+# Implementation Plan: Workflow entry saved-prompt delivery
+
+## Overview
+
+Preserve saved-prompt definitions when workflow entry starts or resets a session.
+One sequential work order carries trusted context through composition, recording,
+and launch. It then verifies the profile-switch round trip and recovery paths.
+
+Issue: [#3922](https://github.com/kdlbs/kandev/issues/3922).
+The task system owns prompt delivery. Existing criteria cover persistence,
+trust, lookup failure, and passthrough behavior. Added criteria 001.12 and
+001.13 make workflow-entry and recovery outcomes explicit.
+
+## Evidence and root cause
+
+Source inspected at `3aa3233c78`:
+
+1. `task_operations.go:buildWorkflowEntryPrompt` calls `buildWorkflowPrompt`,
+   which discards the trusted-context return from `buildWorkflowPromptWithContext`.
+2. `event_handlers_workflow.go:autoStartStepPrompt` injects runtime context for
+   CREATED sessions and context resets. Its trusted arguments omit saved-prompt context.
+   Canonicalization therefore removes the generated expansion before recording.
+3. `task_operations.go:startCreatedSessionWithComposedPrompt` passes an empty
+   context to `startCreatedSession`. That method skips composition but still
+   calls `wrapCreatedSessionPrompt`, creating another removal boundary.
+4. Running-session dispatch usually bypasses these injectors. This explains
+   why the same workflow prompt works without a session switch.
+
+A temporary `TestReproIssue3922` used the real SQLite prompt service and
+`buildWorkflowEntryPrompt` with `Follow @demo-rule`. The expansion existed before
+canonicalization and disappeared afterward. A control passed the resolver's exact
+trusted value and retained the saved definition once. The diagnostic passed:
+
+```bash
+(cd apps/backend && go test ./internal/orchestrator -run '^TestReproIssue3922$' -count=1 -v)
+```
+
+This proves the composition/canonicalization defect, not the complete profile
+routing flow or a working fix. The temporary file was removed. Permanent
+integration regressions remain part of implementation.
+
+## Scope
+
+### In scope
+
+- Preserve generated context on explicit auto-start and implicit profile-switch launches.
+- Cover P1 to P2 and P2 to P1, existing-session controls, and context resets.
+- Preserve context through composed launches and missing-execution recovery.
+- Compare persisted and dispatched expansions, including Office context injection.
+- Preserve existing handoff, entity-reference, mode, and queue behavior.
+- Gate shared saved-prompt mutations on `org.config.manage` while preserving
+  member reads and reference use.
+- Update the workflow saved-prompt public guidance with the implemented guarantee.
+
+### Out of scope
+
+- Literal system-tag truncation or prompt-editor validation from the issue's secondary report.
+- New UI warnings, fail-closed resolution, or prompt matching rules.
+- Profile routing changes, queue schema changes, and queued-message edit/merge semantics.
+- Passthrough expansion, frontend changes, release flags, or database migrations.
+
+## Technical approach
+
+Change `buildWorkflowEntryPrompt` to return prompt, trusted expansion context,
+and error. Use `buildWorkflowPromptWithContext` after the existing fallback claim.
+Update every production caller and affected test caller.
+
+Carry the context explicitly through `autoStartStepPrompt`, both runtime-context
+injectors, and `startCreatedSessionWithComposedPrompt`. Pass it into the existing
+`startCreatedSession` context argument. Do not recover trust from tagged text.
+Use a small private input/options structure if needed to avoid excessive positional arguments.
+
+Audit `StartSessionForWorkflowStep`, `promptTaskOptions`, and
+`fallbackFreshLaunchOnMissingExecution`. Preserve the matching context across
+already-composed retries and final launch wrapping. Replacement branches that
+rebuild the prompt must use their newly returned context.
+
+Keep queued replay on its existing backend-authoritative preparation path.
+Add a queue/recovery regression to detect stripping or duplicate expansions.
+Do not add persisted trust metadata or expand queue semantics for this repair.
+Keep mode transforms single-pass and completion handoff text last.
