 - **NEVER index the bare `deleted_at` column - use a PARTIAL trash index `WHERE deleted_at IS NOT NULL`.** `ensure_soft_delete_columns` creates `idx_<table>_trash ON (deleted_at) WHERE deleted_at IS NOT NULL` (and drops any legacy full `idx_<table>_deleted`). A full `deleted_at` index is a planner hazard: the column is one giant `NULL` bucket plus many unique delete-timestamps, so `sqlite_stat1` mis-estimates `deleted_at IS NULL` as returning ~2 rows and the planner picks that index for live reads, then `USE TEMP B-TREE FOR ORDER BY` to sort the whole live set (the global feed was doing exactly this, with 82% of posts soft-deleted). The partial index serves the admin Trash view (`deleted_at IS NOT NULL`) cheaply and stops poisoning live `IS NULL` queries.
 
-- **For "live, newest-first" listings add a composite or live-partial index that includes the sort column.** A `WHERE deleted_at IS NULL ORDER BY created_at` query needs the ordering in the index or it filesorts. Posts use a partial `idx_posts_live_created ON (created_at) WHERE deleted_at IS NULL` (feed) plus `idx_posts_user_created (user_uid, created_at)` (profile); comments use `idx_comments_target_created (target_type, target_uid, created_at)`; votes use `idx_votes_user_target (user_uid, target_uid)` (the per-user "my_vote" check on every card); notifications/gists/projects use `(user_uid, created_at)`. All were verified to drop the `USE TEMP B-TREE FOR ORDER BY` step.

All were verified to drop the `USE TEMP B-TREE FOR ORDER BY` step.
 
 - **Index the non-`uid` lookup keys too, not just the sort/owner columns.** A demand-vs-supply audit added the last missing single-key lookups: the `resolve_by_slug` hot path filters `slug` on content detail pages, so posts/gists/news/projects each get `idx_<table>_slug (slug)`; `get_setting`/`set_setting` filter `key`, so `idx_site_settings_key (key)`; the container store's `find_one(slug=)`/`find_one(name=)` fallbacks get `idx_instances_slug`/`idx_instances_name`. The DM thread load `find(sender_uid=, receiver_uid=)` gets the covering composites `idx_messages_conversation (sender_uid, receiver_uid)` + `idx_messages_conversation_rev (receiver_uid, sender_uid)` (the read-flag `UPDATE` uses the reverse); the badge-has check gets `idx_badges_user_name (user_uid, badge_name)`; the admin user list `ORDER BY -created_at` gets `idx_users_created_at (created_at)` (the existing `(role, created_at)` cannot serve a full-table created_at sort). All are non-unique so `_index` always creates them even if legacy duplicate data exists. Column sets already resolved to ~1 row by an existing prefix index (votes `+target_type`, game_quests `+kind`, poll_options `position`) are intentionally left uncovered - a trailing column there only adds write cost.

The WS adds live bidirectional delivery, typing, read receipts, and in-process presence on top of the existing `messages` table; both the WS `send` and HTTP `POST /send` route through the shared `services/messaging/persist.py` `persist_message` choke point (identical audit/notification/mention) and then through `_finalize_and_broadcast`, which awaits any pending SYNC AI correction/modifier futures (DM content runs through both, so typing `@ai <instruction>` executes live) and broadcasts the FINAL corrected/modified content (the WS path passes `request=websocket` and awaits directly since HTTP middleware does not run for websockets; the frontend swaps the sender's optimistic bubble to the authoritative content). Same-worker delivery is instant via the per-worker `message_hub`; cross-worker delivery is filled by `services/messaging/relay.py` `message_relay` (per-worker ~1s DB poll on the `messages.id` watermark, deduped against the hub's delivered set).

 **Opt-in, default off, server-side.** When a user turns it on (profile **AI content correction** block, owner-only, saved at `POST /profile/{username}/ai-correction`), the prose they author is rewritten by the AI gateway. The per-user `ai_correction_sync` flag (0 = background default, 1 = sync) picks the **apply mode**: background rewrites the stored fields a moment after the write (never slows the request); sync makes the HTTP response wait until the correction is applied.
 
