Execution Ledger — Nkosi Felix

What this page is

This page summarizes real, dated commit history for nkosifelix.com -- not a description of intended work, but a record of what actually shipped. The source citation for every claim below is the commit ledger covering July 8-9, 2026 (76 commits, first commit 7a9590a4). The full case study is at July 8-9 Build Sprint.

Tone note: this is a proof surface, not a pitch. Every card below names its evidence source and its current verification artifact, and labels anything missing as a TODO rather than asserting it.

Proof categories

Backend Platform

FastAPI backend, evidence-gated chat adjudicator, and provider health checks shipped and hardened over two days.

Evidence source: commits 7a9590a4 (add FastAPI backend + Vercel/GitLab deployment config), 54d5f602 (add live provider health checks), 5fa96f0a (live provider health + evidence ledger + adjudicator updates).

Verification artifact: live /health and /chat/status endpoints on production.

Missing artifact: Verification needed: add screenshot/test output/live URL. See public/proof/health/latest-provider-health.json below.

Evidence-bounded chat assistant with deterministic routing, employment-sequence answering, and a dedicated Guardrail Validation surface.

Evidence source: commits bce78271 (fix chat over-rejection), 17666e70 (bound chat skill routing), 93e2f166 (redesign chat launcher, add Guardrail Validation, fix hero video reduced-motion bug), 3b52941c (answer employment sequence questions), 2f6f8246 and 45ea0633 (close chat gaps from live regression sweeps).

Verification artifact: the live Guardrail Validation section and chat widget on the homepage; backend regression suite (pytest).

Missing artifact: Verification needed: add test output/live URL. See public/proof/test-output/latest-regression.txt below.

Mobile QA

Mobile navigation, hero video, and capture-slice regressions found and fixed across a dedicated mobile hardening pass.
