feat(cases): add persistent workflows with same-task agent handoffs (#16959)

## Thinking Path

> - Paperclip manages AI agents and their work.
> - An agent workflow needs persistent facts and a safe way to transfer
work.
> - Creating a task for each phase splits the objective, discussion,
workspace, and review policy.
> - A case can retain the facts while one primary task moves between
agents.
> - Transfers must survive process failure and preserve private access,
budgets, and completion gates.
> - This pull request adds durable case handoffs, native case tools, and
read-only case pages.
> - Prompts describe the workflow. Existing task controls decide when
work can run and finish.

## Linked Issues or Issue Description

**Problem or motivation**

Prompt-driven agent teams need a persistent record that can move through
triage, implementation, verification, and correction. Ordinary
reassignment does not provide a durable instruction, safe release
barrier, or recoverable delivery receipt for an agent handing off its
own running task.

**Proposed solution**

Extend standalone cases with one primary task, a descriptive phase,
retained access sources, and a handoff ledger. Apply assignments after
source execution and workspace settlement. Deliver each transfer through
the existing durable wake queue. Provide `create_case`, `read_case`,
`update_case`, and `handoff_case` in the native runner. Creation
requires kickoff and explicit workflow text. An explicit handoff to
`done` closes the case when normal task completion is accepted.

**Alternatives considered**

Do not add a workflow engine, filesystem queue, configured state graph,
or one task per phase. The workflow document combines transition prose
with an optional Mermaid `stateDiagram-v2` map. The server does not
execute the diagram. The Pipelines experiment removed on master stays
removed.

**Roadmap alignment**

This extends Agent Reviews and Approvals, Enforced Outcomes, Bounded Run
Recovery, and Activity Log attribution. Existing approval, review,
budget, privacy, workspace, and responsible-user rules remain
authoritative.

Related work: [ordinary handoff wake
recovery](https://github.com/paperclipai/paperclip/pull/15019). This
feature adds a separate persisted case-handoff receipt and release
barrier.

## What Changed

- Add case routing fields, retained access sources, durable handoff
history, delivery leases, and replay-safe migrations.
- Keep the same primary task across agent phases. Preserve each
returning agent's own session and the task's workspace.
- Fence outgoing mutations, wait for provider and workspace release, and
recover delivery without duplicate task comments or runs. Recheck
current assignment permissions as the original caller before applying a
delayed transfer. Scope a run Stop to that run’s own handoff intents, so
repeated old Stop requests preserve newer work. Cancelling terminal
intent without a source run also requires fenced current task ownership,
including native retries and preparation with an old checkout. For Cloud
callers, revalidate current stack membership with an uncached Cloud RPC
and derive owner elevation from the current managed setting.
- Keep case reads, documents, assets, Audit, and live events inside
retained task/project permissions.
- Add native case creation/read/update/handoff tools. Store required
workflow text and initial documents on the first task. Page oversized
case facts and referenced document bodies through the dedicated tool
with bounded UTF-8 JSON, current routing versions, snapshot conflicts,
and current source authorization on every page.
- Add read-only case lists and detail pages, task-style list controls,
compact dotted field tables, linked handoff tasks, and case filters in
Audit.
- Add native/legacy integration tests, migration/restart tests, browser
coverage, and bounded live receipt fixtures. Extend the trusted sandbox
condition to cover the new subscription fixture profile.
- Hide obsolete paused-agent warnings on completed or cancelled task
threads.
- Synchronize the company-switch settings test with React effects after
a CI failure. Preserve its security assertions and production remount
behavior.

## Verification

The branch directly includes master `9ef434fe79`. The required `ci /
verify` and `ci / e2e` gates pass on head `765fccd67c`. [Current-head
CI](https://github.com/paperclipai/paperclip/actions/runs/39464348614)
passes typecheck, build, tests, and all eight browser shards. Security
checks pass. [Greptile gives this exact head
5/5](https://github.com/paperclipai/paperclip/pull/16959#issuecomment-6291156549),
with no unresolved review threads. The optional Paperclip Review check
remains queued because its assigned agent is paused. It is not a
required branch check. No check result was overridden.

Local workspace typecheck and build pass after the master merge, along
with database migration checks, token gates, map checks, Storybook
catalog checks, and the Copilot profile identity check. Standard builds
refresh Runner vendor output. Focused checks pass 2,008
API/paging/context tests and 7 strict case protocol tests. The final
commit changes one test fixture only; its ten tests, UI typecheck, and
token gates pass. No production source changed in that commit.

On current head `765fccd67c`, all **194 critical workflow tests**
executed and passed with no skipped tests in those files:

- 38 Stop/ownership tests, including board completion intent, native
retries, stale Stop, and preparation with an old checkout.
- 2 actual legacy process/HTTP handoff tests, including scratch failure,
a closed-stdio child that continues writing, and recovery through a
fresh worker after the process group stops.
- 5 migration tests, including SQL column metadata, preserved null
authority context, and all six prior-numbering receipts.
- 3 process-settlement and 5 scratch tests.
- 88 handoff-service, 18 heartbeat handoff, and 21 native case-tool
integration tests.
- 7 bounded case/document-read projection tests and 7 strict
protocol-contract tests.

The current CI checkout was `fed65d49`, merging `765fccd67c` into master
`9ef434fe79`. Its new document regressions reconstruct exact
Unicode/escaped bodies and revisions through real native authority and
authenticated HTTP with generic API tools disabled. They cover
case-owned, primary-task, and linked-task documents; routing on every
page; stale document snapshots; access loss and unlinking;
unrelated/foreign/private sources; system documents; and quarantined
content. Active-task document tools retain their existing behavior.
These are current-head test results from the first CI attempt; the
browser-only retry did not rerun these suites.

The full `64fdd3403f` CI failed one separate settings test: after a
company switch, it observed an unsettled API-key draft. The production
component and test were unchanged from prior green source. Production
switches remount both keyed settings layers; the test directly reused an
unkeyed view and used a timer tick instead of waiting for React effects.
The final commit replaces that fixture synchronization with React `act`.
The exact secret-clearing assertions and all timeouts remain unchanged.
The original assertion failure remains recorded; no unchanged retry was
used. The narrow unchanged baseline and fixed fixture each pass 10
tests.

The upstream result-paging merge preserves case capture namespaces and
current asset privacy. Its API integration suite executed 39 of 41 tests
successfully, with two skipped; the optional assigned-result PRP
integration test was skipped. Neither skipped suite is counted in the
194 critical tests or as live provider proof.

All 361 upstream migration entries and SQL bodies remain unchanged. Six
case migrations follow master as 0363–0368 with identical SQL hashes.
Official Drizzle generators produced the combined metadata and five
retained snapshots. Generation reports no schema changes, and the
snapshot drift test passes. The earlier `ce361ae5d0` CI passed on
attempt 1, including its then-current 179 critical tests. Fresh review
later identified unusable document references with generic API tools
disabled; the bounded document reads and ten additional authenticated
HTTP tests address that finding.

The full local `pnpm test:run` attempt was cancelled after this Mac
exhausted PostgreSQL semaphore capacity; it is **not** counted as a
pass. Later database attempts also stopped before assertions or skipped,
including one sandbox socket denial. Two original stale-Stop regressions
did reproduce the bug against the old source. A REST serialization
assertion passed after two preserved database-startup failures. No test
timeout was increased. All 194 assertions listed above executed and
passed in current-head CI. The complete 385-file, 3,963-test UI shard
also passed after the fixture repair.

A configured-provider receipt workflow passed 13 backend checks across
triage → implementation → verification → correction → done, using one
task and four work runs. The saved receipt is revision 2 with total 6
USD; case and task both closed. The original canonical attempt remains
failed because its browser assertion confused the terminal destination
with completed-task tooltips. The corrected full browser verifier passed
on the same retained database and original runs, with no additional
provider calls. The last clean-build browser readback is on
`6a86c54a53`; later changes affect recovery, authorization, bounded
reads, and settlement. Accounted work cost is a $1.010574 rate-card
estimate; provider billing and setup-probe usage are unavailable.

Copilot profile 49 passed the unchanged seven-fixture private protocol
pack (46/46 checks, no retries) and the product file-edit canary after
master's completion-replay change. All 60 bound implementation hashes
remain unchanged on the current source. Historical profile-47/48
identities and results remain intact. See the [profile-49 compatibility
record](https://github.com/paperclipai/paperclip/blob/codex/persistent-case-handoffs/doc/plans/2026-10-20-copilot-completion-recovery-compatibility-v49.json).
This is bounded compatibility evidence, not a fresh full matrix,
installed-package product test, or Daytona rollout.

Preserved CI failures and retries:

- On `20662930ac`, Slack managed setup failed a five-second success
assertion after reload. Its test/application path was unchanged from a
prior green head. One unchanged-source retry passed all 25 tests in that
shard; no source or timeout changed.
- On `9402b4f17a`, two CI workers received shutdown signals at 15:24:19
UTC. Neither log had an assertion failure before interruption. One
unchanged-source retry of each passed all Runner static checks and all
32 tests in browser shard 6; both aggregates passed. The next head,
`7b4374edaf`, passed all CI without retries.
- On `295f289b5a`, serialized shard 9 timed out during its first
device-login test, then the next test found an active login lease.
Direct login/test paths were unchanged from a prior green head. Cold
import plus a timed-out async body using the next test's mutable
actor/store is the supported fixture-race explanation; no request trace
proves that sequence. The original failure remains recorded. One
unchanged-source retry passed all 294 tests in 19 files, including all
41 device-login tests. No login source or timeout changed. The
subsequent `ce361ae5d0` CI passed without retries.
- On `64fdd3403f`, one company-switch settings assertion observed an
unsettled draft. The final test-only commit uses React `act` without
changing assertions, timeouts, or production code. On `765fccd67c`, all
ten settings tests and the complete 385-file, 3,963-test UI shard
passed.
- On `765fccd67c`, browser shard 3 completed the split-handoff
assertions, then cleanup received HTTP 500 from run cancellation after a
one-second PostgreSQL row-lock timeout. The extra chat run was reporting
completed work while teardown began. Cleanup stopped before restoring a
global experiment flag, causing a later assertion to fail. Relevant
production and test paths are unchanged from an earlier green commit.
Stop's lock order is consistent, and no nested self-lock was found; the
exact PostgreSQL blocker was not recorded. One unchanged-shard retry
passed. The original failure, trace, and downstream flag failure remain
recorded. No Stop implementation, cleanup assertion, or timeout changed.
The retry supports intermittent cleanup contention; it does not identify
the original blocking transaction.