-- **Sync must never block the event loop (the self-deadlock trap).** The correction POSTs to the in-process gateway (`INTERNAL_GATEWAY_URL` = `localhost:{PORT}`), and the hooked content helpers are synchronous on the loop thread, so a blocking inline call self-deadlocks the (single) worker against its own gateway request - on a single worker that loop is the only thing that can serve the gateway request it is waiting on, so a blocking inline call deadlocks the worker until the httpx timeout, then fail-softs (server hangs, no correction). The fix: sync runs `_run_correction` via `loop.run_in_executor` (loop stays free), stashes the future on `request.scope[PENDING_SCOPE_KEY]`, and the `await_pending_corrections` middleware in `main.py` awaits it after the handler.

The fix: sync runs `_run_correction` on the dedicated `AI_APPLY_EXECUTOR` thread pool (`correction.py`, 4 workers) via `loop.run_in_executor` (loop stays free, and the default executor - shared with `asyncio.to_thread` password hashing at login/signup - is never occupied by blocking AI HTTP calls), stashes the future on `request.scope[PENDING_SCOPE_KEY]`, and the `await_pending_corrections` middleware in `main.py` awaits it after the handler. Never reintroduce a blocking inline correction on the loop thread.
 - **Field registry is the single source of truth.** `CORRECTABLE_FIELDS: dict[str, tuple[str, ...]]` maps each correctable table to its prose columns: `posts` -> `(title, content)`, `projects`/`gists` -> `(title, description)`, `comments`/`messages` -> `(content,)`, `users` -> `(bio,)`. `gists.source_code`, project files, and Gitea issues are intentionally excluded - code and external systems are never corrected.
-- **Choke entrypoint.** `schedule_correction(user, table, uid, request=None)` is the only thing handlers call (every hook passes `request`). It is a no-op unless: a user dict is present, `table` is in the registry, `user["ai_correction_enabled"]` is truthy, and the user has a non-empty `api_key`. In **sync** mode (`user["ai_correction_sync"]`) it calls `_run_inline_awaited`, which - only when a `request.scope` and a running event loop exist - submits `_run_correction` to `loop.run_in_executor` (off the loop thread) and stashes the future on `request.scope[PENDING_SCOPE_KEY]` for the middleware to await; if there is no request/loop it returns False and falls back to background.

Code-only and external paths (project files, Gitea) are deliberately not hooked.
 - **The gateway call is fail-soft.** `correct_text(api_key, prompt, text)` is synchronous (runs on the background worker thread), POSTs to `INTERNAL_GATEWAY_URL` with `model=INTERNAL_MODEL` via `stealth.stealth_sync_client`, authenticated with the user's own `Bearer` api_key (per-user attribution). It returns the ORIGINAL text on any error, empty output, or suspiciously large output (`len > len(text) * MAX_GROWTH_FACTOR + 200`, rejecting hallucinated expansion). `_run_correction` reads the row back, corrects each registry field that has non-blank text, writes only changed fields via `table.update(updates, ["uid"])` without touching `updated_at` (auto-correction is not a user edit) or the slug (slugs are permanent), and `clear_user_cache(user_uid)` when `table == "users"` so the corrected bio re-caches.
 - **Per-user usage aggregation (only on success).** `correct_text` returns `(text, usage)`; `usage` is parsed from the gateway's `X-Gateway-*` response headers (`_usage_from_headers`) whenever the upstream call returned 200 (cost was incurred, even if the corrected output was rejected), else `None` on any failure. `_usage_from_headers` captures the token and cost headers PLUS the timing headers `X-Gateway-Upstream-Latency-Ms` and `X-Gateway-Total-Latency-Ms` (as `upstream_latency_ms`/`total_latency_ms`), so each call's timing is metered. `_run_correction` accumulates the per-field `usage` into one `totals` dict and, when `totals["calls"] > 0`, makes ONE call to `database.add_correction_usage(user_uid, totals)` (a single `totals` dict, not positional args) - so a 2-field content item is a single aggregated write, and a failed/empty correction records nothing. `add_correction_usage` (and `add_modifier_usage`) delegate to the shared `database._add_usage(usage_table, user_uid, totals)`: a single atomic `INSERT ... ON CONFLICT(user_uid) DO UPDATE SET col = col + excluded.col` upsert against the `correction_usage` table (per-user running SUMS: `calls`/`prompt_tokens`/`completion_tokens`/`total_tokens`/`cost_usd`/`upstream_latency_ms`/`total_latency_ms`/`updated_at`, unique index `idx_correction_usage_user`, the two latency columns REAL default 0.0, all ensured in `init_db`). It is a derived counter table (NOT in `SOFT_DELETE_TABLES`, like `gateway_usage_ledger`) and is deliberately separate from `users` so accumulating never invalidates the auth/user cache. `database.get_correction_usage(user_uid)` (via `_get_usage`) returns the stored sums PLUS computed averages: `avg_tokens` (total_tokens/calls), `avg_upstream_latency_ms`, `avg_total_latency_ms`, `avg_tokens_per_second` (completion_tokens over total upstream seconds), and `avg_cost_usd`.

