## Description
Add --request-timeout-seconds CLI flag and HEADROOM_REQUEST_TIMEOUT
environment variable to the headroom proxy command, allowing users to
configure the upstream request timeout (default: 300s). This is useful
for slow providers such as local LLM servers (Ollama, vLLM, llama.cpp)
where the default timeout may be insufficient.
Fixes#737
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- Added --request-timeout-seconds option to the proxy command with
HEADROOM_REQUEST_TIMEOUT envvar support

- Added tests for both CLI flag and environment variable paths
## Testing
- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)

- [x] New tests added for new functionality
- [x] Manual testing performed
### Test Output
```text
$ pytest tests/test_cli_proxy_env.py -q
45 passed in 3.46s
$ mypy headroom
Success: no issues found in 356 source files
$ ruff check .
All checks passed!

## Additional Notes
Follows the existing pattern used by --connect-timeout-seconds.
Environment variable approach is essential for Docker/Kubernetes
deployments where modifying CLI args requires image rebuilds.

## Real Behavior Proof
- Environment: GitHub PR metadata and checks for `chopratejas/headroom`
PR #738.
- Exact command / steps: Reviewed PR title, commits, changed files,
linked issues, labels, and check rollup; appended this maintainer
template completion block without replacing the author's original
description.
- Observed result: PR body now contains all required governance
sections, checked readiness fields, and a non-placeholder validation
evidence block.
- Not tested: This pass updated PR metadata only; code validation
remains represented by the linked GitHub checks and any author-provided
evidence above.

<!-- headroom-maintainer-template-completion:end -->
## Description
Anonymous usage telemetry was **on by default** (opt-out). This flips it
to **opt-in**: nothing is collected or shipped unless the user
explicitly turns it on. Small change, but it makes "no data leaves the
proxy by default" the actual default rather than something users have to
discover and disable.
Closes # <!-- N/A: no tracking issue -->
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality) — adds
`--telemetry` opt-in flag
- [x] Breaking change (fix or feature that would cause existing
functionality to change) — telemetry no longer runs unless opted in
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- `is_telemetry_enabled()` is now **fail-closed**: only explicit
on-values (`on`/`true`/`1`/`yes`/`enable`/`enabled`) enable telemetry;
unset, empty, or unrecognized values stay disabled. This single
predicate gates both the Supabase beacon and the local `/v1/telemetry`
collector.
- Added `--telemetry` opt-in flag to `headroom proxy` and `headroom
install apply`; kept `--no-telemetry` and `HEADROOM_TELEMETRY=off` for
back-compat. If both are passed, opt-out wins.
- Install manifests now write `HEADROOM_TELEMETRY` explicitly
(`on`/`off`) plus the matching flag, so generated systemd/docker/launchd
deployments are unambiguous and don't rely on the runtime default.
- Startup banner and proxy log show `DISABLED` by default and surface
how to opt in.
- Updated tests for opt-in defaults; added coverage for the default-off
banner, the `--telemetry` flag, and the explicit-on manifest path.
- Updated docs
(proxy/configuration/installation/benchmarks/community-savings mdx, spec
011/015, wiki proxy/cli/benchmarks/metrics) and `CHANGELOG.md`.
## Testing
- [x] Unit tests pass (`pytest`) — targeted telemetry + install-planner
suites
- [x] Linting passes (`ruff check`)
- [x] Type checking passes (`mypy`)
- [x] New tests added for new functionality
- [x] Manual testing performed
### Test Output
```text
$ python -m pytest tests/test_telemetry_warning.py tests/test_telemetry.py tests/test_install/test_planner.py -q
81 passed
$ ruff check <changed source + test files>
All checks passed!
$ mypy headroom/telemetry/beacon.py headroom/cli/proxy.py headroom/cli/install.py \
headroom/install/planner.py headroom/proxy/server.py
Success: no issues found in 5 source files
```
## Real Behavior Proof
- **Environment:** macOS (darwin 25.4.0), project `.venv`, `headroom`
CLI.
- **Exact command / steps:**
```
$ python -c "import os; from headroom.telemetry.beacon import
is_telemetry_enabled; \
os.environ.pop('HEADROOM_TELEMETRY', None); print('unset ->',
is_telemetry_enabled()); \
[ (os.environ.__setitem__('HEADROOM_TELEMETRY', v), print(repr(v), '->',
is_telemetry_enabled())) \
for v in ['on','TRUE','1','yes','off','0','garbage',''] ]"
$ headroom proxy --help | grep -i telemetry
$ headroom install apply --help | grep -i telemetry
```
- **Observed result:**
```
unset -> False # off by default
'on' -> True 'TRUE' -> True '1' -> True 'yes' -> True
'off' -> False '0' -> False
'garbage' -> False '' -> False # fail-closed
proxy: --telemetry Opt in to anonymous usage telemetry — off by default
(env: HEADROOM_TELEMETRY=on)
--no-telemetry Force anonymous usage telemetry off (already the default;
env: HEADROOM_TELEMETRY=off)
install: --telemetry Opt in to anonymous telemetry in the runtime (off
by default).
--no-telemetry Force anonymous telemetry off in the runtime (already the
default).
```
- **Not tested:** live Supabase beacon network round-trip (no opt-in
network call was made); full `pytest` suite was not run — only the
telemetry + install-planner targeted suites.

## Additional Notes
- "Breaking change" is checked because the default behavior changes
(telemetry stops running unless opted in). It is **not** an API break —
`--no-telemetry` and `HEADROOM_TELEMETRY=off` still work, so existing
opt-out configs are unaffected.
- No tracking issue, so `Closes #` is left N/A.
Document the proxy-side code-aware flags so the CLI reference matches the current wrapper and server behavior.
The wrapper now exposes the positive flag, and the server docs should show both enable/disable forms with the shared env var defaulting behavior.
