Digital public infrastructure can capture a tap in 22 languages. It cannot yet tell whether the person understood what they tapped. Journey Intelligence closes that gap — a standard for recording understanding (the comprehension artefact) and a voice engine for delivering it (Kya Likha Hai).
Proves: the same Aadhaar eKYC flow adapts its language, verbosity and voice to the person — and any screen can be read aloud in their language via Kya Likha Hai.
Pick a persona and language (try Hindi). Walk the four eKYC steps. On the consent step, tap the orange KLH button and listen. Switch language mid-flow — the narration regenerates.
Proves: a consequential action can produce a DEPA-style consent artefact (permission) paired with a comprehension artefact (understanding) — generated only after a real teach-back check.
Run “Today's flow” first — note the empty understanding slot. Switch the layer on, in Hindi. Answer the teach-back question wrong on purpose; watch it re-explain. Pass, then open “show machine record.” Fail twice: the flow pauses and writes no consent at all.
Proves: duplex voice Q&A over the same eKYC moment, answered from pre-generated cached narration (Tier 1) with live generation as fallback (Tier 2) — near-zero marginal cost for ~90% of queries.
Pick a language, tap the mic and ask aloud — “kya share hoga?”, “wapas le sakta hoon?”. Note the response latency: that is a cache hit, not a model call.
Proves: the whole stack generalises beyond eKYC — KLH, personas, L1–L4 materiality routing, Tier 1 cache vs Tier 2 live with latency and cost on screen, voice follow-ups, and a CAS gate that forces a review on consequential actions — inside an Umang-style government services app.
Pick a persona (try Rajan · Farmer). Open a service and tap Compare — Tier 1 cached (instant, $0) vs Tier 2 live (Claude → Sarvam), latency and cost side by side. Ask a follow-up by mic. Then open an L4 service (NACH Mandate) and tap the red action button: the CAS gate fires with a forced 5-second review while KLH explains the consequences aloud.
Just looking. Nothing changes, nothing is spent.
Read-only lookup. On-device, $0, nothing to undo.
Small, routine, known. Cache lookup, ~$0.
Real money, larger or unknown party. Cache, then live. Hard to undo.
Irreversible, high-stakes. Max effort + CAS gate.
The consent artefact records permission. The comprehension artefact records understanding.
Journey Intelligence is the system that makes the second one possible at a billion-user scale.
