Inline comments:
In `@data_forecaster/.gitignore`:
- Line 21: Retain the .env ignore rule in .gitignore while keeping the
frontend/instance/ entry unchanged, so legacy frontend/.env files containing API
keys remain excluded from version control.
In `@data_forecaster/backend/core/llm_factory.py`:
- Around line 89-91: Update get_llm to validate that the Gemini configuration
API key is present before constructing ChatGoogleGenerativeAI, and raise
LLMConfigError when it is missing. Preserve the existing client construction for
valid keys.
In `@data_forecaster/backend/forecasting/indexing.py`:
- Line 38: Update the shared series-conversion helper used by the ARIMA, EWMA,
Holt-Winters, and SARIMA adapters so it does not replace an irregular
DatetimeIndex with positional RangeIndex values after dropna(). Reindex to the
declared frequency before fitting, or preserve the calendar gaps and reject
inputs when that frequency cannot be supported; keep the numeric values and
series name intact.
In `@data_forecaster/backend/forecasting/prophet_model.py`:
- Around line 97-99: Update _metrics_from_holdout to return non-finite
unavailable metrics, such as float("nan"), instead of (0.0, 0.0, 0.0) when
fitting or prediction fails. Apply the same default in the small-holdout branch
around the rmse, mae, and mape initialization, preserving valid computed metrics
and allowing _finite_metric to exclude unavailable results.
In `@data_forecaster/backend/main.py`:
- Around line 174-177: Update the fresh-install handling around require_api_key
and require_admin_api_key so that when setup is incomplete and API_KEY_ENABLED
is false, only setup status, POST /setup/bootstrap, and setup-required
configuration routes remain accessible; reject or gate upload, preflight,
analyze, job, and API-user administration routes. Preserve unauthenticated
bootstrap provisioning while leaving takeover protection as a separate concern.
In `@data_forecaster/backend/services/llm_validation_service.py`:
- Around line 105-110: Restrict the provider URL before the HTTP probe in the
LLM validation service: require http or https, reject embedded credentials, and
disable redirect following on AsyncClient. Add deployment-appropriate
DNS-resolved checks or an allowlist to block loopback, link-local, and private
address ranges, then reject invalid URLs before reporting reachability or
credential results.
In `@data_forecaster/backend/services/pipeline_service.py`:
- Around line 551-555: Update _select_model to validate forced_model against the
administrator-enabled model set, rejecting disabled values before selection. In
run_forecasting_agent, dispatch the selected Prophet model through the model
registry’s Prophet fitting path rather than the fallback fit_sarima branch, and
preserve the correct model-specific result and rejection metadata.
In `@data_forecaster/backend/services/setup_service.py`:
- Line 148: Update data_forecaster/backend/services/setup_service.py lines
148-148 around secret_store.generate_and_persist_key() to persist the encryption
key before committing the admin user and setup_complete state, so key-write
failures leave bootstrap retryable. Update
data_forecaster/frontend/blueprints/setup/routes.py lines 436-439 to avoid
treating a 409 as completed setup unless valid service credentials already
exist, and add an idempotent recovery path for bootstraps committed before
credentials were stored.
In `@data_forecaster/frontend/app.py`:
- Line 267: Remove "auth.login" from the pre-setup allowlist in the endpoint
authorization condition, while retaining "auth.logout" and the existing
post-setup behavior.
In `@data_forecaster/frontend/blueprints/admin/routes.py`:
- Line 1149: Update the model transition loop around client.put_model to process
enable transitions before disable transitions when replacing an enabled model.
Ensure the newly selected model is enabled before the currently active model is
disabled, while preserving existing behavior for independent updates.
In `@data_forecaster/frontend/blueprints/decorators.py`:
- Line 12: Split grouped imports into one import per line across all affected
sites: update data_forecaster/frontend/blueprints/decorators.py lines 12-12 to
import Callable from collections.abc and keep Any and TypeVar as separate
imports; split the WTForms imports in

