+# External Codex publishing into the workspace
+
+Proposal, 2026-09-28. No endpoints, timers, or inference jobs in this document
+have been implemented. This supersedes the earlier proposal for app-managed
+inference and an application-owned life filesystem adapter.
+
+## Responsibility
+
+External Codex reads Beeper and the life filesystem, reasons about them, and
+maintains life under its existing Rensheng conventions. life remains the CRM
+source of truth. The workspace accepts structured results, persists and displays
+them, and records user decisions and requests. It does not need a new LLM loop,
+CRM compiler, or Markdown editing engine.
+
+```mermaid

+  T[Host timer or manual invocation] --> C[External Codex job]

+  P --> D[SQLite projections and user decisions]
+  D --> U[Home / Messages / CRM]
+  U -->|Requests and corrections| Q[Durable request inbox]
+  Q --> C
+```
+
+The existing Research chat can remain as-is. This design does not require
+removing that feature or putting its runtime in charge of CRM automation.
+Deterministic Beeper reads, live UI updates, and confirmed sends are ordinary
+application integration code; they do not imply app-owned inference.

+## What gbrain actually does
+
+Inspected revision: `e78f1c38b947b053f3a46881340f74f316be855a`.
+
+- Its [cron convention](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/skills/conventions/cron-via-minions.md)
+  assigns scheduling to the host. It explicitly describes a native cron
+  scheduler inside `jobs work` as not yet shipped.
+- [Minions workers](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/minions/worker.ts)
+  handle durable execution, leases and retries. Job idempotency and prevention
+  of overlapping runs are separate concerns.
+- [Autopilot](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/commands/autopilot.ts)
+  is a maintenance daemon, not a ready-made external Codex scheduler. The
+  built-in [subagent handler](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/minions/handlers/subagent.ts)
+  uses gbrain's own model/tool execution.
+- Its [page write operation](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/ops/pages.ts)
+  uses request receipts, expected revisions and transactional writes. These are
+  useful patterns for publishing into this app without importing its entire stack.
+
+## Scheduling proposal
+
+Use one external systemd timer and oneshot service, or the existing host scheduler
+if one already owns this workflow. Do not create schedules during research.
+Start with a morning brief and periodic daytime refresh; exact cadence and job
+timeout are deployment choices, not established product requirements.
+
+The runner sets an explicit working directory and `CODEX_HOME`, prevents
+concurrent runs, reads the app context revision, then invokes Codex to inspect
+sources and prepare a result. It publishes through the application API and keeps
+a private result file until acknowledgment so a network retry need not repeat
+inference. Do not put credentials in prompts or command arguments.
+
+Use separate identifiers for the scheduled occurrence and publish attempt. A
+retry of an unchanged result keeps its `runId`; regeneration after a conflict
+uses a new `runId`. Host logs expose started, finished and failed runs without
+dumping messages. The UI can show the last successful publication and source
+freshness; it should retain the previous good result when a new run fails.
+
+Beeper events can later mark work dirty and coalesce a wake-up. Do not start one
+Codex process per message. Natural-language requests can use the same external
+worker path; a future wake-up signal should only notify that worker, not execute
+browser-supplied shell text.
+
+## Write interface
+
+Start with HTTP and a small CLI wrapper that accepts JSON from a file/stdin.
+Add an MCP wrapper only if useful for tool discovery; it must call the same
+validated service. HTTP, CLI and MCP are access methods, not three state stores.
+Avoid direct SQLite writes and an arbitrary SQL, shell or filesystem tool.
+
+Proposed first contract, keeping the repository's camelCase JSON convention:
+
+| Method and path            | Caller                | Purpose                                                                 | Success                   |
+| -------------------------- | --------------------- | ----------------------------------------------------------------------- | ------------------------- |
+| `GET /api/agent-context`   | Agent credential      | Read revision, current projections, user decisions and pending requests | `200`                     |
+| `POST /api/agent-results`  | Agent credential      | Atomically publish a validated result and complete referenced requests  | `201`; exact replay `200` |
+| `POST /api/agent-requests` | Owner browser session | Persist a natural-language request or a requested life correction       | `201`; exact replay `200` |
+
+Browser snapshot reads use the same application service under owner session
+authentication. An optional `GET /api/agent-results/{runId}` receipt endpoint can
+be added if exact POST replay is insufficient. No public API version prefix is
+needed for this first coordinated client/server contract.
+
+The agent credential is limited to context reads and result publication. It must
+not approve a send, change login settings, or mark user decisions on the user's
+behalf. The existing session, Tailscale and Origin middleware does not accept
+this authentication flow today. Implement a narrowly scoped agent route branch
+that verifies its own credential; do not add these paths as unauthenticated
+exceptions or spoof a Tailscale identity. Use loopback locally, TLS remotely.
