Raw Blame History

作成

LocalTicketBackend によって作成されました。

Intake summary

ユーザー要望を調査 Ticket ではなく concrete implementation Ticket として作成した。調査済み結論に基づき、WebFetch が application/pdf を pdf-extract で page-delimited Markdown-ish text として返せるようにする。Poppler/Pdfium/subprocess/OCR/semantic Markdown 化は非ゴール。既存 WebFetch safety bounds と HTML/text behavior は維持する。

State changed

Intake 済み。Orchestrator は implementation routing として扱える。実装 side effect / worktree 作成 / coder 起動はここでは行っていない。

State changed

Ticket を workspace-panel が queued にしました。

Decision

Routing decision: implementation_ready_parallel

Reason:

  • Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
  • User standing directive: blocker が無いものは並列実行する。現在の 00001KVJABS1A は Profile scope review 中であり、WebFetch PDF 実装とは domain/file conflict がないため並列化できる。
  • Ticket body は調査済みの PDF extraction 方針、pdf-extract 採用理由、binary path 分離、page-delimited Markdown-ish output、metadata、bounds、non-goals、validation を実装可能な粒度で定義している。
  • 未解決 relation blocker はない。
  • Orchestrator worktree は clean、matching branch/worktree はなし。
  • Risk domain は security / dependency / public-api / output-bounds だが、Ticket は existing WebFetch network safety、max_response_bytes / max_output_bytes、unsupported binary rejection、no OCR/semantic Markdown/native dependency を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。

Evidence checked:

  • Ticket 00001KVJA7V2R body / thread / relations / artifacts。
  • TicketRelationQuery(00001KVJA7V2R): no blockers。
  • TicketOrchestrationPlanQuery(00001KVJA7V2R): no previous plan records; accepted plan recorded now。
  • Workspace state:
    • Orchestrator worktree clean at 36b9ed45。
    • queued: 00001KVJA7V2R, 00001KVJDJD02。
    • inprogress: 00001KVJABS1A review only。
    • no matching WebFetch PDF branch/worktree。

IntentPacket:

Intent:

  • Extend WebFetch so application/pdf can be fetched and returned as bounded, page-delimited text suitable for LLM reading。
  • Use pdf_extract::extract_text_from_mem_by_pages() and present output as Markdown-ish page sections, not semantic PDF-to-Markdown。

Binding decisions / invariants:

  • Keep WebFetch as fetch/extraction tool; no summarization or research orchestration。
  • PDF bytes must not go through the UTF-8 text / reject_binary() path。
  • Preserve private/local host rejection, bounded redirects, Content-Length / max_response_bytes, max_output_bytes, embedded credential rejection, untrusted content warning。
  • Initial supported MIME is application/pdf only; no extension sniffing or application/octet-stream PDF guessing。
  • No Poppler/Pdfium/subprocess/native dependency/OCR/scanned-PDF support/table reconstruction/cache。
  • Existing HTML/text/JSON/XML behavior and html_extraction metadata must not regress。
  • New metadata should use pdf_extraction with method/pages/readable/diagnostic information。

Requirements / acceptance criteria:

  • Valid PDF returns ## Page 1, ## Page 2, etc. page-delimited bounded text。
  • transformed_as communicates pdf_text_by_pages or equivalent, not semantic Markdown。
  • output_truncated is correct when PDF text exceeds max_output_bytes。
  • Malformed/encrypted/textless PDFs do not panic; return diagnostic error or readable=false metadata。
  • Non-PDF unsupported binary remains rejected。
  • Focused WebFetch tests and relevant cargo/fmt/diff validation pass。

Next action:

  • Record queued -> inprogress and commit Ticket records before creating implementation worktree and spawning Coder。

State changed

Ticket body/thread, relation metadata, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded WebFetch/PDF context were checked. There is no unresolved blocking dependency, no conflicting inprogress implementation, and no missing planning decision. Accepting this queued Ticket for parallel implementation before worktree/Pod side effects.

Implementation report

Implementation orchestration start:

  • Acceptance records were committed on Orchestrator branch: e752a720 ticket: accept webfetch pdf and intake gate。
  • Created implementation worktree /home/hare/Projects/yoi/.worktree/00001KVJA7V2R-webfetch-pdf-text on branch impl/00001KVJA7V2R-webfetch-pdf-text at e752a720。
  • Spawned Coder Pod yoi-coder-00001KVJA7V2R with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。
  • Coder task explicitly forbids root/original workspace implementation, semantic PDF Markdown/OCR/native dependency scope creep, merge, Ticket close, and cleanup。

Next action:

  • Wait for Coder implementation report, then inspect branch diff/validation evidence and route to Reviewer。

Implementation report

Coder implementation report received from yoi-coder-00001KVJA7V2R.

