Flip the two tests that pinned the old buggy behavior (rewrite_transcript
called after in-place compaction) to assert the corrected invariant from
#61145: archive_and_compact() already persisted, so the handler must NOT
call rewrite_transcript — its replace_messages(active_only=False) would
DELETE the just-archived rows.
E2E-verified against a real SessionDB: 6 soft-archived rows are wiped by
replace_messages' default path, confirming the data-loss premise.
When gateway session-hygiene auto-compression fires with in-place
compaction, the flow was:
1. _compress_context() calls archive_and_compact() — soft-archives old
rows (active=0, compacted=1) and inserts compacted messages as the
new active set. This is the non-destructive, durable path.
2. The hygiene handler then called rewrite_transcript() — which calls
replace_messages(active_only=False) — DELETEing ALL rows including
the just-archived turns. Silent permanent data loss (#61145).
The interactive /compress handler had the same bug.
Fix: only call rewrite_transcript() when session rotation produced a new
session id (legacy path). When in-place compaction succeeded, skip the
rewrite — archive_and_compact() already handled persistence.
Closes#61145.
test_accepted_at_every_position spawned 11 separate
'python -m hermes_cli.main' subprocesses, each cold-importing the full
CLI module tree under a 15s TimeoutExpired deadline. On a loaded CI
worker the import alone can exceed that (slice 2/8 flaked exactly here
on PR #61726's run, TimeoutExpired at subprocess.py:1253), failing PRs
that never touched the CLI.
Replace with ONE driver subprocess that imports hermes_cli.main once
and parses all 11 argvs in-process (catching SystemExit per argv),
reporting JSON results. Same assertions per argv, identical semantics
(verified the --help-before-unknown-flag exit behavior matches the old
method), ~11x less import work, and the 180s timeout only trips on a
genuine hang.
Structural completion of the malformed-job freeze fixes (#61382 id-less,
#61525 non-dict schedule, #61581 bad next_run_at): wrap the per-job body
of _get_due_jobs_locked in try/except so any FUTURE malformed-field
variant degrades to skipping that one job for the tick instead of
aborting the scan before save_jobs() and freezing the whole profile's
scheduler.
Also: restore test_repeated_concurrent_runs_accumulate_completed_count
to TestMarkJobRunConcurrency (accidentally re-parented by the #61581
diff), add a containment regression test, and AUTHOR_MAP for hydracoco7.
E2E: one jobs.json carrying all five malformed shapes (drifted job_id,
missing id, null schedule, garbage next_run_at, non-string last_run_at)
plus a healthy sibling — single tick contains all five, sibling fires,
repairs persist, second tick stable. 670 cron tests green.
One bad next_run_at value in jobs.json aborts the due-jobs scan with
ValueError from fromisoformat, before any save_jobs, so siblings lose
progress (fast-forwards etc).
Early normalization in _get_due_jobs_locked + defensive parses in
compute_next_run / _recoverable_oneshot_run_at.
Added test_bad_next_run_at_does_not_crash_or_block_sibling_jobs.
A job record in jobs.json can have a non-dict 'schedule' value (null, string,
etc.) from direct edit or old writers.
In _get_due_jobs_locked:
schedule = job.get('schedule', {})
kind = schedule.get('kind')
This (and direct schedule['kind'] in compute_next_run etc.) raises and
aborts the entire due-jobs scan before save_jobs() or advancing next_run_at
for healthy jobs. Exactly the same failure mode as the id-less job P1.
Fix: normalize non-dict schedules to {} early (before any use), matching the
defense added for id-less records. Also added defensive guards in compute
functions.
Added regression test that a bad schedule does not crash and healthy sibling
is still returned.
Refs similar pattern in #61382.
A cron record authored by a direct jobs.json edit that bypassed
add_job() can lack an "id" key (older writers used "job_id"). Every
site in _get_due_jobs_locked indexes job["id"] eagerly — both the
logging helpers (job.get("name", job["id"]) evaluates the default
argument unconditionally) and the 'for rj in raw_jobs: if rj["id"] ==
job["id"]' persistence loops. A single malformed record therefore
raised KeyError mid-tick, aborting the entire scan before save_jobs()
ran. Result: healthy jobs' fast-forwarded next_run_at was computed in
memory then discarded on the exception unwind, freezing the whole
profile's scheduler in a per-minute loop (observed dormant for weeks).