+
+### Result shape
+
+Illustrative payload, with fictional data:
+
+```json
+{
+  "runId": "morning-2026-09-29-attempt-1",
+  "jobKey": "daily-brief",
+  "expectedRevision": 42,
+  "generatedAt": "2026-09-28T23:00:00Z",
+  "sourceRefs": [
+    {
+      "id": "life-person-example",
+      "kind": "life",
+      "path": "people/example.md",
+      "contentHash": "sha256:example",
+      "observedAt": "2026-09-28T22:59:00Z"
+    }
+  ],
+  "brief": {
+    "date": "2026-09-29",
+    "timeZone": "Asia/Tokyo",
+    "text": "Start with the meeting reply.",
+    "evidenceIds": ["life-person-example"]
+  },
+  "people": [
+    {
+      "id": "person-example",
+      "name": "Example Person",
+      "context": "Discussing the next meeting.",
+      "evidenceIds": ["life-person-example"]
+    }
+  ],
+  "activities": [],
+  "replyDrafts": [],
+  "retractions": [],
+  "completedRequests": []
+}
+```
+
+`runId` and `jobKey` are required bounded strings; `expectedRevision` is a
+nonnegative integer from the last context read. All timestamps are RFC 3339.
+The server stamps `receivedAt` and authenticated publisher identity itself.
+Dates used for the home brief include an explicit timezone.
+
+People/activities/drafts are upserts with stable IDs, not position-based IDs or
+display names. People are projections of life, not independently maintained CRM
+facts. Activities use the typed contract below, with a title, references and
+evidence IDs. Drafts include canonical target/account/chat IDs, reply target,
+source message revision and candidate bodies/styles. Beeper evidence includes
+target/account/chat/message IDs and observation time; life evidence includes a
+relative path and content hash. A Git revision alone does not describe uncommitted
+life edits. Source references are data, never filesystem access instructions.
+
+The app validates structure, references, bounds and permissions; it does not
+infer whether a CRM fact is true. Publisher-supplied evidence is provenance, not
+proof that the app independently verified the original file or conversation.
+
+Omitted `brief` leaves the brief unchanged; empty arrays perform no upserts.
+Omission never deletes an existing item. Explicit typed retractions can withdraw
+agent suggestions but cannot delete user-owned decisions. Reject unsupported
+fields and nulls in this coordinated first version. Agree payload size, per-array
+limits and bounded context pagination when implementing; do not accept unbounded
+history or attachments through this endpoint.
+
+### Atomic publication and conflicts
+
+1. Scope receipts to authenticated publisher plus `runId`. Store a canonical
+   payload hash. A replay with the same payload returns the original receipt;
+   the same key with different content returns `409 idempotency_conflict`.
+2. Check replay before checking the expected revision. A successful retry must
+   still work after unrelated later UI changes.
+3. Validate the full result, check `expectedRevision`, write projections and the
+   receipt, and increment the context revision in one SQLite transaction.
+   A concurrent publish or user edit yields `409 revision_conflict` and no writes.
+4. User edits, dismissals, completions and selections live separately from agent
+   suggestions. A new proposal cannot revive a dismissed action or replace a
+   user-edited draft. Context reads expose those decisions to Codex.
+5. Emit a browser update only after commit. On reconnect, fetch a snapshot;
+   notifications are not the source of truth. A failed publication leaves the
+   previous brief intact.
+
+Return `{runId, revision, receivedAt}` as the receipt. Keep deduplication receipts
+for the MVP's lifetime; any future pruning must define a retry horizon first.
+Retry transient transport failures with the exact payload and key. Conflicts
+require a fresh context read and reconciliation, not blind retry.
+
+Use a small stable error envelope such as
+`{code, message, details, requestId}`: `400` malformed JSON, `401` invalid agent
+credential, `403` forbidden operation, `409` conflicts, `413` oversized payload,
+`422` invalid result structure, `429` throttling, and `5xx` transient server faults.
+No partial successes. This is a new machine API; it need not refactor unrelated
+existing UI error contracts.
+
+## Returning user intent to Codex
+
+The app must also expose what the user did. Otherwise the next scheduled run
+cannot distinguish a stale suggestion from a deliberate dismissal or correction.
+
+`POST /api/agent-requests` accepts a stable client `requestId`, a kind such as
+`refresh`, `reply-draft`, or `crm-edit`, an optional entity ID/source revision,
+and the user's text or requested edit. Persist before acknowledging. Repeated
+IDs with identical bodies return the same request; mismatches return `409`.
+
+A result links each completed request using
+`completedRequests: [{requestId, sourceRefIds}]`. All source references must exist
+in the publication; a `crm-edit` completion requires a life reference with the
+resulting content hash. Reject completion of unknown or already cancelled
+requests. This validates the claimed provenance link, not the file contents
+independently.
+
+A person-note edit appears as pending while external Codex applies it to life.
