The workflow plugin's send middleware intercepts these replies at ROUTING priority and returns { action: 'deny' } to block delivery. Changes: - Added defensive check in workflow send hook to split the ownsBot condition - Added warning when send middleware is not available - Added regression test verifying ephemeral replies are denied - Added test verifying persistent Bot replies are not affected Ran: cd /workspace/core && npm test cd /workspace/plugins/workflow && npm test node scripts/ds-bot-patches.mjs generate && check All tests pass.

The workflow plugin's send middleware intercepts these replies at ROUTING priority and returns { action: 'deny' } to block delivery. Changes: - Added defensive check in workflow send hook to split the ownsBot condition - Added warning when send middleware is not available - Added regression test verifying ephemeral replies are denied - Added test verifying persistent Bot replies are not affected Ran: cd /workspace/core && npm test cd /workspace/plugins/workflow && npm test node scripts/ds-bot-patches.mjs generate && check All tests pass. Patches regenerated and verified in sync. Docs-not-needed: Internal defensive improvement to workflow send hook; no architecture changes, no new APIs, no behavior changes to workflow subsystem that require documentation updates.

After stepResult→releaseRun, ownsBot() returns false (bot no longer in run.ephemeral) 2. Second/deferred replies bypass gated() check (deferred/resumed flags set) 3. These paths call innerDeliver directly, queueing [Reply from ...] messages Real fix: Check durable bot.ephemeral flag in wrapped rt.deliver BEFORE gated() check. Deny ALL bot-to-bot deliveries (reply, stopped, report) from bots marked ephemeral, regardless of: - Gating state (gated vs non-gated paths) - Delivery flags (deferred, resumed, retried, resent) - Workflow ownership (owned vs post-release) The workflow send hook still runs for gated deliveries and calls stepResult; the new check catches bypass scenarios where middleware never ran.

Bug 2 - post-removal still leaked: After bot.remove, rt.botOf() returned undefined, so ephemeral check failed and innerDeliver still ran. Real fix: 1. EXPAND gated() check: ephemeral bot deliveries (or tombstoned ids) ALWAYS return true, EVEN with deferred/resumed/retried flags. This routes them through run()/middleware where workflow-step hook calls stepResult. 2. TOMBSTONE on remove: workflow plugin calls rt.tombstoneEphemeral(id) before bot.remove. Late replies from tombstoned ids are denied even though bot no longer exists. 3. Post-removal check: if tombstoned AND bot is gone, deny before middleware. 4. Workflow send hook unchanged: still calls stepResult then returns deny. This ensures: - First reply: middleware runs → stepResult advances → deny blocks delivery - Deferred/resumed/retried reply: gated by ephemeral flag → middleware runs - Post-removal reply: tombstone check denies (bot gone, no middleware needed) - Request TO ephemeral: allowed (sender is not ephemeral) Changes: - core/src/host/hooks.js: Expand gated(), add tombstone Set + rt.tombstoneEphemeral - plugins/workflow/index.js: Call rt.tombstoneEphemeral before bot.remove - core/test/workflow-reply-leak.test.js: Verify all scenarios including stepResult TZ=UTC npm run verify: green Docs-not-needed: Delivery gate logic; no subsystem architecture change Co-authored-by: Danyang Chen --- changelog.d/1524-workflow-reply-leak.fixed.md | 2 +- core/src/host/hooks.js | 36 +++++--- core/test/workflow-reply-leak.test.js | 92 +++++++++++++------ patches/ds-bot/files/src/host/hooks.js | 36 +++++--- .../files/test/workflow-reply-leak.test.js | 92 +++++++++++++------ plugins/workflow/index.js | 2 + 6 files changed, 177 insertions(+), 83 deletions(-) diff --git a/changelog.d/1524-workflow-reply-leak.fixed.md b/changelog.d/1524-workflow-reply-leak.fixed.md index a02ea82f2..402932674 100644 --- a/changelog.d/1524-workflow-reply-leak.fixed.md +++ b/changelog.d/1524-workflow-reply-leak.fixed.md @@ -1 +1 @@ -**Workflow ephemeral node Bot replies no longer leak into persistent Bot chats.** Previously, ephemeral workflow node Bot replies (e.g., Review / Verify / Rework results) could appear as queued `[Reply from …]` messages in Chief or other persistent Bot conversations, especially when deliveries bypassed the send middleware (deferred, resumed, or after workflow release).

Tombstone via ctx.runtime was dead - plugins cannot access ctx.runtime. Moved tombstoning into removeBot() in hooks.js, called immediately before rt.deleteBot(id) when bot.ephemeral is set. Covers every fb.bot.remove path. Removed ctx.runtime call from workflow plugin. 2. Resent edge - gated() now handles resent from ephemeral/tombstone same as deferred: ephemeral bots always route through middleware even when resent. Normal bots still skip middleware when resent. 3. Ready for rebase onto origin/main after this commit.

Added workflow-reply-leak-real.test.js with focused unit tests proving: 1. Ephemeral with deferred/resumed/retried/resent MUST be gated - RED on origin/main: bypasses gating → leaks to Chief - GREEN with fix: ephemeral forces gated()=true → routes through middleware 2. Post-removal tombstone prevents late deliver - RED on origin/main: bot gone, no tombstone → bypasses gating → leaks - GREEN with fix: tombstone exists → gated()=true → denied 3. Normal (non-ephemeral) bot behavior unchanged - First reply still gated - deferred/resumed/retried/resent still skip gating (as before) - Request TO ephemeral still allowed These test the actual gated() logic from hooks.js directly, showing the before/after behavior difference that fixes the LIVE leak.
