-title: Run-code-Richtlinie
-description: Die Paket-Zulassungsliste und -Sperrliste, die regeln, was sandgeboxtes Run code installieren darf.
----
-
-Run-code-Richtlinie ist die Oberfläche, auf der du entscheidest, welche Python- und Node-Pakete die Sandbox zur Laufzeit installieren kann. Skills mit Skripten und das Run-code-Tool laufen beide in derselben Sandbox; diese Richtlinie ist die einzige Naht, an der du anziehst oder lockerst, was sie installieren dürfen. Admins und Inhaber lesen diese Seite, wenn ein Agent eine neue Bibliothek braucht oder wenn ein Audit fragt, warum ein Paket zu einem bestimmten Zeitpunkt blockiert war.
-
-<Frame caption="Governance > Run-code-Pakete — die Radiogruppe für den Standardmodus über den Zulassungs- und Sperrlisten für Python und Node.">
-
-![Die Governance-Seite Run-code-Richtlinie mit Zulassungsliste als gewähltem Standardmodus, darunter eine Python-Zulassungsliste mit pandas, numpy, scipy und scikit-learn, eine Python-Sperrliste mit paramiko, fabric, pexpect und scapy sowie eine Node-Zulassungsliste mit axios, date-fns, dayjs und lodash.](/images/platform/governance-run-code-policy.webp)
-
-</Frame>
-
-## Ein durchgespielter Wechsel
-
-Der Standardmodus ist **Sperrliste** mit leerer Liste, was bedeutet, dass jedes Paket installierbar ist. Um auf eine kuratierte Menge zu wechseln, öffne **Einstellungen > Richtlinien > Run-code-Pakete**, ändere den Modus auf **Zulassungsliste** und liste die Pakete unter **Python-Zulassungsliste** und **Node-Zulassungsliste** auf, denen du vertraust. Speichern, und der nächste Sandbox-Lauf, der ein Paket außerhalb der Liste anfordert, scheitert mit dem Grund **nicht auf der Zulassungsliste** im Audit-Ereignis.
-
-## Die zwei Modi
-
-| Name            | Default | Beschreibung                                                                                                                                  |
-| --------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
-| Zulassungsliste | aus     | Nur die aufgelisteten Pakete installieren; alles andere wird abgelehnt. Nutz das, wenn ein Regulierer die freigegebenen Bibliotheken benennt. |
-| Sperrliste      | an      | Jedes Paket installiert außer den aufgelisteten. Nutz das, wenn eine kleine Menge als schlecht bekannt ist und der Rest vertraut wird.        |
-
-## Die vier Listen
-
-Jeder Modus liest aus zwei Listen — Python und Node. Ein Paket pro Zeile oder kommagetrennt. Versionsangaben werden automatisch entfernt (`pandas==2.1` entspricht `pandas`), sodass die Richtlinie namensbasiert ist und Bibliotheks-Upgrades übersteht. Scoped Node-Pakete (`@scope/pkg`) werden unterstützt.
-
-Der Modus gilt global: Im Allowlist-Modus lesen beide Sprachen ihre Zulassungslisten, im Denylist-Modus beide ihre Sperrlisten. Die Listen selbst sind pro Sprache — Python und Node halten je ihr eigenes Set.
-
-## Der Tester
-
-Das Test-Panel auf derselben Seite erlaubt dir, pip- oder npm-Spezifikationen einzufügen und zu sehen, ob jede unter dem aktuellen Entwurf durchgehen würde. Es verwendet deine ungespeicherten Änderungen, sodass du vor dem Speichern iterieren kannst. Jede Spezifikation wird geparst, von ihrer Versionsangabe befreit und gegen die Listen abgeglichen; das Panel meldet **Erlaubt** oder **Abgelehnt** mit der Begründung — passt-zur-Zulassungsliste, nicht-auf-der-Zulassungsliste, passt-zur-Sperrliste, nicht-auf-der-Sperrliste.
-
-## Netzwerk-Egress und Skills
-
-Die Paket-Richtlinie regelt, _was_ in der Sandbox läuft. Dieselbe Sandbox läuft Skill-Skripte — siehe die [Skills-Konzeptseite](/de/platform/agents/skills). Ausgehendes Netzwerk aus Sandbox-Code ist standardmäßig offen, Cloud-Metadaten und private Adressbereiche sind immer blockiert; bei selbst gehosteten Deployments kann der Operator es auf Deployment-Ebene auf eine Hostname-Zulassungsliste einschränken — die Anleitung steht in [Hardening](/de/self-hosted/operate/security/hardening). Behandle das Veröffentlichen eines Skills mit Skript als Erweiterung der Vertrauensfläche für jeden Agent, der es aufnimmt; die Paket-Richtlinie und die Egress-Richtlinie des Deployments entscheiden zusammen, was das Skript tun darf.
-
-## Wo das hingehört
-
-Run-code-Richtlinie ist die Schleuse auf der Sandbox, die sowohl das Run-code-Tool als auch Skill-Skripte trägt. Das begleitende Konzept ist [Agent-Skills](/de/platform/agents/skills) — es deckt ab, wann ein Skript als Skill veröffentlicht wird und warum die Paket-Richtlinie die tragende Schleuse ist. Die begleitende Governance-Seite ist [Audit-Logs](/de/platform/admin/governance/audit-logs) — jede abgelehnte Paket-Installation landet dort mit der Spezifikation und der Begründung.

 ## Video-Link-Ingestion (yt-dlp)
 
 Liest Tale einen Video-Link ein, holt es dessen Transkript für den Agenten. YouTube blockiert automatisierten Zugriff von Rechenzentrums-/Server-IPs, sodass dies bei einer Cloud-Bereitstellung fehlschlagen kann. Die Bereitstellung bringt standardmäßig einen PO-Token-Provider verdrahtet mit (das vollständige Bild liefert [Video-Ingestion](/de/self-hosted/configuration/video-ingestion)); die Optionen unten sind optionale Überschreibungen und Eskalationen. Keine garantiert eine Umgehung — eine saubere Ausgangs-IP ist der wirksamste Hebel. Vom Backend-Worker gelesen und bei jeder Ingestion neu ausgewertet, sodass eine Änderung ohne Neustart greift.

