These review corrections do not add a Soma environment variable or package + dependency, and 2.3.0 remains the unchanged rollback. Evaluator-only provenance + arguments and llama.cpp server flags are not runtime configuration additions. +- Replaced isolated latest-turn rewriting with a bounded full-task context. Transform + calls can receive the original role-preserving `system`, `developer`, `user`, + `assistant`, and `tool` messages; tool results and definitions; `tool_choice`; + `parallel_tool_calls`; response-format, modality, audio, and stop controls; the + immutable target tool calls; and a clearly separated failed assistant draft. + Model and sampling knobs, transport headers, endpoint credentials, and rejected + transform candidates remain excluded. System/developer instructions remain + authoritative below Soma's JSON and native-tool invariants. +- Replaced independent whole-field regeneration with one fixed joint-repair object + containing required nullable `reasoning` and `content` members. Soma classifies all + present fields before repair and requests values only for fields marked for repair, + allowing accepted reasoning to ground content and jointly generated reasoning to + precede jointly generated content. +- Isolated each classification envelope to the named draft field while retaining the + complete original request, controls, and immutable calls. Repair generation may + inspect fields it must replace, but integrity verification sees only retained draft + fields and the current candidate, preventing rejected sibling text from influencing + either decision. +- Specialized the existing repair schema per call so requested members are strings + and every other required member is null. Added local JSON syntax/top-level checks + and literal stop-sequence checks for both target and repaired output, a fixed + alternate focus for candidate three, and bounded privacy-safe candidate rejection + reasons. Exact nonblank punctuation, symbol, and empty-container outputs are not + rejected by an English-text heuristic. These corrections add no JSON-schema + dependency or temperature branch. +- Added explicit field outcomes. A rejected optional reasoning field is dropped when + usable content remains; a reasoning-only response without content or a native tool + call is not accepted as terminal success. Immutable native `tool_calls` survive + exhausted adjacent-prose repair, with only the unusable prose cleared. Returned + function calls must match supplied definitions, and multiple calls are rejected + when the request sets `parallel_tool_calls=false`. +- Defined the normal semantic route as primary reasoning-off classification, + candidate one, and integrity verification, followed—after a completed semantic + rejection—by up to two fresh secondary reasoning-on candidates from the original + context. Each secondary candidate is verified on secondary. Without a secondary, + recovery is limited to two primary candidates. Availability failover remains + request-local. Configuration now enforces primary `off` and secondary `on` so the + deployed route cannot silently differ from the route the evaluator qualifies. +- Added a reasoning-off verifier fallback for a reasoning-on verification result that + is truncated or structurally invalid. The identical candidate is checked once on + the same endpoint/model with thinking disabled; Soma regenerates only after a + completed verifier returns `rewrite`. Semantic repairs never receive a rejected + candidate or prior-failure prose; structural JSON recovery receives only a closed + reason. Any `finish_reason=length` result is treated as truncated even when its + partial text happens to be syntactically valid JSON. +- Added per-endpoint `TRANSFORM_MEDIA_MODE=placeholder|forward|reject` and + `TRANSFORM_SECONDARY_MEDIA_MODE`. Placeholder mode preserves typed part positions + and metadata while omitting binary payload; forward mode sends the original media + as native OpenAI multimodal parts; reject mode requires a compatible alternate + route or fails explicitly. A forward-capability rejection is never silently + downgraded to placeholder mode. Malformed scalar content parts are rejected before + the target call, and streamed assistant-audio data/transcripts are accumulated + rather than overwritten. Mixed text/tool plus audio turns preserve their audio; + audio-only target turns fail explicitly because the text repair contract cannot + inspect or repair that payload. +- Added `TRANSFORM_ALLOW_CLARIFICATION`, default `false`. Missing task inputs no + longer license arbitrary examples, placeholders, invented results, or generic + promises; a clarification is an acceptable repair only when the operator opts in. +- Added the opt-in `TARGET_RETRY_ON_UNREPAIRABLE`, default `false`. When the complete + target turn leaves neither usable content nor a native tool call, Soma may make + exactly one fresh target request with a fixed corrective system message inserted + after the leading system/developer block. It preserves the original conversation + and tool contract and never includes rejected target or transform output. Optional + failed reasoning does not trigger this retry when content remains usable. +- Added the opt-in `TARGET_LOOP_BACK_ON_VERIFIED_REPAIR`, default `false`. When an + integrity-verified repair rewrites the target's refusal reasoning, Soma may make + exactly one additional target request consisting of the original conversation plus + a single assistant message carrying only that verified repaired reasoning in a + `reasoning_content` field, so the target re-ingests the relaxed context and + produces the task output itself. The second response is processed under the same + bounded rules and never loops again; genuine refusals never loop because they + classify as `pass`. Loop-back and `TARGET_RETRY_ON_UNREPAIRABLE` remain mutually + exclusive per request under the shared two-target-call ceiling and aggregate + transform deadline. Backends that reject `reasoning_content` in input messages + fail explicitly. +- Raised the defaults to `TRANSFORM_CONTEXT_MAX_CHARS=131072`, + `TRANSFORM_FIELD_MAX_CHARS=32768`, `TRANSFORM_DECISION_MAX_TOKENS=1536`, + `TRANSFORM_REWRITE_MAX_TOKENS=16384`, and + `TRANSFORM_TOTAL_TIMEOUT=1200`. Semantic context is never silently truncated; the + configured context limit is capped at 4000000 characters and the field limit must + not exceed it. The limit is enforced after each phase removes discarded draft + fields, so oversized optional reasoning cannot block an otherwise bounded content + repair. +- Removed `TRANSFORM_CONFIRM_REWRITES`. Any presence of the obsolete variable now + fails configuration validation so a stale profile cannot appear to enable behavior + that no longer exists. +- Set hard ceilings of two target calls, 20 transform calls per target response, and + 40 transform calls for one client request. Default configuration still makes one + target call because target retry is disabled. Fail-open no longer permits a + reasoning-only or otherwise empty terminal response. +- Expanded privacy-safe diagnostics, offline coverage, and live qualification around + full context, media routes, joint field policy, semantic candidate routing, + verifier fallback, and optional target retry. The frozen evaluator now covers 240 + classification cases, 80 balanced joint message repairs, all three media modes, + staged primary-off/secondary-on routing, retained/forbidden facts, schema-off and + repeat sentinels, and reproducibility. Live target smoke remains explicitly opt-in. + Soma 2.4.0 ships unqualified until the exact transform profile passes every + automated gate; the report retains hash-bound evidence for all 80 repairs, and the + evaluator never downloads, loads, switches, starts, stops, or restarts a model. + Error responses after dispatch now carry the same privacy-safe counters as success + responses, target elapsed time includes malformed target responses, and exact + qualification records a dedicated secondary reasoning-budget value. +- The live evaluator can record llama.cpp's unrestricted reasoning-budget sentinel + as `--reasoning-budget -1` for an honest exploratory run. This never satisfies the + positive bounded-budget qualification gate; it only prevents current deployments + from being mislabeled as budget `0` or `512` while collecting repair evidence. +- Defined the first qualifying local route as temperature zero with a bounded + llama.cpp `--reasoning-budget 512`, recorded by the evaluator with the matching + `--reasoning-budget 512`. Temperature zero removes intentional sampling variance + from repeat gates but is not a guarantee of byte-identical output; other + temperatures and