Dedupe and Merge

Paste this into an assistant that can read the web, such as Claude, ChatGPT or Cursor. It reads the specification and the current LangGraph documentation, then writes two files: the graph, and a note on what did not survive the translation. Read the note first. What a runtime cannot express is the part worth arguing about, and this process is a draft to argue with.

Convert the business process below into a runnable LangGraph graph:
one Python file with a TypedDict state, a StateGraph, nodes, edges,
conditional edges and a checkpointer.

The document is a reference process written to the Agent Processes
specification. Read the specification before you start, because it defines
terms that look ordinary and are not:

  https://agentcatalog.com/spec/agent-processes

Sections 6 (the phase graph), 6.5.1 (exception edges), 6.7.1 (deviations),
7 (automation) and 8 (handoffs) are the ones this conversion turns on.

Then read the current documentation for the primitives you will need, rather
than relying on what you remember of the API:

  https://docs.langchain.com/oss/python/langgraph/interrupts
    interrupt() and Command(resume=), which is how a gate stops a run
  https://reference.langchain.com/python/langgraph/graph/state/StateGraph
    StateGraph, add_edge, add_conditional_edges, defer

WHAT THE DOCUMENT ASKS FOR

These hold wherever the process lands, and they matter more than style.

1. Each phase under `phases:` becomes one step, and keeps its name.

2. `after:` gives the edges. `after: a + b` is a join and waits for BOTH.
   Reading it as "either" is the defect the specification calls out by name.

3. Every handoff carries a key in square brackets. Each key becomes one field
   on the run's state, named exactly as the key with hyphens turned into
   underscores, and the sentence beside it becomes that field's comment. The key
   is the stable name; the sentence is prose that may be rewritten.

4. A phase MUST NOT begin before its inbound handoff exists. Where that is
   checkable, check it in the step rather than assuming it.

5. `automation: never` is a gate a person signs. The run stops there and does
   not continue until a person's decision comes back. Do not turn one into a
   notification, a log line, or an automatic transition, whatever the queue
   looks like.

6. Each line under `deviations:` is a backward or sideways edge, returning to
   the phase named on the right. The key in brackets names it, and that name
   belongs in the code.

7. A phase whose `after:` reads like "X or Y, whichever could not finish" is an
   exception edge: it is entered when those phases FAIL, not when they succeed.
   Do not wire it as an ordinary successor.

8. Anything in angle brackets is a blank the adopting organization fills in.
   Leave each one as a named constant at the top of the file with a TODO. Do not
   invent a value, a threshold or a date.

9. Record the document's `from:` line at the top of the file, so it says which
   reference process and which version it was generated from.

10. Run-scoped lines under `run-scoped:` are work that runs alongside the whole
    process rather than at one point in it, and a run may not close while one is
    unfinished. Say in the code what you did about them, including if the answer
    is that the runtime has nowhere to put them.

HOW THAT LOOKS IN LANGGRAPH

11. A phase is a node added with `add_node`, under the phase's own name.

12. The state is a TypedDict. Each handoff key is one field on it.

13. A join is the trap. `add_edge(["a", "b"], "c")` looks right and releases
    once: when a backward edge re-enters ONE arm, the joined node never runs
    again, and the run ends early reporting success rather than raising. Mark the
    joined node `defer=True` and re-check inside it that both inbound handoffs
    exist.

14. A gate is `interrupt()` inside the node, resumed with `Command(resume=...)`.
    The platform lets anything at all call resume, so require the resumed value to
    name a person and a date and refuse anything else. Say in the fidelity note
    that this proves only that whoever resumed typed a name, because
    `Command(resume=True)` from a scheduled job is indistinguishable from a person
    signing.

15. A deviation is `add_conditional_edges` with a routing function named after
    the key in brackets.

16. Pass a durable checkpointer rather than taking the in-memory default. The
    gates wait days, and the default loses every paused run on restart.

17. Leave every phase body unimplemented, raising until somebody registers an
    implementation. The automation level is a blank, so writing a body would
    answer on the adopter's behalf whether an agent may do that work.

Produce a second file alongside it, `FIDELITY.md`, and treat it as the more
important of the two. The code is for whoever builds this. The fidelity note
is for whoever has to decide whether this platform suits the process at all,
and that is usually a different person who will never read the code.

It has three parts.

**What came across.** Briefly: how many phases became steps, how many handoff
keys became state fields, which gates stop the run, which deviations became
edges. Counts and names, not reassurance.

**What did not, and what was done instead.** One entry per gap. For each one,
say what the document requires, what the platform can actually express, what
you did in its place, and what breaks if somebody later removes your
workaround. This last part matters most: a workaround nobody understands is a
workaround somebody deletes.

**What a person still has to decide.** The blanks are not a translation
failure, they are the point of a reference process, so list what has to be
filled in before this could run against anything real, and say which of those
choices the platform constrains.

Write it in plain English for somebody who has not read the specification, and
do not soften it. A translation of a reference process is a draft to argue
with, not a build artifact, and the honest account of what was lost is the most
useful thing you will produce.