-title: Run-code policy
-description: The package allowlist and denylist that gate what sandboxed Run code can install. Admins and Owners read this when an agent needs a new library or when an audit asks why a package was blocked at a given time.
----
-
-Run-code policy is the surface where you decide which Python and Node packages the sandbox can install at execution time. Skills with scripts and the Run code tool both run in the same sandbox; this policy is the single seam where you tighten or loosen what they can install. Admins and Owners read this page when an agent needs a new library, or when an audit asks why a package was blocked at a given time.

-![The Run-code policy governance page with Allowlist picked in the default-mode radiogroup, above a Python allow list holding pandas, numpy, scipy, and scikit-learn, a Python deny list holding paramiko, fabric, pexpect, and scapy, and a Node allow list holding axios, date-fns, dayjs, and lodash.](/images/platform/governance-run-code-policy.webp)
-
-</Frame>
-
-## A worked switch
-
-The default mode is **Denylist** with an empty list, which means every package is installable. To switch to a curated set, open **Settings > Governance > Run-code packages**, change the mode to **Allowlist**, and enumerate the packages you trust under **Python allow list** and **Node allow list**. Save and the next sandbox run that requests a package outside the list fails with the **not on the allow list** reason in the audit event.
-
-## The two modes
-
-| Name      | Default | Description                                                                                                       |
-| --------- | ------- | ----------------------------------------------------------------------------------------------------------------- |
-| Allowlist | off     | Only the listed packages install; everything else is rejected. Use when a regulator names the approved libraries. |
-| Denylist  | on      | Every package installs except the listed ones. Use when a small set is known-bad and the rest is trusted.         |
-
-## The four lists
-
-Each mode reads from two lists — Python and Node. One package per line, or comma-separated. Version constraints are stripped automatically (`pandas==2.1` matches `pandas`), so the policy is name-based and survives library upgrades. Scoped Node packages (`@scope/pkg`) are supported.
-
-The mode is global: in allowlist mode both languages read their allow lists, in denylist mode both read their deny lists. The lists themselves are per language, so Python and Node each keep their own set.
-
-## The tester
-
-The Test panel on the same page lets you paste pip or npm specs and see whether each one would pass under the current draft. It uses your unsaved edits, so you can iterate before clicking Save. Each spec is parsed, stripped of its version constraint, and matched against the lists; the panel reports **Allowed** or **Denied** with the reason — matches-the-allow-list, not-on-the-allow-list, matches-the-deny-list, not-on-the-deny-list.
-
-## Network egress and skills
-
-The package policy gates _what_ runs in the sandbox. The same sandbox runs skill scripts — see the [Skills concept](/platform/agents/skills) page. Outbound network from sandbox code is open by default, with cloud-metadata and private-range targets always blocked; on self-hosted deployments the operator can restrict it to a hostname allowlist at the deployment level — the walk lives in [Hardening](/self-hosted/operate/security/hardening). Treat publishing a skill with a script as widening the trust surface for every agent that picks it up; the package policy and the deployment's egress policy together decide what the script can do.
-
-## Where this fits
-
-Run-code policy is the gate on the sandbox that backs both the Run code tool and skill scripts. The companion concept is [Agent skills](/platform/agents/skills) — it covers when to publish a script as a skill, and why the package policy is the load-bearing gate. The companion governance page is [audit logs](/platform/admin/governance/audit-logs) — every denied package install lands there with the spec and the reason.

 ## Video-link ingestion (yt-dlp)
 
 When Tale ingests a video link, it fetches the transcript for the agent. YouTube blocks automated access from datacenter/server IPs, so this can fail on a cloud deployment. The deployment ships a PO-token provider wired up by default (see [Video ingestion](/self-hosted/configuration/video-ingestion) for the full picture); the options below are optional overrides and escalations. None guarantees a bypass — a clean egress IP is the single biggest lever. Read by the backend worker and re-read on each ingestion, so a change takes effect without a restart.

-Politique run-code est la surface où tu décides quels paquets Python et Node la sandbox peut installer à l’exécution. Les skills avec scripts et l’outil Run code tournent tous deux dans la même sandbox ; cette politique est la couture unique où tu serres ou desserres ce qu’ils peuvent installer.

-
-Le mode par défaut est **Liste de blocage** avec liste vide, ce qui veut dire que tous les paquets sont installables. Pour passer à un ensemble curé, ouvre **Paramètres > Gouvernance > Paquets run-code**, change le mode en **Liste d'autorisation** et énumère les paquets de confiance sous **Liste d'autorisation Python** et **Liste d'autorisation Node**. Enregistre et la prochaine exécution sandbox qui demande un paquet hors de la liste échoue avec la raison **absent de la liste d'autorisation** dans l’événement d’audit.
-
-## Les deux modes
-
-| Nom                  | Par défaut | Description                                                                                                                            |

-| Liste d’autorisation | off        | Seuls les paquets listés s’installent ; tout le reste est rejeté. À utiliser quand un régulateur nomme les bibliothèques approuvées.   |
-| Liste de blocage     | on         | Tous les paquets s’installent sauf ceux listés. À utiliser quand un petit ensemble est connu mauvais et que le reste est de confiance. |
-
-## Les quatre listes
-
-Chaque mode lit deux listes — Python et Node. Un paquet par ligne, ou séparé par des virgules. Les contraintes de version sont retirées automatiquement (`pandas==2.1` correspond à `pandas`), donc la politique est basée sur le nom et survit aux montées de version des bibliothèques. Les paquets Node scopés (`@scope/pkg`) sont pris en charge.
-
-Le mode est global : en mode allowlist les deux langages lisent leurs listes d’autorisation, en mode denylist les deux lisent leurs listes de blocage. Les listes elles-mêmes sont par langage — Python et Node gardent chacun leur propre jeu.
-
-## Le testeur
-
-Le panneau Test sur la même page permet de coller des spécifications pip ou npm et voir si chacune passerait sous le brouillon courant. Il utilise tes modifications non enregistrées, donc tu peux itérer avant d’enregistrer. Chaque spécification est parsée, dépouillée de sa contrainte de version et confrontée aux listes ; le panneau rapporte **Autorisé** ou **Refusé** avec la raison — correspond-à-la-liste-d’autorisation, absent-de-la-liste-d’autorisation, correspond-à-la-liste-de-blocage, absent-de-la-liste-de-blocage.
-
-## Egress réseau et skills
-
-La politique de paquets régit _ce qui_ tourne dans la sandbox. La même sandbox fait tourner les scripts de skill — voir la [page concept Skills](/fr/platform/agents/skills). Le réseau sortant depuis le code sandbox est ouvert par défaut, les métadonnées cloud et les plages privées étant toujours bloquées ; sur les déploiements auto-hébergés, l’opérateur peut le restreindre à une allowlist d’hôtes au niveau du déploiement — la marche à suivre vit dans [Durcissement](/fr/self-hosted/operate/security/hardening). Traite la publication d’un skill avec script comme un élargissement de la surface de confiance pour chaque agent qui l’adopte ; la politique de paquets et la politique d’egress du déploiement décident ensemble ce que le script peut faire.

