将源代码输入传递给 AST 分析的流程

编写日期：2026 年 6 月 26 日

目的

本文档用于补充 docs/roadmaps/2026-06-25-source-analysis-scoring-architecture.md 的前置部分。

在基准路线图中已经整理了以下流程。

project source
  -> AST chunks or direct chunks
  -> official docs JSONL retrieval
  -> on-demand LLM verification
  -> score DB
  -> classified filesystem

这里整理了当用户提供提示词和源代码时，如何将这些输入以何种形式传递给 AST Parser。

核心原则

提示词和源代码虽然属于同一输入集合，但作用不同。

输入	作用
用户提示词	分析意图、问题类型、期望输出方向
源代码	AST Parser 实际要解析的对象
文件路径/项目信息	用于识别分析单元、进行项目级别分类的元数据

AST Parser 解析源代码。提示词并不是 AST 语法分析的对象。

不过提示词会在后续阶段用于决定先查看哪些片段、使用哪个 Retriever、以及在 Qwen 3.6 中生成何种验证请求。

输入包

用户输入首先被汇总为一个分析请求。

analysis_request
  prompt
  source
  source_kind
  project_id
  source_file
  source_sha256
  source_origin

各项的含义如下。

项目	说明
`prompt`	用户输入的问题。例如：“这段代码是什么意思？”， “需要转换为 Godot 4 吗？”
`source`	原始源码文本。尽可能原样保留。
`source_kind`	`gdscript`、`scene`、`resource`、`project_config`、`markdown`、`unknown` 等输入类型
`project_id`	用于区分 GitHub 仓库或本地项目的 ID
`source_file`	项目内的文件路径。如果是单个代码粘贴，则使用临时路径。
`source_sha256`	原始源码文本的哈希值。粘贴和文件输入都会在请求创建时计算。
`source_origin`	`github`、`local_directory`、`uploaded_file`、`pasted_snippet` 等来源

在此阶段不确定输出 JSONL 架构或 score DB 列。目的是让 AST Parser 与后续 Retriever/LLM 步骤能够以相同的基准追踪相同的输入。

单个源码粘贴

用户在 Web UI 或 CLI 中直接输入提示词和源码的情况。

示例：

需要将此转换为 Godot 4 吗？
extends KinematicBody2D

func _physics_process(delta):
    move_and_slide()

处理流程：

将输入包装为 analysis_request。
source_origin 设为 pasted_snippet。
由于没有实际文件路径，source_file 使用类似 pasted://snippet-<id>.gd 的临时标识符。
source_sha256 根据粘贴的原始代码立即计算。
source_kind 根据扩展名提示、代码内容、用户指定的语言进行推断。
将 source、source_kind、source_file、source_sha256 传递给 AST Parser。
将 Prompt 保存在 analysis_request.prompt 中，不与 Parser 混用。

项目目录输入

用于分析 GitHub 仓库或本地文件夹的情况。

处理流程：

将项目根目录包装为 project_id。
按相对路径遍历文件系统。
首先记录每个文件的包含/排除状态。
将被排除的文件以 excluded_files 形式保留，以便在 Web UI 或日志中查看。
将被包含的文件展开为带有 # <relative/path> 标题的纯文本块。
.gd 文件交给 AST Parser，按原始顺序生成函数/代码片段。
对非 AST Parser 目标的包含文件，应用适合文件特性的直接碎片化规则。
每个碎片携带原始路径、原始顺序、哈希后传递给 Retriever 请求。

初始目标文件与基准路线图相同。

文件	AST/碎片化方向
`.gd`	GDScript AST，函数，类，signal，变量，API 调用候选
`.tscn`	场景节点类型，脚本引用，资源引用，导出属性
`.tres`	资源类型，脚本类，material/shader/resource 线索
`project.godot`	Godot 版本提示，autoload，renderer，feature，input map
README/文档	基本上在源码 AST 分析中排除。将排除与否及原因记录在 UI/日志中。

项目源码纯文本展开

项目级输入首先展开为按文件分组的纯文本块。该纯文本不是直接一次性放入 LLM 的最终 Prompt，而是为保持文件边界和相对路径而使用的中间表示。

基本形式：

# project.godot
; original project.godot content

# scripts/player.gd
extends KinematicBody2D

func _physics_process(delta):
    move_and_slide(velocity)

