`pmg setup doctor` reported npm protection as OK on a machine with no npm
installed. Two compounding defects:
1. The availability gate used a plain `exec.LookPath`, which resolves the PMG
shim on PATH rather than the real binary, so the "skip" branch never fired.
It now uses `shim.ResolveRealBinary` (PATH with shim dirs stripped), matching
the runner, so a missing real binary correctly yields WARN "not available".
2. The result was inferred purely from a non-zero exit, so PackageManagerNotFound
(exit 127) and other failures were misread as a successful block. The check
now requires PMG's block headline in the captured output before reporting
PASS; other non-zero exits report WARN with the error surfaced.
The block headline is extracted into `ui.MalwareBlockedHeadline` so the doctor's
marker stays in sync with what PMG prints across its block-output sites.
* docs(specs): add custom block messages and package blocklist spec
* docs(specs): add custom block messages and package blocklist implementation plan
* feat(config): add blocked_packages list and custom block messages
* feat(audit): add package_blocklist_blocked event and blocklist model
* feat(proxy): block blocklisted packages in the policy gate before analysis
* feat(guard): block blocklisted packages before trust skip and analysis
* feat(ui): render blocklist blocks and custom messages, fix silent-mode block output
* feat(proxy): append custom messages to malware and go-cooldown block bodies
* test(proxye2e): cover blocklist enforcement and custom block messages
* docs(specs): remove spec and plan documents
* refactor: drop guard-flow blocklist enforcement and trim docs
Guard mode is being deprecated; the blocklist is enforced in proxy mode
only. Remove the trusted_packages mirroring references outside the docs.
* refactor(config): consolidate blocklist and block message under top-level block section
Replace dependency_cooldown.message, malware.message and blocked_packages
with a single block section: block.message is appended to every block
output regardless of which control blocked, and block.packages is the
package blocklist.
* fix(ui): render block.message as info note with clean spacing
* fix(ui): indent wrapped continuation lines in block reasons and messages
* update config template
* refactor(config): replace block section with top-level advisory_message
Remove the package blocklist (will be implemented as part of policies in
the future) and replace block.message with an optional top-level
advisory_message appended to every block output.
* chore(config): move advisory_message near top-level scalar configs in template
* feat: Add dependency cooldown for npm packages
Strip recently-published package versions from npm registry metadata
responses so npm's resolver naturally falls back to older versions.
Overrides the Accept header to force full packument responses (which
include the "time" field needed for publish-date checks).
Reports cooldown blocks only when all versions are stripped (remaining == 0),
matching npm's --min-release-age behavior for silent fallback.
* fix: Report oldest version in cooldown block (shortest wait)
When all versions are blocked by cooldown, report the oldest version
since it exits the cooldown window first — giving the user the
shortest wait time instead of the longest.
* fix: Handle resp.Body.Close error return for errcheck linter
* test: Add dependency cooldown assertions to template config tests
* fix: config template for dependency cooldown
* fix: Prevent npm from caching cooldown-stripped metadata responses
* fix: Restore body on ReadAll failure and log Close errors in response modifier
* fix: Close response body before replacing to prevent connection leak
* fix: Correct daysLeft ceiling math and update ContentLength on error recovery
* fix: Clear Status on status code change and update ContentLength in modifier error path
* refactor: address review comments on dependency cooldown PR
- Make NpmCooldownHandler and constructor package-private
- Pass cooldown days as parameter instead of reading config internally
- Convert standalone functions to methods on npmCooldownHandler
- Set Accept-Encoding: identity to prevent gzip responses breaking JSON parsing
- Return 503 with descriptive message when upstream body read fails
* fix: log errors in stripCooldownVersions instead of swallowing them
* fix: Config preserve fallback defaults
* fix: Code review fixes
* fix: correct cooldown tip to show wait time instead of incorrect trusted_packages advice
* fix: prevent integer overflow in cooldown duration calculation with large days values
* refactor: deduplicate CooldownBlock into internal/models, fix misleading variable names
- Move CooldownBlock struct to internal/models to eliminate duplication
between proxy/interceptors and internal/ui packages
- Simplify proxy_flow.go by using direct assignment instead of field copy
- Rename latestStripped/latestDate to oldestVer/oldestDate for clarity
* fix: Dependency Cooldown Check Encapsulation (#207)
* fix: Encapsulate cooldown check
* feat: Add --skip-dependency-cooldown override
* fix: Code review fixes

The spinner goroutine was writing carriage-return + status text to
os.Stdout every 100ms. In the non-interactive TTY path, the child
process also writes directly to os.Stdout, causing both writers to
race on the same file descriptor. The \r emitted by the spinner
resets the cursor to column 0 mid-line, corrupting and truncating
the child process output.
Fix by writing all spinner/status output to os.Stderr, which is the
standard Unix convention for diagnostic and status messages. This is
also consistent with how progress.go and ShowWarning already behave.
