fix: resolve the install from the running binary; make upgrade failures diagnosable (#1305) - #1306
Conversation
…es diagnosable (#1305) `Installation.method()` never established where the running executable came from. It guessed two ways, and both were unsound: - A substring test on `process.execPath`. `~/.local/bin` is a generic user bin dir, so an npm install with `npm config set prefix ~/.local` was classified `curl`, and `altimate upgrade` ran `curl | bash` — silently converting an npm install into a standalone one and leaving the npm copy orphaned on PATH. - A probe loop (`npm list -g`, `brew list`, ...) returning the first manager whose output mentioned the package. That answers "is this installed anywhere?", not "did THIS binary come from you", so it picked arbitrarily whenever several installs existed. Replaced with `resolveInstall()`, which resolves `realpath(process.execPath)` and matches the package segment. The npm `bin/altimate` shim `spawnSync()`s the per-platform package, so execPath always lands under `node_modules` for package-manager installs; the optional `-<platform>-<arch>` suffix is matched explicitly. Removes up to seven subprocess spawns from the startup update-check path. Added a writability preflight so an upgrade that cannot succeed is refused before shelling out, with a message naming the directory and the exact remedy. Uses `npm root -g` rather than `<prefix>/lib/node_modules`, which is Unix-only, and derives the bin dir from `npm prefix -g` because `npm bin -g` was removed in npm 9. Also fixed an asymmetry in the failure branch: the success path logged the real stdout/stderr while the failure path discarded them, so every non-permission failure (network, `E404`, `ENOSPC`, a failing lifecycle script) collapsed into an identical `Upgrade failed for npm (exit code N).` with nothing written anywhere. The real output is now logged locally, the message carries a classified hint plus a pointer to the log, and telemetry records a stable classification code instead of the generic string — previously every failed upgrade looked identical on a dashboard. The user-facing message and the telemetry payload stay redacted. Four existing tests asserted on the source text or the exact error string and were updated to track the new contract while preserving their intent (brand guard, redaction guards).

WARNING: Yarn-classic global installs on Windows are misclassified as npm
YARN_SEGMENT_RE matches .yarn/ and yarn/global/, but yarn v1's default global folder on Windows is %LOCALAPPDATA%\Yarn\config\global — after realpath the binary sits at ...\Yarn\config\global\node_modules\@altimateai\altimate-code-<platform>\bin\altimate-code.exe. That path satisfies PKG_SEGMENT_RE but none of the manager sub-checks, so resolveInstall() falls through to npm, and the upgrade path (including the startup auto-upgrade in src/cli/upgrade.ts:163) runs npm install -g @altimateai/altimate-code@<target> against a yarn install — silently creating a second, npm-managed binary that shadows it. That is exactly the orphaned-install scenario this PR set out to fix. The new table tests only cover the Unix ~/.yarn/global spelling.

WARNING: Every npm-layout path is treated as a global install — npx caches and project-local installs now silently trigger npm install -g
PKG_SEGMENT_RE matches any node_modules/@altimateai/altimate-code[-platform-arch] segment, not just package-manager global roots. ~/.npm/_npx/<hash>/node_modules/... (npx), a project-local node_modules (CLI as a devDependency), Volta package images, and ~/.bun/install/cache/... all resolve to npm/bun. upgrade() interprets those methods as "run npm install -g / bun install -g", and for patch releases this happens automatically at startup (src/cli/upgrade.ts:163, autoupdate defaults on) — silently creating a global install the user never had. The deleted probe loop returned unknown for these users (notify-only), so this is a behavior regression. Consider excluding known cache layouts (e.g. a _npx segment) or confirming the match sits under a real global root before returning a package-manager method.

WARNING: Preflight-blocked upgrades emit no telemetry event and no log entry
The preflight branch returns before the failure-handling block, so a permission-blocked upgrade produces neither the upgrade_attempted telemetry event nor the new Effect.logWarning("upgrade failed", ...). Before this PR the root-owned-npm-prefix case actually ran npm install -g, failed with EACCES, and was recorded as an upgrade_attempted error — the PR's flagship scenario now disappears from dashboards entirely, undercutting the goal of making failures distinguishable (this class reads as "no attempt" rather than "permission failure"). Consider tracking status: "error" with the permission classification (and logging the blocked directory) before returning the error here.

Consensus Code Review — Claude + GPT 5.4 Codex
Quorum not met — OpenRouter is out of credits. The configured review panel is Claude + 7 external models (quorum = 6). Only 2 of 8 reviewers produced output this round: Claude and GPT 5.4 Codex. Gemini 3.1 Pro (Antigravity) failed on a sandbox permission gate. The other five (Kimi K2.5, MiniMax M2.7, GLM-5.1, Qwen 3.6, MiMo V2 Pro) all failed because the shared
OPENROUTER_API_KEYis out of weekly credit — confirmed via a non-concurrent retry that still returned an explicit "requires more credits" error, not just in-flight-request contention. The two findings posted here as CRITICAL/MAJOR inline comments were independently corroborated (the critical one via direct source-level tracing ofpostinstall.mjs/bin/altimate/bin/altimate-code/publish.ts, not just diff inspection), so confidence remains high despite the reduced panel.
Verdict: REQUEST CHANGES — 1 CRITICAL, 2 MAJOR posted as inline comments below. One additional MINOR issue and full context follow.
Minor Issue (not anchorable as cleanly as the others, included here)
Global.Path.log diagnostic message points at a directory, not the actual log file — packages/opencode/src/installation/index.ts:601
`Details were written to ${Global.Path.log}.`,Global.Path.log is a directory (packages/core/src/global.ts:29 — log: path.join(data, "log")), not a file. The actual sink is path.join(Global.Path.log, "opencode.log") (packages/core/src/observability/logging.ts:49, fileLogger()), and the directory can contain other subdirectories too (e.g. direct/). Since the point of this PR is "make upgrade failures diagnosable," the pointer should be exact:
`Details were written to ${path.join(Global.Path.log, "opencode.log")}.`path and Global are already imported in this file.
Positive Observations
- Replacing a subprocess probe loop (up to seven package-manager spawns on the startup update-check path) with a pure, synchronous
resolveInstall(execPath, env)is a real startup latency and determinism win, and makes the logic unit-testable without real installs. - The regression test for the bug that originally motivated this PR (
.local/binmisclassification) is present and clearly named. - User-facing error messages and the telemetry payload consistently use stable classification codes (
classifyFailure()) rather than raw subprocess text. preflight()'s "skip if the directory doesn't exist yet" check correctly avoids false-positiving on package managers that create their prefix directory on first install.- Comments throughout (Cellar-not-prefix rationale, pnpm's dual-layout handling, the
npm bin -gremoval note) explain real, non-obvious constraints rather than restating the code.
Missing Tests
- Unscoped
npm install -g altimate-codelayout, including the cached-hardlink shapepostinstall.mjsactually produces (see the CRITICAL inline comment) — the most important gap. - A prefix/manager mismatch case (binary installed under one Node version, a different manager now first on
PATH). - A logger-sink test proving package-manager stderr/stdout does not reach OTLP export or
OPENCODE_PRINT_LOGSoutput. - Direct unit tests for
preflight()/globalDirs()/remediation()(currently only exercised indirectly throughInstallation.use.upgradeintegration tests for the npm/curl permission-denied cases).

CRITICAL — the primary, documented npm install path (npm install -g altimate-code) is misdetected as unknown, disabling auto-upgrade for most real users
PKG_SEGMENT_RE only matches paths containing node_modules/@altimateai/altimate-code (scoped). But every install instruction in this repo (README.md:30, docs/docs/getting-started.md:27, docs/docs/getting-started/quickstart.md:13, plus the CI examples) tells users to run:
npm install -g altimate-code # unscoped — no @altimateai/ prefixThis is a real, separately-published npm package — confirmed in packages/opencode/script/publish.ts:187-221, which explicitly publishes a second, unscoped altimate-code wrapper alongside the scoped one ("Publish unscoped altimate-code wrapper package so users can npm i -g altimate-code"), with identical bin/postinstall wiring.
The chain that breaks detection:
- On every non-Windows install,
postinstall.mjshard-links (or copies) the resolved platform binary to<wrapper-root>/bin/.altimate-code— inside the wrapper package's own directory, not the nested@altimateai/altimate-code-<platform>package. - Both
bin/altimateandbin/altimate-codecheck for that cached file first, before ever walking to the nested platform package:const cached = path.join(scriptDir, ".altimate-code") if (fs.existsSync(cached)) { run(cached) // <-- this is what actually runs on essentially every invocation }
- So in the running process,
process.execPath(and its realpath, since a hard link has no symlink to resolve away) is<prefix>/lib/node_modules/altimate-code/bin/.altimate-codefor the unscoped wrapper — no@altimateaisegment anywhere in the path. PKG_SEGMENT_RErequires that segment. It doesn't match, and none of the brew/scoop/choco/standalone regexes match either.resolveInstall()returns{ method: "unknown" }.
Effect: Installation.method() returns "unknown" for the majority of real installs, update-available checks silently stop offering upgrades, and altimate upgrade hits default: return yield* new UpgradeFailedError({ stderr: "Unknown installation method: unknown" }) — the exact class of opaque failure this PR is meant to fix.
test/installation/resolve-install.test.ts is comprehensive for the scoped-wrapper/nested-platform-package shape but has no fixture for the unscoped wrapper or for the cached-hardlink shape postinstall.mjs actually produces (which is what real invocations hit after the very first run).
Suggestion: Add fixtures for the unscoped wrapper and the cached-hardlink shape, and make the regex (or a second one) recognize node_modules/altimate-code/ in addition to node_modules/@altimateai/altimate-code. Since the cached path loses the platform suffix entirely, consider having postinstall.mjs write a small marker file (e.g. .install-manager) recording which manager ran the install, and have resolveInstall() prefer that when present.

Confirmed and fixed in 6ee55b6 — this was correct and I had missed it.
Verified the chain end to end: publish.ts does ship the unscoped altimate-code wrapper, README.md:30 and docs/docs/getting-started.md:27 both document it, and postinstall.mjs hard-links the platform binary to <wrapper>/bin/.altimate-code which both shims execute ahead of the nested platform package. Because a hardlink has no symlink for realpath to follow, execPath keeps the wrapper path and loses the platform suffix — so from the first run onward the scoped-only regex could not match.
PKG_SEGMENT_RE now treats the @altimateai/ prefix as optional, and test/installation/resolve-install.test.ts gained fixtures for the shapes that actually run: unscoped and scoped cached hardlinks, the unscoped nested platform package, and an unscoped wrapper under a pnpm global root.
I did not take the .install-manager marker suggestion. A marker is written by whichever installer ran, but cli/welcome.ts:60 deletes .install-source on first read by design so a stale value can never be attributed to a later install — a durable receipt would mean changing that lifecycle. The path shapes are now enumerated instead.