+
+The existing [server-owned expansion ADR](../../decisions/2026-09-01-server-owned-saved-prompt-expansion.md)
+remains authoritative. No new authority boundary or ADR is needed.
+The completed Quick Chat and launch-fallback packages retain their completed scope
+and recorded results; this package owns the additional workflow regressions.
+
+## Tests
+
+New tests belong in
+`apps/backend/internal/orchestrator/workflow_entry_saved_prompt_test.go`.
+Use the real prompt service fixture from `prompt_launch_fallback_test.go`.
+Do not append new cases to oversized existing test files.
+
+All criterion suffixes below refer to `AC-TASKS-SAVED-PROMPT-DELIVERY-001`.
+
+| Criteria | Planned regression |
+| --- | --- |
+| .6, .12 | `TestWorkflowEntrySavedPrompt_ProfileSwitchRoundTrip`: drive P1/P2/P1 through `processOnEnter` with no `auto_start_agent`; capture stored messages and asynchronous implicit-launch requests. |
+| .6, .12 | `TestWorkflowEntrySavedPrompt_DispatchModes`: CREATED, reused WAITING_FOR_INPUT, ordinary reset, and Office reset-context sessions; plan mode. The Office case asserts the Office tool context and saved expansion in both prompt boundaries. |
+| .6, .12, .13 | `TestProcessOnEnterImplicitProfileSwitchTerminalizedGuard`: terminalize the reused profile session at the deterministic pre-dispatch barrier, then verify the production replacement launch's session identity, stored and dispatched saved definition, and completion handoff. `TestAutoStartStepPrompt_ReplacementLaunchReusesClaimedHandoff` remains a same-session shared-claim control. |
+| .6, .13 | `TestWorkflowEntrySavedPrompt_Recovery` and `TestStartSessionForWorkflowStep_ComposedHandoffSurvivesLazyResumeFallback`: missing execution and composed workflow-step recovery. |
+| .4, .5, .8 | `TestWorkflowEntrySavedPrompt_TrustGuards`: forged blocks, unknown references, lookup failure, absent expander, passthrough, and empty prompt. |
+| .12, .13 | `TestWorkflowEntrySavedPrompt_Composition`: nested references and workflow-level references. `TestWorkflowEntrySavedPrompt_DispatchModes` covers plan mode; the recovery test covers completion handoff ordering. |
+| .13 | `TestSendQueuedNowConsumesCeilingLaunchAndPreservesWorkflowPrompt`: queued Send Now preserves the accepted expansion in the deferred launch. `TestExecuteQueuedWorkflowPrompt_MissingExecutionKeepsDrainExpansion`: a workflow queue message is re-resolved before it is recorded; if the saved definition changes during failed dispatch, the fresh-runtime launch keeps the drain-time expansion. |
+| .14 | `TestPromptMutationsRequireOrgConfigManage` denies member POST, PATCH, and DELETE; `TestPromptReadsRemainAvailableToOrgMembers` preserves shared prompt reads. |
+
+Run the CREATED-session regression before production edits. It must fail because
+the saved definition disappears, not because the fixture fails to launch.
+Assert visible references remain and each canonical prompt contains exactly one
+expansion block. Compare the saved definitions in persistence and dispatch.
+For prepared retries, mutate the saved record between preparation and wrapping
+and assert that the carried definition is not silently replaced.
+
+## End-to-end evidence
+
+Backend service integration tests exercise routing, composition, message storage,
+and the agent-manager dispatch boundary. Mock external agent execution only.
+Use existing profile-switch and handoff fixtures with deterministic synchronization.
+No browser control or rendered UI changes, so no new Playwright test or UI preview is required.

+## Work orders

+
+## Verification results
+
+Diagnostic reproduction passed on 2026-09-25 and was removed. The implementation
+and its verification completed on 2026-09-25:
+
+- The focused orchestrator race suite passed, including workflow-entry
+  dispatch, profile routing, composed launch, and fresh-runtime recovery tests.
+- Review follow-up race tests passed for the Office reset injector, the
+  no-`auto_start_agent` P1/P2/P1 asynchronous launches, and terminalized-session
+  replacement with the carried handoff.