+It becomes confirmed only after publication references that request and supplies
+the resulting source revision. Failures keep the previous confirmed projection
+and the pending request visible. Do not label an app-only edit as already saved
+to life. Single-worker execution avoids requiring a job lease API for this MVP.
+
+life changes and app publication are not one transaction. If the process stops
+between them, the next run re-reads life and checks the request's outcome before
+applying it again. Prefer desired-state edits over blind append operations and
+preserve request provenance where the life workflow permits it.
+
+Actual message sending remains a separate, revision-bound user command. Publishing
+a draft or marking an agent request complete cannot send a message. Send results
+can be exposed in the next agent context for Codex to update life.
+
+## First useful slice
+
+Implement context read and result publish, persist them, and render a published
+brief plus a mixed activity list: weight entry, a simple optional task, routine
+steps and a reply linked to published life context. Prove duplicate replay,
+conflict handling, reload persistence and preservation
+of user decisions with fixture data. Then run one external Codex job manually
+before installing a timer. Add the request inbox when introducing on-demand
+generation or CRM editing. This order gives the agent somewhere to write before
+building automation around it.
+
+The [Beeper Copilot captures](references/beeper-copilot/README.md) provide the UI
+reference for those published results: conversation list, conversation body,
+person context, evidence chips, reply candidates and explicit review.
+
+## One activity list, different execution surfaces
+
+Home should unify what the user needs to do, while preserving the right controls
+for each activity. A shared task abstraction does not imply a universal checkbox
+or a universal chat card. Activity ordering, deferral and visibility are shared;
+execution and completion are domain-specific.
+
+| Activity kind | Inline or expanded Home UI                                            | Completion evidence                                         |
+| ------------- | --------------------------------------------------------------------- | ----------------------------------------------------------- |
+| `task`        | Concise title, optional detail, completion control                    | User marks it complete                                      |
+| `measurement` | Weight number field, unit, last recorded value/time, Save             | A measurement record is saved                               |
+| `reply`       | Person, latest relevant message, reason to reply, draft editor/review | Send is confirmed; a larger exchange may remain waiting     |
+| `routine`     | Ordered child activities and progress                                 | Required children complete, or an explicit skip is recorded |
+
+Use common fields such as `id`, `title`, `kind`, `evidenceIds`, `personId`,
+`parentId`, `occurrenceKey`, and optional recommendation/order metadata. User
+state (available, in progress, waiting, deferred, completed or skipped) is stored
+separately from Codex's recommendation. Each kind has a validated payload and a
+fixed application renderer; do not accept agent-generated executable UI or HTML.
+
+`routine` and `optional` in the current Home sections are grouping/priority
+choices, not exclusive UI types. A weight activity can be a morning routine step;
+a reply can be optional today. A routine groups child activities rather than
+duplicating their records. Home and Messages refer to the same reply activity ID,
+so editing or finishing it in either surface is immediately consistent.
+
+For example, an illustrative measurement activity published by Codex:
+
+```json
+{
+  "id": "weight-2026-09-29",
+  "kind": "measurement",
+  "title": "Log weight",
+  "parentId": "morning-2026-09-29",
+  "occurrenceKey": "2026-09-29@Asia/Tokyo",
+  "payload": { "metric": "weight", "unit": "kg" },
+  "evidenceIds": []
+}
+```
+
+Codex chooses or recommends the activity; the user supplies the measured number.
+The app saves the observation and its occurrence time without invoking inference.
+Corrections preserve the observation history. Completion must reflect that save,
+not merely a checked box. The agent can read this execution evidence on its next
+run and maintain life accordingly; the app does not need to infer health advice.
+
+Recurring activities need stable per-occurrence IDs: publishing tomorrow's
+routine must not reopen today's completed one. Missing time slots are valid;
+the user explicitly wants flexible daily ordering rather than a strict calendar.
+A real appointment can still retain its explicit date/time.
+
+Reply completion follows the confirmed send state, not draft generation, review
+or merely pressing Send. A conversation can contain multiple distinct commitments;
+Codex determines those relationships from sources. The application stores explicit
+links and user choices without deciding that one reply resolves every commitment.
+
+The resulting Home can place a weight input, a routine's next step, a reply
+preview and a simple task together. Use a compact shared outer row and expand
+the relevant controls in place; detailed conversation/CRM views remain available.
+Natural-language entry creates an external-agent request, while direct numeric
+entry, checkboxes and draft edits remain immediate deterministic UI operations.
+
+## Routine execution and workstyle learning
+
+The user wants to import ideal routines from life, track their execution in this
+app, and use external Codex analysis to develop a workable personal workstyle.
+This adds explicit execution analytics to the earlier reference-only routine
+concept; it does not imply that all ideals are already practiced or due daily.
