feat(studio): a conversational assistant, served off the DO admin dispatch#429prisis wants to merge 41 commits into
Conversation
Plan 364, W1 and W2. The Studio's three assistant RPCs are one-shot and run on the shard DO's admin dispatch, which is single-threaded — `sql-assistant.ts` holds a 15 s deadline on one inference precisely so a hung model cannot pin it. A conversation cannot be given a deadline that small, so `__lunora_admin__:aiChat` is intercepted and served at the WORKER instead, the way `getAuthAuditLog` already is. It never touches the dispatch. Answers the plan's first open question along the way. The engine's only import was `shared/sql-readonly`, so rather than create a `@lunora/runtime` → `@lunora/do` dependency edge it moves to `shared/sql-assistant.ts`, which is what that folder is for. `@lunora/do`'s public surface is unchanged — the snapshot does not move — and both tsconfigs were already set up for `shared/`. W2's caps are server-side, because the op takes whatever body an admin bearer sends: a turn cap and a character cap, since either alone is escapable, dropping oldest-first and reporting that it did. Every prior turn is fenced as untrusted input INCLUDING the entries claiming to be earlier assistant output — a re-sent transcript is caller-supplied by definition and the browser could forge any of it. No retry loop on a chat turn: unlike the structured RPCs there is no machine-checkable shape to retry against, so a re-roll would only spend the deadline. Replies are prose; any SQL in one reaches the editor on a click and passes the same gate as anything else. W1's gate is tested against a deliberately SLOW model double. Against one that resolves immediately the test passes even if the op were forwarded to the DO, which is the trap the plan warns about.

Plan 364 W3. A chat panel below the SQL editor, on the same availability latch the prompt bar uses — with no `AI` binding it renders nothing rather than a control that can only fail. The transcript lives in React state, not storage. A console chat is a scratchpad; persisting it would mean a retention policy and another store of raw statements outliving the browser, which is the finding that made SQL history opt-in. Nothing here executes. A reply is prose, and the only path from it to the editor is the operator pressing Insert — what lands there still has to be Run like anything they typed. Only a fenced ```sql block is offered: "any line starting with SELECT" would hand prose to that button. The block scanner is a linear split rather than the obvious regex, which is polynomial-backtracking — a model reply is exactly the input not to hand an ambiguous matcher. An unterminated fence yields nothing, because half a statement is not one.

Plan 364 W4. A turn may ask for `describeTables` or a `runSql`, dispatched server-side inside the turn and fed back as a fenced observation — so the model reads its own tool results through the same untrusted boundary as everything else. Only tools with an existing gated admin op behind them, dispatched through the same forwarder the studio uses, which keeps the security question to "does the existing gate still hold" rather than "is this new capability safe". A `runSql` is gate-checked in the engine BEFORE dispatch, and a failing one is refused in-loop and told to the model as a refusal — never retried into a different statement, which would let it probe the gate for one that slips through. Answers two of the plan's open questions. The tool reads the shard the console has open, named by the caller and echoed back in `toolCalls`, so a reply is never ambiguous about what it read. And reaching the call cap answers with what it has, marked `partial`, rather than erroring away the work already done. The forward carries the admin bearer verbatim instead of resolving an identity: an admin RPC is authorized by the bearer and resolves to a null identity by design, so resolving one here computes a value the DO ignores.

W1–W4 shipped; the assistant works end to end. W5 does not, and the reason is worth writing down rather than leaving as a TODO someone re-costs from scratch: its (S) rating assumed streaming could reuse `client.stream()`, and it cannot. That primitive rides the subscription WebSocket and is answered by the DO (`shard-do.ts:4535`), so using it would route the conversation back through the single-threaded admin dispatch — the STOP condition this plan exists to honour. Nothing else is borrowable either: `text/event-stream` appears nowhere in runtime or studio. W5 is a transport workstream and needs its own plan.

Review found the chat panel rendering English directly, so a translator cannot reach it. `reasonMessage` now takes `t` and calls it with literals rather than returning a string to translate, which keeps every id statically known — the reason `dashboards-panel`'s `kindLabel` is written the same way. Fixed in `sql-assistant-bar.tsx` too.

