-| "`build-agent` is called with the Slack credential" | "The Agent uses the Slack credential the user has" |
-| "The sub-agent adds a tool for the lookup" | "The Agent can look up the order status when a user asks for it" |

-The sections below add the Agent-specific parts. Do not skip the general rules

-## Ask for the target suite first
-
-Follow "Ask for the target suite first" in
-[create-instance-ai-eval](../create-instance-ai-eval/SKILL.md). Do it after the
-LangTracer preflight and before you source or draft anything. If the request
-already names a suite, state it and do not ask. Otherwise ask, in autonomous
-mode too, in the same message as the autonomy question.
-
-For Agent cases, recommend
-[Instance AI capabilities — agents](https://lang-tracer.n8n-maintenance.workers.dev/suites/10)
-(slug `agents`). Offer `baseline` as well: the Instance AI (INS) team monitors
-it and it runs nightly. Get the full list from `list_suites`. Use the suite the
-driver picks in every push command, in place of `agents` in the examples below.
-Keep the `agents` dataset and the `data/agents/` directory. They do not depend
-on the suite.
-
-## Set the autonomy level first
-
-Follow "Set the autonomy level first" in
-[create-instance-ai-eval](../create-instance-ai-eval/SKILL.md). Ask the driver
-for *autonomous* or *checkpoint* mode before you source or draft anything. The
-four gates are the same: selection, shape and expectations, calibration, push.
-
-## Source the case from a real thread
-
-The best Agent cases come from a real conversation. Discover the conversation
-with LangTracer. Author a synthetic case from what you learn.
-
-1. List candidates: `list_conversations` with `usedAgentBuilder: true`. Do not
-   use `source: "agent-builder"`. That pool is a different product, has
-   unscrubbed payloads, and has no Agent snapshots.
-2. List what the thread did to the Agent: `list_conversation_agent_snapshots`.
-   `target-resolved` is the state that a turn opened on. `config-updated` is the
-   state after the builder changed it.
-3. Pick the shape from the snapshot sequence (next section).
-4. Fetch the state to seed with `get_conversation_agent_snapshot`. Seed from the
-   `target-resolved` row of the turn under test.
-5. Read the raw turn before you write any expectation. Follow
-   "First reproduce, then reclassify" in the general skill.
-
-Two snapshot patterns to look for:
-
-- A `target-resolved` hash that differs from the previous `config-updated` hash.
-  The user edited the Agent in the UI between turns. This is the best seed for a
-  repair or update case.
-- A run of turns that each end in `config-updated`. The user added one rule per
-  turn. Use it for a "new rule does not erase old rules" case.
-
-Credentials arrive as `[redacted]`. Instructions and skill bodies do not. Scrub
-the prose before it enters a case. See the `agents` section in
-[case-shapes.md](../create-instance-ai-eval/case-shapes.md) (the `agents` seed section).
-
-## Pick the shape: create or update
-
-| Shape | Question it answers | How to write it |
-|---|---|---|
-| **Create** | Does the builder make the right Agent from a fresh request? | One user turn. No seed. Assert on the Agent artifact. |
-| **Update** | Does the builder change only what the user asked for? | `seed.agents` with the Agent before the change. One live turn with the change. Assert on the new behavior and that the untouched parts survive. |
-| **Repair** | Does the builder find the cause of a failure and fix it? | Seed the broken Agent. The live turn reports the failure. Assert on the cause found and the fix applied. |
-| **Incremental rules** | Do earlier rules survive when a new rule lands? | Seed the Agent after several rules. Add one conflicting or overlapping rule. Assert that the old rules are still in force. |
-
-Rules that apply to all four:
-
-- An update that rebuilds the Agent from scratch is a failure. Assert on a
-  specific untouched instruction, tool, or skill that must still be there.
-- Write the conversation in English, even when the source thread is not.