Fix: normalize id-less records at the top of _get_due_jobs_locked before
anything keys off job["id"] — recover the id from a drifted "job_id"
key when present, else synthesize one via uuid4, and persist. This
repairs the whole bug class at the source rather than guarding each of
the ~12 downstream index sites.
Adds a regression test that fails with KeyError on the current code and
passes with the fix, asserting a healthy sibling job is still returned
when an id-less record shares the store.
The salvaged fix sets HERMES_YOLO_MODE in main()'s dispatch path before
_prepare_agent_startup(); this follow-up also sets it inside
_prepare_agent_startup() itself so every launcher that triggers plugin/tool
discovery (incl. the Termux fast-CLI path) gets the same ordering guarantee
before tools.approval freezes _YOLO_MODE_FROZEN (#60328).
The HTML session export interpolated the tool-call name into the page
without escaping, while every sibling field went through _escape_html. A
tool-call name is attacker-influenced, so a prompt-injected model can emit
a name containing HTML that executes when the export is opened in a browser.
Escape the tool-call name like the other fields.
switch_model() unconditionally set agent.provider but only set
agent.base_url when the resolved value was truthy. When a real
provider change resolved an empty base_url (e.g. minimax after
copilot), the agent ended up with provider="minimax" but
base_url still pointing at api.githubcopilot.com. That incoherent
pair then got snapshotted into agent._primary_runtime, so it kept
re-applying on every subsequent turn via restore_primary_runtime()
until the process restarted.
try_activate_fallback() and _swap_credential() were audited and
confirmed unaffected: both always derive base_url from an actually
constructed client, never from a possibly-empty resolver hint.
Fix: when base_url is empty AND the provider is genuinely changing,
raise ValueError instead of silently keeping the old provider's URL.
This routes through switch_model()'s existing snapshot/rollback
path, and callers (tui_gateway/server.py's _apply_model_switch)
already catch and surface a clean "switch failed, staying on X"
message. Re-selecting the SAME provider with an empty base_url
(credential-only refresh) still keeps the current URL, unchanged.
Fixes#47828
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Port from openai/codex#31188: a parse failure in a policy-bearing config
file must not silently replace the effective policy with an empty/default
one. Codex's load_exec_policy_with_warning replaced the whole exec policy
with Policy::empty() when a .rules file failed to parse, silently dropping
managed prompt/forbidden rules; the fix preserves the managed policy while
still warning.
Hermes had the same bug shape in load_config(): a YAML parse error made
_load_config_impl() fall through to DEFAULT_CONFIG, dropping every user
override — including approvals.deny rules, which are documented to block
commands even under --yolo. In a long-running gateway, a user mid-editing
config.yaml into broken YAML silently disarmed their own deny rules on the
next load.
Now, when the process has a last successfully loaded config for that path
(_LAST_EXPANDED_CONFIG_BY_PATH), a parse failure keeps serving it (cached
under the corrupt file's signature so the broken file isn't re-parsed) and
the warning says edits are being ignored until the YAML is fixed. Fresh
processes with no last-known-good keep the existing DEFAULT_CONFIG
fallback and warning.
E2E-verified: deny rule 'curl*evil.com*' still blocks after mid-process
corruption; fixed file reloads normally; fresh-process fallback unchanged.
The earlier fix gated _resolve_use_tui, but the EARLY launcher
(_wants_tui_early) decides TUI from display.interface before cmd_chat
runs — so a `display.interface: tui` default still booted the Ink UI for
headless spawns (kanban workers), whose no-TTY bail-out exits 0 →
"protocol violation". Gate the early resolver on a real TTY: headless
stdio never boots the TUI regardless of config; explicit --tui still does.
Dragging a task done→ready did nothing: the respawn guard saw a run that
completed within the success window and deferred forever, unable to tell a
deliberate operator re-run from a status flap. Now a re-queue event
(status change, promote, unblock, reclaim) AFTER the completion bypasses
the recent_success guard, so an explicit done→ready runs again.
A retried task (→ running) kept showing "crashed Nx": the in-flight run
has no outcome yet, so the trailing crash scan skipped it and kept
counting the prior streak, and the consecutive_failures counter lingers.
Exempt `running` from both repeated_failures and repeated_crashes so a
fresh attempt clears the banner until it itself resolves (re-fires if the
new run also fails).
