Lab #3618: install.ps1 keeps the release zip until exit and deletes the old swamp.exe before copying the new one

Problem

Follow-up to swamp-club#3515 (swamp PR https://github.com/swamp-club/swamp/pull/3194, 44343a9e), which made install.sh delete the release archive as soon as the binary is extracted. scripts/install.ps1 has the same pattern and one more problem.

The archive stays on disk until the end. install.ps1 downloads swamp.zip into a temp dir, extracts it into extract, then copies the binary into place (Install-Binary, Copy-Item, around line 318). The temp dir is only removed in the final finally (around line 499). So a fresh install peaks at the zip, plus the extracted binary, plus the installed copy.
The old binary is deleted before the new one is copied. Install-Binary runs Remove-Item $destFile -Force and then Copy-Item (around lines 315–318).
- If the copy fails (disk full, AV quarantine, a permissions error), the user has no swamp at all.
- If swamp.exe is running, Windows locks it, so the delete fails and an upgrade over a running swamp can't complete.

Expected

As in #3515: delete swamp.zip and its .sha256 once they've been verified and extracted. Output, flags and exit codes stay the same.
Never leave the destination without a working swamp.exe. Copy or move the new binary next to the old one, then replace it. When the old binary is locked, rename it aside (Windows allows renaming a running exe) and clean it up on the next install or update. Report a clear error if the replace can't complete, rather than leaving no binary.
Check whether swamp update on Windows replaces the binary the same way. Report only.

Notes

#3515 rejected moving the binary into place for install.sh because of root-run installs writing into the destination directory. Windows installs are per-user by default, so check whether that reasoning applies here.

Extension scoring audits v2 archives exact-only and charges unaudited code, in the package and the CLI alike

extension fmt (and any command) creates or rewrites deno.lock when the extension lives in the repo's loaded extensions/ dir

extension quality: a collective-attested private repository scores provisional, and --json omits ifProvisionalEarned

Extension push ships the canonical form: every npm:/jsr: import pinned exact, and a v2 dependency-audit.json

judgeRunRecord lets a forged record settle a waiting approval gate to skipped without an approve

Extension dependencies: the shared import scan reads Babel syntax, not tokens (follow-up to #3969)

swamp-extensions: use explicit npm:/jsr: specifiers in root extensions/models

Five Mongo queues can hand the same row to two replicas

Registry rescore: secret-safe-docs passes a secret README line on versions whose stored metadata predates the sensitive flag (follow-up to #3783)

Score extensions with @swamp-club/extension-scoring (rubric v5) instead of the registry's own copy

Move the Zod argument-field extractor into @swamp-club/extension-scoring so the CLI and registry read schemas alike

Extension dependencies: one resolver for push, quality and fmt (no behaviour change)

Docs: extension quality scores with the registry formula and reports grade (swamp-club#3845)

Rescore every extension's current version under rubric v5

extension push: a swamp-quality-ignore directive after a comment holding an apostrophe is silently ignored

Share the extension quality rubric between the swamp CLI and swamp-club instead of mirroring it

Registry audits v2 extension archives as written, and a range costs the loose point only without a valid lock

Extension consumers keep the publisher's bundle: pull, update and auto-resolve stop rebuilding (direction A for #3634)

Extension push: inputs that open up (workspace root lock, ancestor config refused by name, JSR dist-tags) and the skill docs rewritten once

extension push (package.json mode): two installed copies under one declared range are audited once, so the second shipped version goes unaudited

Registry scorecard: score secret-safe-docs (rubric v4) and keep sensitive on extracted arguments

Registry dependency audit: audit the locked version push records in the archive, not the registry's newest match for a range specifier (swamp-club half of #3662)

stagecraft: rename work mode `method` to `behavior`, matching swamp's rename of models to behaviors

extension push: record each dependency's audited (locked) version in the archive, so the registry audits what ships (swamp half; registry half #3778)

main fails type check: query_view_test.ts passes a namespace string where expressionQueryView now takes a NamespaceReader (semantic conflict between #3790 and #3785)

forEachNameWithoutSecrets property test fails intermittently: an empty-string secret and an overlapping recorded value give different names

extension push finds no local modules when a folder above the repo is named node_modules

extension push (package.json mode): audit dependencies resolved through package.json, and leave the author's node_modules/ unchanged (merges #3632)

Local verification docs still tell agents to put ANTHROPIC_API_KEY in verify.env for reviews

@swamp/cve/php-rce-2026-10 follow-ups: dry-run heading, command spelling, Debian 12 fix, podman image scan

extension push resolves the Deno config and import map the way Deno does: deno.jsonc, importMap file references and scopes

extension fmt --check writes deno.lock in deno.json mode, which push and quality then bundle against with --frozen

@swamp/cve/dirtyfrag: scan logs are never saved (file writer handle dropped, data name collides with the status resource)

audit_deps.ts skips cve/ extensions, so their deno.lock files are never dependency-audited

@swamp/cve/dirtyfrag README shows --input targetHost/sshUser/sshKey/dockerContainer, which the CLI rejects

@swamp/cve/dirtyfrag mitigate uses interactive sudo, so it can hang on a password prompt or fail mid-run

extension quality names the wrong cause: a bundle failure prints no reason, the not-audited row always blames an outage, and symbols-docs blames JSDoc when deno doc failed

Docs: extension fmt never writes deno.lock and warns on a stale one (swamp-club#3717)

Docs: extension dependency trust pages — import-map auditing, bare-import rewrite and scoring, and the clarified warning/error plan