Written by the supervising worker, read by any worker. The heartbeat persists every `PERSIST_SECONDS` (8s, under the 15s `STALE_SECONDS` liveness window) and caches the row id so a persist is one UPDATE, not a `find_one` + UPDATE. `collect_metrics()` runs on its own slower `METRICS_SECONDS` cadence (15s default, per-class overridable - `AuditService` uses 300s because its metric is a `COUNT(*)` over the ever-growing audit table); between refreshes the last snapshot is re-persisted, and a `force` persist (transitions, run-now) always recomputes. Keep expensive aggregates out of the 1s tick: put them in `collect_metrics` and, if still heavy, raise the subclass `METRICS_SECONDS`.

 - **Admin-set cache invariant (load-bearing).** `_admins_cache` makes `get_admin_uids()` / `get_primary_admin_uid()` (hit on the projects-listing visibility filter, `_owner_is_admin`, and every primary-admin gate: `/dbapi`, backup-archive download) a dict lookup instead of a per-call `SELECT`. It is NOT the authorization gate - `is_admin(user)`/`require_admin` read the role off the user object (independently invalidated via `clear_user_cache`), so a stale admin set cannot grant access. But **any code that writes `users.role` MUST call `database.invalidate_admins_cache()`** (clears local + bumps the `admins` version), exactly like the soft-delete and `with db:` rules. Current role-write sites all do: `routers/admin/users.py` (role change), `cli.py` (`role set`), and `utils._create_account` (first user -> Admin). Omitting the call leaves the admin set stale for up to the 300s TTL.
 - **Deterministic / eventual caches skip version-sync on purpose.** Two caches need no `cache_state` name because correctness does not depend on cross-worker freshness: (1) `docs_prose._render_markdown` is an `@lru_cache` on the **static** prose source string (pure function of template content, so identical on every worker; changes only on deploy), and (2) `main._home_cache` (`TTLCache ttl=60`) memoizes the guest `/` blocks - the featured-news block (identical for everyone) and the latest-posts block **only for the no-block case**; a viewer with a non-empty block set bypasses the cache and is computed fresh, so the original block-filter semantics are preserved byte-for-byte and there is zero cross-user leakage. Worst case is a soft-deleted/edited public post lingering on `/` for <=60s. Use a plain `TTLCache`/`lru_cache` (no version name) ONLY when the value is deterministic or its staleness is purely cosmetic; anything whose staleness affects correctness or permissions MUST use the version-sync pattern above.

 **Per-owner self-learning memory is privacy-critical.** The `LessonStore` (reflect/recall) is **owner-scoped, never shared**: `LessonStore(db, owner_kind, owner_id)` filters every read/write by owner. The hub builds one per session over the same `owned_db` as the task store - the main `db` (table `devii_lessons`) for signed-in users (persistent, isolated, survives restarts) and a fresh `memory_db()` for guests (ephemeral, scoped to that web session). `forget_lessons` (agentic tool -> `LessonStore.clear()`/`delete()`) lets the user purge them; the system prompt forbids storing credentials/secrets in lessons. **Regression to avoid: do NOT share one `LessonStore` across sessions** - that leaked one user's reflected lessons (including credentials) into every other user's recall.
 
