+succeeds with the same native session. A second explicit fixture turn proves
+actual native `session/load` and reaches `end_turn`. The fixture uses exactly two
+loopback responses, a synthetic credential and test-only model metadata;
+it makes no paid calls and does not qualify authenticated model selection. This
+supports the stale durable runtime-context diagnosis; the failed Product run did
+not retain the underlying wire error. Cold rotated restoration now takes the
+current authenticated runtime context. Live reconnect and pending warm-transition
+receipts keep their existing context; replacing that context in an active provider

+### Native instruction delivery
+
+The current candidate is profile v4. Its declaration binds native personal-file
+instruction delivery, including replacement under the provider lifetime lease before native launch. The isolated
+`COPILOT_HOME/copilot-instructions.md` is written atomically with mode 0600 under
+the protected provider home, and empty instructions replace any stale content.
+Concurrent contenders rejected by the lease and unauthenticated admissions do
+not mutate the instruction file. The host awaits each write before releasing its
+lease, including cancellation, so a late write cannot overwrite a successor.
+Profile v3 identities are rejected before native launch; historical evidence
+below remains labeled with its original profile and source.
+
+The [native model-request probe](../../packages/paperclip-runner/test/fixtures/copilot-native-instruction-delivery-2026-09-29.json)
+retains a separate instruction-delivery failure: Copilot 1.0.88 ignores generic
+ACP `_meta.systemPrompt` on new sessions, and ACPX does not include it on load.
+Actual loopback model requests contained neither the Paperclip prompt nor the
+registered directory guidance. Passing a refreshed descriptor alone is insufficient.
+
+A credential-free follow-up wrote the composed text to the isolated provider
+home's `copilot-instructions.md`, using Copilot's native personal-instruction
+mechanism. The first request's system message contained the old directory and
+original entry. After closing the provider, deleting the old directory and
+reopening with fresh instructions, actual `session/load` and a second explicit
+turn completed. The second model request contained the current directory and
+updated entry, with neither old value in its system message. Both attempts used
+two synthetic loopback responses and no paid calls. This probe is not a final
+built-production or authenticated qualification result. A follow-up
+[source-level v4 probe](../../packages/paperclip-runner/test/fixtures/copilot-v4-native-instruction-delivery-2026-09-29.json)
+uses the actual production sandbox writer and confirms the same new/load model
+request behavior. The [post-lease source probe](../../packages/paperclip-runner/test/fixtures/copilot-v4-owned-instruction-delivery-2026-09-29.json)
+reconfirms this after moving refresh under lifetime ownership, and retains an
+earlier zero-call lease-admission failure. The final frozen pack still requires

+internal-team-gated interactive CLI feature and is not used by this integration.
+Those facts invalidate any assumption that prior transport success alone proved

+
+The owned `paperclip-cursor-instructions-v2` patch preserves the v3 isolation and
+typed-error changes and adds the composed instructions through Cursor's native
+`LocalResourceProvider.additionalRules` path. The sandbox supplies an ephemeral,
+controller-owned `PAPERCLIP_CURSOR_INSTRUCTIONS` payload. Ambient environment
+cannot select or replace it, and it is not persisted in ACPX's launch environment
+record. The payload binds exact UTF-8 content (maximum 32 KiB, no NUL) to SHA-256;
+it includes the already-composed governance, custom entry content and registered
+agent-home context, without discovering another workspace instruction file.
+Explicit empty content has an empty rules list and the SHA-256 of empty bytes.
+
+Native session creation and load both use this process-owned snapshot and return
+`_meta.paperclipCursorInstructions` with schema, exact digest, and byte length.
+The additional rule uses the native global-rule representation and retains
+native ordering: additional rules precede the ordinarily discovered project
+rules in `RequestContext.rules`. It is not prepended to the user's message and
+does not replace Cursor's built-in system prompt. The synthetic rule identifier
+is `paperclip://runtime/instructions`; no generated instruction file is exposed
+to workspace discovery.