+- The prompt service and system-prompt race tests passed.
+- Additional recovery, ceiling-deferral, and queued Send Now preservation tests
+  passed under the race detector.
+- `go build ./...` passed from `apps/backend`.
+- `python3 scripts/list-docs.py validate` validated 305 decisions and 1151
+  specifications; `python3 scripts/lint-spec-files.py --all` passed.
+- The public-doc validator tests passed (62 tests), and the validator accepted
+  all 47 published pages.
+- `gofmt` and `git diff --check` passed.
+- PR fixup coverage passes for prompt mutation authorization, member reads,
+  non-composed recovery, queued workflow recovery after an in-flight saved-prompt
+  edit, and a nil workflow step. The queue resolves once at drain before the
+  message row is recorded, then fresh-runtime recovery carries that trusted
+  context.
+- Shared prompt mutations now require `org.config.manage`. Public documentation
+  states that prompts are instance-shared and records the current multi-org
+  admin boundary.
+
+The public workflow guidance now documents the preserved-context behavior. The
+issue remains assigned to `carlosflorencio`. The implementation and its PR
+fixup are tracked in [PR #3931](https://github.com/kdlbs/kandev/pull/3931).
+
+## Risks
+
+- Fixing only the first injector still loses the expansion at the second injector.
+- Re-reading mutable definitions after recording can make persistence differ from dispatch.
+- Trust inferred from prompt text would bypass the existing security boundary.
+- Signature changes touch retry and replacement paths with cancellation and admission guards.
+- Broad recomposition can duplicate plan-mode context, references, or handoff text.

+# Task 01: Preserve workflow expansion context
+
+## Summary
+
+Carry backend-generated saved-prompt context through workflow dispatch and composed
+session launch. Prove that profile switches and recovery preserve the same
+saved definitions in message storage and agent input.
+
+## In scope
+
+- Implement the explicit context flow described in the plan and system design.
+- Cover every `buildWorkflowEntryPrompt` caller and downstream canonicalizer.
+- Add all five regression groups named in the plan with the real prompt service.
+- Re-resolve queued workflow auto-start references at drain before message
+  recording, then preserve that exact context through missing-execution recovery.
+- Require `org.config.manage` for shared prompt mutations while retaining member
+  reads and reference use.
+- Update public saved-prompt and authentication guidance after the fix passes.
+
+## Out of scope
+
+Literal-tag editor validation, new warnings, frontend changes, profile routing,
+queue schemas, and passthrough expansion.
+
+## Acceptance
+
+1. P1/P2/P1 moves through the no-`auto_start_agent` implicit path and context resets retain one backend-generated expansion with matching stored and dispatched definitions.
+2. A reused profile session that terminalizes before async dispatch is replaced through the production path; the replacement prompt preserves its session identity, one saved expansion in storage and launch, and the carried handoff. Missing-execution paths retain context without duplicate handoffs, mode wrappers, or messages; queued retry remains functional.
+3. Forged blocks remain untrusted, lookup failure remains non-fatal, and passthrough sessions receive no hidden expansion.
+4. Org members cannot create, update, or delete shared saved prompts without `org.config.manage`; they can still list and use them.
+
+## Implementation sequence
+
+1. [x] Read the linked design, plan, source, and backend test guidance.
+2. [x] Mark this work order `in_progress`.
+3. [x] Add `TestWorkflowEntrySavedPrompt_DispatchModes` and observe the CREATED case fail from missing saved content.
+4. [x] Return trusted context from workflow entry and propagate it through both injection stages.
+5. [x] Complete the round-trip, recovery, composition, and guard test groups.
+6. [x] Run the exact checks below and record their results.
+7. [x] Mark this work order `done` and synchronize the plan.

+
+## Results
+
+Implemented explicit saved-prompt context propagation through workflow composition,
+session launch, profile replacement, dispatch recovery, and admission replay.
+Added regression coverage for CREATED and reused sessions, context resets, Office
+injection, P1/P2/P1 profile switches, composition and trust guards, mutable-prompt
+recovery, ceiling deferral, and queued Send Now. Public workflow guidance now
+documents the guarantee.
