src/search/ranking.py computed result age as `(datetime.now() - dt).days`, where
`dt` is parsed from a UTC-style published date with no timezone. Using local
`datetime.now()` skewed the age by the host's UTC offset (off-by-up-to-a-day near
boundaries), and was a latent crash: once neighbouring code becomes timezone-aware
the naive/aware subtraction raises TypeError (the landmine called out in #1116).
Recency is now measured against naive UTC. The scoring is also lifted out of the
rank_search_results closure into a module-level, time-injectable `recency_score`
so it's unit-testable, and `_utcnow_naive()` avoids `datetime.utcnow()` (removed in
Python 3.14).
Covered by tests/test_search_ranking_recency.py (5 cases); the existing
tests/test_search_ranking.py still passes.

The agent soft-trims input context to `agent_input_token_budget` (default 6000).
The old computation `min(context_length or budget, budget)` made the 6000 default
a hard ceiling for every model, so 128K/1M context models were silently capped at
6000 input tokens — now that num_ctx is sent correctly (#1056), this was the last
barrier to actually using a long context window.
This derives the default budget from the model's discovered context window
(~85%, capped at a generous hard max) while honouring an explicit user setting
exactly (clamped to the window). When the window is unknown it falls back to the
previous value, so behaviour is unchanged for that case.
- src/context_budget.py: pure `compute_input_token_budget()` (unit-testable)
- src/settings.py: `is_setting_overridden()` to tell an explicit user value from
the merged default (load_settings merges DEFAULT_SETTINGS, so equality alone
can't distinguish them)
- src/agent_loop.py: use the helper in the soft-trim path
Covered by tests/test_context_budget.py (6 cases).

POST /api/embeddings/endpoint takes a user-supplied URL and immediately
makes an outbound httpx request to it with no validation. The admin gate
added earlier (PR #80) closed the unauthenticated-access part of #132; this
addresses the remaining request: validate the URL before fetching it.
Odysseus is local-first, so pointing the embedding endpoint at a loopback or
LAN server (local vLLM / llama.cpp / Ollama) is a normal setup — a blanket
private-IP block would break the primary use case. So the guard:
- always rejects non-HTTP(S) schemes (file://, gopher://, ftp:// …),
- always rejects the link-local range (169.254.0.0/16, incl. the cloud
instance-metadata 169.254.169.254 exfil vector) plus multicast /
reserved / unspecified, and IPv4-mapped-IPv6 forms of the above,
- keeps loopback/LAN allowed by default, and
- adds EMBEDDING_BLOCK_PRIVATE_IPS=true for full SSRF lockdown on exposed
multi-tenant deployments.
Logic lives in src/url_safety.py (stdlib only, resolver injectable) so it is
unit-testable without real DNS; the route calls it before the health-check
request. Covered by tests/test_url_safety.py (8 cases).

/api/health is a liveness ping. This adds /api/ready as a readiness /
integrity self-check that returns 503 unless every critical subsystem is
whole, so an orchestrator (Docker/Compose/k8s) can gate traffic on real
readiness rather than mere process liveness:
- database: opens a connection and runs SELECT 1
- data_dir: confirms the data directory exists and is writable
- local_first: reports whether storage stays on the host (informational;
a remote database is a valid deployment, so it never fails readiness)
The check logic lives in src/readiness.py so it is unit-testable in
isolation; the route is a thin wrapper. Covered by tests/test_readiness.py.