## Risks

- Local process transfers require host-owned PID/group absence. Missing
or uncertain termination evidence keeps delivery pending, independently
of scratch setup.
- Handoff admission and task cancellation share execution ownership. New
regression tests cover temporary holds, late source writes, and
uncertain provider termination.
- Retained private sources use an intersection of existing permissions.
This intentionally fails closed when a source is missing or an existing
task cannot preserve that boundary.
- Migrations add tables and indexes. They preserve master history and
can replay over prior feature installs. Migration 0368 adds nullable
internal authorization provenance with no default or authority backfill.
Historical transfers still awaiting release without this context fail
closed; an operator must cancel them and request a new handoff.
- Delayed Cloud handoffs depend on the current Cloud membership RPC. An
unavailable, ambiguous, expired, or mismatched response holds the
handoff for retry; it does not reuse cached authority or grant access.
- Bounded reads reload and reauthorize the selected projection per page.
Underlying work grows with the data size and number of pages. Changed
data or routing requires restarting from offset zero without the old
snapshot.
- Phase names and workflow diagrams remain advisory. They do not satisfy
review or approval gates.
- This is a large, cross-cutting PR. The maintainer requested one PR for
the whole feature; the commits separate data, runtime, UI, and
qualification work.

## Model Used

OpenAI Codex, GPT-6 family, with tool use, code execution, and delegated
code review. The exact deployment model ID and context-window size were
not exposed in the session. Live fixture agents used the explicitly
configured provider model recorded in their test evidence.

 Paperclip uses PostgreSQL via [Drizzle ORM](https://orm.drizzle.team/). There are three ways to run the database, from simplest to most production-ready.
 
+### Persistent case handoffs
+
+Standalone `cases` add a nullable unique `work_issue_id`, a descriptive `phase`,
+and an integer `handoff_version`. Historical passive records have no primary task;
+native `create_case` requires kickoff plus explicit workflow text and creates its primary task atomically. This is
+separate from `pipeline_cases`.
+
+First-task `initialDocuments` use ordinary `documents`, `document_revisions`
+and `issue_documents` in the case kickoff transaction. No case document copies,
+pending seeds or new tables are introduced. Case read surfaces join accessible
+linked task documents; historical `case_documents` records remain unchanged.
+Required `workflow_document_text` uses the same tables, under ordinary task key
+`workflow`. It is committed before delivery and contributes to the idempotency
+fingerprint. Existing cases and tasks receive no inferred workflow or backfill.
+Authoring guidance recommends both a Mermaid `stateDiagram-v2` map and prose
+defining each transition. Neither representation is parsed into database states.
+
+`case_handoffs` retains the task/agent identities, principal-scoped idempotency
+key and request fingerprint, observed/applied bigint task status revisions,
+instructions/comment, source run, and stable wakeup receipt. Partial unique
+indexes permit only one pending handoff per task and case. The pending-attempt
+index and expiring lease support bounded delivery across controller restarts.
+The ledger states distinguish release waiting, assignment applied but admission
+pending, queue acceptance, and cancellation. Provider execution remains in the
+ordinary heartbeat tables.
+
+`actor_context` retains a versioned, server-derived authorization context for
+delayed assignment. It contains no credentials and is omitted from public
+handoff responses. Applying a delayed transfer rechecks the original caller's
+current assignment permissions. Historical pending transfers without this
+context fail closed; an operator can cancel them and request a new handoff.
+
+Terminal handoffs have `destination_kind = 'done'`, a null destination agent,
+and states `awaiting_completion` / `completed` with `completed_at`. They share
+pending task/case uniqueness with agent transfers but do not enter the delivery
+lease index or wake queue. Accepted ordinary task completion and terminal case
+closure commit together. No terminal intent is inferred from a case's status.
+
+`case_access_sources` stores retained logical issue/project identities without
+deletion cascades from those sources. A missing source denies access. The case
+is readable only when every source's existing permissions allow it; unlinking a
+task or changing presentation metadata cannot widen that set. The case handoff
+migration backfills historical project and linked-task sources conservatively
+and leaves all existing cases passive. Source identities are not grants.

 This project can run fully in local dev without setting up PostgreSQL manually.
 
+## Persistent case handoffs
+
+The Cases experiment supports prompt-driven agent workflows on one ordinary task.
+The application service owns transaction/idempotency and assignment policy;
+`case-handoff-delivery.ts` owns durable retry/lease and wake admission;
+`heartbeat/case-handoff-lifecycle.ts` owns execution release proof and stale-run
+mutation fencing. Keep network/process work outside the acceptance transaction.
+`heartbeat/process-settlement.ts` checks local process-tree absence independently
+of scratch-directory preparation. A local process handoff stays pending while
+the owned PID or process group is alive, or termination evidence is missing.
+HTTP adapters use their awaited nonprocess invocation contract instead of host
+PID probes. Stopping a run cancels its own intents; cancelling an unbound
+terminal intent additionally requires fenced, current task ownership.
+`case-context.ts` builds the bounded authorized case snapshot shared by native
+and legacy task preparation, including resumed sessions.
+
+Native case tools are `create_case`, `read_case`, `update_case`, and
+`handoff_case`. Native creation requires `kickoff` and delegates to the same
+principal-idempotent handoff service. Both `kickoff` and nonblank
+`workflow_document_text` are mandatory; missing either fails before any writes.
+The text is preserved in ordinary Markdown task document `workflow`, title
+`Workflow`, in the acceptance transaction. New-case handoff API requests require
+the same field. The workflow plus optional document seeds share a 200,000-character
+budget; `workflow` cannot appear in `initialDocuments`. Later phase handoffs omit
+the text; normal revision tools manage changes. Read `workflow` before routing:
+its reference is prioritized in case context, without injecting its full body.
+Recommend both a Mermaid `stateDiagram-v2` map and prose defining each transition's
+trigger, evidence, next agent, human wait/resume behavior and correction/escalation
+limits. State IDs match phase names and prose defines named edge outcomes.
+This guidance adds no server-enforced transition semantics. There is
+no passive creation branch or `createOnly` REST extension. Historical
+generic REST upsert semantics remain compatible. `initialDocuments` is valid only for
+new first-task kickoff; ordinary task documents and audit are committed before
+delivery. Case detail/context roll up authorized task document metadata through
+`case-task-documents.ts`; system keys and inaccessible task documents are
+excluded before the document limit. Standard task document tools handle new
+documents; historical case document REST/storage remains intact.
+`read_case` keeps small responses structured. Large responses return bounded
+`readPage.text` JSON chunks with case/task routing versions on every page. Use
+`section: "fields"` to retrieve the entire fields object, including large keys,
+strings, and arrays. Continue with the same `section` and `snapshot`, passing
+`offsetBytes: readPage.nextOffsetBytes` until it is null; concatenate the text
+before parsing JSON. A 409 means facts, accessible references, or routing changed:
+restart at offset zero without the old snapshot. Each page reauthorizes current case access through
+`GET /api/cases/:id?agentRead=true`; no generic API tool or asset grant is needed.
+`limitBytes` is 4–8192 UTF-8 bytes. Ordinary REST reads retain their existing full
+response, and ordinary `update_case` mutation receipts remain unchanged.
+Use `section: "document"` and `documentKey` for a historical case-owned body;
+add `documentIssueId` for a primary or currently linked task document. This
+selection retains the same bounded JSON paging and does not enable generic API
+tools. Each page checks current case access, task access, linkage, and document
+trust. System and quarantined documents are excluded. Document edits and routing
+changes invalidate the snapshot; restart from zero after a 409.
+Each page reloads case metadata and the complete selected body to check access
+and compute its snapshot. These limits bound the response, not total database
+work; the read cost grows with source size and the number of pages.
+
+Keep native schemas aligned with their services/routes. Transactional source
+run checks must precede case writes, so Stop or an accepted handoff cannot race
+an HTTP request into a late mutation. Generic API rollout settings do not remove
+these dedicated tools; case, mode and resource authorization still apply.
+Company deletion removes cases before task/agent dependencies. Individual agent
+purge preserves handoff attribution and returns `agent_case_history_retained`
+before destructive cleanup when history references that agent. Termination stays available.
+
+The native constructor preserves full case context for bootstrap and resume
+failure. Compatible continuations carry a versioned case projection tied to the
+actual prior native input and exact agent/task/session. Stable facts fingerprints
+include document revisions and accessible references, while phase/version and
+incoming instructions are refreshed separately. Do not use a prepared
+`contextSnapshot.paperclipCase` as proof that a compact provider turn received
+those facts. Legacy adapters continue to receive their bounded case snapshot.
+
+Start work through `handoff_case` or
+`POST /api/companies/:companyId/case-handoffs`. Subsequent calls use the same
+primary task and observed case/task revisions. GET the case's `/handoffs` for
+history; `/handoffs/:handoffId/retry` retries delivery without creating new work,
+and `/cancel` cancels pending delivery without reversing an applied assignment.
+Ordinary task completion leaves the case unchanged. For an existing primary
+task, `to: "done"` records a non-yielding terminal handoff; its `awaiting_completion`
+intent is settled atomically by the normal issue-service completion transaction.
+The case remains open during review or user waits. Stop/cancel/reassignment
+invalidate the intent. Keep terminal intents outside agent-transfer mutation
+fencing, outgoing yield detection and recipient dispatch.
+
+The board case list/detail pages are read-only. URL query parameters retain
+search/status/type/project filters through detail navigation; list paging and
+the `GET /api/companies/:companyId/cases/types` read use authorized server data.
+Storybook's Cases / Read-only pages stories mount those same production pages
+with HTTP fixtures, including document previews, waiting handoffs and mobile.
+
+Cases do not have a quarantine/promotion contract. Low-trust runs must save
+findings through their governed task/review path rather than write case data.
+Historical low-trust case provenance also blocks automatic execution context
+and handoffs; operator reads remain available for review. Skill-test runs omit
+workflow context to preserve their task-only scope. Cancelled or unapplied
+handoff intent is history, not an incoming phase instruction.
+
+Focused verification lives in the case route, handoff service, native handoff,
+durable admission, and legacy process integration tests. Run the explicit-only
+case-handoffs Product E2E workflow for provider/browser qualification; fixture
+and service tests do not establish that a live model followed the workflow.
+See [implementation and acceptance](plans/2026-10-19-persistent-case-handoffs.md)
+and the [agent case reference](../skills/paperclip/references/cases.md).

