# Findings: Session Data, Agent/Model Changes, and Shared Sessions

## 1. Session Data Structure

### Session Table Schema
**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/session/session.sql.ts` (lines 11-35)

The `SessionTable` stores:
- `id`, `project_id`, `parent_id`, `slug`, `directory`, `title`, `version`
- `share_url` - link for sharing
- `summary_*` fields (additions, deletions, files, diffs)
- `revert` - JSON for undo tracking
- `permission` - JSON ruleset for permissions
- Timestamps: `time_created`, `time_updated`, `time_compacting`, `time_archived`

**Critical finding: The session table has NO `agent` or `model` fields.** Agent and model are **not stored on the session itself**. They are stored on **individual user messages**.

### Session Info Type
**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/session/index.ts` (lines 114-155)

The `Session.Info` Zod schema confirms no agent/model fields exist at the session level.

### Message Structure - Where Agent/Model Live
**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/session/message-v2.ts`

**User message** (lines 345-369): Contains `agent: z.string()` and `model: z.object({ providerID, modelID })`. Each user message records which agent and model were active when it was sent.

**Assistant message** (lines 391-438): Contains `agent: z.string()`, `modelID: z.string()`, `providerID: z.string()`, plus `mode` (deprecated alias for agent).

Messages are stored in the `MessageTable` (lines 37-48 of `session.sql.ts`) with a `data` JSON column holding all the message-specific fields.

Findings: What Happens to Session Data When Agent/Model Changes

Key Insight: Agent/Model Are Per-Message, Not Per-Session

The session table itself has no agent or model fields. Instead, each user message records which agent and model were active when it was sent (session/message-v2.ts:345-369). This is the fundamental design: agent/model are message-level properties, not session-level state.

Step-by-Step Flow When Agent/Model Changes

  1. Client sends a prompt with the new model and/or agent fields.
  2. A new user message is created (session/prompt.ts:954-978) with the new agent/model baked in.
  3. The loop loads ALL messages for the session — including those from previous agents/models (prompt.ts:298).
  4. The most recent user message determines the active agent and model for the current turn (prompt.ts:300-336).
  5. System prompt changes to the new agent's configuration (session/llm.ts:67-93).
  6. Tools/permissions change to match the new agent (prompt.ts:602-610).
  7. The full message history is sent to the LLM — nothing is reset or truncated.

What Gets Adapted (Not Reset)

  • Provider-specific metadata is stripped from historical assistant messages when the current model differs from the message's original model (message-v2.ts:589-676). For example, Anthropic cache tokens or thinking signatures are omitted. But the actual text, tool calls, and tool results are fully preserved.
  • Agent-specific reminders are injected as ephemeral synthetic text parts when switching between "plan" and "build" agents (prompt.ts:1321-1458). These are not persisted.

Shared/Published Sessions

Sharing works via an event bus + sync system (share/share-next.ts:31-76):

  • Each new message (with its new agent/model) triggers a MessageV2.Event.Updated event
  • The share subscriber syncs the new message incrementally
  • No existing shared data is modified or removed — the share accumulates all messages from all agents/models
  • Model info is synced alongside messages

Summary

Aspect Behavior
History on agent/model change Fully preserved — all prior messages included
Provider metadata Stripped from historical messages when model differs
System prompt Changes to new agent's config
Tools/permissions Change to new agent's set
Compaction/truncation Only triggered by token overflow, never by agent/model change
Shared sessions Accumulate all messages; new ones synced incrementally
Any reset logic None exists

The design is message-centric: changing agent or model mid-session simply means the next message carries different metadata, while the entire conversation history flows through unchanged.

Can using the chat history from a different model effect how the new model interprets or responds to the prompts? Models are trained on chat contexts that they would have produced, so are not trained for optimal responses from foreign chat histories correct?

assistantFeb 22, 10:31:38 PM
claude-opus-4-6 · anthropic

You're raising a genuinely important technical point, and you're largely correct.

