feat(residency): reconcile fork with Lemonade v11.7.0 by nisavid · Pull Request #101 · nisavid/lemonade

Summary

Reconcile the maintained fork with upstream Lemonade v11.7.0 while preserving portable residency, model protection, GPU-capacity admission, and deterministic recovery contracts. Merge 87267c85 preserves both the accepted fork history at 51e0ed91 and upstream v11.7.0 at 2b6a7d77; the source-ready binding at 70f91bec records this PR and its claim-by-claim revalidation evidence. The final published revision also hardens benchmark artifact handling and workflow permissions, makes TheRock runtime validation and cleanup method-specific, rejects unsafe local-import model names before cache-path derivation, closes configuration and backend edge cases, and aligns v11.7 package metadata.

Fixes #99

Review path

Start with protected admission, aggregate GPU-memory accounting, watchdog reload fencing, and exclusive-work drain in src/cpp/server/router.cpp and src/cpp/include/lemon/router.h, then review local-import registration validation in src/cpp/server/server.cpp, saved and transient recipe-option authority in src/cpp/server/model_manager.cpp, and CPU/GPU backend selection in src/cpp/server/backends/sdcpp/sdcpp_server.cpp.
Review configuration migration and model-label authority in src/cpp/server/runtime_config.cpp and src/cpp/resources/server_models.json, generated-surface reconciliation in docs/tools/gen_backend_boilerplate.py, and build/package closure in CMakeLists.txt and contrib/debian/control.
Review method-specific ROCm/TheRock discovery, installation, cleanup, and DLL staging in src/cpp/server/backend_manager.cpp and src/cpp/server/backends/backend_utils.cpp, then cross-platform backend selection and staging in src/cpp/server/backends/llamacpp/llamacpp_server.cpp and src/cpp/server/backends/sdcpp/sdcpp_server.cpp.
Review benchmark archive trust boundaries, cross-origin credential stripping, and workflow secret scoping in .github/scripts/validate_backend_bench.py, .github/workflows/benchmark-regression.yml, and .github/workflows/docs_and_style.yml.
Close on the residency and runtime regressions in test/cpp/test_router_model_lifecycle.cpp, test/cpp/test_gpu_memory_planner.cpp, test/cpp/test_therock_runtime.cpp, and test/test_validate_backend_bench.py, then the evidence roster and source-ready record in plan/evidence/source-revisions/v11.7.0/scout-revalidation-1.json and plan/evidence/source-revisions/v11.7.0/maintained-fork-binding.json.

…nce (lemonade-sdk#3103) The `## Models` section duplicated `server_models.json` as ~285 lines of markdown tables (58% of the file) that nothing links to. The user-facing catalog at lemonade-server.ai/models.html fetches `server_models.json` live from GitHub raw at the release tag, so it never read these tables. Every model-catalog PR had to rebuild lemond in the `backend-docs-drift` job and regenerate the doc, or fail CI — lemonade-sdk#2495 was a PR whose entire content was three table rows added to fix that failure. Removes the section, `render_models`, the now-unused `SERVER_MODELS` constant, and the `backend-models` marker region from the template. The descriptor-backed regions (overview, support matrix, recipe options) are unchanged; those are derived from C++ and genuinely need the drift check.

…onade-sdk#3111) * fix(alias): report the real reason for alias validation failures Alias handlers routed failures through create_model_error(), which rewrites its message whenever the name is absent from the registry — always true for a new alias — so every validation error reported "model not found" plus a list of unrelated models instead of the actual cause. The CLI compounded this: extract_server_error_message() only unwrapped string-shaped error bodies, so object-shaped ones (what the server actually emits) printed only "Request failed: <code>". That affected every CLI command hitting a structured error, not just aliases. Also corrects the Muse Glimmer post, which promised built-in availability on a specific weekday and date; it now refers to the version instead.

…del updates (lemonade-sdk#3073) * fix(server): compare artifacts, not commit SHAs, when checking for updates check_for_model_updates flagged an update whenever the upstream commit SHA moved, so a README-only commit -- or any commit touching an unrelated variant in a shared multi-artifact repository -- re-raised "Update available" on every restart. download_from_registry already handles this via can_reuse_previous_hf_snapshot; the startup check never called it. - Compare the per-model artifact set (resolved checkpoints, expanded across GGUF shard families) between the cached ref and the latest commit before advertising a re-download. - Gate on Hugging Face: ModelScope snapshots are tree fingerprints with no commit pin, so they keep the snapshot-id comparison. - Every indeterminate path (missing file, fetch failure, empty set) falls back to flagging an update, so a real update is never hidden. Fixes lemonade-sdk#2542 Co-authored-by: Claude Opus 5 <noreply@anthropic.com> * fix(server): track update-check baselines separately, share artifact selection with pull - compare artifacts against the on-disk snapshot (resolved path/refs main), never the processed-at-pull sha, which may name a snapshot never materialized locally - select artifacts from the new revision's tree via the same helper pull uses, so added-in-directory and tokenizer/config-only changes are detected - verify auxiliary checkpoints under their own repository entries; a model is verified only once every repository it spans completes a determination - an indeterminate repository (no resolvable local baseline) assumes changed instead of silently skipping, so it can no longer block another repository's completed determination for the same model - any indeterminate artifact check consistently assumes changed - move the per-model repository count into registry_files::DeterminationTracker, guarded against a model being marked determined twice for the same repository - compare the union of the previous and current revision's selected files, not just the current one, so a file removed upstream (e.g. from a directory checkpoint or a GGUF shard family) isn't silently dropped out of comparison - apply the same union fix to pull's own snapshot-reuse check (download_from_registry), which shared the identical blind spot independently of this update-check path Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> * fix(server): keep same-repo auxiliary checkpoints in pull snapshot reuse * test(server): stale provenance snapshot must not flag a false update --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

…sdk#3052) * ci: stop building unused targets in the validate workflows The llama.cpp and vLLM validate jobs built every CMake target; both only need lemond (plus the CLI for sd.cpp/vLLM). Cache build/_deps in the three validate jobs and drop the `Remove-Item build` that would have deleted the restored cache. - validate_llamacpp: all targets -> lemond, BUILD_WEB_APP=OFF, _deps cache - validate_sdcpp: _deps cache, drop build/ wipe - validate_vllm: all targets -> lemond lemonade, _deps cache - actions/cache v4 -> v5 in the Windows embeddable job Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * ci: address review on the validate build caches - vLLM: install build deps directly instead of ./setup.sh, whose "Preparing build directory" step rm -rf's the restored _deps cache - share one _deps cache between the two Windows validate jobs rather than writing one each; the repo is near the 10 GB Actions cache cap - add toolchain/runner-image markers and cmake/*.cmake to the cache keys - verify build/lemonade in the vLLM build job - finish the action-version bump in the Windows embeddable job Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Revert "ci: bump action versions in the Windows embeddable job" The embeddable job neither builds validate targets nor shares a cache with them, so the action-version bumps do not belong in this PR. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * ci: drop the _deps cache from the validate workflows The warm-cache rerun showed it does not pay for itself: 2 of 3 jobs missed even though the prior attempt had saved both keys 14 hours earlier (the repo's Actions cache is at its 10 GB cap, so ~550 MB entries are evicted within hours), and the job that did hit got slower. Configure dominates these builds and reconfigures either way, leaving a ~30s ceiling on a 10-minute job. Also reverts the two changes that only existed to protect the cache: the `Remove-Item build` deletions and vLLM's direct apt-get install in place of setup.sh.

