Pull request overview
This PR implements post-audit hardening across the CLI lifecycle pipeline: safer mirror writes, guarded external HTTP reads, stricter CLI option parsing, and behavioral tweaks to make mutating operations more explicit—along with regression tests and documentation updates.
Changes:
- Add guarded HTTP utilities (origin allowlists, timeouts, byte limits) and apply them to official-index, GitHub raw reads, and registry metadata fetches.
- Harden filesystem writes for mirrored multi-file artifacts via safe path resolution to prevent traversal outside the raw mirror root.
- Centralize CLI option parsing (reject missing/flag-like values) and adjust lifecycle orchestration (explicit
recommend report, preview-by-default wire intent), with accompanying tests/docs.

61-79:⚠️ Potential issue | 🔴 Critical | ⚡ Quick win
--applyis silently treated as--preview— critical regression.
--applyis included inmodeFlagsfor conflict detection but has no explicitreturn "apply"branch. Before this PR, falling through to the defaultreturn "apply"made it work by coincidence. Now that the default was changed toreturn "preview", any invocation ofwire <host> --applyquietly produces preview-only behaviour: no host settings are mutated, no error is raised, and the caller has no indication that the apply was skipped.🐛 Proposed fix

98-101: ⚡ Quick winStack trace is suppressed for all
Errorinstances — consider preserving it for unexpected failures.
error instanceof Error ? error.message : errorstrips the stack trace for everyError, including unexpected internal errors (I/O failures, assertion violations, etc.). User-facing CLI errors like "Missing value for '--host'." read fine, but a buggy code path would only surface its message with no location.The existing
console.error(error)call in Node.js already prints the message prominently at the top, followed by the stack — which is the best of both worlds.♻️ Proposed alternatives
Option A — restore full error output (simplest):
- console.error(error instanceof Error ? error.message : error); + console.error(error);Option B — clean output by default, stack on
--debug:- console.error(error instanceof Error ? error.message : error); + const debug = process.argv.includes("--debug"); + console.error(error instanceof Error && !debug ? error.message : error);🤖 Prompt for AI Agents

Inline comments:
In `@src/discover.ts`:
- Around line 472-490: The per-source status logic now distinguishes
"reference-only" (has catalog entries but no operational entries) from "dormant"
(no entries), but the aggregate dormantSourceCount still counts every
non-operational source; update the dormantSourceCount calculation to match the
per-source status by counting only sources with zero catalog entries (i.e.,
sourceEntries.length === 0) rather than all non-operational ones. Locate the
block that builds sources (the enabledSources.map producing
id/kind/configured/operational/harvestedEntries/operationalEntries/status) and
ensure the dormantSourceCount computation uses the same criteria (check
sourceEntries.length) so that dormantSourceCount only increments when a source's
status === "dormant".
In `@src/lib/http.ts`:
- Around line 17-29: fetchWithTimeout currently overwrites any caller-provided
options.signal, preventing upstream cancellation; modify fetchWithTimeout to
preserve and merge the incoming options.signal with the timeout AbortController
(e.g., create a timeout controller and if options.signal exists use
AbortSignal.any([options.signal, timeoutController.signal]) for the final signal
or attach a listener that aborts the timeout controller when options.signal
fires), pass that merged signal into fetch, and ensure you still clear the
timeout and remove any listeners in the finally block so no leaks occur; update
references in fetchWithTimeout to use the merged signal instead of directly
using controller.signal.
In `@src/package-registries.ts`:
- Around line 120-139: Normalize and validate PyPI URL fields before storing:
when building the returned info object in package-registries (fields
info.home_page and info.project_urls via normalizeStringRecord), parse each URL
string and only keep values that are valid absolute URLs with scheme "http" or
"https" and a non-empty host; otherwise set home_page to undefined and
drop/replace invalid project_urls entries. Update normalizeStringRecord (or its
caller) to perform this filtering/normalization so downstream functions like
extractRepositoryUrlFromPypiMetadata only see bona fide http(s) URLs; apply the
same validation logic to the other similar block that constructs
info.project_urls/info.home_page later in the file (the block referenced in the
review).