MAJOR — preflight/upgrade target whichever package manager is currently on PATH, not the one that produced the running binary
resolveInstall() only returns which manager produced the binary, never where (except for curl, via root). Both the writability preflight (globalDirs(), index.ts:290-320) and this upgrade() call shell out to whatever npm/pnpm/bun/yarn is currently first on PATH — not necessarily the one that installed the running binary. If the user has since switched Node versions (nvm/asdf), changed npm config set prefix, or changed PNPM_HOME/BUN_INSTALL, preflight() can check the wrong directory's writability and upgrade() can silently write to a different location than the one that actually holds the running binary — reporting success while the running executable is unchanged. text([process.execPath, "--version"]) further down (index.ts:640) discards both output and exit status, so there's no verification that the upgrade actually took effect.
This is a real gap in what "resolve the install from the running binary" promises, though it's a narrower, more expert-user-triggered scenario (multiple Node version managers, switched prefixes) than the unscoped-npm CRITICAL issue above.
Suggestion: Have resolveInstall() also report the resolved package/prefix and pass that root explicitly to preflight and to the install command (e.g. npm install -g --prefix <resolved-prefix> ...) rather than relying on ambient PATH state. After a successful upgrade, actually check process.execPath's reported version against target rather than discarding the verification call's result.

Partly addressed in 1ef5916 + 6ee55b6.
Done — no longer silently wrong. Installation.method() now confirms ownership before returning an actionable identity: it asks the manager for its global package root and checks the running binary is inside it. If a different npm is first on PATH, its npm root -g will not contain our executable, so we refuse with not-global rather than upgrading someone else`s install. That also covers the switched-prefix / nvm / asdf cases you describe — they resolve to a refusal rather than a wrong write.
Done — the verification call no longer discards its result. text([process.execPath, "--version"]) is now compared against the target, and a mismatch logs the running version, the execPath and a hint that the manager wrote elsewhere. It does not fail the operation: the package manager genuinely succeeded, and branch/dev builds legitimately report a different version string, so failing would produce false negatives.
Not done — the explicit --prefix. Pinning the resolved prefix into the install command changes install semantics (npm treats -g --prefix differently from a configured prefix, and pnpm/bun/yarn each spell it differently), so I would rather that be its own change than ride along here. The ownership check makes the current behaviour safe-by-refusal in the meantime rather than silently wrong. Happy to do it in a follow-up if you would prefer it in this PR.

MAJOR — failed-upgrade diagnostics log raw subprocess output through the general logger, which can fan out to OTLP/stderr
This branch logs raw stdout/stderr via Effect.logWarning. The inline comment claims this "stays local," but Effect.logWarning goes through the app's normal logger fan-out (packages/core/src/observability.ts:12), which includes an OTLP exporter (packages/core/src/observability/otlp.ts:47-49) whenever OTEL_EXPORTER_OTLP_ENDPOINT is set, and to stderr whenever OPENCODE_PRINT_LOGS=1. Package-manager stderr/stdout can contain credential-bearing registry URLs or other sensitive environment values.
Caveat (verified by Claude): this is not a new exposure this PR introduces — the success path a few lines below (Effect.logInfo("upgraded", { stdout, stderr, ... }), unchanged by this diff) already does exactly this, so the comment's "consistency, not new exposure" claim is accurate as far as it goes. But "the existing pattern is already like this" isn't the same as "the pattern is safe" — both paths remain conditionally exposed to OTLP/stderr export. OTLP export is opt-in (OTEL_EXPORTER_OTLP_ENDPOINT must be set), so this isn't exploitable in a default CLI run — weigh severity with that in mind.
Suggestion: Don't route raw subprocess output through the general Effect logger/OTLP fan-out. If raw diagnostics are valuable for support, write them to a dedicated local-only file (with restrictive permissions) after basic redaction, bypassing the OTLP/console sinks — for both this call and the pre-existing success-path one.
(Flagged by GPT 5.4 Codex; caveats added by Claude.)

Fixed in 1ef5916 + 6ee55b6 — and you were right to push past the "consistency, not new exposure" framing in my comment. That comment was mine and the reasoning behind it was wrong: I had told the user the log stays on the machine, which is false given the OTLP and stderr sinks you cite.
Two changes:
redactSecrets()masksBearertokens,authToken/api_key/password/secret/tokenassignments, credentialed URLs (https://user:pass@…) and long hex blobs before anything is logged.- It is applied to both paths. The previous commit only redacted the failure branch and left
Effect.logInfo("upgraded", { stdout, stderr })untouched — exactly the pre-existing call you pointed at. "The existing pattern already does this" is not a reason for either path to keep doing it.
Also: the user-facing message no longer promises a log artifact when an ERROR minimum log level would have discarded the WARN record.
I did not move raw output to a dedicated local-only file. Redacting at the source means every sink gets the same safe payload, whereas a second file would keep unredacted secrets on disk and add a path the user has to be told about. If you would rather have the raw output preserved for support, a restricted-permission file behind an opt-in flag would be the way — happy to add it, but it seemed worse than redacting given we found a real bearer token in this repo`s own test output last week.
) Self-review and CI turned up three problems with the previous commit. 1. The `.local/bin` claim was wrong, and removing the branch was a regression. The commit message and PR said `.local/bin` misclassified npm installs made with `npm config set prefix ~/.local`. It does not. With that prefix, packages land in `~/.local/lib/node_modules/...` and only the shim sits in `~/.local/bin`; since execPath is the spawned platform binary, it never contains `.local/bin` for a package-manager install, so the branch could not misfire that way. Removing it deleted correct back-compat from #820 (distro-resolved standalone installs), which test/sanity/Dockerfile also relies on, and broke four tests that said so explicitly. Restored — but AFTER the node_modules match, which is what makes it safe and is the real improvement over the original ordering. Both layouts now resolve correctly, with a test asserting exactly that. 2. Running prettier over the whole file reformatted code this change never touched (`upgradeCurl`, `upgradePowershell`, `defaultLayer`), because the committed file predates the repo's printWidth of 120. That broke two source-shape tests and tripped Marker Guard, which reads reformatted upstream lines as unmarked custom code. Formatting is not CI-enforced here, so it bought nothing. Rebuilt the file from the pristine version with only the intended edits re-applied. 3. `import { Global }` pulled in a module-load side effect: core/global.ts runs a top-level `await Promise.all([...mkdir...])`, creating seven directories merely by loading the module, and dragged that into every unit test importing resolveInstall(). Replaced with a lazy import matching the existing getTelemetry() pattern. Also converted the #820 detection tests from source-text assertions to behavioural ones now that resolveInstall() is pure, and documented that `access(W_OK)` reflects the read-only attribute rather than the ACL on Windows, so the preflight degrades to a no-op there instead of falsely blocking.

…locked-upgrade telemetry (#1305) Automated review of #1306 raised six findings. Each was verified against the code before acting; five were valid and are fixed here, one is declined with a reason. - **npx caches, download caches and project-local installs were attributed to a package manager.** `PKG_SEGMENT_RE` matches any `node_modules/@altimateai/altimate-code*` segment, not only global roots, so `npx`, a devDependency install, or a bun/npm cache resolved to `npm`/`bun`. `upgrade()` reads that as "run `install -g`", and for patch releases it runs automatically at startup — creating a global install the user never had. The deleted probe loop returned "unknown" for these, so this was a regression. Cache layouts are now excluded during detection, and `preflight()` additionally confirms the running binary actually lives under the manager's global root, failing open when that root cannot be determined. - **yarn classic on Windows was misclassified as npm.** Its global directory is `%LOCALAPPDATA%\Yarn\config\global`, which neither the `.yarn` nor the `yarn/global` spelling matched — so an upgrade would have run `npm install -g` over a yarn install, producing exactly the orphaned second binary this change exists to prevent. - **Preflight-blocked upgrades emitted no telemetry and no log entry**, so the flagship permission case read as "no attempt" on dashboards — strictly worse than the previous behaviour, which at least ran the command and recorded an error. Blocked attempts are now logged and tracked with their classification. - **The curl preflight checked the wrong directory.** It used the running binary's own directory, but the install script always writes to `$HOME/.altimate/bin`, so a legacy `~/.opencode/bin` install could pass preflight while a different directory was upgraded. - **The Chocolatey elevation message contradicted the classified cause** — it was returned unconditionally, so a network failure was reported as an elevation problem alongside a conflicting "Likely cause" hint. It is now used only for permission failures. - **The npm remediation told Windows users to run `sudo`**, which does not exist there; those users are now pointed at an elevated shell. - The error message now names `opencode.log` rather than the log directory, which also holds trace jsonl and heap dumps. Declined: switching `fs.accessSync` to `FileSystem.FileSystem`. It is the documented preference, but threading that service through requires widening the layer's dependency type and every downstream composition (`defaultLayer`, `node`) — well outside the scope of this fix, and raw `fs` already has precedent in sibling modules (cli/welcome.ts).

Exercise the package-layout cache exclusion.
resolveInstall() checks PKG_SEGMENT_RE before EPHEMERAL_SEGMENT_RE. This fixture has /install/cache/ but no node_modules/@altimateai/... segment, so it returns unknown without evaluating the exclusion. Bun’s documented cache layout stores packages directly under ~/.bun/install/cache, so this is not a realistic fixture for the package-manager branch.
Use a supported cache layout that matches both expressions, or document that Bun cache paths bypass the package-manager branch.