+
+A synchronous ACPX `protocolGuardFactory` checks each connection independently.
+It correlates the acknowledgement with the exact new/load request and session,
+rejects missing or mismatched acknowledgements before SDK dispatch, and blocks

+## Diagnose failures before buying another campaign
+
+Use this loop to turn eval failures into product improvements. The unit of work
+is a broken user outcome or invariant, not an individual red cell.
+
+1. **Freeze the evidence.** Record the inspected application revision and each
+   campaign's evaluated revision, definition/grader fingerprint, model/profile,
+   environment, exact selected IDs, attempts, and usage coverage. Read the
+   history feed and retained attempt records before launching models. A report
+   refresh, skipped workflow, passing unit suite, or old-definition green cell
+   is not a new live measurement. Inventory explicit-only suites separately
+   from `--all`.
+2. **Reconstruct the failed boundary.** Read durable task state, interactions,
+   event chronology, source/worker identity, delivered output, and the failing
+   assertion. State whether the test reached the boundary it claims to test.
+   Separate observed failure, machine class, analytical cause, and confidence.
+   A cancelled queued wake does not by itself prove lost work; a failed decline
+   assertion does not prove unauthorized execution. A saved artifact does not
+   prove the user received a correct completion update.
+3. **Group by cause and product contract.** Join cells only when their evidence
+   supports the same mechanism. Check for already-merged fixes and definition
+   corrections before proposing new work. Keep product defects, provider/model
+   behavior, grading defects, infrastructure, and unexercised boundaries
+   distinct. Preserve the original grades when attribution changes.
+4. **Design the smallest general correction.** Name the desired user behavior,
+   the authoritative state/transaction or provider boundary that owns it, the
+   affected callers, and the existing guarantees that must survive. Check it
+   against `PRODUCT.md` and `SPEC-implementation.md`. A change to an intentional
+   product rule is a contract change, not an excuse to delete its guard. Avoid
+   case-name branches, phrase-specific prompts, unconditional retries, or
+   weakening approval, ownership, cancellation, and budget gates to get green.
+5. **Prove the mechanism cheaply.** Calibrate a grader against correct and
+   plausible wrong retained evidence. Reproduce a product race with scripted
+   providers or service tests. Pair every proposed fix with a regression that
+   exercises the opposite boundary (for example, eligible delivery versus
+   revoked access, benign obsolete wake versus interrupted active work).
+   Presentation-only changes use the existing report refresh path and make no
+   provider calls; do not claim replay can prove changed runtime behavior.
+6. **Select a bounded live confirmation.** Write the exact failed representative
+   IDs and only the passing controls affected by the change. Pin the source,
+   definitions, models, and remote image. Record an attempt cap, provider and
+   compute budget, wall-clock deadline, and concurrency before dispatch under
+   the existing live-run authorization. Missing pricing means unknown, not free.
+   Do not rerun unaffected green cells during diagnosis or retry usable behavior
+   failures until they happen to pass. Preserve every attempt. Expand to a
+   compatible qualification campaign only after the causal fix passes.
+7. **Close with evidence and remaining scope.** Report original versus new
+   measurements, exact selected coverage, regression results, cost coverage,
+   and unresolved boundaries. A partial verification may close one defect; it
+   cannot turn the full catalog green or establish reliability from one attempt.
+
+Keep one triage record per cause with: affected cell IDs; evidence links;
+observed failure; supported cause and confidence; existing fix/revision; proposed
+product contract; invariant regressions; next exact live selection; budget and
+stop condition; owner; and disposition. Useful dispositions include confirmed
+product defect, model behavior, grader correction, infrastructure repair,
+fixed-but-not-remeasured, historical pass, and unqualified coverage.