…dk#3139) * ci: stop pinning lite validation legs to the 128gb runner The 128gb label matches a single runner, so every PR serialized six validate legs on it. Only the scheduled llama.cpp run needs that machine: it walks every hot model up to gpt-oss-120b (59 GiB), while PR and merge-queue runs are lite mode and test one 0.6 GiB model. sd.cpp never needed it at all -- its two test models peak at ~18 GB. Point sd.cpp at stx-halo unconditionally, and size the llama.cpp validate runners off the existing LITE_MODE env, surfaced as a build job output because the env context is unavailable in `strategy`.

* feat(models): add an explicit `chat` label Chat-ness was inferred in five inconsistent places: an allow-list in get_model_type_from_labels plus three copy-pasted "non-chat label" denylists. FastFlowLM has no chat marker at all -- 10 of its chat models report no labels and only worked via a silent LLM fallback. Make `chat` a first-class deployment label, stamped at every ingest boundary that cannot declare it, and collapse the five inference sites to one label test. Also removes the deprecated `Lite Collection` / `Ultra Collection` registry entries. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(models): derive the deployment label from the backend descriptor Each backend descriptor now declares a `default_classification`, and a single `ensure_deployment_label(labels, recipe)` stamps it at every ingest path when a model's own labels name no deployment mode. This replaces the recipe-blind `ensure_chat_label`, which labeled a bare sd-cpp or whispercpp user model as `chat`. - Add the missing `chat` label to Muse-Glimmer-30B-GGUF. - Check the registry invariant in CI (test/test_server_models_labels.py): every model declares exactly one modality, and it agrees with its recipe. - Classify FastFlowLM models by checkpoint name, since `flm list --json` reports input modalities rather than a deployment mode (ROCm/FastFlowLM#668). - Split get_model_type_from_labels() into find_deployment_mode() plus the LLM-fallback wrapper, so callers can tell "declares chat" from "declares nothing"; share one has_label() helper across the four ad-hoc idioms. - Document all nine deployment labels and the recipe-default fallback. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(models): drop the descriptor-outranks-labels guard The guard existed because `vision` / `reasoning` / `tool-calling` used to imply chat, so an sd-cpp model labeled `vision` or an onnxruntime model labeled `reasoning` typed as LLM and slipped past classifier-capability validation. With `chat` as the sole chat marker and the recipe's classification stamped at ingest, the only labels this could still override are ones a user typed by hand. The `classification` fixup stays, since /v1/classify is served only by onnxruntime; it now names that backend through its descriptor instead of relying on the removed branch to have returned first. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(models): treat `chat-transcription` as a capability, not a mode `chat-transcription` means a chat model takes audio in a chat turn and transcribes it as part of its answer, so it sits with `vision` and `tool-calling` rather than naming the LLM deployment mode — `chat` does that. A model carrying only capability labels now falls through to its recipe's default label. Also: warn at cache build for any model that reaches a client with no deployment label; restore the array/element type guards when reading `labels` off a `/v1/models` response; describe the FLM discovery workaround in terms of the actual `flm list --json` catalog; and correct the deployment-label docs to match `get_deployment_model_type()`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(models): declare each backend's supported deployment modes Each backend descriptor now lists every deployment mode it can serve, most default first, replacing `default_labels`, `default_classification` and the editorial `modality` string. A model's labels are reconciled against that list at ingest, so a label can no longer claim a mode its backend would reject at inference time. - `POST /pull` returns 400 and registers nothing when a definition names an unservable mode, via `labels` or the `embedding`/`reranking` parameters; collection imports reject the same definition before any component registers - Naming no mode stays valid: the recipe's default is stamped, so an LLM always carries `chat` and clients can test one label instead of inferring from absence - Deleted `get_deployment_model_type()`; label normalization runs on every ingest path, including the built-in cache build, so labels and ModelType cannot disagree - `/system-info` derives `modality` from the declared modes, and `bench` reads them directly instead of parsing the display string back into a ModelType, which also fixes llamacpp embedding and reranking benchmarks - `BackendModeContractTest` fails the build when a descriptor's declared modes disagree with the capability interfaces its server class implements Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(models): drop FastFlowLM's reranking claim FLM serves no /v1/rerank route (v0.9.46 registers only chat/completions, completions, embeddings, audio/transcriptions, models, version) and its catalog has no reranking model, so `IRerankingServer` made the descriptor advertise a mode nothing could satisfy. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(models): refuse an illegal set of mode labels instead of repairing it A label set either describes a model the backend can deploy or describes no model at all: a mode the recipe cannot serve, or two different modes, is now refused rather than normalized down to a winner. Two servable modes were the gap — llama-server is spawned with --embeddings for an embedding model only, so `["chat", "embeddings"]` advertised an endpoint the subprocess never had. /pull answers 400 and registers nothing; a stored entry that predates the rule is skipped at startup with an error naming it, leaving user_models.json untouched so it can be corrected by hand. Dropping the repair also removes the question of which mode wins, so labels and ModelType agree by construction.

