflow boundary ends at the informational briefing artifact; evidence exception approval, bundle intake triage, escalation routing, customer messaging, and live evidence handling remain outside this pattern.

Evaluation considerations¶

Percentage of approved diagnostic-bundle evidence-handling guide revisions that produce Diagnostic-Bundle-Evidence-Handling-Change-Brief-r4 with complete version, source-boundary, and provenance traceability
Reviewer correction rate for changed-guidance summaries, carried-forward evidence-handling context, or unresolved-question framing during support-lead briefing review
Rate at which checklist, retention, taxonomy, or access-control mismatches are surfaced explicitly before support leads rely on the digest
Usefulness of the digest for helping support leads understand what changed and what still applies without forcing them to reconstruct the guide revision and adjacent controls manually
