gpt-5.6 on the Codex backend answers a large turn with a server-side
`compaction` checkpoint and no message. The checkpoint rides the
`codex_reasoning_items` sidecar, so the interim assistant message looks
"replayable" and `interim_replayable` suppresses the continuation nudge.
But replayable is not the same as different. A checkpoint carries no
answer and no new instruction, and a replayed checkpoint makes
`prune_pre_checkpoint_items` drop every pre-checkpoint item. Measured on
a real 262-message session: the wire collapses from 489 items to 12 —
all 186 `function_call` / `function_call_output` pairs deleted — and
ends on an empty assistant turn. The model has nothing to answer, so it
returns another empty response; the next attempt sends the same bytes
(the provider's prefix cache reports 99-100% on the repeats) and returns
the same nothing. Three attempts later the turn dies with "Codex
response remained incomplete after 3 continuation attempts" and the
whole turn's work is lost.
Keep the first continuation bare — the model often just needs another
turn, and nudging immediately would cut multi-phase work short. Once
that bare retry has also come back incomplete, it is proven not to work
for this turn, so every remaining attempt carries the nudge.
Folded from PR #98345 (@ericmaddox): the one scenario its suite covered
that #91557's did not — an assistant message between the image-only user
message and the checkpoint, asserting post-prune ordering.
Preserve valid normalized input_image user messages across native-compaction checkpoints at bounded one-token retention cost. Keep text extraction text-only, reject malformed or unknown multipart placeholders, and prove the production adapter path without claiming unsupported input_file behavior.
Republish the identical source tree after an unrelated nondeterministic focus-redraw test failure; this commit contains no source delta from the previously verified object.

* feat(compaction): always rebuild the system prompt at the commit boundary — keep-prompt now gated on byte equality of the LIVE builder output; plugin sections re-render with fail-open to last good bytes
* feat(clock): 'Conversation started' resolves through the session-lineage ROOT — a compacted/rotated session keeps its original birth date (Bot Mode forever-chats know when they were first born)
* test: retire old-contract pins — plugin sections re-render at invalidate (freeze stays restore-only), commit boundary always runs the live builder, byte-equal keep preserves object identity
Follow-up hardening on the two cherry-picked contributor commits:
- try_activate_fallback: replace the blanket request_overrides.pop('extra_body')
with KEY-SCOPED removal — only keys the OLD provider's custom_providers
entry contributed (value unchanged since the init-time merge) are dropped.
Caller/profile-provided extra_body keys survive the swap, matching the
caller-over-provider precedence in agent_init._merge_custom_provider_extra_body.
The fallback provider's own extra_body is then merged back in.
- switch_model: the live _primary_runtime snapshot it rebuilds now carries
request_overrides, so a post-switch transport recovery or fallback restore
reinstates the switched-to identity's overrides instead of dropping them.
- Tests: activation-level stale-key removal + caller-override preservation
(test_provider_fallback.py), switch-then-recover / switch-then-restore
(test_primary_runtime_restore.py).
Cache-safety: none of these paths mutate past context or rebuild the system
prompt — only outbound request kwargs change.
Fixes#75091
Profiles can now grant narrowly scoped tools to the background review runtime whitelist while unrelated tools remain denied. Document the configuration and cover it with a real-config regression test.
Agent: codex
Salvaged from PR #97815 by @itsflownium, slimmed to the schema-free core:
- TodoStore gains a monotonic in-memory revision; the todo tool result
returns it so clients can reject stale updates
- tui_gateway emits a dedicated todo.updated full-snapshot event that
bypasses optional tool-progress display settings
- session resume/activate responses attach the authoritative todo
snapshot; renderer restores it with revision arbitration
- desktop store tracks per-session revisions and rejects regressions
The session_todo_state DB table from the original PR is intentionally
dropped: canonical todo tool results already persist in conversation
history, so resume paths derive the snapshot from the stored transcript
instead of a parallel store.