* feat(api): manage per-model recipe options without loading Adds GET/POST/DELETE /v1/models/{id}/options so clients can save recipe options without loading the model and reset them to defaults. ctx_size now stores -1 as an explicit "size from available memory" choice, which a per-model entry could not express before. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): harden the model-options endpoints Addresses review findings on the per-model options surface: - Only a numeric ctx_size is exempt from the not-set filter, so a string can no longer be persisted and later throw where ctx_size is read as an integer (for example /api/show). - Saving refreshes just the edited model's cached options instead of invalidating the whole registry, keeping build_cache and its live cloud provider queries off the request path. - The read-modify-write of a model's saved entry happens under one lock, so concurrent clients editing different options cannot drop each other's key. - Reload detection moved into Router::options_require_reload, shared by load_model and the endpoint, so the reported reload_required cannot disagree with what a load does, and is read under a single lock. - Options whose default is null are type-checked as booleans rather than accepting anything. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): validate option values before saving them A second review pass found the previous fix incomplete: - Only "" and "auto" were filtered from ctx_size, so any other string (for example "8192") still reached recipe_options.json and made /api/show throw. Every non-number is now dropped. - POST checked option names and types but not values, so an unsupported backend or a negative ctx_size could be saved and left the model unloadable. Backend choices reuse RuntimeConfig::validate_backend_choice and ctx_size is range-checked. - A malformed ctx_size silently cleared the option instead of reporting the problem; only null and "" clear it now. - pinned is applied to a running process, which keeps its own pin state across loads, so the saved value could never have taken effect. - recipe_options.json is written under the lock, so concurrent writers can't land whole-file rewrites out of order. - The cache refresh reuses build_recipe_options instead of repeating its layering. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): apply pinned changes and keep the cache in step Third review pass: - Clearing pinned, or deleting the whole entry, left a live model pinned while the response reported it unpinned. Any change to pinned is now pushed to the running process, in both directions. - The cache update ran outside the lock that covered the merge, so two concurrent writers could leave the cache holding older options than the file. Merge and cache update now share one critical section. - recipe_options.json rewrites are ordered by their own mutex instead of holding the cache mutex across disk I/O, which every request thread contends on. - A failed write rolls the in-memory entry back rather than leaving it ahead of disk until the next restart. - Fractional values are rejected for whole-number options; the eviction engine ignores them silently. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): repair a save-failure deadlock and user-model pinning Fourth review pass: - The write-failure rollback called invalidate_models_cache() while already holding models_cache_mutex_, so a read-only or full cache dir turned a failed save into a server-wide hang rather than an error. - Router::set_model_pinned matches on the canonical model name, so pinning through a user model's bare public name threw after the save had already succeeded. The handler resolves the key up front. - A pin is pushed to the running process whenever the request covers it, not only when the saved value changes, since a prior request-scoped /load can leave the process out of step with what is saved. - Negative values are rejected for the eviction timeouts, which read them as "already expired" and tear the model down after every request. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): stop reporting successful saves as errors Fifth review pass: - Pinning checked liveness and set the pin under separate locks, so an eviction landing between them turned an already-committed save into a 5xx. Router::try_set_model_pinned does both under one lock and treats "not loaded" as an ordinary outcome. - Errors were reported against the requested name, which for an alias is deliberately absent from the registry, so any server-side failure came back as 404 "model not found". - ctx_size accepts "auto" as a clear, matching what every other option and /load already do with it. - The /load doc row for ctx_size no longer implies -1 restarts a running backend. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): validate option values through the config validator Sixth review pass: - Per-model options were validated more loosely than the same option names in global config, so a value POST /params rejects (steps: 0, cfg_scale: -3) was accepted here and then silently dropped by the backend that reads it. The endpoint now defers to RuntimeConfig::validate_backend, which is promoted to public alongside the validate_backend_choice and validate_bin_path helpers it sits with. - try_set_model_pinned no longer waits for slot clearance; it only flips a flag on a running process, and waiting could block a save that had already committed for the length of an exclusive job. - Dropped the now-unused update_model_options_in_cache wrapper and two comments that no longer described the code. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): stop rejecting merge_args, and cover the round-trip Seventh review pass: - Delegating to the config validator caught merge_args in its `*_args` rule, which demands a string, so no value of merge_args could be saved. Only backend-descriptor options have a global-config counterpart, so only those are delegated now. - Negative values are rejected for float options too, not just integers. - DELETE resets the pin whether or not one was saved; a request-scoped /load can pin a process without writing anything. - save_model_options rolls back a failed write like its sibling. - RecipeOptions::inherit reads merge_args defensively; a hand-edited non-boolean took down every read of the model. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): report the pin a load would actually use Eighth review pass: - effective.pinned reported the saved value, but Router::load_model keeps a live process's own pin instead, so the field contradicted both reality and its documented meaning. It now reports the live pin when the model is loaded. - DELETE no longer resets a pin that was never saved; a pin a /load request applied to the process is not part of the entry being erased. - Validation errors no longer name the config.json section for an endpoint whose keys are recipe option names. - The user-model test cleans up its recipe_options.json entry, and the round-trip test covers a second recipe so options with no global-config counterpart are exercised. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(test): stop deleting a checkpoint later tests depend on test_012v registers a user model against the endpoint test model's checkpoint to avoid a download, then deletes it during cleanup — which removes the shared file and made every later load of Tiny-Test-Model-GGUF fail with "llama-server failed to start". Caught by CI on the endpoint suites; reproduced locally as test_012v followed by test_013. Also from the ninth review pass: - DELETE no longer unpins a live model when the saved entry merely held `pinned: false`; only an active saved pin is this endpoint's to undo. - ctx_size rejects 0, which never auto-resolves and reaches FastFlowLM and vLLM verbatim as --ctx-len 0 / --max-model-len 0. - A failed options write is reported as a server error instead of "Failed to load model", which this endpoint never does. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): finish the pin overlay and guard the eviction settings Tenth review pass: - DELETE read a saved `pinned` with json::value(), which throws on a non-boolean, so a hand-edited entry made the endpoint that clears such entries return 500 instead. Read defensively, as RecipeOptions::inherit already does. - defaults.pinned kept the saved value while effective.pinned was overridden with the live pin, so the pair contradicted its documented meaning: erasing the saved entry does not unpin a running process. - The eviction settings now require a positive value. Zero evicts on the first sweep for the timeouts, and divides by zero for the weight factor, making the model the first eviction candidate rather than the last. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(api): drop pinned from the options endpoint pinned is live-process state: Router::load_model takes it from the running server rather than from saved options, so an endpoint that manages the saved layer has to chase live state to stay honest. Doing so produced a race, a TOCTOU, two wrong DELETE semantics and an inconsistent effective/defaults pair across seven review rounds. POST now rejects it with a pointer to /v1/load and /internal/pin, and it is omitted from effective and defaults. /v1/load, /internal/pin, and pinned in recipe_options.json are unaffected. Also revert the reload rule to main's: options_require_reload no longer excludes ctx_size, so /v1/load behaves exactly as it does on main and the helper is a pure extraction shared with would_reload. The pre-existing over-reload of auto-sized models is left for its own PR rather than being changed as a side effect of this one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(api): drop reload_required An independent review verified that the field reads true in the shipped default configuration: a model loaded with no saved options reports reload_required, and a second identical /v1/load really does restart the backend. The field is accurate — it faithfully reports main's reload rule — but that rule restarts auto-sized models on every load, so the field is true for the common case and tells a client nothing. Making it useful requires changing what /v1/load considers a meaningful option change, which is a pre-existing bug deliberately left out of this PR. Rather than ship a field that is true by default or change /load as a side effect, drop it. Router is now a pure extraction of resolve_effective_options, with the reload comparison byte-identical to main. Also: correct the comment describing how load_model picks up `pinned` (it uses the resolved options when no process is live, and only prefers the live process when one exists), note in the docs that `saved` can hold keys this endpoint refuses, unload before deleting a shared checkpoint in test_012v so Windows can unlink it, and put the new tests in the order unittest runs them. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(api): slim the options endpoint to its essentials Validation keeps the unknown-key, type, and ctx_size checks and drops the bridge into RuntimeConfig::validate_backend; the recipe_options.json writers keep the mutex-guarded read-modify-write and drop the rollback-on-write-failure machinery; the test suite trims to the four tests that guard the endpoint's contract and the ctx_size=-1 behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(api): report effective as a replayable load command GET /models/{id}/options embeds model_name in effective and defaults so either replays verbatim against /v1/load, and POST tolerates the body copy. The router's reload check now compares resolved rather than stored option sets, so a request that spells out a running model's own options is a no-op instead of a restart. Docs reworded per docs/dev/documentation.md.

The endpoint is new in this PR, so no released client sees the change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(api): show the load command replay in the options reference Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(api): absorb GUI3's /load/command into the options endpoint The response gains `args` (the to_cli_options rendering, with an auto ctx_size concretized) and `resolved_ctx_size`, and POST accepts `dry_run: true` to validate and resolve a change without persisting it. This covers everything GUI3_merging's /load/command endpoint serves, so the merge can delete it. to_cli_options takes GUI3's boolean-flag handling so the two branches no longer differ there. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(api): the load command is a curl of effective, not CLI args Drop the args field: a client presenting the load command renders a POST /v1/load of the effective body against its own base URL, which the server cannot know. resolved_ctx_size and dry_run stay for the context display and preview flows. to_cli_options reverts to main's version now that nothing on this branch calls it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(api): render the load command server-side The options response gains load_command: effective posted to /v1/load as a runnable curl command, built from the request's own Host header so it targets the base URL the client actually used.