Here is the process document.

             of any new set until that run closes
goal: every set of records that names one real thing ends as one
      record, with nothing either record held lost, and every merge
      reversible for <how long>
phases:
  take-in-set     - system: the records proposed as one thing, what

handoffs:
  take-in-set -> read-rule [duplicate-set]: the records proposed as one
    thing, and what proposed them
  read-rule -> pull-records [match-rule]: the rule, the fields it
    matched on, and the strength it matched at
  pull-records -> score-match [record-contents]: every field on each
    record, with what is attached to each one
  score-match -> route-unsure [match-score]: the score, the model
    version, and the inputs it was computed from
  route-unsure -> confirm-one [records-for-review]: the two records
    side by side, the score, and the fields the rule matched on
  confirm-one -> choose-survivor [merge-confirmation]: a person's
    answer, with their name and the date, and which record they called
    the real one
  choose-survivor -> settle-fields [surviving-id]: the surviving id,
    and the reason it was chosen over the other
  settle-fields -> keep-loser [settled-fields]: the winning value for
    every field, each one naming the record it came from
  keep-loser -> move-related [kept-losing-values]: the losing values as
    stored, so the merge can be reversed from them
  move-related -> check-consent [repointed-records]: everything now
    pointing at the survivor, and anything that could not be repointed
  check-consent -> tell-owners [consent-position]: the consent position
    carried onto the survivor, channel by channel, and what it took
    away
  tell-owners -> merge [owners-told]: both owners told, with the date
    they were told
  merge -> check-merge [merge-result]: the merge as written, the
    surviving id, and the closed record pointing at it
  check-merge -> report-merge [merge-check]: the before and after
    counts, and anything that does not reconcile
  check-merge -> undo-merge [what-is-missing]: what the check found
    missing, so the reversal knows what it is putting back
  report-merge -> record-learnings [merge-report]: the merges of the
    period, by rule, with the ones a person overturned
deviations:
  confirm-one -> record-learnings [not-one-thing]: the person says the
    two records are two real things, so nothing is merged and the
    survivor, the fields, the moves and the report are all passed over,
    with both records marked as compared
  check-consent -> settle-fields [consent-records-disagree]: the two
    consent records disagree, so the fields are settled again with the
    stricter position carried
  tell-owners -> confirm-one [owner-objects]: an owner objects after
    being told, so the merge holds and the confirmation is taken again
    with what the owner knows written down
  check-merge -> move-related [something-did-not-move]: something is
    still pointing at the closed record, so the move runs again rather
    than the closed record being reopened
  check-merge -> undo-merge [merge-lost-a-value]: the merge lost a
    value, so the reversal runs from what keep-loser stored
bindings:
  roster:  <who holds each role - agents claiming the abstract agents
           above, and named people for the record owners and whoever
           clears the review queue>
  systems: the CRM (write), the activity history (write),
           the marketing database (write), the consent record (write),
           the file store (write), <your data warehouse> (read)
  data:    the matching model at a version, <your survivor rule>,
           <your field precedence>, the uniqueness key from <your
           record definition>
policy:
  a merge under <threshold> is confirmed by a person, and confirming is
    never delegated to an agent
  no value is dropped: what does not survive is stored against the
    surviving record with the record it came from
  the stricter consent position wins every merge, on every channel
  a merge is reversible for <how long>, and the reversal is available
    to the person who confirmed it
  a record inside an open merge is not offered to a second merge
  both record owners are told before the merge, not after
measures:
  cycle time: <target> from the set arriving to the merge, and
              <target> for the review queue
  accuracy: <target> share of confirmed merges never reversed
  volume: <sets per period>, split by the rule that proposed them
  quality gate: no merge without a stored losing value set and a named
                confirmer for anything under <threshold>
```

Paste this into an assistant that can read the web, such as Claude, ChatGPT or Cursor. It reads the specification and the current Agent Framework documentation, then writes two files: the workflow, and a note on what did not survive the translation. Read the note first. What a runtime cannot express is the part worth arguing about, and this process is a draft to argue with.

Convert the business process below into a runnable Microsoft Agent Framework workflow:
one Python file with Executor classes, a WorkflowBuilder, typed edges,
request_info gates and durable checkpoint storage.

The document is a reference process written to the Agent Processes
specification. Read the specification before you start, because it defines
terms that look ordinary and are not:

  https://agentcatalog.com/spec/agent-processes

Sections 6 (the phase graph), 6.5.1 (exception edges), 6.7.1 (deviations),
7 (automation) and 8 (handoffs) are the ones this conversion turns on.

Then read the current documentation for the primitives you will need, rather
than relying on what you remember of the API:

  https://learn.microsoft.com/en-us/agent-framework/workflows/human-in-the-loop
    ctx.request_info, @response_handler, and answering a parked run later
  https://learn.microsoft.com/en-us/agent-framework/workflows/checkpoints
    what a checkpoint holds, and allowed_checkpoint_types
  https://learn.microsoft.com/en-us/agent-framework/concepts/workflows/edges
    add_edge with condition, add_fan_in_edges, add_switch_case_edge_group
  https://learn.microsoft.com/en-us/agent-framework/concepts/workflows/state
    ctx.set_state and ctx.get_state as they actually are today

WHAT THE DOCUMENT ASKS FOR

These hold wherever the process lands, and they matter more than style.

1. Each phase under `phases:` becomes one step, and keeps its name.

2. `after:` gives the edges. `after: a + b` is a join and waits for BOTH.
   Reading it as "either" is the defect the specification calls out by name.

3. Every handoff carries a key in square brackets. Each key becomes one field
   on the run's state, named exactly as the key with hyphens turned into
   underscores, and the sentence beside it becomes that field's comment. The key
   is the stable name; the sentence is prose that may be rewritten.

4. A phase MUST NOT begin before its inbound handoff exists. Where that is
   checkable, check it in the step rather than assuming it.

5. `automation: never` is a gate a person signs. The run stops there and does
   not continue until a person's decision comes back. Do not turn one into a
   notification, a log line, or an automatic transition, whatever the queue
   looks like.

6. Each line under `deviations:` is a backward or sideways edge, returning to
   the phase named on the right. The key in brackets names it, and that name
   belongs in the code.

7. A phase whose `after:` reads like "X or Y, whichever could not finish" is an

   Do not wire it as an ordinary successor.

8. Anything in angle brackets is a blank the adopting organization fills in.
   Leave each one as a named constant at the top of the file with a TODO. Do not
   invent a value, a threshold or a date.

9. Record the document's `from:` line at the top of the file, so it says which
   reference process and which version it was generated from.

10. Run-scoped lines under `run-scoped:` are work that runs alongside the whole
    process rather than at one point in it, and a run may not close while one is
    unfinished. Say in the code what you did about them, including if the answer
    is that the runtime has nowhere to put them.

HOW THAT LOOKS IN MICROSOFT AGENT FRAMEWORK

11. Write for Python, and read those pages before writing a line. This API has
    moved: `set_shared_state`, `RequestInfoExecutor`, `RequestInfoMessage` and
    `send_responses_streaming` are all in the training data and none of them exist
    any more. The .NET workflow API differs in kind rather than in spelling, so a
    file written for one does not port by renaming.

12. A phase is a class deriving from `Executor` whose `super().__init__(id=...)`
    takes the phase name verbatim. The id is not cosmetic: a checkpoint stores a
    signature over the topology and the executor ids, so an id built from a run, a
    timestamp or a counter cannot be resumed into.

13. Give each phase a `@handler` method and move work on with
    `await ctx.send_message(...)`. A handler that returns without sending is a dead
    end: the branch stops, the run converges, and it reports success. So a phase
    you are deliberately leaving unimplemented must still send a placeholder
    onward. Do not stub with `raise NotImplementedError`, which fails the run
    instead of leaving it runnable.

14. `after: a` is `builder.add_edge(a, b)`. `after: a + b` is
    `builder.add_fan_in_edges([a, b], target)`, and the target's handler must be
    annotated `list[T]`, because a fan-in delivers one aggregated list rather than
    the separate messages. A handler typed for the single value is dropped as a
    mismatch with nothing raised.

