+## Implementation alignment notes
+
+The `yoi-workspace-server` SQLite bootstrap migration implements this v0 schema as schema version 2. Fresh databases create the typed tables listed above and deliberately do not create canonical `runs`, `hosts`, `workers`, `actors`, or check/validation result tables. Host and Worker HTTP read APIs remain live runtime views backed by local inspection, not DB tables.
+
+For databases created by the earlier workspace-server bootstrap, migration version 2 preserves old `workspaces`, `repositories`, `runs`, `artifacts`, `ticket_projections`, and `objective_projections` data by renaming those tables to `legacy_workspaces`, `legacy_repositories`, `legacy_runs`, `legacy_artifacts`, `legacy_ticket_projections`, and `legacy_objective_projections`, then creating the v0 typed tables. Existing legacy workspace rows are copied into the canonical v0 `workspaces` table with `state = active` when the old row had no typed state. The legacy names are compatibility preservation only and are not canonical schema tables or active write authority.

+
+## Decision
+
+Routing decision: `implementation_ready`
+
+Reason:
+- Ticket includes a concrete `schema-v0.md` artifact defining the Workspace DB canonical schema target and migration stance。
+- Artifact is precise enough to implement a non-breaking schema/migration alignment slice and/or finish design documentation without inventing semantics。
+- Relations are non-blocking context relations; no blocker relation is recorded。
+- Current Workspace backend has an older bootstrap SQLite schema in `crates/workspace-server/src/store.rs` with `runs`, `ticket_projections`, `objective_projections`, and run-linked artifacts, while `schema-v0.md` explicitly says no separate `Run` entity and Host/Worker are live views. This gives a concrete implementation alignment target。
+- Orchestrator worktree is clean on `orchestration` at `b7c890d3`; target worktree / branch is not present。
+- Current queued Ticket is this Ticket only。
+
+Evidence checked:
+- Ticket body / thread / artifacts via `TicketShow` and direct read of `artifacts/schema-v0.md`。
+- `TicketRelationQuery(00001KVNKD56W)`: 2 relation records, no blocking relation reported。
+- `TicketOrchestrationPlanQuery(00001KVNKD56W)`: no records。
+- `TicketList(state=queued)`: this Ticket is the only queued Ticket。
+- Orchestrator git state / branch list checked from `/home/hare/Projects/yoi/.worktree/orchestration` only。
+- Bounded code map:
+  - `crates/workspace-server/src/store.rs` currently owns SQLite migrations and schema versioning。
+  - Current store still has bootstrap `runs` and projection-oriented tables; `schema-v0.md` says v0 should not include separate `runs`, Host/Worker canonical DB tables, generic JSON blobs, or validation result tables。
+  - Current repository/objective/ticket read APIs are filesystem read-through and must keep working。
+
+IntentPacket:
+
+Intent:
+- Turn the Workspace DB canonical schema v0 design into a durable implementation/design artifact and align the current SQLite bootstrap migration where safely non-breaking。
+
+Binding decisions / invariants:
+- Ticket and Objective filesystem records remain the active authority; do not switch write authority to DB。
+- No generic JSON/payload/metadata columns in the v0 canonical schema。
+- Do not add canonical `hosts` / `workers` DB tables; Host/Worker remain live runtime views。
+- Do not add a top-level `runs` canonical table; execution history belongs to Ticket events, TicketWorkerLinks, and Artifacts。
+- Do not add CI/validation result tables in this Ticket。
+- Do not add Actor table in v0; authorship is embedded typed snapshot fields。
+- Keep existing Workspace APIs/tests working。
+- Non-breaking migration is acceptable; destructive migration of existing user DBs is not required in this slice unless clearly safe and tested。
+
+Requirements / acceptance criteria:
+- `schema-v0.md` remains consistent with implemented/bootstrap migration semantics。
+- Workspace-server migration/schema tests cover new v0 schema version and expected tables/absence of forbidden tables。
+- Empty/safe tables from minimal implementation guidance may be added: `repositories`, `ticket_targets`, `ticket_target_paths`, `ticket_worker_links`, `artifacts`, `audit_events`, and supporting Ticket/Objective current/event tables if included。
+- Remove or replace obsolete `runs` table/API/store concept if it conflicts with v0, or clearly demote it to non-canonical compatibility only if removal is out of scope。
+- No canonical host/worker tables are added。
+- Existing filesystem read-through APIs for Tickets/Objectives/Repository pages keep passing。
+- Docs/tests make clear that Host/Worker API is live view and Ticket thread/events are execution authority。
+
+Implementation latitude:
+- If full schema migration is too large, implement the smallest safe migration alignment plus tests and record remaining tables as future follow-up comments。
+- Prefer typed tables/columns over catch-all text/json columns。
+- SQLite schema version can advance if migrations change。
+- `runs` API placeholder may be removed if no longer used; ensure frontend/tests do not depend on it。
+- Keep API surface read-only unless Ticket explicitly requires otherwise; this one does not require write APIs。
+
+Escalate if:
+- Removing current `runs` table/API would break existing accepted frontend or tests in a way that needs product decision。
+- Existing DB migration compatibility requires a complex destructive migration or data backfill policy。
+- Implementing full TicketEvents/TicketWorkerLinks/Artifacts read/write surfaces grows beyond schema/bootstrap alignment。
+- Schema design conflicts with recent Repository/Objectives pages in a way not anticipated by artifact。
+
+Validation plan:
+- `cargo fmt --check`
+- `cargo test -p yoi-workspace-server`
+- `cargo check -p yoi-workspace-server`
+- `git diff --check`
+- `cargo run -p yoi -- ticket doctor`
+- `nix build .#yoi --no-link` if package/source/dependency behavior changes。
+- Deno check/build only if frontend/runs API removal touches frontend。