# scenes/player.tscn
[gd_scene load_steps=2 format=3]
[node name="Player" type="CharacterBody2D"]

规则：

文件头部使用 # <relative/path> 形式。
相对路径以项目根目录为基准。
文件正文尽可能保持原文不变。
此纯文本块用于文件边界确认和调试。
实际处理时不会一次性将整个纯文本块交给 LLM 或 AST 解析器。
通过标题划分的每个文件首先接受包含/排除判定。
被排除的文件记录在 excluded_files 中。
被包含的 .gd 文件会经过 analysis_request 后进入 AST 解析器。
被包含的非 .gd 文本/配置文件直接交给分块器处理。

这样既能保留用户提供的“整个项目源码”供人阅读，又能在后续阶段按文件/分块追踪排除文件、AST 分块、直接分块、Retriever 负载等信息。

克隆项目基准确认计划

仅凭抽象示例难以确认 AST 解析器向 Retriever 传递的流程。因此，需要克隆一个实际的 Godot 项目，并以该项目的文件树、纯文本展开、AST 分块/直接分块划分、Retriever 请求循环等为基准进行确认。

基准项目设置如下。

项目	值
仓库	`godotengine/godot-demo-projects`
项目路径	`2d/dodge_the_creeps`
选择原因	是 Godot 官方演示项目，包含 `.gd`、`.tscn`、`project.godot`、README、资源引用等，可小范围验证项目输入流程。
保存基准	克隆的源码不提交到仓库，仅在文档中保留树结构和处理计划。

克隆基准：

git clone --depth 1 --filter=blob:none --sparse https://github.com/godotengine/godot-demo-projects.git /tmp/idea_world_godot_demo_projects
cd /tmp/idea_world_godot_demo_projects
git sparse-checkout set 2d/dodge_the_creeps

此克隆用于流程确认。不会复制仓库中克隆的项目源代码或资源。

确认对象是克隆项目的全部文件路径。首先按排序顺序展开所有路径，并将每个文件划分为 LLM 可读取的片段。此处不创建额外的中间数据库。关键不是“一次性读取整个仓库”，而是“按路径顺序创建片段，并对每个片段多次调用”。

文件碎片化标准：

文件类型	碎片化方式	后续调用方式
`.gd`	AST Parser 按原始顺序生成函数、signal、变量、class extends、API 调用碎片。	对每个 AST 碎片调用 Retriever，并将 `提示词 + AST 碎片 + 检索结果` 发送给 LLM。
`project.godot`	不放入 AST Parser。若为包含对象，则生成 section/key-value、主场景、特性、input map 碎片。	直接将碎片发送给 Retriever，或作为 `.gd` AST 判断的周边上下文附加。
`.tscn`, `.tres`	不放入 AST Parser。若为包含对象，则生成 node block、ext_resource、sub_resource、connection 碎片。	直接将碎片发送给 Retriever，或作为关联的 `.gd` 文件的 AST 判断的周边上下文附加。
`.md`, `.txt`, `LICENSE`	在源码 AST 分析中默认排除。	将排除与否及原因记录在 UI/日志中。若不是单独的文档分析模式，则不发送给 Retriever。
`.import`, `.uid`, `.gitignore`, `.gdignore`	不放入 AST Parser。若为包含对象，则生成行或 key-value 碎片。	直接将碎片发送给 Retriever，或仅用作文件路径/资源关系的周边上下文。
图片、音频、字体等二进制文件	同样不放入 AST Parser，也不将原始 bytes 放入 LLM。仅保留路径和排除原因。	当该路径出现在 `.tscn`、`.import` 等文本碎片中时，仅作为关联信息使用。

即进入 AST Parser 的对象是 .gd 文件。整个仓库按路径顺序展开，但结果并不是“一次性发送给 LLM 的大正文”。# <relative/path> 标题用于标记文件来源路径，以及随后被拆分为哪些函数/代码/设置碎片并进入 Retriever。像 .md 这类被排除的文件会记录在排除列表中，包含的 .gd 文件则由 AST Parser 按函数或代码碎片顺序拆分。随后对 LLM 的调用始终以 提示词 + 当前碎片 + Retriever 检索结果 的形式多次执行。

for each file in repository path order:
  record file path under "# <relative/path>"
  if file is excluded by source-analysis policy:
    save excluded_files entry with reason
    continue
  if file.path endswith ".gd":
    ast_chunks = ast_parse(full_file_text)
    for each ast_chunk in ast_chunks:
      retrieved = retrieve(build_query_from_chunk(prompt, ast_chunk))
      response = call_llm(prompt + ast_chunk + retrieved)
      validate(response)
      save_chunk_result(response)
  else:
    text_chunks = split_without_ast(file)
    for each text_chunk in text_chunks:
      retrieved = retrieve(build_query_from_chunk(prompt, text_chunk))
      response = call_llm(prompt + text_chunk + retrieved)
      validate(response)
      save_chunk_result(response)