15. The join is the trap here, and it is the opposite of LangGraph's. The
    barrier re-arms: it clears its buffer when it fires and then demands a fresh
    message from every source. So a deviation that re-enters ONE arm parks the
    run forever waiting for an arm that will not run again, and the workflow ends
    IDLE reporting success. Wherever a deviation re-enters one arm of a join,
    replace the barrier with an ordinary edge from each arm into a small executor
    that records each arrival with `ctx.set_state` and only forwards when every
    expected key is present, and say in a comment that putting `add_fan_in_edges`
    back reintroduces the stall.

16. A phase that is both a join target and a deviation target needs two
    handlers, one annotated `list[T]` for the barrier and one annotated `T` for the
    backward message. Write only the list handler and every backward edge into it
    is discarded as a type mismatch, silently.

17. `automation: never` is `await ctx.request_info(request_data=...,
    response_type=...)` inside the phase, answered by a `@response_handler` on the
    same executor whose annotations match those exact types. The run parks at
    `IDLE_WITH_PENDING_REQUESTS` and the host answers with
    `workflow.run(stream=True, responses={request_id: value})`. If no handler
    matches the pair, the framework logs a warning and parks anyway, so the gate
    reads as working right up until somebody asks why the approval did not take.

18. A gate is only a gate if the wait survives a restart, so pass
    `checkpoint_storage=FileCheckpointStorage(...)` to the builder. Checkpointing
    is off by default and `InMemoryCheckpointStorage` reads as configured while
    persisting nothing. Register every handoff payload type in
    `allowed_checkpoint_types`, or the first restore raises. Anything an executor
    keeps as an instance attribute is absent after a restore unless you export it
    from `on_checkpoint_save` and read it back in `on_checkpoint_restore`, and it
    comes back empty rather than missing.

19. Each line under `deviations:` is `builder.add_edge(source, earlier,
    condition=fn)` with `fn` named after the key. Cycles are legal and unchecked,
    but raise `max_iterations` well above its default of 100, because several live
    cycles will exhaust a budget sized for a straight line and fail with a message
    about convergence that reads like a broken graph. Keep the ordinary forward
    edge unconditional and add each deviation beside it: a condition that returns
    false is dropped with no event, so a forward path expressed as a condition
    dies silently on every normal run, which is most of them.

20. Handoff values go in `ctx.set_state(key, value)` and come back from
    `ctx.get_state(key)`, untyped and unchecked. A write is visible to its writer
    at once and to everyone else only in the next superstep, and two writers of one
    key in a superstep keep the last write. Never read a key in the same superstep
    another phase wrote it.

21. There are no timers, no deadlines and no scheduled wakes. Nothing in
    `run-scoped:` becomes an executor and `by:` has no expression at all, so write
    them as comments naming where they start and stop, and say plainly in the
    fidelity note that a run can close over an unfinished run-scoped line. Do not
    fake a deadline with a sleep inside a handler, which blocks the whole superstep
    barrier, and never let an expiring wait release a gate.

Produce a second file alongside it, `FIDELITY.md`, and treat it as the more
important of the two. The code is for whoever builds this. The fidelity note
is for whoever has to decide whether this platform suits the process at all,
and that is usually a different person who will never read the code.

It has three parts.

**What came across.** Briefly: how many phases became steps, how many handoff
keys became state fields, which gates stop the run, which deviations became
edges. Counts and names, not reassurance.

**What did not, and what was done instead.** One entry per gap. For each one,
say what the document requires, what the platform can actually express, what
you did in its place, and what breaks if somebody later removes your
workaround. This last part matters most: a workaround nobody understands is a
workaround somebody deletes.

**What a person still has to decide.** The blanks are not a translation
failure, they are the point of a reference process, so list what has to be
filled in before this could run against anything real, and say which of those
choices the platform constrains.

Write it in plain English for somebody who has not read the specification, and
do not soften it. A translation of a reference process is a draft to argue
with, not a build artifact, and the honest account of what was lost is the most
useful thing you will produce.

Here is the process document.

             of any new set until that run closes
goal: every set of records that names one real thing ends as one

  check-consent   - runs assessment: the two consent records compared,
                    with the stricter position carried onto the

                    by: <hours>               automation: <level>
  merge           - system: the merge is written, and the losing
                    record closes as merged with a pointer to the

                from: route-unsure   until: run close
handoffs:
  take-in-set -> read-rule [duplicate-set]: the records proposed as one
    thing, and what proposed them
  read-rule -> pull-records [match-rule]: the rule, the fields it
    matched on, and the strength it matched at
  pull-records -> score-match [record-contents]: every field on each
    record, with what is attached to each one
  score-match -> route-unsure [match-score]: the score, the model
    version, and the inputs it was computed from
  route-unsure -> confirm-one [records-for-review]: the two records
    side by side, the score, and the fields the rule matched on
  confirm-one -> choose-survivor [merge-confirmation]: a person's
    answer, with their name and the date, and which record they called
    the real one
  choose-survivor -> settle-fields [surviving-id]: the surviving id,
    and the reason it was chosen over the other
  settle-fields -> keep-loser [settled-fields]: the winning value for
    every field, each one naming the record it came from
  keep-loser -> move-related [kept-losing-values]: the losing values as
    stored, so the merge can be reversed from them
  move-related -> check-consent [repointed-records]: everything now
    pointing at the survivor, and anything that could not be repointed
  check-consent -> tell-owners [consent-position]: the consent position
    carried onto the survivor, channel by channel, and what it took
    away
  tell-owners -> merge [owners-told]: both owners told, with the date
    they were told
  merge -> check-merge [merge-result]: the merge as written, the
    surviving id, and the closed record pointing at it
  check-merge -> report-merge [merge-check]: the before and after
    counts, and anything that does not reconcile
  check-merge -> undo-merge [what-is-missing]: what the check found
    missing, so the reversal knows what it is putting back
  report-merge -> record-learnings [merge-report]: the merges of the
    period, by rule, with the ones a person overturned
deviations:
  confirm-one -> record-learnings [not-one-thing]: the person says the
    two records are two real things, so nothing is merged and the
    survivor, the fields, the moves and the report are all passed over,
    with both records marked as compared
  check-consent -> settle-fields [consent-records-disagree]: the two
    consent records disagree, so the fields are settled again with the
    stricter position carried
  tell-owners -> confirm-one [owner-objects]: an owner objects after
    being told, so the merge holds and the confirmation is taken again
    with what the owner knows written down
  check-merge -> move-related [something-did-not-move]: something is
    still pointing at the closed record, so the move runs again rather
    than the closed record being reopened
  check-merge -> undo-merge [merge-lost-a-value]: the merge lost a
    value, so the reversal runs from what keep-loser stored
bindings:
  roster:  <who holds each role - agents claiming the abstract agents
           above, and named people for the record owners and whoever
           clears the review queue>
  systems: the CRM (write), the activity history (write),
           the marketing database (write), the consent record (write),
           the file store (write), <your data warehouse> (read)
  data:    the matching model at a version, <your survivor rule>,
           <your field precedence>, the uniqueness key from <your
           record definition>
policy:
  a merge under <threshold> is confirmed by a person, and confirming is
    never delegated to an agent
  no value is dropped: what does not survive is stored against the
    surviving record with the record it came from
  the stricter consent position wins every merge, on every channel
  a merge is reversible for <how long>, and the reversal is available
    to the person who confirmed it
  a record inside an open merge is not offered to a second merge
  both record owners are told before the merge, not after
measures:
  cycle time: <target> from the set arriving to the merge, and
              <target> for the review queue
  accuracy: <target> share of confirmed merges never reversed
  volume: <sets per period>, split by the rule that proposed them
  quality gate: no merge without a stored losing value set and a named
                confirmer for anything under <threshold>
```

