-The following is an implementation plan, not a claim of shipped acceptance.
+The following remains the acceptance contract. The source proposal now connects
+the exact `source_session_v1` requester profile to an existing private Codex
+project conversation through these owners. It preserves the original Session,
+native thread and null Goal, and uses a per-Turn response schema on resumed
+threads instead of requiring new dynamic tools. File/SQLite integration uses
+the production source, request, FIFO, revision and return owners with a scripted
+model transport. Packaged browser evidence qualifies the local management
+journey only; legacy requester profiles, other executors, installed provider
+delivery and natural receiver adoption remain unqualified. See the
+[operator and recovery contract](../../reference/original-project-collaboration.md).
+This is proposed behavior, not a claim of shipped acceptance.
+
+Accepted corrections use revision/digest-bound continuations in the same FIFO,
+including after the original conclusion has been read. Queue-write recovery and
+saved-answer recovery reuse that revision without another model call; the first
+Turn and its result remain historical. The panel selects the current revision's
+state rather than presenting an older conclusion as its pending result.

+# Packaged original-project collaboration inspection
+
+All content is synthetic. The candidate uses the packaged Chat frontend and
+its real local HTTP, source, binding, FIFO, revision and result owners. Only
+provider identity observations and model transport are scripted.
+
+The primary question is “Which source may enter this original conversation,
+and what actually happened to its requests?” The default view separates
+received requests from explicit source grants. Details reveal the full brief,
+constraints, inputs, decision and conclusions. Desktop inspection includes
+queued, running, failed and returned requests together; narrow inspection
+retains a long expanded purpose and context in the dialog's scroll region.
+The 390-pixel viewport has no horizontal overflow.
+
+- [Before: original header without the collaboration action](before-desktop.png),
+  built from the baseline frontend.
+- [After: mixed request states and explicit grant](after-desktop.png).
+- [After: expanded long content at narrow width](after-narrow.png).
+- [Unavailable: retained grant can still be revoked](unavailable-desktop.png).
+
+The unavailable case closes only the synthetic original Session through its
+store owner, then rereads the panel and revokes its retained grant in the UI.
+The background Goal sidebar's status error is a separate fixture limitation:
+the lifecycle-only source profile does not qualify generic portfolio status.
+These views do not certify that sidebar, installed App/provider delivery,
+natural model adoption or model quality.
+
+## Corrections after an answer
+
+The same synthetic SQLite/HTTP/FIFO fixture first completes and reads an
+original answer, then accepts corrected source material. The old frontend
+labels that current request as already read; the updated frontend selects only
+the current revision's result and queue state.
+
+- [Before: historical read presented as the current state](correction-before.png)
+  (1440-pixel desktop, previous frontend).
+- [After: the correction is queued in the original conversation](correction-after.png)
+  (1200-pixel desktop, updated frontend).
+- [Expanded corrected request at 390 pixels](correction-narrow.png), with 16px
+  prose and no horizontal overflow.
+- [Current and historical conclusions after execution](correction-result.png)
+  (1440-pixel desktop). The existing disclosure retains both revisions.
+
+The current request and independent result stay separate from the explicit
+source grant. Escape closes the reader and returns focus to its original
+collaboration button. Expanded content uses the existing scrolling region;
+the long brief remains complete. Model transport is scripted, and the
+background portfolio/proposal read failures are retained fixture limitations.

+# Original project conversations as collaboration recipients
+
+This source proposal connects an exact registered requester to an existing
+private Codex project conversation. Its Goal stays null; the same Session,
+executor, native thread and FIFO process both human and peer input. It extends
+the existing collaboration and native Chat owners, with no new capability,
+queue, database or external-message permission.
+
+## Enable and inspect
+
+Open the original project conversation in the App and choose **Collaboration
+requests / 协作请求**. Select the original source request, inspect its purpose,
+then choose **Allow this source / 允许此来源**. The grant identifies the source
+Goal lifetime, requesting Agent, parent request and verified original recipient.
+An existing workspace grant or `all_registered` delivery scope does not enroll
+this recipient kind.
+
+The panel shows received work, its queue state, current brief and revision,
+independent receiver decision and returned conclusions. Expand a request for
+constraints, actual input references, acceptance and return requirements.
+“Conclusion awaiting requester” means a result for the current revision exists; “Read by requester” means
+the original requester read that result. Neither proves requester adoption.
+Peer input is labelled **Collaborator**, and its visible message is the request
+purpose; execution instructions remain outside the human transcript.
+
+Choose **Revoke / 撤销** to disable that source-to-recipient grant. Retained
+grants remain revocable when the original connection is unavailable. Restore
+the original App, operator, project and executor connection before retrying
+discovery or execution. Revocation stops new dispatch; it does not erase history
+or roll back already executed tools.