-- Trim to the fewest turns that reproduce the behavior. Do not copy a long
-  thread.
-- Put only the live turn in `conversation`. Put earlier turns in `seed.messages`.
-
-## Confirm the precondition fired
-
-A pass can mean the builder did the right thing. It can also mean the situation
-never happened. Check before you trust a green.
-
-- For "the builder did not do X", confirm that it reached the turn where X was
-  possible. A builder that never edited the Agent passes "did not delete the old
-  rule".
-- For a repair case, confirm that the seeded Agent really has the defect. Read
-  the seeded config in the rendered artifact.
-- For an update case, compare the seeded config with the final config. Confirm
-  that the requested change is the only difference you expected.
-- For a "say you cannot" case, confirm that the tool or data was really missing
-  in the run.
-
-## A red is a finding
-
-Follow "A red is signal" in the general skill. For Agent cases, add this:
-
-1. Classify the red as a product gap, a harness limitation, or non-determinism.
-2. Keep a product-gap red. Start the case `description` with
-   `Capability-gap finding:`.
-3. **Propose a Linear ticket for the Agent team.** The Linear team is named
-   `Agent`. Propose the ticket. Do not create it unless the driver says go.
-   Follow "Capability gap → propose a Linear ticket" in the general skill. Also
-   check whether the gap already has a ticket.
-   - Write the ticket in English. Use Simplified Technical English, as
-     [AGENTS.md](../../../AGENTS.md) requires. Translate the user's words. Do
-     not paste them.
-   - This repository is public. Keep customer names, company names, and real
-     URLs out of the ticket. Describe the use case in neutral words.
-   - Link the LangTracer case and the source thread. Do not copy raw user
-     messages or agent instructions from the thread.
-   - Reproduce the gap first. This is a default, not a hard rule. Propose a
-     ticket only after a case is red on a real build. Quote the failing
-     expectation and the judge reason. Follow "Reproduce first" in the general
-     skill.
-   - The driver may approve an exception, for example when the harness cannot
-     reach the mechanism after about three attempts. Then the ticket must say
-     "Not reproduced in the eval. Based on trace analysis."
-4. **Check the builder's own guidance for the gap.** Read the files that steer
-   Agent Builder:
-   `packages/cli/src/modules/agents/builder/agents-builder-prompts.ts`,
-   `packages/cli/src/modules/agents/builder/prompts/`, and
-   `packages/cli/src/modules/agents/builder/skills/`. Also read the Instance AI
-   orchestrator prompt in `packages/@n8n/instance-ai/src/agent/system-prompt.ts`.
-   If none of them covers the failing situation, add that to the ticket as a
-   proposed prompt or skill change.
-5. Propose the smallest added line first. Do not delete existing guidance to fix a
-   gap. A measured case: adding one line fixed a routing gap, and deleting two
-   lines did not.
-6. Every prompt or skill change needs a before and after measurement. The new
-   case is the "before" run. Run it again after the change. Use `--iterations 5`.
-
-When the failure is in the Agent's runtime (for example a channel that cannot
-report an error), the builder cannot see it. The right fix is often a builder
-instruction to say so and stop guessing. Write that as a `processExpectations`
-item on the final response.
-
-## Publish and link
-
-Follow "Share links, never bare ids" and "Link the pushed case to its source" in
-the general skill. For a sourced Agent case:
-
-- Report the case, the suite, and the source thread as links. Use the
-  `https://lang-tracer.n8n-maintenance.workers.dev/test-cases/<id>` form.
-- Call `update_test_case` with `sourceThreadId`, `expectedBehavior`, and
-  `failurePattern`.
-- Add a capability tag with `add_case_tags`.
-- Push a case whose *build* is wrong with `--set-kind capability_gap` into a
-  suite of that kind. If no such Agent suite exists, tell the driver. Do not put
-  it in a `regression` suite.