Paste this into an assistant that can read the web, such as Claude, ChatGPT or Cursor. It reads the specification and the current CrewAI documentation, then writes two files: the flow, and a note on what did not survive the translation. Read the note first. What a runtime cannot express is the part worth arguing about, and this process is a draft to argue with.

Convert the business process below into a runnable CrewAI Flow:
one Python file with a Pydantic state model, one Flow subclass, @start,
@listen, @router and a durable human feedback provider.

The document is a reference process written to the Agent Processes
specification. Read the specification before you start, because it defines
terms that look ordinary and are not:

  https://agentcatalog.com/spec/agent-processes

Sections 6 (the phase graph), 6.5.1 (exception edges), 6.7.1 (deviations),
7 (automation) and 8 (handoffs) are the ones this conversion turns on.

Then read the current documentation for the primitives you will need, rather
than relying on what you remember of the API:

  https://docs.crewai.com/en/concepts/flows
    Flow, @start, @listen, @router, and_, or_, state, kickoff, plot
  https://docs.crewai.com/en/learn/human-feedback-in-flows
    @human_feedback, the provider protocol, from_pending and resume
  https://docs.crewai.com/en/guides/flows/mastering-flow-state
    @persist and what persistence actually promises, which is less than it sounds

WHAT THE DOCUMENT ASKS FOR

These hold wherever the process lands, and they matter more than style.

