Plan

Routing hold / waiting-capacity note:

明示 queue review で Ticket body / relations / orchestration plan / workspace state を確認した。

Current decision:

• この Ticket は queued のまま待機。
• 依存 Ticket 00001KV5W3PHW / 00001KV5W3PJ3 は closed で dependency blocker ではない。
• ただし同時 queued の 00001KVFD3YSV CLI inspection を先に受理した。CLI inspection は Plugin discovery / enablement / grants / diagnostics の read-only public surface を作る作業で、host API implementation と同じ Plugin manifest/grant/runtime/diagnostic 周辺に触れる。
• 00001KVFDX9AF https host API とは WASM Plugin Tool runtime host import boundary、Plugin grant model、diagnostics/tests/package behavior の変更面が重なるため do_not_parallelize plan record を残した。

Bounded reason for idle queued:

• conflict / reviewer-coder bottleneck。

Next action:

• 00001KVFD3YSV の implementation/review/merge outcome を確認後、queued のまま再 routing する。
• その時点で https host API Ticket との ordering / conflict も再確認する。

---

Decision

Routing decision: implementation_ready

Reason:

• Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
• Ticket body には、fs host API intent、binding invariants、acceptance criteria、non-goals、validation、escalation-worthy risk domain が実装可能な粒度で揃っている。
• 依存 relation の 00001KV5W3PHW minimal WASM runtime、00001KV5W3PJ3 permission grants、関連 00001KVFD3YSV CLI inspection、00001KVFDX9AF HTTPS host API は closed で blocker ではない。
• Risk domain は filesystem / path safety / file mutation / permission grants だが、Ticket は Plugin-specific grants、no workspace authority inheritance、path normalization、traversal/symlink/root escape rejection、bounds、safe diagnostics、ordinary Tool result path を binding invariants として明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
• 00001KVG0HR96 Component Model migration は Plugin runtime / WIT / host API shape / grants / inspection / packaging に広く触れる migration boundary で、active fs host API と衝突しやすいため waiting note を更新し queued のまま待機する。

Evidence checked:

• Ticket 00001KVFDX9AY body / thread / artifacts。
• TicketRelationQuery(00001KVFDX9AY): depends_on は closed。related Ticket は context であり acceptance blocker ではない。
• TicketOrchestrationPlanQuery(00001KVFDX9AY): prior waiting/do_not_parallelize records を確認。HTTPS host API は closed になったため今回 accepted_plan を記録済み。
• Related completed Tickets:
  • 00001KV5W3PHW — minimal WASM Tool runtime closed。
  • 00001KV5W3PJ3 — Plugin permission grants closed。
  • 00001KVFD3YSV — Plugin read-only CLI inspection closed。
  • 00001KVFDX9AF — Plugin HTTPS host API closed。
• Current queued Ticket 00001KVG0HR96 Component Model migration: migration boundary / conflict waiting note を更新。
• Orchestrator worktree /home/hare/Projects/yoi/.worktree/orchestration: clean。
• Existing branch/worktree: matching 00001KVFDX9AY branch/worktree はなし。
• Visible Pods: self / peers only; spawned child capacity is free。
• Current code map:
  • crates/pod/src/feature/plugin.rs: Plugin resolver, permission grants, static inspection, host API eligibility, HTTPS implementation pattern。
  • crates/pod/src/pod.rs: WASM Tool runtime / host import validation / Tool execution path。
  • crates/manifest/src/plugin.rs: Plugin manifest and permission model。
  • crates/yoi/src/plugin_cli.rs: read-only inspection output should remain compatible with fs host API diagnostics。

IntentPacket:

Intent:

• WASM Plugin Tool runtime に、明示 grant された scoped path のみ read/list/write できる fs host API を追加する。
• Plugin は Pod/workspace filesystem authority を自動継承せず、Plugin-specific host_api.fs grants だけが filesystem authority になる。

Binding decisions / invariants:

• Host API name/domain は fs。
• Broad WASI filesystem exposure は禁止。Plugin は ambient filesystem access を持たない。
• Workspace read/write authority は Plugin に自動継承しない。
• Grant がない read/list/write は fail closed。
• Grants は operation kind (read, list, write) と scoped root/prefix/glob 等の最小安全形を持つ。
• Path normalization、.. traversal rejection、symlink/root escape rejection、allowed root outside rejection は binding。
• Absolute/relative path policy は明確にし、safe default を選ぶ。
• Bounds: path length、read size、write size、directory entry count、diagnostic size。
• Writes は existing file mutation safety と整合し、normalized target file ごとに unsafe race を避ける。
• Diagnostics に file content / secret-like data を漏らさない。
• Tool result path は ordinary Tool result/history path。hidden context injection しない。
• https host API、Service/Ingress/File watcher/package manager は non-goals。

Requirements / acceptance criteria:

• Granted Plugin Tool can read an allowed file。
• Granted Plugin Tool can list an allowed directory within bounds。
• Granted Plugin Tool can write an allowed file within bounds。
• Plugin without matching host_api.fs grant cannot read/list/write。
• Workspace authority is not inherited by Plugin without Plugin grant。
• ../ traversal、symlink escape、allowed-root escape reject。
• Oversize read/write/list fail closed or truncate according to explicit policy。
• File mutation safety avoids unsafe race with existing Write/Edit semantics。
• Diagnostics do not include file content or secret-like data。
• Tests cover allowed read/list/write, missing grant denied, workspace authority not inherited, traversal/symlink/root escape, bounds, diagnostics redaction, safe write conflict behavior。