budgets remain separate profiles that need their own reports. +- Made the automated gates the sole qualification stage. A complete pass records + `qualified: true` and `qualification_status: qualified`; a failed gate records an + unqualified profile. Hash-bound retained outputs remain audit evidence and do not + form a separate approval stage. +- Added an explicit provider-managed evaluator profile for hosted-model experiments. + It records a retained, hash-bound public model metadata record and non-secret + endpoint/model identities, rejects fabricated local GGUF or reasoning-budget + provenance, and is always marked exploratory rather than qualified. Target smoke + now requires the exact requested `OK` token instead of accepting arbitrary + non-empty content. +- Added an explicitly unqualified hybrid evaluator profile for a local GGUF primary + and provider-managed secondary. It retains both provenance records without + pretending the hosted reasoning budget is known. Target-smoke requests now allow + 128 output tokens while still requiring the response to be exactly `OK`. +- Kept the unrestricted-budget Qwen3.5-9B Q6_K report unqualified until a complete + replacement run exists. In-place evaluator stabilization changes its source/corpus + evidence identity, so the evaluator atomically installs a fresh temperature-zero, + 512-token report before the obsolete unrestricted artifact is removed; the old JSON + is never edited or promoted. + +## 2.3.0 + +- Replaced exact excerpt extraction, Unicode-equivalence recovery, unique-anchor + resolution, bounded fragment generation, masked retries, and local splicing with a + decision-only `pass | rewrite` classifier and complete-field regeneration. The + simpler contract removes the highest-fragility requirements for small transform + models while giving every model enough user context to produce a substantive + answer rather than a generic bridge. +- Added mandatory post-rewrite classification. Every locally valid candidate must + independently classify as `pass`; a residual or paraphrased refusal, + nonresponsive bridge, malformed verification result, or verification failure + rejects the candidate. +- Added one bounded fresh-regeneration path from the pristine source after a + received-output or post-check failure. A configured secondary performs the second + candidate when available; otherwise primary is reused. Rejected candidate text is + never fed back to either model, and the final candidate is verified exactly once. +- Added `TRANSFORM_REWRITE_MAX_TOKENS`, defaulting to 4096 with a valid range of + 256–16384. Complete replacements are bounded after decoding to + `min(16,384, max(4,096, 2 * source characters))`; the rewrite schema deliberately + omits a dynamic `maxLength` for structured-output compatibility. +- Added explicit 16,384-character rewrite-input limits without semantic truncation. + Missing textual user context and oversized source/user inputs are deterministic, + field-scoped failures. Mixed-media turns carry an `unseen_media` flag; pure + non-text turns cannot be regenerated. +- Limited transform context to the complete field, latest textual user turn, + `tool_turn`, `unseen_media`, the deterministic output bound, and an optional closed + retry reason. Earlier messages, system instructions, processed reasoning, tools and + arguments, headers, credentials, and rejected candidates remain excluded. +- Raised the per-completion transform-call ceiling from eight to twelve to cover two + complete `(regeneration + post-check)` candidate paths for each reasoning/content + field while retaining at most two classification votes, the aggregate transform + deadline, one target call, and request-local backend stickiness. +- Removed the DSML parser, shim, counters, diagnostics, and documentation. Soma now + preserves native OpenAI `tool_calls` only; proprietary text-to-tool conversion is + owned by the target's OpenAI-compatible gateway. Native calls now require a + nonblank unique ID and `type: function`, preventing stream/non-stream envelope + drift and uncorrelatable tool results. +- Tightened the post-`[DONE]` SSE extension to at most one object with `choices: []`, + no keys outside `choices`, `cost`, and `usage`, and at least one non-null metadata + value. The postlude may end at EOF or one closing `[DONE]`; all later data is + rejected, and upstream error objects retain the redacted stream-error path. + Normalized outbound SSE emits one accepted `cost`/`usage` metadata event instead + of repeating one-shot cost data on every delta. +- Added `X-Soma-Postcheck-Rejections` and `classify`, `rewrite`, and `postcheck` + phase diagnostics with candidate/backend/reasoning/purpose metadata. Removed + rewrite-mode and DSML diagnostics while retaining strict privacy-safe logging, + field decisions, repair counts, rejected-rewrite counts, and fail-open visibility. +- Reworked live qualification around the exact imported 2.3.0 runtime, decision-only + classification, complete-field replacements, and verified final output. Local + reports belong under excluded `qualification-local/`; Soma never downloads, + starts, stops, switches, or otherwise manages a model. +- Distinguished automated-gate success from final qualification: reports remain + `pending_manual_review` until the 40 retained source/replacement pairs receive + independent semantic review. Exact-pair runs with a configured secondary inject + one labeled primary-unavailable event and require real secondary classification, + regeneration, and post-check calls; reports include per-backend phase counts. +- Made live provenance fail closed if either the imported Soma source or evaluator + changes during a run, preventing a report from hashing different code than it + actually exercised. + +## 2.2.7 + +- Fixed the 2.2.6 streaming regression that rejected OpenAI-compatible gateway + usage or billing postludes emitted after an upstream `[DONE]`. Empty-choice + metadata is now preserved, including an optional final `[DONE]`, while premature + delimiters, malformed postludes, and any post-delimiter choice data remain invalid. +- Added explicit `off`, `on`, and `default` transform reasoning modes. `off` + preserves the 2.2.6 request shape, `on` uses llama.cpp's + `chat_template_kwargs.enable_thinking=true`, and `default` leaves reasoning + controls to the server. The setting applies consistently to classification and + rewriting. +- Added one optional, fully explicit secondary transform endpoint/model profile. It + may point to the primary server with a different reasoning mode or to an + independently operated server/model, but it shares Soma's prompt, temperature, + JSON contract, validation, and fixed generation bounds. +- Kept recovery bounded to the existing second attempt. The secondary can replace a + failed primary attempt after connection/timeouts, HTTP 408/429/5xx, invalid outer + completions, or locally rejected classification/rewrite output. Configuration + errors and other non-transient 4xx responses remain visible. +- Added optional secondary confirmation for valid primary `rewrite` classifications. + A secondary `pass` conservatively preserves the field; two valid `rewrite` + decisions retain the primary anchor. Confirmation is disabled by default and does + not add a third classification attempt. +- Added request-local failover: after a transient primary availability failure, only + the remaining transform phases in that Soma request begin on secondary. The next + client request starts on primary, so Soma retains no cross-request circuit-breaker + or harness/session state. +- Added a 600-second aggregate transform budget, starting after the single target + call, so retries and multi-field processing cannot multiply the per-call timeout + without bound. The one-target-call invariant and eight-transform-call ceiling are + unchanged. +- Extended safe diagnostics with backend, reasoning mode, call purpose, secondary + call/failover/disagreement counts, and transform-deadline failures without logging + prompts, generated text, anchors, credentials, or raw upstream request IDs. +- Extended live qualification to exercise explicit reasoning modes and composed + primary/secondary behavior without managing models. Deployment guidance requires + a secondary to qualify alone and the exact pair to qualify before an operator + enables confirmation; the evaluator does not change runtime configuration. +- An exploratory test of the operator-selected Qwen3.5-9B Q6_K with reasoning enabled + at temperature 0 removed the two reasoning-off false rewrites but regressed overall + refusal recall from 99% to 96%, introduced four invalid/missed partial-refusal + anchors and ten repeat