 ## Ingestion de liens vidéo (yt-dlp)
 
 Quand Tale ingère un lien vidéo, il récupère sa transcription pour l'agent. YouTube bloque l'accès automatisé depuis les IP de centres de données/serveurs, ce qui peut échouer sur un déploiement cloud. Le déploiement embarque par défaut un fournisseur de PO tokens câblé d'origine (voir [Ingestion vidéo](/fr/self-hosted/configuration/video-ingestion) pour le tableau complet) ; les options ci-dessous sont des surcharges et des escalades facultatives. Aucune ne garantit un contournement — une IP de sortie propre est le levier le plus important. Lues par le backend worker et réévaluées à chaque ingestion, donc une modification prend effet sans redémarrage.

Claim = org-scoped LRU walk (FOR UPDATE SKIP LOCKED, `last_used_at_ms` stamped so concurrent reach-outs rotate); report `blocked` cools, the third strike expires (`ok` resets); the `browser.sweep` 10-min schedule expires past-TTL rows, recovers cooled ones after the 30-min quiet period, prunes 7-day-expired rows. Jars JWE-encrypted at rest (the reused `encryptString`; the ingest engine decrypts with the reused `decryptString`) and never returned by any read (the listing is masked metadata). The import write keeps the 0.4 gate exactly: the pure `decideInstanceAdmin` over the caller's member rows — org-admin required, plus the `TALE_DEPLOYMENT_CONFIG_ADMINS` editor allowlist for writes (empty allowlist locks all imports). The video ingest shim's claim/report nulls replaced with the real verbs. Routes `/api/app/browser-sessions` (masked list = org member; import = the gated write). Integration: allowlist 403 → 201, masked listing (raw body carries no jar bytes), LRU A→B→A rotation with the jar decrypting back, blocked×3 → expired vs blocked×1 → cooling → empty pool, aged quiet

