fix(ci): PSScriptAnalyzer has never run — and the two bugs it found - #63
Conversation
The step passed `-Path $ps1.FullName`, where $ps1 is an ARRAY of FileInfo. So .FullName is String[], -Path takes one string, and it threw: Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Path' The catch swallowed that, printed "PSScriptAnalyzer skipped", and the job went green. The step is named "Parse-check (gating) + PSScriptAnalyzer (advisory)" and has never analysed a single line of PowerShell. Analysing per file removes the array. The catch survives for a genuinely absent module on an offline runner, but now says which stage failed, so "could not install" cannot again be mistaken for "found nothing" — and an unavailable analyser emits a ::warning:: rather than passing quietly. Findings are reported with rule, severity, file and line, plus a count by severity, so the debt is a number that can be watched rather than a wall of text. Still advisory. Making it gating without knowing the debt would be guessing; this is the change that produces the number. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Install-Module PSScriptAnalyzerselects the current module version from a registered repository on each run. Rule or severity changes can alter the count without a repository change, which makes the debt measurement non-reproducible. Add-RequiredVersionfor a tested version and update it deliberately.

The two real bugs PSScriptAnalyzer found on the first run it ever performed. Both were invisible for as long as the analyser was dead. PSAvoidUsingBrokenHashAlgorithms — scripts/lib/misc.ps1 defined Get-FileMd5 wrapping Get-FileHash -Algorithm MD5. Zero callers, so no live exposure, but it is the dangerous kind of dead code: this repo verifies every distributed byte with SHA-256, and a ready-made MD5 helper in the shared library is what the next person needing "a hash" would find first. Deleted rather than upgraded — nothing wanted it. PSAvoidOverwritingBuiltInCmdlets — scripts/lib/packages.ps1 defined Install-Package, which is a cmdlet PowerShell already ships (PackageManagement). shell-utils.ps1 dot-sources these libraries into the caller's session, so ours silently replaced the built-in for the rest of that session — for our code and for anything the user ran afterwards. Renamed to Install-SystemPackage; both call sites updated, and no reference outside this file existed. That is the same hazard nvm addresses by calling rather than : never let your own definition shadow what callers believe they are invoking. Not fixed, because it is a false positive: PSReviewUnusedParameter on install.ps1's $Repo. It is used at lines 313-318 — validated against $ValidRepos, then assigned to $script:Repo. The rule does not track that pattern. Verified before dismissing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The other half of "the linters only look like they run". Every "In POSIX sh, X is undefined" check is SC30xx, and every SC30xx is WARNING severity. Gating at -S error therefore sat exactly one notch above the only rules policing this repo's hardest constraint: install.sh must stay POSIX, because it is piped straight into whatever /bin/sh is. Verified both directions. A #!/bin/sh file containing a bash array assignment and a double-bracket test PASSES shellcheck -S error and FAILS -S warning (SC3030, SC3010). So a bashism could have entered the curl-piped installer with a green board. The same notch swallowed SC2115 (recursive removal of a path built from an unset variable) and SC2164 (directory change without a failure guard) — both live hazards in a script that removes temp directories from a trap. The comment justifying the gate claimed "pre-existing warning debt". Measured: ZERO findings across all 17 shell files at -S warning. The debt was already paid; the gate was being held down for a reason that had stopped being true. Also added an explicit POSIX dialect check on install.sh. The lint above uses each file's shebang, but for install.sh the dialect is a distribution promise rather than a preference, so it is asserted rather than inferred from the shebang being correct. Found by the reference-corpus audit; nvm's POSIX discipline is the comparison that made the gap obvious. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Review catch, and a fair one: my fix reduced the ambiguity without removing it. Get-Module -ListAvailable tests discoverability, not importability — a module can sit on disk and still fail to load. And with -ErrorAction Continue a per-file analyser error left $issues untouched, so that file was silently counted as clean and the step printed 'no Error/Warning findings'. A false zero, which is the exact shape this step exists to eliminate. Availability and findings are now separate facts: Import-Module ... -ErrorAction Stop -> analyzerReady per-file Invoke-ScriptAnalyzer -> -ErrorAction Stop, counted Three distinct outcomes, none of which can be mistaken for the others: analyser unavailable ::warning:: PowerShell was NOT analysed N files failed, 0 issues ::warning:: NOT a clean result all files analysed, 0 plain: no findings across all N files The findings notice now carries analysed/total, so a partial run cannot read as a full one.
Found while auditing our shell/PowerShell against the reference corpus. PSScriptAnalyzer is on that list, and we already claim to run it.

Making it gating in the same PR would be guessing at debt nobody had measured. Now the number exists — 85, of which 64 are an accepted convention — so tightening it is a follow-up with a known cost.
Note on the second commit message
Two phrases in
dfc5ef6's body are missing: I used backticks inside a double-quotedgit commit -m, so the shell ran them as command substitution and ate the text. The message should read "the hazard nvm addresses by callingcommand grepinstead of baregrep". The code is unaffected; I could not amend because history rewriting is blocked here.Related

I measured it: zero findings at-S warningacross all 17 shell files; 12 at-S style, of which 11 areSC1091(cannot follow dynamicsource, expected here). That gate can be tightened for free — held back for a broader audit currently in flight.Summary by CodeRabbit