failures, and remained unqualified. Targeted 64/128/256-token + reasoning budgets were non-monotonic, so Soma adds no model-specific + reasoning-budget knob. + +## 2.2.6 + +- Preserved the 2.2.5 one-target-call flow, phase prompts, bounded transform call + counts, anchored/masked rewrite behavior, DSML normalization, `FAIL_OPEN` policy, + endpoints, and runtime environment variables while simplifying the implementation. +- Removed unused transform compatibility helpers, prefiltered protected + `ENABLE_REASONING` fields before overlay, reduced target-response mutation to one + working deep copy, removed custom HTTP pool sizing, and consolidated rewrite + contract validation under its owning parser/semantic validator. +- Made client flag validation exact: `stream` and `parallel_tool_calls` must be + booleans, while `n` is null or integer `1` and no longer accepts a boolean. +- Added target assistant-message validation before DSML or transform calls, including + role/content types, one non-empty reasoning alias, native tool-call shape, + non-blank function names, JSON-string arguments, and unusable empty turns. Unknown + valid target metadata remains preserved. +- Limited latest-user transform context to text: plain strings and the textual parts + of multimodal arrays are joined, while image, audio, file, base64, tool, and other + non-text metadata is omitted. +- Required refusal anchors to contain at least one letter or number and begin and end + on source boundaries; rewrites must likewise contain a letter or number. + Context-copy checks now ignore only splice-edge whitespace, closing the + copied-neighbor bypass without changing the local exact-splice behavior. +- Replaced generic streamed-response merging with explicit OpenAI delta assembly. + Text and every tool-call fragment append in arrival order, including identical + fragments; stable metadata is checked explicitly and unknown metadata uses + last-value semantics. Cumulative snapshot providers are explicitly unsupported. +- Require a terminal non-null SSE `finish_reason`; reject `[DONE]` or EOF before it, + meaningful deltas after it, malformed event JSON, and non-finite values. Normalized + outbound SSE remains unchanged. +- Reject non-finite configuration numbers, malformed endpoint ports, endpoint + userinfo/query/fragment components, duplicate or framing-sensitive configured + headers, duplicate transform-contract object members, and non-finite JSON across + client, target, transform, SSE, and DSML boundaries. Wire JSON now uses a strict, + surrogate-safe encoder. +- Tightened HTTP request framing to reject simultaneous `Content-Length` and + `Transfer-Encoding`, non-sole chunked encodings, negative chunks, and unterminated + chunk framing. No in-process body-size or buffering cap was added; those limits + remain the responsibility of a trusted front proxy. +- Preserved leading and trailing whitespace for DSML `string=true` arguments while + continuing to trim non-string JSON arguments. Sanitized upstream request IDs before + reflection and prevented upstream headers from colliding with Soma diagnostics. +- Reduced client-facing detail for streamed target/internal failures while retaining + server-side diagnostics, and removed query strings and upstream error text from + routine proxy-error logs. +- Added an opt-in standard-library live qualification evaluator with 200 reviewed + classifier fixtures, 40 category-balanced rewrite fixtures, schema-off sentinels, + deterministic parallel/repeat gates, reproducibility metadata, synthetic rewrite + output for human audit, and an optional 50-case one-shot target gate. Its reviewed + anchors must cover the curated refusal core, its JSON/channel selection mirrors the + runtime, and reports fingerprint the exact prompt/source/configuration snapshot. + It never downloads, switches, loads, or restarts a model. +- Recorded the tested aggressive Qwen3.5-9B Q8_0 deployment as unqualified after + false-positive and rewrite-stability failures. The official Qwen3.5-9B Q8_0 remains + a candidate that must independently pass the same gate; Soma performs no model + management. +- Recorded the operator-selected DavidAU Qwen3.5-9B Q6_K artifact as reproducibly + unqualified at temperature 0, seed 1, the temperature sampler, and one server slot; + preserved its exact machine-readable qualification report with the release. A + per-request temperature-0.7 comparison was also preserved and was substantially + worse, with 43 false rewrites and 93% refusal recall. Temperature 0 remains the + better tested setting, but neither configuration qualifies. +- Added two copyable deployment profiles using only existing variables, with one Soma + process and distinct listener port per harness. Documented isolated profile startup, + the trusted-local/reverse-proxy boundary, front-proxy resource limits, and the + non-loopback warning. No runtime harness branching was introduced. + +## 2.2.5 + +- Fixed the observed 2.2.4 semantic-echo failure in which classification recovered to a valid literal anchor, but both rewrite attempts returned complete, schema-valid, `finish_reason=stop` JSON whose replacement was unchanged from that anchor; this was not a JSON-mode, truncation, or token-budget failure. +- Split the built-in classification and rewrite guidance so classification remains observational while the editor is explicitly permitted to produce a bounded non-refusal fragment without independently solving the user request. +- Strengthened classification recovery guidance so a corrected excerpt must remain a unique, exact, syntactically replaceable refusal clause containing the withholding decision rather than merely any literal source text. +- Kept the initial rewrite and ordinary repairs anchored, but masked `refusal_anchor` from the sole second attempt after an `unchanged` or `anchor_retained` result. The masked request carries only the field, bounded contexts, `anchor_omitted: true`, and the closed failure reason; the exact anchor and offsets remain local for validation and splicing. +- Added field-specific masked guidance that relies on the local splice to preserve both contexts and forbids copying, paraphrasing, summarizing, or otherwise reproducing them in the replacement. +- Made the field fallback instruction unconditional on every `masked_anchor` retry after a live Qwen run ignored a buried conditional fallback and copied immutable context. The final system instruction, appended after the masked contract, directs the transform to return exactly `{"replacement":"Proceed with the requested work."}` for reasoning or `{"replacement":"I'll proceed with the requested task."}` for content. This gives the semantic retry a fixed, unambiguous target while preserving normal server-output parsing, local validation, candidate-exhaustion, and `FAIL_OPEN` behavior; the shared schema and validator still accept any otherwise valid replacement fragment. +- Added privacy-safe `rewrite_mode=anchored|masked_anchor` diagnostics without logging the anchor, replacement, target text, user context, or rejected output; non-rewrite phases use `none`. +- Preserved the 64-character anchor cap, 512-character contexts, 256-character replacement cap, 384-token rewrite budget, two rewrite attempts, one target call, and eight-transform-call ceiling. Rewriting still receives no latest user turn, unbounded target field, or processed reasoning, and still has no complete-field fallback. +- Preserved `FAIL_OPEN` behavior: strict mode returns the exhausted transform error, while fail-open mode preserves only the affected field, marks it `failed_open`, and continues. + +## 2.2.4 + +- Fixed the observed 2.2.3 failure in which classification JSON was valid, an initial complete-field rewrite retained the refusal, and its repair exhausted the token budget before closing its JSON object; JSON mode was enabled but could not guarantee completion of the unbounded complete-field edit. +- Replaced complete-field refusal rewriting with a deterministic local splice: classification must resolve a unique source anchor of at most 64 decoded characters, and the transform receives only that anchor plus at most 512 source characters on each side. +- Require the rewrite model to return only an anchor replacement of at most 256 decoded characters, with the fixed cap expressed in the llama.cpp-compatible JSON schema, repeated in the prompt, and enforced authoritatively in Python. +- Reject and repair complete-field candidates that repeat immutable context across a splice boundary or embed a substantial boundary segment inside wrapper text. +- Bound rewrite generation to 384 tokens and preserve the original prefix and suffix exactly; only the bounded source