 ## 6. Architecture
 
+### Experimental persistent cases and handoffs
+
+Standalone cases (`enableCases`) are independent of the experimental pipeline
+case model. A passive case has no execution requirement. `work_issue_id` binds at
+most one primary ordinary task per case and one primary case per task. Handoffs
+reuse that task, update its assignee through normal task policy, and store a free
+text phase separately from case/task status. They do not satisfy review gates.
+
+Native `create_case` requires `kickoff` and `workflow_document_text`, delegating
+to ordinary case handoff acceptance. New-case API handoffs also require workflow
+text. It is saved verbatim as ordinary task document key `workflow`, title
+`Workflow`, format `markdown`. Missing or blank text is rejected before mutation.
+Top-level `initialDocuments` belongs to first-task kickoff: normalized, unique
+task document keys, at most 20 additional documents and 200,000 total body
+characters including the workflow. Its key is reserved from additional seeds.
+The acceptance transaction writes
+ordinary task documents, attribution and activity before durable wake delivery.
+Retries share the kickoff receipt and cannot repeat document revisions. Existing
+primary tasks, binding existing tasks and terminal handoffs reject initial
+documents. There is no passive native creation branch or document seed storage. Native case-document
+tools are retired; case detail and execution context roll up authorized task
+document references, omitting bodies and system keys. Historical case document
+storage and REST reads remain compatible.
+
+Starting the first new task of an existing passive case also requires workflow
+text. New-case binding may create `workflow` on the bound task with ordinary task
+mutation authority and create-only revision semantics; an existing key conflicts
+atomically. Later handoffs of an existing primary task omit workflow text and
+revise it through ordinary task document tools. Existing stored cases are not
+backfilled. Receiving agents are instructed to read the task's workflow document;
+its authorized metadata precedes the document reference budget, while its body
+is read on demand. Recommend both a Mermaid `stateDiagram-v2` map and prose
+defining each transition's trigger, evidence, destination agent, human wait/resume
+rules, and correction/escalation limits. State IDs match phases and named edge
+outcomes are defined in prose. No graph parser, guard interpreter or new workflow
+execution service is added.
+
+`case_handoffs` is a durable, principal-idempotent intent/delivery ledger.
+Acceptance atomically stores the comment, links, observed revisions, audit, and
+delivery identity. A running source yields; it retains execution ownership until
+provider termination and workspace/session settlement are proven. Its late
+mutations cannot complete transferred work. Delivery uses the ordinary wake queue
+with a stable receipt, preserving Stop, private access, responsible-user, pause,
+and budget rules. A queued receipt is not proof that the recipient ran.
+Whole-company deletion removes cases and their history before tasks and agents.
+Permanent deletion of an individual agent with retained handoff history returns
+`409 agent_case_history_retained`; keep that agent terminated to preserve attribution.
+
+An existing case with a primary task may instead receive `to: "done"`.
+This terminal handoff records `awaiting_completion`, keeps assignment and
+execution unchanged, and returns `callerMustYield: false`. Normal task
+completion remains authoritative: accepted transition to `done` atomically
+closes the case, sets its phase to `done` and records the handoff as `completed`.
+A task already done settles immediately. Reviews, questions and other legitimate
+waits do not close the case. Stop, task cancellation and reassignment cancel
+the intent. Recording a terminal intent cannot manufacture completion evidence
+or bypass review. Ordinary task completion without this intent leaves case
+status unchanged. Settling an admitted intent remains available while cases
+are disabled, like outgoing-execution cleanup.
+
+`case_access_sources` retains existing task/project boundaries. All sources must
+remain readable; unlinking or deletion cannot widen access. The same policy covers
+case contents, documents, revisions, annotations, assets, history, audit, and live
+publication. Agents cannot supply creator or responsible-user overrides.
+
+The REST operation is `POST /api/companies/:companyId/case-handoffs`; native agents
+use `handoff_case`. History, retry, and cancel stay on the case. Workflow routing
+lives in prompts/skills, without a server-configured phase graph. See
+[persistent case handoffs](plans/2026-10-19-persistent-case-handoffs.md).
+
+Native standard-mode agents also have `create_case`, `read_case` and
+`update_case`. Reads and updates default to the task's primary case and preserve
+the standalone-case authorization, provenance and audit rules of REST. Case
+updates expose facts only; routing, status and permissions remain outside those
+updates. Update receipts deduplicate identical keys within one admitted run;
+creation and handoff receipts remain principal-scoped. Ordinary `read_document`
+and `write_document` manage the active task's revisioned documents.
+
+`read_case` keeps small responses structured. Large responses return bounded
+`readPage.text` JSON chunks with case/task routing versions on every page. Use
+`section: "fields"` to retrieve the entire fields object, including large keys,
+strings, and arrays. Continue with the same `section` and `snapshot`, passing
+`offsetBytes: readPage.nextOffsetBytes` until it is null; concatenate the text
+before parsing JSON. A 409 means facts, accessible references, or routing changed:
+restart at offset zero without the old snapshot. Each page reauthorizes current case access through
+`GET /api/cases/:id?agentRead=true`; no generic API tool or asset grant is needed.
+`limitBytes` is 4–8192 UTF-8 bytes. Ordinary REST reads retain their existing full
+response, and ordinary `update_case` mutation receipts remain unchanged.
+For `section: "document"`, require `documentKey` and optionally
+`documentIssueId`. Omit the task ID for historical case-owned documents; a
+supplied ID must identify the case's primary or currently linked task. Return
+the selected document as bounded JSON pages. Recheck source access, linkage,
+and document trust on every page, and reject system or quarantined documents.
+Document identity, revision and body participate in the snapshot. These reads
+work without generic API tools and confer no additional mutation authority.
+
+Case context is authorized on each admission. Fresh sessions receive a bounded
+snapshot; verified native continuations send current routing metadata and new
+handoff instructions, plus case facts when their content or document revisions
+change. An incompatible or unproven prior projection falls back to full context.
+This limits repeated input without treating prepared database snapshots as proof
+that a provider received them.
+
+The existing Cases navigation opens read-only list and detail pages. List filters
+are URL-backed and applied before authorized pagination. A distinct-types read
+uses the same case visibility policy. Rows include batched current work context;
+detail preserves document previews/revisions, attachments, references, activity
+and handoff history. No case mutation or handoff recovery controls appear there.

+contains arithmetic and receipt smoke cells for a same-task round trip among three native agents using real case/task
+APIs, saved documents, handoff receipts, and browser readback. Receipt smoke has
+an explicit terminal handoff to `done` on its fourth run, proving case closure
+through normal task completion without a fifth provider run. It also has
+an initial task-owned brief supplied at kickoff through `initialDocuments`,
+ordinary native task document reads/writes, and case-page rollup readback.
+Earlier case-document campaign results remain preserved and do not qualify

+same model and limits. The API profile uses an encrypted company-secret
+reference; the subscription profile receives only an explicitly supplied private
+login fixture. The original arithmetic cell remains subscription-only.
+The receipt cell declares exactly four task work runs, 90-second work-run limits,
+a five-minute attempt, and 100-cent accounted-work budgets. Initial agent setup
+also performs production hello probes outside heartbeat counts, budget accounting
+and the work-run usage report. Up to three initial probes are expected; their

