From b940dd34f8dc1960a83bd3f5cbd0aeca6f403ec2 Mon Sep 17 00:00:00 2001 From: Shanu Date: Tue, 6 Oct 2026 11:51:42 +0530 Subject: [PATCH 01/48] Run task_live's hosted roles on the managed default model With TINYHUMANS_TOKEN and no model named, task_live planned, rescued and shaped on the gateway's agentic-v1 tier. That tier reasons for 25 to 45 seconds over a small rescue, and on a real one it ran past the module's 120-second rescue limit; planning alone took about 40 to 50 seconds of a BlazeDemo or Selenium run. The default is now openrouter/deepseek/deepseek-v4-flash, the managed default OpenHuman runs its own hosted work on, which answers the same rescue in 7 to 13 seconds. A model named through TINYCOMPUTER_PLANNER_MODEL, _RESCUE_MODEL or _OUTPUT_MODEL still wins. --- .env.example | 4 ++-- .../src/bin/task_live/main.rs | 21 +++++++++++-------- .../tinycomputer-examples/live-tasks.md | 6 +++--- 3 files changed, 17 insertions(+), 14 deletions(-) diff --git a/.env.example b/.env.example index 311a10db..0b9e32ac 100644 --- a/.env.example +++ b/.env.example @@ -65,8 +65,8 @@ TINYCOMPUTER_LAB_SELF_EMAIL= # TINYCOMPUTER_FIXTURE_URL=http://127.0.0.1:8000 # task_live: a Tiny Humans bearer (a session token, or an API key with the # `inference` scope) in place of OPENROUTER_API_KEY; Jev and the planner then -# go through Tiny Humans' routes, and the gateway's agentic-v1 plans, rescues, -# and shapes unless the model variables below name another. +# go through Tiny Humans' routes, and openrouter/deepseek/deepseek-v4-flash +# plans, rescues, and shapes unless the model variables below name another. # TINYHUMANS_TOKEN= # The planner model task_live asks for. # TINYCOMPUTER_PLANNER_MODEL= diff --git a/crates/tinycomputer-examples/src/bin/task_live/main.rs b/crates/tinycomputer-examples/src/bin/task_live/main.rs index 36287b5d..49fc29e1 100644 --- a/crates/tinycomputer-examples/src/bin/task_live/main.rs +++ b/crates/tinycomputer-examples/src/bin/task_live/main.rs @@ -15,8 +15,8 @@ //! - `TINYHUMANS_TOKEN` — optional, in place of `OPENROUTER_API_KEY`: a Tiny //!

Once a text has arrived, enter now looks again and, when rows appeared that were not on screen before it was typed, picks the one matching it: rows that mention the text first, a single match pressed without asking, otherwise Jev picks among at most 12 or answers that none fits. Without a mention, only new rows drawn as a list's rows are offered, so a button that appeared beside the box is never taken for a suggestion. A private text is never offered, and a field that opens no list asks nothing. The simulator gains a ride form whose boxes behave this way; the new test fails without the change with the pickup box emptied. --- crates/tinycomputer-bus/src/flow/guide.md | 2 +- .../src/agentic/flow/enter/fill.rs | 25 +++- .../src/agentic/flow/flow_tests.rs | 3 + .../src/agentic/flow/flow_tests/places.rs | 129 ++++++++++++++++++ .../src/agentic/flow/flow_tests/simulator.rs | 13 +- .../flow/flow_tests/suggestion_tests.rs | 116 ++++++++++++++++ .../src/agentic/flow/steps/mod.rs | 1 + .../src/agentic/flow/steps/suggestion.rs | 118 ++++++++++++++++ .../tinycomputer-engine/flow/filling-forms.md | 22 +++ .../tinycomputer-engine/flow/step-kinds.md | 4 +- 10 files changed, 422 insertions(+), 11 deletions(-) create mode 100644 crates/tinycomputer-engine/src/agentic/flow/flow_tests/places.rs create mode 100644 crates/tinycomputer-engine/src/agentic/flow/flow_tests/suggestion_tests.rs create mode 100644 crates/tinycomputer-engine/src/agentic/flow/steps/suggestion.rs diff --git a/crates/tinycomputer-bus/src/flow/guide.md b/crates/tinycomputer-bus/src/flow/guide.md index 2cb162b6..40eee112 100644 --- a/crates/tinycomputer-bus/src/flow/guide.md +++ b/crates/tinycomputer-bus/src/flow/guide.md @@ -37,7 +37,7 @@ do. | `open` | `{"open": "Mail"}` | Launch the app or bring it forward. | | `browse` | `{"browse": "https://www.google.com/travel/flights"}` | Open a web address in the browser; later steps act on the page until an `open` switches back to an app. | | `do` | `{"do": "start a new note"}` | Same as a plain string. | -| `enter` | `{"enter": {"subject": "Hi"}}` | Put each text into the field its key describes. | +| `enter` | `{"enter": {"subject": "Hi"}}` | Put each text into the field its key describes; a box that suggests matches as you type (a location, a city) has the matching suggestion picked. | | `choose` | `{"choose": {"what": "the font list", "option": "Helvetica"}}` | Pick an option in a list, menu, or popup. | | `read` | `{"read": {"what": "the newest message's subject", "into": "subject"}}` | Store visible text in a variable. | | `extract` | `{"extract": {"what": "the flight results", "into": "flights"}}` | Store every item of a list, as JSON rows of their text, in a variable. | diff --git a/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs b/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs index 13bc6222..e7ee5e1c 100644 --- a/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs +++ b/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs @@ -11,7 +11,7 @@ use crate::agentic::flow::{ AgentBackend, FlowRun, Halt, StepLog, backend::deliver_text, memory::{learn, remember}, - view::{Candidate, element_kind, label}, + view::{Candidate, Screen, element_kind, label}, }; use super::{BLIND_PICK_MISSES, REVEAL_TURNS, editable, names}; @@ -78,7 +78,13 @@ impl FlowRun<'_, B> { for assignment in assignments { let slot = &slots[assignment.slot]; let filled = self - .fill(log, slot, &assignment.field, &screen.context) + .fill( + log, + slot, + &assignment.field, + &screen, + private[assignment.slot], + ) .await?; if !filled { struck.insert(element_kind(&assignment.field)); @@ -134,21 +140,26 @@ impl FlowRun<'_, B> { /// Delivers one slot's text and reports whether it verifiably arrived. /// /// A date is typed in the layout the field or the page around it asks - /// for ("DD-MM-YYYY"), so an input mask does not mangle it. + /// for ("DD-MM-YYYY"), so an input mask does not mangle it.

The decision journal event gains `parts`, and its `request_bytes` is the largest part. --- .../src/agentic/flow/decide.rs | 130 ++++++++++++++--- .../src/agentic/flow/escalate/belief.rs | 15 +- .../src/agentic/flow/flow_tests.rs | 1 + .../agentic/flow/flow_tests/split_tests.rs | 131 ++++++++++++++++++ .../src/agentic/flow/mod.rs | 12 +- .../flow/budgets-and-switches.md | 2 +- .../flow/voting-and-briefing.md | 27 ++-- docs/technical/jev-harness.md | 10 +- docs/technical/jev-journal.md | 2 +- docs/technical/jev-questions.md | 3 +- 10 files changed, 289 insertions(+), 44 deletions(-) create mode 100644 crates/tinycomputer-engine/src/agentic/flow/flow_tests/split_tests.rs diff --git a/crates/tinycomputer-engine/src/agentic/flow/decide.rs b/crates/tinycomputer-engine/src/agentic/flow/decide.rs index f000a54e..c2234873 100644 --- a/crates/tinycomputer-engine/src/agentic/flow/decide.rs +++ b/crates/tinycomputer-engine/src/agentic/flow/decide.rs @@ -63,32 +63,46 @@ impl FlowRun<'_, B> { let batched = requests.len(); let mut asked = Vec::with_capacity(batched); for request in requests { - let request = self.outgoing(log, request); - let framings = vote::framings(&request, votes); - let handles = self.spawn(&framings); - asked.push((request, framings, handles)); + let parts = self.outgoing(log, request); + let framings = parts + .iter() + .map(|part| vote::framings(part, votes)) + .collect::>(); + let handles = framings + .iter() + .map(|framings| self.spawn(framings)) + .collect::>(); + asked.push((parts, framings, handles)); } self.rounds = self.rounds.saturating_add(1); let asked_at = Instant::now(); let mut replies = Vec::with_capacity(batched); - for (request, framings, handles) in asked { + for (parts, framings, handles) in asked { self.decisions = self.decisions.saturating_add(1); let mut answered = Vec::new(); let mut failure = None; - for (framing, handle) in framings.into_iter().zip(handles) { - match handle.await { - Ok(Ok(evaluation)) => { - merge_metrics(&mut self.metrics, &evaluation); - log.calls = log.calls.saturating_add(1); - answered.push((framing, evaluation.response.answers)); - } - Ok(Err(error)) => { - failure.get_or_insert(error); + // A part none of whose framings answered leaves its questions + // without an answer, which fails the decision as a whole. + let mut unanswered = false; + for (framings, handles) in framings.into_iter().zip(handles) { + let before = answered.len(); + for (framing, handle) in framings.into_iter().zip(handles) { + match handle.await { + Ok(Ok(evaluation)) => { + merge_metrics(&mut self.metrics, &evaluation); + log.calls = log.calls.saturating_add(1); + answered.push((framing, evaluation.response.answers)); + } + Ok(Err(error)) => { + failure.get_or_insert(error); + } + Err(_) => {} } - Err(_) => {} } + unanswered |= answered.len() == before; } - let answers = match (answered.is_empty(), failure) { + let request = whole(&parts); + let answers = match (unanswered, failure) { (true, Some(failure)) => return Err(Halt::Error(provider_error(&failure))), (true, None) => { return Err(Halt::Failed("no Jev evaluation completed".to_owned())); @@ -110,7 +124,8 @@ impl FlowRun<'_, B> { "framings": votes, "answered": answered.len(), "batched": batched, - "request_bytes": serde_json::to_vec(&request).map_or(0, |bytes| bytes.len()), + "parts": parts.len(), + "request_bytes": largest(&parts), "wall_ms": millis(asked_at.elapsed()), }) }); @@ -131,12 +146,13 @@ impl FlowRun<'_, B> { } /// `request` as it leaves for Jev: with the page-kind question on a web - /// page, briefed, masked, and fitted to size. + /// page, briefed, masked, and fitted to size, in parts when its + /// questions outgrow one request ([`split`]). pub(super) fn outgoing( &self, log: &mut StepLog, mut request: EvaluationRequest, - ) -> EvaluationRequest { + ) -> Vec { if self.enabled(FlowLoop::PageKind) && self.app == crate::workspace::BROWSER { log.used(FlowLoop::PageKind); request @@ -146,8 +162,13 @@ impl FlowRun<'_, B> { self.brief_into(&mut request); self.mask(&mut request); clip_masked_state(&mut request.state); - fit(&mut request, MAX_REQUEST_BYTES); - request + split(request, MAX_REQUEST_BYTES) + .into_iter() + .map(|mut part| { + fit(&mut part, MAX_REQUEST_BYTES); + part + }) + .collect() } /// Sends every framing to Jev at once. @@ -192,6 +213,73 @@ impl FlowRun<'_, B> { /// The id of the page-kind question a request on a web page carries. pub(super) const PAGE_KIND: &str = "page_kind"; +/// `request` cut by its questions into requests of at most `limit` bytes of +/// JSON, each carrying the whole state and as many of the questions, in +/// order, as fit beside it.