+  - Head: `5149ab703f63`
+
+Blocking issue:
+
+1. Legacy-upgraded `workspaces` table remains non-canonical and can reject new workspace inserts。
+
+Fresh schema defines canonical `workspaces` as:
+- `workspace_id`
+- `display_name`
+- `state`
+- `created_at`
+- `updated_at`
+
+This matches `schema-v0.md`。
+
+However, legacy migration does not rebuild or demote the old bootstrap `workspaces` table. It only adds `state`:
+- `crates/workspace-server/src/store.rs:198-200`
+  - `ALTER TABLE workspaces ADD COLUMN state TEXT NOT NULL DEFAULT 'active';`
+
+Then `create_schema_v0_tables()` is called, but because it uses `CREATE TABLE IF NOT EXISTS workspaces`, the old table is left in place:
+- `crates/workspace-server/src/store.rs:218-227`
+
+The old v1 bootstrap `workspaces` table had extra `local_root TEXT NOT NULL` and `record_authority TEXT NOT NULL` columns. Those remain on upgraded DBs even though they are not part of canonical v0。
+
+This is not merely cosmetic: `upsert_workspace()` now inserts only v0 columns:
+- `crates/workspace-server/src/store.rs:87-89`
+
+For an upgraded legacy DB, inserting a new `workspace_id` would fail on old `local_root` / `record_authority` NOT NULL columns because the insert no longer supplies them. Updating the already-existing legacy workspace may pass due conflict/update path, which is why current tests do not catch this。
+
+Why this blocks:
+- Upgraded canonical schema does not actually match `schema-v0.md`。
+- Legacy handling is not safe enough because active canonical `workspaces` remains partly old schema and incompatible with the new write path。
+
+Required fix:
+- Rebuild/copy `workspaces` into canonical v0 shape, or otherwise explicitly preserve old workspace data without leaving obsolete NOT NULL columns on the active canonical table。
+- Add tests asserting upgraded `workspaces` column set。
+- Add a post-upgrade insert/upsert test for a new workspace id。
+
+Non-blocking concerns:
+- Existing tests cover fresh forbidden table absence and legacy demotion for old `runs` / projections / artifact / repository tables, but not upgraded `workspaces` column set or post-upgrade insert; add coverage with the fix。
+- Runs card/reference removal is narrow and `/api/runs` removal is test-covered with 404 assertion。