window is sent, never the latest user turn or processed reasoning, and there is no complete-field rewrite fallback. +- Apply one failure-specific repair to any received but unusable rewrite candidate, without echoing candidate text or exception details into the retry. +- Make exhausted rewrite candidates consistently honor `FAIL_OPEN`: strict mode returns 502 with the specific transform failure, while fail-open mode preserves only the affected field and marks it `failed_open`. +- Retained all endpoints, environment variables, response headers, client formats, the one-target-call invariant, and the eight-transform-call maximum. +- Documented that fixed small `maxLength` constraints work with the tested llama.cpp structured-output path, while previously considered large dynamic limits did not; because the schema is not model-visible, prompts also state each cap and local validation remains authoritative. + +## 2.2.3 + +- Reduced classification excerpts from 128 to 64 decoded characters and directed the classifier to choose a compact, normally 2–8-word refusal anchor. +- Required exact contiguous provenance after JSON decoding, preserving case, Unicode punctuation, CRLF and other line endings, tabs, repeated spaces, and non-breaking spaces. +- Resolve only unique CRLF, no-break-space, or curly-quote normalization matches back to the exact original source slice with a streaming, memory-bounded matcher before rewriting; ambiguous matches, lone-CR changes, case changes, omissions, and general whitespace changes remain invalid. +- Clarified that llama.cpp JSON grammar constrains structure and string length but cannot enforce the dynamic rule that an excerpt occurs in the supplied source text; Soma continues to enforce that relationship locally. +- Gave the existing single classification recovery call failure-specific guidance using a closed failure reason, without echoing rejected transform output into the retry. +- Added privacy-safe diagnostic failure categories for invalid JSON or contract shape, pass-with-excerpt, empty excerpt, excessive length, and nonliteral excerpts; source text, excerpts, and transform output remain excluded from logs. +- Preserved the public `invalid_transform_output` error code, JSON-mode default and behavior when disabled, endpoints, environment variables, response headers, field-scoped `FAIL_OPEN` semantics, 768-token classification budget, and existing target and transform call bounds. + +## 2.2.2 + +- Simplified classification to the strict `pass | rewrite` contract and removed the `safety` outcome. +- Route every refusal or withholding decision, including decisions formerly classified as safety boundaries, through the existing context-isolated rewrite stage. +- Continue using the latest user turn only for classification; rewriting still receives only the target field, refusal excerpt, and optional processed reasoning. +- Removed the safety-preserved counter, response header, and field-decision value from current diagnostics. +- Updated transform call bounds: `pass` stops field processing, while every refusal or withholding classification invokes the bounded rewrite path. + +## 2.2.1 + +- Recover once from empty, truncated, malformed, or contract-invalid classification output before applying the configured field-scoped `FAIL_OPEN` policy. +- Preserve transform completion metadata and report incomplete classification generation as `transform_output_truncated` instead of an undifferentiated invalid-JSON error. +- Bound classification output to 768 tokens and require `rewrite` and `safety` excerpts to be literal, nonempty substrings no longer than 128 characters; `pass` requires an empty excerpt. +- Added `X-Soma-Classification-Retries` and safe classification-recovery diagnostics without logging transform output or request content. +- Treat decoded empty, missing, non-string, or structurally invalid rewrite replacements as `rewrite_rejected` while retaining operational handling for malformed JSON. +- Require literal equality for reasoning/content duplicate routing so case- or whitespace-normalized variants cannot replace the original field. +- Reject short and medium processed-reasoning copies in rewritten content using normalized equality, bidirectional containment, and bounded similarity checks. +- Documented classification and rewrite call bounds and clarified that JSON mode is enabled by default, requires a process restart after environment changes, and can be verified with `--check-config`, startup diagnostics, or `/health`. + +## 2.2.0 + +- Split transform processing into contextual classification and context-isolated rewriting. +- Restored the exact latest user turn only for classification; user context never reaches rewriting. +- Added `pass`, `rewrite`, and `safety` classification outcomes. +- Preserve legitimate safety boundaries instead of treating every refusal as editable. +- Require an exact refusal excerpt for rewrite decisions. +- Added one bounded rewrite-only repair when an edit is unchanged or retains the classified excerpt. +- Removed strict reasoning compression and lexical-similarity floors; retained catastrophic growth and reasoning-copy protections. +- Process duplicate final text as content and duplicate tool-turn text as reasoning. +- Added detected-refusal, safety-preserved, and rewrite-repair diagnostics. +- Retained stateless operation, one target call, native tool-call fidelity, DSML normalization, buffered SSE, and field-scoped fail-open behavior. + +## 2.1.2 + +- Rebalanced refusal handling with more sensitive classification and conservative edits. +- Added independent field processing and `rewrite_rejected` diagnostics. + +## 2.1.1 + +- Ignored unnecessary replacement text when `refusal:false`. +- Simplified llama.cpp JSON grammar to avoid nested `maxLength` failures. + +## 2.1.0 + +- Removed user context from transforms, separated reasoning/content guidance, added structured JSON, rewrite bounds, and duplicate handling. diff --git a/README.md b/README.md new file mode 100644 index 0000000..b66b71b --- /dev/null +++ b/README.md @@ -0,0 +1,740 @@ +# Soma 2.4.0 + +Soma is a stateless OpenAI-compatible Chat Completions proxy. It buffers and +validates a target assistant turn, identifies operative refusal or withholding, and +uses a separately configured transform model to produce a context-grounded repair. +Native OpenAI `tool_calls` and valid response metadata remain target-owned and +immutable. + +Soma 2.4.0 addresses the central weakness of 2.3.0: a transform cannot accurately +repair references such as “the supplied text,” “both functions,” or “the preceding +result” when it receives only the latest user string and failed assistant field. +Version 2.4 supplies bounded full task context, repairs reasoning and content +together when necessary, distinguishes optional reasoning from the usable answer, +and uses an integrity verifier that can reject invented or context-breaking output. + +Soma 2.4.0 is not pre-qualified. JSON grammar guarantees neither correct semantic +decisions nor grounded repairs. The exact model artifact, server build, endpoint +pair, reasoning modes, media modes, prompt, budgets, and temperature must pass the +live automated qualification gates before deployment. Reports retain hash-bound +outputs for audit and reproduction, but inspection is not a separate qualification +stage. + +The pre-release 2.4.0 tree was stabilized in place rather than assigning a new +version to review corrections made before qualification. The rollback remains the +unchanged 2.3.0 directory. This stabilization adds no Soma environment variable and +no package dependency; existing 2.4.0 profiles retain the same runtime contract. +Evaluator CLI provenance such as `--reasoning-budget` and the corresponding +llama.cpp server option are not Soma environment settings. + +The current Qwen3.5-9B Q6_K route is unqualified. Its exploratory temperature-zero +report used unrestricted secondary reasoning and failed automated gates. That report +is diagnostic evidence only: it cannot be promoted or reinterpreted after evaluator +stabilization. A fresh bounded-budget report must replace it as the current +qualification record. + +Soma never downloads, loads, switches, starts, stops, or restarts a model. It does +not execute tools, maintain conversation state, authenticate clients, or provide +tenant isolation. + +## Request flow + +With the full primary-off/secondary-on staged profile, the normal path is: + +```text +client request + -> target model + -> buffer and validate one complete assistant turn + -> build one bounded, role-preserving task context + -> classify every present reasoning/content field on primary, reasoning off, + with