The self-improvement review fork advertises the parent's full tool schema
(deliberate — tools[] must stay byte-identical for prompt-cache parity)
but denied everything except memory/skill tools at dispatch. Models
naturally reach for read_file to inspect a SKILL.md before patching, got
denied, then attempted a blind skill_manage patch which the
read-before-write guard correctly refused. One deployment logged ~142
denials + ~204 refusals over 2 days: the self-improvement loop ran
continuously but almost never landed a skill patch.
Fix is dispatch-side ONLY — zero request-body change, cache untouched:
- Whitelist read_file + search_files on the review fork (reads are
side-effect-free). Write tools (write_file/patch/terminal) stay denied:
autonomous maintenance must go through skill_manage's validation.
- read_file now registers full reads with the review fork's
read-before-write guard (same as skill_view), so the natural
read_file -> skill_manage(patch) sequence lands. Partial reads
(offset>1 / truncated) don't count. No-op outside review forks.
- Self-correcting deny message: names skill_view/skill_manage/memory as
substitutes so one denial redirects the model instead of a storm
(the actionable half of #61521's proposal 2).
Rejects #39997's alternative (narrow the advertised schema on local
endpoints): local backends have KV/prefix caches too, and re-prefilling
a large snapshot is most expensive exactly there.
Live A/B (real dispatch path, isolated HERMES_HOME): on main,
read_file DENIED -> patch REFUSED (read-before-write); on this branch,
read_file OK -> patch LANDED. tools[] identical in both.
The rename sweep in the base commit missed the sibling-test blast radius
(18 red files on CI). Three classes, all fixed:
1. Stale old names in tests (todo/cronjob/process/tour/tip) — updated to
todo_list/cronjob_manage/process_manage/gui_tour/show_tip at every
registry.get_entry/dispatch/coerce/preview/allowlist call site, plus
the coding-brief sentence in agent/coding_context.py now names
todo_list (and its gating test).
2. Missed rename in production: AGENT_RUNTIME_POST_HOOK_TOOL_NAMES still
held 'tour' — post-hook ownership would have double-emitted for
gui_tour via the bridge path.
3. Tests pinning pre-deferral assembly (blank-slate surface, modal
sandbox resolution, desktop diet, HUD note) now pin their ACTUAL
contract under the legacy defer:[] override, or assert on granted
tool names instead of visible schemas.
Also fixes a pre-existing ordering flake surfaced by the sweep:
test_holds_exactly_the_gui_affordances depended on whether an earlier
test had imported apply_layout_tool (registry-registered, not in the
static desktop_ui list) — now forces discovery and pins the full set.
649 tests green locally across all touched files, both orderings.
Closes#75364.
`_compress_context_via_codex_app_server` returns the transcript unchanged
when the codex thread reports `interrupted` or `error`. The session is
therefore still above threshold, and nothing records that the attempt
failed — so the next turn retries immediately, and keeps retrying for as
long as the condition persists.
Every other compression path arms the shared failure cooldown, records an
ineffective-compression strike, or both. This path records neither:
* `_hygiene_compression_failure_cooldowns` is set only on
`asyncio.TimeoutError`, or behind `_last_compress_aborted`, which is
assigned exclusively in `context_compressor.py` on the Hermes summarizer
path.
* `compression_ineffective_count` lives in `ContextCompressor`, and this
path returns before any compressor bookkeeping runs.
`compress_context` already documents the rule this path was missing —
"Every automatic entrypoint must honor compressor-owned cooldown and
breaker state" — but the codex branch dispatches above that block and
returns from inside it.
`result.interrupted` needs no unusual configuration to occur: an ordinary
user message arriving mid-compaction sets it (see
`codex_app_server_session.py`, which produces the "compact turn
interrupted" string). Observed in production on a Discord gateway session
at ~315k tokens against a 258k window, where compaction was attempted on
essentially every turn for ~70 minutes; the session's
`compression_ineffective_count` was still 0 afterwards.