…rect package identities (#1305) Three-model consensus review plus cubic/CodeRabbit found nine issues in the previous round, five of them introduced by this branch. Each was verified against the code first. **Bun global upgrades were refused outright.** `bun pm bin -g` reports the SHIM directory (~/.bun/bin) while packages live in a sibling tree (~/.bun/install/global/node_modules). The ownership check treated the shim dir as the package root, so the real executable was never "inside" it. `globalLayout()` now returns `packageRoot` and `writable` separately — ownership is decided against the package tree, permissions against what the upgrade writes. **Ownership is now established before any consumer receives an actionable identity.** A path match is a hypothesis: a project-local node_modules is shaped exactly like a global one. `Installation.method()` confirms it with the manager and downgrades to `unknown` when the running binary is not in that manager's global tree. This matters because `cli/cmd/uninstall.ts` acts on the answer destructively and never runs the upgrade preflight. It also stops us mutating the wrong tree when a different `npm` is first on PATH — its `npm root -g` will not contain our executable, so we refuse rather than upgrade someone else's install. **Containment was unsound in both directions.** The lowercased `startsWith` matched `/prefix/lib/node_modules-other` against `/prefix/lib/node_modules`, resolved symlinks on only one side, and mis-compared on case-sensitive filesystems. Replaced with a separator-aware `path.relative` check. Its own test then caught a further bug: resolving only paths that exist compares /var against /private/var, so `realpathOr` now resolves the deepest existing ancestor and re-appends the remainder. **Diagnostics are redacted before they reach any sink.** The previous round logged package-manager stdout/stderr verbatim, justified by the log file staying local. That was wrong: `Logging.loggers()` adds a stderr logger under OPENCODE_PRINT_LOGS=1, and `Otlp.loggers()` ships records to a remote collector when OTEL_EXPORTER_OTLP_ENDPOINT is set — neither redacts, and npm error output routinely carries registry `_authToken` values. The message also no longer promises a log artifact that an ERROR log level would discard. **scoop/choco no longer resolve to an actionable method.** `latest()`/`upgrade()` still query and install the upstream `opencode` package, so an Altimate install resolving to those methods would pull in a different package. The old probe loop self-limited by requiring `scoop list opencode` to match; path matching has no such guard. Notify-only until those commands carry Altimate identities. **`uninstall` targeted upstream packages.** It ran `npm uninstall -g opencode-ai` and `brew uninstall opencode`, able to remove an unrelated upstream install while leaving Altimate in place. Pre-existing, but widened by this branch. **`yarn` is rejected where it was unhandled.** `Installation.upgrade()` has no `yarn` case; `cli/upgrade.ts` already routed it to notify, but `cli/cmd/upgrade.ts` and the HTTP upgrade route guarded only `unknown` and would have surfaced an opaque failure. Also: narrowed the pnpm/yarn patterns to real layouts instead of any `pnpm`/`yarn` path segment; excluded `dlx` caches alongside npx; renamed `ResolvedInstall.root` to `binDir` with an accurate description of what it holds. **Tests.** A previous guard asserted `INSTALLATION_SRC.toContain(".local")` against the whole file, which cannot detect the regression it claims to prevent — `.local` appears in three nearby comments, so deleting the regex alternation left it green. It now asserts against the regex line, verified by simulating the removal and watching it fail. Added ownership/containment coverage for the bun layout, prefix-sibling rejection, symlinked parents, and non-existent paths. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…ctions when unresolved (#1305) Three-model review (round 3) returned blocker-grade findings that all traced to the same root cause: identity was being inferred from the path string. A path cannot distinguish a top-level global install from a transitive dependency, and it cannot say which of our two published wrappers owns a platform package. Ownership is now a filesystem fact obtained from the package manager. `ownerOf(root, execPath)` asks which of `@altimateai/altimate-code` / `altimate-code` actually contains the running binary, and covers both real shapes: (a) the binary inside the wrapper — postinstall hard-links it to `<wrapper>/bin/.altimate-code` and the shims run that first; (b) the binary as one of our platform packages stored BESIDE the wrapper — pnpm's isolated store, hoisting, every Windows install (postinstall exits early there), and any install run with `--ignore-scripts`. (b) is bounded to that manager's own tree so a project-local binary cannot borrow a global wrapper's identity, and it refuses when BOTH wrappers are installed rather than guessing. `Installation.method()` returns a package-manager identity only when ownership is confirmed; otherwise `unknown`. That made `unknown` much more common, which exposed the consumer that had never been re-examined: **`uninstall` now refuses before removing anything when ownership is unresolved.** It was deleting data, config, cache and state unconditionally while skipping both the binary and the package removal — so an unverifiable install lost everything the user cared about and stayed installed, silently. It now stops and prints per-manager removal instructions. **The CLI upgrade dead end is gone.** "Install anyways?" passed `unknown` straight to `Installation.upgrade()`, which refuses it, so both answers ended in `UpgradeFailedError`. Replaced with actionable instructions. `UNSUPPORTED_UPGRADE_METHODS` is shared so the CLI and both HTTP routes reject the same set — the v2 handler had drifted to `unknown` only. `upgrade()` refuses yarn/scoop/choco at the choke point and the scoop/choco branches are deleted; they installed upstream's `opencode` package, not ours. Diagnostics are redacted before reaching any sink — the logger fans out to stderr under OPENCODE_PRINT_LOGS and to an OTLP collector when one is configured, so "it stays local" was never true. Masks now cover `Basic` blobs, quoted JSON keys and bare URL userinfo, and the post-upgrade `running:` field is redacted like every other subprocess-derived value. KNOWN OUTSTANDING — deliberately not fixed here, tracked for a follow-up: * `owningPackageOrScoped()` still falls back to the scoped name when a second manager query disagrees with the one `method()` already made. An unscoped install could then be upgraded under the scoped name, installing a duplicate. The fix is to resolve one identity and thread it through rather than re-deriving it per call site. * `resolveInstall()` picks a single candidate manager from path shape and only that one is queried, so a custom bun/pnpm directory without the expected segment resolves to npm, finds no owner, and degrades to `unknown`. Path shape should order which managers to ask, not decide the answer. * The standalone upgrade path still writes `$HOME/.altimate/bin` regardless of where the running binary lives. * Coverage is unit-level; there is no test across detection → upgrade → uninstall.

Consensus Code Review — Round 2 — Claude + GPT 5.4 Codex + GLM-5.1 + Qwen 3.6 + MiniMax M2.7
Quorum not met. Panel is Claude + 7 external models (quorum = 6). 5 of 8 produced output this round. Gemini 3.1 Pro (Antigravity) got stuck in a retry loop and was stopped after several minutes with no output; Kimi K2.5 and MiMo V2 Pro were both still mid-exploration after 20+ minutes with no forward progress and were stopped. This is a tooling/latency shortfall, not a credits issue — the OpenRouter key had a fresh weekly allowance this round. Despite the shortfall, the two most significant findings posted as inline comments (silent fallback to the wrong package; false-success telemetry) were found by GPT 5.4 Codex and independently confirmed by Claude via direct source-line tracing, so confidence in them is high.
Round-1 Fix Verification — all 4 confirmed FIXED
Unanimous across every reviewer that completed, and independently confirmed by Claude reading the current source directly (not just the commit messages):
| # | Round-1 issue | Status | Evidence |
|---|---|---|---|
| 1 | CRITICAL — unscoped npm install -g altimate-code misdetected as unknown |
FIXED | PKG_SEGMENT_RE (index.ts:83-84) now makes the @altimateai/ scope optional. resolve-install.test.ts covers both the scoped and unscoped cached-hardlink shapes. |
| 2 | MAJOR — preflight/upgrade targeted whatever manager was on PATH |
FIXED (see the inline comments below for a related gap) | Installation.method() now calls owningPackage() → ownerOf() to confirm the running binary is actually inside the candidate manager's global tree before returning an actionable identity; otherwise degrades to "unknown". |
| 3 | MAJOR — raw subprocess stdout/stderr logged, fans out to OTLP/stderr | FIXED | New redactSecrets() (index.ts:286-314) masks credential-shaped substrings; applied to both the failure path and the success path (previously unredacted). ownership.test.ts has 9+ redaction test cases. |
| 4 | MINOR — "Details were written to X" pointed at a directory | FIXED | New getLogFile() (index.ts:23-31) returns path.join(Global.Path.log, "opencode.log"), the actual file. |
Verdict: REQUEST CHANGES
3 MAJOR issues posted as inline comments on this review (silent fallback to the wrong package during upgrade/uninstall; false-success telemetry on a failed upgrade; subprocess spawns reintroduced into the startup path). The core round-1 bugs are genuinely fixed, and the new ownership-verification design (ownerOf(), isInside(), bunGlobalRoot()) is a real architectural improvement backed by a strong test suite — but the redesign introduces two new correctness bugs of its own, both in destructive/mutating code paths.
Minor Issues (not anchorable as cleanly, or below MAJOR threshold)
4. Uninstall's recovery instructions promise an impossible "re-run" — packages/opencode/src/cli/cmd/uninstall.ts:76
"Remove it with the tool you installed it with, then re-run to clean up data"
Once the user uninstalls the package via their manager, the altimate binary is gone — there is nothing to "re-run" altimate uninstall with. Provide a manual data/config cleanup path instead of promising a rerun that can't happen.
5. Generic <manager> uninstall -g <pkg> syntax is wrong for Bun and Yarn — packages/opencode/src/cli/cmd/uninstall.ts:77
" npm/pnpm/bun/yarn: <manager> uninstall -g @altimateai/altimate-code (or altimate-code)"
Bun's global-removal command is bun remove -g <pkg>, and Yarn's is yarn global remove <pkg> — neither is <manager> uninstall -g <pkg>. Print manager-specific lines.
6. Windows recovery messages show POSIX-only commands — packages/opencode/src/cli/cmd/uninstall.ts:79, packages/opencode/src/cli/cmd/upgrade.ts:63
Both files' "how to recover manually" messages hardcode rm the binary from ~/.altimate/bin and curl -fsSL ... | bash regardless of platform, even though the code elsewhere (upgradePowershell) already knows native Windows has no bash and uses %USERPROFILE%\.altimate\bin with a PowerShell installer instead.
7. --method CLI choices still list choco/scoop, which always fail — packages/opencode/src/cli/cmd/upgrade.ts:26 (pre-existing line, not part of this diff's hunks)
choices: ["curl", "npm", "pnpm", "bun", "brew", "choco", "scoop"],UNSUPPORTED_UPGRADE_METHODS (index.ts:341) = ["unknown", "yarn", "scoop", "choco"] — so --method choco/--method scoop are presented as valid CLI choices by yargs, but Installation.upgrade() always refuses them. Drop them from choices, or otherwise reconcile the two lists.
8. bunGlobalRoot() doesn't handle a custom Bun install.globalDir/globalBinDir — packages/opencode/src/installation/index.ts:220-222
Correct for Bun's default layout (the bot claim "every normal Bun install is rejected" is false — the default case works and is tested), but Bun allows install.globalDir/install.globalBinDir to be configured independently, and a non-default config would downgrade a valid install to "unknown". Narrow edge case, not a regression from round 1.
9. Ambiguous "(or altimate-code)" phrasing in recovery messages — packages/opencode/src/cli/cmd/upgrade.ts:61, packages/opencode/src/cli/cmd/uninstall.ts:77
(or altimate-code) appended after a full command line reads ambiguously — could be read as "or just run altimate-code" (which only launches the CLI) rather than "or install the unscoped package name instead." Rephrase as two explicit alternative commands.
Nits
10. Stale comment contradicts the redaction fix two paragraphs above it — packages/opencode/src/installation/index.ts:913-915
The old "the log file is local... consistency, not new exposure" reasoning is exactly what the author's own new redactSecrets() docblock (index.ts:279-283) calls false. Never updated when the redaction fix landed — now misleadingly implies the values below are raw when they're actually passed through redactSecrets().
11. ownership.test.ts leaks temp directories every run — packages/opencode/test/installation/ownership.test.ts:34,81
Neither describe block's fs.mkdtempSync() is cleaned up (no afterAll). Every test run leaves an ownership-* and an owner-* directory behind in the OS temp dir.
12. redactSecrets() has a narrow gap for short opaque tokens — packages/opencode/src/installation/index.ts:311-312
The catch-all patterns require 32+ hex chars or 40+ base64-ish chars; a short, unlabeled, non-keyed secret could slip through. Low real-world risk — most registry tokens are longer — but worth a test case.
Bot-Raised Claims Checked and Debunked
Several automated reviewers (kilo-code-bot, CodeRabbit, cubic-dev-ai) flagged issues against intermediate commits in this round that are not present in the final head (40779c55):
- Yarn Classic Windows global layout misclassified — false.
YARN_SEGMENT_REcorrectly matchesYarn\config\global; tested. - Every Bun global install rejected by preflight — false for the default layout (see Minor #8 for the narrower real edge case).
- Scoop/Chocolatey misclassification — not a bug;
resolveInstall()deliberately always returns"unknown"for these, sincelatest()/upgrade()reference the upstreamopencodepackage name for them (a separate, pre-existing issue this PR correctly chose not to touch). - "Do not continue with an unsupported Yarn method" (unhandled crash) — false;
yarnis inUNSUPPORTED_UPGRADE_METHODSand refused before reachingInstallation.upgrade(). - npm prefix containing a
pnpm/yarnpath segment misroutes upgrades — overstated; the ownership check normally degrades a contrived-prefix false match to"unknown"rather than performing the wrong upgrade, though no test currently pins this explicitly.
Positive Observations
ownerOf()/isInside()/bunGlobalRoot()are a genuine architectural improvement: separator-aware, symlink-resolved, and reject sibling-prefix and cross-tree false positives that earlier code got wrong.ownership.test.tsis strong: real filesystem fixtures, covers the pnpm sibling-store layout, the "both wrappers installed → ambiguous, refuse" case, and 9+ redaction shapes.- Redaction is now applied symmetrically to both the success and failure logging paths.
- Unverified ownership consistently degrades to
"unknown"/notify-only rather than guessing and acting — the one exception being the re-probe fallback flagged inline. - Scoop/Chocolatey no longer risk silently installing or removing the upstream
opencodepackage under Altimate's name. - The exact log filename and the
OPENCODE_LOG_LEVEL=ERROR"don't promise a file that wasn't written" case (getLogFile()) are thoughtful, non-obvious touches.
Missing Tests
- A test proving
method()'s subprocess count and whether automatic startup detection is spawn-free. - A test where the first ownership probe (
method()) succeeds and a second, independent probe fails — asserting upgrade/uninstall refuse rather than falling back to the scoped package. - Version-verification coverage for: matching version, mismatched version, empty stdout, non-zero exit, unlaunchable executable — each asserting telemetry/error status, not just the log line.
- A project-local
node_modulesinstall path throughresolveInstall()directly. - Bun with independently-configured
globalDir/globalBinDir. - An npm prefix containing a
pnpm/.yarn/yarn/config/globalsegment, pinning that it degrades to"unknown"rather than misrouting.

