0.9.4 -- Sprint 14

Sprint 14 wrap.

Added

• history-compression skill formalized at confidence: medium (#340)

Changed

• README refreshed: pre-commit 6-check description, ascii-sweep.py docs, ASCII conversion of file-tree, expanded pre-commit one-liner (#342)
• Label taxonomy slimmed from 45 to 32 labels; 84 issues migrated with triple-verification protocol (PRE/OP/POST per-issue, 0-count gate per label delete) (#347)
• sync-squad-labels.yml follow-ups: priority:p3 + platform:* now managed by workflow; dead hasCopilot code removed (#350)

Meta

• CHANGELOG editorial: Sprint 13 retro pointer relocated from [Unreleased] to [0.9.3] to match prior-sprint convention (#343, PR #344)

Full notes: CHANGELOG.md

0.9.3 -- Sprint 13

Highlights

• ASCII-sweep of all repo Markdown files (124 of 163 files, 2,501 non-ASCII chars replaced) (#322 part A)
• pre-commit ASCII scan extended to .md and .sh (was .ps1 only, allowed 134 hits to land in ARCHITECTURE.md) (#322 part B)

0.9.1 - Sprint 11: Architecture refresh and tools hardening

0.9.1 -- Sprint 11 (formerly Sprint T): Architecture refresh and tools hardening

Fixed

• scripts/windows/tools/auth.ps1 + scripts/windows/setup.ps1: applied 0 reset mitigation at 5 sites; eliminates spurious failure detection when callers check exit codes downstream (closes #292)

Added

• .squad/skills/pwsh-lastexitcode/SKILL.md: documents the 0 propagation gotcha across pwsh & script-call boundaries; canonical fix is 0 = 0 after expected-failure commands (closes #288, surfaced by #277)
• CONTRIBUTING.md "PowerShell Exit Code Discipline" section referencing the new skill
• .squad/decisions/doc-and-jiminy-automation.md: decision record codifying the post-batch Jiminy audit gate and the Doc subagent worktree pattern (closes #289, #290)
• .squad/retros/2026-05-17-sprint-11-retro.md: Sprint 11 retrospective -- first sprint exercising the #293 SOPs; 6 PRs merged, sequential Goofy pattern validated, Group EE static-source tests added

Changed

• scripts/windows/auth.ps1 moved to scripts/windows/tools/auth.ps1 for consistency with the per-tool layout introduced in #195; all callers updated (closes #230)
• ARCHITECTURE.md: refreshed file trees + agent/skill rosters + hook + CI layout to reflect Sprint 8-hotfix through Sprint 10 changes (closes #229)
• hooks/pre-push: documented advisory-only intent of the PSScriptAnalyzer step (closes #233)
• CONTRIBUTING.md "Why is PSSA advisory in pre-push?" subsection codifies the advisory model so the || true is not incorrectly "fixed" (closes #233)
• .squad/templates/loop.md, ceremonies.md, and Doc/Jiminy charters: codify post-batch Jiminy audit gate + Doc subagent worktree pattern (closes #289, #290)
• CONTRIBUTING.md "Squad Operational Gates" section -- human-facing summary of the Doc worktree + Jiminy auto-dispatch SOPs
• hooks/pre-commit Source of Truth allow-list extended to include canonical .squad/decisions/*.md files
• Sprint 11 end-of-session cleanup: no straggler branches/worktrees

Full Changelog: 0.9.0...0.9.1

0.9.0 -- Sprint S: version pinning, hygiene, and Doc fact-checking

Sprint S: Version pinning, hygiene, and Doc fact-checking

Highlights

Version-pin anti-pattern eradicated (#255)

• Idempotency guards (command -v X && exit 0) silently froze stale versions in CI
• Linux installed squad-cli 0.8.25 (not 0.9.4); copilot-cli pin 0.0.339 was opaque and unmatched on npm; gh was unpinned everywhere
• Pin sweep across Linux + macOS + Windows: squad-cli 0.9.4, copilot-cli 1.0.48 (@github/copilot, switched from deprecated @githubnext/github-copilot-cli), gh 2.92.0
• Windows pivoted from winget GitHub.Copilot (the VS extension, wrong product) to npm install -g @github/copilot
• New .squad/skills/tool-version-pin/SKILL.md codifies the anti-pattern + canonical fix
• CONTRIBUTING.md "Tool Version Pin Enforcement" section + pre-PR validation step (npm view "@pkg@version" version)

Cross-platform hygiene

• .gitattributes pins *.ps1 to CRLF (#231)
• -Encoding ASCII on all Windows Set-Content / Add-Content calls (#234)
• Logging consolidation: setup.sh + uninstall.sh now source scripts/linux/lib/log.sh (#223)
• Uninstall core.hooksPath reset uses local scope (matching setup) + resets \0 so the expected non-zero exit doesn't fail the step (#271)

CI reliability

• E2E summary job fails workflow if any platform job fails -- ends silent green-dashboard regressions (#253)
• Regression sentinel: e2e-install.yml captures squad --version and fails on "session persistence may fail" warning; static installer tests assert correct npm package + stderr capture (#255)
• YAML doubled-single-quote escapes in bash -lc step bodies prevent inner apostrophes from terminating wrapper

Squad governance

• Doc (Fact Checker) auto-triggers on review/verify/audit tasks -- caught the wrong-npm-package BLOCKER on #282 before merge
• Jiminy dispatch SOP: Coordinator MUST invoke Jiminy after every 3+ agent batch and at session-end (#280)
• Ralph "Develop Commit Ban" charter: all agent history.md updates flow through short-lived branch + PR or Scribe drain
• CONTRIBUTING.md "Group Letter Assignment" + "CHANGELOG Conflict Strategy" sections codify recurring patterns
• .gitignore ignores *.tgz so squad upgrade artifacts never accidentally land in commits

Tests added this sprint

• test_nvm_bootstrap.sh T6-T9 (pin enforcement), T10-T11 (regression sentinel)
• test_windows_setup.ps1 Group DD (pin enforcement), Group X (hooks), Group Z (encoding)
• test_precommit_hygiene.sh pre-push section

Stats

• 12 PRs merged (#274 - #285)
• 8 agents dispatched across the sprint
• 1 release PR (#287)
• Diff vs 0.8.0: 63 files, +5007 / -261

See CHANGELOG.md for full entry list.