最终的 LLM 输入单元始终是以下形式。

llm_judgment_request
  user_prompt
  project_id
  source_file
  chunk_id
  chunk_order
  chunk_kind
  chunk_text
  retrieved_evidence

Retriever 搜索输入

Retriever 只负责在数据库中搜索我提供的代码片段。文件路径、chunk id、chunk order 不是搜索条件，而是追踪信息。因此在实现中将这两个对象分离。

chunk_trace
  project_id
  source_file
  source_sha256
  chunk_id
  chunk_order
  chunk_kind

retriever_query
  query_text
  query_terms
  raw_chunk_text
  symbol_candidates
  api_call_candidates
  reference_candidates
  prompt_terms

chunk_trace仅用于 UI、日志、重启、调试、LLM 响应连接。Retriever 搜索函数只传递 retriever_query。

AST/direct chunk
  -> build_retriever_query(chunk_text, extracted_candidates, user_prompt)
  -> retriever.search(retriever_query)
  -> orchestrator attaches chunk_trace to returned hits
  -> prompt + chunk_text + retrieved_hits -> LLM judgment

即搜索使用以下值。

使用于搜索	不用于搜索
`chunk_text`	`source_file`
`symbol_candidates`	`chunk_id`
`api_call_candidates`	`chunk_order`
`reference_candidates`	`source_sha256`
`prompt_terms`	`project_id`

需要文件路径的原因是追踪，而不是搜索。例如，需要有 player.gd:function:_process 这样的 trace，才能在网页 UI 中显示 “此响应来自 player.gd 的第四段”。但当 Retriever 在数据库中查找依据时，需要搜索的不是 player.gd 路径，而是 _process 函数内部的代码和 API 候选项。

例如，player.gd 的 _process 函数片段首先会将追踪信息和搜索信息分离。

chunk_trace
  project_id: "github:godotengine/godot-demo-projects/2d/dodge_the_creeps"
  source_file: "player.gd"
  source_sha256: "87f4fcf7481dba031f74a363475cee75b81c3d42eb1347b318f6b824e37329a6"

    	if Input.is_action_pressed(&"move_left"):

    		rotation = PI if velocity.y > 0 else 0

Retriever 检索代码标准

    }

在上述代码中，重要点如下。

Retriever 检索函数不接受 source_file、chunk_id、chunk_order 作为检索条件。
Retriever 使用代码片段中生成的 query_embedding 进行向量搜索，query.query_text 用于关键字/三元组的辅助检索。
query_embedding 由 raw_chunk_text、API 候选、符号候选、提示意图词组合而成。
query.query_text 由文件内部代码片段中提取的 API、符号、标识符、提示意图词构成。
文件路径和 chunk 顺序仅保留在 ChunkTrace 中。
retrieve_with_trace 是在检索后将结果与 trace 捆绑的 orchestrator 函数，实际检索由 retrieve_for_query 完成。
docs_chunks、api_mapping、label_prototypes 使用相同的 RetrieverQuery 进行检索。

godot_rag.dynamic_retrieval_view 并非新的判断逻辑，而是用于检索的平坦化视图。即使三个表的 payload 结构不同，Retriever 也会看到相同的列。

dynamic_retrieval_view
  table_name
  id
  title
  content
  embedding
  search_text
  search_tsv
  metadata

搜索目标展开如下。这里仍然将 source_file、source_url 等来源字段保留在 metadata 中，但不放入默认搜索字符串。搜索应基于代码片段的 API/符号/模式进行。