Implementation latitude:

• Choose exact ABI/import shape consistent with existing yoi-plugin-wasm-1 host import design and current HTTPS host API pattern。
• Choose narrow grant config representation for root/prefix/glob/operation allowlist consistent with current Plugin permission grant model。
• Use tempdir/local fixture files for deterministic tests。
• Choose read/list/write response shape consistent with existing Tool result/error types and CLI inspection structure。
• If write serialization requires reusing existing file mutation primitives, keep it narrow and avoid broad Worker scheduler changes。

Escalate if:

• Safe path/symlink/root escape handling cannot be represented without broad filesystem authority redesign。
• write serialization requires broad Worker scheduler or global mutation system redesign。
• Existing Plugin grant schema cannot safely represent fs scopes without breaking HTTPS grants/CLI inspection。
• Broad WASI filesystem exposure appears necessary。
• Product decision is needed for truncate-vs-fail policy beyond Ticket’s bounded latitude。

Validation:

• Focused plugin fs host API tests。
• Relevant cargo test / cargo check for pod, manifest, yoi as changed。
• cargo fmt --check。
• git diff --check。
• nix build .#yoi --no-link / nix build .#yoi if dependency/package-source-filter changes occur。

Critical risks / reviewer focus:

• Workspace authority leaking into Plugin without Plugin grant。
• Path traversal / symlink / root escape bypass。
• Write race / unsafe mutation behavior。
• File content or secret leakage in diagnostics。
• Unbounded read/list/write outputs。
• Hidden context injection by bypassing normal Tool result path。
• Breaking existing HTTPS host API, permission grants, or CLI inspection semantics。

Next action:

• queued -> inprogress を記録し、Ticket records を Orchestrator worktree に commit してから、専用 implementation worktree を作成し Coder Pod を narrow write scope で起動する。root/original workspace は操作しない。

---

State changed

Ticket body/thread, relation metadata, orchestration plan records, related completed Tickets, Orchestrator worktree, visible Pods, existing branch/worktree, and bounded Plugin fs host API code context were checked. Depends-on blockers are closed, HTTPS host API and CLI inspection related work are closed, and no dirty-state blocker or missing planning decision was found. Component Model migration remains queued with migration/conflict waiting record. Accepting this queued Ticket for implementation before worktree/Pod side effects.

Implementation report

Coder implementation report received / Orchestrator validation:

Implementation commit:

• 717c0999 — plugin: implement fs host api

Summary:

• Added manifest/config support for host_api.fs grants:
  • PluginFsGrant { root, operations }
  • PluginFsOperation::{read,list,write}
• Implemented WASM host import module yoi:fs with:
  • read
  • list
  • write
  • response_len
  • response_read
• Enforced plugin-specific grant checks; Pod/workspace fs authority is not inherited.
• Added path safety:
  • relative-only request paths;
  • .. traversal rejection;
  • configured root must be absolute/non-symlink directory;
  • symlink component/target rejection;
  • canonical allowed-root escape checks.
• Added bounds:
  • request descriptor size;
  • path length;
  • read size with explicit truncation flag;
  • write size fail-closed;
  • directory entry count with explicit truncation flag.
• Added write serialization by normalized target plus O_NOFOLLOW on Unix.
• Kept fs errors/diagnostics bounded and redacted.
• Extended Plugin CLI inspection to show configured fs grants.

Plan

Review dispatch:

Reviewer Pod yoi-reviewer-00001KVFDX9AY を read-only scope で起動した。

Review target:

• worktree: /home/hare/Projects/yoi/.worktree/00001KVFDX9AY-plugin-fs-host-api
• branch: impl/00001KVFDX9AY-plugin-fs-host-api
• commit: 717c0999

Reviewer focus:

• recorded intent / invariants / acceptance criteria に対する適合性。
• filesystem access が grant checks の前に発生しないこと。
• Workspace/POD filesystem authority が Plugin に自動継承されていないこと。
• traversal / symlink / root escape protections が canonicalization races を含め妥当であること。
• read/list/write bounds と truncate-vs-fail-closed policy が明確で enforce されること。
• write serialization by normalized target と O_NOFOLLOW が既存 file mutation safety と整合すること。portability issue がないこと。
• diagnostics に file content / secret-like data が漏れないこと。
• ordinary Tool result/history path だけに戻ること。
• tests が allowed read/list/write、missing grant、no workspace inheritance、traversal、symlink/root escape、bounds、redaction、write safety を十分に覆うこと。
• manifest/permission grant schema と CLI inspection changes が既存 HTTPS grants / Plugin inspection behavior と互換であること。
• HTTPS host API と Component Model migration が non-goals として保たれていること。

Next:

• Reviewer output を確認し、approve なら Orchestrator worktree への merge/validation/cleanup/close-ready 処理へ進む。request_changes なら blocker を記録して Coder に戻す。