+
+Review follow-up coverage now proves that `DispatchModes` reaches the Office
+reset injector; `ProfileSwitchRoundTrip` covers asynchronous P1/P2/P1 dispatches
+without `auto_start_agent`; and `TestProcessOnEnterImplicitProfileSwitchTerminalizedGuard`
+terminalizes a reused session at a deterministic barrier before dispatch. The
+production replacement launch is checked for replacement session identity, one
+matching saved-definition block in the stored and launched prompt, and one carried
+completion handoff. `TestAutoStartStepPrompt_ReplacementLaunchReusesClaimedHandoff`
+remains a same-session shared-claim control.
+
+The original work-order verification passed on 2026-09-25: the orchestrator
+race suite, prompt-service/system-prompt race tests, changed-signature and
+queued Send Now regressions, `go build ./...`, catalog validation, specification
+lint, public-doc tests (62 passed), public-doc validation (47 pages), gofmt, and
+`git diff --check`. The review follow-up focused orchestrator race command also
+passed.
+
+The PR fixup adds `TestExecuteQueuedWorkflowPrompt_MissingExecutionKeepsDrainExpansion`,
+which drives `executeQueuedMessage`, records the drain-time definition, changes
+the saved prompt during the failed provider dispatch, and verifies the
+fresh-runtime replacement uses the same one-block context.
+`TestWorkflowEntrySavedPrompt_UncomposedRecoveryCarriesTrustedContext` covers
+the non-composed recovery branch with a saved-prompt edit.
+`TestPromptMutationsRequireOrgConfigManage` denies member POST, PATCH, and
+DELETE; the read regression keeps list access open.
+`TestInjectAutoStartRuntimeContext_NilStepPreservesPrompt` covers the defensive
+nil case.
+
+The targeted fixup command passed on 2026-09-25:
+
+```bash
+(cd apps/backend && go test ./internal/prompts/handlers ./internal/orchestrator -run '^(TestPromptMutationsRequireOrgConfigManage|TestPromptReadsRemainAvailableToOrgMembers|TestWorkflowEntrySavedPrompt_UncomposedRecoveryCarriesTrustedContext|TestExecuteQueuedWorkflowPrompt_MissingExecutionKeepsDrainExpansion|TestInjectAutoStartRuntimeContext_NilStepPreservesPrompt)$' -count=1)
+```
+
+Post-fixup validation also passed:
+
+```bash
+(cd apps/backend && go test -race ./internal/orchestrator -run '^(TestWorkflowEntrySavedPrompt_(DispatchModes|ProfileSwitchRoundTrip|Recovery|UncomposedRecoveryCarriesTrustedContext)|TestProcessOnEnterImplicitProfileSwitch.*|TestAutoStartStepPrompt_ReplacementLaunchReusesClaimedHandoff|TestExecuteQueuedWorkflowPrompt_MissingExecutionKeepsDrainExpansion|TestInjectAutoStartRuntimeContext_NilStepPreservesPrompt)$' -count=1)

+```
+
+The public-doc tests passed (62 tests), and the validator accepted all 47
+published pages. The follow-up also passed `gofmt` and `git diff --check`.

An org admin can therefore affect install-wide behavior, including prompt instructions used by other organizations, and can download backups that contain their data.
 - **WebSocket notification routing is not a strict access boundary.** Workspace-aware fan-out normally narrows recipients by reach, but the regular path falls back to global delivery if reach and owner resolution both fail. See [WebSocket API](websocket-api.md#emitted-notifications-and-recipients).
 - **Filesystem and agent credentials are not isolated.** Worktrees and repositories live under one `~/.kandev` tree owned by the OS user running the backend, and agent CLI logins (`gh auth`, `claude login`, provider API keys) authenticate as that OS user, so all app-users share the same on-disk agent credentials, and anyone with shell access to the server can read all files. Authentication isolates users' kandev *data* at the application layer, not the filesystem or per-user agent auth. For hard isolation of agent credentials, run a separate kandev instance per user (or use OS-level access control / sandboxed executors).
 - Local accounts only for now; the account model is ready for OIDC/SSO later.