+
+Parallelize independent artifact inventory, deterministic checks, and isolated
+cells. Keep a cell's dependent turns ordered. When delegating, use inexpensive
+agents for bounded extraction, catalog reconciliation, and test execution; keep
+causal attribution, product design, and final review with the lead. Begin local
+browser campaigns at the documented conservative concurrency and increase only
+with measured host headroom. Hosted fanout must respect the workflow's provider
+and fleet caps; more simultaneous timeouts do not improve wall-clock efficiency.
+
+Current tools support exact-ID selection and retained-evidence report refresh,
+but not an automatic cause-aware "rerun unresolved failures" planner. Build an
+explicit selection manifest rather than treating `--all` as that planner. Review
+the launcher's automatic retry policy when budgeting; Product E2E may create one

+# Return completed work to its originating chat
+
+## Summary
+
+When an agent hands off work from Agent Chat, Paperclip will bring the finished result back to that conversation automatically. The original agent will write the update using the task’s recorded status and saved output.
+
+Report tasks as they finish. Combine completions already waiting for the same reply. A `/new` reset suppresses updates from the previous conversation session.
+
+The merged completion-update evals are the baseline. This change should turn the missing-update cases green and address the stale onboarding replies.
+
+This behavior applies to Agent Chat handoffs and the onboarding completion-update fix below, not all agent handoffs in general. It uses the existing Agent Chat availability setting and adds no separate experimental flag.
+
+## Implementation
+
+**Record the handoff automatically.**
+
+- Add a durable, company-scoped handoff record linking the created task to the source conversation, its session generation, and its agent.
+- Capture it inside task creation using the authenticated creating run. Both native `create_task` and HTTP task creation already supply that context. Do not rely on the model to provide a source ID.
+- Keep execution tasks as ordinary project tasks. Do not turn the conversation into their parent or block it on their completion.
+- Preserve existing creation idempotency: replaying task creation must not create another handoff.
+
+**Queue completion durably.**
+
+- Create a completion-delivery record in the same transaction that moves a linked task into Done. Cover both ordinary issue updates and native status-decision commits.
+- Identify each event by the handoff and committed completion transition. Repeating the same transition must not create duplicate deliveries.
+- Use a small database-backed outbox, following the existing delivery-service pattern. Process it immediately after commit and through startup and periodic recovery.
+- Reopening a task before delivery supersedes its pending completion. Completing it again creates a new event.
+- Start with newly created handoffs. Do not backfill historical tasks or emit old completion notices.
+
+**Run an agent-authored follow-up.**
+
+- Add a dedicated completion wake reason in `server/src/services/agent-conversations.ts` and `server/src/services/heartbeat.ts`.
+- Wake an idle conversation. If a reply is underway, queue a subsequent turn; never treat an update to the running turn’s stored context as delivery.
+- At turn start, collect pending completions for that conversation session. Completions arriving after that point wait for another turn.
+- Supply current task status, task links, saved deliverable references, and bounded result content. Keep task output separate from trusted instructions.
+- Tell the agent to explain what finished and provide access to the result. Do not prescribe canned wording or authorize additional execution.
+- Use the existing conversation response path. Record delivery against the persisted agent reply, not merely an enqueued or successful run.
+
+**Handle recovery and onboarding.**
+
+- Carry delivery IDs through wakeups, retries, and response persistence. Before retrying, check for an already-published reply; make publication and delivery acknowledgement atomic.
+- Use leased claims and bounded retries following existing delivery conventions. Retain exhausted failures for diagnosis.
+- Check the conversation’s session generation before scheduling and publishing. Suppress old-session deliveries after `/new`.
+- Add `issue_children_completed` to the existing follow-up scheduling rule so onboarding completion cannot disappear into an active parent run. Refresh completion facts when that follow-up starts. Apply this scheduling change to onboarding flows; preserve existing scheduling for other handoffs.
+- Preserve company access, agent permissions, budgets, and pause controls. Result delivery must not broaden general access to other tasks.