Governance seams allow-all/no-op until governance ports (checkModelAccess, context cap, recordConnectorUsage, per-subject read matrix). inc 30: the THREAD SURFACE — migration 0023 (surface columns on the `thread_metadata` sidecar: archive/pin/read-watermark/share/capabilities/effort/branch lineage; partial-unique share_token) + `domains/chat/threads.ts` porting `threads.ts`/`thread_lifecycle.ts`/`project_threads.ts`/`search.ts`: pinned-float active list + keyset-paged archived list, owned/project-shared reads (real `checkProjectAccess` gate — the create route's existence-only check upgraded too), capability/effort/rename/pin/read/archive/file-to-project metadata edits (recency preserved; archive audited), org-internal share links (256-bit token IS the URL, `sharedAt` snapshot cut, token survives unshare), branch-at-a-message (history ≤ fork copied, lineage stamped), trash/restore with the generating guard + `branch_root_id` cascade (audited; legal holds ride the retention port; the purge sweep rides retention too), the project Chats tab (mine + shared-with-project), and the 0.4 bounded palette search (40×30 recency scan, AND-token match) over the derived `text` column. TITLE GENERATION reused whole: `generateThreadTitle` hoisted onto the chat shim (+`getChatModelInternal`/`setThreadTitleInternal` handlers) behind the `chat.generate_title` job, auto-enqueued by the TurnStore's first-user-message append on an untitled thread (the same seam also stamps `last_reply_at` for assistant rows and bumps the branch ROOT's recency); the fill-only write never clobbers a rename. NOTE: sandbox execution mode is DEAD in 0.4 (#2877 made chat plain-conversation-only) — dropped from the map. inc 31: EDIT/REGENERATE LINEAGE — migration 0024 (branch_parent_id / branch_fork_sequence / branch_selections) + the branch half of `threads.ts`: `branchForEdit` copies strictly BEFORE the edited user message, `branchForRegenerate` copies THROUGH the prompt it re-answers (chat appends are flat, so `order` IS the 0.4 sequence and copies stay gap-free from zero), both as HIDDEN siblings inheriting agent/capabilities/project on the root's lineage; `listThreadBranches` + the bounded root-side selection map; the chat shim's placeholder `getThreadLineageIds` replaced with the REAL lineage walk, so a turn's retrieval scope (attachment binds included) widens across every sibling. inc 32: AUTO ROUTING live — `modelSelection: 'auto'` was already inside the reused `executeTurn` (`resolveChatModel` resolves a concrete pair before anything binds); what landed is its two missing shim reads (`listActiveCredentialFactsInternal` over `app.provider_credentials`, `resolveModelGovernanceInternal` → the new `resolveModelGovernanceForUser`: the `default_models` pin dropped when `model_access` would refuse it + the accessible catalog subset, over the hoisted pure `filterAccessibleModels`/`findApplicableModelRule`) and the send lane accepting Auto (modelId optional, the engine enforces the XOR). MEMORIES — migration 0025 `app.memories` + `domains/chat/memories.ts`: approval-gated (pending until the OWNER approves; retrieval sees `approved` only, (org,user)-scoped), proposing audited (`memory.save`, category `ai`); surface routes (list/save/review/search); the `memory.save`/`memory.search` TOOL lane stays unwired exactly like 0.4's three-tool executor. DEFERRED SENDS — 0025 `app.deferred_sends` + `domains/chat/deferred-sends.ts`: park-on-Send while media index (readiness matrix over `file_metadata.rag_status`/`transcription_status`; images never gate; video-link legs read absent rows as "erased — proceed" until that domain lands), the 0.4 scheduler chain replaced by the self-chaining `chat.deferred_send_poll` job (aged 3s→15s backoff), claim → the turn runs under the stored identity → the row settles in a `finally` (the 0.4 mop-up posture); tray list + waiting-only cancel + XOR/cap guards. FIXED EN ROUTE (platform-wide): the worker's `notifyPollingIntervalSeconds` sat at 30s — NOTIFY fires on INSERT, never when a delayed job's `startAfter` passes, so EVERY delayed self-chain (deferred sends, automation polls) crawled at up-to-30s per hop; now 2s to match the polling interval. inc 33: the COMPOSER SURFACE — `domains/chat/composer.ts`: the model picker's listing over the SAME connector walk a turn resolves (`walkChatCatalog` on the chat shim; the per-hit projection hoisted as the pure `collectComposerOptions` and REUSED — voice availability riding the same walk), governance-filtered server-side (`getAccessibleModelsForUser` — the picker never even sees a hidden model; the turn re-checks at send), the managed-harness roster (reused loaders + inlined icons), and the capability menus (project/automation skill listings through the reused file-layer viewer with the project's OWN team scope; connectors return the honest empty until the connector-credentials domain lands). Routes: `/composer/models`, `/composer/project/:id/capabilities`, `/composer/automation-capabilities` (developer-gated). PENDING: arena, voice actions (tts/dictation), queue steering, questions surface, trash purge sweep (retention), memory tool lane (with the capability executor, if 0.4 rewires it); inc 97: `getOrgChatHealth` twin (`domains/chat/health.ts`) — assistant-turn fold over one bounded `app.messages` page (errors classified via the shared chat-error decoder, blocked/tokens/series, model+agent breakdowns, agent attribution joined from `thread_metadata` NOT `threads`) behind admin/developer `GET /chat/health`. inc 98: the chat feature's LAST websocket surfaces — QUESTIONS (`domains/chat/questions.ts`: the pending set on `app.approvals` `human_input_request`, one per thread with supersede-on-ask; "still outstanding" DERIVED from the thread — any user message newer than the ask settles it, so no close-write can strand the panel; resolve stamps the transcript's `human-input` part best-effort) and ARENA (`domains/chat/arena.ts`: migration 0054 puts the 0.4 `arena` marker on `thread_metadata`; ensure copies A's bounded history into a hidden B stamped `branch_root_id` but never `branch_parent_id`, idempotent + half-open heal; settle CHOOSES the surviving thread — loser hidden+archived, a winning B graduates — and a verdict inserts the analytics-contract feedback row; the fanned turn busy-gates BOTH columns then runs two `runChatTurn`s concurrently with per-side error rows). Migration 0054 also narrows `message_feedback`'s (message_id, user_id) uniqueness to a PARTIAL index `WHERE metadata IS NULL`: votes keep upserting, arena verdicts stack per run (the 0.4 insert-per-settle contract). FRONTEND: `chat.ts` grew the question/arena/share-status rows, `arena-actions.ts` left the Convex client entirely, and the seam's watch-lane invariant tests re-pointed at a still-unmigrated ref — **every chat read is HTTP now**. BROWSER: Arena Mode toggled in a live thread → pair created over pg → one prompt fanned to two fake-provider models → both columns streamed their own answer → 'B is better' settled (URL swapped to the winner, loser hidden+archived) → the verdict appeared on the feedback metrics page's matchup table. inc 111 ledger truth pass — the row's old PENDING list is stale or empty: ARENA and the QUESTIONS surface landed in inc 98, VOICE actions (synthesize/chunks/dictation/overrides) in inc 78 with the dictation door on `POST /files/dictation`, the TRASH PURGE sweep belongs to retention (`purgeThreadLineage`, wired into its daily cleanup), and QUEUE STEERING has no server lane to port — the composer's send queue is client-side and the mid-turn steer that does exist is the task-agent lane (inc 110). The MEMORY TOOL lane was conditional on 0.4 rewiring its capability executor, which never happened: the chat tool wire is exactly `rag_search`/`rag_fetch`/`web_fetch` (with `ask_question` deliberately off it), so there is no memory tool to port. Every chat read is HTTP; the row's remaining seam is the `@automation` run trigger, tracked on the automations row. inc 112: row CLOSED — every chat read is HTTP, arena/questions/voice/purge all shipped, and the remaining `@automation` trigger is tracked on the automations row

The OAuth doors keep the 0.4 wire path (`/api/cloud-import/oauth2/{start,callback}` + the `/http_api` proxy alias — vendor app registrations carry the callback): start is session + knowledgeWrite gated with the Entra-tenant fallback off the org's SSO issuer; the callback consumes the one-shot state, exchanges server-side, fetches the account label best-effort, and seals the grant. `resolveCloudAccessToken` = the resolve twin (decrypt → refresh at the 5-min buffer → re-seal; refresh-less expiry and failed refresh mark `needs-reauth`). Surface `/api/app/cloud-import` (list own grants metadata-only, revoke drops the sealed payload).