表格	`title`	`content`	`search_text` 中的值
`docs_chunks`	文档标题、section 路径、symbol	文档正文块	`doc_type`、`symbol`、`section_path`、`content`、`api_symbols`
`api_mapping`	已更改的 API 或旧 API 名称	迁移说明、变更原因、示例	`old_symbol`、`new_symbol`、`change_type`、`description`、`before_code`、`after_code`
`label_prototypes`	prototype 名称或标签	函数使用方式、参数构成、调用模式变更示例	`label`、`input_pattern`、`prompt_pattern`、`before_code`、`after_code`、`expected_response`、`explanation`

示例 SQL 视图形式：

create or replace view godot_rag.dynamic_retrieval_view as
select
  'docs_chunks' as table_name,
  id,
  coalesce(payload->>'title', payload->>'symbol', source_file) as title,
  coalesce(payload->>'content', '') as content,
  embedding,
  concat_ws(
    ' ',
    payload->>'doc_type',
    payload->>'symbol',
    payload->>'section_path',
    payload->>'content',
    payload->>'api_symbols'
  ) as search_text,
  search_tsv,
  payload || jsonb_build_object('source_file', source_file, 'source_url', payload->>'source_url') as metadata
from godot_rag.docs_chunks
union all
select
  'api_mapping' as table_name,
  id,
  concat_ws(' -> ', payload->>'old_symbol', payload->>'new_symbol') as title,
  concat_ws(' ', payload->>'description', payload->>'rationale') as content,
  embedding,
  concat_ws(
    ' ',
    payload->>'old_symbol',
    payload->>'new_symbol',
    payload->>'change_type',
    payload->>'description',
    payload->>'before_code',
    payload->>'after_code'
  ) as search_text,
  search_tsv,
  payload || jsonb_build_object('source_file', source_file, 'source_url', payload->>'source_url') as metadata
from godot_rag.api_mapping
union all
select
  'label_prototypes' as table_name,
  id,
  coalesce(payload->>'label', payload->>'name', source_file) as title,
  concat_ws(' ', payload->>'expected_response', payload->>'explanation') as content,
  embedding,
  concat_ws(
    ' ',
    payload->>'label',
    payload->>'input_pattern',
    payload->>'prompt_pattern',
    payload->>'before_code',
    payload->>'after_code',
    payload->>'expected_response',
    payload->>'explanation'
  ) as search_text,
  search_tsv,
  payload || jsonb_build_object('source_file', source_file) as metadata
from godot_rag.label_prototypes;

在此视图上，Retriever 实际检索的值是 query_text。例如，如果是 _process 块，则如下检索。

query_text =
  "Input.is_action_pressed Vector2.ZERO velocity.normalized position.clamp Vector2 AnimatedSprite2D _process Godot 3 Godot 4 migration"

搜索结果不是可以直接信任并放入 LLM 的答案，而是候选依据。对 LLM 的判断请求，需要同时放入 chunk 和搜索候选，Qwen 3.6 会再次验证“该依据是否与当前 chunk 相关”。

传输调试标准

为了防止 AI 在 .gd 文件中随意只挑选“核心函数”发送，或相反将整个文件作为一次 LLM 请求发送，需要能够通过 diff 检查传输前后的差异。检查的对象不是“原始文件整体是否已发送至 LLM”，而是“原始文件中生成的函数/代码片段是否按原始顺序完整追踪，并且每个片段是否已传递给 Retriever 请求”。

在文件展开阶段，首先按路径创建原文块。

# player.gd
extends Area2D

signal hit

@export var speed = 400 # How fast the player will move (pixels/sec).
var screen_size # Size of the game window.

func _ready():
	screen_size = get_viewport_rect().size
	hide()


func _process(delta):
	var velocity = Vector2.ZERO # The player's movement vector.
	if Input.is_action_pressed(&"move_right"):
		velocity.x += 1
	if Input.is_action_pressed(&"move_left"):
		velocity.x -= 1
	if Input.is_action_pressed(&"move_down"):
		velocity.y += 1
	if Input.is_action_pressed(&"move_up"):
		velocity.y -= 1

	if velocity.length() > 0:
		velocity = velocity.normalized() * speed
		$AnimatedSprite2D.play()
	else:
		$AnimatedSprite2D.stop()

	position += velocity * delta
	position = position.clamp(Vector2.ZERO, screen_size)

	if velocity.x != 0:
		$AnimatedSprite2D.animation = &"right"
		$AnimatedSprite2D.flip_v = false
		$Trail.rotation = 0
		$AnimatedSprite2D.flip_h = velocity.x < 0
	elif velocity.y != 0:
		$AnimatedSprite2D.animation = &"up"
		rotation = PI if velocity.y > 0 else 0


func start(pos):
	position = pos
	rotation = 0
	show()
	$CollisionShape2D.disabled = false


func _on_body_entered(_body):
	hide() # Player disappears after being hit.
	hit.emit()
	# Must be deferred as we can't change physics properties on a physics callback.
	$CollisionShape2D.set_deferred(&"disabled", true)