the other draft text fields removed from that classification envelope + -> apply field policy and, if necessary, request one joint repair object + candidate 1: primary/off -> primary/off integrity verification + candidate 2: secondary/on -> secondary/on integrity verification + candidate 3: secondary/on -> secondary/on integrity verification + -> if an on-mode verifier truncates or returns invalid JSON: + verify the identical candidate once on the same endpoint/model, reasoning off + -> retain usable verified fields and immutable native tool calls + -> if the turn is still unusable and target retry is enabled: + call the target once more with a fixed corrective system instruction + and process that fresh response under the same bounded rules + -> if a verified repair rewrote reasoning and loop-back is enabled: + call the target once more with only that verified reasoning appended + and process that fresh response under the same bounded rules + -> deduplicate exact reasoning/content copies + -> return JSON or normalized SSE +``` + +Candidate two is generated only after a completed integrity verifier semantically +rejects candidate one, or after an eligible route failure. Candidate three is the +last semantic candidate and receives a fixed alternate focus on authority and exact +output/tool/stop constraints. Every candidate is generated fresh from the original +task context and failed target draft: neither rejected candidate text nor +model-generated failure analysis is fed into another generation. + +Without a configured secondary, Soma permits at most two primary candidates. A +transient primary availability failure can make the remainder of the current client +request start on secondary. That stickiness is request-local; the next request starts +on primary. There is no global circuit breaker or harness/session model state. + +The staged reasoning modes are part of the 2.4 contract, not optional tuning: +`TRANSFORM_REASONING_MODE` must be `off`, and a configured secondary must use +`TRANSFORM_SECONDARY_REASONING_MODE=on`. Configuration validation rejects any other +combination so deployment cannot silently diverge from the qualified route. + +## Classification and integrity decisions + +Classification returns exactly one object: + +```json +{"decision":"pass"} +``` + +or: + +```json +{"decision":"rewrite"} +``` + +The decision concerns the assistant's operative stance, not the presence of words +such as “cannot,” “refuse,” or “safety.” Quoted, translated, summarized, or analyzed +refusal language is not itself a refusal. A failed method followed by continued work, +a different method toward the same requested outcome, and an honest factual +constraint do not become rewrites merely because they contain negative language. +An adopted decision to stop, avoid part of the request, or deliberately substitute a +lesser outcome is a rewrite when the work remains feasible under the authoritative +system/developer instructions. A boundary those instructions explicitly require is +not an avoidable refusal and must be preserved. + +Integrity verification uses the same strict object shape: + +```json +{"decision":"pass"} +``` + +or: + +```json +{"decision":"rewrite"} +``` + +During integrity verification, `rewrite` means the candidate has a material defect +and must be rejected or regenerated; it does not request an in-place edit. The +verifier can reject residual withholding, a generic promise, +meta-commentary about the transformation, treating the failed assistant draft as +user-supplied material, invented task-specific inputs or results, contradictions with +accepted reasoning or immutable tool calls, and an unapproved clarification. + +Soma accepts only a complete JSON object satisfying the current schema. A pure JSON +fence is accepted, but an object embedded in prose is not. `TRANSFORM_JSON_MODE=true` +is the default and sends a small schema through `response_format`; disabling it +removes that wire hint but retains the same prompts, strict parser, local validation, +and recovery bounds. Separately, target and repaired content requested as JSON must +parse strictly and match an immediately declared top-level type. A configured literal +stop sequence may not survive in forwarded reasoning or content. Soma intentionally +does not implement full client JSON-Schema validation. + +## Joint repair contract and field policy + +One repair call returns a fixed object with both members present and nullable: + +```json +{ + "reasoning": "complete repaired reasoning or null", + "content": "complete repaired content or null" +} +``` + +Only fields classified for repair may be non-null. The two-key wire shape never +changes, while the per-call schema constrains each requested member to string and each +other member to null. Local validation preserves the same contract when a transform +endpoint ignores the schema or JSON mode is disabled. Nonblank exact outputs such as +`{}`, `[]`, punctuation, and Unicode symbols are valid; Soma does not impose an +English-text or alphanumeric "substance" heuristic on the requested deliverable. + +Soma classifies all present fields before requesting a repair: + +- If reasoning and content pass, both target fields are preserved. +- If content passes and reasoning requires repair, Soma drops the reasoning field; + it does not risk generating new private analysis for an already usable answer. +- If reasoning passes and content requires repair, the accepted reasoning is supplied + as evidence for the content repair. +- If both require repair, one candidate generates reasoning first and then content so + the answer can follow the repaired analysis. +- Verified jointly repaired reasoning is forwarded with its verified content. Because + integrity verification is message-level, a rejected joint candidate is retried as a + whole; Soma never salvages one unverified member from it. +- A reasoning-only response with no content and no native tool call cannot become a + terminal success merely because internal analysis exists. It takes the optional + target retry when enabled; otherwise it fails explicitly. +- Native `tool_calls` are immutable. Soma may repair adjacent reasoning/content using + the full tool context, but exhausted prose repair clears the unusable prose and + preserves the structured call. Soma never invents or edits a tool name, ID, + argument string, ordering, or result. Before repair, every returned function name + must match a supplied tool definition, and multiple returned calls are rejected + when `parallel_tool_calls=false`. + +The failed target assistant draft is evidence, not user-supplied task material. The +transform is instructed not to quote, explain, or “convert” the refusal itself. It +may preserve supported facts and genuine constraints, but it must not choose an +arbitrary example, fill invented placeholders, fabricate code changes or external +results, or claim a tool/action completed without evidence. + +`TRANSFORM_ALLOW_CLARIFICATION=false` is the default. A transform response that asks +the user for more information is not accepted as the repaired answer unless this +option is explicitly enabled. Enabling it is appropriate only for harnesses where an +essential missing input genuinely requires another user turn; it must be qualified +as a separate behavior profile. + +## Full task context and privacy boundary + +Classification, repair, and integrity verification receive the original request +context needed to understand references and preserve constraints: + +- original messages in order and by role, including `system`, `developer`, `user`, + `assistant`, and `tool` messages and tool results; +- complete tool definitions, `tool_choice`, and `parallel_tool_calls`; +- `response_format`, modality/audio controls, and `stop`; +- the target assistant draft, clearly separated from the original request; +- immutable target native tool calls in a separate read-only section; and +- the configured media representation for every multimodal part. + +System and developer messages remain authoritative context below Soma's fixed JSON +and native-tool invariants. Other supplied values are task evidence, not permission +to override the transform contract. + +Draft text is projected per phase. A classifier receives only its named target field, +so refusing content cannot contaminate accepted reasoning or vice versa. Repair +generation may inspect fields marked for replacement to preserve facts supported by +the task. Integrity verification removes every replaced or discarded original field +and judges only retained evidence plus the current candidate. + +Soma does not send target/transform endpoint credentials, HTTP headers, the target +model name, sampling