MAJOR — ownership is verified once in method(), then independently re-probed here and in uninstall.ts; a later failure silently falls back to the wrong package
const owningPackageOrScoped = Effect.fnUntraced(function* (m: Method) {
return (yield* owningPackage(m)) ?? "@altimateai/altimate-code"
})Installation.method() already verified ownership once (via owningPackage(), which spawns a manager query). But upgrade()'s command construction (this function, used at index.ts:846,851,856) and uninstall.ts:90 (Installation.packageName()) each independently re-run that same query later — a separate subprocess call that can transiently fail or race independent of the one method() already ran.
If a later probe fails where the first succeeded, this silently substitutes the scoped package name — even for a confirmed unscoped install:
- Upgrade: installs
@altimateai/altimate-code@targetas a brand-new duplicate, while the actual runningaltimate-codeinstall is left stale and un-upgraded — with the command still reporting success. - Uninstall (
uninstall.ts:90): if the second lookup fails aftermethod()'s already succeeded, uninstall proceeds to delete the user's config/data/cache and runs the uninstall command against a package that was never installed — silently removing nothing while wiping user state.
Suggestion: Resolve ownership once per operation into a single immutable value (method + verified package name + package root) and thread it through preflight/command-construction rather than re-querying. Fail closed — refuse the operation — rather than falling back to a guessed package name when the second lookup can't confirm what the first one did, especially for uninstall, which is destructive.
(Flagged by GPT 5.4 Codex; independently confirmed by Claude reading uninstall.ts:90 and the owningPackageOrScoped call sites in upgrade().)
There was a problem hiding this comment.
Fixed in 5d99234 — and you were right that the root was the re-probing, not the fallback line itself.
owningPackageOrScoped() is gone. identity() resolves the install once — method, verified owner, package root, writable dirs — and is memoised for the process. method(), packageName(), preflight() and the install-command construction all read that one value, so there is no longer a second query that can fail or race independently of the first. Nothing it reads can change while the binary is executing, so caching is safe.
Where a package name genuinely cannot be verified — an explicit --method override, or unconfirmed ownership — packageFor() still uses the scoped name, but logs package name not verified — assuming the scoped wrapper with the requested and resolved methods. The problem was that it was silent, not that a fallback exists; an override has to be able to proceed.
This also resolves the spawn-count comment: the re-probing is what produced ~7 subprocesses per upgrade. It is now one manager query (two spawns for npm), with verification still happening before any mutating action.
| // while the executable on disk was unchanged. We cannot fail the operation on this | ||
| // (the package manager did succeed, and a version string can legitimately differ for | ||
| // dev/branch builds), but it must not pass silently. | ||

MAJOR — a successful-looking upgrade can still leave the running binary unchanged, and telemetry has already recorded "success" before this check runs
const after = (yield* text([process.execPath, "--version"])).trim()
const normalize = (v: string) => v.trim().replace(/^v/, "")
if (after && normalize(after) !== normalize(target)) {
yield* Effect.logWarning("upgrade did not change the running binary", { ... })
}Telemetry is recorded as status: "success" a few lines above (index.ts:964-972) before this verification runs. If the versions mismatch, this only writes a log warning — it does not correct the already-recorded "success" telemetry, does not fail the upgrade() call, and the CLI (cli/cmd/upgrade.ts) still prints its normal "Upgrade complete" message to the user.
Worse: if text()'s subprocess call itself fails (execPath unlaunchable), text() swallows the error and returns "", and if (after && ...) treats an empty string as "nothing to check" — so an upgrade that leaves the binary literally unrunnable also reports success.
This is round 1's "an upgrade that wrote to a different location must not pass silently" concern, now partially addressed (there's a log line) but not actually resolved from the user's or the telemetry's point of view — it still passes silently everywhere that matters.
Suggestion: Move the verification before the success-telemetry write, and return an UpgradeFailedError (or a distinct "verification failed" status) rather than a log line when the version doesn't match or the binary can't be launched — reserve "we can't be sure, allow it" for a specifically-gated dev/branch-build case, not every upgrade.

Fixed in 5d99234.
Verification now runs before anything is reported. The success telemetry and the logInfo("upgraded") are both inside the verified branch, so a mismatch no longer has a status: "success" event already recorded ahead of it, and upgrade() returns an UpgradeFailedError so the CLI stops printing "Upgrade complete".
On the swallowed-spawn hole: the check uses run() rather than text(), so the exit status is visible. That let me split what was one boolean into three outcomes, which I think is the honest shape:
- non-zero exit — the binary cannot be started after the upgrade → failure, telemetry
error - exit 0, different version — the upgrade landed somewhere else → failure, telemetry
error - exit 0, empty output — ran but printed nothing → logged as
could not verify the upgraded binary, not claimed either way
I did not fold the third case into failure. The hole you identified was text() hiding a failed spawn, and that is now a non-zero exit and fails. An empty-but-successful probe is a different thing, and failing a good upgrade on it would trade one false report for another.
The error message names what the binary actually reports versus the target, and points at the log file.

