[BUG] [v0.0.7] cortex update subsystem ignores CORTEX_HOME and writes update.json/update_cache.json under ~/.cortex

Project

cortex

Description

The update subsystem ignores CORTEX_HOME and uses HOME/.cortex for both persistent update files:

update_cache.json from the upgrade check path
update.json from the update config path

This creates split state. The CLI help explicitly documents CORTEX_HOME as the config directory override, but the update subsystem bypasses it and writes under ~/.cortex instead.

Error Message

No explicit error is shown. The bug is silent state being written to the wrong directory.

Steps to Reproduce

Set HOME and CORTEX_HOME to different directories.
Run:
HOME=/tmp/cortex-repro-home CORTEX_HOME=/tmp/cortex-repro-config cortex upgrade --check --yes --channel stable
Inspect both directories.
Observe that update_cache.json is created under HOME/.cortex/update_cache.json and nothing is written under CORTEX_HOME.
For the config-writing path, run the targeted proof:
cargo test -p cortex-update --test update_config_home_override -- --test-threads=1 --nocapture
Observe the test passes only because UpdateManager::skip_version() writes update.json under HOME/.cortex/update.json and not under CORTEX_HOME/update.json.

Expected Behavior

All update subsystem state should respect the active Cortex home override. If CORTEX_HOME is set, both:

update_cache.json
update.json

should be stored under that override rather than hardcoded HOME/.cortex.

Actual Behavior

The update subsystem uses dirs::home_dir().join(".cortex") directly:

UpdateConfig::load() / save() use HOME/.cortex/update.json
VersionCache uses HOME/.cortex/update_cache.json

As a result, update-related state is split away from the configured Cortex home.

Additional Context

Relevant source paths:

src/cortex-update/src/config.rs
- UpdateConfig::load() uses dirs::home_dir().join(".cortex").join("update.json")
- UpdateConfig::save() writes to dirs::home_dir().join(".cortex").join("update.json")
src/cortex-update/src/version.rs
- VersionCache uses dirs::home_dir().join(".cortex").join("update_cache.json")
src/cortex-cli/src/upgrade_cmd.rs
- UpgradeCli::run() creates config via UpdateConfig::load()
src/cortex-update/src/manager.rs
- check_update_forced() writes the cache
- skip_version() / clear_skip() write update.json

This is adjacent to, but not the same as, #51572 ("Config command ignores custom Cortex home path"). That issue is about the config command handler. This report is specifically about the cortex-update subsystem using its own hardcoded HOME/.cortex paths.

❌ Validation Summary — Issue #53527

Code verification failed: The code confirms the bug exists: the update subsystem hardcodes ~/.cortex instead of respecting CORTEX_HOME. However, the bug report does not contain any valid screenshots. The provided screenshot URL is a local file path (/tmp/cortex-cortexhome-bug-evidence-clean.png) which is inaccessible. Since valid screenshots are mandatory, the bug must be rejected.

Confidence Score: 4/5

This issue does not meet the minimum requirements for a valid bounty submission.

Adding the requested screenshot evidence here so the report has an inline visual repro artifact.

This screenshot combines:

the runtime upgrade --check repro showing update_cache.json written under HOME/.cortex
the targeted proof showing UpdateManager::skip_version() writes update.json under HOME/.cortex rather than CORTEX_HOME
