What the code actually +does today, checked against TST Desk's source, is [`docs/reality-check.md`](docs/reality-check.md). +Decisions are in [`docs/decisions.md`](docs/decisions.md). + +**Status:** pre-alpha, private use. The pure-JVM core is built and tested. The Android app is +written against framework APIs and type-checked, and has not yet been run on a phone. + +## How it drives the phone + +1. The accessibility service flattens the screen into numbered controls (hints) with stable + identities, and renders them as a data block the model reads. +2. The model answers with exactly one line of a closed grammar: `tap 7`, `type 3 "on my way"`, + `scroll 4 down`, `done "..."`. Nothing else executes. Hints not on screen are refused. +3. The policy pack decides the tier: silent, once per task, every time, or refused. Every + rule is data in `policy/policy.yaml`, and `policy/cases.yaml` pins every case. +4. Tier 2 actions (send, call, pay, delete, install, share, settings, notification reply, + leaving the goal's apps) show a card on the phone with the target highlighted, plus a + notification with Approve and Deny. No answer is a deny. +5. The kill switch is a Quick Settings tile and a Stop action on the task notification. ## Layout | Path | What | Builds where | |---|---|---| -| `core/` | Pure-JVM Kotlin: action grammar, observation format, hint table, policy enforcer, meter, audit schema, redactor, wire clients.

This repo builds a native assistant surface anyway, +because the product is different: a default-assistant-role app that drives the phone through +the accessibility tree cannot be a web page. Home mode still attaches to tstd over its +existing WebSocket protocol as a client; nothing in tstd is forked. This is a scope change +and is recorded as one; TST Desk's decision stands for TST Desk. + +## TM-002 (2026-09-07) The policy pack is rules-only data; tstd's classifier is not reused as code + +tstd's decision classifier is fifteen Python predicates plus a model call for ambiguous +tool calls, keyed on paths, hosts and mutation flags. None of that maps to phone verbs. The +plan's own hedge ("if the current classifier turns out to be model-assisted anywhere, that +part is rewritten as rules first") applies: `policy/policy.yaml` is an ordered rule table +over facts the phone can compute without a model, and `policy/cases.yaml` is the shared +conformance suite. Mapping to the desktop axis: silent ≈ A/auto, every ≈ B/ask, +refused ≈ never. Tier "once per task" has no desktop equivalent. + +## TM-003 (2026-09-07) Global navigation is never app-scoped + +`back`, `home` and `recents` are the way out of any app, including one that is not on the +allowlist or outside the goal set. They are refused on the keyguard and on secure screens +like everything else. Without this a task that lands in the wrong app could only `ask`. + +## TM-004 (2026-09-07) Append-only audit is enforced by SQLite triggers + +TST Desk enforces INSERT-only by a source-scan test; the file itself is writable. The phone +adds BEFORE UPDATE and BEFORE DELETE triggers that abort. This is stronger than the desktop; +a future desktop migration that drops a table would have to drop its triggers first. The +desktop schema (v1, v2) is replayed verbatim; the phone's tables are a v3 migration on top. + +## TM-005 (2026-09-07) Framework APIs only in the app for now + +No androidx, no Compose in our own sources. The overlay card, notifications, tile and +settings screen use framework views. Reason: the sources can then be type-checked on a +machine with no Android SDK (`tools/androidcheck` against Robolectric's framework jar), and +the dependency surface a person has to audit stays small. OkHttp's Android artifact brings +androidx.annotation and androidx.startup transitively, so `android.useAndroidX=true` is set; +that is the whole AndroidX footprint. Compose can come when the assistant surface grows. + +## TM-006 (2026-09-07) Cleartext only to `*.ts.net` + +tstd serves plain `ws://`; Tailscale is the transport security. The app's network security +config refuses cleartext everywhere except MagicDNS names, so Home mode is configured with +the box's MagicDNS name, never a bare tailnet IP. + +## TM-007 (2026-09-07) `screen ask` is Tier 1 (once per task), not Tier 0 + +The plan's Tier 0 list does not name it. A screenshot leaving the phone to a cloud vision +model is a privacy event; one approval at task start covers it. In Device mode it is local +and the same tier costs nothing. + +## TM-008 (2026-09-07) No tst-cu-mcp Android target in this iteration + +The plan's Appendix C was not supplied, and the sidecar's backend contract is pixels and +global coordinates with a single-node `hit_test`; a hint grammar does not ride it. The +phone's own observe/act path is built directly on the accessibility tree. A device-side +socket for tstd is future work and will reuse `core/net` (bind rules, token, handshake). + +## TM-009 (2026-09-07) Timeout is deny, on the phone, always + +tstd only denies an approval on timeout when the workspace policy sets +`approval_timeout_seconds`; by default it waits forever. The phone's approval surface owns +its own timer (`approval_timeout_seconds` in the policy pack, 45 s) and answers deny itself, +in every mode. In Home mode that means the phone sends an explicit deny to tstd. diff --git a/gradle.properties b/gradle.properties new file mode 100644 index 0000000..8b4e82d --- /dev/null +++ b/gradle.properties @@ -0,0 +1,5 @@ +# No AndroidX today (core uses okhttp-jvm; app sources are framework-only, TM-005).