+**Lesson retention and deduplication.** Every `add()` deduplicates against existing active lessons via Jaccard similarity (threshold 0.70): a near-duplicate bumps the original's `hits` counter and refreshes `created_at` instead of inserting a new row. A per-owner cap (`devii_lessons_max_per_owner`, default 500, configurable on `/admin/services` and `site_settings`) is enforced on every insert: when exceeded, the oldest lessons are soft-deleted (`deleted_by="retention"`). Age-based pruning runs on `DeviiService.run_once()` (every 60s on the lock-owner worker): lessons older than `devii_lessons_max_age_days` (default 90, configurable) are soft-deleted across all owners. Both settings persist in `site_settings` and are seeded in `init_db`. The `devii_lessons` table is in `SOFT_DELETE_TABLES` for admin Trash restore/purge.
+
+**Quality signals.** Each lesson has a `rating` column (integer, default 0). The `lesson_rate(uid, value)` agentic tool (value 1 for useful, -1 for unhelpful) lets the agent self-rate lessons. In `_rebuild()`, lessons with `rating <= -3` are excluded from the BM25 index and therefore never returned by `recall()`. The `lesson_count()` tool reports active lesson count.
+
+**CLI:** `devplace devii lessons count` reports active/soft-deleted totals; `devplace devii lessons prune --all-owners|--username USER` soft-deletes old lessons; `devplace devii lessons clear --force` hard-deletes all rows. Rate-limiting guard: `run_once` swallows all exceptions so a bad schema never stops housekeeping.

 ## Reminders and scheduled tasks (persistent across reboot)
 
 `create_task` queues a self-contained prompt that a fresh agent runs later (`services/devii/tasks/`): `kind=once` (`delay_seconds` for relative, `run_at` UTC for absolute), `interval` (`every_seconds`), or `cron`. The per-session `Scheduler` ticks every 1s and executes due rows through the session's executor, so the result is broadcast to any connected tab and buffered (`type:"task"` frame) when the terminal is closed.

+Devii can ask the user for decisions through a gated tool surface instead of inventing HTML or channel-specific prose. Spec lives as the CA-IWP document; implementation is Devii-only under `services/devii/interaction/`.
+
+### Layers
+
+| Piece | Role |
+|-------|------|
+| `interaction/capabilities.py` | Maps session channel (`main`/`docs` -> `site-chat`, `telegram`, `cli`) to capability flags + limits; builds the compact `CHANNEL` / `CAPS` / `LIMITS` / `TOOLS` / `INTERACTION` fragment injected every turn. |
+| `interaction/schema.py` | Pydantic validation for `ui_prompt` args (widget catalog: confirm, choice, choice_multi, text, number, date, select, `//`, group). Untrusted model input is sanitized and capped. |
+| `interaction/broker.py` | Validates, assigns `interaction_id`, single-flight open interactions, routes to site / telegram / plain adapters, returns structured `{status, values, meta}`. |
+| `interaction/controller.py` | Dispatches `ui_prompt` / `ui_cancel` / `ui_notify` (`handler="interaction"`). |
+| `interaction/actions.py` | Catalog entries registered in `registry.py` as `INTERACTION_ACTIONS`. |
+| `interaction/markdown.py` + `parse.py` | Dual-surface markdown projection and plain/CLI reply parsers. |
+
+### Tool gating and preferences (admin default + user override)
+
+`DeviiSession._builtin_tools()` filters UI tools through `channel_context().tools`. Docs channel stays search-only (no UI tools). Open interaction (single-flight) exposes only `ui_cancel` plus preference tools.
+
+**Admin default:** Devii service ConfigField `devii_interactions_default` (bool, default on) on `/admin/services`. Guests always use this default.