Cross-Model Chat History: The Problem

Yes, using chat history produced by a different model can negatively affect how a new model interprets and responds. Here's why:

Training Distribution Mismatch

Each model is fine-tuned (via RLHF, DPO, etc.) on conversations where it produced the assistant turns. The model learns to:

  1. Continue its own patterns — its particular style of reasoning, tool call formatting, and response structure
  2. Interpret context it would have generated — e.g., if Claude produces a chain-of-thought with certain markers, it knows how to build on that; GPT-4 does not
  3. Handle its own tool call/result format — different providers have different conventions for function calling, even at the message-level schema

When you swap in a foreign model's history, the new model sees assistant turns it would never have produced. This is out-of-distribution input. Concrete effects:

  • Style/tone drift: The model may struggle to maintain coherence with a predecessor's writing style
  • Reasoning chain confusion: If Model A laid out a plan in its characteristic structure, Model B may misinterpret priorities or skip steps
  • Tool call interpretation: Different models format tool calls and interpret results differently; historical tool interactions may be confusing
  • Hallucination risk: Out-of-distribution context can increase confabulation
  • Instruction following degradation: The model may be less precise in following instructions when the conversational context doesn't match its training distribution

What This Codebase Does (and Doesn't Do) About It

Looking at what we found:

  1. Provider metadata is stripped (message-v2.ts:589-676) — this removes model-specific artifacts like cache tokens and thinking signatures. That's a good start but is cosmetic, not semantic.

  2. Content is fully preserved — the actual text, tool calls, and tool results from the previous model are passed verbatim. No adaptation, rephrasing, or summarization occurs.

  3. No re-encoding or normalization layer exists between model switches.

The Severity Depends on the Switch

  • Same family, different size (e.g., Claude Sonnet → Claude Opus): Relatively safe. Similar training distribution, similar conventions.
  • Same provider, different generation (e.g., Claude 3.5 → Claude 4): Moderate risk. Style is similar but capabilities and reasoning patterns differ.
  • Cross-provider (e.g., Claude → GPT-4 → Gemini): Highest risk. Fundamentally different training data, RLHF targets, tool calling conventions, and reasoning styles.

Possible Mitigations (Not Currently Implemented)

If this is something you're considering addressing, potential approaches include:

  1. Compaction/summarization on model switch — when the model changes, summarize the prior history rather than passing it raw
  2. History attribution — inject a system-level note like "The following assistant messages were produced by a different model" so the new model can calibrate
  3. Re-encoding — pass foreign assistant turns through the new model with instructions to "restate in your own words"
  4. Hard boundary — treat a model switch as a soft session reset, carrying only a summary forward (similar to what compaction already does for token overflow)

So to directly answer your question: yes, you're correct that models are not trained to optimally continue from foreign chat histories, and this codebase currently does nothing semantic to address that mismatch beyond stripping provider-specific metadata. The full foreign history flows through as-is.

Would you like to explore designing a mitigation strategy for this? For example, triggering a compaction-like summarization on model switch, or adding attribution markers?

## ACP Session Management System -- Complete Analysis

### 1. ACP Session State

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/acp/types.ts` (lines 4-15)

```typescript
export interface ACPSessionState {
  id: string
  cwd: string
  mcpServers: McpServer[]
  createdAt: Date
  model?: {
    providerID: string
    modelID: string
  }
  variant?: string
  modeId?: string
}
```

Key observations:
- `model` is **optional** -- stored as `{ providerID, modelID }`.
- There is **no `agent` field** on `ACPSessionState`. Instead, the agent is tracked via `modeId` (which maps to an agent name).
- `variant` tracks model variant selection (e.g., "high" for extended thinking).

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/acp/session.ts` (full file, 117 lines)

The `ACPSessionManager` class provides these methods:

| Method | Lines | Purpose |
|--------|-------|---------|
| `create()` | 20-44 | Creates a new session via SDK, stores `ACPSessionState` in an in-memory `Map<string, ACPSessionState>` |
| `load()` | 46-75 | Loads an existing session via SDK, stores state |
| `get()` | 77-84 | Retrieves session or throws `RequestError.invalidParams` |
| `tryGet()` | 16-18 | Retrieves session without throwing |
| `getModel()` | 86-89 | Returns `session.model` |
| `setModel()` | 91-96 | Mutates `session.model` and re-sets in the Map |
| `getVariant()` | 98-101 | Returns `session.variant` |
| `setVariant()` | 103-108 | Mutates `session.variant` |
| `setMode()` | 110-115 | Mutates `session.modeId` (the agent) |

**There is no `setAgent()` method.** The agent is set via `setMode()` which stores `modeId` on the session state. A `grep` for `setAgent` across the entire `src/` directory returned zero results.

