Bug Sweep & Architectural Review (Critical Findings) +## 2. Bug Sweep & Architectural Review (Critical Findings Resolved) -During our end-of-day audit, we challenged our assumptions and swept the new -code. We discovered two critical logic flaws that must be addressed first thing -tomorrow: +Both critical flaws discovered on Day 1 have been completely resolved: -### 🚨 Bug 1: The "Duplicate Projection" Flaw (N-to-1 Variant Targeting) +### ✅ Resolved Bug 1: The "Duplicate Projection" Flaw (N-to-1 Variant Targeting) +**The Fix:** The `getWorkingBufferView()` method tracks a `skippedIds` Set during its sweep. If it chooses a SnapshotVariant, it pushes all `replacedEpisodeIds` into the Set, cleanly skipping the raw text nodes on subsequent iterations. -**The Flaw:** In `StateSnapshotWorker`, we synthesize `N` episodes (e.g., -Episodes 1, 2, 3) into a single `SnapshotVariant`. We currently attach this -variant _only_ to the newest episode in the batch (Episode 3) via `targetId`. -When the Opportunistic Swapper loops backwards (`i = 3, 2, 1`), it hits Episode -3, sees the Snapshot, and injects it. But then the loop continues to Episode 2 -and Episode 1! Since they don't have the variant attached, the swapper injects -them as **raw text**. The final projection contains _both_ the snapshot AND the -raw text it was supposed to replace. **The Fix (The Working Buffer -Architecture):** Instead of projecting variants on the fly during a backwards -sweep, the `ContextManager` will maintain two separate graphs: an immutable -`pristineLog` (for future offloading to the Memory Wheel) and a mutable -`workingContext`. When the `StateSnapshotWorker` finishes, it structurally -_replaces_ the N raw episodes with the 1 Snapshot episode directly in the -`workingContext` array. This eliminates the duplicate projection bug entirely. - -### 🚨 Bug 2: Infinite RAM Growth (Pristine Graph Accumulation) - -**The Flaw:** Async variants only replace text in the _Projected_ graph. The -_Pristine_ graph inside `ContextManager` (`this.pristineEpisodes`) never -shrinks. Because `checkTriggers()` calculates tokens based on the pristine -graph, once the history crosses `retainedTokens` (65k), it will _always_ be over -65k, emitting `BUDGET_RETAINED_CROSSED` on every single turn forever. -Furthermore, if we never delete episodes from the pristine graph, the Node.js -process will eventually run out of heap memory (OOM) on extremely long sessions. -**The Fix (The Working Buffer Architecture):** By calculating the token budget -against the mutable `workingContext` (which is actively compacted by background -snapshots) rather than the immutable `pristineLog`, the token count will -successfully drop back below `retainedTokens` (65k). This breaks the infinite -event loop and prevents OOM crashes. The `pristineLog` will just grow until the -future Memory Subsystem is built to page it to disk. - -### 🚨 Minor Risk: Identity Map Mutation - -**The Risk:** `IrMapper` relies on `WeakMap`. If the user uses -a UI command to _edit_ a previous message, `AgentChatHistory` might replace the -`Content` object reference. This would generate a new UUID, instantly orphaning -any background variants currently computing for the old reference. **The -Mitigation:** We must ensure `ContextManager` handles orphaned `VARIANT_READY` -events gracefully (e.g., if `targetId` is not found, simply discard the variant -and log a debug warning). (I verified we already wrote `if (targetEp)` checks in -`ContextManager`, so this is mitigated). +### ✅ Resolved Bug 2: Infinite RAM Growth (Pristine Graph Accumulation) +**The Fix:** The `checkTriggers()` method now calculates its token budget against the computed `WorkingBufferView` rather than the `pristineEpisodes` array. As soon as an async worker injects a snapshot, the calculated token count plummets natively, breaking the infinite GC loop while leaving the pristine log untouched. diff --git a/packages/core/src/context/contextManager.async.test.ts b/packages/core/src/context/contextManager.async.test.ts new file mode 100644 index 0000000000..6f14104f1b --- /dev/null +++ b/packages/core/src/context/contextManager.async.test.ts @@ -0,0 +1,131 @@ +/** + * @license + * Copyright 2026 Google LLC + * SPDX-License-Identifier: Apache-2.0 + */ + +import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest'; +import { + createSyntheticHistory, + createMockContextConfig, + setupContextComponentTest, +} from './testing/contextTestUtils.js'; + +describe('ContextManager Concurrency Component Tests', () => { + beforeEach(() => { + vi.useFakeTimers(); + }); + + afterEach(() => { + vi.useRealTimers(); + vi.restoreAllMocks(); + }); + + it('should asynchronously compress history when retainedTokens is crossed, without blocking projection', async () => { + // 1.