The server now records that its size came from auto-tune, and a requested -1 against it compares equal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): rebuild saved options against the registry under the lock The registry layer was snapshotted before models_cache_mutex_ was taken, so a concurrent edit left the in-cache option set built from a stale one. Re-read it inside the lock through a _locked variant. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): let the caller supply the base URL and API key lemond only ever listens over plain HTTP, so a client reaching it through a TLS-terminating proxy is on https without the server knowing, and Host is the caller's own claim. Guessing either into a command meant to be run is worse than leaving $LEMONADE_BASE_URL for the client to substitute, and drops the caller's text out of the command entirely. A key-protected server now names $LEMONADE_API_KEY in the header its own /v1/load wants. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): answer 400 for numeric literals no int64 can hold json::parse raises out_of_range for a number too large for a double, and out_of_range is a sibling of parse_error rather than a subclass, so the body parser missed it and every JSON endpoint reported a 500. A literal above INT64_MAX also wrapped on its way to int64_t, landing 2^64-1 on ctx_size as -1, i.e. "size it automatically". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(api): cover the review findings on the options endpoint test_012t now replays an automatic ctx_size as well as an explicit one, test_012p rejects overflowing literals, and two new cases assert the command never repeats the caller's Host and does carry the header a key-protected server requires. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test: make the context-overflow tests set the context they need The four overflow tests inherited a ctx_size that test_012 persisted and never restored, which only overflowed because it happened to be small. Each now snapshots the model's saved options, pins a context its prompt cannot fit in, and restores the snapshot; test_012 restores its own.

…download model sizes (lemonade-sdk#3166) build_cache() unconditionally recomputes size from resolved_paths for every downloaded model. Backends that self-manage downloads (flm) only populate resolved_paths with a small metadata file (config.json), not the actual model weights, so the recomputed size rounds down to zero and overwrites the correct footprint value from discovery.

lemonade-sdk#2689) * feat: flag comment slop in a pre-commit rule, and run pre-commit in CI AGENTS.md asks for the non-obvious WHY and forbids the WHAT, but nothing enforces it, and AI-assisted PRs keep landing with one concept re-explained at four or five sites. This adds a check for that, per the shape proposed in discussions#2685. tools/check_comment_slop.py reads a DIFF, not whole files, so it never complains about comments a contributor did not write. It flags three things: one concept explained at 3+ sites, oversized blocks, and comment density. It FLAGS and never rewrites -- picking which of several duplicate explanations to keep needs judgement about where a confused reader lands, and an LLM in CI would be both a prompt-injection vector and unable to know the right seam. Duplicate detection keys on shared distinctive VOCABULARY rather than prose similarity, because the restatements are reworded rather than copy-pasted -- difflib misses them entirely. Two exemptions keep it off idiomatic code: a comment that points at the canonical explanation ("see X") is a cross-reference, not a repeat, and a test may restate the invariant under test. Three sites is the floor because a contract at the declaration plus the reason at the implementation is the idiomatic C++ pair, not slop. --assert-comments-only strips comments and blank lines from both revisions and asserts the code is byte-identical, so a change that CLAIMS to be a comment cleanup can prove it instead of asking a reviewer to take it on faith. CI runs pre-commit on CHANGED FILES ONLY. Repo-wide would fail on pre-existing black drift that is not the contributor's to fix. Validated RED/GREEN against real history: it flags the pre-cut lemonade-sdk#2588 diff that two maintainers objected to, passes the cleaned one, and independently caught a 3-site duplicate the author had missed by hand. 37 unit tests. It passes its own check. Co-Authored-By: GLM-5.2 <noreply@z.ai> Co-Authored-By: Kimi <noreply@moonshot.cn> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: make --assert-comments-only fail closed @fl0rianr found three ways the assertion could pass a change that was not comments-only. All three reproduced. Sweeping the rest of that surface turned up a fourth. - Python is compared as a TREE, not a token stream. Dropping INDENT and DEDENT made `bar()` inside an `if` and `bar()` after it compare equal, so moving a statement between scopes passed as a comment change. - a git command that fails no longer returns "" and read as "nothing changed". The first call is `git diff --name-only`: when that failed, the check found no files, no offenders, and reported success for a comparison that never ran. - C source is spliced before comments are stripped, because C removes comments in translation phase 3, AFTER a backslash-newline joins two lines in phase 2. Without it, DELETING the backslash from `// disabled \` promotes the line below it from dead code to live code -- a change entirely inside a comment -- and still compared equal. - a comment the toolchain obeys (`# type: ignore`, `# noqa`, an encoding cookie, `// NOLINT`) is compared in its own right. It survives into neither the tree nor the stripped code, so removing one changes behaviour invisibly. - an unparseable file raises instead of comparing equal to another unparseable file. CI: the base is the branch the change actually targets, so a PR onto a release branch is not diffed against main; and the slop heuristic is skipped in the merge queue, where HEAD carries the PRs ahead of this one and comments from several approved PRs would otherwise be pooled and fail one of them. The unit tests now run in CI. Co-Authored-By: GLM-5.2 <noreply@z.ai> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: a file mode change is not a comment change Found sweeping the file-SELECTION step, which nothing had examined -- every earlier round went straight to the parsers. `chmod +x` leaves every byte of content identical, so the code comparison saw nothing and the assertion certified the change as "comments and blank lines only". The mode is part of the tree: a PR labelled "comment cleanup" could make a file executable. Select from `git diff --raw -z` rather than `--name-only`, which carries the modes and keeps a path holding a space in one piece. Only a modified, same-mode source file can now be a comment edit; an added, deleted, renamed or retyped path is reported rather than reasoned about. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: compare Python as a tree AND a token stream Round-9 review (unboxed brief, GLM-5.2) found a comment the toolchain obeys that both layers missed, and two representations that each hide what the other sees. - `# type: int` is read by a type checker but is a node in neither the AST nor the token stream, and the directive check only knew `# type: ignore`. Any variable type comment could be rewritten under a comments-only claim. Also added the pyright, ruff, isort and flake8 directives. - the tree keeps a literal's VALUE and loses its written form, so `0x100000` and `1048576` dumped identically; the token stream keeps the form and loses the block structure, so a statement moved between scopes tokenised identically. Neither is sufficient alone, so require both: an edit now has to survive two representations that fail in different directions. - the encoding cookie is honoured only on the first two lines, as PEP 263 specifies. The reviewer also reported the cookie regex as over-matching prose. It does not: a line matching PEP 263's pattern IS a declaration, and CPython rejects `# the encoding: moved` with "SyntaxError: encoding problem: moved". Matching it is correct, so it stands. Co-Authored-By: GLM-5.2 <noreply@z.ai> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: skip string literals when tracking block comments, and widen the directive set Round-9 kimi review. Its BLOCKER -- a filename holding a space shattered by `.split()`, so `model.c manager.py` was read as two unchanged files and the real one never examined -- was already closed by the `git diff --raw -z` selection in the previous commit; the exploit is now a regression test. - `char s[] = "/*";` opened a phantom comment block, handing the next line of ordinary code to the slop detector as prose. Skip string and char literals when tracking it. - `# fmt: skip` and `# nosec` are obeyed by black and bandit; the directive set only knew `fmt: on|off`. - .pyi, .cxx, .hh and .hxx are source. A .pyi does not end with ".py", so the suffix test also had to learn it, or stubs would parse as C. Its report of a line-splicing bug on an odd number of trailing backslashes does not reproduce: C removes the backslash immediately before the newline, which is what str.replace does, and two backslashes leave one. It could not construct a false pass from it either. Co-Authored-By: Kimi <noreply@moonshot.cn> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: do not splice a backslash-newline inside a raw string I introduced this hole while closing the last one. Fixing the line continuation in a `//` comment, I spliced backslash-newlines across the whole file -- but C++ deletes a backslash-newline EXCEPT inside a raw string literal ([lex.phases]/2). The global pass therefore edited raw-string CONTENTS, so R"(hello \ world)" and R"(hello world)" compared equal, and a change to executable string content could ship as "comments only". Splice inside the scanner instead, which never steps into a raw string because _raw_string_at consumes each one whole. The line-continuation fix still holds, and an ordinary string still splices -- the exemption is raw strings alone.