An inherited HERMES_TUI=1 or a `display.interface: tui` config default sent
kanban workers into the Ink TUI, whose no-TTY bail-out exits 0 without doing
the task — every attempt ended in "protocol violation". Two layers:
- _default_spawn pins `--cli` (highest-precedence interface flag) and strips
HERMES_TUI from the child env (covers older builds on PATH).
- _resolve_use_tui gates ambient TUI prefs (env/config) behind a real TTY;
an explicit --tui still wins so the informative bail-out stays reachable.
A manual done (dashboard/desktop drag) runs complete_task but ends no
run, so a trailing crashed/crashed run history never gains the
'completed' outcome that breaks the repeated_crashes streak — the card
kept flagging "needs attention" forever after being finished.
repeated_failures had the same hole via a stale counter. Terminal
statuses are now exempt from both: done means done; the history stays
on the event log for audit. Regression test included.
Adding the 6 gpt-5.6 slugs to DEFAULT_CODEX_MODELS grew the curated codex
catalog to 11, above the test's max_models=10 cap. That truncated the
picker list to 10 while total_models reported 11, breaking the
total_models == len(models) assertion. The cap was an implicit
change-detector on catalog size; raise it to 100 so the list is never
truncated and the count-consistency invariant stays meaningful as new
gpt-5.x slugs land.
Close the remaining end-to-end gaps so the full gpt-5.6 family (sol/
terra/luna + their -pro high-effort modes, 6 slugs) works on every
surface a user can reach them through:
- agent/auxiliary_client.py: the Codex OAuth backend hard-caps context
at 272K for gpt-5.6 exactly as it does for 5.4/5.5, but the default
50% compaction trigger would summarize at ~136K and waste half the
usable window. Extend the existing _is_codex_gpt54_or_gpt55 chokepoint
(single enforced predicate feeding _compression_threshold_for_model)
to match gpt-5.6* on the openai-codex route so those sessions get the
same 0.85 auto-raise. Direct-API/OpenRouter routes (full 1.05M window)
are unaffected; the historical codex_gpt55_autoraise opt-out still
applies. The one-time notice banner is model-dynamic and already
renders the correct slug/cap.
- hermes_cli/config.py, agent/agent_init.py: refresh the autoraise
comments/notice to mention the 5.6 family.
- hermes_cli/codex_models.py: add the -pro variants to DEFAULT_CODEX_MODELS
+ forward-compat so ChatGPT-OAuth (openai-codex) Pro users see the full
family in /model, not just the base tiers.
Supersedes the earlier commit's note that 5.6 was intentionally kept out
of the codex catalog: the slugs are confirmed routable (OpenRouter live
+ codex backend), so they belong there like every other codex-capable
gpt-5.x slug.
E2E verified across all 6 slugs: direct-API ctx 1.05M, codex ctx 272K,
pricing reachable from openai + openai-api routes, codex compaction
override 0.85 (and None on direct-API + when opted out), present in
openai-api picker + codex catalog, /model gpt resolves to sol on both
native routes. Guard tests added for the compaction route matrix.
Rerun scripts/build_model_catalog.py so the manifest is source-generated
rather than hand-edited (the -pro rows from the cherry-picked #61587 were
already correct; only updated_at changes).
PR #61587 adds sol-pro/terra-pro/luna-pro to the aggregator lists.
Complete those on the native surfaces the same way this PR completes
the base tiers:
- hermes_cli/models.py: -pro variants in _PROVIDER_MODELS[openai-api].
- agent/usage_pricing.py: alias ("openai", "gpt-5.6-*-pro") onto the
base-tier PricingEntry rows — the -pro high-effort modes bill at the
SAME per-token rates (verified against OpenRouter live pricing
2026-07-09: identical prompt/completion prices for base and -pro);
they cost more per task by consuming more tokens, not a higher rate.
- Context lengths need no new entries: "gpt-5.6-sol" et al. are
substrings of their -pro variants and both lookup tables match
longest-key-first (verified: sol-pro -> 1.05M direct / 272K codex).
- model_switch sort: -pro variants parse as suffix "sol-pro" (rank 1),
so /model gpt still defaults to base sol — pinned by test.
- Not added to DEFAULT_CODEX_MODELS: only confirmed routable via API/
OpenRouter so far; codex live discovery will surface them if ChatGPT
exposes them, same policy as other unconfirmed codex slugs.
