Build's and Edit's re_fix branches (handle_review's continue_adjusting,
handle_reverted's retry_after_revert) reset repair_attempts and
last_repair_error but not unknown_outcome_count. After the cap (count=2)
-> keep_draft -> review -> re_fix, the new cycle's FIRST unknown outcome
re-capped with "couldn't be determined twice in a row". Reset it at all
four sites, as Fix's re_fix already does.
Also pins that Edit's unknown-outcome cap drops a stale diagnosis and
staged repair (seeded, so the assertion is not vacuous).

apply_repair's preflight raises PreflightError when the graph it is about
to write would fail at Graph.init. Every handler caught it as a plain
ValueError, so the five apply sites could not tell it apart from a
graph_ops rejection:
- plan approval (Build, Edit) called ANY ValueError "The workflow can't
start", including "node not found: x", sending the user hunting for a
broken node that does not exist;
- the repair-apply gates (Build/Edit await_repair, Fix apply) called a
preflight rejection "The proposed fix no longer applies to the current
draft" -- the fix applied fine; it would leave an unstartable draft.
Add core DraftWouldNotStartError(ValueError) and make PreflightError
subclass it (services imports core; core still imports no services).
Each site now catches it before the ValueError branch, with the same
control flow and the true reason: plan approval keeps "The workflow
can't start" for it and says "Couldn't apply the workflow" otherwise;
the repair gates say "The workflow can't start" for it and keep
"Couldn't apply the fix" otherwise. The shared card/turn construction is
factored (_graph_not_applied, _change_not_applied, and
drop_unapplied_repair in handlers_fix) and the new literals are
catalogued in strings.py.

Build resets the breaker counter when the user re-enters the repair
loop from review or after a revert; Edit's equivalent branches did not,
so a count left over from an earlier cycle could trip the breaker one
round early.

Edit's affected-path test diagnosed and staged a repair for the same
engine failure with no counter at all, so the loop 6877532f8e closed for
Build stayed open for Edit. The breaker (engine-keyed signature,
consecutive-repeat counter, MAX_REPEATED_REPAIRS) moves to handlers_fix
under public names, Build keeps its underscore names as aliases, and
Edit stops at its gate on the third identical failure. A new edit goal
resets the counter.

Fix's re_fix action resets the rest of the repair loop's state but kept
unknown_outcome_count, so after the cap tripped the first unknown
outcome of the new repair cycle re-capped immediately instead of being
re-runnable once.

The unknown-outcome branch (a stream that ended with neither a terminal
nor an error frame) returned the user to the re-run state with no
limit in all three flows. With error frames now reported as failures
that branch is rare, but a stream that keeps ending early could still be
re-run forever. DifyBuilderContext.unknown_outcome_count counts
consecutive unknown outcomes (reset by any determinate one); the second
in a row stops at the gate with a card telling the user to look at the
run itself.

The first cut flagged any succeeded run where a branch node ran and no
End did, which also caught a legitimate side-effect-only arm that ran
to completion, and treated any fail-branch node as a router. The rule
is now the ESQ1-303 mechanism itself: a branch node ran and none of its
edge targets ran (the engine skipped every arm), in a graph that has an
End that was never reached. The card points at that branch node.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
ESQ1-303: both edges of a Builder-made if-else used handles the node
does not declare, so the engine skipped both arms, reached no End node,
and reported "succeeded" with outputs={}. Every verify handler took any
"succeeded" as "All checks passed".
A succeeded run that executed a branch node (if-else, question-
classifier, human-input, or a fail-branch node) and no End node is now
"Finished without output": an error-toned test card plus a card pointing
at the branch node, waiting at the gate with no staged repair -- the
engine reported no error, so there is nothing to diagnose. The rule is
deliberately that narrow: requiring an End node for every succeeded run
would false-fail side-effect-only branches, which the structural
validator does not forbid.

apply_repair streams a canvas marker per applied intent before its
preflight runs, so a rejected build left the client with markers for
mutations that were never written. The plan-approval catch now emits
revert_checkpoint: nothing was written and the draft is still the
checkpoint taken at approval.

