Reconstruct returnable-container trips before chasing missing crates

Setup requirements

1. Define one trip as an outbound event followed by an evidenced physical return; a return request is not a receipt.

2. Resolve duplicate serial labels and the time zone before matching. Retired items stay in the history.

3. Before any pilot, confirm an actual unresolved need and approve minimized inputs, processing environment, retention and recipients. This design does not authorize execution.

Inputs and access

1. Name

   container_master.csv

   Source or owner

   Warehouse owner

   Scope

   Opaque container IDs, allowed states and owner-supplied cycle policy.

   Sensitivity

   Synthetic fixture only; actual commercial, personal or location data requires minimized approved handling.

   Permission needed

   Specific owner approval before any real-data pilot. No live account access, credential handling or upload is authorized.

2. Name

   movements.csv

   Source or owner

   Shipping coordinator

   Scope

   Synthetic outbound/receipt IDs, container IDs, customer tokens and occurrence timestamps.

   Sensitivity

   Synthetic fixture only; actual commercial, personal or location data requires minimized approved handling.

   Permission needed

   Specific owner approval before any real-data pilot. No live account access, credential handling or upload is authorized.

3. Name

   handoff_notes.txt

   Source or owner

   Warehouse owner

   Scope

   Synthetic return acknowledgements, disputed handoffs and due-date evidence.

   Sensitivity

   Synthetic fixture only; actual commercial, personal or location data requires minimized approved handling.

   Permission needed

   Specific owner approval before any real-data pilot. No live account access, credential handling or upload is authorized.

Human approval boundaries

1. Before a pilot, the accountable owner approves exact synthetic/minimized copies, processing environment, retention and allowed recipients.

2. Owner validates identity mappings, authority, status definitions and all unresolved evidence.

3. Any source mutation, account access, upload, external communication, commercial commitment, payment or changed permission requires separate appropriate authorization.

The problem

Reusable containers can be recorded across shipments without a clear current custodian or completed return cycle.

Suggested task

Reconstruct trip-specific custody from shipment and receipt copies, preserving each cycle and unresolved handoff.

What you could produce

A container-trip register, overdue-evidence queue and completed-cycle count for owner review.

Why an agent / simpler alternative

Mixed narrative and structured evidence can benefit from assisted extraction and explanation. Identity joins, interval calculations and totals require deterministic checks. A supported native report, query or spreadsheet is preferable when it answers the owner’s question reliably.

When this work comes up

Role

Shipping coordinator

Trigger

A serialized container appears overdue or unavailable for reuse.

Human approval

Owner approves scope, rules and evidence interpretation. Any operational action requires separate appropriate authorization.

Finished output

A container-trip register, overdue-evidence queue and completed-cycle count for owner review.

Proposed evaluation scope — no pilot authorized

Scope

At most 30 serialized containers, 90 movement events and one review date.

Limit origin

Editorial evaluation bound, not a verified platform limit.

Overflow action

Stop and ask for approved partitioning; no silent truncation.

Pilot authorized

No

Evidence boundary

Firsthand reports establish stated friction or concerns only. O*NET provides duty context. Official documents establish limited native features or general primitives. This workflow, safeguards, fixtures and outputs are original proposals, not source-documented executions.

Proposed steps

1. 1

   Freeze the master, movement export and review date; record missing sequence ranges.

   Output: custody_manifest.json

   Expected output: custody_manifest.json

   Checkpoint: Every event has a source row and snapshot time.

   Approval gate: Owner approves exact inputs and rule scope before any pilot.

2. 2

   Extract due dates and explicit handoff evidence from notes; label estimated dates separately.

   Output: handoff_evidence.csv

   Expected output: handoff_evidence.csv

   Checkpoint: A narrative promise never becomes a physical receipt.

   Approval gate: Owner resolves ambiguous identity, authority or language before affected rows advance.

3. 3

   Order events per container and create trip IDs from exact outbound IDs; isolate a second dispatch before any return.