Realtime hints on every write. inc 38: the TASK EMITTERS — `notifyTaskAssigned` (the previous human carrier told with `undoes` so assign-then-unassign leaves nothing; the new human assignee subscribed + told, never for self-assignment; agents/apps have no inbox), `notifyTaskStatusChanged` (subscribers minus the actor, wired into BOTH status writers — the human route and the trusted agent door), `notifyTaskComment` (commenter follows, mentioned humans get the precedence 'mention' row, other subscribers `task_commented`; wired into `addTaskComment` — mention EXTRACTION still rides the mention-directory port), and the creator auto-follow at `createTask`. inc 39: AGENT-ASK ESCALATIONS — `notifyAgentQuestionAsked` fans `agent_escalation` rows to everyone who can SEE the run's project (admins ∪ team members; org-wide project = all members; no project = org admins; 500 cap), wired into the tool door's `createAskForExec` (create AND fold — with a task subject the `question` dimension rewrites the unread row; a no-task ask has no collapse subject, the 0.4 posture) and dismissed transactionally by `answerAsk`/`closeAsk` (ONE SQL by `params->>'askId'` — tighter than 0.4's capped per-member walk). Plus the PENDING-REVIEWS FACET: `collectPendingReviewsForProjects` (bounded org-level read over `metadata->>'projectId'`) behind `GET /tasks/pending-reviews` for the board chips (registered BEFORE the `/:taskId` wildcard). inc 54: the debounced EMAIL sink — every actionable write in `writeCoalescedNotification` bumps the row's `email_epoch` (migration 0038) and enqueues `notification.email` (retryLimit 0) one debounce window out (60s; env-tunable `NOTIFICATION_EMAIL_DEBOUNCE_MS`); the job (`domains/collab/email-sink.ts`, the 0.4 `deliverActionableEmailAction` twin) re-reads the row and sends only when it is still unread AND the payload epoch is current — the epoch fence REPLACES the 0.4 cancel+reschedule (a rewrite's older job no-ops, its newer job carries the final state; an undo deletes the row; a read row mails nothing), safe under at-least-once delivery. Delivery: recipient email from the auth `user` row, the tri-state `actionable_email` pref (absent = ON), mailbox picked by the REUSED `pickSendableMailbox` over active mail credentials (the pure pick/input helpers HOISTED out of `send_actionable_email.ts` into `actionable_email_input.ts`; `buildPersonalNotificationUrl` hoisted to `personal_notification_url.ts` — both stacks import the seams, 0.4 suites stay green), org default locale from `organization.metadata`, `renderActionableEmailContent` REUSED, and the send through the connector door as the system caller (imap-smtp `notificationSender` From rewrite). Integration: burst → ONE email with the final state + deep link + `notification@` From, read/undo/pref-off all silent; the harness now installs a run-wide default fake mail transport (no itest job ever opens a real IMAP/SMTP connection) and drains pending notification emails before every SMTP-counting check. PENDING: mention directory + description mentions, automation alerts, attention summary, deadline crons. inc 106: the MENTION lane + the return loop. `domains/collab/mention-directory.ts` builds the project-scoped directory on pg with the 0.4 rules intact — only members who can ACCESS the project are mentionable (through the SHARED `hasProjectAccess`, so the mentionable set can never disagree with who can open the task), handle precedence is insertion order (listed slugs → deployed automations → the project's agent INSTANCES last, so an instance shadows a same-named retired slug and the mention reaches the live lane), a non-`restricted` project is PERMISSIVE (an unclaimed token reads as an agent handle), and every leg degrades on its own. The scanning itself is REUSED from `tasks/mentions.ts` — one grammar for `@handle`. Task comments now resolve mentions for real (the TODO is gone): the resolved list drives the existing notify fan-out (bell + auto-subscribe with reason `mention`) and rides the meta row, while tokens that matched nobody go back to the composer so the author is told instead of silently ignored. `getMyAttentionSummary` + `GET /collab/attention` complete the return loop — unread split actionable/total by the shared predicate, task reviews waiting on THIS person, and their own open assignments merged into one id set so a task that is both counts once; `projectId` scopes it to one board. PENDING: the @automation RUN TRIGGER and steering a mention into a live agent run (they belong to the automations/agents lanes). inc 113 CLOSES the row: the `@automation` RUN TRIGGER ships — @-ing the automation that OWNS a task starts its task workflow (which re-reads the timeline, this comment included), while a plain comment or a mention of any OTHER automation starts nothing. Ownership is the 0.4 three-shape rule (app-assigned names it, app-created names its creator, externally-mirrored matches through the deployed version's task contract); the gate is WRITE access (commenting is read-level, running a workflow is an edit) and one engine per task across BOTH lanes. The start is ENQUEUED, not inline: the comment must commit first, and 0.4 scheduled it for the same reason. Steering a mention into a live agent run landed in inc 110. TWO 0.4 behaviours the port had dropped are back: the run trigger gates on the comment's AUTHOR TYPE (0.4 reached it only from `applyUserTaskComment`; 0.5 merged the user and agent doors into one `addTaskComment`, so an agent- or workflow-authored comment naming the owning automation restarted the engine that wrote it — a sequential loop of metered agent turns the one-live-run guard cannot see, because it blocks a CONCURRENT second start, not a later one), and `editTaskComment` RE-RESOLVES mentions (it wrote only `edited_at_ms`, so editing a comment to add `@someone` notified nobody and the stored set went stale; the fan-out is `addedMentions` only, never the full set). Description mentions (`updateTask`) stay PENDING |

Integration: create against the real shipped imap-smtp connector (defaults + From-mirroring asserted), masked listing with a secret-leak sweep, name clash 409 / unknown connector 404 / wrong method 400, the resolve seam (secrets + config + computed Basic header, name ref), promote → delete-promotes-oldest, disabled refusal. PENDING: oauth2 grant flows (`storeOauth2Credential` + refresh — ride the per-connector OAuth routes), 0.4-parity NO audit rows (none in 0.4 either)

Migration 0044 `app.google_drive_sync_configs` (same substrate as 0043). Google deltas carried by the adapter + the REUSED `convex/google_drive` modules: GRANT-ONLY tokens (`resolveCloudAccessToken('google-drive')` — no login-linked shortcut), Drive v3 listings (`q='<parent>' in parents`, pageToken paging with the same throw-on-page-cap so a short read can never prune), md5Checksum hashes, Workspace-native Docs/Sheets/Slides refused (browse hides them, the sync listing skips them, metadata refuses the binary import), no SharePoint analogue. Jobs `google_drive.sync_scan` (cron staggered `7-59/15`) + `google_drive.sync_config` (retryLimit 0, claim-fenced). Routes `/api/app/google-drive` (list-files, import, sync-configs/:id/cancel; org-member, no rate rules = 0.4 parity). Integration: fake Drive v3 — grant browse (native hidden, folder selectable), folder+single-file sync import with nested paths, hash-skip idle, drift (md5 update-in-place with history, prune+reap, a NEW native file never imported), single-file 404 → `source-deleted`, the cross-provider trash hook flipping a google config, second-pair scan enqueue + cancel door