This reuses the existing cooldown rather than adding a new mechanism:
* arm `_record_compression_failure_cooldown` with the existing
`_SUMMARY_FAILURE_COOLDOWN_SECONDS` when compaction returns
interrupted/error;
* honor an active cooldown on entry, matching the Hermes path.
`force=True` bypasses both, so an explicit /compress is never braked by a
failure it did not cause, and a successful compaction arms nothing.
- Preserve streamed assistant text in Desktop UI when message.complete delivers empty text.
- Prevent destructive hydration in Desktop useMessageStream over rendered text on empty completion.
- Recover stream buffer in finalize_turn when final_response is empty on healthy turns.
- Unify in-place blank assistant repair, watermark clone resolution, non-blank concurrent winner adoption, and batch row appends into a single atomic guarded SessionDB transaction.
- Synchronize canonical committed content to live in-memory messages dicts and preserve all-or-nothing rollback semantics on persistence failure.
The usage anchor (#97206) now trusts provider-reported usage. These two
tests simulated a tool-heavy near-overflow turn while the shared fixture
reported a 12-token prompt — the anchored pressure check honestly
concluded no pressure. Give the scenario 18K anchored prompt tokens so
the tests pin the same compaction decision they always did.
Every provider response carries usage.prompt_tokens — exact ground truth
for the full request (system prompt + tool schemas + history). Context-size
checks now anchor on the last main-loop response's usage and estimate only
the messages appended since, instead of re-estimating the whole history
with chars/4 heuristics and flat 1500-token image costs. The estimate error
window shrinks from the entire conversation to one turn and self-corrects
at every response.
- agent/model_metadata.py: capture_usage_anchor() / anchored_context_tokens()
with a structural base-message identity check that fails closed on any
transcript rewrite.
- agent/conversation_loop.py: anchor captured at the single main-loop usage
site (MoA uses pre-fold aggregator usage; advisor/aux calls never anchor);
pre-API pressure check prefers the anchor.
- agent/turn_context.py: preflight compression estimate prefers the anchor.
- agent/context_breakdown.py: /context display prefers the anchor.
- Invalidation: compaction rewrite (conversation_compression), codex native
compaction (codex_runtime), session reset/switch (run_agent), plus the
fail-closed structural check for splices/micro-compaction.
- Usage-less responses keep the previous anchor; no anchor -> pure
estimation fallback (first request of a session).
Pass 2 of repair_message_sequence matched results only by id/call_id,
pruning calls answered through response_item_id or composite bridge
ids. Use the shared variant helpers (tool_call_id_variants /
tool_result_id_variants) so the unified alias policy applies
(#55626/#63000/#93251).
The positional sanitizer pass changes the crash/resume duplicate shape:
an interrupted first occurrence is now stubbed instead of deduped, so
the replayed call survives with its own immediate result. Update the
#64335 empty-key test to the new semantics and add regression tests for
the #94704 acceptance shape (historical-result + replayed-call +
fresh-call) and the production interrupted-turn shape (session
7d57a602b83d).
DeepSeek v4 rejects a payload where an assistant message carries a
tool_call whose tool result does not follow it immediately (HTTP 400
"An assistant message with 'tool_calls' must be followed by tool
messages responding to each 'tool_call_id'"). Context compression can
displace a tool result past a user turn; the result then lands ~100
messages away from its declaring assistant message.
Two gaps let the poisoned shape reach the wire (reproduced from the
production request dump of session 4d8727cbcf04, replayed through both
functions):
1. repair_message_sequence Pass 1 drops the displaced tool RESULT as
stray but leaves the declaring assistant message carrying the now
unanswered tool_call (with empty content) in the durable history.
2. sanitize_api_messages stubbed only globally-absent result ids: the
displaced result still exists in the transcript, so the id survives
the set-subtraction, no stub is injected, and the payload 400s.