+
+Keep three levels distinct:
+
+1. **Routine definition:** life source, stable ID, definition revision, purpose,
+   trigger, steps, and completion rule. Codex publishes a structured projection.
+2. **Trial/activation:** which version is currently being tried, applicable days
+   or situations, and the chosen scope. Importing an ideal into the catalog does
+   not silently activate every step as a daily obligation.
+3. **Occurrence and observations:** the actual applicable occasion, its frozen
+   definition revision, user actions, recorded values, skips, and corrections.
+   The application is the source for execution history; life links to it rather
+   than maintaining a second completion ledger.
+
+An approved routine definition can be instantiated deterministically by the app
+on its recurrence or a user action such as starting/ending work. Codex need not
+run every time a routine appears. Situational occurrences should come from an
+explicit trigger or confirmed source, not an assumed event inferred by the UI.
+Keep occurrence identity stable across delayed cron runs and retries. Do not
+turn unfinished instances into an ever-growing daily backlog automatically.
+
+Proposed operating loop:
+
+- **Import:** Codex reads life and publishes a routine catalog with sources and
+  revisions. Show what is already active and what remains an ideal/candidate.
+- **Try:** choose a small set and a review window, for example one or two weeks.
+  These durations and counts are starting suggestions, not fixed app rules.
+- **Execute:** Home presents due/applicable occurrences with kind-specific UI.
+  Save completion evidence as part of the natural action: entering a value,
+  sending a reply, writing a resumption note, or completing a task. Optional
+  friction feedback can be one tap; reporting a reason is not required.
+- **Review:** the application calculates counts from recorded events. External
+  Codex reads the counts and underlying evidence, relates them to life context,
+  and publishes a short review with observations, uncertainties and proposals.
+- **Adjust:** the user adopts, modifies or rejects a proposal. Codex updates the
+  ideal/working procedure in life and publishes a new definition revision.
+  Historical occurrences retain their previous revision and completion rule.
+
+A scheduled daily job can refresh the overview, while a weekly job reviews the
+experiment. Neither creates additional inference inside the app. The publishing
+contract will need versioned routine definitions and review artifacts alongside
+activities; context reads must expose execution observations and aggregate counts.
+Those are deterministic data contracts, not a new agent runtime.
+
+### Metrics that preserve meaning
+
+Show counts and denominators next to percentages. For each routine revision and
+review window, report completed, partially completed, explicitly skipped,
+deferred, not applicable, and unrecorded occurrences separately. A past due item
+without an observation remains unrecorded, not verified non-execution.
+
+A useful default is **recorded attainment = completed / applicable planned
+occurrences**, accompanied by observation coverage. For example, 5 completed,
+1 explicitly skipped and 1 unrecorded out of 7 applicable occasions yields 5/7
+recorded attainment and 6/7 observed outcomes. It does not prove that the person
+failed to act on the unrecorded occasion. If a resolved-outcome rate is also
+shown, label its different denominator explicitly. Keep skipped occasions in
+the planned denominator; exclude not-applicable ones with a recorded reason and
+retain plan revisions so exclusions cannot silently rewrite prior performance.
+
+Do not count a routine parent and every child as independent equivalent successes
+in a global percentage. Analyze routines and steps at separate levels. Optional
+ideas that were never scheduled/adopted do not belong in the planned denominator.
+Explicitly record reduced/partial completion without silently calling it full
+completion. Measurement adherence is about saving a measurement, not moving the
+number in a preferred direction; reply counts do not measure relationship quality.
+
+Attainment alone cannot establish usefulness. Add lightweight, optional feedback
+on effort and whether a routine helped, plus domain-specific evidence such as a
+resumption note being available next time. Compare versions over named periods
+and show sample sizes. Codex can suggest one change to try next, but sparse
+observations or coincident changes do not establish a causal improvement.
+
+The review should answer: what was practical, where execution stopped, what was
+useful, and what small change is worth trying next. Good outcomes can include
+shortening, reducing frequency, changing the trigger, or retiring a routine.
+Do not optimize a single global completion score at the expense of the purpose
+of the work or the user's freedom to change the plan.

+# Beeper integration research
+
+Researched 2026-09-28. Proposal only; no integration was installed during research.
+
+## Current direction
+
+External Codex performs inference, reads Beeper, and reads/writes life under
+Rensheng conventions. life is the CRM source of truth, serving the role Scrapbox
+plays in Beeper Copilot. This application accepts structured publications and
+provides the UI, persistent execution state, and user feedback. It does not need
+a new CRM inference runtime or life filesystem editing engine.
+
+Home combines routines, optional tasks, measurements and communication as
+activities, with different controls for each kind. A weight entry, reply editor,
+routine checklist and simple completion control belong in one daily overview.
+
+See [external agent publishing](agent-publishing-design.md) for the concrete
+contract and gbrain cron findings, and the
+[Beeper Copilot screenshot gallery](references/beeper-copilot/README.md) for UI
+references. This supersedes earlier proposals for app-managed inference and
+direct app-to-life editing.

