Mission Support / 2026

Mission systems. Inspectable work.

Mission support.Made tangible.

Three interactive applications for the work behind readiness.

A maintenance blocker. An inventory discrepancy. A record that cannot be released. Explore how clear interfaces turn each into a visible decision, a defined next step and an inspectable record.

What this work can show

Workflow design, responsive application interfaces, constrained inputs, explicit state transitions, actionable validation and downloadable records. Each scenario can be reset and explored again.

How to evaluate it

Start with the seeded scenario. Try an invalid action. Complete the permitted path. Compare the screen with the export. Reset. The following pages give a concrete walkthrough for each application.

01 · Equipment readiness

Equipment readiness

See the blocker. Record the decision.

Make the path from maintenance evidence to release visible.

Open application ↗ /labs/portfolio/readinessApplication route: /labs/portfolio/readinessLocal simulation
Equipment readiness application showing synthetic facility assets, a selected asset and its maintenance gates.
Application detail · R-104 portable lighting is the starting selection. All assets and records are synthetic.
8Synthetic facility assets
5 / 2 / 1Ready / attention / held
3 gatesInspection / work / evidence

The design question

Can a coordinator explain an equipment status and identify the next permitted action without switching between disconnected records?

  • Selectable assets with search and filters.
  • Generic inspection evidence and work-order closure.
  • Reviewer release, activity history and JSON export.

Walk through the decision

  1. Reset. Inspect R-104 and name its visible blockers.
  2. Attempt release early. Inspect the reason it cannot proceed.
  3. Record inspection evidence, close the blocking work order, then record the reviewer release.
  4. Compare the asset, counts and activity with the JSON export. Reset the scenario.
What to verify
CheckAcceptance criterion
Gated releaseIncomplete required work cannot produce a released state; blank required evidence is rejected.
Coherent recordsSummary counts, selected detail and exported state agree; each accepted action is visible in activity.
Repeatable scenarioReset restores the initial records, gates and counts without retaining the previous run's actions.

Scope boundary. Ordinary facility assets and generic procedures. No diagnostics, predictive maintenance, medical-device instructions, live telemetry or real release authority. Reviewer actions are simulated, not authenticated maintenance records.

Official context.Army reporting describes maintenance accuracy and equipment reliability as important to readiness. This concept applies a general workflow pattern; it does not implement an Army program. Army maintenance report · February 9, 2026 ↗

02 · Supply accountability

Supply accountability

Every item. Every handoff.

Keep a discrepancy, its explanation and its review connected.

Open application ↗ /labs/portfolio/supplyApplication route: /labs/portfolio/supplyLocal simulation
Supply accountability application showing four synthetic supply lines, quantities and a reconciliation review workspace.
Application detail · Water filters are the starting selection. Quantities, reviewers and handoffs are synthetic.
4Synthetic supply lines
68 / 62Expected / counted
2Initial discrepancies

The design question

Can a coordinator reconcile a count without losing the reason for the change or bypassing the review before handoff?

  • Expected and counted quantities kept visible.
  • Bounded input with a required reconciliation reason.
  • Simulated second-person review and ledger export.

Walk through the decision

  1. Reset. Find the two discrepancies and inspect the water-filter line.
  2. Try an invalid or over-expected count, then a blank reason. Inspect the validation.
  3. Resolve both discrepancies. Attempt handoff before review, then complete review and handoff.
  4. Compare the ledger and decision sequence with the JSON export. Reset.
What to verify
CheckAcceptance criterion
Valid quantitiesOnly whole counts from zero through the line's expected quantity are accepted in this scenario.
Reviewed handoffResolve all discrepancies with reasons, then review before handoff. Changed counts invalidate the review.
Ledger integrityLine quantities sum to the displayed and exported totals; reset restores 68 expected and 62 counted.

Scope boundary. No physical scans, live stock system, transport routing or actual custody transfer. A simulated reviewer is not identity verification or segregation-of-duties enforcement. Over-counts are intentionally blocked; a production overage policy requires agreement.

Official context.The Army describes digital inventory and inspection workflows in its supply-chain application reporting. This independent concept does not connect to ParaLine, CheckMate, GCSS-Army or LMP. Army application preview · March 31, 2026 ↗

03 · Data exchange sandbox

Data exchange sandbox

Make every validation decision inspectable.

Expose the finding, the correction and the release decision.

Open application ↗ /labs/portfolio/exchangeApplication route: /labs/portfolio/exchangePolicy simulated locally
Data exchange sandbox showing synthetic equipment records, a payload inspector and field-specific validation findings.
Application detail · Six administrative equipment records. No real files are uploaded or transmitted.
6Synthetic equipment records
4 / 2Accepted / quarantined
0Initially released

The design question

Can a reviewer see precisely why a record failed and what rule permits or blocks its release, without treating validation as a black box?

  • Payload inspection and field-specific findings.
  • Fixture correction, revalidation and explicit review.
  • Simulated recipient policy and decision-event export.

Walk through the decision

  1. Reset. Inspect a quarantined record and its exact field-level finding.
  2. Attempt release before eligibility. Correct both fixture errors and revalidate the package.
  3. Try a denied recipient, then review and release to a permitted simulated recipient.
  4. Compare records, findings and events with the export. Reset to the original scenario.
What to verify
CheckAcceptance criterion
Useful validationInvalid records identify the affected field and a correction; accepted does not automatically mean released.
Explicit gatesA package with findings, stale validation or no applicable review cannot release; a denied recipient remains blocked.
Inspectable stateThe export matches records, findings and events; reset restores four accepted, two quarantined, zero released.

Scope boundary. Local policy and reviewer simulation only. No authentication, access enforcement, secure transfer, clinical exchange or HL7/FHIR implementation is demonstrated. The export is not immutable audit evidence. No security or compliance certification is claimed.

Procurement reference.DHA opportunity notice on SAM.gov ↗ is supplied context only. Its requirements are not assessed here. No clinical integration, compliance, endorsement or award is implied.