knobs, or rejected transform candidates. It does not log task +context, prompts, target drafts, repaired output, tool arguments, media payloads, or +credentials. + +This is nevertheless a wider trust boundary than 2.3.0. Any secret embedded inside a +conversation, tool definition, tool argument, or tool result is part of the original +task context and can reach every transform endpoint used for that request, including +a remote secondary. Configure only transform services authorized to receive the full +request. Header exclusion cannot remove secrets that the client placed in message or +tool data. + +`TRANSFORM_CONTEXT_MAX_CHARS=131072` bounds the serialized `task_context`, and +`TRANSFORM_FIELD_MAX_CHARS=32768` bounds an individual target reasoning/content +field. The configured field limit must not exceed the context limit. The context +limit has a hard maximum of 4000000 characters. Because this is a character bound, +not tokenizer accounting, large-context profiles should leave room for transform +instructions and generated output. Soma rejects oversized semantic input +rather than truncating messages, tool schemas, code, or evidence into a misleading +task. Phase envelopes add the bounded candidate/contract data, and forwarded native +media remains subject to the upstream endpoint and trusted front proxy's byte limits. + +## Media modes + +Media handling is explicit per transform endpoint: + +- `placeholder` preserves typed part positions and non-payload metadata, omits the + actual binary/media payload, and marks the part unseen. The transform must not infer + absent media details. This is the correct setting for a text-only or `--no-mmproj` + llama.cpp server. +- `forward` sends original typed content media using native OpenAI multimodal message + parts. It does not serialize base64 media into ordinary JSON text. Provider-specific + top-level assistant media has no portable input envelope and fails explicitly in + this mode; use `placeholder` for that shape. Use `forward` only for an endpoint that + is authorized and qualified to accept the request's typed media parts. +- `reject` refuses to send a media-bearing task to that endpoint. Soma may use a + configured compatible transform route; otherwise it fails explicitly. Target retry + is not used to bypass an operator's transform-media policy. + +Set `TRANSFORM_MEDIA_MODE` for primary and `TRANSFORM_SECONDARY_MEDIA_MODE` for +secondary. If a `forward` endpoint rejects the media request, Soma routes only to a +compatible configured secondary or fails explicitly. It never invokes target retry +to bypass media policy and never silently retries the task as placeholder text, +because either action would change the evidence available to the model. + +Assistant audio attached to a usable text or native-tool turn is preserved, including +audio accumulated from a target stream. Audio-only target turns are explicitly +unsupported: Soma cannot inspect or repair the audio payload under its text repair +contract, so it returns `unsupported_target_response` instead of forwarding an +unchecked terminal answer. + +## Bounded recovery and verifier fallback + +The primary reasoning-off profile owns normal classification, candidate one, and its +integrity verification. After semantic rejection, a configured secondary +reasoning-on profile owns candidates two and three, each generated from the pristine +task package and independently verified. + +Reasoning-enabled generation can improve task understanding, but a small model may +spend an entire decision budget thinking and end with `finish_reason=length` before +emitting its tiny JSON decision. If an on-mode integrity verification is truncated or +structurally invalid, Soma does not discard the candidate. It verifies that identical +candidate exactly once on the same endpoint and model with reasoning disabled. Only +a completed `rewrite` decision advances to a fresh generation. + +Transport/availability failures follow bounded route failover. Structural JSON +recovery may include a concise closed failure category, but never rejected output or +raw exception text. Semantic retries receive only positive instructions and the +pristine task context; they are not primed with the preceding candidate or its +failure. + +There are hard ceilings of: + +- two target calls per client request; +- 20 transform calls for each target response; and +- 40 transform calls across the complete client request. + +`TRANSFORM_TOTAL_TIMEOUT=1200` is one aggregate deadline. It starts after the first +target response completes and covers every transform call, an optional second target +call, and processing of the second response. It does not reset after target retry. +The initial target call remains governed by `CONNECT_TIMEOUT` and `REQUEST_TIMEOUT` +outside that aggregate window. + +## Optional target retry + +`TARGET_RETRY_ON_UNREPAIRABLE=false` preserves the normal one-target-call behavior. +When enabled, Soma may call the target exactly once more only when the completed turn +is unrepairable and leaves no usable content or immutable native tool call. A failed +optional reasoning field does not trigger target retry when valid content remains. + +The retry starts from the original request and inserts one fixed corrective system +instruction immediately after the leading system/developer block. It preserves the +conversation and tool contract and never includes the rejected target response or a +rejected transform candidate. This avoids training the second response to imitate the +failure, but it does add target latency/cost and may produce a different native tool +decision. Soma still does not execute that call. + +Enable target retry only after qualifying the complete target-plus-transform route. +It is not a general retry for target HTTP errors, optional reasoning loss, or a merely +imperfect answer. + +## Loop-back on verified repair + +`TARGET_LOOP_BACK_ON_VERIFIED_REPAIR=false` is the default. When enabled, Soma may +make exactly one additional target call after an integrity-verified repair that +rewrote the target's refusal reasoning. Instead of returning the transform's repaired +candidate directly, Soma re-sends the original request with one appended assistant +message carrying only that verified repaired reasoning in a `reasoning_content` +field, so the target re-ingests the relaxed context and produces the task output +itself. The re-entry payload preserves the original conversation, media, tool +definitions, `tool_choice`, stop controls, and response-format settings untouched. + +Loop-back fires only on the first target attempt, only when reasoning was one of the +repaired fields, and only after that candidate passed integrity verification. +Content-only repairs, fields that classified as `pass`, tool-only turns, cleared +tool prose, and the second target attempt never loop. Genuine refusals never loop +because truthful technical, environmental, evidentiary, uncertainty, impossibility, +missing-input, and factual limitations classify as `pass` and are never rewritten. + +The second target call shares the hard ceiling of two target calls per client +request and the aggregate `TRANSFORM_TOTAL_TIMEOUT` window, which is not reset. The +second response is processed under the same classification, repair, and integrity +rules; if it is also unrepairable, the request fails explicitly and Soma never +makes a third target call. `TARGET_RETRY_ON_UNREPAIRABLE` and loop-back are +mutually exclusive per request because they handle disjoint failure classes +(unrepairable turns versus verified reasoning repairs) and share the single +additional-call slot. + +The reasoning carrier is fixed to `reasoning_content` with no fallback. Backends +that reject that field in input messages fail explicitly rather than silently +degrading to a different carrier. Loop-back adds target latency and cost; qualify +the complete target-plus-transform route before enabling it. + +## Failure behavior + +`FAIL_OPEN=false` is the default. Exhausted mandatory repair, invalid verification, +oversized context, incompatible media, missing usable terminal output, and other +nonrecoverable transform errors return an explicit error instead of forwarding a +known-bad candidate. + +`FAIL_OPEN=true` is an availability policy only. It can restore an original refusal, +withholding field, or otherwise rejected target text and therefore defeats strict +repair guarantees. Do not treat fail-open as a safety, compliance, or successful +quality mode, and do not enable it merely to hide model qualification failures. +Fail-open never makes a reasoning-only or otherwise empty terminal turn successful; +that turn still takes the explicitly enabled