-## Ask for the target suite first
-
-**Before you source, draft, or run anything, ask the driver which LangTracer
-suite receives every eval you create in this session.** Ask this in both
-autonomy levels, including autonomous mode. Never pick the suite yourself and
-never default silently. A case pushed to the wrong suite runs in the wrong CI
-lane and alerts the wrong team.
-
-Ask the suite question and the autonomy question together, in one message.
-Recommend `baseline`:
-
-- `baseline` (recommended): the general corpus. The Instance AI (INS) team
-  monitors it, and it runs nightly.
-- Any other suite, such as `agents` or `node-gauntlet`: call `list_suites` and
-  offer the live list. Do not use a hardcoded list, because suites are added
-  and retired.
-
-Rules:
-
-- The driver's answer applies to all cases in the session. Do not ask again per
-  case.
-- If the driver already named a suite in the request, state it back in one line
-  and continue. Do not ask again.
-- Check that the suite kind matches the case. Push a case with a wrong build
-  (`capability_gap`) only into a suite that allows that kind. If the suite does
-  not allow it, tell the driver and ask again.

-## Context cases (long conversations, token cost, compaction)
-
-A context case asks whether the agent still works once the conversation is
-long. Two questions, two mechanics.
-
-### The judge already has the token numbers
-
-Every case's judge context carries token ground truth, so no new field is
-needed to grade cost:
-
-- Each transcript turn header reads
-  `Turn 2 (3 steps, 47446 tokens in [41220 cached], 812 tokens out)`.
-- A **Total** block sums every LLM step across the whole build, main run and
-  resumes, plus a cache read/write split and a **Fixed overhead** line — the
-  opening step's input, which is instructions and tool schemas plus one user
-  message, so it reads as the floor cost of any turn on that instance. Use it
-  to separate "the prompt got bigger" from "this conversation got expensive".
-
-So `processExpectations` may reference consumption directly. Write them as
-statements about *behaviour the numbers reveal*, not as thresholds:
-
-```json
-"processExpectations": [
-  "The agent answers the second question without calling get_node_details on the Notion node again — it read that schema in turn 1 and the answer needs nothing new.",
-  "Turn 2's input tokens are mostly cache reads, which is what an unchanged prefix looks like. A turn that re-reads the history from scratch shows a cache-read share near zero."
-]
-```
-
-Absolute token budgets rot: a prompt edit moves every number and the case goes
-red for a reason that has nothing to do with the agent. Grade the *shape* —
-what got re-read, what came from cache, which turn is the expensive one.
-
-Two limits to know before you write a cost expectation:
-
-- It needs `N8N_INSTANCE_AI_RUN_DEBUG_ENABLED=true` on the instance under test.
-  Without it the blocks render `(no run debug captured)` and the expectation is
-  unjudgeable — it fails or passes at random.
-- The capture hooks **only the orchestrator's own stream**. A workflow build
-  runs inside that loop, so a workflow case's numbers are its real cost. A
-  delegated **Agent** build (the `build-agent` tool) runs on a separate stream
-  with no hooks, so its tokens are missing from every block. Don't write a cost
-  expectation on an `data/agents/` case.
-
-### `requiresMemoryCompaction` — grade the post-compaction window
-
-Observational memory compacts a long thread: an Observer summarises it into
-observation rows, the summary is rendered into the system prompt, and the early
-turns are masked out of the agent's window. A case that tests whether a decision
-*survives* that has a setup problem — production compacts at 30k tokens of
-visible message content, which is a conversation too long to hand-author.
-
-Set the flag and the harness handles it:
-
-```json
-"requiresMemoryCompaction": true
-```
-
-Two things happen, both per-thread, so no other case in the run is affected:
-
-1. The harness sends a low observer threshold with every turn of that thread
-   only: **1,000 tokens** of visible message content, the request field's floor.
-   The seed plus the live turns must cross it, or the observer never runs — a
-   short seed does not test memory, it reports **not judged** (below). Size the
-   seed generously; a few real turns of tool output cross 1,000 tokens easily.
-   The Observer's prompt, masking and cursor logic are the production ones at
-   any threshold.
-2. After the build, the harness checks the premise actually held. If it did
-   not, every expectation on the case is reported **not judged** — an
-   `incomplete` verdict, excluded from scoring, not a red.
-
-The premise check is the point of the flag. Uncompacted, the raw early turns
-are still in the window, so the agent answers off them and every expectation
-passes for free — a green that tests nothing.
-
-The evidence is structural. `GET /rest/instance-ai/eval/threads/:threadId/memory`
-returns the observation rows and the compaction cursor from their own tables. A
-cursor means the observer ran and everything up to `lastObservedMessageId` is
-masked out; the rows are what replaced it. Missing either, the case had nothing
-to test and is reported not judged. Nothing reads the system prompt, so this
-needs **no debug flag** and a prompt or SDK rename cannot quietly turn "never
-compacted" into the answer.
-
-The judge never sees the premise check — it grades the conversation, not whether
-the harness configured the scenario. A misconfigured lane must not read as a
-quality regression.
-
-### Grade the summary, not just the reply
-
-The judge *does* see the observation rows, as ground truth:
-
-```
-## Observational memory after compaction (ground truth — do not recount)
-
-- [CRITICAL] User ruled OUT the native Slack node; will post through the HTTP
-  Request node instead, because the workspace is pinned to a legacy Slack API
-  version. Do not revisit.
-- [CRITICAL] Alert fires when queue depth goes above 4700 items.
-```
-
-So write expectations at **both** layers:
-
-```json
-"processExpectations": [
-  "The observational-memory block retains the alert threshold as 4700 queued items. A summary that keeps the topic but loses the number is the specific failure this looks for.",
-  "In its reply to the final turn, the agent gives the alert threshold as 4700 queued items."
-]
-```
-
-The first grades the memory system, the second grades the agent. Grading only
-the reply is weaker than it looks: the agent can answer correctly from the
-unmasked tail, or guess well, and the case goes green while memory dropped the
-detail. The `[MARKER]` is the Observer's own priority label, so "retained as
-CRITICAL" is checkable too.
-
-### Writing the conversation
-
-The shape that makes a compaction case real:
-
-1. **State the anchors once, in a `user` turn near the start of the seed**, and
-   never restate them. Anything the agent repeats later lands *after* the
-   cursor and survives for the wrong reason.
-2. **Make live turn 1 off-topic.** Its answer must not re-surface the anchors
-   into the post-cursor window. Compaction runs at the end of it.
-3. **Ask for the anchors back in live turn 2.** That turn runs against the
-   compacted context.
-4. **Force the antecedent** — a lost anchor must produce a *confident wrong*
-   answer, not a vague one. "Posting goes through HTTP Request, not the native
-   Slack node" works because the Slack node is the obvious guess. "The
-   threshold is 4700" works because a guess reaches for 5000. See
-   [negative expectations need a forced antecedent](SKILL.md#core-principle-all-shapes).