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/session/session.sql.ts` (89 lines)

The file defines **5 tables** via Drizzle ORM:

## 1. Keybind System

### How keybinds are defined

**Schema definition** -- `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/config/config.ts`, lines 772-924

All keybinds are declared in a Zod schema `Config.Keybinds`, a `.strict()` object where every key is a keybind name and the value is a string like `"ctrl+c,ctrl+d,<leader>q"` (comma-separated alternatives). Each has a default. Key examples:

```ts
leader: z.string().optional().default("ctrl+x")
model_list: z.string().optional().default("<leader>m")
agent_list: z.string().optional().default("<leader>a")
agent_cycle: z.string().optional().default("tab")
agent_cycle_reverse: z.string().optional().default("shift+tab")
model_cycle_recent: z.string().optional().default("f2")
command_list: z.string().optional().default("ctrl+p")
input_submit: z.string().optional().default("return")
```

User overrides go in the config file under `keybinds:` (line 1019).

### How keybind strings are parsed

**File**: `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/util/keybind.ts` (104 lines)

The `Keybind` namespace provides:
- `parse(key: string): Info[]` -- splits on `,`, then on `+`, recognizing modifiers `ctrl`, `alt`/`meta`/`option`, `shift`, `super`, `leader`, and the key name.
- `match(a, b): boolean` -- deep equality check on `{name, ctrl, meta, shift, super, leader}`.
- `fromParsedKey(key, leader)` -- converts OpenTUI's `ParsedKey` into a `Keybind.Info`.
- `toString(info)` -- renders back to human-readable `ctrl+x`.

### How keybinds are provided to the TUI

**File**: `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/cli/cmd/tui/context/keybind.tsx` (101 lines)

## 1. Database Module (`Database.use()`, `Database.transaction()`, `Database.effect()`)

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/storage/db.ts`

### Context mechanism: `AsyncLocalStorage`

The context mechanism is built on Node's `AsyncLocalStorage` via a thin wrapper:

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/util/context.ts` (lines 1-25)

```ts
import { AsyncLocalStorage } from "async_hooks"

export namespace Context {
  export class NotFound extends Error { ... }

  export function create<T>(name: string) {
    const storage = new AsyncLocalStorage<T>()
    return {
      use() {
        const result = storage.getStore()
        if (!result) throw new NotFound(name)
        return result
      },
      provide<R>(value: T, fn: () => R) {
        return storage.run(value, fn)
      },
    }
  }
}
```

The `Database` namespace creates a context that holds `{ tx: TxOrDb, effects: (() => void | Promise<void>)[] }` (db.ts, line 100-103):

```ts
const ctx = Context.create<{
  tx: TxOrDb
  effects: (() => void | Promise<void>)[]
}>("database")
```

