Atlas Ops Reporting

Atlas Commerce Operations reporting & correction

You are given an analytical (or correction) request against the Atlas Commerce Operations service and must emit one JSON object that conforms exactly to a provided answer_template.json. These tasks share one structure; follow the procedure below rather than improvising per task.

1. Read the three authoritative inputs (in this order)

1. environment_access.md — the base URL, Authorization: Bearer <token>, and the list of available endpoints. Always read it fresh; never hardcode the URL or token — they are supplied per task.
2. The request payload input/payloads/<something>_request.json — this is the authoritative business spec: cohort/scope, business definitions, rollups, rounding, money/FX policy, ranking order, and the status/risk thresholds. When the prose prompt and the payload seem to differ, the payload governs; the prompt.txt is only framing.
3. input/payloads/answer_template.json — the exact output contract (a JSON Schema). It fixes the key names, types, enum spellings, ID regex patterns, array minItems/maxItems, ordering notes, and rounding (multipleOf / decimal_places / precision). additionalProperties:false means emit exactly the required keys and nothing else.

Map every business concept named in the request to a concrete answer field before writing any SQL.

2. Discover the data model — do not guess columns

• GET /api/schema and GET /api/data-dictionary to learn the real table and column names and, critically, field semantics (which column is the canonical/effective value, which flags production vs test, how status / currency / timestamps are represented).
• The SQL gate rejects introspection (sqlite_master, information_schema, version() and similar are refused as "query rejected"). Get structure only from the schema/data-dictionary endpoints, then query the real business tables.
• If a GET returns a transient {"error":"service error"}, retry a few times.

3. Query via POST /api/sql (read-only)

• Body {"sql": "<one SELECT>"}; response is {"columns":[...],"rows":[[...]],"row_count":N,"truncated":bool}.
• Dialect is SQLite (3.46). Use single-quoted string literals.
• Always check truncated. If true, aggregate/paginate so no rows are silently dropped — every count, list, and rate must be over the full cohort.
• A {"error":"query rejected"} means the query violated the read-only / allowlist gate (introspection, non-allowed function, or a write on /api/sql). Rewrite as a plain SELECT over business tables.
• Prefer computing metrics in SQL, then verify each headline number with an independent query (e.g. eligible == complete + incomplete).

4. Apply the cohort and cutoff exactly

Every task narrows to a precise population before any metric. Apply all stated filters, in combination:

• Production population only (exclude test/non-production) when stated.
• Time window (created/opened/service window): treat timestamps as exact UTC boundaries and honor the stated inclusivity (inclusive → >=/<=).
• As-of cutoff: evaluate every state (open/delivered/resolved/complete) as of the cutoff, not "now". A thing done after the cutoff counts as not-yet-done.
• Membership predicates (segment, region, tier, campaign, "has an effective scan in the named batch at/before cutoff", etc.) exactly as written.
• Use the effective/canonical value where raw and canonical layers exist; the data dictionary says which column that is.

5. Compute metrics per the written definitions

See references/metric-and-output-rules.md for the full checklist. Core rules:

• Rates: numerator/denominator exactly as defined; keep failing/incomplete items in the denominator when the spec says so. Compute unrounded for comparisons and ordering; round only the final reported value to the stated decimals.
• Aggregate ratios (e.g. units-per-hour): sum numerator and denominator across the group then divide — never average per-row ratios.
• Median: sort the values; for an even count average the two central values.
• Money / FX: convert each row with the daily rate for that row's own service_date and currency, compare/aggregate in the reporting currency (USD), and round the displayed total to the stated decimals.
• Exact ID lists: return the business IDs matching the predicate, unique, matching the template's regex, sorted as specified (usually id ascending).

6. Ranking (top-N / worst-N)

Order on the unrounded metric, applying the full multi-key sort in the stated order and ending with the id tie-break (almost always id ascending). Return exactly the required count (minItems == maxItems). Round each reported metric only after selection.

7. Tiered status / risk classification

Evaluate the tiers in their listed order and assign the first tier whose condition holds — the tiers run best→worst (e.g. HEALTHY→WATCH→CRITICAL, STABLE→PRESSURED→AT_RISK, LOW→MODERATE→HIGH, CONTROLLED→ELEVATED→SEVERE), and the final tier is the catch-all "otherwise". Test conditions against unrounded rates, and respect strict vs inclusive wording ("at least"/>= vs "below"/<).

8. Correction tasks (only when the request explicitly approves one)

Some requests approve a single minimal canonical correction (identified as one raw-vs-canonical contradiction) and ask for pre- and post-correction metrics.

• Identify the one affected row/field; change the canonical field only via POST /api/sql/transaction. Never modify raw source values, source-identity fields, or unrelated rows.
• Write the audit record using the request-supplied reason_code, actor, audit_id, correction_key, and corrected_at; read it back via GET /api/correction-audit.
• Success rule: exactly one business row and one audit row committed, and a post-change SELECT confirms the new canonical value → correction_status: "APPLIED". Any other outcome → "NOT_APPLIED" reporting the values actually observed.
• Compute the backlog/metrics both before and after per the template.
• If the request does not approve a correction, stay strictly read-only.

9. Write answer.json

• Exactly one JSON object, the required keys only, nesting/types per the template. Integers as integers; rates/amounts as numbers at the exact decimals; enum strings spelled exactly; arrays at the required size and order.
• No commentary, markdown, or extra fields in the file.
• Before finishing, re-validate the object against answer_template.json and re-derive each headline number with a second query. See the checklist in references/metric-and-output-rules.md.