+
+No new user-facing tool, notification settings, onboarding option, or UI component is required. Add the database migration and synchronized internal types; preserve existing public task-creation inputs.
+
+## Tests and evals
+
+**Deterministic service and integration tests**
+
+Cover both task-creation paths and both completion paths, including:
+
+- Idle versus actively replying conversations.
+- Multiple pending completions combined without losing task identities.
+- Duplicate events, concurrent dispatchers, and restart recovery.
+- Crashes before dispatch and after reply persistence.
+- `/new`, task reopening, cross-company inputs, and paused agents.
+- Onboarding child completion during an active parent turn.
+- Existing Agent Chat availability controls and unaffected behavior for other agent handoffs.
+
+**Product E2E evals**
+
+Extend the explicit `completion-updates` suite for native Claude and Codex:
+
+- Retain the existing onboarding and idle-handoff stories.
+- Add completion during an active chat reply, multiple-task completion, and interrupted completion-reply recovery.
+- Establish each timing boundary with observable run state and bounded fixture gates. Use real browser/API actions; do not inject completion messages or edit database state.
+- Require durable Done status, saved output, an unsolicited source reply, working result access, and no duplicate completion update.
+
+Add a separate completion-accuracy grader using the existing pinned judge infrastructure. It must cite recorded evidence and reject stale promises such as “the work will run next” after completion. Calibrate it against accurate replies, stale replies, unsupported claims, and later corrections. Missing judge evidence leaves accuracy unqualified; it cannot override a mechanical failure.
+
+Run the selected cells in GitHub Actions. Preserve source revisions, grader versions, attempts, timing, cleanup, and cost coverage. Require two consecutive complete campaigns to pass delivery, access, and accuracy before calling this scope qualified.
+
+## Rollout and defaults
+
+- Enable completion follow-ups wherever Agent Chat is already enabled; leave native-runner onboarding selection unchanged.
+- Report Done transitions only. Progress, blocked, failed, and cancelled notifications remain outside this change.
+- Report each task as it finishes, combining already-pending completions without an artificial batching delay.
+- Suppress old-session updates after `/new`; keep tasks and results intact.
+- Record pending, delivered, superseded, and exhausted events in instance-local diagnostics.
+- Submit a separate product PR with unit/integration coverage, live eval reports, and passing merge checks. The previously merged eval baseline remains the red reference.
+
+## Implementation security refinement
+
+Completion input carries server-recorded task identifiers, Done status, timestamps,
+and result links. Worker-authored titles, document bodies, and comments are not
+copied into the source agent's prompt; the result remains on the linked task.
+Tool authority and provider permissions retain their normal configured defaults.
+The original agent writes the completion reply from these facts and its existing
+conversation context. Evals independently read the saved output and grade the
+reply's truthfulness and result access.

+closed allowlist of public process settings, known boolean flags, and run identifiers,
+connection URL passwords, the run API key, and common credential forms before
+truncation. It removes control characters,
+retains line breaks for JSON and stack traces, and preserves up to 4,096 title
+characters and 24,576 detail characters. These bounds also keep the escaped
+transcript JSON below the server's 64 KiB chunk limit. Longer fields end with an explicit
+omission count and appear in `truncatedFields`. The error message includes the
+same sanitized text. Ordinary run retrieval preserves the bounded structured
+diagnostic even when multibyte text or other result fields exceed the result
+byte budget. In that reduced response, title and details have 1 KiB and 8 KiB
+byte budgets, including truncation markers. `retrievalTruncated` directs callers
+to the full adapter-bounded text in the run error or transcript. Other provider
+metadata and action payloads are not copied.
+
+Recovery still uses the typed failure category and the adapter's existing
+classifier. Provider warnings do not become failures, and timeouts or lost
+control channels keep their authoritative failure messages. These diagnostics
+stay in the instance's run records and configured run-log storage. They add no
+Paperclip Telemetry or OpenTelemetry export.