然后留下 AST Parser 创建的片段列表。

Retriever 在发送前也会以块为单位保留 payload。

  chunk_text: |
    func _process(delta):

    		velocity.x += 1
    	if Input.is_action_pressed(&"move_left"):
    		velocity.x -= 1

    		velocity.y += 1
    	if Input.is_action_pressed(&"move_up"):
    		velocity.y -= 1

    	if velocity.length() > 0:
    		velocity = velocity.normalized() * speed
    		$AnimatedSprite2D.play()
    	else:
    		$AnimatedSprite2D.stop()

    	position += velocity * delta
    	position = position.clamp(Vector2.ZERO, screen_size)

    	if velocity.x != 0:
    		$AnimatedSprite2D.animation = &"right"
    		$AnimatedSprite2D.flip_v = false
    		$Trail.rotation = 0
    		$AnimatedSprite2D.flip_h = velocity.x < 0
    	elif velocity.y != 0:
    		$AnimatedSprite2D.animation = &"up"
    		rotation = PI if velocity.y > 0 else 0

验证规则：

expanded_source_block["player.gd"].sha256 == ast_chunk_trace.source_sha256
ast_chunk_trace.chunks[].chunk_order is strictly increasing
retrieval_payload.chunk_id exists in ast_chunk_trace.chunks[].chunk_id
retrieval_payload.chunk_order matches ast_chunk_trace.chunks[].chunk_order

如果此验证失败，则不进行发送。此规则在 .gd 文件中尤为重要。其意图不是将整个 .gd 文件输入 LLM，而是确认从 .gd 中提取的函数/代码片段在不丢失原始路径和原始顺序的情况下能够传递到 Retriever。

当项目作为输入时，首先将其展开为人类可检查的纯文本块。下面的块按 # <relative/path> 单位显示除二进制资产外的文本文件的完整原文。这里也包括像 .md、LICENSE 这类在源码分析中会被排除的文件。文档示例中会保留相对路径内的全部内容，不做省略，以便确认追踪基准。但如果实现中应用了排除策略，被排除的文件将不会发送至 Retriever，而是连同原因一起标记在 excluded_files 中。

二进制资产不会在原始字节的明文正文中放入，但必须保留在 repository path order 和排除/引用列表中。例如 main.tscn 指向 res://art/gameover.wav，则在 LLM 判断输入中，来自 main.tscn 的块、art/gameover.wav 被引用的路径元数据、Retriever 检索结果、用户提示都会放在同一个请求对象里。二进制原始字节本身不会发送给 Retriever 或 LLM。

每个块都会再次转到 Retriever 请求。

retrieval_request
  project_id: "github:godotengine/godot-demo-projects/2d/dodge_the_creeps"
  source_file: "player.gd"
  chunk_id: "player.gd:function:_process"
  prompt_intent: "version_check_and_explain"
  query_terms:
    - "Input.is_action_pressed"
    - "Vector2.ZERO"
    - "position.clamp"
    - "@export"
  candidate_tables:
    - "docs_chunks"
    - "api_mapping"
    - "label_prototypes"

此流程并非 player.gd 独有的特殊处理。只是根据文件类型，片段生成阶段不同。main.gd、mob.gd、hud.gd 会循环执行 analysis_request -> ast_parse_input -> ast_parse_output.chunks[] -> retrieval_request。而像 project.godot、main.tscn 这类不是 AST Parser 目标的文件，则循环执行 analysis_request -> direct_chunk_output.chunks[] -> retrieval_request。

