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。