Tests: invariant tests extended (pro aliases share base entries, base
sol outranks sol-pro); 191 targeted tests pass.
Phase-2 review findings addressed:
- resolve_billing_route: normalize the "openai-api" picker slug to the
"openai" billing provider — without this the ("openai", <model>)
_OFFICIAL_DOCS_PRICING keys (incl. every pre-existing gpt-4o/gpt-4.1
entry, not just 5.6) were unreachable when the provider is openai-api.
- pricing_version: drop the "preview" tag (GA 2026-07-09 at same rates).
- model_metadata comment: dict order is cosmetic — lookups length-sort
keys at match time; the old comment implied a positional invariant.
- model_switch comment: note "sol" is a series codename, not a generic
quality word.
- tests/hermes_cli/test_gpt56_registration.py: behavior contracts (no
list snapshots) — sol > terra/luna > 5.5 sort invariant, pricing
reachability from both openai and openai-api routes, cache-write
1.25x / cache-read 0.10x input relation.
PR #61578 added the GPT-5.6 series (sol/terra/luna) to the two aggregator
surfaces (OPENROUTER_MODELS, _PROVIDER_MODELS[nous]). This completes the
registration on the remaining surfaces per the standard add-model checklist:
- agent/model_metadata.py: DEFAULT_CONTEXT_LENGTHS 1.05M (direct API, same
as gpt-5.5; more-specific keys precede gpt-5.5 for longest-substring
matching) + _CODEX_OAUTH_CONTEXT_FALLBACK 272K for all three slugs.
Without these the direct-API fallback matched generic "gpt-5" = 400K.
- hermes_cli/codex_models.py: DEFAULT_CODEX_MODELS + forward-compat
templates so ChatGPT-OAuth (openai-codex) pickers surface the series.
- hermes_cli/models.py: _PROVIDER_MODELS[openai-api] (native API picker).
- agent/usage_pricing.py: _OFFICIAL_DOCS_PRICING snapshot — sol 5/30,
terra 2.50/15, luna 1/6 per 1M in/out; cache read 0.10x input, cache
write 1.25x input (OpenAI billing change starting with the 5.6 series).
GA 2026-07-09 at preview rates. Sol Fast mode (Cerebras tier) excluded.
- hermes_cli/model_switch.py: rank "sol" as a flagship suffix so
/model gpt resolves to gpt-5.6-sol, not alphabetical-first luna.
Verified: registry E2E via real imports (both context tables, codex
forward-compat from a gpt-5.5 template, billing-route lookup for
openai/gpt-5.6-sol -> 5.00/M), alias resolution on openai-codex and
openai-api resolves to gpt-5.6-sol; 183 targeted tests pass
(model_metadata, usage_pricing, codex_models, model_catalog).
hermes send "MEDIA:/x.png This Caption" now arrives as one native captioned
bubble instead of a separate text message followed by an uncaptioned bubble.
Root cause: the standalone senders (hermes send / cron / send_message tool)
stripped the MEDIA: tag, sent the remaining text as its own message, and
called the media send with no caption -- even though hermes send's help
advertises the captioned form and the bridges/adapters already support a
caption. Signal already captioned correctly.
- tools/send_message_tool.py: new _media_caption_split() chokepoint decides
caption-vs-separate-body (single captionable non-voice file within the
platform's message-length cap). Wired into the Telegram, WhatsApp and
Discord dispatch paths.
- Telegram/WhatsApp/Discord: when the single captioned file is missing, the
caption text is delivered as a plain message so it is never silently lost.
- Telegram caption send gets a MarkdownV2->plain parse fallback.
- Tests: _media_caption_split unit tests + per-platform caption tests
(ride, multi-file fallback, voice exclusion, over-limit fallback,
missing-file text fallback); updated the 3 tests that asserted the old
text-then-media split.
Closes the gap reported against #58911 (the MEDIA_CAPTION directive PR);
credit to @ferreiraesilva for surfacing the caption behavior.
Review finding: callers mutate the returned dicts in place —
hermes_cli/web_server.py annotates s['enabled']/s['usage'] on the skills
list — so handing out the cached objects poisons the cache for every
subsequent caller (and is a cross-thread shared-mutable hazard in the
gateway). Return [dict(s) for s in cached] on both hit and miss paths;
warm-path cost is negligible (241x speedup retained on a 300-skill
fixture). Regression test mutates a returned list/dict and asserts the
next cached call is clean.