apply_repair now rejects a graph Graph.init would refuse (PreflightError).
Build's and Edit's plan approval called apply_repair with no guard, so
the rejection would have escaped the handler and left the operation
interrupted mid-step. Both now catch it: the step is marked failed, an
error card names the node and the reason, nothing has been written, and
the plan stays at its gate -- re-approving regenerates the graph.

run_draft populates Run.error, and all three consumers threw it away:
Build and Edit assigned run_error = "" and Fix's Run(...) literal had no
error= at all. A launch failure therefore persisted with an empty error
(the long-open "TRUNCATED_STREAM_ERROR not persisted, err_len=0" item),
diagnose saw nothing, and the repair breaker -- which keys a launch
failure on run.error -- could never fire on one.
Fix's handle_verify also gains the try/except Build and Edit already
have, so a run_draft that raises degrades to a failed Run carrying the
launch error instead of killing the advance.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The streaming pipeline reports a run that threw as one ``event: error``
frame with top-level message/code and no data (ESQ1-302: Graph.init
rejected a node before workflow_started, so there is no run id either).
run_mapping had no representation for it: _TERMINAL_STREAM_EVENTS lists
only workflow_finished/paused, so the frame was neither terminal nor a
node event and the run came back "running" with the truncated-stream
notice.
error_from_stream_chunk reads such a frame; map_error_frame_run turns it
into a FAILED Run carrying the message (whitespace collapsed, so it is a
stable repair-breaker signature) and the code. map_run_result now keeps
the engine's run-level error text for a failed run instead of dropping
it -- a launch failure has no per-node rows, so that text is the only
evidence diagnose and the breaker have.

Run workflow streaming inside the Builder worker to avoid queue deadlocks. Forward native events to shared editor callbacks and wait for graph refresh before retesting repairs.
Keep command cleanup stable, preserve batched canvas events, and allow failed or unfinished historical runs to refresh again.
Starting a NEW Build session on an app whose draft already holds a previous
build's graph silently changed nothing and still reported "graph built".
_already_present matches a create_node by node id ALONE, and the generator
always emits node1, node2, ... So a new plan whose node2 is a
parameter-extractor was filtered out against an existing node2 that is an
llm: to_apply became empty, apply_repair([]) no-oped, change_set fell back
to "graph built", and the session advanced to build.execution over an
untouched canvas. Observed live -- the snapshot taken before apply was
byte-identical to the draft after it, and the subsequent test run "passed"
because it ran the OLD graph.
The id filter itself is deliberate and stays: it is what makes a loop-back
re-approve (continue_adjusting / revert) idempotent instead of raising on a
colliding id. The guard therefore keys on built_node_ids, which names what
THIS session built -- empty only on a session's first build, which is
exactly the broken case. A loop-back still no-ops silently and advances.
Does NOT clear the canvas on the user's behalf: that would destroy an
existing workflow. It reports honestly and stays in plan_approval.

_repair_is_repeating could never fire in production. _note_repair_error
counted repeats by exact string equality on diagnosis.root_cause, which is
LLM prose regenerated on every diagnosis call. Observed live across four
turns of one session: same failure, reworded every time, one turn switching
to Chinese. Equality therefore never held, repair_attempts reset forever,
and the guard was unreachable -- that session burned 9 failed verify runs
and 8 repair approvals with the guard in place.
The call site's own comment reads "ESQ1-285 burned nine approvals this way,
ESQ1-290 six". The reproduction burned nine again.
Key on the ENGINE's output instead: _failure_signature(run) returns the
first failed node's id plus its error text (whitespace-collapsed), falling
back to the launch error, and "" when the run identifies nothing -- so two
unknown failures never compare equal.
Why the existing tests passed while production was broken: every one of them
fed _note_repair_error the SAME literal string twice, and StubAgent.diagnose
always returns one fixed root_cause. They encoded the premise that is false
in production. The new handler-level test drives three turns with an agent
that rewords its root_cause each call while the engine fails identically,
and fails against the old implementation with repair_attempts == 0.
last_repair_error now holds that signature rather than prose. It was never
displayed -- its only use was this comparison.

