Closes #1700

Summary

  • Adds a local-browser installation wizard that takes a clean Windows, macOS or Linux machine to a working gentle-shell without manual dependency installation.
  • Native bootstraps acquire integrity-verified Node.js and pnpm, then a 127.0.0.1-only wizard shows the exact plan (including shell profile and PATH changes) and asks for one explicit consent.
  • Installs Pi and Gentle Shell globally with pnpm, persists Node/npm/pnpm under $PNPM_HOME only when missing, and runs the existing gentle-shell setup instead of duplicating companion installation.

  • New feature

How it works

Layer Files Notes
Preflight scripts/installer-preflight.mjs Read-only inventory and ordered plan.
POSIX bootstrap scripts/bootstrap.sh, scripts/installer-downloads.mjs Pinned, SHA-verified Node 24.21.0 and pnpm 11.1.1 in an owned temp dir, removed after success.
Windows bootstrap scripts/bootstrap.cmd, scripts/installer-windows.mjs, scripts/installer-windows-artifacts.json Fixed CMD entry, ACL/reparse checks, no unsigned .ps1, reparse-safe cleanup.
Host probes scripts/installer-probes.mjs Real read-only probes with deadlines and bounded output.
Runner scripts/installer-runner.mjs Fixed argv only; --allow-build=gentle-pi (never blanket); genuine-npm and Windows Go gates; existing-stack block; never ready on skipped or unverified steps.
Local host scripts/installer-server.mjs, bin/gentle-shell-install.mjs Loopback only, exact Host, one-time code via a private 0600 redirect file, HttpOnly SameSite=Strict cookie, Origin + custom header, strict CSP, server-side plan with re-inventory.
UI assets/install-wizard/* Accessible, keyboard-only flow, gentlemanprogramming.com visual language, no external resources.
Acceptance and CI scripts/test-installer-acceptance.sh, .github/workflows/ci.yml Opt-in disposable Docker run; new installer job on ubuntu, macOS and Windows that requires the 14 native Windows tests to actually run.

Full design, contracts and remaining checks: docs/install-wizard.md. Task ledger: odd/tasks/browser-install-wizard.md.

Review notes

This is one PR by choice (about 11k lines; roughly 3k are CSS with one property per line, and a large share is tests). It is built from 15 work-unit commits; each feature commit was independently verified and natively reviewed before it was made, so reviewing commit by commit is the easiest path.

Test plan

  • Installer suites: node --experimental-strip-types --test over the 8 installer test files → 246 tests, 232 pass, 0 fail, 14 skipped (native Windows tests, unavailable on Linux).
  • node scripts/verify-package-files.mjs → passed (168 files).
  • sh -n on both shell scripts; actionlint clean on ci.yml; shellcheck clean on the acceptance script (bootstrap.sh keeps four findings that already exist on main).
  • Real clean-machine acceptance on Linux: disposable debian:bookworm-slim container with no Node/npm/pnpm/Pi → all 13 runner steps done, bootstrap exit 0, a new bash -i resolves node 24.21.0, npm 11.19.0, pnpm 11.1.1 and gentle-shell --version 4.0.0, and the bootstrap tools are removed.
  • Headless Chromium checks of every wizard state at 1440px and 390px with zero CSP violations.
  • Native Windows and macOS: first evidence comes from this PR's installer CI matrix.
  • Real browsers, screen readers, zsh/fish and other distros.

Known limitations

  • pnpm setup writes only the interactive shell profile, so non-interactive shells (bash -lc, cron) need $PNPM_HOME/bin added manually; documented.
  • Upstream Gentle AI resolves the latest Engram version through the anonymous GitHub API (60 requests/hour per IP). When that limit is hit, the wizard now shows the real error and specific guidance.

Checklist

📝 Walkthrough

Walkthrough

This pull request adds a browser-based installation flow with host checks, platform-specific bootstraps, consent-gated installation, local server and UI components, and test and documentation coverage. It adds CI jobs for installer tests and a Linux container acceptance script.