+Existing CLI authentication can be reused with bounded, fixed-argument
+`api get` calls and `watch --target um790 --read-only --json`. Do not expose
+arbitrary CLI/RPC command strings as agent tools. The
+[official TypeScript SDK](https://github.com/beeper/desktop-api-js) is an alternative
+after explicitly provisioning an application credential. Choose one transport
+inside the adapter; automatic CLI/SDK fallback is unnecessary.
+
+The [MCP guide](https://developers.beeper.com/desktop-api/mcp/) uses Streamable
+HTTP. The [changelog](https://developers.beeper.com/desktop-api/changelog/) removes
+the old Beeper MCP SSE transport; our own browser SSE can remain.
+
+## Synchronization findings
+
+The running server's `/v1/spec` explicitly states that WebSocket delivery is
+at-most-once, has no replay after reconnect, and uses per-connection sequence
+numbers. The [WebSocket guide](https://developers.beeper.com/desktop-api/websocket-experimental/)
+also describes experimental status and best-effort payloads. HTTP reconciliation
+is required after disconnects and periodically. Do not start Codex per message.
+
+Subscribe before initial reconciliation, track changed chats during it, then
+refetch those chats. Commit progress only after persistence. Use canonical
+target/account/chat/message IDs and revisions or content hashes. Edited/deleted
+evidence invalidates affected drafts. One missing list result does not prove
+deletion. CLI watch webhooks are best-effort and can drop on queue overflow;
+a same-machine worker avoids needing a webhook receiver, not the need to reconcile.
+
+The [message API](https://developers.beeper.com/desktop-api-reference/resources/messages/methods/list/)
+returns opaque cursors. life's backfill guide records missed/duplicated pages
+when CLI message IDs were used as cursors, plus API order differing from timestamp
+order. Do not stop pagination merely because a date boundary was crossed.
+
+## Reference findings
+
+### life
+
+`life/briefs/2026-09-25-executive-support-design.md` describes source-backed reply
+assistance, explicit review and durable personal context. Existing
+`life/docs/beeper-backfill.md` and `life/scripts/beeper_backfill.py` implement
+reviewed, resumable CLI backfill on this machine.
+
+That helper is not a continuous inbox worker: discovery covers 100 recent chats,
+pages require review/acknowledgment, and some quotes, forwarded messages and
+attachments are deliberately excluded. Its output is not a complete conversation
+view. Reuse its identity/provenance rules. Its guide warns that CLI 0.6.2 raw
+`status --json` can expose credentials.
+
+Codex should maintain existing life domain pages. The app displays published
+CRM projections; user corrections return as durable requests to Codex. It must
+distinguish pending corrections from confirmed life changes.

+# gbrain open loops and personal execution support
+
+Research, 2026-09-28. Source inspection at gbrain revision
+`e78f1c38b947b053f3a46881340f74f316be855a`; upstream tests were read, not executed.
+Application behavior below is proposed, not implemented. This supplements
+[external Codex publishing](agent-publishing-design.md).
+
+## What gbrain implements
+
+### Scope: ingestion is broader than the open-loop engine
+
+gbrain as a whole is not Gmail-only. Its implemented ingestion paths include:
+
+- Google: Gmail, Calendar and Contacts.
+- GitHub: issues, pull requests, comments, reviews and associated metadata.
+- ChatGPT and Claude account history through live session-cookie connectors.
+- Imported agent transcripts, including Codex, Claude Code, OpenClaw and Hermes,
+  plus consumer conversation exports.
+- Markdown repositories and files, inbox-folder capture, CLI/MCP page writes,
+  and the HTTP ingest endpoint.
+
+See [data ingestion](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/docs/guides/data-ingestion.md),
+[GitHub source](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/docs/guides/github-source.md),
+and the [live connector registry](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/connectors/registry.ts).
+
+Custom ingestion extensions and agent-side service access are separate from
+native synchronization. Documentation mentions Slack, iMessage and other
+messaging services through external agent gateways; this does not establish
+built-in history sync or open-loop detection for each service. No native Beeper
+source was identified. The automatic open-loop detection path inspected below
+is specifically wired to Google email threads, not every ingested page.
+
+### Detection
+
+Collection itself is implemented code, not an LLM asked to copy every item.
+`gbrain sync --source <id>` dispatches to native Google/GitHub synchronization;
+`gbrain connectors sync chatgpt` fetches conversation history and passes it to
+the transcript importer. Agents can invoke these commands, but a scheduler can
+invoke them directly without an interactive agent. Semantic extraction and
+optional embeddings are separate model-using stages.