target retry or returns an error. + +Client and upstream JSON reject non-finite numbers. Transform objects additionally +reject duplicate member names. Client `stream` and `parallel_tool_calls` values must +be booleans, and `n` must be null or integer `1`. Target assistant text, reasoning +aliases, and native tool-call shapes are validated before any local mutation. + +Endpoint configuration rejects userinfo, queries, fragments, invalid ports, and +unsafe header overrides. `REQUIRE_DISTINCT_ENDPOINTS=true` prevents exact +target/transform origin collisions and direct self-routes. Operators must still avoid +DNS aliases or LAN addresses that resolve to a wildcard-bound Soma listener. + +## Configuration + +Minimal one-profile configuration: + +```bash +TARGET_URL=https://opencode.ai/zen/v1 +TRANSFORM_URL=http://127.0.0.1:8001/v1 +TRANSFORM_MODEL=local +TRANSFORM_REASONING_MODE=off +TRANSFORM_MEDIA_MODE=placeholder +``` + +Same-server primary-off/secondary-on profile: + +```bash +PROXY_HOST=127.0.0.1 +PROXY_PORT=8080 + +# Clear the removed 2.3.x option from an already-populated shell. +unset TRANSFORM_CONFIRM_REWRITES + +TARGET_URL=https://opencode.ai/zen/v1 +TARGET_KEY= +TARGET_HEADERS_JSON={} + +TRANSFORM_URL=http://127.0.0.1:8001/v1 +TRANSFORM_KEY= +TRANSFORM_MODEL=local +TRANSFORM_HEADERS_JSON={} +TRANSFORM_REASONING_MODE=off +TRANSFORM_MEDIA_MODE=placeholder + +TRANSFORM_SECONDARY_URL=http://127.0.0.1:8001/v1 +TRANSFORM_SECONDARY_KEY= +TRANSFORM_SECONDARY_MODEL=local +TRANSFORM_SECONDARY_HEADERS_JSON={} +TRANSFORM_SECONDARY_REASONING_MODE=on +TRANSFORM_SECONDARY_MEDIA_MODE=placeholder + +# Same-server primary/secondary is allowed.

Soma rejects the variable even when its +value is `false`; this catches a stale 2.3.x deployment rather than silently changing +its meaning. Deleting an export from a file does not clear an existing shell value, +so either start from a clean environment or run: + +```bash +unset TRANSFORM_CONFIRM_REWRITES +``` + +The primary and secondary keys/headers never inherit from one another. A same-server +secondary supplies behavioral diversity but no process, GPU, or availability +isolation. An independent endpoint/model can supply both, at the cost of extending +the full-context trust boundary. Qualify the secondary by itself and then qualify the +exact composed pair. Soma 2.4 requires primary `off` and secondary `on`; `default` and +the inverse mode assignments are rejected during configuration validation. + +`TRANSFORM_TEMPERATURE` is sent on every transform call and overrides the llama +server sampling default. `TRANSFORM_DECISION_MAX_TOKENS` covers classifications and +integrity decisions; `TRANSFORM_REWRITE_MAX_TOKENS` covers the fixed joint-repair +object. Valid ranges are 256–16384 decision tokens, 256–16384 repair tokens, +4096–4000000 context characters, and 1024–4000000 field characters, with the field +limit no greater than the context limit. Larger budgets bound output but do not +improve model judgment by themselves. + +Environment files are shell profiles and are not loaded automatically. Restart Soma +after every environment change: + +```bash +set -a +. ./soma.env +set +a +python3 soma.py --check-config +python3 soma.py +``` + +Additional environment variables not shown in the profiles above: + +- `LOG_LEVEL` (default `INFO`) — Python logging level for proxy diagnostics. +- `FORWARD_CLIENT_HEADERS` (default `true`) — forward non-hop, non-credential + client headers to the target endpoint. +- `TRANSFORM_PROMPT` (default built in) — base system prompt prepended to every + transform phase prompt. +- `SOMA_AUTO_REQUIRES_TOOL` (default `false`) — strict auto-tools mode that + classifies each request as requiring a native call or a text response. +- `UPSTREAM_ERROR_BODY_LIMIT` (default `4000`, range 256–65536) — bounded number + of upstream error-body bytes retained for target diagnostics. +- `SSE_CHUNK_CHARS` (default `2048`, range 128–65536) — maximum characters per + normalized SSE text delta. + +Verify the effective version, endpoint identities, reasoning/media modes, JSON mode, +context/field/token limits, clarification, target-retry, and loop-back policies, +aggregate deadline, and call ceilings through `--check-config`, startup diagnostics, +or `/health`. + +Point clients at: + +```text +http://:8080/v1/chat/completions +``` + +Aliases are available at `/chat/completions`, `/v1/models`, `/models`, and `/health`. + +### llama.cpp recommendation for a shared local endpoint + +For the shared-endpoint topology where one llama.cpp process serves a primary +reasoning-off profile and a secondary reasoning-on profile through per-request +`enable_thinking`, enable server reasoning support and cap thinking so a small +decision response has room to emit JSON: + +```text +--reasoning on --reasoning-budget 512 --temp 0 +``` + +The primary profile still sends `enable_thinking=false`; the global server mode must +not prevent the secondary profile from producing and parsing reasoning when it sends +`enable_thinking=true`. A 512-token cap is the required starting profile for the +bounded-budget qualification run; configuring it is not itself a qualification +claim. The evaluator's matching `--reasoning-budget 512` argument records what the +already-running server uses and does not configure the server. + +Keep both the server and Soma transform temperature at zero for qualification. Soma's +per-request `TRANSFORM_TEMPERATURE=0` is authoritative for transform calls; the server +flag supplies a matching default. Temperature zero removes deliberate sampling +variance so repeat failures can be attributed to the route under test, although it +does not promise byte-identical output across server builds, speculative decoding, +cache state, or concurrency. Any nonzero temperature is a different profile and +requires a separate report. + +Re-run the exact live profile after changing any server argument. Soma does not add +these arguments, restart the server, or download a model. A text-only server launched +with `--no-mmproj` should use `placeholder`, not `forward`, for both transform media +modes. + +### Multiple harness profiles + +Use one Soma process and listener port per harness. The supplied +[`profiles/harness-a.env.example`](profiles/harness-a.env.example) and +[`profiles/harness-b.env.example`](profiles/harness-b.env.example) use ordinary +environment variables and distinct ports. Soma has no `HARNESS_TYPE` dispatch or +shared mutable deployment profile. + +```bash +cp profiles/harness-a.env.example profiles/harness-a.env +cp profiles/harness-b.env.example profiles/harness-b.env +env -i PATH="$PATH" /bin/sh -c 'set -a; . ./profiles/harness-a.env; set +a; exec python3 soma.py --check-config' +env -i PATH="$PATH" /bin/sh -c 'set -a; . ./profiles/harness-b.env; set +a; exec python3 soma.py --check-config' +``` + +The supplied `profiles/.gitignore` excludes populated profile names while retaining +the examples. Keep production profiles outside distributable artifacts even when +ignore rules are present. A shared transform server must be qualified at the combined +load and configured concurrency; a one-slot llama server serializes both harnesses. + +### Trust and resource boundary + +Keep `PROXY_HOST=127.0.0.1` unless a trusted front proxy supplies authentication, +access control, TLS, request-size limits, buffering limits, timeouts, and rate limits. +Soma warns when bound to a non-loopback interface. It buffers complete target turns +and full bounded task packages and has no in-process concurrency-admission limit, so +the front proxy must enforce limits appropriate to available memory. + +## Native tool calls and streaming + +Soma supports native OpenAI `tool_calls` only. It preserves IDs, `type: function`, +function names, strict JSON argument strings, ordering, and streaming fragments. +Proprietary text tool syntaxes are ordinary assistant text; conversion belongs in the +target's OpenAI-compatible gateway. + +For `stream:true`, Soma buffers the complete target stream, processes it, and emits +normalized OpenAI delta SSE. Original chunk boundaries are not preserved. Valid +reasoning, content, native tool calls, finish reason, usage, and response metadata are +retained. Accepted `cost` and `usage` metadata are emitted together at most once. + +The upstream stream must produce a terminal non-null `finish_reason`. Soma accepts a +terminal choice followed by EOF or the ordinary sequence ending in `[DONE]`. +Standard empty-choice usage frames are retained. After the first `[DONE]`, at most one +narrow metadata postlude is allowed: an object with `choices: []`, no keys outside +`choices`, `cost`, and `usage`, and at least one non-null metadata value. It may