Changes

Installer flow

Layer / File(s) Summary
Host inventory and preflight planning
scripts/installer-probes.mjs, scripts/installer-preflight.mjs, tests/installer-probes.test.ts, tests/installer-preflight.test.ts, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
Host probes collect bounded evidence for installed tools and setup state. Preflight planning classifies that evidence and produces ordered actions or blockers. Tests cover supported targets, probe outcomes, and persistence action selection.
Cross-platform bootstrap and tool acquisition
scripts/bootstrap.sh, scripts/bootstrap.cmd, scripts/installer-downloads.mjs, scripts/installer-windows.mjs, scripts/installer-windows-artifacts.json, tests/installer-posix-bootstrap.test.ts, tests/installer-windows-bootstrap.test.ts, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
POSIX and Windows bootstrap paths validate prerequisites and storage, acquire pinned tools when needed, verify artifacts, and limit cleanup to owned locations. Tests cover acquisition, archive validation, and cleanup behavior.
Consent-gated installation and persistence
scripts/installer-runner.mjs, tests/installer-runner.test.ts, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
The runner validates consent and supported plans, applies fixed persistence and package-install steps, verifies installed tools, and reports ready, terminal-action-required, or failure outcomes.
Local server and installer entry point
bin/gentle-shell-install.mjs, scripts/installer-server.mjs, tests/installer-server.test.ts, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
The entry point starts the loopback server and connects preflight and installation. The server handles one-time session redemption, request checks, plan validation, and progress and outcome responses.
Browser wizard and preview
assets/install-wizard/*, scripts/install-wizard-preview.mjs, tests/install-wizard.test.ts, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
The browser UI renders plan, progress, and outcome screens and manages consent, requests, and polling. A preview tool serves simulated plans and outcomes through the installer host.
Packaging, acceptance, and platform checks
.github/workflows/ci.yml, scripts/test-installer-acceptance.sh, scripts/verify-package-files.mjs, tests/verify-package-files.test.ts, README.md, docs/install-wizard.md, odd/tasks/browser-install-wizard.md
Package verification includes wizard resources. CI runs installer tests on Ubuntu, macOS, and Windows, with an additional native Windows test condition. The acceptance script exercises bootstrap and installation in a disposable Debian container.

Merge Risk: ⚪ Minimal · up to 6c593

No demonstrated issue blocks merging on the available evidence. Native Windows validation for this revision remains pending.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 6c593

Local-access controls, explicit consent and fixed installation commands substantially limit exposure. However, interruption and timeout handling do not ensure all launched installation work has stopped, which can leave persistent changes in flight when recovery begins.

Retained concerns

  • Medium · reliability · inferred: The new installation lifecycle can report failure or close before launched work is contained. Deadlines signal only the direct child and settle without waiting for termination; signal shutdown exits without joining active installation work. Descendant package or setup processes may retain the invoking user's authority and continue persistent writes after the per-run lock disappears, allowing recovery to observe or overlap an unfinished transition. This is an inferred failure-containment risk, not a demonstrated remote compromise.
Security review details

Security Blast Radius

  • inferred — The sensitive scope is the invoking user's machine: persistent runtimes, global packages, npm configuration and shell profile or user PATH changes. No elevation mechanism is established by the inspected flow. Launched descendants inherit the installation environment and can retain that user's authority after their parent terminates.

Security Findings and Attack Paths

  • inferred — No remote installation-control bypass was established in the inspected source. The retained architecture concern is instead an interruption path: direct-child timeout or wizard signal shutdown may leave descendant mutations running, and a subsequent wizard has no demonstrated coordination with that unfinished work.

Trust Boundaries and Controls

  • observed — A random expiring one-use code establishes a session cookie with HttpOnly and SameSite=Strict. Requests require the exact Host; APIs require a custom header, and mutations additionally require the exact Origin and JSON content type. Fixed routes, fixed asset names and restrictive browser headers constrain web-origin access to the local execution authority.
  • observed — Windows success cleanup uses Directory.Delete after checking root identity and its ownership marker, while failure cleanup uses recursive Remove-Item. The differing primitives leave concurrent-substitution behavior unproved, but the storage ACLs exclude untrusted mutation and the documented threat model excludes malicious same-principal processes; an attacker-reachable deletion finding is therefore not established.

Resilience and Maintainability Implications

  • observed — The process adapter deliberately releases pipes and returns at the deadline rather than awaiting process closure. Tests verify that bounded return even when the child never closes; this protects host responsiveness but does not establish termination of the installation process tree or completion of its persistent writes.

Hardening Proposals

  • proposed — Give mutating installation work an explicit cancellation and ownership lifecycle, using platform-appropriate process-tree containment. Keep recovery from overlapping uncertain in-flight work, and report partial changes accurately when termination cannot be confirmed.
  • proposed — Use a consistent reparse-safe cleanup strategy on Windows success and failure paths, and validate interruption and concurrent mutation within the supported threat model. This is hardening, not an observed deletion exploit.

Explanation

[#1700] The PR implements the installer and reports successful Linux clean-machine acceptance. It also addresses the reported PATH, setup-recovery, and timeout issues. The task ledger still lists native Windows and macOS acceptance as open. The installer CI matrix runs tests, but the available evidence does not show a clean-machine install reaching a working gentle-shell on either platform. This leaves the proposed Windows/macOS support unverified.

Review comments at @docs/install-wizard.md:
- Around line 634-638: Update the installation-wizard documentation to describe
bin/gentle-shell-install.mjs as the current entry, removing stale claims that it

scripts/bootstrap.sh reports missing required bundle components before downloads
or home writes, rather than always stopping before acquisition.