 ### Primary Keys
 
-Every table needs a primary key. **Use an integer key by default.** Read the options below in order. Use the first option that fits. Do not skip an option only because you like a later one better.
+Every table needs a primary key. Choose the type in this order:
 
-1. **Integer (default)** — `column('id').int.primary.autoGenerate2`. Use this for every new table. Use a different option only when one of its conditions is true. Integer keys are small and make joins fast. `autoGenerate2` uses Postgres `IDENTITY`. Do not use `autoGenerate`. It uses `serial`, which is deprecated.
-2. **UUID** — `column('id').uuid.primary`. Use this only when one of these conditions is true:
-   - The application must know the ID before the insert. For example, the client makes the ID.
-   - The ID is in a URL or a public API. Users must not see how many rows exist or guess other IDs.
-
-   **You must use UUIDv7.** Make the ID in application code with the `uuid` package: `import { v7 as uuidv7 } from 'uuid'`.
-
-   Why: a UUIDv7 starts with a timestamp. Thus, new rows go near the end of the index. A UUIDv4 is random, for example `randomUUID()` from `node:crypto`. New rows go to random positions in the index. This splits index pages and makes the index larger.
-
-   A UUIDv7 does not give an exact creation order. Two IDs made in the same millisecond can sort in the wrong order. Clock differences between hosts can also cause this. If you need the exact order, sort by a timestamp column.
-
-   Do **not** chain `.autoGenerate2` on `.uuid`. The DSL throws an error. The database default makes a UUIDv4. Also, `uuid_generate_v4()` needs the `uuid-ossp` extension. Some managed Postgres services, such as Supabase, do not have it. Use `.uuid`, not `.varchar(36)`.
-3. **String** — `column('id').varchar(36).primary`. Use this only when one of these conditions is true:
-   - The entity already uses IDs in a format that is not a UUID. For example, the public API or the UI already shows nanoid IDs for this entity.
-   - The UI shows the ID to users. A UUID is too long to read, copy, or type.
-
-   Entity IDs are usually nanoids with 16 characters.
-
-**Give a reason for every key that is not an integer.** Write the reason in the PR description. Reviewers will ask for it. These reasons are not sufficient:
-- "Other tables use string IDs."
-- "This module already does it this way."
-- "We might need it later."
-
-**These options apply to a generated `id` column only.** A join table that only links other tables does not need an `id` column. Use its foreign-key columns as a composite key (see below). A foreign-key column always has the same type as the key that it refers to.
+1. **Integer** — `column('id').int.primary.autoGenerate2`. Preferred for new tables: compact, fast joins, no ordering surprises. `autoGenerate2` uses Postgres `IDENTITY` (preferred over the deprecated `serial`-based `autoGenerate`).
+2. **UUID** — `column('id').uuid.primary`. Use when IDs are generated client-side, exposed in URLs, or need to be unguessable. Generate UUIDs in application code via `randomUUID()` from `node:crypto`; do **not** chain `.autoGenerate2` on `.uuid` (the DSL throws — `DEFAULT uuid_generate_v4()` fails on managed Postgres like Supabase because it needs the `uuid-ossp` extension in `public`). Use `.uuid` instead of `.varchar(36)`.
+3. **String** — `column('id').varchar(36).primary` for IDs whose format isn't a UUID (e.g. nanoid-style IDs). Convention: nanoid length 16 for entity IDs.
 