1. Each phase under `phases:` becomes one step, and keeps its name.

2. `after:` gives the edges. `after: a + b` is a join and waits for BOTH.
   Reading it as "either" is the defect the specification calls out by name.

3. Every handoff carries a key in square brackets. Each key becomes one field
   on the run's state, named exactly as the key with hyphens turned into
   underscores, and the sentence beside it becomes that field's comment. The key
   is the stable name; the sentence is prose that may be rewritten.

4. A phase MUST NOT begin before its inbound handoff exists. Where that is
   checkable, check it in the step rather than assuming it.

5. `automation: never` is a gate a person signs. The run stops there and does
   not continue until a person's decision comes back. Do not turn one into a
   notification, a log line, or an automatic transition, whatever the queue
   looks like.

6. Each line under `deviations:` is a backward or sideways edge, returning to
   the phase named on the right. The key in brackets names it, and that name
   belongs in the code.

7. A phase whose `after:` reads like "X or Y, whichever could not finish" is an
   exception edge: it is entered when those phases FAIL, not when they succeed.
   Do not wire it as an ordinary successor.

8. Anything in angle brackets is a blank the adopting organization fills in.
   Leave each one as a named constant at the top of the file with a TODO. Do not
   invent a value, a threshold or a date.

9. Record the document's `from:` line at the top of the file, so it says which
   reference process and which version it was generated from.

10. Run-scoped lines under `run-scoped:` are work that runs alongside the whole
    process rather than at one point in it, and a run may not close while one is
    unfinished. Say in the code what you did about them, including if the answer
    is that the runtime has nowhere to put them.

HOW THAT LOOKS IN CREWAI FLOWS

11. Build a Flow, not a Crew. A Crew is a team of roles with no graph, no join,
    no persistence handle and no gate, and cannot express this document at all.
    Each phase is one method on a single `Flow` subclass, keeping its name with
    hyphens turned into underscores. A phase that genuinely needs role-based agents
    builds its own Crew inside its own method body, and the Flow stays the graph.

12. Declare the state as a Pydantic model bound as the type parameter,
    `class NegotiateTheAgreement(Flow[NegotiationState])`, and read and write
    `self.state.field`. Never use the untyped dict form: the handoff keys are this
    process's memory, and an untyped dict turns a misspelt key into a handoff that
    is silently absent. Keep the auto-injected `id` field, which is what every
    resume depends on.

13. `after: a` is `@listen(a)`. `after: a + b` is `@listen(and_(a, b))`. Never
    write `or_` where the document writes `+`.

14. Check every inbound handoff at the top of the method and raise if one is
    missing. `@listen` says when a method may run and says nothing about what is
    in hand when it does.

15. The join is the trap, and it is proven rather than theoretical. `and_()`
    empties its accumulator the moment it fires, so re-entering BOTH arms works
    forever, and re-entering ONE arm after it has fired leaves it holding a single
    trigger and waiting for the other for good. The cascade drains, CrewAI prints
    that the flow completed, and `kickoff()` returns normally. So for any joining
    phase that a deviation can send work back into, do not use `and_()` at all:
    make the join a `@router` that both arms trigger, which reads the state fields
    and emits its label only when every inbound handoff is present. A router is
    re-evaluated against durable state every time and is never suppressed by the
    once-fired set.

16. Do not write a phase as `@listen(or_(and_(a, b), "some_label"))`. There is
    one accumulator per listener, shared across every branch of its condition and
    wiped when any branch satisfies, so the label firing while the join is half
    full erases the arm that had already arrived.

17. `automation: never` is `@human_feedback(message=..., provider=...)` stacked
    under the method's `@listen`, with a provider whose `request_feedback` raises
    `HumanFeedbackPending`. The run then persists, returns that object from
    `kickoff()`, and a different process answers later with `from_pending(flow_id,
    persistence)` and `resume(text)`. Do not take the default `ConsoleProvider`,
    which calls `input()`: that gate exists only while somebody is watching a
    terminal, and a run started by a scheduler either hangs or takes an empty
    string.

18. Silence must not approve, and the platform's default is that it does. With
    `emit=[...]` set, an empty resume collapses to `default_outcome`, or to the
    first label when that is unset, with no model consulted and nobody named. Treat
    an empty or unrecognised answer as a refusal in your own router. And write the
    approver's name and the time onto the state yourself, because
    `HumanFeedbackResult` carries the text, the outcome and a timestamp but has no
    field for the person, which the specification requires.

19. Each line under `deviations:` is a `@router` named after the key, returning
    a label named after the same key, with the target subscribing as
    `@listen(or_(normal_trigger, "the_label"))`. Route rather than listen
    directly, because a router is re-evaluated on every cycle while a top-level
    `or_` listener is suppressed after it first fires.

20. An exception edge is a `try` and `except` around the failing phase's body,
    recording the failure on the state and emitting an exception label from a
    router. Wiring it as `@listen(or_(x, y))` fires when those phases SUCCEED, so
    the clearing phase would run on every healthy run.

21. An unimplemented phase is a method with the document's own sentence as its
    docstring and a bare `pass`, which is safe because listeners still fire on a
    `None` return. An unimplemented `@router` is not safe: returning `None` emits
    no label, every phase below it disappears from the run including the gates, and
    the flow reports success. A stub router must return a hard-coded label with a
    TODO beside it, or raise.

