feat(signals): add self-driving feature reports - #68160

Conversation
Adds a "Plans" tab to the inbox where users plan features interactively with a cloud agent, then hand ongoing ownership to a per-plan scout. Backend (products/signals/backend/plan_mode/): - InboxPlan viewset: list (Postgres planning-marker based, drafts first), create, finish, start_implementation endpoints - create_plan: report + groundskeeping note + interactive planning task whose first message bootstraps the agent (instructions ride in pending_user_message since interactive runs get no system prompt) - finish_plan: safety/actionability defaults, convergent owner scout creation under the deterministic signals-scout-plan-<id> name, and auto-start of the first implementation pass - start_implementation_for_report: single guarded code path shared by finish, the owner scout tool, and the manual UI button; refuses while a pass is in flight Scout harness: - new signals-scout-start-implementation tool on the internal signal_scout_report:write scope (sandbox-only, allowed_tools gated) - owner scout body is platform-authored and converged at finish; plan-specific tailoring lives in an "Owner scout playbook" note - scouts perform all applicable actions per activation, including a signal sweep that soft-links related reports via the new associated_report artefact type Artefacts/model: - new question artefact type (task-attributed = agent asks user, user-attributed = feedback for agents) and associated_report type - reports enforce an 8000-token embeddability cap on title+summary (shared cached tiktoken encoder; API paths 400, model save truncates) Frontend (inbox): - Plans tab with draft visibility, new-plan modal, and a plan detail view with status/owner/feed sub-tabs - draft view embeds the live planning conversation (TaskRunChat) beside a polled read-only overview, with a finish-plan button that surfaces missing requirements - open questions and outstanding feedback sections, click-to-edit title/summary/notes, owner scout embedded via ScoutDetailView, "Start implementing" fallback button, collapsible code references Tasks: pr_loop_enabled now requires create_pr, so no-PR runs (planning conversations) skip the CI follow-up loop.

finish_plan does not write a priority judgment. It writes only SafetyJudgment and ActionabilityAssessment; priority (PRIORITY_JUDGMENT) is a pre-requirement checked in plan_readiness that the agent must have already set during planning. An API consumer reading this could incorrectly believe they can skip setting priority before calling /finish.

The membership filter uses content__contains='"product":"signals"' — a raw substring check that silently breaks if the serialiser ever emits spaces (e.g. "product": "signals" from standard json.dumps). If that changes, all plan list tabs return empty with no error. The current path uses compact Pydantic output, so it works today, but the correctness is load-bearing on a serialisation detail. Consider adding a dedicated is_planning_marker boolean column (or a separate lightweight join table) to make membership an explicit, indexed first-class concept rather than a JSON-substring scan.

There was a problem hiding this comment.
title alone exhausts the entire 8 000-token budget, budget becomes 0 or negative and summary_tokens[:max(budget, 0)] is an empty slice. encoding.decode([]) returns "", so the backstop silently replaces the summary with an empty string. plan_readiness then flags the summary as missing, permanently blocking finish_plan on that report. Even keeping a few tokens is better than producing an empty summary.

_resolve_from_payload returns DEFAULT_RUNTIME for both an absent block and a matched block that parses to all None. Line 169 forces Claude Opus 5 in both cases. This prevents an explicit feature-discovery block from selecting the agent-server default.

Resolve every detail report through feature_reports_queryset.
The detail actions only check team ownership and deletion status. The services do not enforce feature membership: planning can start without membership, readiness treats a safety judgment as completed planning, and implementation checks readiness, access, repository, and in-flight state only. A non-member report with the required artefacts can therefore enter the feature lifecycle and start implementation. Use feature_reports_queryset(self.team.id) for every detail lookup.

Enforce the combined token cap when the summary is empty.
SignalReport.save() calls truncate_summary_to_embeddable() only when self.summary is truthy. An oversized title with an empty summary therefore persists unchanged. If truncation reduces a non-empty summary to empty, the oversized title also remains. render_report_document() then sends the title to the report embedding worker, which can reject it for exceeding the embedding limit.
The edit serializer checks only the submitted summary, and the report-generation schema rejects blank fields but does not enforce the combined cap. Apply the cap to both title and summary on every content write. Do not gate enforcement on self.summary.

Validate the effective title and summary before saving.
SignalReportContentUpdateSerializer.validate_summary checks only the incoming summary. Because both fields are optional, a title-only update can also change the combined token count. SignalReport.save() then truncates the summary when the combined title and summary exceed MAX_EMBEDDABLE_REPORT_TOKENS, so the API accepts input but persists different content.
Compute the effective title and summary for this report before saving and reject the update when their combined token count exceeds the limit. Keep the model-level truncation as a backstop for non-API writers.

Treat prompt echoes as turn boundaries. When ProcessTaskWorkflow dispatches a queued steering follow-up while an earlier follow-up remains active, both prompt echoes can enter the same original_skip_lines slice. _check_logs skips them at lines 847-848, so its reverse walk joins agent text from both responses into last_message. MultiTurnSession._parse_and_validate can then select the wrong JSON object or fail on malformed fragments. Keep prompt echoes decisive and skip only usage_update and session_info_update.

lines 847 - 848, Update the update-filtering condition in _check_logs to skip
only usage_update and session_info_update; remove _PROMPT_ECHO_UPDATES from this
skip set so prompt echoes remain decisive turn boundaries during reverse log
processing.

Warning
This work is an intentionally paused draft. It is not ready to merge or enable broadly.
The handoff document records the goals, current architecture, safe restart steps, and remaining decisions.
Outstanding before merge:
Problem
Users need a durable feature record that connects repository discovery, planning conversations, implementation, and ongoing monitoring.
Reactive inbox reports do not provide that long-lived ownership flow.
Changes
Migrations and regenerated API/MCP clients are mechanical contract updates. The execution, retry, and ownership boundaries require substantive review.

🤖 Agent context
Autonomy: Human-driven (agent-assisted).
Claude Code and Codex assisted the implementation and handoff. GitHub CLI, Git, shell tools, and focused tests supported this checkpoint.
The design evolved from plan mode into durable feature ownership. Research remains sequential; per-feature worker isolation and concurrency are future evaluation items.
Handoff skills: /writing-pr-descriptions, /running-ci-preflight, /writing-code-comments.
Earlier implementation skills: /improving-drf-endpoints, /django-migrations, /adopting-generated-api-types, /writing-tests, /implementing-mcp-tools, /writing-kea-logics, /debugging-local-task-agent-runs.
Local task diagnostics informed robustness changes. Response fixtures use synthetic message fragments; raw logs, credentials, and local audit notes are excluded from this PR.