 **Keep ID-column types consistent across related tables.** Mixing `uuid` and `varchar(36)` for what is "the same kind of ID" creates JOIN footguns.

-# Environment variable docs
-
-The JSDoc above every `@Env('...')` property is exported almost verbatim into
-the [environment variables reference](https://docs.n8n.io/deploy/host-n8n/configure-n8n/basic-configuration/use-environment-variables)
-on docs.n8n.io. The generated table has four columns: variable name,
-description, data type, default. Your JSDoc is the description column. The
-reader is a self-hosting operator, not an n8n developer.
-
-Follow the [n8n docs style guide](https://docs.n8n.io/contribute/contribution-guide-for-n8n-docs/style-guide-for-n8n-docs)
-for these comments. It overrides the ASD-STE100 rule in `AGENTS.md` for this
-one case. The rules below are the parts of that guide that matter for a
-one-paragraph description.
-
-## Rules
-
-- **Every `@Env` property has a JSDoc.** No exceptions. A missing comment
-  ships as an empty description cell.
-- **Write for the operator.** Say what the setting does, when to change it,
-  and what happens when it's unset or wrong. Don't explain why the code is
-  written the way it is.
-- **No code references.** No file names, class names, function names,
-  constants, license keys, or other internals the reader can't open. Values
-  the operator types into the variable are fine and often needed, for example
-  a credential type ID like `googleOAuth2Api` or a mode like `postgresdb`.
-  The test: would the operator paste this into a config file, or would they
-  need the source to know what it means? Details for developers go in a
-  regular `//` comment on the implementation, not in the JSDoc.
-- **No attack scenarios.** Say what the setting protects, not how an
-  attacker would exploit it. This is a public page.
-- **Don't repeat the default.** The default renders in its own column. Don't
-  write "Defaults to true" or "Default: 1 hour". Do say what the unset state
-  means when it's not obvious, for example "When unset, n8n uses the Redis
-  host".
-- **State units and formats.** Say "in milliseconds", "in bytes", "a
-  comma-separated list", "a JSON object". The data type column only says
-  `Number` or `String`.
-- **Use allowed values when the set is small.** "One of `sqlite`,
-  `postgresdb`." For a list, show one inline example in the sentence.
-- **No JSDoc tags.** No `@example`, `@default`, `@see`, `@deprecated`. The
-  exporter copies the tag name into the docs. Put the example or the
-  deprecation notice in a sentence instead.
-- **Product names:** "Gateway credits", not "n8n Connect" or "AI Gateway".
-  "Publish a workflow", not "activate". `n8n` is always lowercase.
-- **Style:** present tense, active voice, second person. Use contractions.
-  No em dashes, use a comma or a new sentence. No "e.g." or "i.e.", write
-  "for example" and "that is". Spell out zero to nine, numerals from 10.
-  Values the operator types stay numerals, for example "Set to 0".
-  Sentence case. One idea per sentence. End every sentence with a period.
-- **Plain words:** "use" not "utilize", "lets you" not "allows you to", cut
-  "powerful", "seamless", "simply", "it's important to note".
-- **Length:** one to three sentences. If the setting needs more, the extra
-  belongs in a docs page the comment can't link to yet; keep the comment to
-  what fits a table cell.
-
-## Examples
-
-Bad, as found in the generated docs:
-
-```ts
-/**
- * Instance-level enablement for n8n Connect (AI Gateway). Licensed instances
- * are enabled by default; false opts out. Budget / free allowance still comes
- * from the license (`quota:aiGatewayBudget`).
- */
-```
-
-Wrong product name, a restated default, and an internal license key. Good:
-
-```ts
-/**
- * Whether Gateway credits are available on this instance. Set to false to
- * turn them off on a licensed instance. The credit allowance comes from your
- * license.
- */
-```
-
-Bad:
-
-```ts
-/**
- * Time to live in milliseconds for Redis cache entries. Set to 0 to disable
- * expiry. Default: 1 hour.
- */
-```
-
-The default is already in the table. Good:
-
-```ts
-/**
- * Time to live in milliseconds for Redis cache entries. Set to 0 to keep
- * entries until Redis evicts them.
- */
-```
-
-Bad:
-
-```ts
-/**
- * Comma-separated list of credential types for which overwrites are skipped
- * when the credential has been customized.
- * @example `N8N_SKIP_CREDENTIAL_OVERWRITE=zohoOAuth2Api,salesforceOAuth2Api`
- */
-```
-
-The `@example` tag lands in the description as literal text. Good:
-
-```ts
-/**
- * Comma-separated list of credential types to skip when applying credential
- * overwrites, for example `zohoOAuth2Api,salesforceOAuth2Api`. n8n skips an
- * overwrite only when a user has already changed one of its fields.
- */
-```
-
-Bad:
-
-```ts
-/**
- * Bind OAuth credential callbacks to the browser that initiated the flow.
- * When enabled, a session-scoped `n8n-oauth-binding` cookie is set on flow
- * initiation and verified on callback. Defeats phishing attacks where an
- * attacker injects an OAuth authorize URL into a victim's browser to land
- * tokens on the attacker's credential.
- */
-```
-
-Attack narrative and an internal cookie name on a public page. Good:
-
-```ts
-/**
- * Whether an OAuth credential connection must finish in the same browser
- * that started it. When enabled, n8n rejects the callback if it arrives
- * from a different browser.
- */
-```
-
-## Review checklist
-
-When you review a PR that adds or changes an `@Env` property, check each
-comment against this list and quote the fix in the review:
-
-1. JSDoc present.
-2. No code identifiers, file names, or internal keys.
-3. No default restated.
-4. Units, format, or allowed values stated.
-5. No JSDoc tags.
-6. No em dashes, Latin abbreviations, or filler words.
-7. Reads correctly as a sentence in a table cell with no surrounding context.