…istant
Two review passes, and the headline is that the feature did not work. The client
sent `schema: []` hardcoded and never sent `shardKey`, so the model was told to
use only listed tables and given none, and every tool read went to a Durable
Object literally named "" rather than the shard the console had open. Two
comments in this branch said opposite things about that, which is how it
survived. The panel now passes the editor's own schema, the key travels in the
args, and an absent key means the ROOT shard like every other dispatch path.
The untrusted fence was escapable. One symmetric marker meant an ODD number of
injected markers flipped the pairing, putting everything after it outside the
region — and the docblock's defence (fields "length-capped well below any useful
escape") was false by a factor of sixty. Markers are asymmetric now and `capped`
neutralises both at the one choke point every untrusted field routes through.
This matters more than it did: a tool result carries rows written by the app's
own end users, not just the admin's own text. The test that claimed to prove this
was vacuous — it asserted an ordering that held with no fencing logic at all.
`generateChat` did not catch `runPrompt` rejections, so a routine model timeout
escaped as a 500 and discarded any completed tool work, contradicting both its
own docblock and the plan's "degrade, never throw".
Tool calls forwarded the raw `authorization` header, so an Access-authorized
admin — who presents no bearer — had every one answered 403 by the shard, and the
error envelope was fed to the model as if it were data. They now go through
`resolveAdminForwardContext`, check the status, and decode the wire envelope
instead of handing the model `{"result":{…}}` with bigint sentinels.
A missing `AI` binding degrades with `no-ai-binding` rather than a 400, so the
sticky availability latch hides the surface — a 400 left the panel rendered and
every send failing, the exact failure the latch exists to prevent.
Also: the client dropped `toolCalls`/`partial` (the fields that say what a turn
read) via a drifted duplicate type, now imported from the engine; refusals were
all attributed to `runSql` including those that named no tool; `dispatchChatTool`
moved into `ai-chat-rpc.ts`, deleting the forward-declared `let`; the no-tools
branch folded into the loop; grounding facts are length-capped; and the
concurrency test's shard double now serializes, without which its timing
assertion held no matter where the op was served.
Plan §3's row-value contract is revised in place rather than left contradicting
W4, and the "never retried" comment now says what the code enforces.

The chat assistant was unreachable: `aiChatBinding` was declared on `WorkerOptions` and read by the handler, and passed by nothing. The three one-shot assistant RPCs reach `env.AI` from inside the shard DO, but this op is served at the WORKER by design, so it cannot get there any other way — it degraded to "no AI binding" on every app regardless of what was bound. Codegen now reads `env.AI` into the option at the one place worker options are assembled, mirroring how the DO reads it. Unconditional: an app with no binding yields `undefined`, which is exactly the not-configured signal the op expects, and the studio's sticky latch then hides the surface rather than showing one that cannot work. The playground gains the binding so the feature can actually be exercised there. It has no local emulation — Wrangler proxies it to Cloudflare — so the assistant needs an authenticated account even in dev; everything else in the playground still runs offline. Golden fixture and all thirteen example `_generated/app.ts` regenerated, each by exactly the one emitted line.

It shipped as a bare input wedged between the query plan and the results tabs: no label, no icon, nothing to open it, and vertical space taken whether or not anyone was talking to it. It read as part of the results toolbar rather than as its own thing. Now an "Assistant" toggle sits beside the split-view control, hidden without an `AI` binding like every other assistant affordance, and the panel is a right-hand column that is closed by default. Beside the workspace rather than below it because the two compete otherwise: the transcript stays visible while the operator reads a result and edits the query the assistant suggested, which is the reason to have it in the console at all instead of a modal. The panel also gains a heading saying what it is and that nothing runs until you insert and run it. The no-binding test now asserts the TOGGLE is absent rather than the panel — with the panel closed by default, asserting on it would have passed even with the availability latch broken. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RiK7HSTeqimrtkE63A6NEP
A "Fix this" affordance already existed — in the prompt bar at the TOP of the
editor, which is the one place an operator reading an error at the bottom of a
full-height editor cannot see it. The button now sits on the failure.
It opens the assistant with the statement and the database's message as the
question, rather than silently rewriting the draft: an error you do not
understand is not fixed by a statement you did not read either, and a transcript
lets the operator follow up ("why does that column not exist?").
The seeded question is keyed by id so the same error can be asked about twice,
guarded by a ref so a re-render never re-asks, and queued out of the effect body
— setting state synchronously there forces a second render before paint, so the
panel would open empty and then fill.
The effect sits with every other hook, above the early return. Behind it, it ran
only while the panel was open, so opening the panel changed the hook count and
React threw "rendered more hooks than during the previous render".