MAJOR (severity disputed among reviewers) — Installation.method() is no longer spawn-free, and an actual upgrade can spawn up to ~7 subprocesses total
The PR's stated goal was removing subprocess spawns from Installation.method()'s hot path (down from up to 7). The new ownership check reintroduces 1-2 spawns into method() itself whenever the path-based candidate looks like a package manager (npm: 2, pnpm: 2, bun: 1, yarn: 2) — called from cli/upgrade.ts:108 on every startup update-check. For an actual altimate upgrade run, the same manager is queried again independently in preflight() and again in command construction (owningPackageOrScoped), plus one more for post-upgrade version verification: up to ~7 total subprocesses for one upgrade, comparable to the original bug this PR set out to fix.
Reviewers disagreed on how blocking this is:
- GLM-5.1: acceptable, necessary tradeoff — verifying ownership before a destructive/mutating action is the correct fix for round 1's PATH-drift issue, and the startup check itself is deferred via
setTimeoutso it doesn't block interactive startup. - Qwen 3.6 / MiniMax M2.7 / GPT 5.4 Codex: ownership confirmation shouldn't have been added to every
method()call — several callers (HTTP API version checks, the auto-update check) are read-only and don't need a definitive answer, only a best-effort one; it belongs only at the point of a mutating action.
Claude's read: the design is defensible — uninstall.ts genuinely needs a verified answer before deleting anything — but the repeated re-querying across method() → preflight() → owningPackageOrScoped() (see the sibling "silent fallback" finding on this PR) is not justified by that same argument, and is the more actionable half of this.
Suggestion: Have postinstall.mjs write a small marker file recording the manager and package name at install time, and have resolveInstall()/method() read that synchronously instead of spawning — falling back to the current subprocess-based ownerOf() check only for installs predating the marker or when it's missing/stale. This removes essentially all of the spawns for detection while preserving the safety property for destructive actions. (GPT 5.4 Codex and GLM-5.1 both suggested this independently.)
(Flagged by GPT 5.4 Codex, Qwen 3.6, MiniMax M2.7; GLM-5.1 disputes the severity.)
There was a problem hiding this comment.
Largely fixed in 5d99234, though by a different route than either side of the reviewer split proposed.
The ~7 subprocesses came from re-probing: method(), then preflight(), then command construction, then uninstall each re-derived ownership independently. identity() now resolves once and is memoised for the process, so an upgrade costs a single manager query (two spawns for npm) rather than one per call site.
That keeps GLM-5.1s position — verification before a mutating action is the right fix for the PATH-drift issue — without paying the cost the other three objected to. I did not make method()best-effort for read-only callers:cli/upgrade.ts` uses the same answer to decide whether to auto-upgrade, so a best-effort answer there would be acting on an unverified identity, which is the bug this PR exists to remove. With memoisation the read-only callers pay at most the first query and nothing after.
One thing I deliberately did not do: probing every manager when the path-hinted one finds no owner. It would resolve a custom layout whose directory carries no recognisable segment (your Minor #8), but it multiplies exactly the subprocess count this comment is about, to rescue a case that already degrades safely to notify-only. Recorded as a known limitation in the code and the commit rather than left implicit.
…#1305) Addresses the CHANGES_REQUESTED review on 40779c5. Its three MAJOR findings are not independent — they are two invariants this change had not finished — so they are fixed together rather than patched individually. **One identity, resolved once.** Ownership was verified in `method()`, then independently re-probed in `preflight()`, again when building the install command, and once more in `uninstall`. Each was a separate manager query that could fail or race independent of the one before it, and `owningPackageOrScoped()` turned a later failure into a silent substitution of the scoped package name. For a confirmed UNSCOPED install that meant upgrade installed a second, scoped copy while the real one stayed stale — reporting success — and uninstall deleted the user's data, then removed a package that was never installed. `identity()` now resolves once and is memoised for the process; nothing it reads can change while the binary is running. `packageFor()` uses the verified owner, and when a caller forces `--method`, or ownership is unconfirmed, it logs that it is assuming the scoped name rather than substituting quietly. That also answers the third finding: an upgrade previously spawned ~7 manager subprocesses because every call site re-derived the answer. It is now a single query (two spawns for npm), while keeping verification before any mutating action. **Report what actually happened.** Telemetry recorded `status: "success"` and the CLI printed "Upgrade complete" BEFORE checking whether the running binary had changed; a mismatch only wrote a log warning. The check also used `text()`, which swallows a failed spawn and returns "", and an empty string was read as "nothing to verify" — so an upgrade that left the binary unrunnable reported success. Verification now runs first, via `run()` so the exit status is visible, and distinguishes three outcomes: a non-zero exit (the binary cannot start) and a contradicting version both fail the upgrade and record an error; exit 0 with no output is reported as unverifiable rather than being claimed either way. Review minors, all fixed: * uninstall no longer tells the user to "re-run" a command whose binary they have just removed; it names the data/config/cache/state directories to delete by hand. * per-manager removal and upgrade syntax — `bun remove -g` and `yarn global remove` are not `<manager> uninstall -g`. * Windows recovery text no longer prints POSIX-only paths and `curl … | bash`; it uses `%USERPROFILE%\.altimate\bin` and the PowerShell installer. * `--method` no longer offers `choco`/`scoop`, which `Installation.upgrade()` always refuses. Help snapshot updated. * the ambiguous trailing "(or altimate-code)" is now an explicit sentence about the scoped vs unscoped package name. * `bunGlobalRoot()` falls back to BUN_INSTALL when a configured `install.globalBinDir` breaks the derivation, and returns "" when bun reports nothing. * stale comment claiming the failure log "stays local" — the claim `redactSecrets()`'s own docblock calls false — removed. * `ownership.test.ts` no longer leaks a temp directory per run; short-token redaction shapes pinned. Known limitation, deliberate: only the manager the path points at is queried. Probing every manager would resolve a custom layout whose directory carries no recognisable segment, but it multiplies the subprocess count this change exists to reduce, to rescue a case that already degrades safely to notify-only.

Consensus Code Review — Round 3 — Claude + Qwen 3.6 + MiniMax M2.7 + GLM-5.1
Quorum not met. Panel is Claude + 7 external models (quorum = 6). 4 of 8 produced usable output this round. Gemini 3.1 Pro (Antigravity) hit the same persistent sandbox command-permission gate seen in round 2. GPT 5.4 Codex wandered into unrelated exploration of an unrelated local worktree directory and was stopped after ~20 minutes with no findings. Kimi K2.5 and MiMo V2 Pro both produced very large tool-trace dumps (600KB+) without reaching a structured conclusion within a long wait and were stopped. Despite the shortfall, all 3 findings below reached unanimous agreement among the 3 external reviewers that did complete — independently of each other, before any cross-model convergence step — and Claude verified the exact mechanism of each directly against the current source. Confidence is high notwithstanding the quorum gap.
Round-2 Fix Verification — all 3 confirmed FIXED
| # | Round-2 issue | Status | Evidence |
|---|---|---|---|
| 1 | MAJOR — ownership re-probed independently at each call site; silent fallback to the wrong package on a later failure | FIXED | New identity() (index.ts:587-601) resolves method + verified owner + package root + writable dirs once, memoised for the process. method(), packageName(), preflight(), and packageFor() (replacing owningPackageOrScoped()) all read this single value. |
| 2 | MAJOR — upgrade success telemetry recorded before post-upgrade verification ran | FIXED | Verification now runs before success is reported, uses run() instead of text() (exit status visible), and a real mismatch returns UpgradeFailedError with status: "error" telemetry rather than a silent log line. |
| 3 | MAJOR (disputed) — up to ~7 subprocesses per upgrade from repeated re-querying | FIXED for the repeated-query part | The same identity() memoization collapses this to one manager query per process. The base tradeoff (some spawn cost to verify ownership before a mutating action) remains — that was always the accepted part of the disagreement. |
Verdict: REQUEST CHANGES
1 CRITICAL and 1 MAJOR issue posted as inline comments on this review (a Homebrew upgrade-verification false-negative, and a memoization race condition in the new identity() design). This is a well-executed round of fixes overall — the identity() redesign is exactly the right shape for what round 2 asked for — but it introduces one new, likely-high-frequency correctness bug that should block merge.
Minor Issue
3. cli/cmd/upgrade.ts's unsupported-method recovery message omits Yarn — packages/opencode/src/cli/cmd/upgrade.ts:67 (insert after the bun line)
The message shown when the detected/forced method can't be auto-upgraded lists npm, pnpm, bun, Homebrew, and the installer — but not yarn, even though yarn is a real value in UNSUPPORTED_UPGRADE_METHODS (index.ts:354) that routes here. uninstall.ts's equivalent message already includes a yarn line (yarn global remove altimate-code) — simple parity gap.
prompts.log.info(" yarn: yarn global add altimate-code@latest")(Flagged independently by Qwen 3.6, MiniMax M2.7, GLM-5.1, and cubic-dev-ai. Claude confirmed by comparing against uninstall.ts's equivalent message, which does include yarn.)
Positive Observations
identity()is precisely the fix round 2 asked for: single resolution, memoised for the process, eliminating the re-probing class of bug entirely (modulo the concurrency issue above, which is about the memoization primitive, not the design).- The post-upgrade verification's three-outcome design (
unrunnable/contradicted/ ran-but-no-output) is a real improvement over round 2's boolean check. redactSecrets()continues to cover new shapes found in review (Basic-auth blobs, quoted JSON keys, bare URL userinfo) — visible iteration, not a one-and-done fix.- Every remaining round-2 minor/nit issue was independently confirmed fixed by Claude reading the current source: the impossible "re-run" instruction, wrong bun/yarn uninstall syntax, Windows/POSIX recovery-message mismatch,
choco/scoopCLI choices, ambiguous "(or altimate-code)" phrasing, the stale contradictory comment, custom BunglobalDir/globalBinDirhandling, and theownership.test.tstemp-directory leak all now have code (and in most cases tests) addressing them.
Missing Tests
- A test that mocks the Homebrew Cellar-cleanup scenario:
process.execPathpointing at a path that no longer exists after a successfulbrew upgrade, asserting the upgrade is still reported as a success (once the Critical finding is fixed). - A concurrency test exercising
identity()(orInstallation.method()) called twice in parallel, asserting both calls converge on the same result rather than racing. - A test asserting the
yarnline is present incli/cmd/upgrade.ts's unsupported-method message.

CRITICAL — Homebrew upgrades are very likely to be misreported as failures
The post-upgrade verification re-executes process.execPath to confirm the upgrade landed:
const verify = yield* run([process.execPath, "--version"])For a Homebrew install, process.execPath (resolved via realExecPath(), which follows the Cellar symlink) points into a versioned Cellar directory, e.g. /opt/homebrew/Cellar/altimate-code/1.0.0/bin/altimate. Homebrew's default behavior since 4.0 is to clean up the just-upgraded formula's old version automatically after a successful brew upgrade (unless HOMEBREW_NO_INSTALL_CLEANUP=1 is set) — so after brew upgrade altimate-code succeeds, the specific path process.execPath refers to commonly no longer exists on disk.
When that happens, run([process.execPath, "--version"]) returns a non-zero exit (ENOENT), which is classified as unrunnable, and this function returns an UpgradeFailedError saying the binary "could not be started afterwards" and that "the upgrade was most likely written to a different location than the binary you are running" — for what was, in fact, a completely successful upgrade. This is the exact class of false diagnostic this whole PR (#1305) exists to eliminate, now reintroduced for a documented, common install method (Homebrew is one of the primary supported channels on macOS).
Suggestion: Don't re-verify against the pre-upgrade process.execPath for brew. Re-resolve the current binary location after the upgrade instead — e.g. via brew --prefix <formula> (the formula name is already available from getBrewFormula(), reused elsewhere in this same function) plus the package's bin/altimate, or simply skip the unrunnable/contradicted check for m === "brew" and trust brew upgrade's own exit code, since Homebrew already manages its own binary lifecycle:
if (m === "brew") {
const prefix = (yield* text(["brew", "--prefix", formula])).trim()
const verifyPath = prefix ? path.join(prefix, "bin", "altimate") : process.execPath
const verify = yield* run([verifyPath, "--version"])
// ...
} else {
const verify = yield* run([process.execPath, "--version"])
// ...
}(Flagged independently and with matching root-cause analysis by Qwen 3.6, MiniMax M2.7, and GLM-5.1 — all 3 completed external reviewers this round, plus originally surfaced by cubic-dev-ai. Claude independently confirmed the mechanism by reading getBrewFormula(), the brew case in upgrade(), and the verification block, and found no existing brew-specific handling.)

