Subject: [PATCH 1/5] feat(goal): carry budget figures and progress guidance in
 the continuation prompt

The continuation prompt told the model what the objective was and how to
deliver it, and nothing about two things it had no other cheap way to know.

It could not see how much of the spend window was left. A Goal stops when
`tokensUsed` reaches `tokenBudget`, 30,000,000 by default, and gets one
wind-down turn to hand off; until that turn arrives there was no signal at
all, so the model could not tell turn 3 of a long run from the turn before the
budget stops it, and could not choose between opening a broad investigation
and finishing what it had. `get_goal` does not carry the figures either, so
there was not even an expensive way to ask.

It was also never asked whether its last turn accomplished anything. The
verifier only ever sees a terminal proposal, so a turn that proposes nothing is
judged by nobody -- and a turn spent restating status is exactly the turn that
proposes nothing.

Each runtime-scheduled turn now opens with what has been spent, out of what,
what remains, and how many turns are behind it, followed by four standing
lines: treat the workspace rather than the conversation as authoritative; work
toward the end state the objective asks for rather than a more easily reached
one; judge whether the previous turn actually changed anything before spending
this one; and check every requirement against citable evidence before
proposing completion.

The figures sit after the standing objective guard and before the
objective-updated notice, which is about what changed since the last turn and
so reads last. They stay out of the data block on purpose: that block is
compared by content to decide whether the objective changed, and a number that
moves every turn would make every turn look like an edit. The remainder is
clamped at zero, since the hand-off turn runs with the window already
overspent.

The progress lines are skipped on that hand-off turn, which is told not to
start new work -- a line asking for "a different concrete action now" would
contradict it. The budget line stays, because a hand-off reports the numbers it
stopped at.

`usage` is optional on the host contract, so a host with no figures renders
exactly the prompt it did before. The three hosts copy it through their queue
entries alongside the fields they already copy.

+# Telling the model what its Goal has spent, and asking it to check its own progress
+
+## Problem
+
+The continuation prompt is four shared lines, a synthetic-turn guard, the data
+block, and the standing objective guard. It tells the model what the objective
+is and how to deliver it. It says nothing about two things the model has no
+other cheap way to know.
+
+**How much of the window is left.** A Goal stops when `tokensUsed` reaches
+`tokenBudget`, 30,000,000 by default, and gets one wind-down turn to hand off.
+Until that turn arrives the model has no signal at all: it cannot tell turn 3
+of a long run from the turn before the budget stops it, so it cannot choose
+between starting a broad investigation and finishing what it has. `get_goal`
+does not carry the figures either, so there is not even an expensive way to
+ask.
+
+**Whether the last turn accomplished anything.** The verifier only ever sees a
+terminal proposal. A turn that proposes nothing is judged by nobody -- and a
+turn spent restating status is exactly the turn that proposes nothing. Nothing
+in the prompt asks the model to notice that its previous turn changed nothing
+and to do something different.
+
+Codex's continuation template runs to 56 lines and covers both: a budget block
+with the same figures, plus work-from-evidence, no-progress, fidelity, and
+completion-audit sections. Claude Code has no equivalent; its Stop hook feeds
+back a refusal reason instead.
+
+## Design
+
+Two additions to the one place every host renders from.
+
+**A budget line**, when the runtime supplies figures: what has been spent, out
+of what, how much remains, and how many turns are behind it. Spelled out with
+locale grouping rather than abbreviated, since a prompt is read once by a
+model and not squeezed into a footer.
+
+It sits after the standing objective guard and before the objective-updated
+notice. The figures are context for the whole turn; the notice is about what
+changed since the last one and reads last so it is acted on last.
+
+It stays out of the data block deliberately. That block is untrusted task data,
+and `announcedObjective` compares it by content to decide whether the objective
+changed -- a number that moves every turn would make every turn look like an
+edit.
+
+The remainder is clamped at zero. The wind-down turn runs with the window
+already overspent, and a negative remainder would read as nonsense on the one
+turn the figures matter most.
+
+**Four progress lines**, on every turn except the hand-off. They ask the model
+to treat the workspace rather than the conversation as authoritative, to work
+toward the end state the objective asks for rather than a more easily reached
+one, to judge whether its previous turn actually changed anything before
+spending this one, and to check every explicit requirement against citable
+evidence before proposing completion.
+
+They are skipped on the wind-down turn, which is told not to start new work: a
+line asking for "a different concrete action now" would contradict it. The
+budget line is kept there, because a hand-off reports the numbers it stopped
+at.
+
+**Where the figures come from.** `GoalTurnHost.startGoalTurn` gains an optional
+`usage`, and `flushContinuation` reads it off the record at scheduling time,
+before the broadcast hands listeners a snapshot they may act on. The three
+hosts copy it into their queue entries alongside the fields they already copy,
+and pass it to the renderer. User-driven turns never render this prompt, so
+they never carry figures.
+
+`usage` is optional rather than required so that a host with no figures, and
+every test written before them, renders exactly the prompt it did before.
+
+## Scope
+
+- `goal-continuation-prompt.ts`: the `usage` input, `renderBudgetLine`,
+  `PROGRESS_LINES`, their placement, and the `buildGoalContinuationParts`
+  pass-through.
+- `goal-runtime.ts`: the `usage` field on the host contract, and reading it off
+  the record in `flushContinuation`.
+- `useMessageQueue.ts` and `use-llm-stream.ts`, `Session.ts`,
+  `nonInteractiveCli.ts`: one field copied through each host's queue entry.
+- `docs/users/features/goals.md`: what each continuation turn now tells the
+  model.
+
+Not changed: the `get_goal` and `update_goal` tool descriptions; the blocked
+audit, which qwen already runs as a three-turn fingerprint check in the
+runtime rather than as prompt text; and the runtime's own bounds, which are
+separate work.
+
+## Verification
+
+- `goal-continuation-prompt.test.ts`: the five expectations that pin the whole
+  prompt carry the new lines; the budget line is pinned for the with-budget,
+  no-budget, and overspent cases; its position above the objective-updated
+  notice is pinned; a host with no figures renders no budget line; the
+  wind-down turn carries the budget line and not the progress lines.
+- `goal-runtime.test.ts`: the host receives the figures the record held when
+  the turn was scheduled, before and after a turn bills; a Goal with no ceiling
+  reports none; the wind-down hand-off carries them too.
+- `.qwen/e2e-tests/2026-09-07-goal-continuation-budget.md`: the rendered prompt
+  read out of a real session transcript.