+# Persistent cases with same-task agent handoffs
+
+## Outcome and boundaries
+
+A case is a persistent record that can exist without execution. Starting its
+workflow creates or explicitly binds one ordinary primary task. Each handoff
+reassigns that same task, preserving its thread, workspace, execution policy,
+responsible user, and each agent's own task session. Agent prompts choose phases;
+existing task and review controls decide whether execution is allowed.
+
+The implementation extends standalone `cases`, not experimental `pipeline_cases`.
+It uses the existing database and delivery coordinator. There is no graph editor,
+configured transition graph, external workflow service, or separate case assignee.
+Ordinary case and task completion remain independent. An explicit terminal
+handoff to `done` closes the case on accepted completion of its primary task.
+If a passive case retains several
+unrelated private task boundaries, automatic kickoff fails closed when a new
+ordinary task cannot preserve them; an eligible existing primary task is required.
+
+## Persistent contract
+
+Cases add `workIssueId`, `phase`, and `handoffVersion`. One task may be primary
+for one case. `case_handoffs` records authenticated intent, the expected and
+applied task revisions, instructions/comment, delivery identity, and retry lease.
+Its states are `awaiting_release`, `pending_dispatch`, `delivered`, and `cancelled`.
+Delivery means durable wake acceptance, not proof of agent execution.
+
+`case_access_sources` retains source task/project identities. Access requires the
+intersection of their existing permissions. Unlinking or deleting a source never
+publishes its contents. Lists, documents, revisions, annotations, assets, audit
+feeds, and live events enforce the same boundary. A newly started case normally
+inherits its primary task's access. Existing passive cases retain their sources.
+
+`POST /api/companies/:companyId/case-handoffs` and the live `handoff_case` tool
+share a transaction and idempotency contract. Subsequent handoffs require observed
+case and task versions. A retry with the same principal/key returns the same
+receipt, including after the source run ends. Different input under that key fails.
+
+The outgoing run yields after acceptance. The harness fences its task mutations
+and waits for observed provider exit and workspace/session settlement before
+applying assignment. Stop and later operator changes supersede pending delivery.
+Native completion represents handoff as an incomplete, server-verified yield.
+Ordinary review/approval gates cannot be satisfied by a phase name.
+
+## Acceptance matrix
+
+| Journey | Required evidence |
+| --- | --- |
+| Passive case | No task or run created |
+| Kickoff | One primary task, handoff comment, receipt, and successor |
+| Round trip | Same task through triage, implementation, verification, correction |
+| Return to agent | Fresh instructions with its compatible existing task session |
+| Duplicate/concurrent requests | No duplicate assignment, comment, or provider execution |
+| Restart | Committed intent and accepted wake recover without repeating work |
+| Source still active | Recipient waits for provider and workspace settlement |
+| Stop/stale completion | Old intent/output cannot override the winning task decision |
+| Private record | Source permissions cover all reads and copied outputs |
+| Review gate | Existing verdict/approval still required |
+| UI | Current owner and waiting recipient are distinguishable; retry failures visible |
+
+## Implementation state
+
+Work is on `codex/persistent-case-handoffs` in the existing isolated checkout.
+Schema, shared validation, migration, access policy, transactional service,
+delivery worker, runtime bindings, context, and minimal UI are implemented.
+Verification uses embedded PostgreSQL, production services/transports, actual
+process adapters, and the real native runner with a scripted Codex provider.
+Presence of implementation is not a claim that live qualification passed.
+
+## Verification evidence (2026-10-19)
+
+| Check | Observed result |
+| --- | --- |
+| Standalone case routes and shared request validation | Latest case suite 24 tests and shared validator suite three tests passed, including retained-source privacy, assets after unlink, audit filtering, pipeline fallthrough, source attribution, denied low-trust mutations and cross-company history/retry/cancel behavior |
+| Handoff service and actual legacy process workflow | Latest run 24 tests passed, including concurrent/replayed intent, worker restart/leases, accepted wake acknowledgement loss, private boundaries, disabled cleanup, HTTP source fencing, rejected recipients, cancelled instructions, skill-test scope, historical quarantine and actual-parent assignment authorization |
+| Assembled native workflow | Passed with real runnerd and scripted Codex app-server: live tool call, automatic accepted yield, actual source process retirement, same-task successor and fresh context persisted through `write_document` |
+| Native executor regression | 744 tests passed after correcting the feature-gate integration |
+| Final affected case integration | 57 tests passed across six suites after trust/scope hardening, including the actual native runner and legacy process paths |
+| Final authorization hardening | Protected/cyclic implicit parents use ordinary allowed fallback; protected retained private parents fail without partial work. Cross-company present/absent cases return indistinguishable 404 responses for history/retry/cancel. Native integration passed again after the parent fix. |
+| Runner schema compatibility | 85 strict contract/dispatch tests, 29 authority tests and four coordinator tests passed after replacing unsupported UUID format metadata with the canonical UUID pattern |
+| Startup registration | 50 affected startup tests passed; explicit durable-worker registration and signal forwarding covered |
+| Runtime queue and run controls | 26 tests passed; separate queue-module suite 25 passed, including assignment races and cancellation/feature-disable admission |
+| UI and live updates | Case detail, task cases panel and workflow section tests passed. Final live-update suite 72/72 and authenticated WebSocket suites 14/14 passed, including populated/empty task-only caches, UUID/identifier history and denied case/task access. Browser screenshot inspected from the isolated provider attempt. |
+| Repository typecheck and build | Both completed successfully twice; generated runner checks and Rust release build passed. Final affected UI typecheck/build and server build passed again after parent, route-gate and live-update fixes. |
+| Migration structure | Migration numbering/safety passed with 20 existing baseline findings; five newest snapshots retained. Direct source-to-snapshot comparison for 0357 produced zero migration statements. The separate five-second Vitest snapshot test timed out; its failure remains recorded. |
+| Token gates and capability maps | Passed; map validation covers structure, not live execution |
+| Original full `pnpm test:run` | Stopped after its general-server run recorded two 15-second timeouts (chat and file resources) and 53 native executor fixture failures. Both timed-out tests passed unchanged in isolation; all 744 native executor tests subsequently passed after the integration fix. Full-catalog verification is being repeated through the repository's supported isolated CI shards. Preserve the original invocation's failures. |
+
+The complete server catalog was subsequently exercised through all four general
+and all four serialized CI shards: 1,172 files and 25,184 tests were collected.
+Those original shard invocations were not green: 18 files failed, including
+intermediate-source UUID/schema failures, incomplete test doubles, a missing
+route authorization guard, cold-import/startup timeouts and one socket hang-up.
+Every failed server file subsequently passed a fresh focused run after the
+relevant fixes. The original failures are retained in
+`/private/tmp/case-check-server-*.log` and
+`/private/tmp/case-check-serialized-*.log`; this is not a claim that a single bulk
+invocation passed.
+
+Focused reruns preserve the original assertions and time limits. Later UI/route
+reruns use Vitest 5's supported `--fsModuleCache` and `--fsModuleCachePath`
+options to reuse validated compiler output under shared-host load. One longer
+ownership-import diagnostic was excluded from acceptance evidence; the final
+ownership/comment run passed all 267 tests with normal limits. Responsibility
+invariants passed 14/14 unchanged, device login 41/41 twice, historical questions
+33/33, agent secret bindings 9/9, connection fixtures 6/6, environment routes
+20/20, live-run routes 91/91, CLI auth 24/24, retry lifecycle 15/15 and the static
+cross-company authorization guards 2/2.
+
+All workspace projects were exercised. The fail-fast wrapper stopped before CLI
+and before the remaining adapter/plugin projects, so those were explicitly run
+with the same isolated home/config/temp conventions, two workers and compiler
+caching. No project was silently omitted.
+
+| Workspace catalog | Observed result and remaining qualification gap |
+| --- | --- |
+| UI | Original bulk run: 754 files, 8,541 tests, five failures in three files. The live-update fixture was corrected and its stronger final suite passed 72/72. Unchanged IssuesList remains 43/50 with seven five-second timeouts; AgentToolsTab remains 5/7 with import timeouts and subsequent late React cleanup errors. One isolated tree test also exceeded five seconds. |
+| Shared, catalog, adapters and plugins | All 17 projects covered: 312 files, 4,964 tests; 4,937 passed, seven failed, 20 skipped. Remaining unchanged five-second timeouts: ACPX execute four, git workspace sync one, GitHub launcher one, Grok auth copyback one. Per-project results are in `/private/tmp/case-b-recovery-RebfIL/results.json`. |
+| CLI | Full 66-file run: 533 passed, six failed, one skipped test. One bounded serial rerun of all three failed files yielded 77 passed, three failed, one skipped. Remaining failures: two large-archive five-second timeouts and worktree reseeding blocked by PostgreSQL shared-memory allocation. Import/export's test was skipped because its beforeAll server-health deadline expired, not because the capability was intentionally disabled. |
+| Database | Original 52-file run: 117 passed, ten failed, 73 skipped tests. Failures were PostgreSQL bootstrap/resource failures or time limits, with no reported schema-diff assertion. An additional serial rerun was stopped after approximately 13 minutes of rotating startup/collection probes under confirmed host IPC exhaustion; it is not green evidence. Direct schema/snapshot equality passed separately. |
+
+Full-suite qualification remains **incomplete**. The CLI PostgreSQL error was
+`shmget(size=56): No space left on device`; a read-only host check found 31 of 32
+shared-memory slots occupied while the disk had approximately 1.4 TiB free.
+No running database could be attributed to this task's logged isolated roots;
+no unrelated database, IPC object, system limit or test timeout was changed.
+The database support probe can run during module collection, before ordinary
+Vitest test/hook deadlines, so startup retries are not reliable acceptance under
+that host condition. The bounded reruns and original failures remain separate
+evidence. The serial database rerun was explicitly interrupted (exit 130).
+
+The remaining verification path is to run the standard repository checks on a
+host with available PostgreSQL IPC capacity and enough CPU for the existing
+five-second tests, then repeat the one configured-provider workflow below.
+No further rendering, archive, adapter or database retries are running.
+
+The configured-provider smoke was attempted in an isolated instance using the
+existing Codex subscription. Kickoff created case
+`bbd95339-6f8b-4cf8-b99b-f7c00585b4be` (`RUN-C1`) and primary task
+`3b6eabdd-01f9-456d-8dc6-5abcff8705b1` (`RUN-1`). Its first native run,
+`23411a41-7596-4c14-9987-513be8999c0f`, was rejected by Codex with HTTP 429
+and `responseTooManyFailedAttempts`, before completing triage. The provider
+round trip and returning-agent provider-session reuse remain **unqualified**.
+The deterministic native test is separate evidence, not a replacement claim.
+
+The retained attempt is under
+`tests/runner-e2e/results/local-2026-10-19T13-40-41-760Z/` (ignored generated
+evidence), including `snapshots/chat-final-run-ledger.json` in its attempt
+directory. Two preceding attempts stopped on test-fixture errors before
+workflow execution; redacted configuration reuse and exact-case screenshot
+admission were corrected. All attempts retain their own evidence and cleanup
+records. No operator login/config/session files are committed.
+
+To repeat provider qualification after access recovers, select only
+`case-handoffs.runner-codex-subscription.local.same-task-roundtrip`; see
+`tests/runner-e2e/README.md`. The attempt has one automatic try, a bounded turn
+count and company/agent budget stops.
+
+## Read-only case pages — 2026-10-19
+
+Implemented the approved Storybook design in the production Cases and CaseDetail
+pages. The stories now mount these pages with HTTP fixtures; there is no separate
+prototype renderer. Cases support URL search/status/type/project filters,
+No project, and authorized server paging. Detail reads saved fields, current
+work, documents/revisions, attachments, relationships, activity and handoffs;
+case mutation and handoff recovery controls are absent. Task controls and agent
+REST APIs retain their existing authority.
+
+List work context is batched, and the distinct-types endpoint uses the same
+retained-source access policy. A discovered stale-preview gap is addressed by
+scoped document/revision cache invalidation and document revision activity/live
+events. The mobile revision comparison pickers fit the dialog. Case work has a
+named landmark, and dark status-chip text has AA contrast on its tinted fill.
+
+Verification for this UI change:
+
+- 100 focused UI tests across case pages, fields, task links, revisions, activity,
+  and live updates passed. UI and server TypeScript checks passed.
+- 27 real PostgreSQL case route tests passed, covering authorized paging/types,
+  constant query count, private metadata, revision publication and attribution.
+  OpenAPI mounted-route coverage passed.
+- Production UI build, token gates, map checks and 28 catalog/map tests passed.