在此示例项目中需要确认的重复发送流程如下。

将项目根目录视为一个 project_id。
按相对路径收集与 Godot 相关的文本文件。
将每个文件展开为带有 # <relative/path> 标题的纯文本块。
将每个纯文本块再次构造成文件级别的 analysis_request。
在每个 analysis_request 中计算 source_sha256。
.gd 文件由 AST Parser 生成 ast_parse_output.chunks[]。
非 AST Parser 目标的包含文件由直接分块器生成 direct_chunk_output.chunks[]。
基于每个 chunk 创建 Retriever 请求。
将 Retriever 结果与 chunk 组合，重复进行 LLM 判定请求。
所有必要的文件/chunk 请求均得到正常响应后，方可将其作为项目级别的判定候选。

也就是说，一个项目会被拆分为如上多个请求。

dodge_the_creeps/project.godot
  -> analysis_request
  -> direct_chunk_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/main.gd
  -> analysis_request
  -> ast_parse_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/player.gd
  -> analysis_request
  -> ast_parse_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/player.tscn
  -> analysis_request
  -> direct_chunk_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/mob.gd
  -> analysis_request
  -> ast_parse_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/mob.tscn
  -> analysis_request
  -> direct_chunk_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/hud.gd
  -> analysis_request
  -> ast_parse_output.chunks[]
  -> retrieval_request per chunk

dodge_the_creeps/hud.tscn
  -> analysis_request
  -> direct_chunk_output.chunks[]
  -> retrieval_request per chunk

此时，即使某个文件或某个块失败，也不会立即确定整个项目。失败的请求会保留为 pending 或 retry 对象，仅累计正常响应的块。项目级别的判断仅在必要的重复请求得到充分响应之后才进行。

重复请求流程

一个项目不会仅凭一次 LLM 请求就作出判定。

项目输入会像下面这样分成多个请求。

project
  -> file requests
  -> AST chunks or direct chunks
  -> retrieval requests
  -> LLM judgment requests
  -> project-level aggregation

各阶段的重复单元如下。

阶段	重复单元
文件扫描	项目内的文件
AST Parser	包含的 `.gd` 文件
直接碎片化	非 AST Parser 目标的包含文件
排除记录	`.md`、二进制等排除目标文件
Retriever	AST chunk 或 direct chunk
Qwen 3.6 判断	AST/direct chunk + 检索依据
项目分类	chunk 判断结果整体

因此，一个项目并不是以真/假结束，而是项目内的多个文件和多个碎片必须分别正常处理。最终的项目判断只能在所有必要碎片的 Retriever/LLM/Validator 结果汇总后进行。

Qwen 3.6 是按需运行的前提，所以比起一次性的大请求，更适合以 AST chunk 或 direct chunk 为单位多次调用。此时已完成的 chunk 可以复用，只有失败或中断的 chunk 需要重新请求。

传递给 AST Parser 的数据

AST Parser 不直接放入提示。

Parser 的输入应尽可能简化，如下所示。

ast_parse_input
  project_id
  source_file
  source_kind
  source_text
  source_sha256

这样分离的原因如下。

可以用相同的源代码在多个提示中重新分析。
即使提示更改，AST 解析结果也可以复用。
防止 Parser 因“提问意图”而对源结构作出不同的解释。
仅在后续的 Retriever/LLM 阶段使用提示来改变判断方向。

AST Parser 输出

Parser 会比直接将整个源代码交给 LLM，更先生成可追踪的片段列表。

ast_parse_output
  project_id
  source_file
  source_sha256
  parse_status
  chunks[]

每个块具有以下信息。

chunk
  chunk_id
  source_file
  span
  node_kind
  symbol_candidates
  api_call_candidates
  code_text
  surrounding_context

项目	说明
`chunk_id`	基于项目/文件/范围的确定性 ID
`span`	行/列或字节偏移范围
`node_kind`	function、class、call、signal、property、scene_node 等
`symbol_candidates`	类名、类型名、方法名候选
`api_call_candidates`	Godot API 调用候选
`code_text`	该片段的原始代码
`surrounding_context`	判断所需的周边代码。不是整个文件，只保留必要范围。

直接片段化输出

不是 AST Parser 目标的包含文件会生成 direct_chunk_output。此输出不是 AST，而是按原始顺序划分的文本/设置/scene 结构结果。

direct_chunk_output
  project_id
  source_file
  source_sha256
  chunk_status
  chunks[]

每个块具有以下信息。

direct_chunk
  chunk_id
  source_file
  chunk_order
  span
  chunk_kind
  chunk_text
  reference_candidates