### `Database.use()` (db.ts, lines 105-117)

```ts
export function use<T>(callback: (trx: TxOrDb) => T): T {
  try {
    return callback(ctx.use().tx)    // If context exists, reuse it (join existing tx/scope)
  } catch (err) {
    if (err instanceof Context.NotFound) {
      // No context exists: create a fresh one with the raw client (no transaction)
      const effects: (() => void | Promise<void>)[] = []
      const result = ctx.provide({ effects, tx: Client() }, () => callback(Client()))
      for (const effect of effects) effect()  // Flush effects immediately after

## 1. MessageTable Schema and the `data` Column JSON Structure

**File:** `/home/jm/data/code/opencode-trees/fr-capnweb-persistence/packages/opencode/src/session/session.sql.ts`

**Lines 8-9** define the stored type:
```ts
type PartData = Omit<MessageV2.Part, "id" | "sessionID" | "messageID">
type InfoData = Omit<MessageV2.Info, "id" | "sessionID">
```

**Lines 37-48** define the `MessageTable`:
```ts
export const MessageTable = sqliteTable(
  "message",
  {
    id: text().primaryKey(),
    session_id: text()
      .notNull()
      .references(() => SessionTable.id, { onDelete: "cascade" }),
    ...Timestamps,
    data: text({ mode: "json" }).notNull().$type<InfoData>(),
  },
  (table) => [index("message_session_idx").on(table.session_id)],
)
```

The `data` column stores `Omit<MessageV2.Info, "id" | "sessionID">` as a JSON text blob. The `id` and `sessionID` are stored as dedicated columns (`id` and `session_id`), and are reconstituted when reading (see `message-v2.ts` line 757: `{ ...row.data, id: row.id, sessionID: row.session_id }`).

Now I have all the context needed to draft a comprehensive plan. Let me put it together.


Plan: Lock Agent + Model to Session via Persistent Config

Problem

When a user switches models or agents mid-session, the entire foreign chat history is sent to the new model verbatim. Models are not trained on chat contexts produced by other models, leading to out-of-distribution input and degraded responses. There's no mechanism to bind a specific agent+model combination to a session.

Design

Add two new nullable columns to SessionTable (model and agent) that, when set, become the authoritative source for which agent and model are used for every prompt in that session. A new TUI keybind ("lock agent") writes the currently-selected agent+model from the TUI state into the session record via a new API endpoint. The prompt resolution chain reads from the session config first.

Changes by Layer

1. Schema — session.sql.ts

Add two columns to SessionTable:

model: text({ mode: "json" }).$type<{ providerID: string; modelID: string }>(),
agent: text(),

Both nullable. null means "unlocked / legacy behavior."

Generate a Drizzle migration via bun run db generate --name lock_agent_model.

2. Data Migration (backfill)

After the schema migration, add a startup backfill (not an in-migration SQL script, since it involves JSON extraction from the data column across all messages). In Database.Client initialization (after migrate()), run a one-time SQL:

UPDATE session SET
  model = (
    SELECT json_object('providerID', json_extract(m.data, '$.model.providerID'),
                        'modelID', json_extract(m.data, '$.model.modelID'))
    FROM message m
    WHERE m.session_id = session.id
      AND json_extract(m.data, '$.role') = 'user'
    ORDER BY m.time_created DESC LIMIT 1
  ),
  agent = (
    SELECT json_extract(m.data, '$.agent')
    FROM message m
    WHERE m.session_id = session.id
      AND json_extract(m.data, '$.role') = 'user'
    ORDER BY m.time_created DESC LIMIT 1
  )
WHERE session.model IS NULL

Guard with a flag (e.g., check if any session already has a non-null model) to avoid re-running.

3. Session Info Type — session/index.ts

  • Add to Session.Info Zod schema:
    model: z.object({ providerID: z.string(), modelID: z.string() }).optional(),
    agent: z.string().optional(),
    
  • Update fromRow() and toRow() to map the new columns.
  • Add a new setter: Session.setModelAgent(sessionID, model, agent) following the same pattern as setPermission() — a Database.use() block that updates, publishes Event.Updated.

4. Session Route — server/routes/session.ts

Add a new endpoint:

PATCH /:sessionID/config
Body: { model: { providerID, modelID }, agent: string }

Calls Session.setModelAgent(). This is what the TUI "lock agent" keybind will hit.

Alternatively, extend the existing PATCH /:sessionID route to accept model and agent fields alongside title and time.archived.

5. Prompt Resolution — session/prompt.ts

createUserMessage() (line 954-978): Change the resolution chain:

// Current:
const agent = await Agent.get(input.agent ?? (await Agent.defaultAgent()))
const model = input.model ?? agent.model ?? (await lastModel(input.sessionID))

// New:
const session = await Session.get(input.sessionID)
const agentName = session.agent ?? input.agent ?? (await Agent.defaultAgent())
const agent = await Agent.get(agentName)