+- Storybook production-page search → inspect → document → return play passed.
+  List retry play passed, and the final detail accessibility scan reported zero
+  violations (31 passing checks).
+- A separate local-trusted instance from this dirty checkout, using fresh embedded
+  PostgreSQL and production HTTP routes, was driven from Cases navigation through
+  No project, search, case detail, current document, two stored revisions, and
+  return with filters retained. Closing the document restored focus. At 390px,
+  the built production UI had no page overflow and both Diff pickers were visible;
+  the case detail contained no editable inputs. This was a record-reading test,
+  not provider-execution qualification.
+
+The disposable acceptance case was CAS-C1 (`3f733ea1-cd9b-4413-b80b-4ae099e38e95`),
+primary task `ec7b291e-3fee-49d3-b0b6-3d04188f18b3`. Local launch/doctor records
+are in `/private/tmp/paperclip-cases-ui-proof-v2-20261019/`; screenshots are in the
+Codex visualization workspace for this chat. Repo-wide checks/provider smoke
+were not repeated for this UI iteration; their earlier limits remain recorded
+above. No production data or deployment was changed.
+
+## Small receipt acceptance workflow — 2026-10-19
+
+Added the explicit-only Product E2E cell
+`case-handoffs.runner-codex-subscription.local.receipt-smoke`. It routes one task
+through triage, builder, verifier and returning builder. The first saved receipt
+is `{total:6}`; the verifier saves `{totalCorrect:true,missing:["currency"]}`;
+the returning builder reads the review and creates receipt revision two with
+`{total:6,currency:"USD"}`. The task completes while the case remains draft.
+Two passive cases support browser filtering. The independent oracle checks
+document/run attribution, nonoverlapping runs, delivered routing revisions,
+fresh context, native tool receipts, idempotent kickoff and browser readback.
+Read-before-write proof uses correlated production-redacted API request hashes;
+raw API arguments and bodies remain redacted in run events.
+
+Bounds are four task work runs, daily role caps 1/2/1, one concurrent run,
+90 seconds per run, low reasoning effort, one five-minute attempt and configured
+100-cent company/agent budgets. Production setup also performs small hello
+inference outside heartbeat accounting. Its tokens/cost are unavailable and are
+not zero. Setup is observed serially with a 45-second readiness deadline and
+immediate failure on lifecycle errors; cleanup pauses agents. This is not an
+absolute four-inference or dollar cap.
+
+Retained live attempts, both with automatic retries disabled:
+
+- `tests/runner-e2e/results/local-2026-10-19T17-04-22-166Z/`: fixture setup race
+  left triage verifying/paused and its work run queued. It was stopped before
+  any work execution. Setup hello calls may have occurred/retried and their
+  usage was not measured. Removed the redundant configuration PATCH and added
+  readiness admission before kickoff.
+- `tests/runner-e2e/results/local-2026-10-19T17-11-06-380Z/`: all three agents
+  became ready; kickoff and replay created one case/task/handoff. Case
+  `1f44b430-e930-4275-9196-bb2f45dccd40` (`RUN-C3`), task
+  `591ce311-59bd-4638-9174-abf342ab33ec` (`RUN-1`), native triage run
+  `62cafab4-ac88-423a-b11a-8f239221be6e`. The first work turn was rejected with
+  HTTP 429 / `responseTooManyFailedAttempts`; it ran about ten seconds and the
+  browser attempt lasted 35 seconds. Cleanup passed. Token/cost coverage is
+  unavailable. No receipt or review was produced.
+
+The second attempt also failed the persisted-home exact-secret scan on a local
+Codex rollout file. The guard's failure remains the machine result; its standard
+report is in that campaign's `merged/index.html`. The underlying HTTP 429 is
+retained in Playwright evidence. The matched category cannot be determined after
+normal temporary-home cleanup: structured login matching includes identity
+metadata as well as credential tokens. No raw rollout was published; publication
+manifest leak/missing lists are empty. Do not exempt rollout files or interpret
+this as a successful provider qualification. Future investigation should retain
+nonsecret match-category attribution with synthetic canaries before any further
+live attempt.
+
+These attempts used the dirty checkout based on
+`023f4a5d0cd452c540ddd0deb4a0b81ef5e2ff92`; their original source fields are null
+and their own definition digests remain retained. The stricter redacted
+read-before-write oracle was calibrated afterward and has not been live qualified.
+Focused final support checks passed 294 tests, including 119 receipt calibrations;
+runner E2E TypeScript, exact-cell discovery and map/diff checks passed. Broader
+support verification encountered an unchanged macOS filesystem watcher test
+(`remote-native-fixtures.test.ts`, transient create/delete mutation count zero),
+which still failed on a serial unrestricted rerun. No repo-wide build/test pass
+is claimed for this test-only iteration; earlier feature qualification limits
+remain above.
+
+### Provider-free browser acceptance
+
+`tests/e2e/cases-read-only.spec.ts` passed against the shipped production UI,
+fresh embedded PostgreSQL and public APIs: 2.8 seconds for the journey and
+23.4 seconds including server startup. It creates three passive cases, an
+unassigned reference task and two receipt revisions. Chromium enters Cases
+through the visible sidebar, filters by project/status/type/search, opens the
+record, reads both revisions, closes with Escape and restores focus, returns
+with filters intact, reloads and checks a 390px viewport. Before/after API
+snapshots are equal; no browser case mutation, agent or heartbeat run exists.
+Teardown restored the feature flag and archived the disposable company.
+
+Accepted fixture company: `e69d3f47-e17f-46d2-baf7-fb118962349d`; receipt case:
+`35d46e8a-4ca6-475d-a7e2-8a204b858e73` (`REA-C1`); reference task:
+`90c82519-ac43-45ff-9d67-cfc3e663c8ae`. The standard Playwright report is
+`tests/e2e/playwright-report/index.html`, with three screenshots and the full
+unchanged-state proof attached. This test makes no inference calls. It proves
+record browsing and persistence; it does not replace the failed live handoff
+qualification above.
+
+Three preceding browser fixture failures are retained under
+`/private/tmp/cases-read-only-browser-{first,second,third}-attempt/`: the empty
+dashboard opened onboarding, missing distinct case keys caused an upsert, and
+the latest-revision label joined its number to “latest.” The fixture now enters
+through Tasks, uses explicit keys and matches the actual accessible revision
+names. Independent bounded `afterEach` cleanup preserves the original journey
+error instead of masking it on timeout. No product/API behavior was changed to
+make these assertions pass.
+
+### Provider failure diagnosis and API recovery
+
+A read-only probe of the same bundled Codex 0.160.0 client confirmed
+`ordinaryUsageAllowed:false`, weekly usage 100%, with a reset of October 24 at
+9:14 PM America/Chicago. Both `gpt-5.6-sol` and `gpt-6.1-sol` are available;
+unsupported model selection was not the cause. Only initialize,
+account/rateLimits/read and model/list ran, with no inference. The isolated
+credential copy was removed. Sanitized evidence is retained in
+`tests/runner-e2e/results/case-receipt-recovery-2026-10-19/subscription-quota.json`.
+
+The user supplied an API credential source; only `OPENAI_API_KEY` was loaded
+privately. Its model catalog includes the unchanged `gpt-5.6-sol`. Added
+`case-handoffs.runner-codex.local.receipt-smoke` using the existing encrypted
+company-secret fixture. The subscription cells remain distinct; the historical
+arithmetic cell was not extended to API authentication. API roles preserve their
+secret references instead of applying subscription-home overrides.
+
+The first API attempt, `local-2026-10-19T17-44-00-385Z`, completed four successful
+nonoverlapping native runs and passed all eleven independent workflow checks.
+Case `f5a67014-69fe-42be-b28c-53fef3b4e9c8`, task
+`fcbe7093-10fc-4fa4-a757-4bf793ff2906`. It then failed an ambiguous browser
+locator: “verification” matched the phase and a sender's agent name. That failed
+grade remains retained. The selector now matches the exact phase descendant;
+handoff counting uses the outer history list. Credential scanning, artifact
+publication checks and cleanup passed. Its temporary private home was removed
+after packaging; retained evidence contains no raw credential/session files.
+
+Secret-scan diagnostics now label only safe source fields (for example,
+`CODEX_AUTH_JSON.tokens.account_id` versus `access_token`) and preserve the
+original run failure in a sanitized `persisted-state-scan.json` snapshot. No
+scan exclusions or failure gates were relaxed. Synthetic identity/token canary
+and streamed-file tests verify the new labels without printing matched bytes.
+The original subscription scan match remains unclassified because its raw
+temporary file had already been removed; the separate API attempt passed the
+same persistence gate.
+
+The selected packaged runner is darwin-arm64, SHA-256
+`56b31bc48d0d9dfd7a3239e6275d6501e7b41b331553cc9d495936d3898c2e12`, built
+October 19 at 9:22 AM Chicago; the server copy is byte-identical. It contains
+the case-handoff continuation contract. Final focused support verification:
+552 tests passed across 20 files; runner E2E TypeScript and three-cell discovery
+passed. These checks do not erase earlier broad-suite limitations.
+
+The second API attempt, `local-2026-10-19T17-50-06-954Z`, passed all eleven
+workflow checks and its browser journey in 166 seconds. Its machine grade
+remains failed: the new special-case harness branch omitted the canonical
+`final-state.png` and `snapshots/api-state.json` required by evidence packaging.
+Credential scanning, publication checks and cleanup passed; its private home
+was removed after preserving sanitized evidence. The case-handoff branch now
+captures the verified final task page and saves allowlisted current task,
+case and run facts with matcher results. Packaging requirements remain intact.
+Runner E2E TypeScript and 444 focused checks passed after this fix.
+
+### Live receipt acceptance
+
+The final API attempt, `local-2026-10-19T17-56-25-856Z`, passed the complete
+Product E2E cell: four real native Codex task runs, eleven independent workflow
+checks, browser list/filter/detail/document revision assertions, evidence
+packaging, exact-secret scans and cleanup. Journey duration was 129,998 ms;
+Playwright including isolated server startup took about 2.5 minutes. No automatic
+retry ran. The standard report command also passed for the exact selected ID.
+
+- Company: `a1f612d7-f7c1-425a-8ec0-5622d3a6fc1f`.
+- Case: `0b6f65c0-dfe5-4c67-af64-4b84813aadde` (`RUN-C3`).
+- Primary task: `ed97f870-0fde-431f-85e2-aee8a69c9afb` (`RUN-1`).
+- Runs in phase order: `946d827f-3e4e-42b8-add4-2448ad201580`,
+  `342e8f7f-22e9-4d01-b7ad-d9804cdfd840`,
+  `101ac7d3-1ddb-4b28-9f32-f521b497e5c8`,
+  `7f67bc5e-8bb7-4ede-a702-a9ad4a23c60a`.
+- Final receipt revision 2: `{"total":6,"currency":"USD"}`; independently saved
+  review: `{"totalCorrect":true,"missing":["currency"]}`.
+- Task is `done`; case remains `draft`, phase `revision`, version 4, with no
+  pending handoff. All four handoffs reference the same primary task.
+- Report: `tests/runner-e2e/results/local-2026-10-19T17-56-25-856Z/merged/index.html`.
+
+The published evidence manifest has no leaks or missing files and includes both
+canonical final artifacts. The disposable credential/server/database home was
+removed. Earlier failures above remain retained with their original grades.
+This qualification used the API profile; it does not resolve the exhausted
+subscription profile or retrospectively classify its original secret-scan match.
+
+Work-run usage coverage is four of four runs: 153,541 input tokens, 3,981 output
+tokens, and 660,979 cached input tokens (818,501 total). Production context,
+rather than the tiny receipt payload, dominates tokens. Provider dollar cost is
+unpriced and setup hello usage remains unavailable; zero reported dollars must
+not be interpreted as free inference. Use the provider-free browser test for
+routine UI iteration and this four-turn cell for occasional live acceptance.
+
+### Terminal destination amendment
+
+The user requested a prompt-level `handoff_case` destination of `done` to close
+the case. This supersedes the initial agent-only destination restriction.
+Existing agent handoffs retain their input and yield/delivery semantics.
+An alternative `to: "done"` accepts only an existing case with a primary task,
+the two observed versions, principal idempotency and final instructions. It
+records `destinationKind: done`, no recipient and `awaiting_completion`, without
+yielding or changing task status/assignment. Normal completion remains required.
+Task completion and terminal case closure settle together in the ordinary
+issue-service transaction, including native accepted completion. Review and
+human waits preserve the intent. Reassignment, Stop and task cancellation
+invalidate it. Disabling cases blocks new requests but permits admitted intent
+to settle during normal task completion. Ordinary completion without intent
+continues to leave cases unchanged. Passive cases retain their existing CRUD.
+
+| Required outcome | Verification owner |
+| --- | --- |
+| Strict union contract, old input compatibility, durable migration | Contract/schema worker |
+| Authorized idempotent request, no assignment or wake, current versions | Handoff service worker |
+| Normal completion closes atomically, legitimate waits remain open | Runtime worker |
+| Stop/reassignment/rollback and native non-yield behavior | Runtime worker |
+| Read-only pending/completed history and current context/guidance | Root |
+| Four real native turns ending with a fifth terminal ledger entry | Root |
+
+Historical reports above retain their original grades and earlier case-draft
+contract. New acceptance must use the revised definition digest and report.
+
+Terminal implementation verification: shared contracts 12/12; runner contracts
+106/106; capability inventory checks 4/4; real-PostgreSQL application service
+41/41; runtime/Stop/lifecycle regressions 37/37; native assembled completion
+and other focused runtime checks 15/15; existing legacy handoff/heartbeat
+checks 8/8; read-only UI 16/16; Product E2E support/oracle selection 497/497.
+Workspace-wide typecheck and build passed; server typecheck passed again after