Fix both layers so every path is order-independent:
- repair_message_sequence: new Pass 2 prunes tool_calls that have no
result in the immediately-following tool run (matching on id or
call_id, same superset rule as Pass 1). If pruning empties the turn
(no content/reasoning left), the whole message is dropped rather than
sending an empty assistant message. Codex interim turns are exempt,
as in Pass 0.
- sanitize_api_messages: the orphan/stub logic is rewritten as a single
rolling positional walk that drops results not immediately following
their declaring assistant (including results appearing BEFORE their
call) and injects stub results for positionally-uncovered calls even
when a mispositioned result exists elsewhere.
Adds six regression tests: repair pruning, whole-turn drop when pruned
calls were the only payload, valid-pair negative control, positional
stub injection, result-before-call orphan drop, and a fully-paired
transcript negative control.
Rebased onto current main to drop the empty-tool_calls fix (already on
main via #86654, cherry-picked from #77944 with @webtecnica's
authorship). This PR now carries only the two fixes unique to it:
1. A pre-existing api_content sidecar left stale on the consecutive-
assistant merge. The sidecar takes priority over content at
API-build time, so a merge could silently discard its own freshly
concatenated content on the next call. Only dropped when the merge
actually changes the resulting value (wz-heng, #78063 review) --
content_rewritten compares before/after value, not just whether an
assignment branch fired, so a falsy new_content (e.g. "") that
strips to nothing no longer trips a spurious sidecar drop.
2. sanitize_api_messages never flagged a tool result with a missing/
empty tool_call_id -- its orphan-detection set only ever collected
truthy ids, so an unpaired result with no id passed the final
chokepoint untouched.
Addresses teknium1's rebase request and wz-heng's review findings on
_strip_images_from_messages() deleted any non-tool message whose content
became empty after image removal. An assistant message whose content was
entirely images but which carried tool_calls was therefore dropped,
orphaning its paired tool responses — providers reject the next request
with unmatched tool_call_id errors (HTTP 400). Replace such messages
with the plaintext placeholder instead, exactly like tool-role messages.
Adds a regression test covering the assistant + tool_calls +
image-only-content case.
Closes#40463
`api_content` is the byte-stability sidecar from #67274: it holds the exact
bytes previously sent for a message, and every turn substitutes it back into
`content` when building `api_messages`. `drop_stale_api_content` exists so a
content rewrite cannot be replayed from it — its own docstring states the
contract, and names the historical image strip as one of the callers:
Replaying the pre-rewrite sidecar would resend exactly what the rewrite
removed, so it must be dropped — the cost is one cache boundary miss,
never wrong content.
`_strip_images_from_messages` never drops it. The image-rejection recovery in
`conversation_loop` runs it over the persistent history, not just the per-call
copy:
agent._vision_supported = False
_imgs_removed = _strip_images_from_messages(messages) # history
if isinstance(api_messages, list):
_strip_images_from_messages(api_messages)
and `api_messages` are copies (`api_msg = msg.copy()`), so the history message
keeps its sidecar. The strip is therefore undone on the very next turn.
Reproduced with the real functions:
history content after strip : [{'type': 'text', 'text': 'look'}]
sidecar still present : True
NEXT TURN sends : 'look<IMAGE BYTES SENT LAST TURN>'
This is worse than a one-turn glitch, because the recovery cannot fire again:
it is gated on `getattr(agent, "_vision_supported", True)` and just set that
False. So on every subsequent turn the sidecar re-injects the images, the
text-only endpoint rejects them again, and the branch that would strip them is
disabled — the session stays wedged on a 4xx it already knew how to fix.