例：

direct_chunk
  source_file: "main.tscn"
  chunk_order: 3
  chunk_kind: "ext_resource"
  chunk_text: "[ext_resource type=\"Script\" uid=\"uid://c4wt6ace7hycd\" path=\"res://main.gd\" id=\"1_0r6n5\"]"
  reference_candidates:
    - "res://main.gd"

.md类似的被排除的文件不创建 direct_chunk_output，而是保留在 excluded_files 中。

提示与片段合并

提示在 Parser 之后再次合并。

analysis_request.prompt
+ ast chunk 或 direct chunk
+ project/file metadata
-> retrieval_request

示例：

提示意图	首选检索器
“这段代码是什么意思？”	`docs_chunks`
“需要转换为 Godot 4 吗？”	`api_mapping`, `label_prototypes`

| “这段代码是 Godot 3 还是 4？” | docs_chunks, api_mapping, label_prototypes 全部是候选 |

即使在此阶段，也不对特定表格进行特殊处理。根据提示和 AST 片段的性质，寻找所需的官方文档 JSONL 依据。

传递给 LLM 的单元

在 Qwen 3.6 中，不会一次性传递整个原始项目。

LLM 调用单元如下组合。

llm_judgment_request
  prompt
  project_id
  source_file
  chunk_id
  chunk_order
  chunk_kind
  chunk_text
  surrounding_context
  retrieved_evidence
  judgment_contract

这里的 judgment_contract 仍不是最终的 JSONL 架构。当前阶段它是一个告诉 LLM 需要判断什么的请求合约。

retrieved_evidence 仍不是最终的存储架构，而是指代搜索结果集合的抽象字段。后续的存储阶段可以根据证据类型将其拆分为 docs_chunks 证据 ID、api_mapping 证据 ID、label_prototypes 证据 ID 等。本文件中仅将其用作 “检索到的官方文档 JSONL 证据集合” 的含义。

示例：

判断要点：
- 此代码片段是否使用 Godot 3 API
- 是否在 Godot 4 标准下有效
- 是否有迁移依据
- 搜索到的官方文档依据是否与实际代码相关

可复用边界

即使是相同的源代码，如果提示不同，Retriever/LLM 的判断也可能不同。

相反，如果是相同的源代码，AST 解析器的结果可以复用。

步骤	可复用标准
AST 解析	`source_sha256`、`source_kind`、解析器版本
chunk 生成	`source_sha256`、分块版本
Retriever 检索	提示意图、chunk 符号、检索版本
LLM 判断	提示、chunk、证据、模型、提示版本

遵守此边界即可避免“源结构分析”和“依据提问意图的判断”相互混杂。

中断/恢复视角

由于分析请求可能会变长，各阶段必须支持恢复。

最小保存单元：

文件扫描完成状态
每个文件的 AST 解析状态
chunk 生成状态
每个 chunk 的 Retriever 检索状态
每个 chunk 的 LLM 判断状态
Validator 通过状态

如果 RunPod 或本地应用中途停止，只需将正在处理的 chunk 重新置为 pending，已完成的文件和 chunk 可直接复用。

尚未确定的事项

本文档不对以下内容作出确定。

但会记录依赖顺序。

顺序	项目	原因	当前追踪位置
1	AST 解析器实现	根据使用的解析器不同，chunk 结构和失败恢复方式会有所区别。	本文档中的 `AST Parser에 넘기는 데이터`、`AST Parser 출력`
2	最终 JSONL 响应模式	必须确定用何种 JSONL 验证 LLM 判断结果，才能加入 Validator。	`docs/roadmaps/2026-06-25-source-analysis-scoring-architecture.md`
3	score DB 列	在整理 JSONL 响应和 Retriever 依据 ID 后，才能确定存储列。	`docs/retrospectives/2026-06-25-source-analysis-scoring.md`
4	文件系统分类标签	观察 score DB 中累积的判断结果后，再确定项目标签。	`docs/roadmaps/2026-06-25-source-analysis-scoring-architecture.md`
5	SFT/DPO 生成规则	在分类的文件系统累积后另行设计。	`docs/roadmaps/2026-06-25-source-analysis-scoring-architecture.md`

当前唯一确定的事项只有一个。

将提示和源代码合并为一次分析请求，但在 AST 解析器中仅传递源代码和文件元数据，提示在解析器之后的 Retriever/LLM 判定阶段使用。