+the final Stop fix and public request-input type correction. Token gates,
+migration checks, five-snapshot retention, map checks and Storybook catalog
+generation passed. The full repository test command is tracked separately below.
+
+Independent review caught a Stop-versus-acceptance gap: intent cancellation
+previously committed before source writes were fenced. Stop now records
+`executionCancellation: requested` under the same task/run locks and transaction
+as cancellation. Real database races for agent and terminal destinations prove
+that a fresh handoff cannot be accepted in the process-termination gap. A later
+review found no remaining blocker in those inspected paths.
+
+Terminal live acceptance passed in campaign `local-2026-10-19T19-14-18-642Z`:
+four real native Codex work runs and eleven independent workflow checks, including
+the new terminal receipt, plus production browser readback, packaging, secret
+scans and cleanup. Journey duration was 163,229 ms; Playwright with isolated
+server startup was about 3.9 minutes. No automatic retry or fifth run occurred.
+Company `4f479fd6-c780-49d2-8709-4f7d8c4f1830`, case
+`95584a08-2a0c-4b21-970d-48cf583ad32c` (`RUN-C3`), primary task
+`eacd82f3-56f8-409b-b6e9-dee36682ae50` (`RUN-1`). Both case and task are done;
+case phase is `done`, version 5, and no handoff remains pending. Terminal
+handoff `bae80098-30d0-41e7-b6d4-e47955307dd2` and case share completion time
+`2026-10-19T19:17:56.884Z`. Standard report generation passed:
+`tests/runner-e2e/results/local-2026-10-19T19-14-18-642Z/merged/index.html`.
+The manifest contains no leaks/missing evidence, and the private test home was
+removed. Work-run usage: 166,022 input, 4,236 output and 842,772 cached input
+tokens. Dollar cost is unpriced; setup probe usage remains unavailable.
+
+The full `pnpm test:run` invocation was started in this iteration and remains
+separate from those completed checks. Its live log is
+`/private/tmp/case-done-workspace-tests.log`; it was still running the serial
+general-server group after terminal live acceptance. No full-suite pass or
+PR-ready qualification is claimed from this partial repository run.
+
+### Completed-task pause notice correction
+
+The terminal live report above exposed a UI defect despite passing the workflow
+oracle: a manually paused assignee displayed a warning and Resume action on a
+task already marked done. The report's canonical final screenshot follows fixture
+retirement, but the earlier task capture also has the warning; retained evidence
+does not establish when that earlier pause became visible. Existing reports and
+grades remain unchanged.
+
+The shared paused-assignee notice now receives task status and hides for done
+or cancelled work in both task interfaces. Reopening restores the warning while
+the agent remains paused. No agent lifecycle or permission behavior changes.
+The real receipt journey now rejects this warning before its final task capture.
+Focused chat regression tests pass (329/329), UI and runner-E2E typechecks pass,
+and token and map checks pass. A separate provider-free browser journey exercises
+real APIs, persisted status changes and both production task interfaces; its
+evidence is recorded separately from paid workflow acceptance.
+
+Provider-free browser verification passed in both interfaces (2/2), including
+done → todo → cancelled → todo → done. Status, assignee controls and composer
+finish loading before absence assertions. Both fixture agents stayed manually
+paused and each company retained zero heartbeat runs. Root inspected the
+completed and reopened task screenshots. The independent read-only review found
+no actionable issue. Report:
+`tests/e2e/test-results/terminal-paused-agent-2026-10-19/report/index.html`.
+
+### Native case tools and continuation context
+
+Added production `read_case`, `update_case`, `read_case_document` and
+`write_case_document` for standard native runs with cases enabled. Omitted case
+IDs resolve the primary workflow case; explicit IDs resolve only authorized
+standalone cases. Fact updates expose title, summary and whole-object fields,
+excluding status, routing and permissions. CRUD retry receipts are scoped to
+the admitted run; handoff replay remains principal-scoped. Both dedicated tools
+and REST retain ordinary permissions, source trust, attribution and revisions.
+
+The native adapter reuses real authenticated routes. Case read/update selects
+document metadata in SQL; default REST/UI responses remain compatible. Explicit
+document reads accept the existing bounded 200k-character document schema,
+including JSON escaping, through a server-only 4 MiB inline allowance. The
+model receives the body once. Generic API inline limits remain unchanged.
+Stop/handoff fencing and copied-source retention now share the case write
+transaction. Large captured case responses retain both case and run-owner
+boundaries; revoking a retained source cannot leave a readable captured asset.
+
+The previous description that full context reaches the provider on every wake
+was too broad. Ordinary verified native continuations already used event deltas;
+case handoffs previously used the full prompt again. Native case continuations
+now carry fresh identity, phase, versions, read paths and new instructions, with
+facts only when their fingerprint changes. The fingerprint covers summary,
+fields, document revisions and accessible references. It excludes routing and
+history changes. Proof comes from the actual admitted native input and exact
+company/agent/task/session/base-run identity, not merely a prepared snapshot.
+Cold, reset, unknown-format and failed-resume paths retain the full snapshot.
+Authorization still refreshes each admission, and provider history still grows
+by one new message per phase. Legacy adapters retain their existing snapshot.
+
+Deduplication preserves edited messages and deletion tombstones. Only identical,
+nondeleted source text already represented by the current projection may be
+omitted. Deleted source comments produce explicit withdrawal guidance rather
+than reusing their retained old instruction body.
+
+Deterministic actual model-envelope JSON sizes with an 8 KiB case field:
+10,276 bytes cold, 1,085 bytes unchanged resumed, 9,462 bytes after changed fields
+and document revision. These are input bytes, not token or dollar measurements.
+Verification: 210 runner contract tests and generated-output checks, full runner
+build/vendor refresh, 85 focused continuation/projection tests, 42 real-database
+case tests, API/HTTP tests (2,055), additional route/capture/assembled native
+checks (40), redaction tests (10), and receipt support tests (128) passed. The
+final body-alias cleanup passed its real HTTP suite (8) after the live smoke
+server had loaded the preceding helper; that final cleanup is not independently
+qualified by the concurrently running provider attempt. Workspace typecheck and
+build passed.
+
+Broad verification limits remain explicit. The restricted E2E support run had
+40 failures from local process/socket restrictions. The unrestricted run passed
+2,911/2,916 tests; four installed-CLI checks rejected inherited NODE_PATH and all
+14 checks in that file passed with a clean direct-Node environment. The remaining
+unchanged filesystem-watcher test failed independently of the application:
+raw node:fs.watch on this Darwin host delivered no events, even for a persistent
+file over two seconds. No observer check was weakened. The earlier full
+repository suite was stopped as superseded while still incomplete, preserving
+`/private/tmp/case-done-workspace-tests.log`; no full-suite pass is claimed.
+
+The new native-tool live campaign `local-2026-10-19T19-57-00-135Z` passed all
+12 independent checks in one attempt with four real `gpt-5.6-sol` runs on the
+same task. Triage persisted `inputsValidated`, implementation saved the receipt,
+verification independently found the missing currency, and returning
+implementation saved revision 2 (`{"total":6,"currency":"USD"}`) before terminal
+handoff closed the case and task. Browser readback, report packaging, secret
+scans and fixture cleanup passed; the private test home was removed. Report:
+`tests/runner-e2e/results/local-2026-10-19T19-57-00-135Z/merged/index.html`.
+Company: `010427e2-38cf-460a-a965-7856f1552bad`; case:
+`f2b7c609-8ca0-4ca7-a687-6e4f42a5e829` (`RUN-C3`); task:
+`df01ea0e-3007-4428-b171-d662a120027f` (`RUN-1`). The work runs reported
+133,781 input, 3,101 output and 521,496 cached-input tokens, with usage coverage
+for all four runs. These are recorded provider usage categories; the report
+does not establish an invoiced dollar total.
+
+This attempt used fresh provider sessions for all phases, including returning
+implementation. Its saved task-session row lacked the effective configuration
+fingerprint, so normal compatibility validation correctly reset it. Audit found
+the handoff early return in run completion skipped ordinary session persistence.
+The live pass therefore proves tools and workflow behavior, while compact
+returning-session behavior requires its separate deterministic evidence and the
+session-persistence correction; do not describe this campaign as live proof of
+compact resumption.
+
+The correction reuses the ordinary runtime/session persistence block before
+releasing an accepted handoff. It stores the source agent's returned session,
+effective configuration fingerprint and source run identity; ordinary completion
+retains its prior ordering. Missing or incompatible metadata still resets the
+session. No session or authority crosses agents, and no compatibility rule is
+relaxed. The assembled regression now follows A → B → A and a later same-agent
+phase, distinguishing B's legitimate fact/document changes from unchanged facts.
+Its initial run passed all 27 completion tests but failed the new return path
+because the scripted provider reused a static settled turn ID. The runner
+correctly failed closed. The fixture now emits unique turn identities and
+preserves the resumed thread identity; production protocol checks are unchanged.
+The original failure log is retained at
+`/private/tmp/case-handoff-session-persistence-tests.log`.
+
+The strengthened fourth-phase test then exposed a separate production gate:
+its valid new handoff remained `pending_dispatch` with `wake_not_admitted`, and
+its wake receipt was `skipped` for `issue_rewake_throttled`. Two previous
+successful case phases had no issue-scoped progress activity, and an
+agent-authored instruction comment made the generic no-information throttle
+classify the new phase as a repeated wake. The diagnostic record is retained at
+`/private/tmp/case-handoff-session-roundtrip-diagnostic.log`.
+
+The queue now exempts only a validated durable case-handoff request from that
+generic cooldown. The receipt is checked against the persisted company, task,
+recipient, preallocated wake ID and assignment version, and revalidated under
+the admission transaction lock. It is not accepted by public wake schemas.
+Budget, pause, permissions, task guards, source release and duplicate admission
+remain authoritative; ordinary agent-comment throttling remains unchanged. No
+test advances time or extends its wait to hide the incorrect classification.
+
+Final deterministic qualification passed: 27 completion-boundary tests, 30
+queue/throttle tests and the actual native A → B → A → A workflow (1/1,
+33.55 seconds). The workflow verifies persisted source session/fingerprint and
+run identity, real `thread/resume`, compact continuation envelopes on both
+returning turns, fresh changed facts, unchanged facts omitted with no original
+canary, each new instruction once, and final case/task completion on the same
+task. The native test uses the actual runner with a controlled provider; no
+additional paid attempt was made. Final server typecheck passed.
+
+An intermediate four-suite run passed the 30 queue/throttle tests and failed
+only a fixture expectation that omitted the server's authoritative handoff
+comment heading. The final assertion includes the exact heading and retains
+the once-only/content-omission checks. That log is preserved at
+`/private/tmp/case-handoff-session-roundtrip-comment-prefix.log`; final assembled
+pass: `/private/tmp/case-handoff-session-roundtrip-final.log`. These results
+qualify the subsequent session and throttle fixes deterministically without
+regrading the earlier fresh-session provider campaign.
+
+The final server build, map checks and whitespace checks passed after these
+corrections. The earlier workspace build/typecheck passed; full repository test
+qualification remains limited as recorded above.
+
+### Native creation and task-owned initial documents
+
+The subsequent product decision replaces new case-owned document work with
+ordinary task documents and a case read rollup. Existing case document records,
+revisions and REST APIs remain compatible; no migration, copying or deletion is
+performed. The separate native case-document tools are retired.
+
+Native `create_case` accepts case metadata plus optional
+`kickoff: {toAgentId, phase, instructions}` and `initialDocuments`. Without
+kickoff it creates a fresh passive record and returns no task. Its native REST
+transport uses explicit `createOnly:true`; legacy default upsert semantics stay
+unchanged. Passive receipts are run-scoped and reauthorize current case access
+before identity is returned. An interrupted HTTP response retains the existing
+safe `api_outcome_unknown` behavior rather than guessing or repeating creation.
+
+With kickoff, creation delegates to the existing principal-idempotent handoff
+service. The agent-handoff input also accepts top-level `initialDocuments` when
+creating the first primary task of an existing passive case. Keys use ordinary
+task normalization, duplicates are rejected, and limits are 20 documents with
+200,000 total body characters. Task rows, documents, revisions, attribution,
+ordinary document activity and delivery intent commit together, before any
+recipient wake. Existing primary tasks, existing-task binding and terminal
+handoffs reject nonempty initial documents; ordinary task tools own revisions.
+
+Case detail adds bounded, authorized `taskDocuments` references carrying task,
+key, revision and read-path identity. Execution context references the same
+documents without bodies. Canonical task permissions, company scope, quarantine
+and system-key filtering precede the document budget. Historical case refs
+remain distinguishable. The read-only case UI loads task documents and revision