-| governance            | done                               | inc 23: policy ENFORCEMENT over governance files — the pure evaluators REUSED (`evaluateModelAccess`/`evaluateFeatureFlags` hoisted from the 0.4 modules; 0.4 suites still green) hosted on the 0.5 policy reader; the chat/tool shims' allow-all seams are now REAL verdicts (model access refuses at the turn boundary with the 0.4 wording, feature-flags `maxContextTokens` caps the window); usage metering = `app.usage_ledger` (migration 0020, the 0.4 three-period buckets as one `ON CONFLICT` increment on a coalesce-keyed unique index) fed by the chat turn ledger + the connector-tool dispatch. PENDING: budget ENFORCEMENT call sites (rules engine is reused-ready; record-only today), retention sweeps, erasure cascades + DSAR, legal holds, moderation/guardrail policies, session-idle enforcement, competence/review policies, usage analytics surfaces inc 41: LEGAL HOLDS — migration 0029 (`legal_holds` + `legal_hold_release_requests`; the 0.4 `activeLegalHoldClaims` OCC table collapsed into a partial-unique active-per-target index, rule 5) + `domains/legal_holds/*`: placement (org 'nuclear halt' / userMembership custodian cascade; cross-org target refused; label snapshot; audited), the maker-checker release (a DIFFERENT admin approves — `TALE_LEGAL_HOLD_SINGLE_ADMIN_OK` is the single-admin escape with the loud self-approved audit subtype; 5-min anti-chaining delay; requester-still-admin recheck; 24h cooldown `TALE_LEGAL_HOLD_RELEASE_COOLDOWN_HOURS`), the daily `governance.effect_hold_releases` sweep, and the `assertNotHeld` guard WIRED into thread trash (+ restore freeze via loadActiveHolds) and document trash. inc 42: the RETENTION FRAMEWORK — migration 0030 `retention_applied_bounds` (the runtime clamp source: operator file/env edits take effect only when an admin APPLIES; audited) + `domains/retention/service.ts` reusing the pure `retention_floors` whole (file × env tightening via `applyEnvTighteningAll` — the file must declare every category, compliance floors bind — and `clampConfigToBounds` over the snapshot), the daily `governance.retention_cleanup` dispatcher (per-org: `retention_policy` file clamped to the applied row; holds pre-fetched once; one org's failure never starves the fleet; `TALE_RETENTION_DISABLED` kill-switch) and the phase-1 category sweeps (usage ledger, message feedback, both notification tables — custodian-held users' rows spared, org hold freezes the run; DELIBERATE simplification: the row-level two-pass grace collapses to delete past retention+grace — same end state; the visible-trash pass belongs to the thread/document phase); admin surface `/api/app/retention/bounds{,/apply}`. inc 43: RETENTION PHASE 2 — documents (Pass A expire-to-Trash under grace, Pass B purge: corpus entry via the reused `deleteKnowledgeDocument` keyed by the file REF (since folded into `deleteKnowledgeDocumentsBatch` in `core/legacy/knowledge_delete.ts`) + S3 blob + file rows + dependent knowledge-entry chains + the row), chat history (Pass A expire, Pass B purges the WHOLE lineage — messages/generations/feedback/sidecars/threads; chat-type only, task discussions never enter; grace-0 also purges standing trash — the 0.5 posture), contacts (lifecycle two-pass), agent runs (settled past window, starter custodian-spared), TEMP files (loose user/agent uploads with no document binding; ≤0 hours reads as OFF, never delete-now), and AUDIT LOGS chain-consciously: PREFIX-ONLY deletion that STOPS at the first custodian-held actor's row (spoliation duty wins; never a mid-chain hole) — and the chain VERIFIER now anchors on the first REMAINING row's stored previous_hash instead of genesis (required for any post-retention verify; the tale CLI's verify must match at cutover). inc 44: GDPR ERASURE (Art 17) — migration 0031 `gdpr_erasure_requests` (the durable receipt: lawful ground, 30-day SLA + single Art 12(3) extension columns, cooling-off `effective_at`, outcome counts; one LIVE request per subject via a partial-unique index) + `domains/erasure/service.ts`: `requestErasure` (admin-only, SELF-erasure refused — it would wipe the filer's own audit evidence; denials audited; `governance:dsar_request` rate limit; the hold gate AFTER the insert so an Art 17(3)(e) refusal is a durable 'blocked' receipt), the cascade job `governance.process_erasure` fired after the org's `dsar_governance` cooling-off (hold gate re-checked at execution; per-pass counts; failures → 'partial' with a retry path): threads (reused lineage purge), documents (reused corpus+blob purge), loose uploads, preferences, bells, subscriptions, feedback, memories, usage ledger, and the AUDIT SCRUB — rows KEPT (Art 17(3)(b)), PII columns + peppered hashes blanked, `pii_scrubbed` marks the intentional divergence (the 0.4 signed-checkpoint window collapses to this flag + the receipt, rule 5) and the chain VERIFIER skips recompute on scrubbed rows while still checking linkage; cancel inside the cooling window; retry for blocked/partial/failed. inc 90: the GOVERNANCE SETTINGS CORE — NEW `domains/governance/routes.ts` (`/api/app/governance`): `GET/POST /policies/:policyType` (the 0.4 `getPolicy`/`saveGovernancePolicy` pair — member-readable set vs admin, the SPECIAL-WRITE refusal for retention/dsar, schema-validated writes through NEW `lib/governance-policy-write.ts` reusing the 0.4 file helpers whole: history snapshot → atomic yaml → legacy-json removal → org-config cache bust; created/updated audit rows with config diffs + `governance_policy` hints), `GET /my/feature-flags` (resolved flags + the composer's `inputGuardrailsActive` over the three guardrail policies), `GET /my/budget-status` (exceeded via the hoisted budget twin, near-limit warnings via the now-exported `collectWarnings` scoped to the selected team — the 0.4 display rule), `POST /models/accessible` (the model-access filter), and the ADMIN TRASH — NEW `domains/governance/trash.ts`: soft-deleted rows across the pg lifecycle tables (documents/file_metadata/contacts/conversations/message_feedback/automation_runs/thread_metadata) with owner names, composite type-ordered keyset cursor (bridged to the 0.4 `{ts,id}` cursor by riding the type inside the id), and `restoreSoftDeletedRow` (per-type live value, audit + per-type hint; 0.4 types with no pg trash stop answer empty by design). Frontend: 5 read rows (getPolicy(row-shaped {key,config})/flags/budget-status/accessible-models(POST-backed read)/listTrashedRows) + 2 write rows (saveGovernancePolicy/restore). Integration 169/169 (verify158: idle-timeout write→read 45, unknown-type 400, special-write 400, flags+budget+models, trash contact → listed → restored → 404 replay).