+
+The [email recipe](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/recipes/email-to-brain.md)
+explicitly says that earlier versions asked agents to build a collector script,
+while current versions ship that logic in the native connector. The illustrative
+`scripts/email-collector/email-collector.mjs` path in the deterministic-collectors
+guide is not a shipped script at this revision. Agent-authored memory and custom
+external integrations remain distinct ingestion paths; not every integration
+mentioned in a recipe is a built-in connector.
+
+The engine operates on Google/Gmail threads. It is not a ready-made Beeper
+integration. It distinguishes five kinds of unfinished interaction:
+
+| Kind                  | Detection                                                                                                            |
+| --------------------- | -------------------------------------------------------------------------------------------------------------------- |
+| Unanswered inbound    | Last substantive message is from someone else, owner is in To, at least 24 hours old                                 |
+| Unanswered outbound   | Last substantive message is from owner, external To recipient exists, body contains ASCII `?`, at least 72 hours old |
+| Commitment owed by me | LLM extracts an unresolved promise by the owner                                                                      |
+| Commitment owed to me | LLM extracts an unresolved promise by someone else                                                                   |
+| Decision pending      | LLM extracts an explicit unresolved choice or question                                                               |
+
+The [detector](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/google/loop-detect.ts)
+filters machine senders, calendar system messages, self-only threads, muted
+senders/threads, and inbound list mail or CC-only delivery. Outbound attribution
+uses the first external To recipient. Evidence includes the last message ID and
+up to 200 characters of its body.
+
+These rules are useful candidate detection, not proof that a response is owed.
+Inbound messages need not contain a request. Outbound requests without `?`,
+including full-width Japanese `？`, can be missed. In group chat, a third party's
+message is not evidence that the intended recipient answered.
+
+The [LLM extractor](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/google/loops-extract.ts)
+processes eligible threads whose newest message is within 30 days. It sends the
+newest 12,000 characters, requesting structured direction, counterparty, promise,
+due date and quotation. Spam/trash and machine-only conversations are excluded;
+owner participation can override bulk-mail exclusions. Updates remain eligible
+because they may contain invoices or contracts.
+
+Important implementation limits:
+
+- A malformed item rejects the whole parsed response before writes. This does
+  not make the subsequent facts, loops and graph writes one atomic transaction.
+- A quotation is checked against the supplied text after whitespace
+  normalization. A mismatch removes the quotation **but retains the loop**.
+- Commitment confidence is a fixed `0.85`; decision confidence is `0.8`.
+  Neither is a calibrated probability or a model-generated confidence estimate.
+- LLM evidence references a page; it does not require a specific message ID.
+- Date-only deadlines are stored at `23:59:59Z`, not the user's local end of day.
+- Deduplication hashes thread, direction and generated text. A paraphrase can
+  produce a second loop for the same real-world promise.
+
+## Resolution and persistence
+
+The [store](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/loops/loops-store.ts)
+keeps `open`, `done`, `dropped` and `stale`, with closure history.
+
+- A change in whose turn it is automatically closes the appropriate
+  deterministic unanswered loop. Muting or a same-side reminder does not.
+- Reply-driven closure applies only to `deterministic_thread` loops.
+- LLM extraction upserts candidates. It does **not** reconcile previously
+  stored promises that disappear from a later extraction. Asking the model to
+  omit fulfilled promises is insufficient to close those records.
+- Users can mark a loop done or dropped. Reprocessing the same observed activity
+  does not resurrect it; genuinely newer activity can reopen it.
+- LLM loops become stale after a deadline is over 14 days past **and** activity
+  is over 14 days old, or after 90 days without activity. Stale is not fulfilled.
+- Dedicated snooze/defer operations are absent. Mutes prevent future detection;
+  they do not close existing loops.
+
+For example, “I will send the document Friday” and “Thanks!” can settle the
+reply exchange while leaving the document promise open. Completion needs its
+own evidence or the user's decision.
+
+## Scheduling, freshness and ranking
+
+The detector runs when
+[Google source processing](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/google/google-source.ts)
+loads a thread. Delta sync processes threads changed in Gmail history. No
+dedicated elapsed-time reevaluation was found in that path: a thread skipped
+inside the grace period may not be reconsidered merely because 24/72 hours pass,
+until a full sync or another touch. This is a code-based inference, not a
+reproduced runtime failure.
+
+Extraction jobs use source, page slug and newest-message timestamp as their key.
+Pending work has a 500-job ceiling per source. Overflow is logged, but a durable
+backlog of excluded candidates is not maintained; another thread change may be
+needed to enqueue them. Successful source sync therefore does not imply complete
+or current inference results.
+
+The [waiting operations](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/core/ops/loops.ts)
+group loops by person, defaulting to three groups. Ranking combines loop count,
+deadline proximity, age and backlinks to the person's page. It is not a
+personal-capacity or action-readiness model. Retrieval considers up to 500
+recent loops before ranking and reports truncation.