const model = session.model ?? input.model ?? agent.model ?? (await lastModel(input.sessionID))

Session config takes priority. The resolved values are still stored on the user message for provenance.

Apply the same change to the shell command path (shellMessage() around line 1497) and any other prompt entry points.

6. TUI Keybind — Config + Registration

config/config.ts: Add to Config.Keybinds:

lock_agent: z.string().optional().default("<leader>l").describe("Lock agent and model to session"),

cli/cmd/tui/app.tsx: Register a command:

command.register(() => [{
  title: "Lock Agent to Session",
  value: "session.lock_agent",
  keybind: "lock_agent",
  category: "Session",
  onSelect: async () => {
    const model = local.model.current()
    const agent = local.agent.current()
    if (!model || !session) return
    await sdk.client.session.config({
      sessionID: session.id,
      model: { providerID: model.providerID, modelID: model.modelID },
      agent: agent.name,
    })
  },
}])

7. TUI State Feedback

When a session has a locked agent+model, the TUI should:

  • Read the session's model and agent fields from the synced session data
  • Visually indicate the lock state (e.g., a lock icon or different color on the model/agent display)
  • Optionally: when a locked session is active, disable or grey out the model/agent selectors (or show a warning that changing requires "lock agent" to persist)

8. Share Sync

No changes needed to share-next.ts. The existing Session.Event.Updated subscriber sends the full SDK.Session object. As long as the SDK types include the new model and agent fields, shares will sync them automatically.

9. SDK Types

Update the SDK's Session type to include the new optional model and agent fields so they appear in the API response and share sync payloads.

User has answered your questions: "When a session has a locked agent+model, should the TUI model/agent selectors still be usable (with changes only persisting when 'lock agent' is pressed again), or should they be disabled for locked sessions?"="Selectors stay usable", "Should unlocking (removing the lock) be supported, and if so how?"="No unlock needed", "For the backfill migration — the plan proposes extracting the last user message's model/agent for each existing session. But this means ALL existing sessions become 'locked'. Is that the intent, or should existing sessions remain unlocked and only get locked when the user explicitly uses the new keybind?"="Don't backfill, lock on next use". You can now continue with the user's answers in mind.

Good, that simplifies things significantly. No backfill migration, no unlock mechanism. Let me finalize the plan.


Final Plan: Lock Agent + Model to Session

Summary

Add persistent model (JSON) and agent (text) columns to the session table. When set (non-null), they override all per-message model/agent resolution. A new TUI keybind <leader>l ("Lock Agent") writes the TUI's current agent+model selection to the session record via a new API endpoint. Existing sessions remain unlocked (null) and only get locked when the user explicitly invokes the keybind. Selectors remain usable — only pressing "Lock Agent" persists the change.

Implementation Steps

Step 1 — Schema (packages/opencode/src/session/session.sql.ts)

  • Add to SessionTable:
    model: text({ mode: "json" }).$type<{ providerID: string; modelID: string }>(),
    agent: text(),
    
  • Run bun run db generate --name lock_agent_model to produce the migration SQL.

Step 2 — Session Info Type (packages/opencode/src/session/index.ts)

  • Add to Session.Info Zod schema:
    model: z.object({ providerID: z.string(), modelID: z.string() }).optional(),
    agent: z.string().optional(),
    
  • Update fromRow(): map row.model ?? undefined and row.agent ?? undefined.
  • Update toRow(): map info.model ?? null and info.agent ?? null.
  • Add Session.setModelAgent(sessionID, model, agent) setter following the setPermission() pattern — Database.use()db.update()fromRow()Bus.publish(Event.Updated).

Step 3 — API Route (packages/opencode/src/server/routes/session.ts)

  • Extend the existing PATCH /:sessionID route to accept optional model and agent fields alongside title and time.archived. When present, call Session.setModelAgent().

Step 4 — Prompt Resolution (packages/opencode/src/session/prompt.ts)

  • In createUserMessage() (~line 954): load the session, and if session.model / session.agent are set, use them as the highest-priority source:
    const session = await Session.get(input.sessionID)
    const agentName = session.agent ?? input.agent ?? (await Agent.defaultAgent())
    const agent = await Agent.get(agentName)
    const model = session.model ?? input.model ?? agent.model ?? (await lastModel(input.sessionID))
    
  • Apply the same priority change to the shell message path (~line 1497).
  • The resolved values are still stored on the user message for provenance (no change to message schema).

Step 5 — Keybind Config (packages/opencode/src/config/config.ts)