+**User override:** column `users.interactions_enabled` (`-1` = inherit default, `0` = off, `1` = on). New signups insert `-1`. Resolution: `interaction/prefs.py` `effective_for(owner_kind, owner_id)`.
+
+**Surfaces (same fan-out as AI correction):**
+- Devii tools `interactions_get` / `interactions_set` (`requires_auth=True`; set accepts `enabled` or `reset=true` to inherit again). Always offered to signed-in users even when widgets are off, so they can re-enable.
+- HTTP `POST /profile/{username}/interactions` (owner-or-admin, form `InteractionsForm`), profile card + `InteractionsPref.js`, `docs_api` endpoint, audit `profile.interactions`, profile JSON keys on `ProfileOut`.
+- When effective is off, `ui_prompt` / `ui_notify` are absent from the tool list and the controller refuses them; the model must use degraded markdown menus.
+
+### Site-chat path
+
+`ui_prompt` blocks like client tools: session `_interaction_wait` emits `{type:"interaction", id, args}` on the WebSocket; `devii-terminal.js` mounts an `<ai-interaction>` tree via `createElement` (never model HTML), lazy-loads widget modules through `AiAutoload` (`static/js/autoload/AiAutoload.js`, allowlisted tag -> module map only), and replies with `{type:"interaction_result"}`. Router resolves via `session.resolve_interaction`. Custom elements live under `static/js/components/Ai*.js` with per-component CSS under `static/css/components/ai-*.css`. Light DOM only; `Application` boots the shell (`AiInteraction`, `AiStatus`, `AiActions`, `AiHelp`, `AiOption`) and starts the autoloader.
+
+### Telegram path
+
+`TelegramConnection` handles `type:"interaction"`: sends dual-surface plain text plus inline keyboard for confirm / single choice (`callback_data` short tokens). `TelegramBridge` registers a pending future **before** the chat lock so the next message or `callback_query` can resolve mid-turn. Worker `allowed_updates` includes `callback_query`; service routes `type:"callback"` to the bridge.
+
+### Plain / CLI path
+
+Broker uses `present_plain` or emits a plain menu and waits; `parse_plain_reply` accepts y/n, indices, value tokens, cancel.
+
+### System prompt
+
+Every non-docs turn appends `CA_IWP_SYSTEM_FRAGMENT` plus the live channel fragment from `_compose_system_prompt()`. Model rules: prefer `ui_prompt` when gated on; never invent HTML/CE tags; branch on `status` (submitted / cancelled / timeout / superseded / error).
+
+### Tests
+
+Unit coverage under `tests/unit/services/devii/interaction/` (capabilities, schema, markdown, parse, broker, controller) plus session tool-gating assertions and telegram callback emission. Mirror this layout for any extension.

 `GatewayService` (`services/openai_gateway/`) is an OpenAI-compatible LLM gateway (the ported `openai5.py`), mounted at `/openai/v1/*` (`routers/openai_gateway.py`, prefix `/openai`). It is a **service that serves an HTTP endpoint** rather than a loop.
 
-- The router is thin: it calls `service_manager.get_service("openai").handle(request, subpath)`. `POST /v1/chat/completions` runs the full gateway (vision augment -> model override -> forward -> optional SSE re-emit via `_fake_stream`); `POST /v1/embeddings` forwards to the configured embeddings upstream (`handle_embeddings`, no vision/streaming); `/v1/{path:path}` is a transparent passthrough to the upstream base. Disabled -> 503, unauthorized -> 401, upstream connection failure -> 502.

Disabled -> 503, unauthorized -> 401, upstream connection failure -> 502.

 Every gateway response (chat, embeddings, passthrough; success and error) carries `X-Gateway-*` headers describing that single call: `Model`, `Backend`, `Prompt-Tokens`, `Completion-Tokens`, `Total-Tokens`, `Cache-Hit-Tokens`, `Cache-Miss-Tokens`, `Reasoning-Tokens`, `Cost-USD`/`Input-Cost-USD`/`Output-Cost-USD` (dollars), `Cost-Native` (1 if the upstream returned a native cost), `Tokens-Per-Second`, `Upstream-Latency-Ms`, and `Context-Window`/`Context-Utilization` when the model's window is known, plus the timing headers `X-Gateway-Upstream-Latency-Ms`/`X-Gateway-Total-Latency-Ms`. `GatewayUsageLedger.record(...)` RETURNS the computed ledger row (or `None` on failure); each handler's `finalize` closure maps it through `usage.usage_response_headers(row)` and attaches it to the returned `Response` (`resp_headers`). The single denied path with no upstream call (embeddings disabled) carries no headers. This is what lets any caller read its own spend - the AI correction worker reads `X-Gateway-Cost-USD`/token headers off its own correction call to accumulate per-user totals (see "AI content correction" in the root `CLAUDE.md`).

+- **Header name:** `X-App-Reference`.