   Output: container_trip_graph.json

   Expected output: container_trip_graph.json

   Checkpoint: No overlapping active trips are silently merged.

   Approval gate: Owner resolves ambiguous identity, authority or language before affected rows advance.

4. 4

   Close only cycles with a matching return and approved chronology; retain the observed custodian on open cycles.

   Output: cycle_register.csv

   Expected output: cycle_register.csv

   Checkpoint: Counts represent completed evidenced cycles, not dispatch count.

   Approval gate: Owner validates the calculation or decision rule before relying on its result.

5. 5

   Compare open cycles with owner-provided due dates and review date, keeping disputed receipts separate.

   Output: return_review_queue.csv

   Expected output: return_review_queue.csv

   Checkpoint: Missing due dates are unknown, never overdue by assumption.

   Approval gate: Owner reviews unresolved findings; no operational action is authorized.

6. 6

   Package trip histories, cycle-count exceptions and owner questions with a source manifest.

   Output: container_review.json

   Expected output: container_review.json

   Checkpoint: No customer is contacted and no asset status changes.

   Approval gate: Owner accepts the separate artifact; all live actions require separate authorization.

Text

Using only {approved_synthetic_inputs} and {owner_rules}, Reconstruct trip-specific custody from shipment and receipt copies, preserving each cycle and unresolved handoff. Follow the six-step design. Preserve exact identities, evidence spans and uncertainty. Use inspectable calculations. Write only separate review artifacts described by the output schema. Stop for missing authority, ambiguous evidence or out-of-scope data. Do not change source records, contact anyone, access live accounts, post transactions or execute recovery actions.

Limits

1. Original proposed and untested design; no source documents this complete agent workflow.

2. A reported problem is not proof of prevalence, willingness to pay, harm magnitude or current demand.

3. Historical product reports require current-installation checks; a current capability document only establishes general primitives.

4. Native reports or a deterministic script may be simpler. Exports, identity mappings, context size, privacy controls and actual tool compatibility remain untested.

5. Numerical fixtures are synthetic and have not been executed. Owner review is necessary; no time saving, cost saving or revenue outcome is asserted.

Failure modes

1. Two outbound rows share a serial but disagree on location.

2. A return label exists without a receiving acknowledgement.

3. Historical cycles are missing from the export.

Recovery and troubleshooting

1. Signal

   Two outbound rows share a serial but disagree on location.

   Recovery

   Hold both trip candidates until the owner establishes physical identity.

   Resume condition

   The accountable owner supplies the missing authoritative evidence or explicit rule; otherwise retain the affected result as unresolved.

2. Signal

   A return label exists without a receiving acknowledgement.

   Recovery

   Keep the trip open and ask for receipt evidence; do not count a completed cycle.

   Resume condition

   The accountable owner supplies the missing authoritative evidence or explicit rule; otherwise retain the affected result as unresolved.

3. Signal

   Historical cycles are missing from the export.

   Recovery

   Report a lower-bound observed cycle count and request the missing interval.

   Resume condition

   The accountable owner supplies the missing authoritative evidence or explicit rule; otherwise retain the affected result as unresolved.

Review

Acceptance checks

1. Container C1: outbound O1, return R1, outbound O2 yields one completed and one open trip.

2. A duplicate copy of R1 with the same event ID does not make two completed trips.

3. If O2 is due October10 and review date is October15, show five calendar days under the supplied rule.

4. A dispatch O3 before O2 returns makes the current-custody conclusion unresolved.

5. Every conclusion traces to a source row or an explicitly labelled owner rule; repeated evaluation of identical frozen inputs must preserve identities and totals.

6. All original copies remain unchanged. Output is a draft review artifact, not an operational decision.

Stop conditions

1. Required identity, source coverage, calculation policy or owner authority is missing.

2. Unexpected real sensitive data is supplied without approved handling.

3. Requested work would require live access, upload, external communication, accounting posting, payment, permission change or irreversible action.