Review findings on the cherry-picked cache (follow-up to #58985):
- The cache key was the max mtime of only the TOP-LEVEL scan dirs.
Adding/removing a skill inside a category subdir bumps the category
dir's mtime, NOT the root's, so the cache served a stale list
indefinitely. Replace with a per-dir signature covering roots +
immediate children (one scandir per dir; mirrors
hermes_cli/profiles.py::_count_skills from d5eee133e).
- The disabled-set is config-driven and changes with no filesystem
mtime bump; fold it into the signature so /skills disable takes
effect without a restart.
- Platform is part of the signature (gateway processes serve multiple
platform scopes; scan results are platform-filtered).
- Add a 30s TTL to bound staleness from in-place SKILL.md edits (file
mtime is invisible to any directory signature).
- The original also keyed dirs off the module-level SKILLS_DIR constant;
the scan itself uses _skills_dir() (live profile HERMES_HOME) — use
the same resolution for the signature.
Mutation-verified: nested-add, disabled-set, and TTL tests fail against
the pre-fix cache and pass with it.
_find_all_skills() re-reads every SKILL.md on every call, which is
wasteful when nothing changed between turns. Cache results keyed by
the max mtime across all scanned skill directories — a skill write
touches the directory, bumping mtime past the cached value and
triggering an automatic re-scan.
skip_disabled True/False are cached separately.
This commit is unstacked from #58984; it carries only the skill
discovery cache change.
(cherry picked from commit cd65673a8f)
The salvaged PR added a standalone test_reasoning_timeouts.py that duplicated
the structure of the existing parametrized test_reasoning_stale_timeout_floor.py.
Fold the v4-flash/v4-pro/-free positive cases and deepseek-chat negative cases
into the canonical parametrized tables and remove the redundant file.
DeepSeek V4 models (deepseek-v4-flash, deepseek-v4-pro) emit
reasoning_content in a separate delta field before final content,
requiring the same 600s stale timeout floor as R1. Without this,
streams hang for 30–50s with APITimeoutError on providers like
opencode-go while direct calls succeed in ~3s.
Fixes#60338.
Phase-2 review finding: the validation branch expanduser()s the path but
web_server.py reads os.environ['HERMES_WEB_DIST'] raw at import — a
'~/dist' value would validate here and still 404 there. Write the
expanded path back before the web_server import. Adds a regression test
asserting the env var holds the expanded path after cmd_dashboard.
Review finding: PR #40632's branch had silently dropped gemma-3-27b
from the keep-extra_content test loop (part of its Gemma narrowing,
which this salvage reverts). Restore main's original coverage so a
future narrowing back to Gemini-only fails loudly.
Trim the salvaged commit to its two still-valid conversions:
- ChatCompletionsTransport.convert_messages (copy-on-write sanitize)
- QwenProfile.prepare_messages (copy-on-write normalize + cache_control)
Dropped from the original PR:
- agent/prompt_caching.py selective-copy: superseded by #57229 which
already rewrites apply_anthropic_cache_control on current main.
- Gemma extra_content narrowing (_model_consumes_thought_signature
'gemini or gemma' -> 'gemini' only) + its two tests: unrelated
behavior change reverting deliberate e8c3ac2f5; belongs in its own
PR with its own justification if pursued.
Conflict resolution: preserved main's newer timestamp-stripping
(#47868) inside the copy-on-write path.
Mock _preflight_user_systemd and _select_systemd_scope in
test_systemd_start_refreshes_outdated_unit and
test_systemd_restart_refreshes_outdated_unit. These tests target
unit-file refresh logic, not D-Bus reachability, so the preflight
check was causing spurious UserSystemdUnavailableError on macOS,
WSL, and Docker where systemd is unavailable.
(cherry picked from commit 34113300a1)
A custom HERMES_WEB_DIST without --skip-build skipped BOTH the web UI
build and any validation: cmd_dashboard fell through the build gate and
started the server against a dist that may not exist, serving 404s with
no obvious cause. This is the same failure mode issue #23817 fixed for
the --skip-build branch — the env-var branch was left unvalidated.
Add the missing else-branch: fail fast with actionable guidance when
HERMES_WEB_DIST has no index.html, proceed (still without building) when
it does.
Credit: @Caelier (#17845) originally proposed dist validation for the
dashboard startup path; the --skip-build half of that PR's scope has
since landed via the #23817 fix, this covers the remaining env-var path
on the rewritten cmd_dashboard surface.