22. Turn persistence on with `@persist(SQLiteFlowPersistence(...))`, then treat
    every phase that performs a real act as something that will run twice.
    Persistence saves the state fields and nothing else, so a restart rehydrates
    the data and runs the graph again from `@start`: a flow that had already sent a
    written refusal sends a second one. Guard each acting phase with a state field
    it checks and sets.

23. There are no timers, no deadlines and no cadences, and `run-scoped:` has no
    counterpart at all. Put each `by:` value as a named constant, name the
    run-scoped lines in the module docstring as unimplemented obligations, and say
    in the fidelity note that no deadline in this document is enforced by anything.
    These absences produce no diagnostic whatsoever, which is exactly why they have
    to be written down.

Produce a second file alongside it, `FIDELITY.md`, and treat it as the more
important of the two. The code is for whoever builds this. The fidelity note
is for whoever has to decide whether this platform suits the process at all,
and that is usually a different person who will never read the code.

It has three parts.

**What came across.** Briefly: how many phases became steps, how many handoff
keys became state fields, which gates stop the run, which deviations became
edges. Counts and names, not reassurance.

**What did not, and what was done instead.** One entry per gap. For each one,
say what the document requires, what the platform can actually express, what
you did in its place, and what breaks if somebody later removes your
workaround. This last part matters most: a workaround nobody understands is a
workaround somebody deletes.

**What a person still has to decide.** The blanks are not a translation
failure, they are the point of a reference process, so list what has to be
filled in before this could run against anything real, and say which of those
choices the platform constrains.

Write it in plain English for somebody who has not read the specification, and
do not soften it. A translation of a reference process is a draft to argue
with, not a build artifact, and the honest account of what was lost is the most
useful thing you will produce.

Here is the process document.

handoffs:
  take-in-set -> read-rule [duplicate-set]: the records proposed as one
    thing, and what proposed them
  read-rule -> pull-records [match-rule]: the rule, the fields it
    matched on, and the strength it matched at
  pull-records -> score-match [record-contents]: every field on each
    record, with what is attached to each one
  score-match -> route-unsure [match-score]: the score, the model
    version, and the inputs it was computed from
  route-unsure -> confirm-one [records-for-review]: the two records
    side by side, the score, and the fields the rule matched on
  confirm-one -> choose-survivor [merge-confirmation]: a person's
    answer, with their name and the date, and which record they called
    the real one
  choose-survivor -> settle-fields [surviving-id]: the surviving id,
    and the reason it was chosen over the other
  settle-fields -> keep-loser [settled-fields]: the winning value for
    every field, each one naming the record it came from
  keep-loser -> move-related [kept-losing-values]: the losing values as
    stored, so the merge can be reversed from them
  move-related -> check-consent [repointed-records]: everything now
    pointing at the survivor, and anything that could not be repointed
  check-consent -> tell-owners [consent-position]: the consent position
    carried onto the survivor, channel by channel, and what it took
    away
  tell-owners -> merge [owners-told]: both owners told, with the date
    they were told
  merge -> check-merge [merge-result]: the merge as written, the
    surviving id, and the closed record pointing at it
  check-merge -> report-merge [merge-check]: the before and after
    counts, and anything that does not reconcile
  check-merge -> undo-merge [what-is-missing]: what the check found
    missing, so the reversal knows what it is putting back
  report-merge -> record-learnings [merge-report]: the merges of the
    period, by rule, with the ones a person overturned
deviations:
  confirm-one -> record-learnings [not-one-thing]: the person says the
    two records are two real things, so nothing is merged and the
    survivor, the fields, the moves and the report are all passed over,
    with both records marked as compared
  check-consent -> settle-fields [consent-records-disagree]: the two
    consent records disagree, so the fields are settled again with the
    stricter position carried
  tell-owners -> confirm-one [owner-objects]: an owner objects after
    being told, so the merge holds and the confirmation is taken again
    with what the owner knows written down
  check-merge -> move-related [something-did-not-move]: something is
    still pointing at the closed record, so the move runs again rather
    than the closed record being reopened
  check-merge -> undo-merge [merge-lost-a-value]: the merge lost a
    value, so the reversal runs from what keep-loser stored
bindings:
  roster:  <who holds each role - agents claiming the abstract agents
           above, and named people for the record owners and whoever