+`v1/handlers/`, wired through `openapi.yml` with `x-eov-operation-*` and request
+types in `packages/cli/src/public-api/types.ts`. Treat these as migration targets,
+not templates.
 
-- `uploadLimits: () => MultipartUploadLimits` is a thunk, read once the route
-  handles its first request (not at startup) — read live config inside it
-  (e.g. `Container.get(GlobalConfig)`), don't inline a literal.
-- The route's `@Body` DTO validates text fields merged with uploaded files,
-  not `req.body` alone. A text field and a file share the same flat object;
-  a file field uses `publicApiUploadedFileSchema` (`@n8n/api-types`) — a
-  multer-file-shaped schema that documents itself as `{ type: 'string',
-  format: 'binary' }`. Several files under the same field name become an
-  array.
-- An unknown field (one the DTO doesn't declare, on a `{ strict: true }` DTO)
-  fails with `Unexpected form field "<name>"` — not the default "unrecognized
-  keys" wording.
-- Multer parsing errors map to these statuses: `413` for a size or count limit,
-  `500` for `LIMIT_UNEXPECTED_FILE`, `400` for any other multer error, and `500`
-  for anything else (a malformed body). The `500` is not masked, because it is a
-  `ResponseError`. A missing boundary gives `400` with `multipart file(s) required`.
-- The body is parsed **after** every auth/scope/license/quota gate and
-  **before** controller/route middlewares — a caller those gates would reject
-  never has their (possibly huge) body read off the socket, and a middleware
-  that reads `req.body` sees it already parsed.
-- `/discover` shows no request schema for a multipart route (same as a legacy
-  multipart route today) — a client can't assume a JSON schema it never gets.
-- The generator documents the body under the `multipart/form-data` content
-  key (not `application/json`) and adds `413` alongside `415` to the route's
-  documented responses automatically.

-Everything above lives in `packages/cli/src/public-api/media-types/`, one

-`RequestBodyHandler` in `media-types/request-body/`, and register it in
-`REQUEST_BODY_HANDLERS` — the registry, resolver, generator and `/discover`
-need no change, since they all read the handler, not the media type.
-
-## Binary response bodies
-
-`@ApiResponse(status, { mediaType, description?, headers? })` declares a
-success body that the controller method returns as `{ body, headers? }`, for
-example an `application/gzip` stream. The framework treats options whose
-`mediaType` is in `BINARY_RESPONSE_MEDIA_TYPES` as a binary response.
-`mediaType` accepts only those types.
-
-- `body` is a `Buffer` or a `Readable`. The method returns the result and never
-  writes to `res`.
-- `headers` holds the response headers. Every header declared in `headers` must
-  be in the result. A missing header fails the request with a `500`. Matching is
-  case-insensitive.
-- The registry checks the headers, then sets the declared status, the headers,
-  and `Content-Type: <mediaType>`. A header in the result cannot replace the
-  `Content-Type`.
-- A stream's first chunk is read before any header is set. So a stream that
-  fails before its first chunk gives the normal JSON error response, with no
-  binary `Content-Type`. A method that throws before it returns does the same.
-- After the first chunk is sent, an error ends the response. A client that
-  disconnects is not an error, and the framework destroys the stream.
-- A method that returns no binary body fails with a `500`.
-- The generator documents the body as `{ type: string, format: binary }`
-  under the `mediaType` content key, with the description and headers.
-  The description defaults to `Operation successful.`.