+    - `state`
+    - `created_at`
+    - `updated_at`
+  - Existing legacy workspace rows are copied into canonical `workspaces`, defaulting `state` to `active` when no typed state existed。
+  - Previous legacy demotion for `repositories`, `runs`, `artifacts`, `ticket_projections`, and `objective_projections` is preserved。
+  - Added upgrade test assertions for:
+    - upgraded `workspaces` column set exactly matches v0。
+    - `legacy_workspaces` preserves old obsolete columns。
+    - old workspace data is copied into canonical table。
+    - post-upgrade `upsert_workspace()` succeeds for a new workspace id。
+- `.yoi/tickets/00001KVNKD56W/artifacts/schema-v0.md`

+- Legacy `runs` is preserved only as `legacy_runs`; it does not masquerade as canonical。
+- Host/Worker APIs remain live runtime views, not DB authority。
+- `/api/runs` remains removed/404-tested。
+- Canonical schema avoids generic `metadata_json`, `payload_json`, `diagnostics_json`, and catch-all payload columns。
+- `schema-v0.md` update is narrow and consistent with migration behavior。

+
+## 完了
+
+Workspace DB canonical schema v0 design を `schema-v0.md` artifact と workspace-server SQLite bootstrap/migrations に整合させ、Orchestrator worktree の `orchestration` branch に統合した。
+
+主な成果:
+- SQLite schema version を `2` に進め、canonical schema v0 を実装。
+- Typed v0 tables を追加:
+  - `tickets`
+  - `ticket_events`
+  - `ticket_relations`
+  - `objectives`
+  - `objective_ticket_links`
+  - `repositories`
+  - `ticket_targets`
+  - `ticket_target_paths`
+  - `ticket_worker_links`
+  - `artifacts`
+  - `audit_events`
+- Canonical v0 から top-level `runs`, `hosts`, `workers`, `actors`, validation/CI result tables を除外。
+- Generic `metadata_json`, `payload_json`, `diagnostics_json` のような catch-all payload columns を canonical v0 tables に追加しない方針を維持。
+- `/api/runs` と frontend Runs card/reference を削除し、404 test を追加。
+- Host/Worker APIs は DB authority ではなく live runtime views として維持。
+- Legacy bootstrap tables は non-canonical `legacy_*` preservation tables に demote。
+- Legacy `workspaces` は `legacy_workspaces` に preserve し、active canonical `workspaces` を v0 column set で作り直して既存行を copy。
+- Post-upgrade `upsert_workspace()` for new workspace id が通る regression test を追加。
+- `schema-v0.md` に SQLite version 2 / legacy preservation alignment notes を追加。
+
+統合・検証:
+- Merge commit: `38bd122d merge: workspace db schema v0`
+- Implementation commits: `5149ab70`, `d89ace5b`
+- Reviewer final verdict: approve
+- Validation passed: `cargo fmt --check`, `git diff --check HEAD^1..HEAD`, `cargo test -p yoi-workspace-server`, `cargo check -p yoi-workspace-server`, `deno task check`, `deno task build`, `cargo run -p yoi -- ticket doctor`, and `nix build .#yoi --no-link`。
+
+範囲外:
+- Ticket/Objective write authority migration to DB is not implemented。
+- Host/Worker canonical DB tables are not added。
+- Validation/CI result tables and Actor table are not added。
+- Full TicketEvents/TicketWorkerLinks/Artifacts write surfaces are not implemented beyond schema/bootstrap alignment。
+

+
+<!-- event: implementation_report author: yoi-orchestrator at: 2026-06-22T09:27:06Z -->
+
+## Implementation report
+
+Post-close cleanup completed。
+
+- Stopped child Pods and reclaimed scope:
+  - `yoi-coder-00001KVNKD56W`
+  - `yoi-reviewer-00001KVNKD56W-r1`
+- Removed ignored frontend validation artifacts from child worktree before worktree removal if present:
+  - `web/workspace/node_modules/`
+  - `web/workspace/.svelte-kit/`
+  - `web/workspace/build/`
+- Removed implementation worktree:
+  - `/home/hare/Projects/yoi/.worktree/00001KVNKD56W-workspace-db-schema-v0`
+- Deleted implementation branch:
+  - `impl/00001KVNKD56W-workspace-db-schema-v0`
+- Orchestrator worktree remains clean on `orchestration` at `7a7891d4`。
+
+Root/original workspace was not used for merge/validation/cleanup operations。