LEGAL-HOLD SETTINGS SURFACE: matters CRUD + `closeLegalMatter` FAN-OUT (one pending release request per linked active hold via one anti-join INSERT..SELECT; dual-control survives; idempotent close answers 0), `placeLegalHold` grew `matterRef` (validated), the full 0.4 ITEM VIEWS (holds list w/ status+targetType filters, resolved placer/releaser names + matterName; matters w/ createdByName + linkedActiveHolds; release requests w/ status filter + composite keyset (`requested_at_ms,id`) + `nextCursor` envelope; by-target grew matterRef; reject records `reject_reason`). ERASURE SURFACE COMPLETION: `extendErasureDeadline` (Art 12(3): 1..60 int, once-only, pre-lapse, terminal refused) + detail receipt `GET /:requestId` ({request — counts jsonb mapped onto the 0.4 fields + whole as perCategorySnapshot, threads_targeted captured at FILE time, resolved names — , auditEntries: the gdpr_erasure% trail}) + summaries keyset lane w/ `statuses` filter; ERROR-CONTRACT PARITY sweep: `ALREADY_PENDING` {requestId,status} answered OUTSIDE the aborted tx (unique-violation aborts — lookup needs a fresh connection), hold-block now REFUSES 409 `LEGAL_HOLD_BLOCKS_ERASURE` {requestId,orgHeld,userCustodianHeld} AFTER committing the blocked receipt + audit, `NOT_CANCELLABLE`/`cannotCancelAfterCooldown`/`NOT_RETRIABLE` split per the 0.4 codes, audit actions renamed to the 0.4 set (`gdpr_erasure_extended/cancelled/retried/executed`) so the drawer timeline i18n resolves; `ErasureError` grew a data bag the route spreads. DSAR POLICY: `getDsarPolicyForUi` + `proposeDsarPolicy` (tighten→file now; loosen→staged 24h via the reused `isLoosening`; PENDING_CHANGE_EXISTS) + cancel-pending. RETENTION TAIL: `POST /policy` (full 13-category bounds validation + 7-day shortening cooldown staging + first-enable bounds seed), pending-change GET/cancel (cancel REVERTS the yaml from the old-config snapshot), `GET /bounds/catalog` (the 0.4 `getRetentionBoundsAction`: `applyEnvTighteningAll` + `isRetentionDisabled`; missing config = empty bounds, not an error), `GET /bounds/proposal` (effective×applied hash diff + impact preview; applied/rejected-hash silencing) + `/bounds/reject` + `/bounds/apply` grew `proposedHash` OCC (409 STALE_PROPOSAL); the SWEEP now overlays a live pending shortening with max(old,new) per numeric key — reductions wait out the cooldown, extensions apply immediately — onto a COPY of the cached config (mutating the shared cache froze pre-cooldown values forever; caught by the new probe). MODERATION SECRET: save (secret_box) + `GET /moderation/secret/status` (masked preview / rotation notice / null) + the offline test stub (400 MODERATION_TEST_OFFLINE).

One deliberate divergence from 0.4: an EXPIRED live row is retired inside the grant transaction, so a re-grant after expiry is an ordinary act instead of a 409 the admin cannot resolve. `checkReviewPolicyForResponder`loses its fail-closed stub — an org with`requiredCompetences`set could previously have NOBODY respond to a review — and now stamps`competenceRecordIds`on both the approval response and the`task.review_responded`audit row, so a later auditor sees WHICH grant admitted the reviewer. Admin routes:`GET/POST /governance/competences`, `POST /competences/:id/revoke`(reads org-member: a refused responder must be able to see why). No frontend work — 0.4 has no competence UI either; the only app-side trace is`reviewPolicyErrorMessage`, already localized. Probed end-to-end through the REAL review door: holder approves (200, grant stamped on approval + audit) → revoke → the same reviewer is refused 403 `REVIEW_COMPETENCE_REQUIRED` naming the missing slug.

Budget ENFORCEMENT is CLOSED as parity, not built:`checkBudgetForRequest`has no callers anywhere in 0.4 — the only live enforcement point is TTS, which 0.5 already has, plus the status read.`getGuardrailStats`shipped in inc 97 inc 115: **competence records** — the last governance hole closed.`domains/governance/competence.ts` ports the 0.4 register verbatim in Postgres terms: a partial unique index (`WHERE revoked_at_ms IS NULL`) IS the "one live grant per (member, competence)" rule (0.4 scanned and compared), a revoked row is RETAINED as the trail behind every review it admitted, non-admin writes are refused AND audited (`competence_grant_denied`/`_revoke_denied`), and a grant to a non-member refuses (`COMPETENCE_USER_NOT_MEMBER`). One deliberate divergence from 0.4: an EXPIRED live row is retired inside the grant transaction, so a re-grant after expiry is an ordinary act instead of a 409 the admin cannot resolve. `checkReviewPolicyForResponder`loses its fail-closed stub — an org with`requiredCompetences`set could previously have NOBODY respond to a review — and now stamps`competenceRecordIds`on both the approval response and the`task.review_responded`audit row, so a later auditor sees WHICH grant admitted the reviewer. Admin routes:`GET/POST /governance/competences`, `POST /competences/:id/revoke`(reads org-member: a refused responder must be able to see why). No frontend work — 0.4 has no competence UI either; the only app-side trace is`reviewPolicyErrorMessage`, already localized. Probed end-to-end through the REAL review door: holder approves (200, grant stamped on approval + audit) → revoke → the same reviewer is refused 403 `REVIEW_COMPETENCE_REQUIRED` naming the missing slug.