Live, three layouts slipped through: - a store's grid where every card is one link holding its picture, name, and price (and often its own add button), and a ride app's options, each one option control holding its fare. Runs of three or more same-role links, options, radios, or buttons under one parent, each showing 20 or more characters with a word, are now lists beside the ordinal ones, longest first; - a row of a card's image dots ("1", "2", "3"), and a card holding 22 of them, were taken for the products. A list whose every card shows only bare markers (three letters or digits a field) is not results; - a card that began with its pack-size dropdown was opened through it. A card's opener is now a control that says it opens or selects, then a named link (the product's title), and only then the first control.

Such a dialog is never cleared by attention, an obstacle dismissal, Escape, or an undo; while it is in front, controls it covers are not offered as moves, nor its close control unless the step says to close. A browser run's first look takes a dialog in front as the task's (a rescue's inheritance); an application's own opening alert is still cleared. - A step that fails in front of that dialog names its own controls, so a rescue answers with one of them: rescues kept choosing a language heading above a format dialog's buttons. - A control, or a key, pressed three times in a step is not pressed again (a toggle's open and closed looks count as one control). Once a named control is pressed, its copies on other items are struck off for the step unless it says all, every, each, or both: a step adding two packets of one milk pressed "Add" on six products. An undo lifts them. - Attention leaves a layer open when a control in front fits the step as well as anything behind it: a location dialog was escaped by the step that meant to press its "Use my current location". - "allow selection" and "save my choices" are consent-card closers. - The move option says a control scrolled out of view can be pressed; the judge called a step stuck rather than press one. - A step that stalls says its work may already be done, so a rescue skips a search button a live search does not have. --- .../src/agentic/flow/act/judge.rs | 2 +- .../src/agentic/flow/act/mod.rs | 36 +++- .../src/agentic/flow/act/moves.rs | 82 +++++++- .../src/agentic/flow/act/recover.rs | 19 +- .../src/agentic/flow/act/turns.rs | 182 ++++++++++++++++-- .../src/agentic/flow/action.rs | 5 + .../src/agentic/flow/attention/clear.rs | 7 +- .../src/agentic/flow/attention/find.rs | 34 +++- .../src/agentic/flow/front.rs | 158 +++++++++++++++ .../src/agentic/flow/look.rs | 4 + .../src/agentic/flow/mod.rs | 5 + .../src/agentic/flow/run.rs | 2 + .../src/agentic/flow/view/mod.rs | 18 ++ .../src/agentic/flow/wide/judge.rs | 7 +- 14 files changed, 519 insertions(+), 42 deletions(-) create mode 100644 crates/tinycomputer-engine/src/agentic/flow/front.rs diff --git a/crates/tinycomputer-engine/src/agentic/flow/act/judge.rs b/crates/tinycomputer-engine/src/agentic/flow/act/judge.rs index dec4e0ba..822c599e 100644 --- a/crates/tinycomputer-engine/src/agentic/flow/act/judge.rs +++ b/crates/tinycomputer-engine/src/agentic/flow/act/judge.rs @@ -163,7 +163,7 @@ impl FlowRun<'_, B> { if questions.is_empty() || !self.enabled(FlowLoop::Moves) { return self.judge(log, screen, intent, None).await; } - let pool = self.pool(screen, "Click", banned); + let pool = self.pool(screen, "Click", banned, intent); let opening = self.opening( log, screen, diff --git a/crates/tinycomputer-engine/src/agentic/flow/act/mod.rs b/crates/tinycomputer-engine/src/agentic/flow/act/mod.rs index 40048edd..cc4c2385 100644 --- a/crates/tinycomputer-engine/src/agentic/flow/act/mod.rs +++ b/crates/tinycomputer-engine/src/agentic/flow/act/mod.rs @@ -31,7 +31,10 @@ mod turns; pub(super) use judge::Judgement; -use std::{collections::BTreeSet, time::Instant}; +use std::{ + collections::{BTreeMap, BTreeSet}, + time::Instant, +}; use tinycomputer_bus::StepOutcome; @@ -61,6 +64,15 @@ const SHORTCUT_FLOOR: f64 = 0.5; const STALL_TURNS: u32 = 3; /// Waits in a row that changed nothing after which Jev is not let wait again. const MAX_IDLE_WAITS: u32 = 2; +/// Scrolls that showed nothing new after which a step's "scroll" is taken +/// as "activate": the screen already lists what lies below the fold, so a +/// step that keeps scrolling never acts (live, a movie list three times). +const MAX_IDLE_SCROLLS: u32 = 1; +/// Presses of one control in one step after which it is not pressed again. +/// A toggle pressed over and over keeps changing the screen, so the stall +/// guard never fires (live, a header button seven times in one step), while +/// a quantity stepper still goes up by three. +const MAX_REPEAT_PRESSES: u32 = 3; /// Obstacles dismissed per step at most. const MAX_OBSTACLES: u32 = 2; /// Undos per step at most. @@ -86,7 +98,9 @@ const CHANGES_VIEW: &str = const MOVES: &[(&str, &str)] = &[ ( "activate", - "Press one visible control: a button, link, tab, list row, toolbar item, or menu item.", + // Live, every control of a page scrolled down read as offscreen, + // and the judge called the step stuck rather than press one. + "Press one control: a button, link, tab, list row, toolbar item, or menu item.