Drop the sidecar on each message the strip rewrites, inside the function so
every caller is covered. Messages with no images keep theirs, so only the
rewritten message pays a cache boundary — the tradeoff the invariant
prescribes. The two sibling recovery paths, `_sanitize_messages_surrogates`
and `_sanitize_messages_non_ascii`, are already safe: both walk every string
field on the message and so scrub the sidecar in passing. This one only
touches `content`.
tests/run_agent/test_image_rejection_fallback.py: new
TestStripImagesDropsStaleApiContent — the rewritten message loses its sidecar,
the next turn does not resend the stripped images, the tool-placeholder rewrite
is covered too, and untouched messages keep their sidecar. All four fail on
main. 53 passed across the image-rejection and api_content-sidecar suites; 307
passed across the sanitization/image/sidecar/replay agent tests (8 failures in
test_image_routing.py / test_save_url_image.py are pre-existing and fail
identically on clean main).
MiniMax's Anthropic-compatible endpoint rejects an oversized native image
part with "media exceeds size limit: max 10485760 bytes (2013)" — no
occurrence of the word "image", so none of _IMAGE_TOO_LARGE_PATTERNS
matched. The 400 fell through to _REQUEST_VALIDATION_PATTERNS (the body
is type: invalid_request_error) and classified as format_error /
non-retryable.
That skipped the image-shrink recovery in conversation_loop, which is
gated on FailoverReason.image_too_large. Because the oversized part is
already baked into history as a tool_result image block, and the context
compressor rewrites text but not image data, every later turn re-sent the
same bytes and failed identically — the session stayed dead until the
user forked it.
Match on the "media" fragment, mirroring the existing "image exceeds"
entry so reworded vendor variants are caught too. A non-image media
rejection routed here is safe: the shrink pass finds no image parts,
returns False, and the caller surfaces the original error unchanged.
Fixes#76039
Treat the ChatGPT Codex invalid image-data 400 as an image rejection so Hermes strips image parts and retries text-only instead of aborting the session. Add coverage for the exact error wording.
Truncated or corrupt image bytes baked into immutable conversation history
get re-sent on every retry. Kimi/Moonshot reject them with HTTP 400
'prepare image failed ... failed to decode image: invalid or unsupported
image format', which was missing from _IMAGE_REJECTION_PHRASES, so the
turn exhausted retries and wedged the session instead of stripping the
images and recovering.
Adds the phrase to the recovery list plus a regression test mirroring the
exact Kimi error body. Complements PR #76896 (proactive full-decode
validation in vision_tools) with reactive recovery for already-poisoned
sessions. Fixes#76884.
The observed wire error — 'Downloaded response does not contain a valid JPG, PNG, WebP, or ICO image.' — has no match in _IMAGE_CORRUPT_PATTERNS, so it falls through to the non-retryable 400 handler and the session replays the same image parts into the same 400 until /new.
Adds the full observed sentence to the pattern list. Deliberately not the shorter prefixes: a bare 'downloaded response does not contain a valid' also matches non-image 400s, and a negative test now pins that a downloaded-response certificate 400 keeps falling through to the existing handler. Covered on both the 400 path and the message-only path.
Reported by ryuhaneul in #69078.
The image_corrupt recovery stripped images from canonical messages, not
just the retry payload — a transient provider rejection (xAI 'Invalid
PNG image.') permanently erased history, breaking the copy-on-write
contract (e762a5a473). Strip only the per-call api_messages copy (its
rows are shallow copies; the strip replaces content instead of mutating
the shared parts list) and pin history isolation with two regressions
(#69104 sweeper review).

The prior commit removed the too-blunt generic fallback (any
non-retryable 400 with image parts present -> strip and retry), but
nothing in the test suite would fail if someone brought it back --
every existing test either targets a recognized image_corrupt wording
or has no image content in the request at all.
Add test_unrelated_400_with_image_parts_does_not_strip_or_retry:
same image-bearing setup as the positive recovery test, but the 400 is
an unrelated unsupported-parameter rejection with no image wording.
