- on pass 1 is not a zero. Novelty, churn, thrash and surprise measure change against a previous pass, and pass 1 has none.

Overrides

Pass 4 - advice continue (default), decided stop.

Converged across 4 passes after retracting 1 false positive in Pass 2, noting task-brief AWK section/fence parsing is already tracked upstream in #2406 (#2359 / #2304), and verifying the 2 executing-plans ${BASH:-bash} invocation findings (Issue #2642) with deterministic tests.

Prediction vs reality

Pass	Predicted churn	Actual churn	Surprise	Claim
1	0.45	-	-	Pass 1 enumerates 5 helper scripts and seeds initial defects plus worktree hypothesis.
2	0.35	0.40	0.05	Pass 2 will falsify the sdd.workspace git worktree collision hypothesis and tighten evidence on the must findings.
3	0.10	0.20	0.10	Pass 3 will refine the regression test recommendations for test-executing-plans-scripts.sh and note upstream #2406 on task-brief.
4	0.00	0.00	0.00	Pass 4 will confirm zero new defects and full convergence across all 5 modules.

Coverage

5 modules enumerated, 5 graded.

f-0002 · must · score 1 · confidence 0.95 · effort xs · portability - task-done invokes $sdd/sdd-workspace directly instead of via ${BASH:-bash}, failing with Permission denied (exit 126) when unpacked without +x skills/executing-plans/scripts/task-done:25 runs dir=$(“$sdd/sdd-workspace” “$plan”) directly without “${BASH:-bash}”, so recording task completion fails with exit 126 when installed via marketplace archive extractors that strip +x (see Issue #2040). Evidence: skills/executing-plans/scripts/task-done:25, skills/subagent-driven-development/scripts/review-package:35 Do: Invoke “$sdd/sdd-workspace” via “${BASH:-bash}” “$sdd/sdd-workspace” “$plan” to match task-brief:26 and review-package:35.

Inline task-start helper (skills/executing-plans/scripts/task-start) `script.ep.task_start`

skills/executing-plans/scripts/task-start

f-0001 · must · score 1 · confidence 0.95 · effort xs · portability - task-start invokes $sdd/task-brief directly instead of via ${BASH:-bash}, failing with Permission denied (exit 126) when unpacked without +x Issue #2040 noted that Python zipfile and marketplace skill extractors strip Unix execute bits, so task-brief:26 and review-package:35 invoke sibling scripts via “${BASH:-bash}”. However, skills/executing-plans/scripts/task-start:23 still runs out=$(“$sdd/task-brief” “$plan” “$n”) directly, failing with exit 126 when execute bits are stripped. Evidence: skills/executing-plans/scripts/task-start:23, skills/subagent-driven-development/scripts/task-brief:26 Do: Invoke “$sdd/task-brief” via “${BASH:-bash}” “$sdd/task-brief” “$plan” “$n” in skills/executing-plans/scripts/task-start:23, and add a chmod -x regression check in tests/claude-code/test-executing-plans-scripts.sh.

f-0003 · tracked upstream (#2406 / #2359 / #2304) · correctness - task-brief AWK parser trailing non-Task headings (e.g. ## Self-Review, ## Execution Handoff) and nested fences In skills/subagent-driven-development/scripts/task-brief:30-36, intask is only updated when matching /^#+[ \t]+Task[ \t]+[0-9]+/ and /^```/ { infence = !infence } toggles on any 3-backtick prefix. Because this is already tracked upstream in Issue #2406 and open PRs #2359 and #2304, we narrowed Issue #2642 strictly to the executing-plans ${BASH:-bash} invocation gap (f-0001 and f-0002). Evidence: skills/subagent-driven-development/scripts/task-brief:30-36, skills/writing-plans/SKILL.md:163-204 Do: Deferred to upstream Issue #2406 (#2359 / #2304).