Four findings from the whole-branch review, all in the repair loop:
I1 -- repair_attempts/last_repair_error were added to the context and to
serde but not to recovery._reset_working_fields (which clears eleven sibling
fields) nor to the re_fix/restart re-plan branches, so a fresh build could
inherit repair_attempts >= the ceiling and decline a repair on its FIRST
failure. They are cleared with their siblings now. The guard also ANDed a
monotonic counter with a consecutive-error test, so A -> B -> B tripped it
although B had survived one repair. _note_repair_error now makes the counter
mean what the docstring says: consecutive repeats of ONE error, reset when
the error changes.
I2 -- the repeated-failure return dropped run/run_id_sink, so repo.save_run
never ran while fc.verify_run_id already pointed at that run: a dangling
pointer and the third failing run lost from the debug export.
I3 -- ESQ1-291's empty-staged-repair guard existed in Build only. Edit's
model-config branch GUARANTEES an empty staged repair and routes to a state
whose approve applied it blindly; handlers_fix.handle_apply had the same
shape. Both are guarded now, reusing Build's notice.
I5 -- apply_repair re-validates intents against the draft as it is NOW, so a
dotted path that was applicable at propose time can raise ValueError at
approve time. Uncaught at all three approve sites, it reached the runner and
drove the session to FAILED -- the exact ESQ1-271 outcome this branch set out
to remove. Each site now degrades to a "Couldn't apply the fix" error card
naming the reason and clears the staged repair (engaging the I3 guard).
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
handle_await_repair offered "Apply the fix" unconditionally, so an empty
staged_repair produced approve -> apply nothing -> retest -> same failure
-> offer again, with no LLM in the loop. ESQ1-291's trace shows five such
approvals, every change set {count: 0, changes: []}.
Adds repair_attempts / last_repair_error to the context (both defaulted,
so persisted contexts deserialize unchanged) and _repair_is_repeating for
the follow-on gate. An empty staged repair is now declined with a decision
the user can act on instead of a run that cannot help.
_repair_is_repeating is also wired in at the point a repair is OFFERED
(the config-failure path in handle_test_and_repair, right after
diagnose()): a third identical failure clears staged_repair and surfaces
a "Repeated failure" card instead of proposing a fourth repair
(ESQ1-285/290 burned nine and six approvals this way).
Also catalogs the two new user-facing literals in core/dify_builder/
strings.py so test_catalog_covers_handler_literals keeps passing.

An LLM-supplied int node_id reached diff_graphs, which drops falsy and
non-string ids from its node maps, so result.changes came back empty and
build_change_set's fallback joined a list containing an int. The
TypeError took the whole session to `failed` (ESQ1-271) after the
mutation had already been committed to the draft.
validate_intent_args now rejects a non-string or empty node id, so
filter_applicable turns it into a rejection reason the agent can act on.
build_change_set str()s defensively -- that join must never be what kills
a session.
Also extends the same guard to set_node_config's `path` arg: a non-string
path used to reach _resolve_path's str.split() and raise AttributeError,
surfacing "'int' object has no attribute 'split'" to the repair agent
instead of an actionable rejection reason. Same boundary, same defect
shape, deliberately included here rather than deferred.

Mocking the inputs removed the work of inventing test data, but it also
removed the user's sight of what was actually tested. A green check
produced by {"topic": "test"} is weak evidence about a workflow, and an
invisible mock is a quieter version of the same false confidence a
passing-but-unverified test gives.
So keep the gate and pre-fill it: the form arrives with the mocked values
already in it, unfrozen, so the common case is one click rather than N
fields to type, and anyone who cares can edit before running. The cost
item 5 removed was PRODUCING the data, not confirming it.
Upload fields stay empty and still ask, because nothing can mock a file --
and the mock generator falls back to a plain string for types it does not
know, so it would otherwise pre-fill a file field with "test". New
``upload_variable_names`` and ``without_upload_values`` strip those values;
``needs_upload_inputs`` is re-expressed on top of the first rather than
duplicating the type check.

The run id already reaches a client over SSE, which is enough to open the
run on the canvas while the page is up. It is not enough afterwards: SSE
frames do not survive a reload, and the persisted card's ``run_ids`` holds
BUILDER run ids -- uuid4s the engine mints, which resolve to nothing
outside it. So on reopening a session the card was the only record of the
result, and the canvas view was unreachable.
Put ``dify_run_id`` on TestResultCard, beside ``run_ids``, wired at all
nine construction sites across the Build, Edit and Fix flows. Now the
canvas is reachable from the durable conversation too, which is what makes
the card's ``output`` genuinely the client's choice to render or skip
rather than the only surviving copy.

Streaming the test run gives the user a live progress bar but no results:
NodeEvent carries node_id/title/status/error and nothing else, so a client
watching the stream learns which node is running, never what it produced.
The results already exist -- the run is a normal InvokeFrom.DEBUGGER draft
run, its node executions are in the database, and the editor's canvas
already knows how to render exactly that view. It was simply never told
which run to open.
So put the Dify run id where a client can reach it:
- NodeEvent gains run_id, filled from the streaming frame. Every non-ping
frame is stamped with workflow_run_id, so this arrives with the FIRST
node event -- while the run is still going, which is the point.
- The node SSE frame publishes it alongside the existing fields.
- mark_test_success / mark_test_error carry dify_run_id in both the Build
and Edit flows, so the terminal state names its run too.
This is what makes per-node results land on the graph, where a node's
inputs and outputs already have a home, instead of only as a JSON blob on
a conversation card.

Three minor whole-branch-review fixups:
- ResourceOption.readiness ("ready"/"missing_config") was computed but never
shown to the model: discover_resources's recommender prompt listed ids and
labels only, so it could recommend an unauthorized tool; _GAP_SYSTEM showed
readiness in the listing (assess_capability_gap) but never defined what
missing_config means. Both prompts now show readiness and state that
missing_config is installed-but-not-authorized, i.e. not usable -- pinned
with tests asserting the literal "missing_config" in the constructed
prompts.
- strings.py: dropped three orphaned catalogue entries ("Here's the initial
plan.", "Ask each time", "Prefer audited") -- the conflict-policy concept
they backed was removed end to end; nothing in the handlers emits them.
- core/workflow/generator/tool_catalogue.py: provider.need_credentials was
read OUTSIDE the per-provider try/except that already guards
get_tools()/tool parsing. This module is shared with the cmd+K /create and
/refine flows, so a provider whose property raised would break those too,
not just the Builder. Moved the read inside the try/except so a bad
provider is skipped like any other.

_terminal_output json.dumps'd a node's outputs with no length limit. Node
outputs are only truncated upstream at ~100,000 chars per string, so a
report-generating workflow -- the Builder's showcase case -- could push
hundreds of KB of JSON into a dify_builder_conversation_items row, the SSE
frame, and the localizer walk on every successful build.
Cap the rendered output at 2000 chars with a visible truncation marker
before it reaches TestResultCard.

run_draft's streaming path introduced Run.status="running" (outcome
genuinely unknown -- the progress stream ended before the run did) as a
third status alongside "succeeded"/"failed", but neither
handle_test_and_repair (Build) nor handle_verify (Fix) knew about it: both
treated anything short of "succeeded" as a failure, so a truncated run got
labeled "Test run -- Failed" and, in Build, had a graph repair diagnosed
and staged against it while the run might still be executing.
Both handlers now branch on status=="running" before the failure path: a
neutral notice explains the outcome couldn't be determined, and the flow
returns to a re-runnable waiting state (build.execution / fix.await_testdata)
without ever calling diagnose or propose_repair.

Add assess_capability_gap: one plain sentence naming a plan step nothing
installed can perform, or "" when the plan is covered. Grounded only in
installed resources -- there is no marketplace lookup, so it names a missing
CAPABILITY, never a product to install. A missing_config tool (installed but
unauthorized, from the prior task's real readiness) doesn't count as
covering a step either, since the model is shown each option's readiness
alongside its label and kind.
Wired through the full agent seam: the DifyBuilderAgent protocol, the real
LlmBuilderAgent (delegates to build.assess_capability_gap), and the
PlaceholderAgent test double (returns ""). handlers_build.py calls it
after discover_resources and, when non-empty, appends a NoticeItem beside
the existing empty-resources notice -- the two are independent and can
both fire.
Like its sibling cognition functions, it degrades to "" (never raises) on
no model, an LLM error, or an unparseable reply: a gap that can't be
assessed isn't a gap worth inventing. The sentence is LLM-generated prose
already in the user's language (json_language_instruction), not a
catalogue entry, so no static string was added.

A passing build test reported "All checks passed" and threw away the
run's actual node outputs. TestResultCard gains an `output: str` field
(pretty-printed JSON of the last node that produced anything, "" when
none); handle_test_and_repair's success card now populates it via a new
_terminal_output(per_node) helper.
_terminal_output is deliberately status-agnostic (no node.status filter):
per-node status spellings differ by source ("success" vs "succeeded"), and
a status filter that silently misses would defeat the point of the card.
FakeDifyPort (tests/unit_tests/core/dify_builder/fakes.py) gains a
settable run_outputs dict, seeded onto the success-path NodeOutput's
outputs, so tests can assert on what the card shows without hand-rolling
a Run.

handle_execution's run_test branch used to stop and ask a human for test
data any time none was prepared yet, even when every declared start
variable was something the agent could invent. Add
needs_upload_inputs(schema) -> bool (true only for a declared file /
file-list variable) and gate BUILD_AWAIT_TESTDATA on it: everything else
is now mocked inline via env.agent.generate_mock_inputs and the flow goes
straight to build.test_and_repair. A schema mixing text and file
variables still stops at the gate, since the file can't be invented.
Updates three full-build-flow tests whose generated graph has no file
start variable, so run_test now lands directly at build.review instead of
pausing at the testdata gate.

Code review finding: handle_review's re_fix branch and handle_reverted both
emitted PlanCard("Build plan", "v1") before falling through to
build.initial_plan's unconditional resource discovery, which falls through
again to confirm_resources -- which emits PlanCard("Build plan", "v1") a
SECOND time, now with resources bound. Before this task those two cards were
tagged v1 then v2, so they were visibly different plans; now both say v1,
so the loop-back shows the same plan card twice in one pass. Task 2 already
removed this exact duplicate from the straight-through path
(handle_goal_analysis); it should not survive on the loop-back and not on
the straight-through path.
Fix: handle_review's re_fix branch and handle_reverted still draft
fc.plan_items/fc.plan_version_tag (needed by discovery and the eventual
confirm_resources card) but no longer emit a PlanCard or claim cards=["plan"]
on their AssistantTurnItem (now cards=[], matching the existing
handlers_fix.py precedent for a turn with no card). There is now exactly ONE
plan card per pass, tagged v1, on every path: straight-through,
continue_adjusting, and retry_after_revert.
Updated the two direct-handler unit tests that asserted the now-removed
card, and extended test_review_continue_adjusting_then_reapprove_is_
idempotent (an end-to-end Runner-driven test) to assert re_fix adds zero new
plan cards and the subsequent confirm_resources adds exactly one, tagged v1.

Code review finding: handle_goal_analysis built its own ProgressReporter
(build-review-requirements/build-draft-plan) and finish()ed it, then
tail-called _discover_and_offer_resources, which built a SECOND reporter
under the SAME env.operation_id. ProgressReporter's revision counter starts
at 0 per instance, so the second reporter's activate/finish calls restarted
revision at 1 -- two progress events with revision 1 (and 2, and 3) under
one operation_id. contract.py's ProgressEventData docstring states revision
is monotonic within an operation_id; every other handler across the three
handler files uses exactly one reporter per step -- this was the sole
exception, on the most-travelled build path.
Fix: _discover_and_offer_resources now takes an optional `progress`
parameter. handle_goal_analysis passes its live (still-open) reporter
through instead of finishing it early; the helper adds the discovery steps
onto that SAME reporter via add_steps() and is the one that finish()es it.
handle_initial_plan (the continue_adjusting/retry_after_revert loop-back,
which has no reporter of its own -- a separate CAS commit/operation) still
gets progress=None and the helper builds a fresh one, unchanged.
Added test_submitting_requirements_progress_is_one_operation_with_monotonic_
revisions: drives the real Runner with submit_requirements, captures every
emitted ProgressEventData, and asserts a single operation_id with strictly
increasing, non-repeating revisions across all four progress steps.