Asserts exactly one provider call (no retry), the error surfaces to
the caller, and -- the regression guard -- the single call's messages
still carry the image_url part. A reintroduced generic fallback would
strip it before surfacing this unrelated error, which is exactly the
P1 that got this design reverted in the first place.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Review (Sol xhigh) on the prior commit found a P1: the generic strip-
and-retry fallback ("any non-retryable 400 with image parts present
strips and retries") was too blunt. It couldn't tell an actual
image-corruption 400 apart from an unrelated one — bad tool schema,
unsupported parameter, billing, content policy — that merely happened
to carry image parts in the request. Any of those would silently erase
vision history and retry the still-invalid request, degrading sessions
that were never bricked in the first place. That's worse than the bug
it was meant to fix.
Revert the generic fallback (agent/conversation_loop.py). Keep only
the classifier-routed path: FailoverReason.image_corrupt +
_IMAGE_CORRUPT_PATTERNS, checked before _IMAGE_TOO_LARGE_PATTERNS
because shrinking corrupt bytes can't repair them. Corrupt-image
wordings still route to strip-and-retry; everything else falls through
to normal (non-retryable) handling as before. Add xAI's second wire
wording for the same corruption class ("base64 string of provided
image cannot be decoded", returned on unaligned truncation vs "Invalid
PNG image." on aligned truncation) and a compound-message test pinning
that image_corrupt wins when a body matches both pattern lists.
Drop TurnRetryState.stripped_images_this_turn. It's unnecessary now
that only one branch is left: the branch already only retries when
_strip_images_from_messages reports it removed something, and that
helper strips every image part from the request in one pass — so a
second corrupt-image hit on the retried (now text-only) request has
nothing left to strip and falls through on its own. No separate
one-shot flag needed.
Add a run_conversation integration test at the sequenced-provider
layer: corrupt 400 on attempt 1, strip, retry succeeds on attempt 2,
with explicit before/after assertions on the outgoing image_url part.

The permanent-brick class in #69078: xAI returns 'Invalid PNG image'
when a re-serialized image part in replayed history becomes
undecodable. The existing image-error patterns cover only Anthropic
'exceeds max dimension' wordings and 'model does not support images'
strings, so the classifier lands on a generic non-retryable 400 and
neither the shrink path nor the strip path fires. Every subsequent
turn (even bare text) fails identically because the poison stays in
history — the session is permanently wedged until deleted.
Two recovery layers, deliberately separate:
- Semantic split: new FailoverReason.image_corrupt with
_IMAGE_CORRUPT_PATTERNS ('invalid png image' / 'invalid jpeg image'),
checked BEFORE _IMAGE_TOO_LARGE_PATTERNS in both _classify_400 and
_classify_by_message. Corrupt bytes route to strip-and-retry, never
to the shrink path (shrinking corrupt bytes cannot help).
- Generic fallback: any non-retryable 400 whose outgoing messages
still contain image parts gets one strip-and-retry via the existing
_strip_images_from_messages helper, guarded by a new
stripped_images_this_turn one-shot flag on TurnRetryState. This
un-bricks the session for any current or future provider wording
without adding another pattern list to maintain.
Item 3 from the report (multimodal-part integrity across FTS
persistence + compaction handoff) is a separate investigation and
remains follow-up work.

When context-compression rotation fires mid-turn, the current user
message was persisted twice into the child session. Root cause: dedup
used id()-seeded sets of copies instead of markers on the live objects.
Replace with _DB_PERSISTED_MARKER-based dedup as the sole authority:
- _ensure_compressed_has_user_turn returns CompressedUserTurnOutcome
- After publish_compression_child succeeds, stamp the live anchor-source
row (not a drifted index) with _DB_PERSISTED_MARKER
- _sync_persisted_markers mirrors stamps from result to live lists by
scoped identity (handles direct-path, adoption divergence, _session_messages)
- Remove _flushed_db_message_ids from rotation commit path (markers replace it)
- Unconditional (loud) imports — no silent fallback
Salvage of #94996 by @fedosis, rebased on top of #95433 (stall-fallback,
already merged). Both conversation_compression.py and run_agent.py are
built from origin/main + #94996's diff applied on top, preserving the
force_terminal refactor and _publish_new_fence from #95433.