 Creating, editing, or resuming a Goal requires a trusted workspace (`/trust`). Headless usage is covered in [Headless Mode](./headless.md#run-a-persistent-goal).
 
+Each turn the session takes on its own begins with what the Goal has spent so far, the window it is allowed, and how many turns are behind it, so the model can tell an early turn from the last one before the budget stops it. Those turns also carry standing instructions to re-check the workspace rather than trust earlier turns' reports, to work toward the end state the objective asks for, to do something different when the previous turn changed nothing, and to check every requirement against citable evidence before proposing that the Goal is done.

 ## Interrupting a Goal
 
 Cancelling a Goal turn pauses the Goal. Press Esc while the model is answering or while its tools are still running, and the turn stops, the Goal moves to `paused`, and the card and `/goal` both say why it stopped. Nothing continues until you run `/goal resume`.

Subject: [PATCH 2/5] test(goal): pin the budget figures through each host, and
 skip the judgement on turn one

The three host copies were the only link in the chain with nothing behind
them: `usage` is optional on both sides of every hop, so deleting a copy
typechecks and costs the prompt its budget line on that host alone. One
case per host now fails when its copy is removed.

The judge-your-previous-turn line is held back on the Goal's first turn.
`create` schedules a continuation before any turn has finished, so that
line asks the model to judge a turn that does not exist. A host that
reports no figures still gets the line: not knowing the turn number is
not evidence of a first turn.