SDD workspace resolver & plan-path marker (skills/subagent-driven-development/scripts/sdd-workspace) `script.sdd.workspace`

skills/subagent-driven-development/scripts/sdd-workspace

f-0006 · note · score 5 · confidence 0.95 · effort xs · state-integrity - sdd-workspace isolates linked git worktrees via per-worktree git rev-parse –show-toplevel hashing Empirical check and tests/claude-code/test-sdd-workspace.sh:203-216 confirm each git worktree gets a distinct top-level path hash and isolated workspace directory. Evidence: skills/subagent-driven-development/scripts/sdd-workspace:56-59, tests/claude-code/test-sdd-workspace.sh:203-216 Do: No change needed.

Retracted

Retraction is a state, not an erasure - a later pass can reverse any of these.

f-0004 (script.sdd.workspace) - sdd-workspace repo-relative plan_id could collide across git worktrees if top-level path resolves to shared git common dir · retracted in pass 2 by the skeptic: git rev-parse –show-toplevel returns each linked worktree’s own directory, as verified in tests/claude-code/test-sdd-workspace.sh:203-216.

Deliberation

Pass 1

skeptic (confidence 0.85) - All 5 modules have concrete file:line evidence, though the sdd.workspace worktree collision hypothesis needs empirical verification in Pass 2 before it can be promoted above should.
builder (confidence 0.95) - Both executing-plans scripts (task-start:23 and task-done:25) can be fixed with one-line ${BASH:-bash} invocations matching Issue #2040.
dreamer (confidence 0.85) - We should check if test-executing-plans-scripts.sh has regression coverage for stripped execute bits and whether task-brief is already tracked in upstream issues/PRs.
empath (confidence 0.90) - Keeping our upstream issue focused strictly on the non-overlapping executing-plans ${BASH:-bash} invocation bug (Issue #2642) avoids duplicating existing PRs (#2359 / #2304 on #2406).

Resolution: 1 edit (plus 5 findings seeded by ponder grade before the argument).

Pass 2

skeptic (confidence 0.98) - Testing git rev-parse –show-toplevel inside a linked git worktree confirms it returns the linked worktree root, not the main repo root, and tests/claude-code/test-sdd-workspace.sh:203-216 already tests worktree isolation. Retract f-0004 as a false positive.
builder (confidence 0.95) - Re-substitute f-0004 on script.sdd.workspace with a verified clean-grade note so unit coverage stays 1.00 across all 5 enumerated scripts while keeping only true defects open.
dreamer (confidence 0.90) - Verify whether task-brief:26 itself works when sdd-workspace loses +x: yes, line 26 uses ${BASH:-bash}, which proves task-start:23 and task-done:25 were missed when the Issue #2040 fix landed.
empath (confidence 0.95) - Retracting the false worktree alarm and deferring f-0003 to upstream #2406 keeps Issue #2642 focused strictly on the reproducible executing-plans exit 126 bug.

Resolution: 1 add, 1 delete.

Pass 3

skeptic (confidence 0.98) - Both open must findings (f-0001 and f-0002) are empirically reproduced: chmod -x on sdd scripts causes task-start and task-done to exit 126.
builder (confidence 0.95) - Include the exact test file location (tests/claude-code/test-executing-plans-scripts.sh) in the evidence and recommendations for f-0001 and f-0002.
dreamer (confidence 0.95) - No additional defects exist across the 5 scripts; all edge cases in argument parsing and path normalization are covered.
empath (confidence 0.95) - Issue #2642 clearly documents the exact two lines (task-start:23 and task-done:25) and reproducer.

Resolution: 1 edit.

Pass 4

skeptic (confidence 0.99) - Zero remaining unverified claims; the false positive on sdd-workspace was retracted in Pass 2 and both open must findings have deterministic reproducers.
builder (confidence 0.99) - Recommendations for task-start and task-done are minimal and self-contained.
dreamer (confidence 0.99) - Cross-script contract between executing-plans and subagent-driven-development is now consistent with Issue #2040.
empath (confidence 0.99) - Report is concise, evidence-backed, and ready for maintainers.

Resolution: no deltas.