No blocker; the raw-string fix from round 10 is confirmed closed. Four findings, all reproduced: - the CI job I added ran `git fetch --depth=0`, which is not a valid depth in any git version, so the pre-commit job failed on every trigger and the unit tests never ran in CI. checkout already fetches full history, so the flag was never needed. - in C, `??/` is a trigraph for backslash, so `// x ??/` continues the comment over the next line and buries live code. C source is de-trigraphed before splicing; a .h here is a C++ header, where trigraphs were removed in C++17, so it is left alone. - a file with invalid UTF-8 raised an uncaught UnicodeDecodeError instead of failing closed; git output is now decoded with errors="replace". - TEST_PATH_RE missed a root-level `test.cpp` (it required a following / or _), so a comment restating an invariant there could be flagged as slop. Co-Authored-By: Kimi <noreply@moonshot.cn> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: treat a shebang as a directive, and skip raw strings when tracking blocks Round-12 review, both families. No blocker; the eight prior false passes verified closed. Two findings, both reproduced. - glm: a shebang is a `#` comment, so a change to it was certified comments-only -- but the kernel obeys it when the file runs directly, and `#!/usr/bin/env python3 -O` silently disables every assert in the file. This tool is itself mode 755. Compare the first-line shebang in _directives_of, like the other toolchain-obeyed comments. - kimi (advisory): a raw string containing `/*` opened a phantom block comment in the slop detector, so the next line of code was read as prose. _block_open_after now consumes a raw string whole via _raw_string_at, as _code_of_cish already does. The security path was never affected -- it uses _code_of_cish, not this.

The tenth false pass, and it was in my own round-11 fix: I added `errors="replace"` to stop invalid UTF-8 crashing, and a code comment claiming a byte change would still show up. Both were wrong. `errors="replace"` maps EVERY invalid byte to one U+FFFD, so `\xff` and `\xfe` inside a string compare equal -- a code change certified as comments-only. `text=True` compounded it: universal newlines turned a raw `\r\n` inside a string (an HTTP template) into `\n`, hiding a CRLF change too. - read git output as bytes and decode with `surrogateescape` -- lossless and injective, so distinct invalid bytes stay distinct. - drop `text=True` so newlines are not translated; a raw CR inside a string is content. - `_code_of_cish` splits on `\n` and strips only spaces/tabs, not `\r`, so a CRLF change inside a string survives the final normalisation too (splitlines/strip erased it). A CRLF-saved file with an ordinary comment edit still passes -- both sides carry the same line-ending `\r`. Co-Authored-By: GLM-5.2 <noreply@z.ai> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: normalise line endings before scanning C, so a CRLF continuation splices Round-14 review (glm), and it was exposed by my own round-14 fix. Preserving raw CRLF bytes revealed that the `\`+newline splice only matched `\`+LF, not `\`+CRLF -- so on a CRLF `.c` file, deleting the `\` from a `// warn \` failed to splice and the revived code compared equal. `evil()` goes from dead to live, certified as comments-only. Fixed the class, not the instance: `_code_of_cish` normalises line endings to `\n` first, exactly as the compiler does in phase 1, so the existing splice handles CRLF and CR continuations alike. This also closes the CR-only case glm noted (an old-Mac file starting with `//` was read as one whole-file comment, hiding every change inside it). A line-ending change carries no code meaning -- a raw newline inside a "..." literal is ill-formed C -- so the round-14 attempt to preserve it was flagging an impossible input; normalising is both correct and what surfaced this blocker. Co-Authored-By: GLM-5.2 <noreply@z.ai> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: an inline block comment before code is a code line, not prose Round-14 review (kimi), job (a). `is_comment_line` matches a line prefix, so `/* note */ int evil = 1;` was classified as a comment and the code after the close was counted as prose -- a false positive in the slop detector. `collect` now scans each C line for code outside comments (`_scan_line`, extending the block-state tracker) and treats a line with any such code as code, however it begins. kimi's LOW (CRLF-sensitive blank stripping) was already closed by the line-ending normalisation in the previous commit. Both round-14 legs independently found the CRLF-continuation blocker, already fixed. Co-Authored-By: Kimi <noreply@moonshot.cn> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: close a block comment on a spliced */, and treat /* IWYU */ as a directive Round-15 review, both families, one blocker each (they diverged rather than converging). - glm: `*\<newline>/` splices to `*/` in phase 2, closing a block comment -- but the `*` and `/` are never adjacent for the scanner's check, so it stayed in the comment to EOF and swallowed the code after it as prose. Match the spliced form.

The change updates the v11.7.0 runtime integration. It adds backend capability contracts, model registration and option APIs, router lifecycle coordination, ROCm runtime handling, telemetry, benchmark automation, CI checks, packaging metadata, documentation, and focused tests.

Changes

v11.7.0 integration

Layer / File(s)	Summary
Backend contracts and model metadata `src/cpp/include/lemon/...`, `src/cpp/server/backends/...`, `src/cpp/resources/server_models.json`	Backend descriptors now separate deployment modes from capability labels. Model validation, label inference, and backend capability checks use shared registry APIs.
Model registration, options, and router lifecycle `src/cpp/server/model_manager.cpp`, `src/cpp/server/server.cpp`, `src/cpp/server/router.cpp`, `src/cpp/include/lemon/model_manager.h`, `src/cpp/include/lemon/router.h`	Model registration, saved recipe options, Hugging Face snapshot checks, prepared loads, runtime mutations, exclusive requests, reload recovery, pinning, and residency coordination are added.
Runtime services and telemetry `src/cpp/server/backends/backend_utils.cpp`, `src/cpp/server/runtime_config.cpp`, `src/cpp/server/streaming_proxy.cpp`, `src/cpp/server/server.cpp`	ROCm wheel and tarball handling, broadcast migration, directory validation, streaming cancellation, transcription formats, cache-token telemetry, routing counters, and structured telemetry are added.
CI, benchmarking, packaging, and documentation `.github/...`, `CMakeLists.txt`, `docs/...`, `contrib/...`, `data/...`	Benchmark workflows, gated-job checks, platform validation, release dispatch, package metadata, URI handling, API documentation, and configuration documentation are updated.
Validation coverage `test/...`, `tools/check_comment_slop.py`	Focused tests cover backend contracts, router lifecycle, model updates, configuration, telemetry, ROCm runtime handling, transcription, streaming cancellation, system information, cleanup, and comment detection.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 3acb1

This PR changes residency, model loading, backend selection, installation, and CI behavior, but the current version still risks shutdown hangs, leaked load state, unsafe local-import paths on Windows, incorrect backend or asset selection, and unreliable release gates. It is not ready to merge until the high-impact runtime and security issues are fixed or explicitly accepted.

Poem

A rabbit checks each mode and gate,
While routers guard a changing state.
ROCm paths and labels align,
Telemetry records shine.
Tests verify each release way—
Hop, v11.7.0, hooray!

Greptile Summary

This update reconciles the maintained fork with Lemonade v11.7.0 across server runtime behavior, backend support, configuration, API and CLI surfaces, benchmark automation, packaging, and documentation. Focused checks confirmed that benchmark archive extraction rejects TAR traversal entries and that benchmark resources and cache paths work independently of the launch directory. No blocking failure remains.

Confidence Score: 5/5

No blocking failure remains.

No accepted blocking findings remain after exercising archive extraction and benchmark path-resolution behavior.