imports in data_forecaster/frontend/blueprints/setup/routes.py lines 27-35;
split the setup-form imports there at lines 40-46; and split the API-client
imports there at lines 48-52.
- Around line 26-55: The get_backend_setup_status flow should distinguish an
unavailable backend from an incomplete setup instead of returning
setup_complete=False for connection errors, invalid responses, or non-200
statuses. Update _enforce_setup_complete to preserve completed setup when the
status probe is unavailable and report that condition with an appropriate 503
response, while retaining setup redirects/403 responses only for confirmed
incomplete setup.
In `@data_forecaster/frontend/blueprints/setup/__init__.py`:
- Line 3: Update the module header in the setup blueprint module to place the
required annotations future import immediately after the module docstring and
before the Blueprint import. Preserve the existing import and module structure.
In `@data_forecaster/frontend/blueprints/setup/forms.py`:
- Line 40: Update the relevant configuration field in the setup form to default
TLS certificate verification to True instead of False. Preserve the option for
operators to explicitly disable verification for local development or
self-signed certificates.
In `@data_forecaster/frontend/blueprints/setup/routes.py`:
- Line 82: Wrap the _render function signature so each line conforms to the
configured 88-character maximum, without changing its parameters, defaults,
annotations, or return type.
In `@data_forecaster/frontend/db/crypto.py`:
- Around line 43-45: Update the key-generation flow around _KEY_FILE to write
and fsync the complete key to a mode-0600 temporary file, then atomically
publish it without replacing an existing key created concurrently. On a
publication race, read and return the winning _KEY_FILE only after it is
complete, preserving the existing key-loading behavior.
In `@data_forecaster/frontend/services/api_client.py`:
- Around line 513-517: Protect the bootstrap flow used by the setup/bootstrap
request so unauthenticated clients cannot choose the initial administrator
credentials. Update the corresponding bootstrap route and client flow to require
a trusted channel or validated one-time bootstrap secret before invoking
run_bootstrap, while preserving normal first-run setup after successful
validation.
In `@data_forecaster/frontend/templates/main/forecast_setup.html`:
- Line 63: Update the forecast setup state and model selector so the enabled
model catalog is loaded and only administrator-enabled models are rendered;
remove or conditionally exclude disabled options such as Prophet while
preserving the current selection behavior for enabled models.

until non-empty content is available. Treat missing or whitespace-only content
as unavailable, using a shared _read_nonempty helper, so SECRET_KEY is never
initialized to an empty string during concurrent first-run writes.
In `@docs/deployment.md`:

documentation to export the variable before invoking Compose, or place the
assignment directly on the Compose command, so the child process receives the
configured hostname instead of falling back to localhost.

Keep the .env ignore rule.
The PR removes manual .env configuration, but config.py still reads frontend/.env as a legacy migration source, and existing deployments keep .env files that hold API keys. Without an ignore rule, a developer can commit those secrets.

The admin API can store a Gemini configuration with api_key=None. ChatGoogleGenerativeAI accepts this during construction, but its invocation then fails authentication. Callers return a generic error or use fallback paths. Raise LLMConfigError from get_llm before constructing the client.

Do not report 0.0 metrics for a failed or skipped holdout.
_metrics_from_holdout returns (0.0, 0.0, 0.0) when the fit or predict step fails. Line 146 uses the same zeros when the holdout split is too small. 0.0 is the best possible error value, so downstream selection treats a Prophet failure as a perfect model. _select_best_metric_model in data_forecaster/backend/agents/model_selection_agent.py (lines 791-808) selects by min(...), so Prophet wins the deterministic retry selection exactly when its metrics could not be computed.
Return nan (or inf) so the metrics are treated as unavailable. _finite_metric in the model selection agent already filters non-finite values.

Gate non-setup routes during fresh installation.
When setup is incomplete and API_KEY_ENABLED is False, require_api_key and require_admin_api_key return {}. This allows unauthenticated access to /upload, /preflight, /analyze, job routes, and API-user administration routes. Add a fresh-install guard that permits only setup status, bootstrap, and setup-required configuration routes. Keep POST /setup/bootstrap unauthenticated for provisioning; it requires separate takeover protection.

Protect POST /setup/bootstrap before first-run completion. The route has no authentication dependency. On a fresh database, run_bootstrap inserts the supplied credentials as the first administrator, then enables API authentication. Any untrusted client that can reach the published HTTPS port before setup completes can choose the administrator credentials. Restrict this route to a trusted channel or require a one-time bootstrap secret.

This static option remains selectable after an administrator disables Prophet. Load the enabled model catalog into the setup state and render only those models. Otherwise the user can select a model that the enabled-model policy rejects or ignores.