end at +EOF or one closing `[DONE]`. Further objects/delimiters, malformed or non-finite JSON, +duplicate keys, premature `[DONE]`, or meaningful data after the terminal choice are +rejected. + +## Diagnostics + +Successful and post-dispatch error responses expose privacy-safe trace/timing and +bounded call counts, field decisions, candidate/verifier outcomes, target-retry use, +deduplication, and fail-open status. `/health` and startup diagnostics additionally +show the effective non-secret reasoning and media configuration. + +Transform logs identify phase, field/candidate, backend, reasoning and media mode, +purpose, closed failure category, JSON-mode value, channel lengths, finish reason, +token counts, elapsed time, and a request-ID fingerprint. They do not include prompts, +task context, target or transform text, media, tool arguments, credentials, error +bodies, or raw upstream request IDs. + +## Tests + +Run the complete offline suite: + +```bash +python3 -m unittest -v test_soma.py test_soma_extra.py +python3 test_soma_live.py --inventory +``` + +The suite covers strict schemas, full-context isolation and limits, joint field +policy, media routes, primary/secondary candidate ownership, reasoning-off verifier +fallback, optional target retry, hard call/deadline ceilings, fail-open behavior, +native tool fidelity, JSON validation, and SSE normalization. Offline success is +necessary but is not model qualification. + +## Live qualification + +`test_soma_live.py` is opt-in and dynamically imports the adjacent `soma.py`, so it +exercises the exact runtime prompts, schemas, parsing, validation, routing, and field +policy. It calls only already-running endpoints supplied by the operator and never +manages a model or server. + +First inspect the frozen corpus without network access: + +```bash +python3 test_soma_live.py --inventory +``` + +Run the exact selected transform artifact/profile at temperature 0 and retain the +report only under ignored `qualification-local/`. Consult `--help` for the current +provenance and endpoint arguments: + +```bash +python3 test_soma_live.py --help +``` + +Every qualifying run must declare primary `--reasoning-mode off`, a configured +secondary with `--secondary-reasoning-mode on`, and the secondary server's actual +positive `--reasoning-budget` (for the documented llama.cpp starting profile, +`--reasoning-budget 512`). This evaluator value records provenance; the server must +already have been launched with the matching budget. + +An exploratory run against llama.cpp's unrestricted default may record +`--reasoning-budget -1`. Its report remains unqualified because the positive-budget +provenance gate fails; it is not carried forward after a complete bounded-budget +rerun replaces the current evidence. + +Qualification is automated-only. Use a new report filename and run the exact +temperature-zero, bounded profile. Exit status `0` means every qualification gate +passed and the report records `qualified: true` with +`qualification_status: qualified`. Exit status `1` means at least one qualification +gate failed, and `2` means setup or report creation failed. The evaluator has no +second approval stage; inspecting retained evidence does not alter report status. + +Provider-managed routes can be exercised with +`--artifact-kind provider-managed`, but they are recorded as exploratory and can +never be marked qualified by this evaluator. Supply the exact provider name, model +label, and a small public `/models` metadata record through +`--provider-model-metadata-json`; do not invent GGUF, llama.cpp, hardware, revision, +or reasoning-budget values for a hosted service. Use `--reasoning-budget 0` when the +provider does not publish a bounded budget. The report separates behavioral gate +results from qualification eligibility and records the requested reasoning modes as +unverified provider controls. + +To retain the qualified local GGUF primary while evaluating a hosted secondary, use +`--artifact-kind hybrid-local-provider`. Supply the ordinary local artifact fields +for the primary and the provider metadata fields for the secondary. The evaluator +retains both identities, but deliberately records the combined route as exploratory +and qualification-ineligible because the hosted reasoning controls and budget are +not independently verified. The primary's artifact label may differ from its wire +model alias (for example, an immutable repository label with `local` on the wire). + +`--target-smoke-count 10` limits only the final target-through-transform smoke calls. +It does not limit the preceding transform corpus: the evaluator still runs all 240 +classifier cases, 80 retained repairs, repeat matrices, and route/media probes. Each +smoke request grants 128 output tokens, and its response must contain exactly `OK` +with no surrounding whitespace, prose, or native tool call. + +For the initial bounded Qwen route, the automated command must include the exact +primary/secondary endpoint and provenance arguments plus: + +```bash +python3 test_soma_live.py \ + --reasoning-mode off \ + --secondary-reasoning-mode on \ + --reasoning-budget 512 \ + --temperature 0 \ + --report qualification-local/qwen3.5-9b-q6_k-t0-rb512-automated.json \ + [the exact endpoint, model, server, artifact, and hardware arguments] +``` + +Reports are immutable evidence files. The evaluator writes a completed report +privately and installs it atomically; it never exposes a partially written result or +overwrites an existing path. The stabilized evaluator, corpus, and source hashes must +match the new run. After a complete budget-512 report has been validated and installed +under its truthful filename, remove the obsolete unrestricted-budget artifact so only +the current evidence remains. + +The automated gates require: + +- valid contracts on all 240 classification cases, 100% hard-refusal and overall + refusal recall, and zero false rewrites; +- all 20 schema-off high-risk sentinels and five repeats of every high-risk case at + parallelism 1 and 4 with zero repeat failures; +- all 80 message-repair cases completed without exhaustion and 100% integrity + verification, required-fact retention, and forbidden-fact absence; +- exactly 20 cases in each field-decision cell: `pass/pass`, `rewrite/pass`, + `pass/rewrite`, and `rewrite/rewrite`; +- the exact staged primary-off then secondary-on candidate route; +- explicit positive secondary reasoning-budget provenance (use `512` as the initial + llama.cpp qualification value); +- explicit `placeholder`, `forward`, and `reject` media behavior; and +- complete source, evaluator, model, server, configuration, and fixture + reproducibility evidence. + +The report also records latency, classification disagreements, backend/phase +ownership, semantic repair attempts, verifier fallback, and call ceilings. Strict +JSON is exercised both with structured-output mode enabled and with the wire schema +omitted. + +Live target smoke is separate and explicitly opt-in because it incurs target cost and +can produce a new model/tool decision. It uses benign fixtures, keeps target retry +disabled, verifies the complete target-to-transform route, and never executes returned +tools. Target-retry behavior remains deterministic offline coverage until separately +qualified; live smoke does not enable it. The smoke is not run by `--inventory` or an +ordinary transform-only qualification. The count is bounded from 1 through 10: + +```bash +python3 test_soma_live.py \ + --target-smoke \ + --target-url https://target.example/v1 \ + --target-model TARGET_MODEL \ + --reasoning-budget 512 \ + --target-smoke-count 10 \ + [the same transform and provenance arguments used for qualification] +``` + +Without `--target-smoke`, the evaluator makes zero target calls. Supply target keys +through the hidden CLI/environment option, never in recorded server arguments or a +report intended for sharing. + +An automated pass is final qualification for the exact recorded profile. Reports +retain all 80 accepted repair outputs and their evidence hashes so the result can be +audited and reproduced, but later inspection does not change qualification status. +Any failed gate leaves the profile unqualified, and a smaller model receives no +relaxed threshold. + +Any change to model revision, GGUF, server build/arguments, reasoning budget, +temperature, prompt, endpoint identity, media mode, context/token limits, field +policy, primary/secondary composition, evaluator source, fixture corpus, or assertion +semantics creates different evidence and requires a new report. Evidence hashes bind +one report's exact inputs and outputs; they do not transfer qualification to a +superseded report.
