21-27: Fix markdownlint MD040: add language to fenced block.Specify a language (use text) for the ASCII diagram.
-``` +```text Frontend (5s intervals) → HTTP API → Supabase → Full Task Data ↓ ↓ ↓ ↓ TanStack Query FastAPI PostgreSQL All descriptions ETag Caching projects_api TEXT fields every request Smart Polling TaskService No indexes 250KB+ payload--- `51-57`: **Fix markdownlint MD040: add language to fenced block.** Endpoints block should also declare a language. ```diff -``` +```text GET /api/projects/{id}/tasks - Lists all tasks (with descriptions) GET /api/tasks/{id} - Single task details POST /api/tasks - Create task PUT /api/tasks/{id} - Update task DELETE /api/tasks/{id} - Delete task--- `115-122`: **Avoid redundant/ineffective indexes; define update strategy for FTS.** - GIN tsvector index + separate btree on description is likely redundant; btree won’t help substring/FTS. - Later you add a stored search_vector without describing how it’s maintained. Prefer a generated column and index that doesn’t require triggers. Also use CONCURRENTLY for all online index builds. ```diff - CREATE INDEX CONCURRENTLY idx_archon_tasks_description_btree - ON archon_tasks(description); + -- Drop the btree text index unless you have equality lookups on description. - ALTER TABLE archon_tasks ADD COLUMN search_vector tsvector; - CREATE INDEX idx_tasks_search_vector ON archon_tasks USING gin(search_vector); + ALTER TABLE archon_tasks + ADD COLUMN search_vector tsvector + GENERATED ALWAYS AS (to_tsvector('english', coalesce(description,''))) STORED; + CREATE INDEX CONCURRENTLY idx_tasks_search_vector + ON archon_tasks USING gin(search_vector);If prefix/ILIKE search is needed, consider pg_trgm GIN/GIST. Otherwise, keep only the FTS GIN.
Also applies to: 292-301
155-158: Unify event naming (underscore vs colon).Doc mixes task_created/task_updated and task:created/task:updated. Pick one convention and use it consistently across specs and examples.
-'task:created' | 'task:updated' | 'task:deleted' +'task_created' | 'task_updated' | 'task_deleted'(or adopt the colon style everywhere—just be consistent.)
Also applies to: 310-312
191-195: Clarify “0ms” latency claim.“Instant (0ms)” is unrealistic and conflicts with later “<100ms”. Replace 0ms with <100ms.
- **Real-time Updates:** Instant (0ms vs 5000ms polling) + **Real-time Updates:** <100ms vs 5000ms polling
210-215: Note migration caveat for CONCURRENTLY.State that CREATE INDEX CONCURRENTLY/ DROP INDEX CONCURRENTLY must run outside transaction blocks; configure your migration tool accordingly (e.g., Alembic: set transactional_ddl=False for that op).
I can add an Alembic snippet if useful.
168-171: Add UX guardrails for virtual scrolling.Document preserving keyboard focus/aria relationships and estimating row size variability to avoid jumpy scroll.
Also applies to: 326-331
224-233: Add measurement plan ownership.Name the owners and dashboards for KPIs (network KB/request, list response p95, socket event lag p95) so results are auditable.

…ion steps
Add detailed implementation reviews and validation protocols for the first two steps
of the task performance optimization initiative:
## Step 01: Backend - Exclude Large Fields (01-backend-exclude-large-fields-validation.md)
- Validated lightweight task list implementation excluding description/metadata fields
- Confirmed 60-80% payload reduction for typical task lists
- Verified all acceptance criteria met with proper error handling
- Tests passing: filtering, sorting, and field exclusion working correctly
## Step 02: API - Task Details Endpoint (02-api-task-details-endpoint-validation.md)
- Validated new GET /api/tasks/{task_id}/details endpoint implementation
- Confirmed proper 200/404/500 status code handling with detailed logging
- Verified Logfire integration with exc_info=True for stacktrace capture
- All 3 test scenarios passing (found/not-found/error cases)
- Router properly integrated and service layer robustly implemented
Both implementations follow beta guidelines:
- Clear failure modes with detailed error messages
- No silent failures or data corruption risks
- Professional dependency management (httpx pinning for TestClient compatibility)
- Comprehensive test coverage with centralized mocking infrastructure
The validation confirms both steps are production-ready for beta deployment,
meeting all technical requirements and quality standards.

Row-by-row truncation via client; use a single SQL UPDATE and avoid pulling large payloads.
Current logic downloads and rewrites each description. Prefer DB-side update and count affected rows; also paginate if you keep client-side logic.
DB-side approach to print and run manually (safe and fast):
UPDATE archon_tasks
SET description = left(description, 49997) || '...'