-# Telling the model what its Goal has spent, and asking it to check its own progress
-
-## Problem
-
-The continuation prompt is four shared lines, a synthetic-turn guard, the data
-block, and the standing objective guard. It tells the model what the objective
-is and how to deliver it. It says nothing about two things the model has no
-other cheap way to know.
-
-**How much of the window is left.** A Goal stops when `tokensUsed` reaches
-`tokenBudget`, 30,000,000 by default, and gets one wind-down turn to hand off.
-Until that turn arrives the model has no signal at all: it cannot tell turn 3
-of a long run from the turn before the budget stops it, so it cannot choose
-between starting a broad investigation and finishing what it has. `get_goal`
-does not carry the figures either, so there is not even an expensive way to
-ask.
-
-**Whether the last turn accomplished anything.** The verifier only ever sees a
-terminal proposal. A turn that proposes nothing is judged by nobody -- and a
-turn spent restating status is exactly the turn that proposes nothing. Nothing
-in the prompt asks the model to notice that its previous turn changed nothing
-and to do something different.
-
-Codex's continuation template runs to 56 lines and covers both: a budget block
-with the same figures, plus work-from-evidence, no-progress, fidelity, and
-completion-audit sections. Claude Code has no equivalent; its Stop hook feeds
-back a refusal reason instead.
-
-## Design
-
-Two additions to the one place every host renders from.
-
-**A budget line**, when the runtime supplies figures: what has been spent, out
-of what, how much remains, and how many turns are behind it. Spelled out with
-locale grouping rather than abbreviated, since a prompt is read once by a
-model and not squeezed into a footer.
-
-It sits after the standing objective guard and before the objective-updated
-notice. The figures are context for the whole turn; the notice is about what
-changed since the last one and reads last so it is acted on last.
-
-It stays out of the data block deliberately. That block is untrusted task data,
-and `announcedObjective` compares it by content to decide whether the objective
-changed -- a number that moves every turn would make every turn look like an
-edit.
-
-The remainder is clamped at zero. The wind-down turn runs with the window
-already overspent, and a negative remainder would read as nonsense on the one
-turn the figures matter most.
-
-**Four progress lines**, on every turn except the hand-off. They ask the model
-to treat the workspace rather than the conversation as authoritative, to work
-toward the end state the objective asks for rather than a more easily reached
-one, to judge whether its previous turn actually changed anything before
-spending this one, and to check every explicit requirement against citable
-evidence before proposing completion.
-
-They are skipped on the wind-down turn, which is told not to start new work: a
-line asking for "a different concrete action now" would contradict it. The
-budget line is kept there, because a hand-off reports the numbers it stopped
-at.
-
-The judge-your-previous-turn line is also held back on the Goal's first turn.
-`create` schedules a continuation before any Goal turn has finished, so on
-that one turn there is no previous turn to judge, and asking for the judgement
-invites the model to describe one. A host that reports no figures at all says
-nothing about which turn this is, so the line stands there: silence is not
-evidence of a first turn.
-
-**Where the figures come from.** `GoalTurnHost.startGoalTurn` gains an optional
-`usage`, and `flushContinuation` reads it off the record at scheduling time,
-before the broadcast hands listeners a snapshot they may act on. The three
-hosts copy it into their queue entries alongside the fields they already copy,
-and pass it to the renderer. User-driven turns never render this prompt, so
-they never carry figures.
-
-`usage` is optional rather than required so that a host with no figures, and
-every test written before them, renders exactly the prompt it did before.
-
-## Scope
-
-- `goal-continuation-prompt.ts`: the `usage` input, `renderBudgetLine`, the
-  four progress lines, their placement and their two exceptions, and the
-  `buildGoalContinuationParts` pass-through.
-- `goal-runtime.ts`: the `usage` field on the host contract, and reading it off
-  the record in `flushContinuation`.
-- `useMessageQueue.ts` and `use-llm-stream.ts`, `Session.ts`,
-  `nonInteractiveCli.ts`: one field copied through each host's queue entry.
-- `docs/users/features/goals.md`: what each continuation turn now tells the
-  model.
-
-Not changed: the `get_goal` and `update_goal` tool descriptions; the blocked
-audit, which qwen already runs as a three-turn fingerprint check in the
-runtime rather than as prompt text; and the runtime's own bounds, which are
-separate work.
-
-## Verification
-
-- `goal-continuation-prompt.test.ts`: the five expectations that pin the whole
-  prompt carry the new lines; the budget line is pinned for the with-budget,
-  no-budget, and overspent cases; its position above the objective-updated
-  notice is pinned; a host with no figures renders no budget line; the
-  wind-down turn carries the budget line and not the progress lines; the first
-  turn carries the other three progress lines but not the judgement one, and a
-  turn after it carries all four.
-- `useMessageQueue.test.ts`, `use-llm-stream.test.tsx`, `Session.test.ts`,
-  `nonInteractiveCli.test.ts`: one case per host, pinning that the figures
-  survive that host's copy. The field is optional on both sides of every hop,
-  so a dropped copy typechecks and would cost the budget line on that host
-  alone; each case fails when its copy is removed.
-- `goal-runtime.test.ts`: the host receives the figures the record held when
-  the turn was scheduled, before and after a turn bills; a Goal with no ceiling
-  reports none; the wind-down hand-off carries them too.
-- End to end against a real model: the rendered prompt read out of a session
-  transcript, in this change's pull request under Evidence.

+the runtime and renderer cannot drift into different shapes. The three hosts
+copy it into their queue entries alongside the fields they already copy, and
+pass it to the renderer. User-driven turns never render this prompt, so they
+never carry figures.
+
+`usage` remains optional on the public host and renderer contracts for
+embedders that have no runtime figures. Its absence omits only the token-budget
+line; the progress guidance still renders on non-wind-down turns.

 Once a Goal has billed a turn, the footer pill and every status card show what it has spent against the window it is allowed, as `1.2k/30.0m`. The figure counts the model calls the Goal makes in its own turns; subagents and the verifier's own checks are not included. The window is set by [`model.goalTokenBudget`](../configuration/settings.md); resuming a Goal that has spent its window grants another one on top of what it has already spent, so the figure reads `30.0m/60.0m` rather than starting over. A Goal with no budget shows only what it has spent. A Goal that has not billed a turn yet shows no figures at all.

+Each turn the session takes on its own reports what the Goal has spent so far, how many turns are behind it, and — unless the Goal runs unbounded — the window it is allowed. Every such turn except the final wind-down hand-off also carries standing instructions to re-check the workspace rather than trust earlier turns' reports, to work toward the end state the objective asks for, to do something different when the previous turn changed nothing (from the second turn on, once there is a previous turn to judge), and to check every requirement against citable evidence before proposing that the Goal is done.