The plan and the index both still said W1-W4, three waves after that stopped being true, and my memory has this exact failure logged twice before: an execution table that reads TODO after shipping is worse than no table. §11 records W9 (markdown with images dropped, per-turn tool calls, seeded starters, per-message actions, readAdvisors). §12 records the three defects found while building it, none of them in the feature: the standalone bundle shipping development React and unable to stop, the playground AI binding killing the whole E2E suite, and Access-only admins locked out of every worker-served admin op.

`LUNORA_AI_OPT_IN` decides how much of a deployment the Studio's assistant
may read, and until now it had no readout anywhere: an operator whose
assistant refused to read a table saw the bare word "refused" and a tier
name they could neither inspect nor find the var for.
Three changes:
- `__lunora_admin__:aiAvailable` moves from the shard DO to the worker and
now answers `{ available, level }`. It is built from the SAME deps object
as `aiChat`, so the level it reports is `deps.optInLevel()` — the call the
tool gate itself makes. The shard used to narrow `env.LUNORA_AI_OPT_IN` a
second time, which made the readout a second answer rather than a report
of the enforced one. `ShardDO.aiBinding` still reads the var for its own
one-shot ops, through the same `asOptInLevel`, as a reader.
- Settings gains a read-only "AI assistant data sharing" card: the current
level, the whole ladder with the tools each rung unlocks (derived from
`TOOL_LEVEL`, not restated), and the var to change. In Settings rather
than beside the assistant because `disabled` hides every assistant
surface, so a readout living there is unreachable to the one operator who
needs it. No control raises the level — a level the browser could pick
would not be a gate.
- A tool refused for being above the level now carries `needs` on its
`toolCalls` entry, so the panel can say which tier it wanted, where the
deployment sits, and which var moves it. That reason previously reached
only the model.
BREAKING CHANGE: `AiAvailableResult` gains a required `level`, and
`aiAvailable` is served at the worker rather than on the shard.

Nothing measured whether the chat assistant's answers were any good: a prompt, model or tool change could make every one worse and every test still pass, because the tests assert plumbing (was the tool dispatched, was the statement refused) and never what the model was told. Adds a 13-case behavioural eval set for `shared/ai-chat.ts`, run through `@lunora/testing`'s `evaluate` and scorers against a scripted `AiRunBinding` — deterministic, no Cloudflare account, no token. Each run is rendered as a record of what the engine did (system prompt, final user prompt, tools dispatched, refusals with reasons, outcome) and the case's rubric scores that, so the scorers judge behaviour rather than prose. The set covers grounding, the data-sharing ladder, tool dispatch, the two refusal paths, the tool-call cap, fence neutralisation, the transcript budget, and all four degrade arms. Grading the model itself is left out on purpose: it needs a live model and a judge, and a CI gate that needs an API token is a gate that gets disabled. Lives in `tests/ai-evals` rather than `packages/runtime` because the devDependency that would need is a build cycle — `@lunora/testing` reaches `@lunora/runtime` back through agent → mail → react → client. Adds `absentScorer` to `@lunora/testing`: every existing scorer asserts presence, which cannot express "never dispatched the write" or "never offered the tool this tier forbids" — the expectations a refusal is made of.