A place box looks twice more for late suggestions, and there a row already showing counts when it matches, as does a pressable box sharing half the typed words. - A pick by "first " walks the list in page order for the first item that meets the condition: judged at once, it took the fifth. - wait_for holds on a settled screen judged at 0.65 or more three checks in a row; more "found nothing" phrases end it early. - A date option matches a strip's "WED 07 OCT": leading zeros, short months, and no year unless shown. - A read takes the text holding the value itself, the shortest. - The rescuer is told a delivering store finds nothing until its place is set, to keep the task's size and variant words, and never to stop before a login the task did not ask for. --- .../src/agentic/flow/enter/fill.rs | 186 ++++++++++++++++-- .../src/agentic/flow/enter/mod.rs | 9 + .../agentic/flow/flow_tests/choose_tests.rs | 18 ++ .../agentic/flow/flow_tests/enter_tests.rs | 8 +- .../src/agentic/flow/flow_tests/pick_tests.rs | 22 +++ .../flow/flow_tests/step_kinds_tests.rs | 39 ++++ .../flow/flow_tests/suggestion_tests.rs | 51 +++++ .../src/agentic/flow/steps/condition.rs | 38 +++- .../src/agentic/flow/steps/date.rs | 35 +++- .../src/agentic/flow/steps/list.rs | 43 +++- .../src/agentic/flow/steps/matching.rs | 6 +- .../src/agentic/flow/steps/mod.rs | 18 +- .../src/agentic/flow/steps/read.rs | 4 + .../src/agentic/flow/steps/suggestion.rs | 170 ++++++++++++++-- .../src/agentic/flow/steps/typing.rs | 97 +++++++++ crates/tinycomputer-engine/src/rescue/mod.rs | 14 +- 16 files changed, 703 insertions(+), 55 deletions(-) create mode 100644 crates/tinycomputer-engine/src/agentic/flow/steps/typing.rs diff --git a/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs b/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs index e7ee5e1c..893f0f99 100644 --- a/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs +++ b/crates/tinycomputer-engine/src/agentic/flow/enter/fill.rs @@ -4,19 +4,82 @@ use std::collections::BTreeSet; use serde_json::Value; -use tinycomputer_bus::Slot; +use tinycomputer_bus::{JevOperation, Slot}; use tinycomputer_core::reformat_date; use crate::agentic::flow::{ AgentBackend, FlowRun, Halt, StepLog, backend::deliver_text, memory::{learn, remember}, - view::{Candidate, Screen, element_kind, label}, + view::{Candidate, Screen, element_kind, is_destructive, label}, }; use super::{BLIND_PICK_MISSES, REVEAL_TURNS, editable, names}; impl FlowRun<'_, B> { + /// Presses the control on `screen` whose label holds a pending slot's + /// own word (`named_opener`); `true` when it did.
