Interface & Integration — ICD + Test + Bring-up

A systems-integration execution repo that shows how I translate HW + Controls + Facilities constraints into a repeatable bring-up + verification plan — with pinned versions, interface control, and evidence-based test closure.

What this demonstrates (in ~60 seconds):

• ✅ Baseline + control interfaces using an ICD + IO map
• ✅ Prevent integration churn using Release Lock + Version Matrix
• ✅ Execute bring-up with commissioning checklists + entry/exit criteria
• ✅ Close requirements using RTM (requirement → test → evidence)
• ✅ Triage failures using severity rubric + workflow

Evidence outputs (proof this repo runs)

After running the commands below, this repo produces evidence files:

• IO map validation output: docs/evidence/io_map_validation_output.md
• RTM status summary: docs/evidence/rtm_summary_output.md

---

Quick start (run + generate evidence)

Validate interface consistency (IO map):

python src/validators/validate_io_map.py data/sample/io_map.csv

Summarize requirements closure (RTM):

python src/tooling/rtm_summary.py docs/requirements/RTM.csv

Save outputs as evidence:

mkdir -p docs/evidence
python src/validators/validate_io_map.py data/sample/io_map.csv > docs/evidence/io_map_validation_output.md
python src/tooling/rtm_summary.py docs/requirements/RTM.csv > docs/evidence/rtm_summary_output.md