+history through ordinary task APIs and reuses the shared revision/diff display.
+There are no editing controls.
+
+Deterministic verification passed: shared validation 25/25, real PostgreSQL
+handoff/route tests 79/79, native authenticated HTTP tests 9/9, runner contract
+tests 118/118, API/redaction tests 2,058, rollup/projection tests 27/27, UI/revision
+tests 13/13, and receipt evidence tests 148/148. The actual native runner
+A → B → A → A test passed with passive `create_case`, a seeded task brief read
+before the first transfer, ordinary task document writes/reads, compact session
+reuse and final completion. Its first fixture attempt incorrectly expected
+`latestBody` rather than the ordinary task API's `body`; the failed log remains
+`/private/tmp/create-case-native-assembled.log`, and the corrected pass is
+`/private/tmp/create-case-native-assembled-final.log`. No production read
+contract was changed to satisfy the fixture.
+
+The fresh-browser test initially omitted the ordinary task API's required
+`format` field (preserved initial report); the corrected run then exposed a
+reload filter reset. Radix's empty initialization value must not clear an
+explicit URL filter, so the existing filter component now accepts only listed
+options; explicit "all" still clears. The unchanged browser assertion passes
+after this correction. The final journey passed in 3.4 seconds against a fresh
+real API/database, including task-document preview, owner link, both revisions,
+close/focus, filter restore after reload and mobile layout. Persistence snapshots
+match before/after, with no case writes, agents or runs. Root visually inspected
+the revision preview and mobile screenshots. Final report:
+`tests/e2e/test-results/create-case-task-documents-2026-10-19/verified/report/index.html`.
+The earlier reports remain in their separate initial/final directories. The
+filter's focused UI tests passed 7/7. The initial restricted workspace typecheck
+failed on tsx IPC permission; the unrestricted rerun passed. Earlier provider
+reports remain immutable and do not qualify this subsequent ownership change.
+
+Final workspace typecheck and build passed. The first build correctly detected
+generated capability-index drift after the case guide's headings moved. Official
+generators refreshed the skill heading inventory using the real evaluation
+corpus; all 106 evaluation rows and 42 legacy aliases stayed unchanged. Two
+consecutive runner builds and normal vendor refresh passed with input digest
+`1580c44e8030`, followed by the complete workspace build. Map, token and
+whitespace checks passed. Full repository `test:run` was not repeated for this
+bounded change; the focused service/transport/runtime/UI suites above establish
+its deterministic scope.
+
+The first live task-document campaign, `local-2026-10-19T21-32-43-612Z`,
+completed all four provider runs on task `0ab67ddb-71a7-4f2c-a4d5-f255def79554`
+and closed case `571f41b0-db65-43e0-a34c-3c0dbbb41fee`. The seeded task brief,
+handoff contexts, document-read receipts, corrected receipt and final closure
+were present. The returning builder reused its persisted task session. The
+campaign remains failed (11/13): ordinary task revision responses omitted the
+stored `createdByRunId`, so the strict artifact provenance checks could not
+prove which runs wrote the receipt and independent review. The ordinary
+authorized revision read now includes that existing nullable field; it grants
+no access to run contents. This is an API projection fix, with no schema
+migration or relaxation of the oracle. The failed campaign and its generated
+report remain preserved. A new campaign must qualify the subsequent fix.
+
+The revision projection fix passed six real-database document tests and seven
+canonical route tests with the unchanged 15-second timeout. Two route tests
+timed out in the first combined run while loading the large issue router; that
+log and a longer-timeout diagnostic remain preserved. The final route-only
+confirmation loaded the router in 11.475 seconds and passed all seven tests in
+14.26 seconds. Server/shared typechecks and subsequent builds passed. Tests
+prove two real writer-run IDs survive persisted revisions, human writes remain
+unattributed to a run, and denied task reads return 404 before fetching revision
+contents or provenance. No access rule or stored data was changed.
+
+The subsequent live API-key campaign `local-2026-10-19T21-39-45-440Z` passed
+13/13 receipt checks and the real-browser journey in one attempt with automatic
+retries disabled. Its four provider runs completed on the same task
+`a0afa6e2-4595-4ff4-b66c-2dfb452afb8c` (`RUN-1`), and case
+`43c35c5a-59b9-470e-9fce-be01db8615c2` (`RUN-C3`) finished as `done`, phase
+`done`, routing version 5. Triage read the seeded ordinary task brief, the
+builder saved revision 1, an independent verifier persisted its review, and
+the returning builder read that review and saved revision 2. Both receipt
+revisions now expose their actual writer-run IDs, so strict provenance checks
+passed unchanged. The returning builder reused the first builder's persisted
+session (`01a1561c-ab86-72e3-938c-f09b945fa7b3`), with both `sessionReused`
+and `taskSessionReused` true. No overlapping or extra run occurred.
+
+The recorded workflow duration was 134.288 seconds; full isolated startup and
+browser execution took about 3.1 minutes. Recorded per-run rate-card estimates
+sum to $0.8899796; this is an estimate, not provider-reported billed cost.
+Cleanup passed. Root inspected the final task screenshot and read-only case
+document/revision screenshot. The final report is
+`tests/runner-e2e/results/local-2026-10-19T21-39-45-440Z/merged/index.html`.
+The prior failed campaign remains separately recorded; no earlier result was
+regraded. Dedicated native `create_case` itself has real HTTP and assembled
+native-runner deterministic coverage; this live campaign starts through the
+harness handoff API and qualifies seeded task documents and subsequent live
+read/update/handoff/document work, not a provider-generated kickoff invocation.
+
+### Required kickoff for native creation
+
+The user's subsequent correction supersedes the optional kickoff contract above:
+native `create_case` requires a complete `kickoff` (destination agent, phase and
+instructions). Missing, null or partial kickoff is invalid before any writes.
+Every accepted call uses the principal-idempotent handoff service to create the
+case, its first ordinary task, optional initial task documents and delivery
+intent atomically. There is no native passive-creation branch or run-scoped
+creation receipt. The newly added `createOnly` REST extension is removed;
+historical generic REST upsert behavior and existing passive records remain
+compatible. This tightens new native creation without changing migrations,
+existing data, task ownership or same-task handoff semantics.
+
+The assembled native workflow no longer creates an extra passive case. It checks
+that the provider-discovered tool requires kickoff, that only the workflow case
+exists, and that the seeded brief remains readable before the first handoff.
+Earlier reports remain evidence of the source version they exercised, not proof
+of this subsequent tightening.
+
+Qualification passed for the required-kickoff change: 118 runner contract tests,
+2,131 tests across native authenticated HTTP, API catalog, ordinary case routes
+and real-database handoffs, plus the assembled native workflow (1/1, 47.76
+seconds including setup). Invalid kickoff leaves the case/task/comment/document/
+wake/run snapshots unchanged. Valid kickoff and exact replay preserve one task,
+document revision and comment; later-run replay and revoked-access denial remain
+covered. Server/shared typechecks, two consecutive official runner builds at
+digest `951f3accb325`, normal vendor refresh, final server build, map checks and
+whitespace checks passed. No timeout changes, paid provider run, UI regression
+run or full repository suite were needed for this bounded contract tightening.
+
+### Explicit workflow document
+
+The next user decision requires exact field `workflow_document_text` on native
+`create_case` and the equivalent new-case branch of
+`POST /api/companies/:companyId/case-handoffs`. The harness persists its exact
+nonblank text as the primary task's ordinary Markdown document `workflow`, title
+`Workflow`, before delivery. Creation, initial document revisions, attribution,
+audit, comment and durable wake intent remain one transaction. Workflow text and
+up to 20 additional `initialDocuments` share a 200,000-character body limit;
+the normalized workflow key is reserved against duplicate optional seeds.
+
+Every new-case API branch requires the text, including binding an existing task.
+Binding additionally requires ordinary task mutation authority and uses
+create-only revision semantics: an existing workflow key conflicts rather than
+being overwritten. Starting a newly created primary task for an older passive
+case also requires text. Later primary-task transfers reject the field; normal
+document revision tools own edits. Existing-case binding keeps its historical
+behavior, and there is no migration or inferred workflow for existing tasks.
+Principal-scoped receipt fingerprints include the text; identical replay cannot
+duplicate the workflow revision and changed text conflicts. OpenAPI 3.0 represents
+new-case, existing-case and terminal requests as three derived strict branches so
+creation requiredness is discoverable as well as enforced.
+
+The authorized primary workflow reference is ordered before the bounded document
+budget, including when 20 other documents precede it alphabetically. Agent
+execution guidance tells the recipient to read ordinary key `workflow` before
+phase/routing decisions. Its body is not injected into every prompt. The native
+assembled fixture now reads that persisted document and the initial brief before
+the first transfer and checks that the workflow body was not duplicated in its
+bootstrap input. Process-adapter and both Product E2E fixtures supply the field;
+old recorded campaigns remain evidence of their original versions.
+
+Recommended authoring is prose plus an optional fenced Mermaid
+`stateDiagram-v2` map with stable phase IDs. Prose owns actual agent IDs, expected
+outputs/evidence, transition conditions, correction limits, human wait/resume
+rules and completion gates. The diagram is advisory; neither its labels nor
+the stored document become executable guards or privileged instructions. The
+existing Markdown renderer already supports Mermaid. No graph parser, new
+workflow service, stage registry or state-machine enforcement is added. Mermaid
+syntax: <https://mermaid.js.org/syntax/stateDiagram.html>. DOT remains a general
+graph language (<https://graphviz.org/doc/info/lang.html>); formal executable
+statecharts such as SCXML (<https://www.w3.org/TR/scxml/>) are a separate future
+decision rather than a dependency for this feature.
+
+The first assembled run after this addition passed the legacy process test but
+failed the native fixture's explicit no-body-in-bootstrap assertion. The failure
+is preserved at `/private/tmp/workflow-document-assembled-tests.log`: generic
+fresh-session history restoration excerpted all ordinary task documents,
+including the new workflow document, independently of the metadata-only case
+projection. This is an additional prompt assembly path, not a failed write or a
+lost handoff. Workflow document history now needs reference-only projection there
+as well; ordinary plan and other document history excerpts remain unchanged.
+
+That path now selects only workflow revision identity, guidance and an
+authenticated read path in SQL; it never fetches the workflow body into the
+fresh-history packet. Other document excerpts, limits, time boundaries,
+redaction/trust and cached-loader behavior stay in place. Seven real-database
+session-history tests passed, including full fresh/bootstrap and failed-resume
+envelope checks, successful resume omission, plan excerpt preservation and
+workflow-body canary absence. The unchanged assembled native assertion then
+passed (1/1, 51.15 seconds including setup): it read the workflow and brief through
+ordinary tools, transferred the same task, resumed the returning agent and
+closed the task/case normally. The earlier combined run's legacy test passed;
+its native failure remains separately preserved rather than regraded.
+
+The rest of this slice passed 80 shared/service/REST tests, 2,069 API/OpenAPI
+tests, 10 native HTTP/database tests, 119 runner contract tests, 28 case context
+tests and 154 credential-free Product E2E support tests. Exact-text database
+coverage includes CRLF, leading/trailing whitespace and literal backslash-n.
+Server/shared and Product E2E typechecks passed. Two consecutive official runner
+builds and normal vendor refresh passed at digest `906c3e56e440`, with evaluation
+rows/aliases preserved; the final server build passed after the history fix.
+Map/whitespace checks passed. No additional paid provider campaign, UI/browser
+journey or full repository test suite was run for this contract addition; the
+earlier live report does not qualify the new required field.
+
+### Workflow authoring guidance
+
+The user clarified that creation/API guidance should recommend both a Mermaid
+`stateDiagram-v2` map and prose describing the transitions, not a diagram alone.
+The field schema description, native create/handoff descriptions, execution
+prompt, OpenAPI endpoint, case skill guide and product/development references
+now use that paired recommendation. Named diagram outcomes are defined in prose
+with triggers/conditions, evidence or outputs, destination agents, human
+wait/resume behavior, and bounded correction/retry/escalation rules. State IDs
+match phase names. Native and REST examples include both representations, and
+the guide provides a transition-definition table. This is authoring guidance;
+it introduces no format parser, validation rule or server transition enforcement.
+
+Verification for this documentation/prompt-only follow-up passed: all eight JSON
+guide examples parse, 2,069 API/OpenAPI tests and 119 existing runner contract
+tests pass, official generation preserves all 106 evaluation rows and 42 legacy
+aliases, the final runner build records digest `0a9988610a7e`, and normal vendor
+refresh reuses that build. Map and whitespace checks passed. No provider run or
+full repository suite was repeated for wording and example changes.