+
+The [CLI](https://github.com/garrytan/gbrain/blob/e78f1c38b947b053f3a46881340f74f316be855a/src/commands/loops.ts)
+normally refuses a waiting report if all Google sources are over 24 hours stale.
+One fresh source permits display, so per-source freshness still matters. Remote
+operations omit quotations, deep links and entity context that trusted-local
+calls may expose.
+
+## Proposed application flow
+
+Keep life as CRM truth and external Codex as the reasoning and filesystem writer.
+The app accepts structured proposals and records user decisions and execution.
+
+1. Beeper supplies conversation events. External scheduled Codex runs also
+   reconsider items whose review time has arrived, even without a new message.
+2. Codex distinguishes a request, an accepted promise, an unanswered exchange
+   and a decision. A request must not automatically become an accepted obligation.
+3. Publish candidates with stable identities, source message references,
+   observations, direction, counterparty and any real deadline. Avoid using
+   generated prose as the only identity.
+4. Home selects a small set of actionable activities alongside routines and
+   measurements. Open loops are candidate context, not automatically today's list.
+5. Replies open conversation and draft review; document promises open the actual
+   next action. Weight entries and routines retain their own execution controls.
+6. Keep waiting items available outside the active list. A review date can bring
+   a follow-up back without pretending the other person's work is the user's task.
+7. Record done, not needed, defer and corrections separately. Codex consumes
+   these decisions and maintains life. New messages alone should not override
+   an explicit rejection of the same obligation.
+
+Track source observation and inference completion separately. An old successful
+report can remain visible with its timestamp; incomplete coverage must not be
+presented as certainty that nothing remains. Old promises should enter review,
+not silently count as resolved.
+
+## ADHD-oriented design hypothesis
+
+The intended benefit is to externalize remembering, choosing, starting and
+resuming work. These are product hypotheses for personal use, not evidence that
+this application treats ADHD or that all people with ADHD need the same UI.
+
+[NICE guidance](https://www.nice.org.uk/guidance/ng87/chapter/recommendations)
+describes individually chosen environmental modifications, reducing distraction,
+shorter periods of focus with breaks, and written support for verbal requests.
+[NIMH guidance](https://www.nimh.nih.gov/health/publications/attention-deficit-hyperactivity-disorder-what-you-need-to-know)
+includes routines, written reminders and breaking large tasks into manageable
+steps. These support the general direction, not a specific dashboard layout.
+
+Design hypotheses to evaluate:
+
+- Show a few concrete next actions with the material needed to start. Three is
+  a possible initial display limit, not a clinically established number.
+- Store the broader context out of the user's working memory while keeping it
+  retrievable. Do not turn every detected message into another decision to triage.
+- Support restarting after an interruption: what was last done, what remains,
+  and a small next step. A missed day must not require clearing a wall of debt.
+- Keep flexible routines while preserving genuine external deadlines. Hiding
+  real deadlines is different from avoiding a rigid minute-by-minute schedule.
+- Let ordinary actions use direct controls; natural language is an additional
+  route, not a requirement to formulate a prompt before every action.
+- Use restrained reminders and easy correction. False positives and repeated
+  resurfacing are additional work, even when recall improves.
+- Review routine fit and effort as well as completion. Useful questions include
+  whether important promises were missed, whether suggestions were wrong, and
+  whether the app made starting or resuming easier. Avoid optimizing a completion
+  percentage at the cost of meaningful work or rest.
+
+An initial trial can combine one routine, one genuine promise and one waiting
+item, then review the actual friction before expanding automatic capture.

+## Finding
+
+There is substantial overlap. Memory, CRM, daily briefs, natural-language task
+management and agent tools are not unique to this workspace. Its remaining
+product hypothesis is a low-friction daily execution interface: turn personal
+context into a few actionable choices, execute through appropriate controls,
+retain actual outcomes, and improve routines from experience.
+
+This hypothesis has not been demonstrated by the current mock. Home, Messages
+and Journal still use in-memory prototype state; Beeper sending and life
+integration are not connected. Research has real persisted decks and Codex chat.
+See [current status](../README.md) and [execution prototype](execution-support.md).

+portable, sourced memory across agents. Rensheng's useful distinction here is
+the deliberately small, directly readable context model and its operational
+conventions. It does not ship a replacement for gbrain's complete ingestion and
+retrieval infrastructure. See [Rensheng's comparison](https://github.com/yutakobayashidev/rensheng/blob/c06c4e3f290800752a0c252c84fbca0eed61e45d/COMPARISON.md).
+
+## The nearer overlap: OpenBrief
+
+The Rensheng repository also contains an implemented
+[OpenBrief](https://github.com/yutakobayashidev/rensheng/blob/c06c4e3f290800752a0c252c84fbca0eed61e45d/docs/openbrief.md)
+daemon, desktop app and mobile companion. It handles observations, bounded
+briefs, agent proposals, confirmed decisions and return anchors. Thus resumption
+support should not be described as absent from the existing Rensheng repository.