Two gaps plan 364 left open, closed together because they are the same complaint from opposite ends: a chat turn read rows nobody asked it to, and it had nothing true to say about the framework it was reading them in. ## Operator approval before a tool reads rows `runSql` dispatched inside the loop with no operator gesture anywhere. Plan 364 §3 recorded that honestly as "the deliberate substance of W4" and narrowed the boundary it claimed to hold; the boundary was still wrong. Row VALUES, chosen by the MODEL, reached an inference provider because a deploy-time tier said rows were permissible in principle. The turn now STOPS. On a `runSql` request with no valid approval it returns `pendingApproval` — name, statement, ticket — instead of dispatching; the panel renders the statement with Allow / Deny; the answer starts a follow-up turn carrying the decision. `MAX_TOOL_CALLS` is unchanged, so stopping costs one extra round trip, not a new budget. Shapes weighed and rejected. A second op the panel polls for a decision is W5's transport problem in a smaller hat, and W5 is blocked. Having the panel pre-approve a statement before sending puts the decision before the model has proposed anything, which is nothing to judge. Blocking server-side is not available: the op is a single request/response and holding it open until a click arrives is a long-poll this transport does not have. Forgery. Everything the browser sends on this op is caller-supplied, including a boolean claiming the operator said yes — so the approval carries no statement of its own. It carries a ticket: an HMAC the server minted over the exact statement it proposed, verified against the statement the model asks for on the follow-up turn. An approval the browser invents unlocks nothing, and a real ticket replayed against a different statement unlocks nothing either. The key is random per isolate because the only other secret this op has is the admin token and the browser holds that; a recycled isolate therefore invalidates outstanding tickets, and that failure is one-directional — an unrecognised ticket reads as "not approved", so the card comes back and nothing runs unapproved. The ceiling is marked at the code. Ordering. `classifyStatement` runs first, unchanged, so a write is refused in-loop and never becomes a card asking an operator to approve something the gate would refuse anyway. Deny is a real answer rather than a local dismissal: the model is told it was declined and answers from what it has. Every arm returns a reason the UI renders; nothing throws. Only `runSql` requires it, recorded as an exhaustive `TOOL_APPROVAL` record so a new tool must decide. `describeTables` and `readAdvisors` return no row values. `readLogs` is the close call and the answer is no: its scope is fixed and its disclosure was already chosen at deploy time by selecting `schema_and_log`, so a card there would say the same thing every turn with no parameter to weigh — and a click-through habit is precisely what would get the `runSql` card approved unread. Friction belongs where the disclosure is chosen. ## A knowledge base the model can load The assistant knew the operator's schema, logs, advisories and rows, and nothing whatsoever about Lunora, so it answered framework questions by inventing APIs — confidently, into a console that then offers to insert the result into an editor. `loadKnowledge` looks up a digest DERIVED from the documentation rather than a second copy of it: `scripts/build-ai-knowledge.js` compiles `apps/docs/src/content/docs` into `shared/ai-knowledge-data.ts`, and the existing `check-generated-files` gate fails the build when the committed digest stops matching the docs. What travels is an index — title, the reviewed frontmatter description, the `##` headings (largely API names in these docs), and the page URL — because one tool result is capped at 2,000 characters by `fitToBudget` and every byte ships in every deployed Worker: 28.6 KB of data, 9.9 KB gzipped, against the 50 KiB `worker-size.json` allowance. A topic matching nothing returns the table of contents rather than an empty list, since an empty result is a dead end the model can only answer from memory. The advisor's rule text is deliberately NOT duplicated here — a finding already carries its own `description` and `remediation` through the existing `readAdvisors` tool, so a second store of it is exactly the parallel doc set that drifts. Tiered at `schema`, the lowest rung a tool can hold: it discloses nothing about the deployment. A "docs only" rung below it would gate nothing, since `disabled` already ends the turn before any tool runs. It is also the one tool answered inside the engine, so `ChatToolRunner` and the worker's op table are keyed by a new `ForwardedToolName` — a tool added with neither an op nor an in-engine answer stays a compile error. ## Tests New coverage on both. The security arms were verified to FAIL without the fix: trusting the client's `allow` flag instead of the MAC breaks the forged-ticket, wrong-statement and expired-ticket tests, and removing the stop entirely breaks seven.

…ether Three parallel workstreams off the same base. Two conflicts were real design overlaps rather than text collisions, and both sides' intent survives: `shared/ai-chat.ts` — one branch added `needs: AiOptInLevel` to a level refusal so the studio can tell "fixable by editing one wrangler var" from "malformed"; the other added `pendingApproval` so a turn can STOP at a read rather than dispatch it. Independent additions to the same result type; kept both. `plans/364` — both appended a section numbering itself §11, and both labelled waves. Renumbered into one document: §11 stays W9 (it shipped first), the approval/knowledge section becomes §12 as W10–W11, and the findings section moves to §13 and now covers W6–W11. One genuine cross-branch break, which only exists when both land: the eval set's `TOOL_RESULTS` is an exhaustive `Record<ChatToolName, unknown>`, and the other branch added `loadKnowledge` to that union — so the record stopped compiling. That is the record doing its job. Fixed by keying it on `ForwardedToolName` instead, which is truthful rather than merely compiling: `loadKnowledge` is answered inside the engine and never reaches a tool runner, so a fixture entry for it would describe a dispatch that cannot happen. A forwarded tool added without a fixture still fails to compile. Verified on the combined tree, not just per branch: studio 1116 / runtime 944 / do 554 / testing 154 / ai-evals 1, repo-wide lint:types, prettier, eslint --max-warnings=0, build:packages:prod → api:check + dist:check, package.json sort.

