feat(coordinator): the nudge bodies state observed facts, never hedges

Browse Source 
The idle-children header drops its opening idleness claim: a queued
entry delivers at whichever seam arrives next, and the drain
predicate re-verifies that children are active — never that the
coordinator is still idle — so the body now opens with the one fact
the delivery just verified.

The tasks body replaces its hedged children sentence with one
observed-fact line per child. The old sentence hedged states the
producer's read had just returned and invented activity for an idle
coordinator; the producer now threads (ws_id, state) pairs through,
and the formatter renders a running child as running (check before
redoing what it owns) and a stopped one as stopped, with the
tool-behaviour fact that wait_for_workstream returns immediately for
it. The line asserts nothing about results: no read observes whether
a child produced anything, and the immediate wait is the whole
protection — checking is cheap and finds whatever is there. Fact
lines are formatter-built beside the counts opener, so no tail
override can reach them; the formatter's old indeterminate-read hedge
branch is deleted (a failed read renders no body at all), and the
open-row status takes the same alteration check as the id.

Both bodies hand the model full workstream ids: the resolver refuses
truncated ids by design, so the roster's 8-char prefixes were not
handles — a model copying a bullet issued a call the resolver
rejects. Display prefixing stays on the operator card, derived from
the full id in the metadata.

Eval alignment: fixture child ids become production-shaped 32-hex (a
prefix looked like a different id entirely and the old shape only
resolved through the legacy branch); a body-override sweep refuses
cells without a live child at config time, keyed on the formatter's
own childless condition, so candidate text can never be measured over
a world production cannot produce.

*child_ws_ids* is keyword-only and required, and it is the SINGLE
value governing every children-bearing element of this body — the
caveat sentence, the blocked-on-a-child branch, and that branch's two
slots. One value because one storage read answers all of them, and
because a body that omits the sentence about children while keeping
the instruction about children is a contradiction the reader has to
resolve. The trichotomy is exactly the one the caller's read
produces:
*children* is keyword-only and REQUIRED — a list of
``(ws_id, state)`` pairs, the exact projection both callers hold
(the observer's ``_live_children_for_body`` over live-state rows and
the eval's ``_body_children`` over fixture rows) — and it is the
SINGLE value governing every children-bearing element of this body:
the per-child fact lines, the blocked-on-a-child branch, and that
branch's two slots. One value because one storage read answers all
of them, and because a body that renders facts about children while
omitting the instruction about them (or the reverse) is a
contradiction the reader has to resolve. Two states, exactly the
two the caller's read produces:
* ``[]`` — an affirmative "this coordinator has no child row in a
live state" — removes :data:`NUDGE_IDLE_TASKS_CHILDREN_CAVEAT` AND
:data:`NUDGE_IDLE_TASKS_CHILD_DOOR`, both by literal match rather
than by position, so a reworded neighbour cannot shift either cut.
Nothing about children survives: no sentence, no branch, no
live state" — renders no fact lines and removes
:data:`NUDGE_IDLE_TASKS_CHILD_DOOR` by literal match rather than
by position, so a reworded neighbour cannot shift the cut.
Nothing about children survives: no facts, no branch, no
placeholder pointing at a lookup that is known to return nothing.
* a NON-EMPTY list keeps both and populates the branch: the wait call
takes every id (capped at :data:`NUDGE_IDLE_CHILDREN_WAIT_CAP`,
``mode="any"``), which is unambiguous because a list slot has no
wrong element to pick, and ``child_ws_id`` takes the first — most
recently updated, since the caller's query orders by
``updated DESC``.
* ``None`` — "I am not asserting a children state" — keeps both and
substitutes neither slot. PRODUCTION NEVER PASSES THIS. The
observer used to, for an indeterminate read, and now fails its
whole event closed instead — a failed storage read silences BOTH
idle nudges before either cap is charged: a nudge fired off a
query that just failed is a reminder we cannot substantiate,
aimed at a backend that is telling us it is unwell. Not sending
is as safe as hedging and strictly cheaper, so the hedge lost its
reason.
* a NON-EMPTY list renders ONE FACT LINE PER CHILD under the counts
line and populates the branch. Each line states the observed
fact and nothing more — the states are the caller's read, taken
this same event, so hedging them would be manufactured
uncertainty:
The branch stays because it has a live caller:
``turnstone.eval.nudges.render_tasks_body`` passes it under
``--body-override``, where the tail is operator-authored candidate
text and BOTH literal cuts must be suppressed so a candidate that
quotes the shipped caveat verbatim is not silently mauled. ``None``
is the only input that says "cut nothing" without also inventing a
ws_id to substitute. If that caller ever goes, so should this
branch — it is not kept for safety.
- a child whose state is outside
:data:`NUDGE_CHILD_STOPPED_STATES` (thinking / running /
attention today) is STILL RUNNING; the line says so and carries
the check-before-redoing protection.
- a child in :data:`NUDGE_CHILD_STOPPED_STATES` (idle / error)
has STOPPED, and the line carries the wait-returns-immediately
point, true for exactly those states (they are the wait's live
terminal states). It asserts NOTHING about results: "may hold
uncollected results" was cut as a fabrication (2026-07-29) —
"results" is a noun the read never observed, and "uncollected"
implies a collection ledger nobody consulted; hedging an entity
into existence with "may" is still fabrication. The immediate
wait is the whole protection: checking is cheap, and whatever
the child did or did not produce is what the check finds.
Populating the child slots asserts nothing about the TASK: it fills
the only values a call there could take. Whether any item is in
fact waiting on a child stays the model's judgement, which is why
the branch is still a conditional sentence.
The branch's wait call takes every id (capped at
:data:`NUDGE_IDLE_CHILDREN_WAIT_CAP`, ``mode="any"``), which is
unambiguous because a list slot has no wrong element to pick, and
``child_ws_id`` takes the first — most recently updated, since
the caller's query orders by ``updated DESC``.
NO SANITISER runs on the counts, the statuses or the ws_ids: the
counts are integers, the statuses are the producer's own
``TASK_OPEN_STATUSES`` vocabulary, and the ws_ids come from the
workstreams table's primary key — the same server-minted source
:func:`format_idle_children_nudge` already interpolates raw into its
wait call, so a stricter rule here would be an asymmetry with no
reason behind it. Task ids take the sanitiser as an
ALTERATION CHECK (above) because their store is softer.
BELT-AND-BRACES RULE (the :func:`format_idle_children_nudge`
precedent): any model- or user-authored field this body ever grows
MUST go back through :func:`sanitize_name` before interpolation —
server-minted provenance is the only exemption.
``None`` is NOT an input any more. The old "I am not asserting a
children state" hedge branch lost production when the observer began
failing its whole event closed on an indeterminate read, and lost
its last caller (the eval override's cut-nothing mapping) when the
override sweep started refusing childless cells at config time — so
it died with the rule its own docstring predicted it would. A
failed read renders no body at all; there is nothing left for a
hedge to cover.
Fact lines and slot population assert nothing about the TASKS: they
state each child's observed state and fill the only values a call
there could take. Whether any item is in fact waiting on a child
stays the model's judgement, which is why the branch is still a
conditional sentence. Ids render FULL — the resolver refuses
truncated ids by design, and a fact line's purpose is to pair a
usable handle with the fact about it.
NO SANITISER runs on the counts line or the children values: the
counts are integers, the counts line's status terms are the
producer's own mapping over ``TASK_OPEN_STATUSES`` (never row data),
and the child ws_ids and states come from the workstreams table's
primary key and the state enum — the same server-minted sources
:func:`format_idle_children_nudge` already interpolates raw, so a
stricter rule here would be an asymmetry with no reason behind it.
The open-row fields — id AND status — take the sanitiser as an
ALTERATION CHECK (above) because their store, the task envelope
blob, is softer. BELT-AND-BRACES RULE (the
:func:`format_idle_children_nudge` precedent): any model- or
user-authored field this body ever grows MUST go back through
:func:`sanitize_name` before interpolation — server-minted
provenance is the only exemption.
COMPOSITION CAVEAT, carried where the next editor will see it:
counts-without-provenance was never measured as a single body —
the counts candidate and the provenance ablation each measured