-The runtime part is `sendBinaryResponse` in

+- Prefer migrating to `@PublicApiController` over extending the handler.
+- Preserve the public contract: path, method, scopes, status codes, response
+  shape, and pagination.
+- Move HTTP concerns into the controller and business orchestration into the
+  shared service; keep the controller a thin HTTP boundary. If the legacy
+  handler was itself already just a thin wrapper around an internal
+  `@RestController` (calling its methods directly, e.g.
+  `Container.get(SomeController).createThing(req, res, payload)`), the new
+  public controller can call that same internal controller directly — no need
+  to duplicate its validation/business logic.
+- A route must be served by either the EOV handler or a controller, not both —
+  the build's `mergeDecoratorDocument` (`v1/openapi-gen/generate.ts`) throws on
+  a path+method declared by both sides. Remove the legacy wiring (its path's
+  `$ref` entry in `openapi.yml`, the `x-eov-operation-*` handler, and its
+  `handler.ts`) only after the new controller is registered, `pnpm build`
+  regenerates the spec cleanly, and tests are updated.
+- Fully delete the migrated legacy files: the handler's `.ts`, its
+	`spec/paths/*.yml` and `spec/schemas/*.yml`, and any now-dead request type
+	in `packages/cli/src/public-api/types.ts`. Then check
+  `v1/shared/spec/schemas/_index.yml` and `v1/shared/spec/parameters/_index.yml`
+  for entries that `$ref` one of the deleted schema/parameter files — those are
+  separate from the path's own `$ref` in `openapi.yml` and are easy to miss;
+  left dangling, the next bundle fails on a broken `$ref`.
+- If the legacy handler gated on a license (`isLicensed('feat:x')` middleware),
+  `@Licensed('feat:x')` now replicates that for a controller route (see the
+  decorator table in [SKILL.md](SKILL.md#declaring-a-controller)) — but only for
+  a single feature. If the legacy check was an any-of/all-of over several flags
+  (e.g. `LicenseState.isProvisioningLicensed()`), `@Licensed` can't express
+  that; replicate it manually in the controller instead, don't drop it - this
+  is exactly what the internal `provisioning.controller.ee.ts` and
+  `role-mapping-rule.controller.ee.ts` already do, since neither uses
+  `@Licensed` for that reason.
+- As a legacy file drops repository access / the `export =` tuple, remove its
+  entry from the `off` allowlists for `no-repository-in-public-api-handler` and
+  `require-public-api-controller` in `packages/cli/eslint.config.mjs` (shrink-only
+  — never extend them).
+- For complex legacy-only, multipart, or non-standard endpoints, study the
+  nearest existing handler first.
+- Keep each field in its original position when you extract a request shape shared
+  by two routes, and destructure out the ones a route doesn't take. The generator
+  emits properties in shape order, so a moved field rewrites the `*.generated.yml`
+  of a route the PR wasn't changing.