Implementation commit:

  • b1af95ad web: fetch pdf text by pages

Changed areas reported:

  • crates/tools/src/web.rs:
    • Added application/pdf handling for WebFetch。
    • PDF bytes bypass UTF-8 / reject_binary() text path。
    • Uses pdf_extract::extract_text_from_mem_by_pages() inside tokio::task::spawn_blocking。
    • Returns Markdown-ish page sections like ## Page 1, ## Page 2。
    • Adds pdf_extraction metadata with method/page/readability/diagnostic fields。
    • Keeps existing html_extraction semantics intact。
    • Preserves unsupported binary MIME rejection。
    • Added deterministic in-memory PDF test fixtures and tests for PDF page-delimited output, output truncation, malformed PDF diagnostic error, and unsupported binary MIME rejection。
  • crates/tools/Cargo.toml: added pdf-extract = "0.10.0"。
  • Cargo.lock: updated for pdf-extract and transitive dependencies。
  • package.nix: updated cargoHash to sha256-rvsjn4BBxd9vt4nytPgUh4l/OQCRpqHbUR4jHoH589U=。

Coder validation reported as passing:

  • cargo fmt --check
  • cargo test -p tools web
  • cargo check -p tools
  • git diff --check
  • nix build .#yoi --no-link

Dependency / package impact:

  • New Rust dependency: pdf-extract 0.10.0。
  • Nix vendor hash updated and nix build .#yoi --no-link passed。

Known risks / deferrals:

  • Only application/pdf is supported; no extension sniffing or application/octet-stream PDF guessing。
  • No OCR, scanned-PDF support, table reconstruction, cache, subprocess, Poppler, or Pdfium integration。
  • Malformed PDFs return diagnostic extraction error; textless PDFs are represented with readable=false metadata when extraction succeeds but no text is found。

Orchestrator evidence checked before review dispatch:

  • Implementation worktree is clean。
  • HEAD is b1af95ad。
  • Diff from acceptance e752a720..HEAD is one implementation commit touching 4 files, about 552 insertions / 23 deletions。
  • git diff --check e752a720..HEAD produced no diagnostics。

Next action:

  • Dispatch Reviewer for r1 review against Ticket requirements, with focus on WebFetch network/binary safety preservation, PDF extraction bounds/metadata, dependency/Nix impact, malformed/textless behavior, unsupported binary rejection, and HTML/text regression safety。

Plan

Review dispatch:

  • Spawned Reviewer Pod yoi-reviewer-00001KVJA7V2R-r1 against implementation branch impl/00001KVJA7V2R-webfetch-pdf-text。
  • Review target commit: b1af95ad web: fetch pdf text by pages。
  • Review baseline: e752a720。
  • Reviewer task focuses on WebFetch network safety preservation, PDF binary path separation, response/output bounds, pdf_text_by_pages metadata accuracy, malformed/textless behavior, unsupported binary rejection, existing HTML/text regression safety, dependency/package impact, and Nix validation。
  • Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。

Review: approve

Verdict: approve

確認範囲:

  • Ticket contract / Orchestrator IntentPacket。
  • Implementation diff: e752a720..b1af95ad。
  • 主な対象:
    • crates/tools/src/web.rs
    • crates/tools/Cargo.toml
    • Cargo.lock
    • package.nix

Approval evidence:

  • WebFetch safety pipeline は PDF rendering 前にも共有されている。
    • URL validation。
    • Redirect validation。
    • Content-Length rejection。
    • Bounded body read。
  • PDF classification は exact application/pdf のみで、extension sniffing や application/octet-stream guessing は追加されていない。
  • PDF path は reject_binary() / UTF-8 text decoding を bypass し、pdf_extract::extract_text_from_mem_by_pages() を spawn_blocking 内で使っている。
  • Output は ## Page N 形式の page-delimited text。
  • transformed_as / pdf_extraction.method は pdf_text_by_pages を使い、semantic Markdown fidelity は主張していない。
  • PDF rendering 後も max_output_bytes truncation が適用されている。
  • Existing HTML extraction metadata は維持され、PDF result は html_extraction = null / pdf_extraction populated になる。
  • pdf-extract dependency inspection では Poppler/Pdfium/subprocess/OCR runtime dependency は見つからない。

Blocking issues: none。

Non-blocking concerns / follow-ups:

  • Valid multi-page PDF、PDF output truncation、malformed PDF error、unsupported non-PDF binary rejection の tests はあるが、encrypted/textless PDF と oversized PDF Content-Length の dedicated tests は無い。実装上は textless pages は readable=false metadata、Content-Length rejection は content-type rendering 前の shared path で covered されるため、この Ticket では blocking ではない。
  • Malformed PDF は pdf_extraction metadata付き JSON result ではなく ToolError を返すが、Ticket は “diagnostic error or readable=false metadata” を許容しているため OK。

Reviewer validation:

  • cargo fmt --check: passed。
  • git diff --check e752a720..HEAD: passed。
  • cargo test -p tools web: passed, 19 tests。
  • cargo check -p tools: passed。
  • cargo tree -p pdf-extract: inspected; native PDF runtime dependencyなし。
  • nix build .#yoi --no-link: passed。

Worktree status at review end: source tree clean; ignored target/ only。