  • Add to Config.Keybinds:
    lock_agent: z.string().optional().default("<leader>l").describe("Lock agent and model to session"),
    

Step 6 — TUI Command Registration (packages/opencode/src/cli/cmd/tui/app.tsx)

  • Register a new command:
    {
      title: "Lock Agent to Session",
      value: "session.lock_agent",
      keybind: "lock_agent",
      category: "Session",
      onSelect: async () => {
        const model = local.model.current()
        const agent = local.agent.current()
        const sessionID = /* current session ID */
        if (!model || !sessionID) return
        await sdk.client.session.update(sessionID, {
          model: { providerID: model.providerID, modelID: model.modelID },
          agent: agent.name,
        })
      },
    }
    
  • Model/agent selectors remain fully usable. Only pressing <leader>l persists the selection to the session.

Step 7 — TUI Visual Indicator (optional, in header/status bar component)

  • When the active session has non-null model/agent, display a visual cue (e.g., lock icon or "(locked)" suffix next to the model/agent name) so the user knows the session has a pinned config.

Step 8 — SDK Types (if SDK package has separate type definitions)

  • Add model?: { providerID: string; modelID: string } and agent?: string to the SDK's Session type so the fields appear in API responses and share sync payloads.

What Stays the Same

  • Message-level tracking: Each message still records its agent+model for provenance.
  • Share sync: Session.Event.Updated already sends the full session object — new fields sync automatically.
  • Compaction: Unaffected; still triggers only on token overflow.
  • Existing sessions: Stay unlocked (null). The per-message resolution chain is the fallback when session-level config is null.
  • ACP layer: Unaffected; it passes model/agent explicitly, which would be overridden by session config if locked.

packages/opencode/src/session/index.ts Info schema, fromRow, toRow, setModelAgent
packages/opencode/src/session/prompt.ts Resolution priority in createUserMessage + shell

packages/opencode/src/config/config.ts Add lock_agent keybind
packages/opencode/src/cli/cmd/tui/app.tsx Register lock-agent command
SDK type definitions (if separate) Add optional fields

Risk Assessment

  • Low risk: Schema change is additive (nullable columns). No existing behavior changes unless user explicitly locks.
  • Fallback is safe: null session model/agent falls through to existing per-message resolution.
  • No data migration needed: Existing sessions are unaffected.

Shall I proceed with implementation?

The changes visible are from pre-existing work on the branch, not from our implementation. The advanced-coding-manager didn't execute. Let me implement this directly using coding agents in parallel.

Now let me see how sdk.client.session.update is called (the rename dialog gives us the pattern):

Good, I can see the SDK call pattern: sdk.client.session.update({ sessionID, title }). Now I have everything I need. Note that <leader>l is already taken by session_list. Let me pick a different default. Let me also check the prompt.ts imports and the shell path more carefully.

Now I have all the context. Let me implement the changes. I'll start with the schema, session index, and config changes in parallel since they're independent.

Two issues to fix:

  1. The keybind name needs to match the generated type from the config. Let me check what the SDK client type expects.
  2. The SDK client type needs to be regenerated or we need to check how the SDK types are generated.

The SDK is auto-generated and needs to be regenerated. The SDK types don't include locked yet. I need to regenerate the SDK. Let me check how to do that:

The SDK generation requires running bun dev generate which starts the server to generate OpenAPI spec. This is a complex process. For now, the practical approach is to update the SDK types manually, or use a type assertion in the TUI code. Since the SDK is auto-generated and regenerating requires a running server, let me take the pragmatic approach of updating the generated SDK types to include the locked field, and use the proper typing in the TUI.

I need to update 3 things in the generated SDK types:

  1. Add locked to Session type
  2. Add locked to SessionUpdateData.body
  3. Add locked to the SDK's session.update() method parameters and args

Let me also check the sdk.gen.ts for the session.update args builder:

The batch edits caused multiple applications (duplications) because the batch ran all 3 in parallel but the types.gen.ts edits matched multiple times. Let me look at the current state and fix:

The locked fields were added to the PTY update method (line 579) instead of being applied only to the session update method (line 653). The PTY update at line 579 should NOT have locked. Let me fix both — remove the extra PTY update method's locked field, and remove the duplicate session update method:
