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.

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.

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.

Tested the wizard on macOS, and it worked end to end. One caveat on what "clean" means here, see below.

Environment: macOS 26.5.2 (25F84), Apple Silicon (arm64), zsh. The machine has Node via Homebrew and fnm (v24.19.0), but both are loaded from ~/.zprofile/~/.zshrc. I launched sh scripts/bootstrap.sh (branch tarball at 5ed499ad) over a non-interactive SSH session, so the bootstrap saw no Node, npm or pnpm. Effectively this exercised the clean-machine path: Node 24.21.0 and pnpm 11.1.1 acquired, then persisted under $PNPM_HOME.

Result:

  • The browser opened on the Mac, I consented, and it finished in about 2.5 minutes with "Open a new terminal so it picks up the updated PATH".
  • Right after install, pnpm list -g showed exactly @earendil-works/pi-coding-agent@1.0.0 and gentle-pi@4.0.0 plus the persisted runtime. gentle-shell --version reported 4.0.0 with the isolated home ~/.gentle-shell/agent.
  • ~/.gentle-shell-bootstrap-tools.* was removed after success.
  • pnpm setup appended only the # pnpm block to ~/.zshrc (PNPM_HOME=~/Library/pnpm). ~/.zprofile was untouched, and the empty ~/.pi/gentle-ai was created as documented.
  • In a real login + interactive zsh, gentle-shell and pnpm resolve from ~/Library/pnpm/bin, and the user's fnm Node still wins over the persisted one.
  • After install, logging in and running a session through gentle-shell worked, including Engram memory.

Observations:

  1. Runtime persistence is decided from the launcher's environment. A user whose Node only exists in their interactive profile (fnm, nvm, brew via .zprofile) ends up with a second, persisted Node under $PNPM_HOME. That's harmless here, but it may be worth a line in the docs: run the bootstrap from a normal terminal.
  2. As documented for bash, a non-interactive login shell (zsh -lc) does not resolve gentle-shell. The ~/.profile note maps to ~/.zprofile on macOS, so it might be worth naming zsh explicitly.

Not tested: the "Node present, pnpm missing" path from a regular terminal, real screen readers, and fish.

Testing commit 5ed499ade6c93733990e0298052df477428a90be on macOS 26.7.1 (uname -m: x86_64), using a sandbox account with a restricted PATH, the bootstrap stops before downloading Node or opening the wizard:

Bootstrap: Unsafe tooling ownership

The bootstrap file’s SHA-256 matches that commit. The temporary directory belongs to the current UID, has permissions 700, and shows no ACL entries. Its only listed extended attribute is com.apple.provenance, so macOS renders its mode as drwx------@.

In scripts/bootstrap.sh:79, the owner comparison passes, but $1 == "drwx------" fails because of the trailing @.

Could this validation avoid relying on the rendered ls mode string while preserving ownership, permission and ACL checks, with a macOS regression test covering this case?

Tested 5ed499a on Windows 11 x64, a domain-joined machine with a local admin account, in PowerShell 5.1. Before the test I removed the previous npm i -g gentle-pi install. It ended up working, after hitting three issues.

1. nvm-windows Node is rejected (parent-reparse)
With Node 24.21.0 managed by nvm-windows, the bootstrap stops before acquisition:
Bootstrap: Node version, execution, deadline, output bound or policy check failed; refusing replacement. Reason: parent-reparse
nvm-windows exposes Node through a junction (C:\nvm4w\nodejs → %LOCALAPPDATA%\nvm\v24.21.0), so every nvm-windows user is blocked. Workaround: nvm off, after which the bootstrap acquires its own Node. A clearer message, or explicit support for the nvm junction, would help.

2. gentle-shell setup fails with spawn EPERM when gentle-ai.exe cannot execute
The run failed at step 12/13 (shell-setup), and the wizard only showed spawn EPERM. With NODE_DEBUG=child_process, the failing spawn is the package-local ...\gentle-pi\.gentle-ai\v4.0.0\gentle-ai.exe, which is unsigned (NotSigned). Running it directly gave "Access denied" even after copying it elsewhere. File ACLs were fine (full control), and there were no Defender ASR, AppLocker, WDAC or SRP block events. Our IT team allowed the binary in the endpoint security console; no policy change was needed. After that, setup worked. This looks related to gentle-ai#987 (unsigned Windows binaries blocked by application control). Suggestion: detect a spawn EPERM/EACCES on gentle-ai.exe and report it as "Windows blocked gentle-ai.exe, likely by a security policy", rather than a raw spawn EPERM.

3. Recovery after the failure
Because shell-setup runs before persist-path, the failed run left the packages installed but pnpm\bin off the user PATH. Rerunning the wizard completed the remaining steps (8 steps), and gentle-shell --version then reported 4.0.0 / pi 1.0.2 with the isolated home. Recovery works. 👍

  • An existing global pnpm 12.4.1 (installed via npm) is not reused: the wizard bootstraps 11.1.1 and persists node/npm/pnpm under PNPM_HOME. It also points npm's global prefix at PNPM_HOME, which affects later npm i -g once nvm is turned back on. It might be worth calling this out for nvm users.
  • The "open a new terminal" step is not enough inside the VS Code integrated terminal: VS Code itself has to be restarted to pick up the new PATH.
  • Starting gentle-shell from C:\WINDOWS\System32 (the default directory of an elevated PowerShell) logs Skill registry refresh failed: EPERM ... mkdir 'C:\WINDOWS\System32\.atl'. This is harmless, but a friendlier hint would help.

Prueba real en Windows limpio — resultado: FAIL con varios P1/P2 candidatos

Probé el PR #1703 sobre el commit exacto
5ed499ade6c93733990e0298052df477428a90be.

Antes de probarlo leí el hilo completo. Vi que los tres problemas reportados por egdev6
(PATH vacío, recuperación de setup y timeout de pnpm setup) ya se marcaron como corregidos,
que el CI nativo de Windows pasó 14/14 en este commit y que dcozargrafia completó el flujo en
macOS. También revisé los reportes posteriores de restevean y pmNiko: no repito aquí sus
casos de macOS, nvm-windows ni bloqueo del binario sin firma. Lo siguiente es evidencia
adicional de una máquina Windows física limpia; no pretende reabrir puntos ya corregidos.

Entorno

  • Windows 11 Home 25H2 x64, build 26200.9457.
  • Sesión no elevada, Chrome y Windows PowerShell 5.1 como perfil habitual.
  • LongPathsEnabled=0.
  • Política efectiva de Windows PowerShell: Restricted (todos los scopes sin configurar).
  • Estado inicial real: sin Node, npm, pnpm, Git, Go, Pi ni Gentle Shell en el PATH del usuario.

La instalación final solo pudo completarse instalando Go y Git manualmente y usando un
PNPM_HOME corto (%USERPROFILE%\gs\pnpm). El happy path del wizard no terminó por sí solo.

[P1 candidato] Los comandos instalados no funcionan por nombre en PowerShell 5.1 limpio

Después de instalar, CMD funciona, pero una ventana nueva de Windows PowerShell 5.1 resuelve
primero los shims .ps1 y los bloquea con la política predeterminada Restricted:

npm : No se puede cargar ...\npm.ps1 porque la ejecución de scripts está deshabilitada
pi : No se puede cargar ...\pi.ps1 porque la ejecución de scripts está deshabilitada
gentle-shell : No se puede cargar ...\gentle-shell.ps1 porque la ejecución de scripts está deshabilitada

npm.cmd, pi.cmd y gentle-shell.cmd sí funcionan.

Esperado: los comandos mostrados por el instalador funcionan en una terminal nueva sin
cambiar una política de seguridad del sistema.
Frecuencia: 1/1 en PowerShell 5.1; CMD 1/1 correcto.
Workaround: usar CMD o invocar explícitamente los .cmd.

[P1 candidato] Review promete instalar Go, pero el runner bloquea ese mismo plan

Con Go ausente, Review mostró:

Download a verified Go toolchain.
Check that the Go toolchain runs.

Después del consentimiento terminó en go-required:

Windows needs Go 1.25.10 or newer on PATH.
Install Go, then run installer again.

Esperado: ejecutar las acciones revisadas y aceptadas.
Actual: el preflight emite acquire-go, pero el runner rechaza ese plan en Windows.
Frecuencia: 1/1 y parece determinista por código.
Workaround: instalé Go 1.27.0 manualmente y verifiqué su SHA-256 oficial.

[P1 candidato] El pin de Pi 1.0.0 no es el runtime que usa Gentle Shell

El plan instala @earendil-works/pi-coding-agent@1.0.0 y la lista global confirma ese pin:

pi --version                         -> 1.0.0
pnpm list -g                         -> pi-coding-agent 1.0.0
gentle-shell --version               -> pi 1.0.2

El proyecto global de gentle-pi@4.0.0 resolvió automáticamente su peer a
@earendil-works/pi-coding-agent@1.0.2, separado del paquete global fijado. El launcher usa
ese peer adyacente 1.0.2.

pmNiko también observó gentle-shell --version con Pi 1.0.2. En esta máquina pude confirmar
además que pnpm creó proyectos globales separados y que esa resolución del peer es la causa.

Esperado: que el runtime ejecutado sea el mismo Pi 1.0.0 que el plan muestra y verifica.
Riesgo: la instalación no es reproducible y puede ejecutar una versión publicada después
del commit/plan consentido.

[P1 candidato, específico de este PC] Un capability SID válido bloquea el bootstrap

Con %LOCALAPPDATA% normal, scripts\bootstrap.cmd terminó antes de abrir el wizard:

Bootstrap: private storage ACL/reparse/ownership claim failed or policy denied it.
Reason: acl-mask

El directorio pertenecía al usuario y era escribible. El rechazo lo provocó una ACE heredada
de un capability SID estándar de Windows/AppContainer (S-1-15-3-...) con FullControl.
Además, cinco pruebas nativas de Windows relacionadas con ACL fallaron por acl-mask.

Workaround: redirigir LOCALAPPDATA solo para el proceso a un directorio privado.
Cautela: puede depender de las aplicaciones instaladas en este equipo, pero es un bloqueo
real y el directorio no era inseguro ni ajeno al usuario.

[P1/P2 candidato] El build de Gentle AI falla cerca de MAX_PATH

Con un PNPM_HOME válido pero más largo, install-global falló 3/3. Capturando el stderr real
del go install:

golang.org/x/crypto/blake2b:
...\Go\pkg\tool\windows_amd64\asm.exe:
fork/exec ...\asm.exe: The directory name is invalid.

El cwd de staging tenía 205 caracteres y una ruta de módulo llegaba a 259 antes de añadir el
nombre de archivo. En este Windows LongPathsEnabled=0.

Control: el mismo build sellado y la misma versión exacta, con roots más cortos, terminó
correctamente. Con %USERPROFILE%\gs\pnpm, la instalación completa pasó 1/1.
Sugerencia: construir en un staging corto fuera del store o bloquear antes con una guía
específica basada en la longitud efectiva.

[P2] Los fallos de pnpm/Go pierden stderr y se etiquetan siempre como red

persist-node falló 2/2 en el wizard después de descargar Node. El error real era:

[ENOENT] ENOENT: no such file or directory, open
'...\global\v11\...\node_modules\node\package.json'

Quedaron store/proyecto parcial, pero no PNPM_HOME\bin\node.exe. Los reintentos inmediatos
repitieron el estado parcial. La UI solo mostró:

Installing Node.js under PNPM_HOME failed. Check your network connection.

Lo mismo ocurrió con el error de MAX_PATH de Gentle AI. Sería útil capturar un tail limitado,
sanitizar rutas y clasificar al menos ENOENT, EACCES/EPERM, timeout y fallo de toolchain.

Cautela: el ENOENT de Node parece relacionado con la combinación AppData/entorno Codex;
en un PNPM_HOME fuera de AppData el mismo comando exacto pasó. La pérdida del diagnóstico y la
ausencia de recuperación sí son independientes de esa causa.

[P2] Setup declara readiness aunque falta Git y reporta mal la ruta de Engram

En la primera ejecución:

WARNING: missing dependencies: git
Missing 1 required dependency(ies): git
...
Verification checks: 3 passed, 0 failed
You're ready. Start building.

También afirmó que Engram se instaló en %USERPROFILE%\go\bin, pero ese directorio no existía.
El binario real quedó en %LOCALAPPDATA%\engram\bin, que sí se añadió al PATH.

Esperado: una dependencia marcada como requerida impide declarar readiness completa, y la
ruta mostrada coincide con la ubicación real.
Workaround: instalé Git manualmente; el dry-run posterior detectó Git 2.55.0 correctamente.

[P2] Un padre PowerShell 7 todavía puede romper el bootstrap de Windows PowerShell 5.1

Al lanzar bootstrap.cmd desde pwsh 7, Windows PowerShell 5.1 heredó un PSModulePath que
apuntaba primero a módulos de PowerShell 7 y no pudo cargar Get-FileHash desde
Microsoft.PowerShell.Utility.

Vi en el hilo que ya se corrigió el caso equivalente de Get-Acl sustituyéndolo por .NET. Este
parece ser el mismo problema de compatibilidad en otro comando del bootstrap.

Workaround: limpiar PSModulePath solo para el proceso o ejecutar desde CMD.

[P2] Los intentos fallidos dejan aproximadamente 1,9 GiB sin recuperar

Después de los fallos quedaron stores/staging parciales en %LOCALAPPDATA% y en el directorio
de pruebas. El instalador avisa correctamente de que no hace rollback, pero no ofrece una ruta
de limpieza ni distingue qué restos son seguros de borrar. No eliminé nada automáticamente
para conservar la evidencia.

Qué sí funcionó

  • Servidor local, UI, revisión y consentimiento.
  • Node 24.21.0, npm 11.19.0 y pnpm 11.1.1 en un PNPM_HOME corto.
  • Pi 1.0.0, Gentle Shell 4.0.0, Gentle AI 4.0.0 y Engram 3.0.0.
  • gentle-shell setup: 3 verificaciones pasadas; segunda ejecución y --dry-run con exit 0.
  • CMD y los shims .cmd funcionan desde un proceso nuevo; PATH persistido sin duplicados.
  • node scripts/verify-package-files.mjs: 168 archivos y 69 artefactos exactos verificados.
  • Suite dirigida del instalador: 269 tests, 212 pasados, 6 fallidos y 51 omitidos. Cinco fallos
    fueron acl-mask; el otro fue EPERM al crear un symlink sin elevación.

No probado

  • Reinicio completo de Windows.
  • Inicio de sesión con un proveedor/modelo y una conversación real.
  • Windows ARM64, Narrator y pruebas destructivas de interrupción/rollback.

Gracias, Alan. Puedo separar cualquiera de estos hallazgos en un issue con el log sanitizado y
un repro mínimo si ayuda.

Tested 5ed499a on Linux: Ubuntu 22.04.5 LTS (x86_64, glibc 2.35), clean machine, real browser. Result: PASS end to end, plus one edge case worth knowing.

Environment: disposable ubuntu:22.04 Docker container with no Node/npm/pnpm, wizard opened in Chrome through an SSH -L tunnel (the Host check at scripts/installer-server.mjs:454 passes because the tunnel preserves the port). curl was the only pre-installed extra (bootstrap.sh:108 requires it).

Run 1, launched from a non-interactive context (no SHELL): Node 24.21.0 acquired, SHA-verified and executed in ~35s, consented in the browser, 12 of 13 steps green. Step 13 persist-path failed with pnpm setup returning [ERR_PNPM_UNKNOWN_SHELL] Could not infer shell type, surfaced with the persistPathShell guidance and no partial damage: the stack itself was fully persisted (`` bin/global/store with gentle-shell, `pi`, npm/npx shims, node as a pnpm global). This is the cron/CI/`docker exec` launch class. A preflight warning when `SHELL` is unset (before consent) might save those users a run.

Run 2, relaunched with SHELL=/bin/bash: the wizard detected the just-installed pinned stack and offered Complete setup (the recovery path from @egdev6's review): re-verified the stack, ran gentle-shell setup and pnpm setup, all checks green including PATH persistence. bootstrap.sh exited 0, removed its temp tooling ~10s after the wizard page closed, and a fresh bash -i resolves node 24.21.0, npm 11.19.0, pnpm 11.1.1 and gentle-shell --version 4.0.0.

Minor UX note for remote users: the URL is single-use, expires in 2 minutes, and the port changes every launch, so each retry over SSH needs a fresh tunnel. Workable, just fiddly; not a bug.
