 - Tools: [`src/tools/`](src/tools/). `retrieve_data` runs catalog-backed QueryIR; `analyze_*` tools consume table outputs; `render_chart` makes deterministic Plotly JSON.
 - Query layer: [`src/query/`](src/query/). Defense stack: catalog/IR validation, compiler whitelist, sqlglot SELECT-only guard, read-only DB session, timeout, row limit.
 - Analysis catalog is Go-materialized and read through [`src/catalog/`](src/catalog/); missing analysis scope fails open to user scope.
+- **Conversation scope (2026-10-29)** — [`src/agents/scope/`](src/agents/scope/). Scope = the values of categorical columns an answer covers (a site code, a section, a unit); periods are not scope. **Code owns it; the planner only declares "all X"** (`TaskList.scope_change`) — gate runs showed the planner failing more the more scope it was asked to handle. Code: reads the full value lists of small non-PII string columns once per analysis ([`values.py`](src/agents/scope/values.py), read-only GROUP BYs through the query pipeline, cached; loads alongside the planner call); pins the **focus** from the objective against those lists; matches the user's own words against the focus columns' lists; carries a previous value into a follow-up only when the router's rewrite restates it ("go home" for complete questions — Rifqi 2026-10-29); then, inside the planner's retry loop **before validation** (`PlannerService.plan(prepare=…)`, `SlowPathCoordinator._scope_hook`), fills missing filters, keeps planner filters grounded in the user's words or the rewrite, replaces invented ones, respects a subset-vs-total structure on one table, moves a value to the column whose list holds it, strips typed ids / made-up placeholders on FK id columns, and joins a code column through exactly one FK ([`engine.py`](src/agents/scope/engine.py)). A scope line built from the values that ran is appended under every data answer; the `TurnScope` is persisted on `AnalysisRecord.scope` (`report_inputs`, Python-owned JSONB) and read back next turn (`PostgresReportInputStore.latest_scope`). The report anchors scope on the focus: answers outside it are labelled comparisons, never pooled. Why: on 42 real turns the objective's site default was applied 7/27 times and 4 answers named a scope their query never filtered. "Every X" is read from the user's words (a quantifier before a column word: "semua site", "per section") or a breakdown on the column (also via its FK id), and drops planner filters nobody asked for; a comparison the queries cover only partly ("SDJ dibanding IPR", one side fetched) is widened to every typed value; negations ("selain SDJ"), a named unit (lifts the focus for the turn) and unknown codes ("not found", never swapped) are handled; the line marks partly-applied columns. Gate (2026-10-30): 21/23 + 8/8 live, 0 refusals, identical reruns; planner eval ctx/site subset 7/7. Known limit: the planner can still mis-shape a comparison's analysis step (an A/B step naming a site as a section) — needs a planner example.

+here, because text the planner "should" apply was applied on 7 of 27 turns:
+
+- `resolve_scope` merges pinned focus / previous scope / this turn's change into
+  the effective scope. A value is only accepted when the user actually typed it
+  (`grounded`) — the planner may misread a message, it may not invent a code.
+- `apply_scope_to_plan` injects the effective scope into every `retrieve_data`
+  IR, adding the lookup join when exactly one foreign key reaches the column.
+- `render_scope_line` describes what RAN (the executed filters in each output's
+  meta), not what was intended, so the line can never name a scope its query
+  never filtered.
+
+Pure and never-throw (house rule: these sit on the answer path). Generic: an

+here knows what a site or a section is. Integer columns (year/month/week) are

+- the planner only declares "every value of this column" (`ScopeChange`);
+- code applies it to every `retrieve_data` IR before validation, renders the line
+  the user sees, and persists a `TurnScope` on the turn's `AnalysisRecord`.
+
+Generic on purpose: an entry is any categorical catalog column by NAME plus its
+values. Nothing here knows what a "site" or "section" is. The period is not part of
+scope — the planner keeps resolving periods (a forecast or a year-over-year question