`lunora eval` could not load any eval file that imports project source, in this repo or in a user's app. The handler `import()`ed a discovered `*.eval.ts` bare. Node's native TypeScript execution strips types but changes no resolution, while every Lunora project compiles under `moduleResolution: "bundler"` and therefore writes extension-less relative imports, so the first relative import inside the eval file -- or anything it pulled in -- died with `ERR_MODULE_NOT_FOUND`. The gap is resolution, not syntax, so a transform-only tool cannot close it. `jiti` resolves and transforms, is pure JavaScript with no per-platform native binary for consumers to download, and works across the whole supported Node range instead of only where native type-stripping is unflagged. It is imported lazily inside the eval handler (itself lazy-loaded via the command's `loader`), so no other subcommand pays for it: ~19 ms to import plus ~1 ms to construct, and only on `lunora eval`. Removes the Node-floor abort path the bare `import()` needed, along with its fixture and test: with a loader in place there is no version of Node in `engines` where every discovered eval fails identically. A file that fails to load is now that eval's own row, like any other crash. Also drops the packem `dynamicVars` carve-out, since the handler no longer takes a dynamic `import()` of a runtime-built path. Regression cover shells out to the built binary on plain Node. That is the only honest seam: Vitest resolves and transforms whatever it is handed, including a file reached through a runtime `import()`, so an in-process test of the runner passes whether or not the shipped command can load anything -- verified by patching the fix back out and watching the new test go red with the original error.

The conversational assistant answered in one piece: the operator pressed
Send and watched a spinner for as long as the turn took, which is up to
four inferences when the model reaches for tools.
`__lunora_admin__:aiChat` now answers `text/event-stream`. Three frame
kinds, and only one of them is the answer:
- `data: {"type":"delta","text":…}` — the reply as the model produces it.
- `data: {"type":"tool","call":…}` — that round asked for a tool instead
of answering, so the prose it streamed was a preamble the turn
discards and a reader clears its draft.
- `event: complete` — the whole `ChatResult` in the same
`{ result: encodeWire(...) }` envelope the op answered with before,
carrying reply, toolCalls, partial, truncated, pendingApproval and
every degrade reason unchanged.
The asymmetry is the safety property: narration carries nothing a caller
must act on, so a turn that never reaches its terminal frame has
produced nothing to commit. `LunoraClient.streamRpc` rejects on a body
that ends early rather than resolving with what arrived, and the panel
holds the streamed text apart from the transcript and appends only on a
resolved answer — so an interrupted stream leaves no partial turn.
Real token streaming, not simulated: `runPrompt` passes `stream: true`
and consumes the binding's SSE body, with the one existing deadline now
covering the whole generation rather than only the handshake. A binding
that answers with a whole object anyway degrades to a single delta
carrying the entire reply.
The tool block is never streamed. Tokens are held back by one character
less than the fence length, so a request that opens across several
tokens is recognised before any of it reaches the screen.
Streaming REPLACES the whole-answer path rather than sitting beside it:
two transports would be two places for the admin gate, the data-sharing
level and the approval ticket to drift. `assertAdmin` still runs first,
before the stream is constructed, so a refused caller gets a JSON error.
SSE framing moves to `shared/sse.ts`, shared with `@lunora/server`'s
route pump, which had the only copy — one writer format for the one
reader that parses both.

Two one-shot assistant helpers on the existing engine, both shard-DO admin ops registered on `aiAdminHandlers` alongside `aiGenerateSql` / `aiTableFilter` / `aiChartConfig`, both reached through `ShardDO.aiBinding()` so a deployment whose data-sharing level is `disabled` degrades without a second gate. `aiNameQuery` drafts a title and a one-line description for a saved SQL query from the statement alone. The query library could not be renamed at all before this — every saved query read "Untitled query" forever — so the rename form is new too, and the drafted label only fills its fields: Save is the accept step, and nothing is written until it is pressed. `SavedQuery` gains an optional `description`. `aiCronExpression` turns a described schedule into a Cron Trigger expression. The answer is validated against the DEPLOYABLE grammar, not the authoring one: `@lunora/scheduler` delegates to `cron-parser` and so tolerates 6-field seconds-leading expressions, the `@daily` macros and the Quartz operators, warning rather than throwing — latitude meant for a hand-authored escape hatch, and the wrong bar for an answer nobody has read. `shared/cron-expression.ts` checks the narrower 5-field subset Cloudflare actually accepts, so a schedule `wrangler deploy` would reject is discarded instead of pasted. The prompt states the one-minute floor for the same reason: `interval.seconds` is rejected outright upstream. It sits above the cron-triggers list, which stays read-only — triggers are compiled into the worker, so the honest output is an expression to copy into `lunora/crons.ts`, which is the step operators were doing by hand. Both hide on the existing availability latch, degrade rather than throw, and reuse the one inference primitive, one retry policy, one deadline and one untrusted fence.