+
+## Requester entrypoints
+
+The requester must use the exact `source_session_v1` profile on the same
+coordination runtime as the intended local Chat host. Legacy requester profiles,
+group conversations and other executors are unavailable in this slice. They are
+not silently migrated or represented as synthetic Goals.
+
+The existing manager inbox entry exposes the local Chat host:
+
+```sh
+loopx manager-inbox --goal-id source-goal --agent-id requester \
+  original-conversation --conversation-operation discover \
+  --conversation-file discover.json --chat-url http://127.0.0.1:8767
+```
+
+`discover.json` contains `{"parent_request_id":"<exact parent request id>"}`.
+Use the returned `recipient` object unchanged. A request file contains
+`parent_request_id`, `recipient`, a stable `operation_id` and the existing
+`collaboration_brief_v0` object. The brief names purpose, context, constraints,
+relative input references (and available digests), observable acceptance and
+return requirements. `--conversation-operation request` publishes it.
+The CLI supplies requester identity and runtime location; caller-authored
+requester or runtime fields are rejected.
+
+The existing collaboration MCP server exposes
+`original_conversation_collaboration(operation, parameters, chat_url)` for the
+same discover, request and control operations. The HTTP transport accepts only
+an intended local loopback service, checks its exact runtime and does not follow
+redirects or proxies. This is a trusted local boundary, not remote authentication.
+
+## Execution, correction and recovery
+
+The versioned `collaboration_original_conversation_recipient_v0` address binds
+the original binding and Session to a digest of its verified provider, operator,
+audience, project, executor and native-thread identity. Session IDs and workspace
+paths alone grant no authority. Multiple live Sessions claiming the same native
+thread make the recipient unavailable.
+
+Publication persists the immutable operation, exact original return route and
+shared request record before admitting a peer Turn to the original FIFO.
+Same-operation retries recover the same request and its current revision's Turn. Changed recipient,
+source or content under that identity rejects; use the existing revision control
+for a correction. Grant, source lineage, cancellation, recipient identity and
+revision are rechecked before native model input and before result publication.
+Receiving context never expands the receiver's workspace or tool permissions.
+
+The receiver reads the current brief and independently returns
+`adopt`, `defer`, `reject` or `no_change`, a reason and an evidence-backed
+conclusion. The per-Turn response schema also binds the answer to the supplied
+request revision and digest. Resuming an existing native thread requires neither
+new dynamic tools nor Goal execution mode.
+
+For `--conversation-operation control`, the file contains `recipient`,
+`request_id`, `control` (`inspect`, `revise` or `cancel`) and
+`parameters`. Inspect returns the current control view. Revision and cancellation
+use the existing stable operation ID and expected revision/digest fields;
+revision supplies the corrected brief and reason. Each accepted revision enters
+the same Session FIFO once, including corrections after an earlier answer was
+read. It has its own revision/digest-bound Turn; superseded Turns cannot start
+new model input or publish a current result. Original revision-one Turn keys remain
+readable. Cancellation uses the existing interrupt owner for only this request's outstanding Turns. A late or
+cancelled answer cannot become a current result. The panel shows the current
+revision's queue/result state and retains earlier conclusions as history.
+
+Publication/enqueue response loss is recovered by retrying the same operation.
+If correction persistence succeeds but queue admission fails, retry that same
+correction operation or original publication to recover the current revision.
+Actual structured model output is saved before result IO, so a lost return write
+can recover that revision's assessment and conclusion without invoking the model again.
+The original failed Turn remains failed; the panel separately reports a recovered
+result. A failure before saved model output remains visible and cannot be
+silently rerun as a new Turn under the same identity.
+
+Read the result through the requester's existing manager inbox and use
+`acknowledge-return` / MCP `consume_peer_result` to record consumption after
+checking it. The saved requester route is verified at dispatch, source control,
+requester read and consumption. Results do not automatically go to the
+recipient conversation's external audience.
+
+## Qualification boundary
+
+Isolated File/SQLite integration uses the real source, binding, request, FIFO,
+HTTP, revision, result and requester readback owners. The model transport and
+provider identity observations are synthetic. Compatibility checks preserve
+ordinary human input and registered recipients. Packaged desktop/narrow browser
+inspection covers discovery, explicit grants, mixed queue/result states, long
+content, unavailable readback and revocation.
+[Packaged views and their observed boundary](media/original-project-collaboration/README.md)
+retain the desktop and narrow evidence.
+
+These checks qualify the proposed local path. They do not establish installed
+provider delivery, real model quality, natural receiver adoption, requester
+benefit or long-horizon cost improvement. Those remain separate acceptance
+before a release or completion claim.