Whenever we want to answer the question, "What exact JSON/Content array will the Gemini API receive?", we use a golden test. +2. **Component Tests:** Used to verify *logic, system invariants, and concurrency*. These tests instantiate multiple classes (e.g., `ContextManager` + `AgentChatHistory` + `Workers`) and use mocks for the network (LLM) and timers. This is our primary defense against race conditions. +3. **Unit Tests:** Used to verify *isolated, complex algorithms* and *corner cases*. If a method involves math, string manipulation, or complex isolated logic (like iterating and skipping nodes), it gets a unit test. + +--- + +## 1. ContextManager (The Orchestrator) + +The `ContextManager` sits at the center, maintaining the View and enforcing the Synchronous Pressure Barrier. + +### Component Tests +* **[COMPLETED] Race Condition: User Typing:** The user pushes new history while a background snapshot is computing. Ensure the snapshot is applied to older nodes, but the new nodes are preserved at the tail. +* **[COMPLETED] Async GC Trigger:** Pushing history past `retainedTokens` triggers the `StateSnapshotWorker` without blocking the main thread. +* **Sync Barrier - Truncate Strategy:** If history is pushed past `maxTokens` (e.g., pasting a massive file) and `maxPressureStrategy = 'truncate'`, the `projectCompressedHistory` method must instantly drop the oldest unprotected episodes until the budget is satisfied. +* **Sync Barrier - Compress Strategy:** If history is pushed past `maxTokens` and strategy is `compress`, it blocks and falls back (or synchronously calls the worker). +* **Protection Boundaries:** Ensure the System Prompt (Episode 0) and the Latest Turn (working context) are never dropped or heavily compressed, even under severe max token pressure. + +### Unit Tests +* **The View Generator Sweep (`getWorkingBufferView`):** + * Test N-to-1 Replacement: If a snapshot covers IDs `[A, B, C]`, ensure all three are completely omitted from the resulting array and replaced by the single snapshot node. + * Test Priority: If an episode has both a `snapshot` and a `summary` variant ready, ensure `snapshot` wins. + +--- + +## 2. IrMapper (The Translation Layer) + +The `IrMapper` translates flat `Content[]` arrays into the pristine `Episode[]` graph, and vice-versa. + +### Golden Tests +* **Multi-turn Flattening:** Ensure that `prompt -> thought -> toolCall -> toolResponse -> thought -> yield` translates back into a perfectly ordered `Content[]` array that the Gemini API accepts. + +### Unit Tests +* **WeakMap Node Pinning (ID Stability):** Call `toIr(history)` -> get Episode IDs. Push one more message to history. Call `toIr(history)` again. Assert that the IDs of the older episodes are identical (proving the `WeakMap` successfully pinned the reference). This is critical; if this fails, async variants will orphan. +* **Token Estimation Integration:** Verify that `metadata.currentTokens` and `metadata.originalTokens` are populated accurately during mapping. + +--- + +## 3. Async Workers (The Subconscious) + +Workers listen to the Event Bus, do heavy LLM lifting, and emit ready variants. + +### Component Tests +* **StateSnapshotWorker Batching:** When triggered, it should gather the *oldest unprotected* episodes. It must stop gathering once `tokensToSynthesize >= targetDeficit`. +* **StateSnapshotWorker Telemetry & Role:** Ensure the API call is dispatched using the `gemini-2.5-flash` model and the `LlmRole.UTILITY_COMPRESSOR` role. +* **(Future) AsyncSemanticCompressor:** Testing the eager-compute summarization of large files. + +--- + +## 4. Sync Processors (The Fallback / Bloom Filter) + +Processors execute synchronously during `projectCompressedHistory` if the background workers haven't caught up, or to squash tokens down to the `retainedTokens` floor. + +### Unit Tests +* **HistorySquashingProcessor:** Test proportional truncation math. If an episode is 10k tokens and the budget demands saving 5k tokens, ensure the text is sliced cleanly without breaking formatting. +* **ToolMaskingProcessor:** Verify the leaf-node deep JSON truncation logic. Ensure deeply nested massive arrays are masked (`"[1000 items hidden]"`), but the outer schema remains valid JSON. +* **SemanticCompressionProcessor:** Verify it skips episodes that already have `summary` variants in the View. + +### Golden Tests +* **Masked Output Shapes:** Verify the visual presentation of a squashed or masked node (e.g., ensuring `[System: Truncated...]