Code review finding: the plan card's version_tag was renumbered v2 -> v1
in an earlier commit, but handle_resource_recommendation's own reply_text
still read "Plan v2 ready for approval." -- a card that says v1 next to
prose that says v2 is worse than leaving both at v2, since it's exactly
the user-visible inconsistency the renumber exists to eliminate.
Updated the reply_text to "Plan v1 ready for approval." and its matching
entry in the strings.py literal catalog, so test_catalog_covers_handler_
literals keeps passing for the right reason (a registered v1 string, not
a stale v2 one). Grepped the whole of core/dify_builder/ for any other
quoted v2/v2.1 string this renumber might have missed -- this was the
only one.

Code review finding: build.initial_plan was left in _WAITING with zero
_ACTIONS_FOR entries but a handler still gated on find_resources. Since a
waiting state settles the runner's advance loop (is_waiting(next_state) ->
settled), continue_adjusting from build.review landed a session there with
no button the FE could render and no action the handler would accept --
the loop-back could never advance.
Reclassify build.initial_plan as working (state.py _WORKING, not _WAITING):
it is now a genuine pass-through step, matching build.test_and_repair /
build.publish / build.governance_feedback. handle_initial_plan drops its
find_resources gate and runs resource discovery unconditionally on entry;
the runner drives it with the action already consumed and falls straight
through to build.resource_recommendation within the same advance() call.
Removed the now-stale BUILD_INITIAL_PLAN entry from service.py's
_BACKEND_ACTIONS_FOR (no action to gate on any more) and the compensating
exemption it required in test_every_backend_waiting_action_has_a_ui_path
(the invariant now holds with no special case).
Added a state-classification test (test_build_initial_plan_is_working_not_
waiting) and an end-to-end regression driving the Runner from build.review
through continue_adjusting with no find_resources action ever sent
(test_continue_adjusting_reaches_resources_without_find_resources_action),
which is the scenario this fix exists to unwedge. Fixed the two existing
idempotency flow tests that asserted the old (broken) two-step loop-back.

handle_capability_check now advances a session that already carries a goal
(fc.goal_text set at creation) on ANY turn, not only send_goal -- the
composer already carried the goal in, so requiring a further send_goal
click was a second decision-free gate. A goal-less (create-from-blank)
session still waits for send_goal to supply one; that action id stays in
_ACTIONS_FOR for exactly that case.

With build.initial_plan's plan card gone (previous commit), the plan card
emitted by handle_resource_recommendation on confirm_resources is now the
FIRST and only plan card a build shows -- so it becomes v1 instead of v2.
The build-complete plan card in handle_plan_approval follows suit,
v2.1 -> v1.1. A build no longer displays "the same plan twice under two
version numbers".

submit_requirements now tail-calls a shared _discover_and_offer_resources
helper straight into build.resource_recommendation, instead of stopping at
build.initial_plan to show a plan card the user must click through with no
real decision to make. The resource-discovery body (progress reporting,
discover_resources, ResourceSelectCard, empty-options notice, assistant
turn) is extracted verbatim into that helper so the straight-through path
and the continue_adjusting/retry_after_revert loop-back (which still
re-enters at build.initial_plan and still requires find_resources) share
one implementation instead of drifting apart.
build.initial_plan survives as the loop-back target but now offers no UI
action (_ACTIONS_FOR entry removed); its handler still accepts
find_resources at the backend for that loop-back.

conflict_policy field on the (unused) ResourcesPayload contract type.

The main merge added Azerbaijani (#42291) as a console locale. The naming
fallback keys its "New app" stem by console locale, so a new locale without a
stem silently falls back to English; the catalog-completeness test caught it on
rebase, which is what that test exists for.

discover_resources initialised its selection to the entire tenant inventory and
only replaced it when the model returned a non-empty pick, so three paths -- no
model, a model that picked nothing, a failed call -- recommended everything. On
a workspace with 57 resources that is not merely noisy: the client pre-checks
every recommendation and submits them all by default, and bind_resources then
appends all 57 labels to the last plan item, which is the text fed to the graph
generator.
Recommending nothing is the honest answer when there is no signal. The card is
still emitted so the confirm gate keeps its active interaction and a later pass
cannot inherit a stale one, and a notice says why rather than leaving a blank
card. The conflict-policy control no longer renders over an empty list.
The test that should have caught this used a one-resource catalog, where "all"
and "none" are indistinguishable; it now uses 57.

Spec N4 has the build-complete card headline read "<App name> is ready", with
the annotation 名字只在回复句里念一次；记录卡上不出现 -- said once, in that
sentence, and never repeated on the completion receipt. We said it nowhere: the
card was titled "Build plan" and the engine had no app name to say.
DifyBuilderContext now carries app_name, seeded at session creation through a
get_app_name_fn seam alongside the existing revision/authorize ones. Env.rename_app
returns the name the database actually took rather than None, so the refine
records what landed instead of what it proposed -- the service normalizes after
the engine hands off, and the two can differ.
The headline is interpolated, so it gets a strings.py template or it would
survive localization untranslated. That pattern matches almost anything ending
in "is ready", so it sits last and every more specific template gets first
refusal.
The receipt already omitted the name; there is now a test pinning that.

Two App Builder spec changes that share the Builder session contract.
Naming (spec N1-N3): an app created from the homepage prompt is no longer named
by the user. core/dify_builder/naming.py cuts the prompt's opening clause at
create time -- instant and infallible, since it runs inside POST /apps -- and
CreateAppPayload.name becomes optional alongside a new prompt field. The Builder
then refines that name once during goal analysis, where a model and the detected
reply language are already in hand, so the judgement calls that are
English-shaped in pure Python (dropping an imperative lead-in, spotting a
contentless prompt) work in any language. Plan approval freezes the name.
Card options: SessionView gains a Decision carrying the gate's choice as options
inside the card plus a fixed confirm/cancel pair, replacing a button row whose
shape changed at every state. Option ids are the old action ids untouched, so
resolve_action_kind and the per-state legality check are unchanged, and
SessionView.actions keeps being populated -- the deployed web client goes on
working until it reads decision instead.
The regenerated console OpenAPI doc also picks up ErrorCard.diagnostics, missed
when cc9ca8b1dd landed.

api pods lose their logs on restart, so a failed build's real cause
("Workflow generator: structural validation failed: ...") could only be read
from a pod log that may already be gone. Session 01a08fd0 hit exactly that.
Carry the generator's own diagnostics back with the result instead:
BuildNodesResult and ErrorCard gain a ``diagnostics`` list, and build_nodes
records one entry per failed generation attempt -- initial AND the corrective
retry, so an error that changes between attempts stays visible -- plus the
all-rejected and exception paths.
Each entry holds a server-side UTC ``at`` (so the surviving pod-log window can
be searched around it), ``source``, ``attempt``, the generator's ``message``
(the same text the server logs), its ``codes``, and the full structured
``errors`` including ``node_id``. That is strictly more than the log line
carries: for an UNRESOLVED_REFERENCE the export now names the offending node.
The list rides in the ErrorCard's item payload, which is what the streamed
conversation item -- and therefore the exported debug log -- preserves. It is
not rendered in the UI. Retries that eventually succeed keep their breadcrumbs.
Deliberately not mirroring the "structural validation failed" prefix: build.py
cannot tell structural failures from the rest without duplicating the
generator's code taxonomy, which would go stale.

When build-generate-graph failed at plan-approval, the error card always
showed one hardcoded generic message regardless of the actual cause
(UNRESOLVED_REFERENCE, non-object JSON, credit_balance_exhausted, ...).
Root cause: build_nodes() returned only list[MutationIntent]; on failure it
returned [], so the reason was logged internally but never reached the
handler, which had nothing to show but a fallback string.
Thread the reason out: build_nodes now returns BuildNodesResult{intents,
error}. _generation_error_text() extracts the best reason (top-level error
-> joined errors[].detail/message/code -> generic fallback), and every
failure path populates .error (generator error, all-intents-rejected, and
the except path via str(exc) so provider errors surface verbatim).
handle_plan_approval builds the ErrorCard body from build_result.error when
present, keeping the generic sentence only as a genuine fallback.

A verify/affected-path run that fails because the workflow references a model
that isn't configured/available (ModelNotExistError, "Model X does not exist",
provider/credentials errors) was routed into the config-repair path -> diagnose
+ propose_repair kept proposing graph mutations (if-else / check nodes) that
can't fix a missing model, thrashing across rounds.
Add model_config_error_text() (classifier parallel to is_input_failure; pairs an
existence/credential signal with a model/provider/credential token so unrelated
"<node> does not exist" faults aren't swallowed). In both build and edit failure
branches, when it matches, surface a clear "model not configured" diagnosis with
NO staged repair and route to the await-repair gate: the user configures the
model (global update_model) or changes it, then re-runs. Catalog the two new
user-facing strings so the reply-language layer localizes them.

Build wrote the Builder's session/cognition model (e.g. deepseek) into every
generated node's model block, ignoring the model the user picked at resource
confirmation (e.g. gpt). _ground always used the generation model, and the
selected model resource only reached the plan as label text (bind_resources) —
so a workflow got a model with no runtime credentials -> ModelNotExistError ->
instant test failure.
Thread the selected resource_ids from resource_selection through
agent.build_nodes into build.build_nodes, resolve the selected MODEL resource
(id is `{provider}/{name}`) via _selected_workflow_model, and ground node model
blocks to it — falling back to the session/generator model when the user
selected no model. The generator still runs on the session model (cognition);
only the built workflow's runtime model follows the user's choice.

Follow-up to the reply-language feature. The update_model action commits its
"Model changed to <name>" notice directly via compare_and_advance, bypassing
Runner._commit and thus the Env.localize_items hook, so that one notice stayed
English. Localize it in the service (when the session has a detected
reply_language) with a "Model changed to {name}" catalog template that
translates the frame and re-inserts the model name verbatim.

Follow-up to the reply-language feature. `_model_or_none` was private to
LlmBuilderAgent, so the advance-task wiring reached it via a fragile
`getattr(agent, "_model_or_none", lambda: None)`. Make it part of the
DifyBuilderAgent protocol (typed `object | None` to keep the pure port free of
any model-runtime import) and implement it on every conforming agent
(LlmBuilderAgent renames the private method public; PlaceholderAgent and the
test doubles return None). The Localizer wiring now uses `agent.model_or_none`
directly. Also drops the useless-return ruff nit in the wiring test.

Final-review fix wave for the "reply in the user's input language" feature:
- serde.py: context_from_dict omitted reply_language from the explicit field
allowlist, so it round-tripped to "" on every read despite context_to_dict
(asdict) serializing it -- the localization feature silently no-op'd after
the first persisted write. Added it to the constructor call; TDD'd with a
failing-then-passing round-trip test in test_serde.py.
- localize.py: Localizer._cache was per-instance, but a fresh Localizer is
built per advance-task invocation, so the static string catalog was
re-translated every turn instead of once per language. Moved the cache to a
module-level _TRANSLATION_CACHE dict (safe to share: keys are
tenant/session-independent catalog-string+language pairs); added an autouse
fixture in test_localize.py to clear it between tests for isolation.
- localize.py: detect_language and _fill_cache called self._model_provider()
outside their try/except, violating the Env callback contract that these
must never raise. Moved both calls inside their try/except so a raising
provider degrades to the existing safe fallback instead of propagating into
advance/_commit.
- strings.py: documented that Template.translate_fields is advisory only --
the Localizer re-inserts all captured groups verbatim and does not consult
it. No behavior change.
uv run --project api pytest tests/unit_tests/core/dify_builder tests/unit_tests/services/dify_builder -q
-> 722 passed.