+### `case-handoff`
+
+Start a standalone case through the agent's `handoff_case` operation or the case-handoff REST API. Open its existing case record and follow its primary task. Check that the phase and current assignee are distinct from a pending recipient. Each handoff includes a link to the same primary task; expand its history to inspect instructions. A blocked handoff shows its known reason without implying that the recipient is running. Recovery remains available through authorized APIs and existing task controls.
+
+The final agent may hand off to `done`. While ordinary task completion is pending, the case remains open and shows that it will close when the task completes. Accepted completion closes the case and records a completed terminal handoff. Review and user waits do not close it. Case pages remain read-only.
+
+Automated: shared schema tests, case route privacy tests, case handoff service/delivery tests, native lifecycle tests, and `CaseDetail.test.tsx` exercise their individual boundaries. The registered explicit-only case-handoffs Product E2E suite covers the full native journey; registration is not a live pass.
+
+Manual: hand the task through implementation, verification, and correction. Its ID, workspace, thread, and review gates must remain stable. Repeat a request and restart delivery; neither may duplicate work. Try private cases with an unauthorized actor and verify documents, assets, activity, and handoff history remain inaccessible.
+
+Force local scratch preparation to fail, then let the source adapter exit while
+a child with closed output streams continues writing. The recipient must remain
+pending until the owned process group stops; a fresh delivery worker must then
+recover the same intent without repeating the source run. Create terminal intent
+from the board and stop the current execution, including a pending native retry:
+later task completion must leave the case open. Repeating Stop for an older run
+must preserve a newer execution's terminal intent.
+
+With generic API tools disabled, use native `read_case` to open a historical
+case document and a linked task document using `section: "document"`,
+`documentKey`, and the linked task's `documentIssueId` where applicable. Recover
+the full body through bounded JSON pages. Edit the document between pages and
+verify a snapshot conflict; unlink the task or revoke source access and verify
+further reads fail. System and quarantined documents must remain inaccessible.
+
+While a transfer awaits source release, change its recipient's assignment policy
+or revoke the caller's assignment grant. The worker must retain the pending
+handoff without changing the task owner or phase or waking the recipient. Restore
+the permission and verify that the same receipt can proceed without duplicate
+comments or tasks. Internal authorization context must not appear in public
+history, retry, or cancellation responses.
+
+In Cloud, verify that a stack owner with owner elevation enabled can complete a
+permitted delayed transfer. Disable that setting or change the current stack
+role before release, then verify that the transfer observes the new authority.
+An unavailable portfolio lookup must leave the transfer pending for recovery.

+Three agents use four bounded runs to save, review, and correct a tiny case receipt

State IDs should match phase names. The diagram is advisory and the server does not parse or enforce transitions. Optional initialDocuments seeds other ordinary task documents only for a newly created task; the workflow key is reserved and the combined seed text limit is 200000 characters. For an agent handoff, after callerMustYield is true, end the turn immediately: the harness starts the recipient after your execution settles. Do not finish the task or create a replacement task for another agent phase. For to: 'done', phase defaults to 'done', both observed versions are required, and no agent, new case, or task binding is accepted. A done receipt does not complete the task or yield execution: call finish_task normally with truthful completion evidence.