Plan 364 §4 deferred RLS policy authoring to "if and only if tool-calling
grows a write tool", and §8 STOPs on "a tool gains a write". The approval
gate that trade was waiting on now exists, so this picks the work up
against it — and the honest answer, on this framework's actual shape, is
that there is no write for it to gate.
A policy here is not DDL. It is `definePolicy({ table, on, when })`,
collected by `definePolicies([...])` and attached to ONE procedure at a
time with `.use(rls(policies, { roles }))`. The `when` predicate is a
TypeScript closure returning a WhereInput, true or false; nothing
serialises it and nothing stores it. Codegen statically discovers
`(table, on, procedure, file)` plus role and permission names and serves
those read-only — which is all the Studio's inspector has ever had,
because it is all there is.
Applying one means writing a `.ts` file under `lunora/` and rerunning
codegen. The only thing that does that is `/__lunora/policy-scaffold`, a
Node handler the dev hosts mount on a loopback bind, carrying no admin
token because nothing else can reach it. `aiChat` is served at the
WORKER: no filesystem, no toolchain, no route to that host. A "write
tool" could therefore only mean the browser applying an edit after a
click — and a server-minted ticket proves nothing about an edit the
server never performs, so the approval gate would be theatre bolted onto
a confirm dialog. The STOP condition is untouched rather than argued
around: no tool gained a write, and TOOL_APPROVAL records that decision
as false with the reasoning beside it, in the exhaustive record that
makes skipping the decision a compile error.
What ships instead is propose-and-apply:
- `readPolicies`, tiered at `schema` in TOOL_LEVEL, forwarded to the
inspector's existing `rlsPolicies` op. The model could not see coverage
at all, so it guessed at it. Policy metadata is names about the schema
— no rows, no log lines — so it sits beside describeTables and
readAdvisors and needs no card: the request names nothing, so every
call returns the same deployment-wide answer and there is no parameter
for an operator to weigh.
- The authoring contract in the system prompt. The knowledge digest
carries titles and headings and no code, and the rule it introduced —
never state a framework API unless the digest showed it to you —
correctly stopped the model writing a policy at all. Left to memory it
answered with Postgres CREATE POLICY: confident, and wrong in a way an
operator could paste into the console beside it.
- "Ask the assistant" on the RLS inspector, seeded with the coverage on
screen and gated on the read having LANDED — building the seed
mid-flight asked "you have no policies at all" about a deployment with
plenty.
The boundary holds by construction: that page has no editor so no Insert
is offered, the reply reader only ever accepts a `sql`-tagged fence, and
the scaffolder still refuses to author a `when` body itself. A runtime
test asserts the whole turn touches exactly one op and that it is the
read one; that assertion is what fails the day someone wires a write.
The ticket's content binding was verified by neutering `ticketApproves`:
the forged-ticket, replayed-against-a-different-statement and expired
cases all fail without it.

Found by an agent seeing this fail once in six runs under whole-suite load, and
it is a real race rather than contention noise.
The assertion was `toContainEqual({ columns: [], table: "messages" })` — the
empty column list included. But the schema probe resolves independently of the
chat call, so under load its columns can land FIRST and the shape stops matching.
The test then fails for a reason that has nothing to do with what it is checking.
What it is actually about is that grounding reaches the server at all, so it now
asserts the table is named and says nothing about columns.