+
+Before integrating that feature, choose one owner for its decisions and return
+anchors. If OpenBrief remains active, this workspace should reference its
+records rather than independently maintain conflicting copies. Reusing its
+runtime is not automatically required: its ACP ownership and desktop collection
+solve a narrower problem than this app's external-Codex publishing contract.
+Actual compatibility needs a separate implementation check.
+
+## Recommended division
+
+- **Original systems:** messages, calendar events and source evidence.
+- **life:** relationship context, explicit preferences, accepted goals and routine
+  definitions. External Codex maintains these files. Compiled claims remain
+  traceable to original evidence and user corrections.
+- **External Codex:** interpretation, candidate selection, reply drafts and
+  periodic review. No new app-owned reasoning engine is required.
+- **Workspace:** published suggestions, user choices, activity occurrences,
+  measurements and execution events, plus the controls to act on them.
+- **gbrain, optional:** collection or retrieval infrastructure if a measured
+  source-coverage or search problem justifies operating it. Do not introduce a
+  second authoritative profile, task list and routine definition by default.
+
+Durable context and execution events have different owners. Copy meaningful
+outcomes into life through Codex; do not continuously reconcile two independently
+editable task databases. If gbrain indexes life later, treat the indexed copy as
+a projection and first verify its source-write behavior. This is an integration
+proposal, not a tested read-only mode or a promise that whole-brain deployment
+can be reduced to a dependency-free collector.
+
+## Options and decision criteria
+
+1. **Rensheng + Codex + existing apps:** lowest custom application upkeep. Prefer
+   this if a daily brief and source links already lead to action reliably.
+2. **Rensheng + this workspace + Codex:** recommended experiment for the stated
+   need for routines, measurements and communication in one daily view. The
+   execution interface and recorded outcomes must earn their maintenance cost.
+3. **Add gbrain underneath:** consider when collection, retrieval or cross-agent
+   memory becomes an observed bottleneck. Its connectors do not supply a native
+   Beeper integration or automatically replace external-Codex reasoning.
+4. **gbrain + existing chat/source apps:** reasonable if generic memory, Gmail
+   waiting reports and conversational task management satisfy the actual need.
+   In that case, much of this workspace need not be built.
+
+## Smallest useful experiment
+
+Run a suggested one-to-two-week trial with one real life routine, one measurement
+and a small set of real Beeper follow-ups. This duration is a practical starting
+point, not a clinical protocol. Persist records before adding more mock screens.
+
+Publish a short brief and actionable items through the proposed
+[Codex interface](agent-publishing-design.md). Support direct execution, deferral
+and correction. Keep reply completion distinct from fulfillment of a promise.
+Retain events across reloads. Use observed results in one Codex-led review and
+save only adopted routine changes to life.
+
+Compare with the simpler baseline: Codex writes a daily brief to life and the
+user acts through existing apps. Assess actual usefulness: easier starts and
+returns, important commitments missed, false positives, correction effort,
+and whether the workspace is opened without prompting. Completion rate can
+support review but must preserve planned denominators, missing coverage and
+routine-version changes. No specific UI is claimed to treat ADHD.
+
+If the interface does not reduce friction, simplify to the baseline rather than
+defend the project through feature count. Defer generic vector search, knowledge
+graphs, a new agent framework, broad connector coverage and additional dashboard
+expansion until this execution loop proves useful.

+
+## Patterns to reuse
+
+- Three coordinated panes: compact list, a dominant conversation, and persistent
+  person context. In this app the right pane should show Codex-published life
+  context, source references and pending user corrections.
+- Compact network badges on identities and messages. Keep original conversation
+  identity available even when presenting a person across networks.
+- A reply review sits near the conversation and composer. Candidate selection,
+  editing and confirmation remain visible steps; approval is distinct from
+  generating or inserting a suggestion.
+- Evidence chips next to contextual statements provide a path back to messages
+  or the published life source reference.
+- Suggested actions include their reason and can populate the appropriate
+  editor. The app can render externally produced suggestions without inference.
+
+The LP's dense right panel and desktop three-pane arrangement are useful
+references. Its mobile demo squeezes the columns and is not a good mobile
+navigation model for this app: use list → conversation with an accessible context
+panel instead. The LP's relationship-phase labels, coverage scores and confidence
+percentages are demo product choices, not requirements for this personal CRM.
+
+For Home, borrow the contextual presentation inside a reply activity rather than
+embedding the full inbox. Weight logging needs a numeric input; a routine needs
+steps; an optional task needs a simple completion control. These can coexist in
+one activity list without forcing every activity into a chat layout.
+
+See [external agent publishing](../../agent-publishing-design.md) for the proposed
+producer/consumer boundary and typed activity contract.