T-Rex Logs

What T-Rex did

Ran a focused Python reproduction that imported extract_archive() and created a TAR containing both inside.txt and ../tar-outside.txt; extraction raised OutsideDestinationError for the traversal member, retained the safe in-destination file, and did not create the outside file.
Recorded the exact observed result: extract_archive_result=raised OutsideDestinationError for tar-outside.txt; inside_exists=True and inside_content present; outside_exists=False; the traversal did not escape the destination and the run exited with code 0.
Validated resource and cache resolution behavior by running a runtime probe that showed resource lookups anchor to the script location and environment-derived caches, independent of the launch directory.
Ran the benchmark validator from a non-repository temporary working directory with controlled HOME, XDG_CACHE_HOME, and LOCALAPPDATA values; the validator completed a dry-run successfully and demonstrated that cache paths are environment-driven.
Configured focused router lifecycle tests at revision 43b2b76; after installing the DRM header, the focused build started but did not finish within the time limit, and the exact focused router lifecycle test source was captured.

503-521: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

A prepared model load is never released on exception paths. Router::prepare_model_load returns state that must be either committed with load_prepared_model or released with abandon_prepared_model_load. Every call site releases it on selected early returns but no call site releases it when an intervening step throws, so failed loads leave router admission state behind. Introduce one RAII guard that abandons the preparation unless a commit flag is set, then apply it at each site.

src/cpp/server/server.cpp#L503-L521: guard the preparation so the not-downloaded throw at line 510 and the get_model_info/RecipeOptions calls at lines 512-514 release it.

src/cpp/server/server.cpp#L685-L695: guard the preparation so get_model_info (688) and the RecipeOptions constructor (689) release it before the catch at line 700.

Signal after request one enters the server.

Line 430 sets first_request_started before _non_streaming_chat_completion() issues requests.post. The watchdog can reap the old PID before request one reaches the server. Request two can then run after recovery, and this test passes without exercising concurrent admission during reload.

Add a server-side request-entry barrier for request one. Wait for that barrier before asserting the reload window and starting request two.

Inline comments:
In @.github/actions/check-gated-jobs/action.yml:
- Around line 19-34: Normalize the entire action.yml file to LF line endings,
preserving its YAML content and behavior.

In @.github/scripts/validate_backend_bench.py:
- Around line 292-301: Remove the unused binary_path parameter from run_bench
and remove the corresponding argument at its call site, while preserving the
existing binary configuration through lemonade config set and all other
arguments and behavior.
- Around line 397-406: Update find_previous_result to return the newest matching
run, runs[0], since it is called before the current run file is created;
preserve the existing filtering and None behavior when no prior run exists.
- Around line 114-125: Update extract_archive to pass filter="data" to tarfile
extraction, and require Python 3.11.4 or newer for this benchmark workflow so
the safety filter is available. Leave the existing ZIP extraction and executable
handling unchanged.
- Around line 84-96: Update download_file to use redirect handling that removes
Authorization from both the request headers and redirected request headers
whenever the redirect target changes host, while retaining authorization for
same-host GitHub requests. Preserve the existing download and HTTPError
behavior.

In @.github/workflows/benchmark-regression.yml:
- Around line 24-47: Set workflow-level permissions to contents: read, then
grant contents: write only to the report job that pushes benchmark-data. Remove
workflow-level HF_TOKEN and GH_TOKEN environment variables; scope HF_TOKEN to
model-download steps and GH_TOKEN to the release-download step, ensuring the
external FORK_EXE execution in bench inherits neither token.

In @.github/workflows/cpp_server_build_test_release.yml:
- Around line 1453-1463: Replace the inline pip and virtual-environment
bootstrap in the test-dependency installation step with the existing
.github/actions/setup-venv composite action, matching the invocation used by
test-deb-inference. First verify that setup-venv works inside the
build-environment:ubuntu24.04 container, then remove the duplicated apt, venv,
pip-upgrade, and requirements-install commands.

In @.github/workflows/docs_and_style.yml:
- Around line 146-159: Update the workflow’s base-reference logic to handle push
events separately: use github.event.before as the pre-commit base for
non-initial pushes, and guard initial pushes where no prior commit exists;
retain the existing merge-base logic for other events and avoid adding redundant
shell error settings.

In @.github/workflows/repo-manager.yml:
- Around line 41-74: Update both snap release candidate dispatch steps, “Trigger
snap release candidate build” and “Trigger lemonade-desktop snap release
candidate build,” to verify SNAP_RC_DISPATCH_TOKEN before invoking gh workflow
run and skip the dispatch with a clear message when it is absent. Make each step
non-blocking so token errors, dispatch failures, or sibling-repository outages
do not fail the job or prevent the later Run repo-manager step.

In @.github/workflows/validate_sdcpp.yml:
- Line 29: Remove the workflow-level GITHUB_TOKEN and scope it only to the
validate step that launches lemond, preserving the existing per-step GH_TOKEN
settings for GitHub API calls; add a brief comment documenting that the scoped
token is required to raise lemond’s API rate limit.

In `@contrib/debian/control`:
- Around line 2-5: Remove the Testsuite: autopkgtest-pkg-python field from the
Debian control metadata while preserving Standards-Version: 4.7.4 and the
remaining package fields unchanged.

In `@data/ai.lemonade_server.app.metainfo.xml`:
- Around line 47-49: Update both AppStream release entries in the releases
section from version 11.6.0 to 11.7.0, preserving their existing dates and XML
structure.

Apply the same fix in `@data/ai.lemonade_server.webapp.metainfo.xml` at line 48:
The web application metadata contains the same stale v11.6.0 release entry.

In `@docs/api/lemonade.md`:
- Line 229: Add a blank line between each affected API heading and its status
badge at the headings corresponding to lines 229, 290, 329, and 344, resolving
the markdownlint MD022 violations while leaving the surrounding documentation
unchanged.

In `@docs/embeddable/runtime.md`:
- Around line 170-174: Update the server-level key table in
docs/dev/getting-started.md to include models_dir, matching the documented
/internal/set keys and the existing models_dir description. Keep the broadcast
and extra_models_dir entries unchanged.

In `@docs/guide/configuration/llamacpp.md`:
- Around line 145-160: Update the ROCm install-method configuration handling to
validate LEMONADE_ROCM_INSTALL_METHOD before use, accepting only auto, wheel, or
tarball and rejecting or falling back for arbitrary values. Reuse the existing
rocm_install_method validation path so environment and config-file inputs
enforce the same behavior.

In `@src/cpp/cli/main.cpp`:
- Around line 643-646: Update the continuation condition in the model
recipe_options check to use four-space indentation instead of a tab, aligning it
with the surrounding condition without changing behavior.

In `@src/cpp/include/lemon/backends/backend_utils.h`:
- Around line 200-203: Add the standard <cstdint> include to backend_utils.h so
the uint64_t type used by read_dll_version is declared directly.

In `@src/cpp/include/lemon/model_manager.h`:
- Around line 336-338: Update the API comment for preview_saved_model_options to
state that it computes the result of applying an option update to the model
without persisting any changes.

In `@src/cpp/include/lemon/router.h`:
- Around line 405-413: Update PendingReloadState to provide default member
initializers for generation, phase, and residency_class. Initialize generation
and phase to their safe default values, and residency_class to the type’s
“unset” enumerator, matching the initialization conventions used by nearby
structs.
- Around line 381-383: Mark the try_begin_exclusive declaration with
[[nodiscard]], matching request_exclusive, so callers cannot discard its
ExclusiveAcquireResult admission verdict.
- Around line 435-440: Add a concise comment above the route-decision fields
`routing_decisions_total_`, `routing_switches_total_`, `route_fingerprint_lru_`,
and `route_last_target_` stating that all four are guarded by
`telemetry_mutex_`; leave the existing LRU behavior unchanged.