FastAPI will nest your envelope under "detail" unless you add an exception handler.
Raising HTTPException with a dict detail yields {"detail": {...}}. To match the contract (top-level detail/error_code/context), add an exception handler for APIError.
Add this example to the spec:
from fastapi import FastAPI, Request
from fastapi.responses import JSONResponse
from python.src.server.utils.api_errors import APIError
def install_api_error_handler(app: FastAPI) -> None:
@app.exception_handler(APIError)
async def _api_error_handler(request: Request, exc: APIError):
payload = exc.detail if isinstance(exc.detail, dict) else {"detail": str(exc.detail)}
return JSONResponse(status_code=exc.status_code, content=payload)Also consider a handler for RequestValidationError to emit the unified 422 envelope.

In python/src/server/api_routes/tasks_api.py, update the GET /tasks/{task_id}/details handler to accept an authenticated user (e.g. current_user: User = Depends(get_current_user)) and verify the task belongs to that user’s tenant—raise 404 when the task isn’t found or isn’t visible to prevent cross-tenant leaks.

log/02-api-tasks-details-endpoint.protokoll.md around lines 8 to 11: the GET
/tasks/{task_id}/details handler must require authentication and enforce tenant
isolation; update the FastAPI route in python/src/server/api_routes/tasks_api.py
to add a parameter current_user: User = Depends(get_current_user) (and import
Depends and get_current_user if missing), fetch the task as before but verify
task.tenant_id == current_user.tenant_id (or equivalent visibility check) and if
not equal or task not found raise HTTPException(status_code=404); keep existing
200 and 500 behavior and ensure no cross-tenant data is returned.

| - Neu: `migration/07_add_archon_tasks_indexes.sql` | ||
| - `CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_archon_tasks_project_status_order ON archon_tasks(project_id, status, task_order);` | ||
| - Optionaler, auskommentierter GIN-Index auf `to_tsvector('english', description)`. | ||
| - Hinweise: Validierung (\di, EXPLAIN, `pg_stat_user_indexes`) und Rollback. | ||
| - Geändert: `migration/complete_setup.sql` | ||
| - Direkt nach `CREATE TABLE IF NOT EXISTS archon_tasks (...)` eingefügt: | ||
| - `CREATE INDEX IF NOT EXISTS idx_archon_tasks_project_status_order ON archon_tasks(project_id, status, task_order);` | ||

🛠️ Refactor suggestion
Include created_at in the composite index to match ORDER BY.
Service queries order by task_order, created_at. Current index (project_id, status, task_order) may still require a sort on created_at. Add created_at as the 4th key to enable full index-order scans.
Suggested upgrade SQL:
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_archon_tasks_project_status_order
- ON archon_tasks(project_id, status, task_order);
+CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_archon_tasks_proj_status_order_created
+ ON archon_tasks(project_id, status, task_order, created_at);And in complete_setup.sql:
-CREATE INDEX IF NOT EXISTS idx_archon_tasks_project_status_order
- ON archon_tasks(project_id, status, task_order);
+CREATE INDEX IF NOT EXISTS idx_archon_tasks_proj_status_order_created
+ ON archon_tasks(project_id, status, task_order, created_at);Committable suggestion skipped: line range outside the PR's diff.

🛠️ Refactor suggestion
Don’t return tuples on validation failure—raise a typed API error.
Per guidelines, fail with a 422 exception rather than returning (False, error). Tie this to the unified error contract.
-if description is not None and isinstance(description, str) and len(description) > MAX_DESCRIPTION_LENGTH:
- logger.error(f"Description too long | length={len(description)} > max={MAX_DESCRIPTION_LENGTH}")
- return False, {"error": f"description exceeds {MAX_DESCRIPTION_LENGTH} characters"}
+if description is not None and isinstance(description, str) and len(description) > MAX_DESCRIPTION_LENGTH:
+ logger.error("Description too long | length=%d > max=%d", len(description), MAX_DESCRIPTION_LENGTH)
+ raise validation_error(

+ message="Task description exceeds maximum length",
+ error_code="TASK_DESCRIPTION_TOO_LONG",

review/06-server-side-validation-review.md around lines 55 to 59, the validator
returns a tuple (False, {...}) on failure; change this to raise the unified API
422 error instead. Replace the return with raising the project's typed
unprocessable entity exception (or an HTTP 422 exception) using the unified
error contract format (include the standardized error code/key and a clear
message like "description exceeds X characters" and any metadata such as actual
length and max). Ensure callers expect exceptions or the global handler maps
this typed exception to a 422 response.