Two async handlers still called the cron profile-walk helpers directly on
the FastAPI event loop after the 49fa04a23/346e5673d threadpool migration:
- POST /api/cron/fire called _find_cron_job_profile() inline — it walks
every profile and lists its jobs (file I/O per profile), stalling the
loop before the 202 is returned.
- POST /api/cron/blueprints/instantiate called _call_cron_for_profile()
inline for create_job.
Route both through the existing _run_cron_dashboard_io threadpool wrapper
like every other cron dashboard endpoint.
Credit: @riceharvest (#50948) originally identified the sync-I/O-in-async-
handlers bug class for the desktop boot endpoints; 49fa04a23, 346e5673d,
7d0ddbb2f, d5eee133e and 24d5bda1e have since fixed most of that PR's scope
via the managed threadpool + PID cache + alias-map surfaces. This covers
the two cron handlers those merges missed.
Review finding: the substring check ('kimi' or 'moonshot' in model)
under-matches bare release slugs like k2-thinking that the repo's
canonical _model_name_is_kimi_family matcher (anthropic_adapter.py)
already covers. Reuse it instead of a second ad-hoc matcher; add a
regression test for the bare-slug case.
Adapted from PR #26014's test file to the canonical seam
(tests/run_agent/test_anthropic_prompt_cache_policy.py _make_agent
helper) instead of a new top-level file with sys.path manipulation.
Covers: kimi-k2.6 + moonshot-v1 on OpenRouter (envelope layout),
kimi via Nous Portal, and the non-OpenRouter negative case.
Kimi/Moonshot models on OpenRouter honour the same envelope-layout
cache_control markers as Claude on OpenRouter, but the policy fell
through to (False, False) — serving ~1% cache hits on 64K-token prompts
and re-billing the full prompt every turn. Observed within-turn
progression with cache enabled: 1% -> 67% -> 84% -> 97%.
(cherry picked from commit 3b857a35e, agent/agent_runtime_helpers.py hunk only;
the original PR #26014 branch also carried unrelated .dev-workflow artifacts
which are intentionally not included)
Structured review (2a/2b/2c) findings, all fixed:
- MAJOR: detect_local_server_type memo was process-lifetime with no
invalidation, permanently pinning a URL's server type. Now a bounded
1h TTL ((type, monotonic) tuples) so a backend swap on the same port
is re-detected. Test covers ollama->lm-studio swap after expiry.
- MAJOR: legacy disk-row compat was one-way. get_cached_context_length
and _invalidate_cached_context_length now consult the same key-shape
set {canonical, literal, canonical+slash} in both directions, so an
old slashed row is found (and cleared) when the runtime passes the
normalized URL. Tests pin both migration directions.
- MINOR: _localhost_to_ipv4 did whole-string replacement, which could
corrupt a proxy URL embedding http://localhost in its query. Now a
scheme-anchored host-only regex; localhost.example.com and embedded
substrings pass through. Tests added.
- MINOR: _invalidate_cached_context_length now also drops the
in-memory TTL probe rows for the pair, so a resolution inside the
TTL window can't re-persist the value just declared stale.
- Test gaps closed: detect-type cache hit + TTL-expiry re-detection,
ollama-show TTL expiry re-probe, reverse legacy-row lookups.
- Attribution gate: added zhchl@hermes-agent.local -> 8294 (PR #50572
author) to AUTHOR_MAP; the strict CI grep needs bare non-plus emails
literal in release.py.
Gates: ruff clean; targeted suites 202 passed / 0 failed; full
tests/agent 5426 passed with 17 failures identical on clean
upstream/main (pre-existing env-dependent anthropic/bedrock/credpool
tests); mypy delta vs base: 0 new errors; live smoke 6/6 PASS.
#37595 fixed the Windows dual-stack IPv6 timeout only inside
detect_local_server_type. The same 2s-per-probe penalty existed at every
other helper that builds a probe URL from base_url. Extract the rewrite
into _localhost_to_ipv4() and apply it at:
- query_ollama_num_ctx
- query_ollama_supports_vision
- _query_ollama_api_show (server_url derivation)
- _query_local_context_length (server root + LM Studio native URL)
Tests cover the helper's URL forms, non-localhost passthrough, and that
the ollama probes actually POST to 127.0.0.1.