           the marketing database (write), the consent record (write),
           the file store (write), <your data warehouse> (read)
  data:    the matching model at a version, <your survivor rule>,
           <your field precedence>, the uniqueness key from <your
           record definition>
policy:
  a merge under <threshold> is confirmed by a person, and confirming is
    never delegated to an agent
  no value is dropped: what does not survive is stored against the
    surviving record with the record it came from
  the stricter consent position wins every merge, on every channel
  a merge is reversible for <how long>, and the reversal is available
    to the person who confirmed it
  a record inside an open merge is not offered to a second merge
  both record owners are told before the merge, not after
measures:
  cycle time: <target> from the set arriving to the merge, and
              <target> for the review queue
  accuracy: <target> share of confirmed merges never reversed
  volume: <sets per period>, split by the rule that proposed them
  quality gate: no merge without a stored losing value set and a named
                confirmer for anything under <threshold>
```

Paste this into an assistant that can read the web, such as Claude, ChatGPT or Cursor. It reads the specification and the current ADK documentation, then writes two files: the workflow, and a note on what did not survive the translation. Read the note first. What a runtime cannot express is the part worth arguing about, and this process is a draft to argue with.

Convert the business process below into a runnable Google ADK workflow:
one Python file with a Workflow, nodes, routed edges, a JoinNode,
RequestInput gates and a persisting session service.

The document is a reference process written to the Agent Processes
specification. Read the specification before you start, because it defines
terms that look ordinary and are not:

  https://agentcatalog.com/spec/agent-processes

Sections 6 (the phase graph), 6.5.1 (exception edges), 6.7.1 (deviations),
7 (automation) and 8 (handoffs) are the ones this conversion turns on.

Then read the current documentation for the primitives you will need, rather
than relying on what you remember of the API:

  https://adk.dev/graphs/routes/
    nodes, tuple chains, Event(route=), JoinNode, back-edges
  https://adk.dev/graphs/human-input/
    RequestInput and the rerun_on_resume handoff
  https://adk.dev/runtime/resume/
    ResumabilityConfig, resuming by invocation id, at-least-once tools
  https://adk.dev/graphs/data-handling/
    Event.output against state, and the selector syntax in instructions

WHAT THE DOCUMENT ASKS FOR

These hold wherever the process lands, and they matter more than style.

1. Each phase under `phases:` becomes one step, and keeps its name.

2. `after:` gives the edges. `after: a + b` is a join and waits for BOTH.
   Reading it as "either" is the defect the specification calls out by name.

3. Every handoff carries a key in square brackets. Each key becomes one field
   on the run's state, named exactly as the key with hyphens turned into
   underscores, and the sentence beside it becomes that field's comment. The key
   is the stable name; the sentence is prose that may be rewritten.

4. A phase MUST NOT begin before its inbound handoff exists. Where that is
   checkable, check it in the step rather than assuming it.

5. `automation: never` is a gate a person signs. The run stops there and does
   not continue until a person's decision comes back. Do not turn one into a
   notification, a log line, or an automatic transition, whatever the queue
   looks like.

6. Each line under `deviations:` is a backward or sideways edge, returning to
   the phase named on the right. The key in brackets names it, and that name
   belongs in the code.

7. A phase whose `after:` reads like "X or Y, whichever could not finish" is an
   exception edge: it is entered when those phases FAIL, not when they succeed.
   Do not wire it as an ordinary successor.

8. Anything in angle brackets is a blank the adopting organization fills in.
   Leave each one as a named constant at the top of the file with a TODO. Do not
   invent a value, a threshold or a date.

9. Record the document's `from:` line at the top of the file, so it says which
   reference process and which version it was generated from.

10. Run-scoped lines under `run-scoped:` are work that runs alongside the whole
    process rather than at one point in it, and a run may not close while one is
    unfinished. Say in the code what you did about them, including if the answer
    is that the runtime has nowhere to put them.

HOW THAT LOOKS IN GOOGLE ADK

11. Build a `Workflow` from `google.adk.workflow`, and pin `google-adk>=2.0` in
    a comment. Do not use `SequentialAgent`, `ParallelAgent` or `LoopAgent`: they
    are deprecated in favour of the graph, and they carry their own defects around
    state and control flow. The documentation moved to adk.dev, and anything you
    remember about nesting agents rather than drawing a graph is out of date.

12. Each phase is one node keeping its name. Take the node kind from how the
    phase resolves rather than from taste: a `human:` or `system:` phase is a plain
    Python function node, and a `runs` or `convenes` phase is an `Agent`.

13. `after:` gives the edges, written as tuple chains in `edges=[...]`, and the
    trigger is the `"START"` keyword. Take the order only from `after:` lines and
    never from the order the phases are listed in.

14. `after: a + b` is a `JoinNode`, and it must be guarded, because this is the
    worst trap of any runtime here. The join fires when every static predecessor is
    marked COMPLETED, nothing ever un-completes a node, and stored outputs are
    never cleared. So after a deviation re-runs one arm, the join fires the instant
    that arm finishes and hands the next phase LAST PASS'S value for every arm that
    did not re-run. It does not stall, it proceeds with stale data, and nothing
    logs. Stamp each arm's output with a pass counter or a content hash, and have
    the phase after the join compare the stamps and refuse to run when they
    disagree.

15. Each line under `deviations:` is a routed back-edge: a router after the
    phase on the left returning `Event(route=...)`, named after the key in
    brackets, with one arm going back to the phase on the right and one going
    forward. An unconditional cycle raises at construction, which is the one place
    this model checks your work. Nothing budgets a routed cycle, so add your own
    count and stop rather than looping forever.

16. Give every router an explicit `DEFAULT_ROUTE` arm, and route it to a phase
    that stops and asks a person. A route value matching no key writes a log
    warning, ends that branch, and lets the run finish reporting success with the
    rest of the process never having happened.

17. `automation: never` is a `RequestInput` node of its own, never an `Agent`
    asking a question. Decorate it `@node(rerun_on_resume=False)` and yield
    `RequestInput(message=..., payload=..., response_schema=...)`, so the run
    stops, persists, and delivers the person's answer to the node's successor as
    its typed input. A resumed workflow runs its tools at least once, so any
    irreversible act needs its own duplicate guard.

18. Make the gates durable or say plainly that they are not. Wrap the graph in
    `App(..., resumability_config=ResumabilityConfig(is_resumable=True))` and pass