Fixed in c6e9c51. This one was a genuine own-goal: the verification added last round to stop false successes became a source of false failures, for a primary supported channel.
Traced the mechanism rather than taking the report on faith — realExecPath() follows the Cellar symlink, so process.execPath is the versioned path (…/Cellar/altimate-code/<version>/bin/altimate), and brew upgrade removes the old version on success by default since 4.0. The path we re-execute is exactly the one the upgrade just deleted.
I did not special-case brew. The guard is that the path still exists:
if (!fs.existsSync(process.execPath)) { /* log + success, with a note */ return }
const verify = yield* run([process.execPath, "--version"])Any installer that relocates rather than overwrites has the same shape, and if (m === "brew") would only wait to be rediscovered by whichever channel does it next. A path that has vanished after the manager reported success means the install moved — unverifiable, not failed — so it is recorded as a success with a note naming why it could not be verified, rather than claiming a verification that never happened.
I did not take the brew --prefix <formula> route: re-resolving the new location would let us verify brew specifically, but it re-derives an install location at execution time, which is the pattern rounds 2 and 3 were spent removing.
Test added for the precondition the fix turns on.

MAJOR — identity()'s memoization has a check-then-act race under concurrent access
let cached: ResolvedIdentity | undefined
const identity = Effect.fnUntraced(function* () {
if (cached) return cached
const candidate = resolveInstall().method
const layout = yield* globalLayout(candidate) // <-- yields (spawns a subprocess) here
// ...
cached = /* ... */
return cached
})This is a classic check-then-act race on an async computation: the function checks cached, then yields on a subprocess spawn before assigning cached. If two concurrent calls both enter before either finishes, both independently compute a result, and whichever finishes last silently overwrites cached — including a slower, degraded/failed probe overwriting an earlier, correct one. Since cached lives for the process lifetime, that downgrade (e.g., to { method: "unknown" }) then persists for every subsequent call until the process restarts.
This is reachable in practice: packages/opencode/src/server/routes/global.ts calls Installation.method()/Installation.upgrade() from HTTP handlers, and the server (Hono) handles requests concurrently — two near-simultaneous version-check or upgrade requests would race here.
Consequence is bounded, not destructive: a corrupted "unknown" result degrades to notify-only rather than triggering a wrong mutating action (per the design verified fixed in round 2) — so the blast radius is "auto-upgrade stops working until the process restarts," not data loss or a wrong package being touched.
Suggestion: Use Effect.cached (or an equivalent in-flight-dedup primitive) around the identity() computation rather than a plain variable with a check-then-act pattern — that's exactly the primitive Effect provides for "compute once, share the in-flight promise with concurrent callers, then memoize the result."
(Flagged independently by Qwen 3.6, MiniMax M2.7, GLM-5.1, and the automated reviewer cubic-dev-ai — all converging on the same root cause and the same Effect.cached-style fix. Claude independently confirmed the race by reading the function and tracing that Installation.method()/Installation.upgrade() are reachable from concurrent HTTP handlers in server/routes/global.ts.)

Fixed in c6e9c51, using Effect.cached as suggested.
const cachedIdentity = yield* Effect.cached(computeIdentity)
const identity = () => cachedIdentityThat is the primitive the repo already uses for this shape (core/src/image.ts:50, http-recorder/src/recorder.ts:32), and it dedupes the in-flight computation rather than only its result — which is the actual difference, since the racy version assigned only after the spawn had resolved.
Your reachability note was the part I had missed: I edited both HTTP routes in this same PR and still did not ask what happens when two of them land together. The let cached was written to fix re-probing and only ever considered against re-probing.
Agreed on blast radius — a corrupted unknown degrades to notify-only rather than a wrong mutating action, which is the round-2 design holding. Still worth fixing, because it pins that degraded answer for the life of the process.
Added the concurrency test you asked for: three concurrent Installation.method() calls, asserting they agree AND that the manager query ran at most once. The second assertion is what actually distinguishes the two implementations — agreement alone passes with the racy version whenever both probes happen to succeed.
…tion race-free (#1305) Round-3 review findings. Both are regressions introduced by round 2's own fixes, and both share a cause: the new mechanism was tested against the complaint that prompted it, not against itself. **Homebrew upgrades were reported as failures (CRITICAL).** Round 2 added a post-upgrade check that re-executes `process.execPath` to confirm the upgrade landed. For a Homebrew install that path resolves into a versioned Cellar directory, and `brew upgrade` cleans up the old version on success by default since 4.0 — so the path the check re-executes has commonly just been deleted. The spawn fails with ENOENT, which the check classified as "the binary could not be started afterwards", turning a completely successful upgrade into a confident false diagnostic: the exact failure class this change exists to remove. Guarded on the path still existing rather than on `m === "brew"`. Any installer that relocates instead of overwriting has the same shape, and a path that has vanished after the manager reported success means the install moved — which is unverifiable, not failed. It is logged and reported as a success with a note, since the manager's own exit status is the only evidence available at that point. **`identity()`'s memoization had a check-then-act race (MAJOR).** `if (cached) return cached` followed by a `yield` on a subprocess spawn before the assignment: two concurrent callers each compute a result and the slower overwrites the faster. The Hono routes serve requests in parallel and both reach `method()`, so a degraded probe landing second would pin `unknown` for the remaining life of the process. Replaced with `Effect.cached`, the primitive already used for this in `core/src/image.ts` and `http-recorder`, which dedupes the in-flight computation rather than only its result. Also: the unsupported-method recovery message in `cli/cmd/upgrade.ts` omitted yarn, which is in `UNSUPPORTED_UPGRADE_METHODS` and routes there — `uninstall.ts` already had its line. Tests, all three the review asked for: * the relocated-binary precondition the Homebrew fix turns on; * concurrent `method()` calls sharing a single manager query and agreeing, which is what distinguishes `Effect.cached` from the racy variable; * per-manager recovery guidance parity between upgrade and uninstall, covering every method that can route to those messages. One consequence worth recording: the verification now correctly catches the documented standalone limitation. Running from `~/.local/bin` while the install script writes `$HOME/.altimate/bin` leaves `execPath` present but reporting the old version, so the upgrade now fails loudly instead of silently reporting success. The limitation itself is still outstanding. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

On the pattern across rounds, since it is the more useful thing to record: both of this rounds findings were regressions from round 2s own fixes, and they share one cause — I tested each new mechanism against the complaint that prompted it and never against itself. For the post-upgrade check I asked "does this catch the false success?" but not "when is the verifier wrong?"; for the memoization I asked "does this stop re-probing?" but not "what happens concurrently?" — while having edited the concurrent HTTP routes in the same PR. Both were knowable before pushing. Note: this branch is 3 commits behind Still outstanding and documented in code, unchanged this round: only the path-hinted manager is queried; no explicit |

CRITICAL: A transitive platform package can borrow an unrelated global wrapper's identity
This fallback proves only that the executable is somewhere under the manager tree and that exactly one Altimate wrapper exists at the global root. For example, <root>/another-cli/node_modules/@altimateai/altimate-code-linux-x64/bin/altimate-code satisfies PLATFORM_PKG_RE and containment, so a separate top-level altimate-code makes this return altimate-code even though that wrapper did not launch the process. method() then authorizes the install as actionable, and uninstall can remove that unrelated wrapper and delete the user's data. Tie the platform package to the selected wrapper/store entry instead of inferring ownership from coexistence in the same global tree.

WARNING: Valid package-manager targets are rejected after a successful upgrade
The CLI passes its free-form target directly to npm/pnpm/bun, so values such as latest, beta, or ^1.2 are valid manager targets. After installation, --version returns the resolved concrete version, which can never equal those strings; this branch therefore emits error telemetry and throws after the upgrade already succeeded. Resolve tags/ranges to a concrete version before verification, or validate the reported version with tag/range-aware semantics.

Consensus Code Review — Round 4 — Claude + Qwen 3.6 + MiniMax M2.7
Quorum not met. Panel is Claude + 7 external models (quorum = 6). 3 of 8 produced usable output this round. Gemini 3.1 Pro (Antigravity) ran for ~10 minutes burning real CPU but never wrote any output — a new, unexplained failure mode distinct from the permission-gate hangs seen in rounds 2–3. GPT 5.4 Codex made slow, genuine progress (reading Effect's internal
Effect.cachedsource to verify a claim) but did not finish in the available window. GLM-5.1, Kimi K2.5, and MiMo V2 Pro were all still actively running (real, growing CPU time — not deadlocked) without reaching a structured conclusion and were stopped after an extended wait; Kimi in particular produced 800KB+ of tool-trace output with no synthesis. Despite the shortfall, this round's headline finding is a precise, 100%-reproducible bug independently confirmed by both external reviewers that completed, and Claude verified the exact trigger line-by-line — this is not a probabilistic or disputed finding.
Round-3 Fix Verification — both confirmed FIXED
| # | Round-3 issue | Status | Evidence |
|---|---|---|---|
| 1 | CRITICAL — Homebrew's Cellar auto-cleanup deletes the pre-upgrade binary path, so re-executing process.execPath for verification hits ENOENT and misreports success as failure |
FIXED | index.ts:1040: if (!fs.existsSync(process.execPath)) { ...log "the upgrade relocated it"...; return success } — general, not brew-specific, which correctly also covers other managers that relocate rather than overwrite. |
| 2 | MAJOR — identity()'s let cached memoization was a check-then-act race under concurrent access |
FIXED | Effect.cached(computeIdentity) dedupes the in-flight computation, not just the result — exactly what closes the race. A new concurrency test was added. |
Verdict: REQUEST CHANGES
1 CRITICAL and 2 MAJOR issues posted as inline comments. The Homebrew and race-condition fixes are both correct and well-reasoned. But verifying them surfaced a sharper, unrelated bug in the same verification codepath: it doesn't just misfire on Homebrew's cleanup timing — it's unconditionally wrong whenever a user passes a non-exact-version upgrade target, which is a very natural thing to try (altimate upgrade latest).
Minor Issue
Recovery guidance in upgrade.ts always suggests @latest, ignoring the target the user actually requested — When the detected/forced method can't auto-upgrade, the guidance always prints npm install -g altimate-code@latest etc., even if the user ran altimate upgrade 0.8.10. Interpolate the requested target (falling back to @latest only when none was given).
(Confirmed by Qwen 3.6 and MiniMax M2.7.)
Positive Observations
- Both round-3 fixes are exactly the right shape: the
fs.existsSyncguard for relocated binaries andEffect.cachedfor the race are correct, minimal, well-explained changes. - A new concurrency test was added alongside the
Effect.cachedchange, verifying concurrent callers share one resolution. redactSecrets(),classifyFailure(), and the ownership/resolve-install test suites continue to be genuinely thorough — this reviewer team has consistently found this PR's test coverage a strength across all four rounds.
Missing Tests
- A test asserting
altimate upgrade latest(and a dist-tag/range target generally) is verified successfully rather than reported as failed, once the Critical finding is fixed. - The exact
ownerOf()scenario from the inline finding: a single top-level wrapper present, plus an unrelated sibling package's transitive platform-package dependency, asserting the function returnsundefined. - A test for the transient-failure-then-recovery scenario described in the
Effect.cachedfinding, once/if a retry is added.

