Investigation Review Hub Gap Analysis

Investigation Review Hub Gap Analysis

This skill solves tasks that ask for a structured JSON gap / remediation analysis of a single legal-investigation matter (grand jury or SEC subpoena). Each task gives you:

• a prompt describing the matter and deliverable,
• input/payloads/answer_template.json — the exact output schema (required keys, field types, enum choices, ordering rules, numeric precision),
• a context payload (request_context.json / review_scope.json / matter_context.json) with the matter id, client, and category labels,
• environment_access.md — the hub connection details and allowed endpoints for this task.

The deliverable is one JSON object that conforms to the template. No prose outside the JSON.

Source of record

Use only the Investigation Review Hub described in the task's environment_access.md for business evidence. Read the base URL, API key header, and allowed endpoint list from that file at solve time — do not hardcode them and do not inspect local environment source files, database files, seeds, manifests, or any answer/evaluation files. If a read-only SQL query endpoint is offered, prefer it for precise matter_id-filtered queries (it takes a sql string, optionally with params).

The hub's logical model (filter every query by the task's matter_id — the hub holds many matters and cross-matter contamination is the primary trap):

Method

1. Load the contract first

Read answer_template.json fully before gathering data. It defines: required top-level keys, per-record required keys, enum choices (issue_type, severity, status, source_status, production_impact, action_type, owner, priority, etc.), ordering rules, and numeric precision. Every value you emit must be drawn from these enums or you lose the whole record.

2. Gather evidence per matter

For the task's matter_id, pull every endpoint (filtered by matter_id). Pay special attention to:

• remediation-actions — this is the key to materiality (see step 3).
• review-documents flagged with miscoded_nonresponsive, zero_claim_contradiction, safety_escalation, personal_device, post_subpoena_erasure, deleted_channel, archive_available — these anchor findings.

3. Identify MATERIAL records (the core heuristic)

A record is material and belongs in the answer iff it is targeted by a dedicated remediation action. Remediation actions come in two flavors:

• Real actions (ACT-…-NNN, non-noise): description says "Review and remediate before next production certification." Their target_ref is the material record.
• Noise actions (ACT-…-NOISE-NNN): description is "Routine action included as realistic operational noise" and target_ref is a bare category code. Exclude these and their targets.

Non-material records (exclude from findings/risks/issues and from metrics) carry tell-tale notes:

• "Review team marked this item for follow-up but not immediate remediation"
• "Review manager requested re-sampling before escalation"
• "Finding is similar to escalated records in another matter"
• "Privilege sample has ordinary review variance"
• "Entry included to create similar labels across matters" / "Entry creates a similar label…"
• "…has no unresolved production impact" / "No production-impacting issue has been escalated yet"
• "Potential issue was remediated by archive collection" (already remediated — not a current gap)

Material records are exactly the target_refs of the non-noise remediation actions. One material record → one finding / top_risk / issue / privilege_correction. Use the stable hub record ID (source_id, event_id, finding_id, entry_id, doc_id) as the record's ID and list supporting IDs in source_refs / record_refs / blocking_refs (sorted ascending).

4. Compute metrics — material-only, strict block

The metrics object is scored as a strict all-or-nothing block: one wrong value zeroes the whole block. Count only material/escalated records, not every record with that issue_type:

• unlogged_privilege_docs = withheld − logged for the material incomplete-log privilege entry only (non-material incomplete-log entries are NOT counted).
• miscoded_responsive_doc_count = count of docs tagged miscoded_nonresponsive that anchor a material finding.
• third_party_waiver_doc_count = docs from the material third-party-waiver privilege entry.
• miscoded_privileged_doc_count = doc_count of the material miscoded_privilege QC finding.
• lost_personal_device_count / uncollected_board_source_count / uncollected_personal_source_count = count of material sources of that type/status.
• *_event_count = count of material retention events of that status.
• *_box_count = box volumes of material destroyed/post-hold events (0 when the destroyed source is not measured in boxes).
• categories_with_open_gaps / categories_with_open_risk / categories_with_any_gap_or_loss = sorted unique category codes touched by the material records.
• rolling_production_ready / production_ready = false when any material open gap exists.
• All counts are whole integers; use 0 when not applicable.

5. Map hub values → template enums

The hub's action_type and owner vocabularies do not match the template enums — you must map. Common mappings (verify against each task's enum list):

risk_level / severity: align to the remediation action's severity (P1→high, P2→medium) when available; otherwise judge by impact (lost post-hold source ≈ critical/high).

production_impact: lost source → source_lost; not collected → source_missing; incomplete privilege log → withheld_unlogged; privileged docs coded non-privileged → privilege_exposure; over-designation → recode_needed; miscoded responsive / zero-claim → underproduced or not_produced; archive available → source_available.

issue_type: erased/wiped post-subpoena device → preservation_failure/personal_source_gap; un-collected messaging → personal_source_gap/collection_gap; incomplete privilege log → privilege_log_gap; third-party forwarding → third_party_waiver/privilege_waiver; privileged coded non-privileged → privilege_miscoding; missing required record → missing_required_record; deleted archive with backup → archive_available; bid-email zero-claim → responsiveness_miscode (or the template's zero_claim_contradiction equivalent where offered).

6. Ordering and ranks

Apply the template's ordering_rules exactly: sort by stable ID ascending, by priority_rank / rank ascending (1 = highest), and category codes ascending within every list. Order actions P1 before P2, P2 before P3; within the same priority, by action_id / target_ref ascending. priority_rank / rank is a contiguous integer sequence starting at 1.

7. Validate before returning

• Every required top-level key present; every record has every item_required_keys field.
• Every enum value is in the template's list (a single invalid enum forfeits the record).
• Counts are integers; null only where the template allows "string or null".
• withheld_count − logged_count = unlogged_count.
• retention cutoff_date = event_date + retention_period_months.
• Return exactly one JSON object, no surrounding prose.

Hard-won cautions

• Filter by matter_id on every query. Issue tags and labels repeat across matters; the note "Requires matter-level filtering because similar issue labels appear across matters" is a literal warning.
• Material = has a non-noise remediation action. This single rule determines record inclusion and most metric counts. When unsure whether a non-actioned record is material, it almost certainly is not.
• The metrics block is all-or-nothing. Re-derive every count from the material set; do not sum across non-material entries.
• Record matching is field-by-field strict. A record scores only if every field (including every enum) matches the expected answer — so map enums deliberately and keep source_refs/category lists exactly sorted.
• jq precedence: when you assign a list and sort in one expression, parenthesize the right side: .x = (([new] + .x) | sort_by(.id)). A bare | sort_by(…) after an assignment binds to the whole object and silently produces wrong output.
• Do not call any judge/feedback endpoint during test solving — it is train-only and rejects test task ids.