*override_active* says a ``--body-override`` candidate is installed
in ``NUDGE_IDLE_TASKS_TAIL``. It forces the caveat branch ON, for
every arm and every cell: the conditional's removal is anchored to
the SHIPPED sentence, and the likeliest candidate wording of all —
one that keeps that sentence verbatim while editing a different
paragraph — still contains the literal, so the cut would land and a
childless cell would silently measure a candidate nobody wrote. An
override measures candidate text exactly as authored.
It suppresses BOTH literal cuts by mapping an empty list to ``None``
rather than by inventing a child: ``None`` is the one input that says
"cut nothing" without also substituting a ws_id, so the protection
stays exactly as wide as it was when this argument was a bool and
cannot smuggle a fabricated id into a measured stimulus. A cell that
HAS children keeps its real ids under an override, because that is
what its runs would really receive.
THIS IS THE SOLE REMAINING CALLER of the formatter's ``None`` branch.
Production stopped producing it when the observer began declining to
fire on an indeterminate children read, so the branch is alive on
this line and nowhere else — if this rule is ever dropped, the
formatter's ``None`` handling should go with it rather than linger as
scaffolding.
No override handling lives here any more. The formatter's one
literal cut (the childless branch removing the door) can only run
against candidate text from a childless cell state, and the sweep
refuses those at config time under ``--body-override``
(:func:`_check_override_cells_have_a_live_child`); the arm that IS
the childless branch is skipped there
(:data:`_OVERRIDE_SKIPPED_ARMS`). A cell WITH children keeps its
real rows under an override, because that is what its runs would
really receive — and the ``None`` "cut nothing" input this
function's override rule used to feed died with its last caller,

opener and the children fact lines are formatter-built from seeded

is a childless world to the formatter — the raw-list reading would
wave it through and the maul would land anyway. Same derivation
