Your presence - baki.io

[SCAFFOLD - Baki to revise] A mirror isn't surveillance. A mirror is a room you can leave.

Metrics

presence states: 5 — unseen · glanced · read · dwelled · returned. Classifier in src/lib/presence.ts with thresholds parked as named tokens for retuning.
consent tiers: 3 — ambient (session-only) · local (on this device) · telemetry (local + opt-in aggregate echo, server POST pending).
curated device reads: 6 — Device class · OS · viewport · screen · language · referrer. All surface as human strings; the raw User-Agent is never shown.
server round-trips: 0 — Every value on this page is computed from local storage on your device. Nothing travels off-device until telemetry tier + a server wire-up both land.

Cards

Ambient tier
[SCAFFOLD - Baki to revise] sessionStorage only. Tan fades when you close the tab. Default tier; no consent dialog to dismiss. Dense mirror of the current visit, nothing more.
Local tier
[SCAFFOLD - Baki to revise] localStorage on this device. Tan survives visits. The rail remembers where you've been; the dashboard remembers how you arrived. Opt-in via Preferences → Presence.
Telemetry tier
[SCAFFOLD - Baki to revise] local + an anonymous aggregate echo. Server-side k-anonymized counts only; no individual record leaves your device. Wire-up pending.

Process

Arrival — You land on a node. Presence starts at `unseen`; no record exists yet.
Engagement — PresenceTracker accumulates focus-time, scroll depth, interaction count into a per-node record while you read.
Classification — computePresenceState promotes the record through glanced → read → dwelled as thresholds cross. A second-day revisit flips to `returned`.
Mirror — This dashboard reads every record on every refresh. The consent tier decides whether records survive the tab close.
Lifecycle — Export writes a JSON snapshot. Forget wipes the keyspace. Dissent resets just the consent tier. Every action starts on-device; none of them require a server.

The module below mirrors every baki.* key stored on this device - device context, consent tier, visit records, canvas trajectory - rendered as a dense monospace dashboard rather than a dump of raw fields. Each row is a curated read: Desktop · 1920×1080 · English rather than the literal User-Agent string. Nothing travels off-device unless you opt into the telemetry tier (still pending a server wire-up).

Three buttons sit at the bottom. Export downloads a JSON of everything shown above so you can keep your own copy. Forget wipes every baki.visitor.v1.* record and every baki:prefs:* key, then reloads. Dissent resets only the consent tier back to ambient without touching records or prefs - next visit will re-prompt.

Change tier directly in Preferences → Presence; the dashboard reflects the switch immediately.