The console could draft a statement and explain one, but not change one: the operator with a working query who wants "add a limit and order by created_at" had to ask the chat panel and paste the answer over their own work. ⌘/Ctrl+I in the editor now arms an instruction box over the selection — or the whole draft when the caret is collapsed — and answers with a unified line diff to accept or reject. The chord is bound on the textarea rather than globally, so it cannot collide with the console's Ctrl+`, the palette's ⌘K or the sidebar's ⌘B, and it is inert on a deployment that cannot run the assistant. The draft is not written until Accept, so Reject and Escape restore what was there by construction rather than by remembering to put it back. An armed rewrite is dismissed when the draft is edited or the tab switched, because its span is a pair of offsets into the text it was armed over. No new op and no new dependency: `aiGenerateSql` gains an optional `editSql` arm (distinct from `failedSql`, which tells the model the statement broke and invites it to invent a fault), so the rewrite passes the same read-only gate as every other drafted statement and lands in the editor UNRUN. The line diff is one LCS table over a statement the engine already caps at 2,000 characters. Colour is not the only signal in the diff: each row carries a +/- marker and a visually-hidden word, and focus moves to Accept when the proposal arrives so the decision is reachable from the keyboard.

# Conflicts: # packages/runtime/__tests__/ai-chat-rpc.test.ts
`controller.close()` sat behind an `open` flag that TypeScript can only see assigned once, so the guard was provably dead code — and it was also the wrong guard: `open` goes false when an enqueue throws, which is the one case where closing is most likely to throw too. Catch instead, the same way the enqueue path already does. Plus three test-only lint fixes: two await-expression member accesses and a truthiness matcher on a string.

The baseline was set at `850f31d08` and had not moved since, so the 50 KiB allowance was absorbing drift from several changes at once and the next person to add anything would have failed for reasons mostly not theirs. Measured rather than estimated, by building the same reference Worker at two points: - committed baseline 412.9 KiB gzipped - `alpha` today 428.7 KiB → +15.8 KiB predates this branch - this branch 447.1 KiB → +18.4 KiB is ours So the drift is roughly half-and-half, not the "~21 KiB pre-existing" a first estimate suggested. Ours is intended and identifiable: the chat engine and its tool loop, the SSE transport, the approval ticket, and the docs knowledge index (~10 KiB gzipped on its own, and deliberately an INDEX rather than page bodies for exactly this reason). The script's own instruction is to accept intended growth explicitly "so the increase is visible in review rather than buried" — this commit is that acceptance, and the numbers above are what makes it visible rather than a silent bump. The check passed at 447.1 against the old 462.9 ceiling, so this is not a fix for a failure. It is re-arming the signal: without it the next change inherits 15.8 KiB of headroom and a failure it did not cause. Also carries the API snapshots for this wave — `streamRpc` on the client, and the two new `ADMIN_FUNCTIONS` keys on shard-engine and studio. All additive.

Plan 364, W1–W4. The Studio gets a chat panel beside the SQL editor that can answer questions about the database, look things up with read-only tools, and hand a statement to the editor. W5 (streaming) is blocked — see below.
Where it runs, and why that is the whole point
The three existing assistant RPCs run on the shard DO's admin dispatch, which is single-threaded —
sql-assistant.tsholds a 15 s deadline on one inference precisely so a hung model cannot pin it. A conversation cannot be given a deadline that small, so__lunora_admin__:aiChatis intercepted and served at the worker, the waygetAuthAuditLogalready is. It never touches the dispatch.The plan's open questions, answered
@lunora/runtimeimport the engine from@lunora/do? Neither package depends on the other, so it would have created a new edge. The engine's only import wasshared/sql-readonly— it was already a zero-dependency unit — so it moved toshared/sql-assistant.ts.@lunora/do's API snapshot does not move, confirming the relocation is invisible.toolCalls.sessionStorage. A console chat is a scratchpad.partial, rather than erroring away work already done.Security posture
runSqlis gate-checked before dispatch; a failing one is refused in-loop and reported to the model, never retried into a different statement.W5 is blocked, and was mis-sized
client.stream()rides the subscription WebSocket and is answered by the DO (shard-do.ts:4535) — using it would route the conversation back through the dispatch this plan exists to avoid, which is its own STOP condition.text/event-streamappears nowhere in runtime or studio. W5 is a transport workstream and needs its own plan; §8b records this.Verified
lint:types,api:check,lint:generated, eslint, prettier. Runtime 916, studio 1079,@lunora/do554.W1's gate is tested against a deliberately slow model double — against one that resolves immediately the test passes even if the op were forwarded to the DO, which is the trap §7 warns about. I also confirmed the suite fails when the interception is removed, and that the tool-gate test fails when the gate is bypassed.