In `@src/cpp/server/backend_manager.cpp`:
- Around line 271-312: Update the method/version validation flow around
read_version_file so the requested ROCm installation method is checked first,
then the alternate tree is considered only as fallback; ensure a wheel request
does not return true from a matching tarball version when the tarball lacks
method.txt, while preserving the existing tarball preference behavior for auto
or tarball requests.
- Around line 328-337: Update the rocm_runtime_update_required repair logic in
install_backend() to remove both the tarball directory from
get_therock_install_dir() and the wheel runtime tree used by
install_therock_wheels() before calling install_therock_if_needed(). Ensure
install_rocm_runtime() cannot reuse an existing matching wheel installation
during this repair.

In `@src/cpp/server/backends/backend_utils.cpp`:
- Around line 1166-1182: Update cleanup_stale_version_dirs to compare each
directory’s version suffix rather than its full architecture-version name, so
directories for other architectures are preserved; adjust its call site to pass
version instead of the full directory name.
- Around line 1969-1977: Update stage_therock_hip_runtime to iterate through
every directory returned by get_therock_lib_paths, selecting the first directory
containing amdhip64_7.dll; only return false after all directories have been
checked without finding it.
- Around line 1867-1891: Update BackendUtils::therock_wheel_runtime_alive to
require every non-empty directory recorded in runtime_paths.txt to exist,
returning false immediately when any is missing and true only after all entries
are validated; preserve the existing handling for missing files and blank lines.

In `@src/cpp/server/backends/llamacpp/llamacpp_server.cpp`:
- Around line 515-525: Move the ROCm runtime staging call into the existing
enclosing block that already checks llamacpp_backend and computes rocm_arch,
reusing that variable without repeating either guard or get_rocm_arch(). Pass
fs::absolute(executable).parent_path() as the staging destination, matching the
CUDA branch and handling bare executable names correctly.

In `@src/cpp/server/backends/sdcpp/sdcpp_server.cpp`:
- Around line 189-196: Extract the shared backend-selection and alias-resolution
sequence from SDServer::effective_device and load into a private helper,
preserving the existing fallback behavior and resolved device conversion. Update
both effective_device and load to call the helper so plan_gpu_memory_admission
and the loaded device use identical backend selection.

In `@src/cpp/server/backends/thenoise/thenoise_server.cpp`:
- Around line 334-350: Update the handled-key set in the request passthrough
logic to include both “width” and “height”, so the loop after resolve_size()
cannot copy raw dimensions into body and override the resolved size. Preserve
passthrough behavior for other unmapped parameters.

In `@src/cpp/server/config_file.cpp`:
- Around line 35-51: Update parse_env_value() to convert the legacy no_broadcast
environment value into a boolean broadcast value using the inverse semantics
before merging and saving. In each configuration-loading path for distro
defaults, LEMONADE_DEFAULTS_PATH, and config.json, catch normalization errors
from normalize_legacy_keys() and apply the existing explicit fallback instead of
allowing startup to abort.

In `@src/cpp/server/model_manager.cpp`:
- Around line 2417-2438: Extract the repeated deployment-label validation
sequence into one shared helper in src/cpp/server/model_manager.cpp, covering
lines 2417-2438, 2491-2511, 2756-2770, and 5787-5800. The helper must call
illegal_deployment_labels, reject if needed, normalize_zerank_2_labels, validate
again, then call ensure_deployment_label; preserve each site’s existing refusal
behavior, including logging and skipping at the first three sites and throwing
at lines 5787-5800. Update all four blocks to use the helper.
- Around line 1285-1302: Update the extra-model directory checks to call
safe_is_directory for extra_models_dir_ before fs::status, allowing discovery to
proceed safely through Windows reparse points; retain fs::status only as
fallback error reporting. Apply the same ordering and handling in
validate_extra_models_dir_access.

In `@src/cpp/server/router.cpp`:
- Around line 2048-2062: Update the wait predicates in unload_model and
discard_model_runtime_state_locked to also exit when reclaim_shutdown_ is set,
allowing destructor-triggered shutdown to proceed without waiting for long-lived
PreparedModelLoad instances. Preserve the existing readiness conditions during
normal operation and ensure the shutdown path handles any remaining state safely
after the wait.

In `@src/cpp/server/runtime_config.cpp`:
- Around line 1014-1033: Remove the unreachable no_broadcast branch from
apply_changes and retain the broadcast branch, since
normalize_config_set_changes converts no_broadcast before application. Do not
alter the existing broadcast handling or previous-effective-value logic.

In `@src/cpp/server/server.cpp`:
- Around line 3011-3015: Remove the redundant models rejection condition and
exception from validate_and_canonicalize_collection_registration, leaving the
existing check in register_model_definition_internal as the sole owner of this
validation rule.
- Around line 3096-3121: Update validate_model_registration_name so local_import
also requires the model name to use the user. namespace, including when
has_definition is false. Preserve the existing early-return and local model
resolution flow in the surrounding registration logic.

In `@test/cpp/test_backend_utils_dll_version.cpp`:
- Around line 102-108: Update the missing-file setup in the test around
BackendUtils::read_dll_version to call the non-throwing fs::remove overload with
an std::error_code, matching the existing patterns in the nearby tests, while
preserving the v == 0 assertion.
- Around line 10-23: Update the test includes by removing the unused fstream
header and adding a direct vector header include; keep the existing BackendUtils
and platform-specific includes unchanged.

In `@test/cpp/test_config_discovery.cpp`:
- Around line 1-7: Add the <ctime> header to the includes in
test_config_discovery.cpp, placing it after <cstdio>, so the std::time calls are
properly declared.

In `@test/cpp/test_gfx_arch_gating.cpp`:
- Around line 39-49: Add a negative assertion for the lowercase family
placeholder string gfx110x alongside the existing uppercase placeholder cases in
the test covering is_concrete_gfx_arch, ensuring it is not classified as
concrete.

In `@test/cpp/test_gpu_memory_planner.cpp`:
- Line 149: Update the success summary in the GPU memory planner test so “All
GPU memory planner cases passed” is printed only when failures is zero; preserve
the existing failure reporting and exit-code behavior for failing runs.

In `@test/cpp/test_hf_update_check.cpp`:
- Around line 28-31: Update make_temp_test_dir in
test/cpp/test_hf_update_check.cpp at lines 28-31 to include a process or thread
identifier alongside the steady_clock tick. Apply the same identifier-based
naming change in the TempDirectory constructor in
test/cpp/test_runtime_config_directory_validation.cpp at lines 21-26; both
cleanup paths must remain unchanged.

In `@test/cpp/test_pip_download_parser.cpp`:
- Around line 58-71: Add a test case in the parse_pip_download_line tests for a
parenthesized unitless size, such as “Downloading package-1.0.whl (12)”. Assert
the line matches, the extracted filename is correct, and bytes equals the
numeric size using the default multiplier of 1, covering the unitless-size
branch.

In `@test/cpp/test_router_model_lifecycle.cpp`:
- Around line 32-39: Update BlockingBackendState::load to signal load_entered
only once, allowing repeated load() calls on shared state without throwing.
Widen the specified exception handlers in the affected async and blocked_loader
paths from std::runtime_error to std::exception so unexpected exceptions are
reported rather than terminating the process.

In `@test/cpp/test_routing_helper_reconcile.cpp`:
- Around line 141-178: Remove the unused resident_state helper and the unused
was_unloaded wrapper, or update the new test to call them instead of accessing
the underlying state directly. Keep the admission_state and unload-count
assertions behavior unchanged.
- Around line 514-548: Split the final combined check in
test_npu_memory_rejection_preserves_residency into three separate check calls:
one for the expected rejection reason, one verifying unload_count remains zero,
and one verifying after equals before. Preserve the existing condition values
and coverage while giving each assertion a specific failure description.