-**No matching route = `None` overlay = byte-identical legacy behavior** - this is the "nobody feels the transformation" guarantee: `molodetz`/`molodetz~embed`/`molodetz-img-small` and every existing caller are byte-identical when no route matches. A route with a blank provider overlays only model+pricing(+vision), keeping the default upstream url/key.
+**No matching route = None overlay = model fallback.** When no route matches, the overlay returns `None` and the handler's model selection logic falls back to the default configured model (`gateway_model` for chat, `gateway_embed_model` for embeddings, `gateway_image_model` for images). The unknown model name is discarded, not forwarded upstream. This means an unknown or misspelled model name never causes a 4xx from the upstream - it is gracefully downgraded to the default. The `force_model` guard and the built-in `molodetz`/`molodetz~embed`/`molodetz-img-small` aliases are still respected before the route check: `force_model` or empty/named-alias model -> default directly; known model -> route resolution; unknown model with no route -> default fallback with a log message.

 - **Overlay + computation.** `chat_overlay`/`embed_overlay` propagate all of these into the per-request cfg dict under `gateway_*` keys exactly like the existing price fields (section above); `usage.pricing_from_cfg` reads them generically (defaulting to `None`/`0`/disabled when absent), so **Layer A (the single global flat Pricing config fields) never gains these dimensions** - only a `gateway_models` route can enable them, preserving the "no matching route = byte-identical legacy behavior" guarantee. `usage.compute_cost` selects tier1 vs tier2 per rate component (`_tiered_rate`) based on whether `norm["prompt"]` (billable input tokens) exceeds the threshold, then applies the off-peak discount (`_effective_rate`/`_off_peak_active`, UTC wraparound-aware) to whichever rate was selected. **The response header format and `compute_cost`'s return shape (`total, input_cost, output_cost, native`) are unchanged** - this is purely an internal rate-selection step before the existing input/output split math runs; a native upstream `cost` (OpenRouter) still overrides the modeled total exactly as before.
 - **Migration.** New `gateway_models` columns are added via `has_column`/`create_column_by_example` in `routing.ensure_tables()` (the `CREATE TABLE IF NOT EXISTS` DDL string alone would never reach a pre-existing table - see the `database/CLAUDE.md` column-ensure idiom).
 - **Admin UI.** `/admin/gateway`'s model-route form has a "Tiered / off-peak pricing (optional)" subsection; off-peak start/end render as `<input type="time">` (converted to/from UTC minutes-of-day by `GatewayAdmin.js`), and the routes table shows `tiered`/`off-peak` badges when a route has either dimension configured.
-- **DeepSeek's real pricing is already the tier-1 shape, not a new dimension.** DeepSeek's actual API (verified against `api-docs.deepseek.com/quick_start/pricing`) bills three flat per-1M rates - cache-hit input, cache-miss input, output - with no current context-length tier or off-peak window for the V4 models; that shape was already fully modeled by the pre-existing `chat_cache_hit_per_m`/`chat_cache_miss_per_m`/`chat_output_per_m` fields before this section's tier2/off-peak fields existed. `routing.seed_default_deepseek_routes()` (called once from `database.migrate_ai_gateway_settings()` at the end of `init_db()`) idempotently inserts two ready-made routes - `deepseek-v4-flash` (`$0.0028`/`$0.14`/`$0.28` per 1M, 1M context) and `deepseek-v4-pro` (`$0.003625`/`$0.435`/`$0.87` per 1M, 1M context) - only when that `source_model` row does not already exist, so a caller or Devii can request either name explicitly and get correctly-priced, decoupled from whatever the single global `gateway_model` default happens to be set to (switching that global setting between the two real models does NOT retroactively fix the flat Pricing config fields - the seeded routes are the model-agnostic, always-correct way to reference a specific priced model). Neither seeded route sets the tier2/off-peak fields (DeepSeek does not use them today); an admin can add them later on the same row if DeepSeek (or any other provider routed here) introduces such pricing.

The `molodetz`/`molodetz-pro` aliases are the public model names; `GET /v1/models` is served locally from these `source_model` rows (not proxied upstream), so it publishes exactly the models the gateway accepts. Neither seeded route sets the tier2/off-peak fields (DeepSeek does not use them today); an admin can add them later on the same row if DeepSeek (or any other provider routed here) introduces such pricing.