Credit: @fedosis original PR #94996.
Continuity tests pin tail_mode=legacy (they assert the raw LLM text
terminates the stored summary; lean's verbatim-user appendix follows it by
design and the contract under test is mode-independent). The #57491
rotation fixture grows 200→2000 chars/message: at ~2.5K total tokens the
old fixture fit entirely inside lean's 10K tail floor, so the no-growth
guard correctly refused the rotation the test exercises.
* refactor(prompt): remove the Nous Subscription block from the system prompt (~1.2K tokens/call)
* chore: retrigger CI (zero-job dispatch failure, auto-heal)
Per review: existing providers should not be retroactively re-versioned or
handed a changed payload. Version 1 is now the implicit historical
on_pre_compress() contract (best-effort, raw message list) that every
pre-existing provider is already on; the fail-closed checkpoint contract
becomes version 2. MemoryManager routes the raw transcript to v1 providers
unchanged and hands the host-normalized evidence list only to v2+ checkpoint
providers, so the plugin surface contract for shipped providers is
byte-identical with the gate off.
The skill_manage guard (added in #55906) refuses any patch/edit of an
existing SKILL.md, or overwrite/removal of an existing support file,
unless the exact target was loaded via skill_view during the review.
Neither _SKILL_REVIEW_PROMPT nor _COMBINED_REVIEW_PROMPT ever mentioned
this, so models routinely issued the write without the pre-read, got
refused, and burned review iterations (#62397).
Both prompts now carry a Read-before-write section scoped to the
guard's actual contract: existing targets only, exact-path pre-read for
support files, transcript quotes don't count, new skills/new support
files exempt, and a bounded one-view-one-retry recovery instead of a
loop. Direction follows #60331 by @kkwills13 with the scope corrections
requested in review (existing-target-only wording, no delete claim,
bounded retry, contract tests for both prompt variants).
Fixes#62397.
responses.create re-walks the entire request body against the
ResponseCreateParams union graph client-side while holding the GIL.
#93650 documents that walk wedging for 12+ hours on a ~1.4 MB
conversation, starving every other thread including the TTFB/stale
watchdogs — and no socket kill can unblock a pre-network hang.
Hermes payloads are JSON round-trips and already wire format, so the
bulk fields (input, tools) are now routed through extra_body, which the
SDK merges into the JSON body after the transform. Guarded by a
plain-JSON check (anything else keeps the typed path) and a
HERMES_CODEX_SDK_TRANSFORM=1 escape hatch. Applied to both the primary
stream path and the auxiliary adapter.

Follow-ups on top of the salvaged #92785 commit:
- Pre-gate now matches base URLs via normalize_route_base_url and
provider ids via custom_provider_aliases, mirroring the semantics of
get_custom_provider_model_capability. The raw string comparison
silently dropped declarations whose config spelling differed only by
host case or trailing slash (proven empirically: …/v1/ vs …/v1 with a
non-matching provider name returned (False, False) despite an explicit
prompt_caching: true).
- get_provider(..., allow_network=False) in the early-init/stub branch:
the policy runs per request destination (MoA aggregator, auxiliary
replans via blank_cache_policy_stub, early agent init) and a cold
models.dev cache triggered a measured ~450 ms foreground registry
fetch from the send path. A catalog miss degrades to the conservative
side.
- Debug-log the previously silent provider-lookup exception fallback.
- Tests: _make_agent defaults _custom_providers=[] (post-init reality;
keeps built-in-route tests off the catalog/config fallback), the two
early-init tests delete the attr explicitly, and three regression
tests pin the URL-drift, spaced-legacy-name, and no-network contracts
(all three fail on the unfixed commit).