In `@test/cpp/test_streaming_proxy_cancel.cpp`:
- Around line 24-26: Update the format strings in the test output calls to use
newline escape sequences instead of literal backslash-n text, including the
PASS/FAIL messages and the other occurrences identified in the comment. Preserve
the existing output labels and formatting.

In `@test/server_cli2.py`:
- Around line 764-767: Update the cleanup in the test containing the broadcast
configuration command to capture the existing broadcast value before changing
it, then restore that observed value in the finally block instead of hardcoding
true; follow the existing capture-and-restore pattern used by
test_043_listen_all_via_runtime_config.

In `@test/server_endpoints.py`:
- Around line 8103-8108: Add a positive-control phase to
test_034_shared_repo_variant_resolves_after_refs_main_advances that mutates the
on-disk snapshot used for comparison, then run the update checker and assert
ENDPOINT_TEST_MODEL appears in its models result. Keep the existing
stale-provenance and unchanged re-pull assertions intact.

In `@test/server_eviction.py`:
- Around line 330-337: Update drive_idle_evaluation so it posts the
idle-evaluation request directly without invoking _evaluate_idle_now or the
assertion-bearing _simulate_vram_pressure path; retain the existing status
assertion for deterministic single-shot callers.

In `@test/server_pinning.py`:
- Around line 290-327: Extract the second watchdog cycle from
test_watchdog_reload_preserves_pin_state into a new test method named
test_watchdog_reload_preserves_dynamic_unpin. Make the new test independently
load the model with pinned=True and ctx_size=2048, unpin it, kill its backend,
reload it, and assert the replacement PID differs while the model remains
unpinned and retains ctx_size 2048.

In `@test/server_whisper.py`:
- Line 213: Update the test around _get_whisper_model to call
_load_whisper_model_or_fail() before using the model, ensuring focused execution
loads the model independently and validates the response-format contract.
- Around line 314-316: Update the error-response assertions in the relevant test
method to require result["error"]["type"] to equal "invalid_request_error",
while preserving the existing checks for the error field and response-format
message.

In `@test/test_server_models_labels.py`:
- Around line 62-64: Update the model-types declaration check around the
find_deployment_mode marker to validate that the function marker exists before
indexing the split result; when absent, fail through the test’s intended
assertion or failure message rather than raising IndexError, while preserving
the existing label extraction when the marker is present.
- Around line 99-107: Update the recipe label validation around
find_deployment_mode() to canonicalize both declared descriptor labels and
supported recipe labels through DEPLOYMENT_LABELS before comparing them.
Preserve valid synonym pairs such as embedding/embeddings and
classifier/classification, and report labels that cannot be mapped as unknown
descriptor modes separately from unservable canonical modes.

In `@test/utils/server_base.py`:
- Around line 177-195: Update unload_all_models to document its retry behavior,
including the attempts parameter and that it returns the final response when all
attempts produce statuses other than 200 or 404. Also pause before retrying any
unsuccessful status response, not only requests.RequestException failures, while
preserving immediate returns for 200 and 404 and re-raising the final request
exception.
- Around line 238-256: Update restore() to guard each cleanup network operation
and unload_model call so cleanup failures are caught and reported as warnings
without replacing the original test exception. Also add get_model_options and
model_recipe_options to the module’s __all__ alongside the existing model
helpers.

In `@tools/check_comment_slop.py`:
- Around line 382-385: Update both git diff invocations in the from_ref and
cached branches to include --no-ext-diff, --src-prefix=a/, --dst-prefix=b/, and
--unified=0, ensuring parsing always receives standard b/ added-line prefixes
regardless of repository configuration.

Outside diff comments:
In `@src/cpp/resources/backend_versions.json`:
- Around line 101-114: Update src/cpp/resources/backend_versions.json lines
101-114 so every listed architecture has a valid url_mapping entry, restoring
gfx908 and gfx90a mappings or removing them from architectures if unsupported.
Update install_therock in src/cpp/server/backends/backend_utils.cpp lines
1631-1645 to validate therock.url_mapping and fail with a clear error when a
listed architecture is unmapped, rather than falling back to a bare architecture
asset name.

In `@src/cpp/server/server.cpp`:
- Around line 503-521: Introduce an RAII guard for each
Router::prepare_model_load result, abandoning it unless load_prepared_model
commits successfully. Apply this to src/cpp/server/server.cpp:503-521, 685-695,
2641-2677, 6323-6351, and 7552-7557, covering all intervening throws and
confirming the already_loaded return releases preparation; at 819-836, move
collection/download checks before preparation or explicitly release on both
failures.

In `@test/server_watchdog_lifecycle.py`:
- Around line 425-455: Update the concurrent request test around run_request and
_non_streaming_chat_completion to signal first_request_started only after
request one has entered the server, using a server-side request-entry barrier.
Wait for that barrier before asserting the old PID was reaped and before
starting the second worker, so the test always exercises concurrent admission
during reload.

2419-2440: 📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift

Deployment-label validation sequence remains duplicated across four sites.

The same four-step sequence — call illegal_deployment_labels, refuse on failure, call normalize_zerank_2_labels, call illegal_deployment_labels again, then call ensure_deployment_label — is still repeated verbatim in four places. A future change applied to three copies and missed in the fourth would let one ingest path accept a label set another path refuses.

src/cpp/server/model_manager.cpp#L2497-L2513: user model ingest.

src/cpp/server/model_manager.cpp#L5789-L5802: get_model_info_unfiltered ingest.

Extract this into one shared helper that takes the refusal action (skip-with-log vs. throw) as a parameter, and call it from all four sites.

Inline comments:
In @.github/workflows/benchmark-regression.yml:
- Around line 527-528: Add a concise explanatory comment directly above the
permissions block containing contents: write, documenting why this elevated
permission is required; keep the existing permission value unchanged.

In `@src/cpp/server/backends/sdcpp/sdcpp_server.cpp`:
- Around line 189-195: Update SDServer::selected_backend to read the documented
“sdcpp_backend” option key instead of “sd-cpp_backend”, preserving the existing
fallback selection when the configured value is empty.

In `@test/cpp/test_config_discovery.cpp`:
- Line 222: Update the temporary-directory construction in the test setup to
include the current process identifier alongside the timestamp, ensuring
concurrent processes generate distinct paths before cleanup. Preserve the
existing naming prefix and time component.

In `@test/cpp/test_runtime_config_backend_validation.cpp`:
- Around line 3-7: Update the standard-library include block in
test_runtime_config_backend_validation.cpp to alphabetical order, placing cstdio
before cstdlib while leaving the other includes unchanged.

In `@test/test_comment_slop.py`:
- Around line 283-299: Update
test_range_diff_ignores_repository_diff_customization to isolate
environment-dependent reference resolution by clearing PRE_COMMIT_TO_REF (and
the related ref variable as established by the neighboring staged test) while
invoking slop.main(), then preserve the existing run assertion.

In `@test/test_validate_backend_bench.py`:
- Around line 136-145: In the test around VALIDATOR.main(), explicitly assert
that the install_fork_binary mock was called before accessing
install.call_args.args[2], so missing or untracked fork configuration produces a
clear assertion failure instead of an AttributeError. Preserve the existing

I addressed the outside-diff local-import finding in 3acb154. Both model_name and compatibility model ingress now reject forward- and backslash separators with HTTP 400 before Router or registry mutation; a normal user.* local import remains accepted. The public regression is in test/server_endpoints.py.