` headers are formatted nicely). diff --git a/packages/core/src/context/testing/contextTestUtils.ts b/packages/core/src/context/testing/contextTestUtils.ts new file mode 100644 index 0000000000..d84c0d3cc1 --- /dev/null +++ b/packages/core/src/context/testing/contextTestUtils.ts @@ -0,0 +1,97 @@ +/** + * @license + * Copyright 2026 Google LLC + * SPDX-License-Identifier: Apache-2.0 + */ + +import { vi } from 'vitest'; +import type { Config } from '../../config/config.js'; +import type { GeminiClient } from '../../core/client.js'; +import type { Content } from '@google/genai'; +import { AgentChatHistory } from '../../core/agentChatHistory.js'; +import { ContextManager } from '../contextManager.js'; + +/** + * Creates a block of synthetic conversation history designed to consume a specific number of tokens. + * Assumes roughly 4 characters per token for standard English text. + */ +export function createSyntheticHistory( + numTurns: number, + tokensPerTurn: number, +): Content[] { + const history: Content[] = []; + const charsPerTurn = tokensPerTurn * 4; + + for (let i = 0; i < numTurns; i++) { + history.push({ + role: 'user', + parts: [{ text: `User turn ${i}. ` + 'A'.repeat(charsPerTurn) }], + }); + history.push({ + role: 'model', + parts: [{ text: `Model response ${i}. ` + 'B'.repeat(charsPerTurn) }], + }); + } + + return history; +} + +/** + * Creates a fully mocked Config object tailored for Context Component testing. + */ +export function createMockContextConfig( + overrides?: Record, + llmClientOverride?: unknown, +): Config { + const defaultConfig = { + isContextManagementEnabled: vi.fn().mockReturnValue(true), + getContextManagementConfig: vi.fn().mockReturnValue({ + enabled: true, + strategies: { + historySquashing: { maxTokensPerNode: 3000 }, + toolMasking: { stringLengthThresholdTokens: 10000 }, + semanticCompression: { + nodeThresholdTokens: 5000, + compressionModel: 'gemini-2.5-flash', + }, + }, + budget: { + maxTokens: 150000, + retainedTokens: 65000, + protectedEpisodes: 1, + protectSystemEpisode: true, + maxPressureStrategy: 'truncate', + }, + }), + getBaseLlmClient: vi.fn().mockReturnValue( + llmClientOverride || { + generateContent: vi.fn().mockResolvedValue({ + text: 'Synthesized state', + }), + }, + ), + getUsageStatisticsEnabled: vi.fn().mockReturnValue(false), + getTargetDir: vi.fn().mockReturnValue('/tmp'), + getSessionId: vi.fn().mockReturnValue('test-session'), + }; + + return { ...defaultConfig, ...overrides } as unknown as Config; +} + +/** + * Wires up a full ContextManager component with an AgentChatHistory and active background workers. + */ +export function setupContextComponentTest(config: Config) { + const chatHistory = new AgentChatHistory(); + const contextManager = new ContextManager( + config, + config.getBaseLlmClient() as unknown as GeminiClient, + ); + + // The async worker is now internally managed by ContextManager + + // Subscribe to history to enable the Eager/Opportunistic triggers + contextManager.subscribeToHistory(chatHistory); + + return { chatHistory, contextManager }; +} diff --git a/packages/core/src/context/tracer.ts b/packages/core/src/context/tracer.ts new file mode 100644 index 0000000000..542f0ee45c --- /dev/null +++ b/packages/core/src/context/tracer.ts @@ -0,0 +1,58 @@ +/** + * @license + * Copyright 2026 Google LLC + * SPDX-License-Identifier: Apache-2.0 + */ + +import * as fs from 'node:fs'; +import * as path from 'node:path'; +import { randomUUID } from 'node:crypto'; + +export class ContextTracer { + private traceDir: string; + private assetsDir: string; + private enabled: boolean; + + constructor(targetDir: string, sessionId: string) { + this.enabled = process.env['GEMINI_CONTEXT_TRACE'] === 'true'; + this.traceDir = path.join(targetDir, '.gemini', 'context_trace', sessionId); + this.assetsDir = path.join(this.traceDir, 'assets'); + + if (this.enabled) { + try { + fs.mkdirSync(this.assetsDir, { recursive: true }); + this.logEvent('SYSTEM', 'Context Tracer Initialized', { sessionId }); + } catch (e) { + console.error('Failed to initialize ContextTracer', e); + this.enabled = false; + } + } + } + + logEvent(component: string, action: string, details?: Record) { + if (!this.enabled) return; + try { + const timestamp = new Date().toISOString(); + const detailsStr = details ?