    a persisting session service, never the in-memory one. Note in the file that
    the command line and the web UI cannot resume a run, so whoever releases these
    gates needs an operator surface that somebody has to write.

19. Every `Agent` in the graph gets `mode="single_turn"` and no `sub_agents`.
    A non-empty `sub_agents` list silently adds a transfer tool, and a model that
    uses it runs a different agent in this node's place while the graph's outgoing
    edge fires on schedule regardless: the topology is honoured perfectly and the
    work belongs to somebody else.

20. Model failure as a route, not as an exception. A node that raises does not
    propagate: the failure is caught, recorded, and shuts the workflow down without
    raising to the caller. So a phase that can fail catches its own failure and
    returns `Event(route="could-not-finish")`, and the exception phase hangs off
    that arm.

21. Keep every blank as a named module-level constant and never interpolate one
    into an `instruction=` string. Angle brackets and curly braces are ADK's own
    data selector syntax inside instructions, so a blank pasted verbatim stops
    being a blank and becomes a selector.

22. `by:` and `not-before:` have no expression, and `@node(timeout=)` is not
    one: it is an in-process wall clock that cancels the node and, because failures
    are swallowed, ends the run silently rather than recording a missed deadline.
    Nothing in `run-scoped:` has an expression either, and it must not be faked as
    an ordinary node, because a node has to be reached and has to finish before
    anything downstream starts, which is the opposite of what those lines mean.
    Leave both out of the graph and name them in the fidelity note.

Produce a second file alongside it, `FIDELITY.md`, and treat it as the more
important of the two. The code is for whoever builds this. The fidelity note
is for whoever has to decide whether this platform suits the process at all,
and that is usually a different person who will never read the code.

It has three parts.

**What came across.** Briefly: how many phases became steps, how many handoff
keys became state fields, which gates stop the run, which deviations became
edges. Counts and names, not reassurance.

**What did not, and what was done instead.** One entry per gap. For each one,
say what the document requires, what the platform can actually express, what
you did in its place, and what breaks if somebody later removes your
workaround. This last part matters most: a workaround nobody understands is a
workaround somebody deletes.

**What a person still has to decide.** The blanks are not a translation
failure, they are the point of a reference process, so list what has to be
filled in before this could run against anything real, and say which of those
choices the platform constrains.

Write it in plain English for somebody who has not read the specification, and
do not soften it. A translation of a reference process is a draft to argue
with, not a build artifact, and the honest account of what was lost is the most
useful thing you will produce.

Here is the process document.

handoffs:
  take-in-set -> read-rule [duplicate-set]: the records proposed as one
    thing, and what proposed them
  read-rule -> pull-records [match-rule]: the rule, the fields it
    matched on, and the strength it matched at
  pull-records -> score-match [record-contents]: every field on each
    record, with what is attached to each one
  score-match -> route-unsure [match-score]: the score, the model
    version, and the inputs it was computed from
  route-unsure -> confirm-one [records-for-review]: the two records
    side by side, the score, and the fields the rule matched on
  confirm-one -> choose-survivor [merge-confirmation]: a person's
    answer, with their name and the date, and which record they called
    the real one
  choose-survivor -> settle-fields [surviving-id]: the surviving id,
    and the reason it was chosen over the other
  settle-fields -> keep-loser [settled-fields]: the winning value for
    every field, each one naming the record it came from
  keep-loser -> move-related [kept-losing-values]: the losing values as
    stored, so the merge can be reversed from them
  move-related -> check-consent [repointed-records]: everything now
    pointing at the survivor, and anything that could not be repointed
  check-consent -> tell-owners [consent-position]: the consent position
    carried onto the survivor, channel by channel, and what it took
    away
  tell-owners -> merge [owners-told]: both owners told, with the date
    they were told
  merge -> check-merge [merge-result]: the merge as written, the
    surviving id, and the closed record pointing at it
  check-merge -> report-merge [merge-check]: the before and after
    counts, and anything that does not reconcile
  check-merge -> undo-merge [what-is-missing]: what the check found
    missing, so the reversal knows what it is putting back
  report-merge -> record-learnings [merge-report]: the merges of the
    period, by rule, with the ones a person overturned
deviations:
  confirm-one -> record-learnings [not-one-thing]: the person says the
    two records are two real things, so nothing is merged and the
    survivor, the fields, the moves and the report are all passed over,
    with both records marked as compared
  check-consent -> settle-fields [consent-records-disagree]: the two
    consent records disagree, so the fields are settled again with the
    stricter position carried
  tell-owners -> confirm-one [owner-objects]: an owner objects after
    being told, so the merge holds and the confirmation is taken again
    with what the owner knows written down
  check-merge -> move-related [something-did-not-move]: something is
    still pointing at the closed record, so the move runs again rather
    than the closed record being reopened
  check-merge -> undo-merge [merge-lost-a-value]: the merge lost a
    value, so the reversal runs from what keep-loser stored
bindings:
  roster:  <who holds each role - agents claiming the abstract agents
           above, and named people for the record owners and whoever
           clears the review queue>
  systems: the CRM (write), the activity history (write),
           the marketing database (write), the consent record (write),
           the file store (write), <your data warehouse> (read)
  data:    the matching model at a version, <your survivor rule>,
           <your field precedence>, the uniqueness key from <your
           record definition>
policy:
  a merge under <threshold> is confirmed by a person, and confirming is
    never delegated to an agent
  no value is dropped: what does not survive is stored against the
    surviving record with the record it came from
  the stricter consent position wins every merge, on every channel
  a merge is reversible for <how long>, and the reversal is available
    to the person who confirmed it
  a record inside an open merge is not offered to a second merge
  both record owners are told before the merge, not after
measures:
  cycle time: <target> from the set arriving to the merge, and
              <target> for the review queue
  accuracy: <target> share of confirmed merges never reversed
  volume: <sets per period>, split by the rule that proposed them
  quality gate: no merge without a stored losing value set and a named
                confirmer for anything under <threshold>