Review comments at @scripts/installer-runner.mjs:
- Around line 571-573: Update the `persist-path` step to use the install-class
`deadlines.setup` deadline, or an equivalent dedicated setup deadline, instead
of `deadlines.probe` while running `pnpm setup`. Update the documented 30-second
timeout for `pnpm setup` to match.

Review comments at @scripts/installer-server.mjs:
- Around line 386-394: Update the background promise chain around runInstall and
outcomeView so an outcomeView failure is handled without leaving the server in a
rejected-promise state. Ensure installing is reset and lastActivity updated in a
finally path regardless of success or failure, while preserving the existing
outcome behavior where possible.

Review comments at @scripts/installer-windows.mjs:
- Around line 184-185: Update findWindowsCommand to skip empty entries when
iterating Windows PATH directories, while retaining the fail-closed checks for
relative or quoted entries; add a portable test that calls ensureWindowsPnpm
without a findCommand override using Path set to a value with a trailing

I would address these three functional issues before merging (reviewed at c356846):

  1. [P1] Empty Windows PATH entries abort missing-pnpm acquisition. In scripts/installer-windows.mjs:184–185, a trailing ; produces an empty directory and throws Unknown Windows PATH. With no existing pnpm, the bootstrap fails instead of acquiring it. I reproduced the resolver branch with Windows path semantics: C:\Windows returns no command, while C:\Windows; throws. Skip empty entries while retaining rejection of unsafe nonempty paths.

  2. [P2] A failed setup strands a partial installation without wizard recovery. In scripts/installer-runner.mjs:557–579, gentle-shell setup runs before PATH persistence. If setup fails, for example due to GitHub rate limiting, the global packages remain installed but their commands may still be absent from the user PATH. Reopening the wizard then produces unknown-tool: setup with no actions; the runner also rejects an existing stack. The guidance to rerun the installer cannot complete this state. Please add an explicit recovery path for partial installations that completes setup/PATH without reinstalling or overwriting existing packages.

  3. [P2] The pnpm setup timeout is too short for its network work. At scripts/installer-runner.mjs:573, it uses the 30-second probe deadline, although docs/install-wizard.md records that pnpm 11.1.1 installs @pnpm/exe over the network before updating PATH. A slow connection can fail an otherwise completed installation. Use an install/setup-class deadline and update the timeout contract/tests.

Validation: the Linux installer suites passed locally (232 passed, 14 native Windows tests skipped). CI run 37109363955 still fails on macOS, Windows, and typecheck: macOS fixtures use noncanonical /var temporary paths; Windows native fixtures fail in their cleanup guard, and the writability test assumes POSIX chmod semantics; typecheck introduces TS2345 and TS2561 diagnostics. These checks need to pass before relying on the cross-platform installation claims.

Thanks @egdev6, all three were real. Fixed in 81b420c and 29ae994:

  1. Empty Windows PATH entries: the resolver now skips exactly empty entries (trailing ;, ;;) and still rejects relative, quoted and UNC entries. Covered by a portable test.
  2. Partial installation recovery: rerunning the wizard on a stack that is exactly the pinned Pi and gentle-pi versions, in one pnpm global project under $PNPM_HOME, now offers "Complete setup". It only runs gentle-shell setup (plus pnpm setup when the bin dir is off PATH) and re-verifies the stack first. It never runs add -g. Foreign or other-version stacks stay blocked, and a stack that changes between plan and run blocks with existing-stack-unverified. Details in the "Setup recovery" section of docs/install-wizard.md.
  3. pnpm setup deadline: persist-path now uses the 20-minute setup deadline, with a test pinning it.

On CI: the macOS failures were fixture paths (/var vs /private/var), not the guard, which stays as is. The Windows probe test no longer assumes POSIX chmod, the native fixture guard now ends with an explicit exit 0 and prints PowerShell's stderr if it still fails, and the typecheck diagnostics are fixed without touching the baseline. CI is rerunning; I'll follow up with the native Windows results.

Follow-up on native Windows: CI is fully green on 5ed499a, including the installer (windows-latest) job with all 14 native Windows tests executed (0 skipped).

Getting there surfaced three real Windows bugs, now fixed in production:

  1. Get-Acl under a PowerShell 7 parent: Windows PowerShell 5.1 could not autoload Microsoft.PowerShell.Security when launched from pwsh, so the ownership claim failed. ACLs are now read and written through .NET (GetAccessControl/SetAccessControl) with the same checks.
  2. Non-ASCII profile paths: .node-target was written as BOM-less UTF-8 and read back as ANSI, corrupting paths like C:\Users\José. It is now written and read as explicit UTF-8.
  3. .CPL in PATHEXT: Windows PowerShell appends .CPL, which the pnpm resolver rejected for every run. It is now recognized but never accepted as a candidate, so a .cpl shadowing the real command still fails closed.

The bootstrap stages also report a fixed Reason: code on failure (unexpected errors as unexpected-<step>), so future native failures point at the exact check.