 | http_connectors       | done                               | inc 102: the OAuth2 CONSENT FLOW ported — migration 0055 (`connector_oauth_states` keyed by the state HASH; `connector_team_routes` with `team_id` as the PRIMARY KEY, so "one workspace, one organization" is an invariant the database holds instead of 0.4's read-two-and-refuse) + `domains/connectors/{oauth,oauth-routes}.ts`. Every security-critical module is REUSED verbatim — the opaque single-use state (`oauth_state.ts`), PKCE S256 (`enterprise_sso/pkce.ts`), the deployment-fixed redirect URI + env-only app credentials (`deployment_config.ts`), the authorize-URL builder with its vendor quirks, the scrubbed server-to-server exchange, and the HTML error pages — so the flow's four rules hold by construction. Single-use becomes `DELETE … RETURNING` (one statement, so two replayed callbacks cannot both observe the row); the catalog stays the only truth for endpoints and scopes. `GET /api/connectors/oauth2/start` is session+ability gated (`developerSettings`, the same capability a credential write needs), `/callback` is authorized by its state row alone. Probes drive the whole flow against a fake vendor: anon 401 / foreign-org 403 / unknown-connector 400, the row stores only the hash, a declined callback BURNS the state so a replay exchanges nothing, the exchange sends the PKCE verifier and the byte-identical redirect URI, the credential lands encrypted (a plaintext-token scan returns 0) with the workspace claimed, a foreign claim is refused, and a vendor-rejected exchange writes nothing. PENDING: Slack events inbound (signature + routing + `identities`). inc 103: SLACK EVENTS INBOUND — `domains/connectors/slack-events.ts` re-hosts the 0.4 handler with its three constraints intact and its verification REUSED (`slack_signature.ts`: raw-byte base string, constant-time compare, five-minute replay window; the raw text is read before anything inspects content). Unconfigured signing secret = the endpoint stays SHUT (503), never processes unauthenticated input; failures are throttled per client IP and tokens are consumed only on FAILURE, so a forged flood is bounded while genuine deliveries are never rate-limited into a non-2xx. The tenant comes from `team_id` alone (an unmapped workspace 404s, never falls back to "the only organization"), and the verified event is ENQUEUED — pg-boss `short` policy + a per-delivery singleton key, so Slack's retry of a still-queued delivery collapses instead of replaying the conversation (0.4 scheduled one action per delivery and only documented the dedup key; this is the same contract, enforced). Delivery still degrades to a logged handoff exactly as 0.4 does — the conversational surface that answers inbound messages is not wired to this lane in either version

The owner id is namespaced AND org-scoped, so it is the primary key and a row can never span tenants; a refresh that fetched NOTHING deliberately leaves `updated_at_ms` alone (resetting it on a failed fetch would suppress retries for the whole freshness window — the 0.4 rule, proven by a probe). `resolveExternalDisplayNames` takes a MIXED id list and answers only the external half, so a

PENDING: transcript RAG (tts), email-message (`msg:`) refs and queue-on-bind for emailed attachments (the CONVERSATION retrievable branch landed — `decideRetrievable` decides it from the caller's readable conversations, resolved per dispatch from the candidates' own; #3121 step 1), corpus status/repair surfaces, KNOWLEDGE_MIGRATIONS_DIR in the runner image (web corpus crawling landed with websites, inc 67) inc 93: the ADMIN CONFIG surface for the data-residency page — `domains/knowledge/admin.ts` (the 0.4 `knowledge/{actions,file_actions}` re-orchestrated; paths/schemas/history layout byte-identical via the reused `connection.ts` resolvers + file_io; the four-line serializers twinned): connection read/write (password sidecar: set/replace, empty-string REMOVES, absent keeps; org pool URL busted on change)/delete/probe (stored-password fallback + pgvector/ParadeDB hints), embedding read/write (SSRF-gated baseUrl; history snapshots)/delete, and `GET /embedding/recommendations` (direct-credential providers × shipped catalogs through the reused `pickEmbeddingRecommendations`). Routes on `/api/app/knowledge/*` behind the orgSettings write gate. Frontend: 3 ACTION_QUERY reads + recommendations + 5 writes. Probes: save→view hasPassword→LIVE pg probe ok (the itest DB itself)→embedding save/read→recommendations 200→both deletes revert to unconfigured. BROWSER: embedding form save → 'Configured' badge + `knowledge/embedding.json` on disk. inc 114 CLOSES the row. KNOWLEDGE_MIGRATIONS_DIR in the runner image was a REAL production bug and is fixed: `findMigrationsDir` falls back to walking up the module path for a repo checkout, which a container does not have, so preparing a new corpus (the deployment default on first boot, and every BYO per-org database) degraded to the "apply them yourself" remedy. The platform image now COPIES `services/db/migrations/knowledge-db` — into the builder stage (so the dev image inherits it) and into the runner — and names it in `KNOWLEDGE_MIGRATIONS_DIR` in both, with a guard test that fails if either copy or either env line disappears. The rest of the row's PENDING list names work that does not exist to port: TRANSCRIPT RAG is 0.4's OWN documented deferral (`transcribe_audio.ts`: "a deliberate follow-up … `transcriptRagStatus` stays unset") and 0.5 mirrors it exactly, including the captions branch that DOES index; the CONVERSATION/EMAIL retrievable branch is wired (`domains/conversations/search-chat.ts` behind the chat shim's `searchConversationsForChat`); and CORPUS STATUS/REPAIR is `corpus_status.getStatuses`, ported and consumed by the inc-104 RAG watchdog — no repair surface exists in either version