CRITICAL — altimate upgrade latest (or any non-exact-version target) always misreports a successful upgrade as failed
const target = args.target ? args.target.replace(/^v/, "") : await Installation.latest()When the user supplies an explicit target argument, it is used verbatim — Installation.latest() is only called when args.target is absent. So altimate upgrade latest sets target = "latest" and that literal string flows into Installation.upgrade(method, target), which passes it straight to the package manager (npm install -g altimate-code@latest, etc.). npm/pnpm/bun correctly resolve "latest" to a concrete version and install it successfully — but the post-upgrade verification (index.ts:1069) then compares the actual resolved version against the literal string "latest":
const contradicted = after !== "" && normalize(after) !== normalize(target)normalize("0.12.0") !== normalize("latest") is always true — there is no code path that ever makes these equal. The result: every altimate upgrade latest succeeds at the package-manager level and is then unconditionally reported as a failure, with a misleading "the package manager reported success but wrote somewhere other than the running executable" message. The same applies to any dist-tag (beta, next) or semver range (^0.12.0) passed as an explicit target.
This is not probabilistic or environment-dependent like the Homebrew Cellar-cleanup finding from last round — it is deterministic and 100% reproducible. It also breaks the "already up to date, skip" fast path a few lines above (Installation.VERSION === target), which likewise can never match a tag/range string. altimate upgrade latest mirrors a convention users already know from npm install -g pkg@latest, so this is a realistic, not contrived, way to trigger it.
Suggestion: Resolve target to a concrete version before it's used for anything comparison-sensitive:
const target = args.target
? args.target.replace(/^v/, "")
: await Installation.latest()
const resolvedTarget =
/^\d+\.\d+\.\d+/.test(target) ? target : await Installation.latest()(Or, more robustly, have the post-upgrade verification treat a non-semver target as "cannot verify against this value" rather than as a hard mismatch — falling back to the existing "ran but reported no comparable version" branch instead of the contradicted branch.)
(Independently found by MiniMax M2.7 with this precise line-level trace; Qwen 3.6 flagged the general shape — comparing raw target against resolved version — in less precise form. Claude confirmed the exact mechanism by re-reading this ternary's control flow.)
There was a problem hiding this comment.
Fixed in cc57ee1. This one was unambiguous and I should have caught it when I wrote the check — target is whatever the caller passed, and I never asked what values it can take before comparing a resolved version against it.
Verification now only contradicts when the target is an exact version:
const exactTarget = semver.valid(normalize(target)) !== null
const contradicted = exactTarget && after !== "" && normalize(after) !== normalize(target)A dist-tag or range is logged as "not verified against it" rather than failed — comparing a resolved version to an unresolved specifier is not a check, so the honest outcome is "unverifiable", the same category already used for a binary that runs but prints nothing.
I did not resolve the specifier up front instead (calling latest() when the target is not exact). It would restore a real check, but each manager resolves tags and ranges by its own rules, so we would be re-implementing their resolution to grade their work — and getting that subtly wrong reintroduces exactly this class of false failure.
Tests cover latest, beta and ^0.12.0 not failing, plus an exact target that genuinely does not match afterwards still failing, so the check has not simply been weakened into a no-op.

PLATFORM_PKG_REmatches (it's a valid@altimateai/altimate-code-<platform>path) — doesn't returnundefined.isInside(execPath, root)is true (some-other-cliis literally a subdirectory ofroot) — doesn't returnundefined.present.length === 1→ returns"altimate-code".
Nothing in this path verifies that the platform package under some-other-cli/node_modules/ is actually a dependency of altimate-code specifically, as opposed to a dependency of the unrelated some-other-cli package that happens to sit in the same global root. The docblock states intent — "(b) is bounded to the manager's own tree so a project-local binary cannot borrow a global wrapper's identity" — but "bounded to the manager's tree" (step 3) is weaker than "actually belongs to this wrapper," which is what's needed.
Practical severity note: the real-world trigger requires some other, genuinely unrelated global npm package to declare @altimateai/altimate-code-<platform> as its own dependency — implausible for truly unrelated software. If it does happen (e.g. a corrupted or unusual layout), uninstall() — which is destructive — could remove the wrong (unrelated, legitimate) install.
Note on reviewer disagreement: one external reviewer (MiniMax M2.7) assessed this as a false positive, claiming present.length === 1 "returns undefined when... the binary is not inside either of its directories." That check does not exist in the code above — I re-verified byte-for-byte against the raw source and there is no such additional negative check gating the final return statement. A second reviewer (Qwen 3.6) independently traced the same mechanism described here, though stopped short of a firm conclusion.
Suggestion: Require the platform package's containing node_modules to be a direct sibling of (or nested one level inside) the specific candidate wrapper's own store entry, not merely "somewhere under the global root." Add a test for this exact scenario (single wrapper present, plus an unrelated sibling's transitive platform-package dependency) — ownership.test.ts currently covers the fully-unrelated-root case and the both-wrappers-ambiguous case, but not this one.

Fixed in cc57ee1 — the trace is correct, step by step, and the contest over real-world likelihood does not change that the code cannot tell the two cases apart.
You identified the gap exactly: my docblock claimed "bounded to the manager's own tree", and step 3 only checks that. Being under the root is much weaker than belonging to our wrapper.
The check is now on placement rather than mere containment. Only two positions mean the platform package was installed for us — hoisted to the manager's own top level, or held in its virtual store — so the first path segment relative to the tree root must be @altimateai or a dot-prefixed store directory:
const first = path.relative(realpathOr(base), realpathOr(execPath)).split(path.sep)[0] ?? ""
const hoisted = first === "@altimateai"
const virtualStore = first.startsWith(".") && first !== "." && first !== ".."
if (!hoisted && !virtualStore) return undefined<root>/some-other-cli/node_modules/@altimateai/... yields some-other-cli and is rejected.
On the severity dispute: I treated it as worth fixing regardless of trigger likelihood. The consequence is not a cosmetic misreport — it is upgrading or removing OUR package because an unrelated package declared the platform build as a dependency, and the cost of the guard is one string comparison.
Added the test you asked for, plus its complement — a hoisted platform package IS ours — so the fix cannot be tightened into rejecting a legitimate layout without something failing.

