Epic 6, Story 6, Task 57: BR-039 Cascade whitelist / security prompt usability (vendor)

Task ID: E6:S06:T57
Status: ✅ COMPLETE (repo implementation — see § Task closure policy; BR-039 remains open for Cascade/vendor product state)
Priority: CRITICAL
Estimated Effort: Small (repo) / Unknown (vendor)
Created: 2026-03-31
Last updated: 2026-04-02 — RW -k repair v0.6.6.57+6 (SemVer v0.4.705+6 — v0.4.703+4 / v0.4.704+5 both stale on remote)
Version: v0.6.6.57+6
Code: E6S06T57

Upstream: BR-039 – Cascade Whitelist Security Prompt Usability Blocker

Planning Artifact (IPW): IPW-E6S06T57-br039-vendor-blocker-planning.md

Task closure policy (2026-04-02)​

This task tracks ai-dev-kit repository work: traceability to BR-039, honest evidence, workarounds, and language that does not falsely claim a vendor fix.

It does not require (and never again requires) a Windsurf or Cascade-in-Windsurf reproduction by the implementing maintainer:

  • Windsurf is not in use for this project; there is no paid subscription to run it.
  • Cursor is the standard IDE for maintainer workflows (including RW).
  • Product pass/fail on Cascade remains tracked on BR-039 for vendor fixes, other subscribers, or community re-verification — outside this task’s closure criteria.

Closing T57 as COMPLETE is therefore repo-complete, not “BR-039 resolved.”

Input​

Scope​

In this repository (ai-dev-kit):

  • Maintain traceability from BR-039 to this task while the BR stays open.
  • Document impact on RW / terminal-heavy workflows and link BR-038 where relevant.
  • Capture vendor escalation posture, Cursor workaround, and re-verification guidance for others who can still exercise Cascade builds — without assigning Windsurf runs to the maintainer.

Out of scope: Fixing Cascade product code (tracked externally / vendor). Ongoing Windsurf/Cascade testing by this maintainer (no tool access / subscription).

Deliverable​

  1. BR-039 shows Implementing Task: E6:S06:T57 and stays aligned on product status.
  2. Evidence (historical + environment): dates, honest attempted/verified language — no false “fixed.”
  3. When someone validates a vendor fix: update BR-039 (not necessarily this task — T57 may remain COMPLETE as historical repo anchor).

Acceptance Criteria​

  • AC1: BR-039 linked to this task; kanban and FR/BR board rows include task link (while BR open) or completed trail per board hygiene.
  • AC2: Maintainer execution environment documented: Cursor standard; no obligation to re-run Cascade repro in Windsurf for task closure (subscription/access not available).
  • AC3: Documented workaround for this repo: Cursor (or equivalent) for full RW cadence; BR-039 Workarounds section consistent.
  • AC4: Documentation and release notes use attempted/verified language only; no “fixed/resolved/completed” for Cascade before evidence-backed validation on BR-039.
  • AC5: T57 can be COMPLETE while BR-039 remains IN PROGRESS — task = repo work; BR = product truth.

Version Anchor​

  • v0.6.6.57+6 (RW -k repair) — outward v0.4.705+6; +5 / v0.4.704+5 also blocked on remote.
  • v0.6.6.57+5 (RW -k repair / Option B) — outward v0.4.704+5 attempted; supersedes v0.4.703+4 tag attempt for +4.
  • v0.6.6.57+4 (RW -k E6:S06:T57) — T57 COMPLETE repo-side; § Task closure policy; dev-kit-kanban-versioning-rw-integration.md § RW -k.
  • v0.6.6.57+3 — E1 / E2 historical evidence + Cursor-only note (prior full RW on T57).

Evidence (historical)​

The tables below record what was captured when Windsurf was still referenced; they support BR-039 accuracy for others hitting Cascade. They are not ongoing task requirements.

E1 — 2026-04-02 (historical; IPW checklist / agent session)​

FieldValue
date_utc2026-04-02 14:44 UTC
tool_versionWindsurf (macOS): 1.9577.27 (historical reference). Executor: Cursor (validators).
scenarioA) BR-039 § repro (interactive Cascade UI) — not run in agent session. B) validate_branch_context.py --strict; validate_rw_task_complete.py --requested E6:S06:T57 on epic/6-framework-management.
expectedA) After whitelist, repeated command should not re-prompt (per BR-039). B) Validators exit 0.
observedA) Not executed (UI). B) Both validators exited 0.
resultblocked for A (product repro); auxiliary pass for B (repo shell only).
notesHistorical. Maintainer no longer uses Windsurf / no subscription — see § Task closure policy.

E2 — 2026-04-02 (historical; maintainer Cursor-only)​

FieldValue
date_utc2026-04-02
tool_versionPrimary IDE: Cursor. Windsurf: not used going forward (subscription).
scenarioCascade repro in Windsurf — not required for T57 closure.
expectedN/A for this task’s ACs under current policy.
observedMaintainer standard workflow: Cursor.
resultCOMPLETE (repo task) per AC2 / AC5; BR-039 still valid for Cascade product tracking.
notesAny future pass/fail on Cascade belongs in BR-039 evidence log by whoever can run the vendor IDE.

Execution Checklist (from IPW; adapted)​

  • Confirm environment under which this repo is maintained — Cursor (standard).
  • No standing requirement for maintainer to run BR-039 in Windsurf.
  • Terminal-heavy workflow continuity in maintainer IDE — RW / validators runnable from Cursor.
  • Evidence and BR-039 aligned with attempted/verified language.
  • Decide T57 COMPLETE (repo) vs BR-039 IN PROGRESS (product) — see § Task closure policy.
  • Update boards: remove T57 from active MoSCOW; add kanban-completed entry when applicable.