-
-1. From a local checkout, add an SSH host for your codespace:
-
-   ```bash
-   pnpm session ssh-config

-
-   The command creates or starts the codespace. It writes the host
-   `n8n-codespace` to `~/.ssh/n8n-codespace.conf` and includes that file from
-   `~/.ssh/config`.
-2. In the desktop app, add an SSH connection to the host `n8n-codespace`.
-3. Open the folder `/workspaces/n8n`, or a worktree under `/workspaces`.
-
-The desktop app installs its own Claude Code on the codespace and signs in
-with your desktop account. Sessions continue when you close the app. They stop
-when the codespace stops.

-- **Run `pnpm session ssh-config` again after you recreate the codespace.**

-## Local OpenCode clients
-
-Run these commands from a local checkout. The TUI runs on your laptop. The
-OpenCode server, repository, tools, and builds run in the Codespace. Browser
-mode opens the remote web interface through a local connection.
-
-```bash
-pnpm session:opencode fix-flaky              # resume that workspace's latest conversation
-pnpm session:opencode fix-flaky --web        # open it in a browser
-pnpm session:opencode fix-flaky --new        # start a new conversation in that worktree
-pnpm session:opencode --web --port 4100      # override the default browser port
-pnpm session:opencode --help
-```
-
-For the TUI, install the same OpenCode version as the remote server. The
-`OPENCODE_VERSION` argument in the [Dockerfile](Dockerfile) pins the version
-for new images:
-
-```bash
-npm install -g opencode-ai@<version>
-```
-
-Use npm, not pnpm. The package gets its binary from a `postinstall` script.
-pnpm does not run that script by default.
-
-The launcher checks both versions. It reports a mismatch with both version
-numbers before it opens the TUI. An existing Codespace can have a different
-version. Install that version locally, or use `--web`. Browser mode does not
-need a local OpenCode install.
-The launcher sends its bootstrap code over SSH, so an existing Codespace does
-not need a rebuild to use this connection method.
-The remote server loads the shared OpenCode harness that the Codespace
-post-start command installs. The local harness setup above is not required for
-these commands.
-
-The command prepares the worktree, starts or reuses one server, opens an SSH
-tunnel, and connects the client. Each workspace opens its own conversation: the
-most recently updated one in that worktree. A conversation moves to the front
-when it receives a message. Switching to a conversation without sending a
-message does not move it. Switching to another workspace's conversation does
-not change what this workspace opens next. `--new` starts a new conversation
-instead. It preserves the worktree and the old conversation.
-
-- **Exit the TUI** with `/exit` or its quit shortcut. The launcher closes its
-  tunnel. The remote server stays running.
-- **Disconnect browser mode** with `Ctrl-C` in the launcher terminal. Closing
-  the browser tab does not close the tunnel. Keep the launcher running while
-  you use the browser.
-- **Reconnect** with the same command after a network interruption. After a
-  Codespace stop, the command restarts the server and opens the workspace's
-  most recently updated conversation.
-  A stop terminates running tools. It does not resume interrupted commands.
-- **Browser mode uses local port 4096 by default.** Use `--port` to override it.
-  TUI mode selects an available port unless you specify one.
-  A fixed browser port preserves the browser origin across runs.
-  An occupied fixed port causes an error. It does not stop the existing listener.
-- **Use model and permission controls in the client.** The new connection uses
-  the remote OpenCode configuration. It does not force the legacy `--auto` mode.
-  For the old CLI flags, use `pnpm session:opencode fix-flaky --legacy --model <model>`.
-
-Both server and tunnel bind to `127.0.0.1`. The server uses a generated password.
-The TUI receives it through its environment. Browser mode uses a local proxy
-that adds authentication and rejects requests from other browser origins. The
-proxy supports streamed responses, attachments, and terminal WebSockets. The
-password does not appear in the URL or terminal output. Other processes on
-your laptop can access the local browser proxy while it runs. Do not forward
-this proxy or the OpenCode server port to other machines.
-
-The server enables only OpenRouter. It reads `OPENROUTER_API_KEY` when it starts.
-It enables OpenCode code mode by default to reduce the initial tool context.
-Browser mode opens the workspace's most recently updated conversation directly.
-The web UI stores opened projects in browser storage. If a new-session page
-shows **New project**, open `/workspaces/n8n` there once. Keep the same browser
-port when you reconnect to preserve this selection.
-
-The server runs in the detached tmux session `n8n-opencode-server`. Its log is
-`/workspaces/.n8n-opencode/server.log`. That directory also holds the server
-credentials. It is readable only by its owner.
-An unhealthy server produces an error without stopping active work. Inspect
-the log through `pnpm session:shell`. To restart it after checking active work,
-run `tmux kill-session -t '=n8n-opencode-server'` in that shell. Then reconnect.
-Restart the server after changing provider secrets, server configuration, or
-the pinned harness release.

-- The launcher supports macOS and Linux. On Windows, run it in WSL. If the
-  browser does not open automatically, open the printed URL yourself.
-- Local clipboard and attachment controls depend on the client, terminal,
-  file type, and model. A laptop file path does not copy a file to the Codespace.
-  Use a supported attachment control or copy the file with `gh codespace cp`.
-- Tools and local MCP processes run on the Codespace. Laptop configuration,
-  browser sessions, and files do not sync automatically.
-- Workspace names identify worktrees. Two agents that use the same name share
-  files. Separate conversations alone do not isolate edits.
-- The server survives a client disconnect while the Codespace stays running.
-  Codespaces idle timeouts still apply. An open tunnel is not a guarantee that