MAJOR (disputed severity, mechanism confirmed) — Effect.cached permanently locks in a degraded resolution from a single transient failure
computeIdentity never fails in the Effect sense — globalLayout()'s underlying text() helper swallows a failed subprocess spawn and resolves to "" as a successful value, which flows through to a successful { method: "unknown", ... } ResolvedIdentity. Effect.cached memoizes whatever the wrapped effect first resolves to, success or degraded-success alike — it has no concept of "retry because this answer looks bad." So a single transient spawn/resource hiccup on the first call permanently caches "unknown" for the rest of the process's lifetime, disabling auto-upgrade and blocking uninstall until a restart, even though the underlying manager would have answered correctly moments later.
Consequence is bounded, not destructive: per the design's own philosophy, "unknown" degrades to notify-only rather than driving a wrong mutating action — so the blast radius is "auto-upgrade silently stops working until restart," not data loss.
Reviewer disagreement: one external reviewer (Qwen 3.6) confirmed this as a real design gap worth fixing (suggesting a bounded retry before the cache point). Another (MiniMax M2.7) called it "not applicable," reasoning that since there's no Effect-level Exit.Failure involved, the cache is "doing exactly what it should." Both descriptions of the mechanism agree; the disagreement is purely about whether permanently caching a transient-failure-driven "unknown" is a bug or an acceptable, intentional tradeoff. I'd lean toward fixing it, given the fix is cheap and the alternative (silent, unexplained loss of upgrade capability until restart, on a long-running server process) is a real support burden — but this is a legitimate judgment call, not a clear-cut defect the way the target-comparison bug is.
Suggestion: Wrap computeIdentity (or just globalLayout's subprocess calls) in a small bounded retry (e.g. Effect.retry({ times: 2, delay: Duration.millis(200) })) before it reaches Effect.cached, so a single transient hiccup doesn't get permanently enshrined.
There was a problem hiding this comment.
Fixed in cc57ee1. Both reviewers described the same mechanism, and I agree with Qwen that it is worth fixing — the MiniMax rebuttal ("no Exit.Failure, so the cache is behaving correctly") describes what Effect.cached does, not whether what it caches is a fact.
That is the actual distinction the fix encodes:
return { method: "unknown", packageRoot: "", writable: [], unprobed: layout.packageRoot === "" }"The manager answered and we are not in its tree" is a durable fact about this install and is cached. "The manager did not answer" is a fact about one probe and is not. Only the second is retried.
Reviewing that fix before pushing turned up a second problem with the obvious shape of it: a plain if (unprobed) recompute would re-spawn the manager on every call for anyone whose manager genuinely is not installed — on the startup update-check path — trading a stuck cache for unbounded spawning. So the retry is itself memoised:
const firstAttempt = yield* Effect.cached(computeIdentity)
const resolvedIdentity = yield* Effect.cached(
Effect.gen(function* () {
const first = yield* firstAttempt
if (!first.unprobed) return first
return yield* computeIdentity
}),
)Exactly one extra attempt, shared by all callers, no check-then-act window, and a second failure is accepted rather than re-probed forever.
Agreed the blast radius was bounded — unknown degrades to notify-only, which is the round-2 design holding.
…ckages (#1305) Round-4 review findings, plus two more found by applying the same adversarial pass to the fixes themselves before pushing rather than after. **`altimate upgrade latest` always reported a successful upgrade as failed (CRITICAL).** `cli/cmd/upgrade.ts` forwards `args.target` verbatim, so a dist-tag (`latest`, `beta`) or a range (`^0.12.0`) reaches `upgrade()` as a literal string. The manager resolves it correctly and installs a concrete version — which the post-upgrade check then compared against the unresolved literal. `normalize("0.12.0") !== normalize("latest")` is true for every input, so there was no path on which a non-exact target could pass. Comparing a resolved version against a specifier is not a check; it is a guaranteed mismatch. Verification now only contradicts when the target is an exact version (`semver.valid`), and logs that it could not verify otherwise. **`ownerOf()` could attribute another package's dependency to our wrapper (MAJOR).** Being somewhere under the manager's root is weaker than belonging to our package: `<root>/some-other-cli/node_modules/@altimateai/altimate-code-<platform>/...` satisfied the containment check and was claimed by whichever single wrapper happened to be installed. Only two placements actually mean the platform package was installed for us — hoisted to the manager's own top level, or held in its virtual store — so the first path segment relative to the tree root now has to be `@altimateai` or a dot-prefixed store directory. **A transient probe failure was cached for the life of the process (MAJOR).** `computeIdentity` never fails in the Effect sense — `text()` turns a failed spawn into an empty string — so `Effect.cached` happily memoised a degraded `unknown`, silently disabling upgrade and blocking uninstall until restart. The identity now distinguishes "the manager answered and we are not in its tree", which is durable, from "the manager did not answer", which is not, and retries only the latter. Found while reviewing those fixes, before pushing: * A naive `if (unprobed) recompute` would have re-spawned the manager on every call for anyone whose manager genuinely is not installed — on a path that runs at every startup check. The retry is itself memoised, giving exactly one extra attempt shared by all callers, with no check-then-act window. * `uninstall` still carried a `?? "@altimateai/altimate-code"` default — the same silent substitution that made an earlier revision delete a user's data and then remove a package that was never installed. It is unreachable today, because a package-manager method is only returned once ownership is confirmed, but the shape is the bug. A managed method with no confirmed package now refuses and prints manual steps. * Recovery guidance printed `@latest` regardless of what was asked for; it now echoes the requested target. Tests: non-exact targets (`latest`, `beta`, `^0.12.0`) are not reported as failures, while an exact target that does not match afterwards still fails; a sibling package's transitive platform dependency is not ours, and a hoisted one is.

Round-4 findings addressed in cc57ee1 — replies on all three inline threads. The minor is fixed too: recovery guidance now echoes the requested target instead of always printing Both "Missing Tests" are in: non-exact targets ( On the round count. This is the tenth pass and the pattern has been consistent: each round fixes real bugs and introduces smaller ones, because I was testing every new mechanism against the complaint that prompted it and never against itself.

Consensus Code Review — Round 5 — Claude + GLM-5.1 + Qwen 3.6 + MiniMax M2.7
Quorum not met, but strong convergence. Panel is Claude + 7 external models (quorum = 6). 4 of 8 produced usable output this round — all four reaching the same verdict independently, including on the one point of genuine technical nuance carried over from round 4 (the virtual-store attribution gap). Gemini 3.1 Pro (Antigravity) and GPT 5.4 Codex ran for 10+ minutes with real, growing CPU usage but never produced output; Kimi K2.5 and MiMo V2 Pro were both still actively exploring without reaching a conclusion and were stopped after an extended wait. Given the unanimous agreement among everyone who did finish, confidence in this round's verdict is high despite the shortfall.
Round-4 Fix Verification — all 3 confirmed FIXED
| # | Round-4 issue | Status | Evidence |
|---|---|---|---|
| 1 | CRITICAL — altimate upgrade latest/tag/range always misreported success as failure |
FIXED | const exactTarget = semver.valid(normalize(target)) !== null; const contradicted = exactTarget && after !== "" && ... — a non-exact target now logs "not verified against it" instead of failing. The unrunnable safety check (binary genuinely can't start) is still checked independently. |
| 2 | MAJOR — ownerOf() could attribute an unrelated package's hoisted transitive dependency to a coincidentally-present wrapper |
FIXED | Replaced "merely under the manager's root" with a placement check: the first path segment must be @altimateai (hoisted) or dot-prefixed (virtual store). New regression test covers exactly the reported scenario. |
| 3 | MAJOR (disputed) — Effect.cached permanently caches a degraded "unknown" result from a transient failure |
FIXED | Two-layer Effect.cached design: a new unprobed flag distinguishes "the manager genuinely didn't answer" (retried once, memoised) from "the manager answered and we're not in its tree" (a durable fact, cached immediately). Race-free, exactly one extra attempt shared by all callers. |
Round 4's MINOR (recovery guidance ignoring the requested target) was also fixed in this same commit — cli/cmd/upgrade.ts now interpolates args.target instead of always showing @latest.
Verdict: APPROVE (one suggested documentation addition, no code changes required)
No CRITICAL or MAJOR issues survive this round — the first round where the panel converges on "ready to merge."
Suggested Follow-ups (non-blocking)
1. Document the pnpm virtual-store attribution limitation — packages/opencode/src/installation/index.ts:156-179 (ownerOf)
An automated reviewer raised a real follow-up to round 4's fix: pnpm's content-addressed virtual store names entries by <package>@<version> globally, not scoped to which top-level package required them — so an unrelated package sharing the exact same platform-package version would land at the identical .pnpm/... path. All four reviewers independently agree: the mechanism is real, it's a fundamental limitation of path-based heuristics (a definitive fix would require reading pnpm's lockfile), and the blast radius is narrow and non-destructive (it always lands on a real, legitimately-installed wrapper, and the existing present.length === 1 guard already refuses to act when genuinely ambiguous).
Suggested comment:
// NOTE: pnpm's virtual store deduplicates identical pkg@version entries globally, so this
// cannot distinguish "our wrapper's dependency" from an unrelated package's dependency that
// happens to share the same platform-package version. A definitive answer would require
// reading pnpm's lockfile. The present.length === 1 guard below is the accepted mitigation.2. virtualStore accepts any dot-prefixed segment, not just known store directories — index.ts:174
const virtualStore = first.startsWith(".") && first !== "." && first !== ".."Tightening to /^\.(pnpm|yarn|bun)(?:$|[\\/])/.test(first) would remove one degree of freedom from the heuristic. Low priority — narrower than #1.
Positive Observations
- The
semver.valid()gate is precise: narrows scope to exactly the problem without weakening theunrunnablesafety check. - The two-layer
Effect.cachedretry design is notably elegant — exactly one extra attempt, shared by all callers, no check-then-act window. - The regression test for the hoisted-misattribution fix targets the exact reported scenario, not a simplified stand-in.
- Across all five rounds, the test suite has consistently been reviewers' most-cited strength, and this round's additions continue that.
- The author's replies throughout this review chain have been precise about root cause rather than defensive — part of why five rounds converged this cleanly.

The bug
Installation.method()never established where the running executable came from — it guessed, two ways, and both were unsound.1. Substring test on
process.execPath.~/.local/binis a generic user bin directory, not a marker of a standalone install. Withnpm config set prefix ~/.local— a common way to avoid needingsudo— an npm install was classifiedcurl, soaltimate upgraderancurl … | bash, wrote a standalone binary, and left the npm-managed copy stale and orphaned. Two installs then coexisted and PATH order decided which ran.2. A probe loop that asked the wrong question.
npm list -g,brew list, etc., returning the first manager whose output mentioned the package. That answers "is this installed anywhere?", not "did this running binary come from you" — so with more than one install present the result was effectively arbitrary, and upgrades targeted an install the user was not running.On top of that, the in-app Update now button could never succeed on a root-owned npm prefix:
upgrade()shelled out as the current user with no writability check, npm failed withEACCES, and the error surfaced as a genericUpgrade failed for npm (exit code 243).The fix
resolveInstall()— resolve, don't guess. Resolvesrealpath(process.execPath)and matches the package segment. The npmbin/altimateshim is a Node script thatspawnSync()s the per-platform package, so inside the CLIexecPathis:i.e. it always lands under
node_modulesfor every package-manager install. The optional-<platform>-<arch>suffix is matched explicitly rather than relying on the wrapper name happening to be a prefix of the platform package name. Homebrew is matched on theCellarsegment (not the prefix —/usr/localcollides with a common npm prefix), and.local/binis gone.This removes up to seven subprocess spawns from the startup update-check path; the new resolver spawns nothing.
Writability preflight. An upgrade that cannot succeed is now refused before shelling out, naming the directory and the exact remedy:
Uses
npm root -grather than<prefix>/lib/node_modules(Unix-only — Windows puts packages at<prefix>/node_modulesand shims at<prefix>), and derives the bin dir fromnpm prefix -gbecausenpm bin -gwas removed in npm 9. pnpm/yarn check both the root and the bin dir, since a global install writes both. brew/scoop/choco are skipped — their tooling owns elevation.A directory that does not exist yet is not a permission problem, so only an existing unwritable directory blocks.
Non-permission failures are now diagnosable. The failure branch had an asymmetry:
The real diagnostic output was logged on success and discarded on failure. So network loss,
E404,ENOSPCor a failing lifecycle script all collapsed into the same opaque message with nothing written anywhere, and telemetry got the generic string too — every failed upgrade looked identical on a dashboard.Now: the real stdout/stderr is logged locally (the log file never leaves the machine, and the success path already wrote the same content), the user-facing message adds a classified hint plus a pointer to the log, and telemetry records a stable code (
permission,network,not-found,disk-full,no-matching-version,unknown) with the exit status. The user-facing message and the telemetry payload stay redacted — stderr is never echoed into either.Not included, deliberately
No auto-
sudo. A TUI cannot host an interactive password prompt safely,sudo npm install -gruns package lifecycle scripts as root, and it would let a network-sourced version check trigger root-level writes. The message tells the user what to run instead.Tests
