Fixed by using + `internal_user_viewer`. Note: key-level `allowed_routes` does **not** help — in `route_checks.py` + it is only consulted as a later `elif`, so a role branch that already passed never reaches it. +2. **`async_logging_hook` is only called from the success handler.** The failure path applied no + redaction at all, so any forced failure shipped raw prompts to Langfuse.

Cross-user +caching today is worth **4.6%**: noise. Moving three lines is worth the entire 9.6×. + +Two corrections this produced. An earlier "32% hit rate" was measured with a byte-identical payload, +which silently modelled one user, one machine, one day — the cross-user number was always the one +that mattered. And LiteLLM bills cached tokens correctly ($0.0038 hit vs $0.0364 miss, reconciling +to Google's published $0.03/1M cached vs $0.30/1M input), so there is no billing bug: we are not +over-debiting users. + +**Explicit caching works but is dangerous before the prefix is stable.** A cache_control marker got +121,039 of 121,044 tokens cached, 3/3 requests, guaranteed rather than best-effort. But explicit +cache storage is $1.00/1M tokens/hour — a fixed **$2.91/day per distinct prefix**. With today's +per-user prefixes that is one cache per user: 200 users = **$582/day** to save $0.03 a request, +because the cost scales with users while the saving scales with requests. Sequencing is therefore +locked: stabilize the prefix → then gateway-injected explicit caching (with a hard cap on live +caches, storage metered inside the $50/day ceiling, cache identity derived from a prefix hash so a +release invalidates it automatically, and an alarm on sustained `cached_tokens` drop — a stale cache +does not error, it silently costs 10×) → then set grant/ceiling/tpm against $0.0037/req. + +**RESOLVED 2026-08-07 — the ceiling is structural, and the prefix fix is worth ~1.18×, not 9.6×.** +Tool declarations serialize **after** `systemInstruction` on the wire, so a difference *anywhere* in +`systemInstruction` — including its final byte — earns zero credit for the tool block.

Two independent lines agree: +the client's own captured payload predicted 5.8% cacheable before the fix, and 5.1% was measured. + +On this repo's **real** payload the gain is smaller than a synthetic fixture suggests, because tools +dominate: system prompt 59,163 chars vs tools 182,122 chars, so **~75% of the static payload is +permanently out of reach of any reordering inside `input.system`**. Cacheable span of +`systemInstruction` goes 13,919 → 58,817 chars (4.2× on that block), i.e. 5.8% → ~22% of the full +static payload after the measured 89-94% realization factor — about **$0.01715 → $0.01448/req, a +15.6% saving (1.18×)**, and only in the cases where `systemInstruction` varies at all (different +cwd, a new day, a different project, another user). Within one session it was already byte-stable. + +So the reordering is real, free, and non-worsening — but it is not the headline. **The remaining +upside now belongs entirely to explicit caching**, which caches the whole payload including tools +regardless of variance: ~$0.00187/req, ~133 requests/day at a $0.25 grant. That is a much cleaner +decision boundary than we had, and it raises explicit caching's value well above the earlier +break-even estimate. + +**A sweep of the stable head found two more prefix-breakers, one fixed and one bigger.** Skills were +sorted with `localeCompare`, whose default follows the runtime's LANG/ICU data — so two machines +emitted the same skills in a different order and shared no prefix at all. It needed fixing in *two* +places (`SystemPrompt.skills()` orders the auto-loaded bodies; `Skill.fmt()` re-sorts independently +and is the one that reaches the prompt), and correcting either alone accomplishes nothing. Fixed to +codepoint order. + +The bigger one is **not** fixed: `Skill.fmt()` emits `` as an absolute `file://` URL +carrying the user's home directory and worktree path, first occurring at char **40,850** — *earlier* +than `` at 58,817. So for cross-user sharing the skill paths, not ``, are the first +differing byte. Even a user with zero project skills gets a machine-specific path, because built-ins +resolve to `.../packages/opencode/%3Cbuilt-in%3E` instead of taking the `builtin:` branch that +already exists on that line. Measured against the 241,285-char static payload: + +| | Cacheable head | Share | +|---|---:|---:| +| Before the reorder | 13,919 | 5.8% | +| Today (reorder + codepoint sorts) | 40,850 | 16.9% | +| If skill locations were machine-independent | 58,817 | 24.4% | + +So the reorder did help cross-user sharing (13,919 → 40,850) and the remaining ~7.5 points is one +fix away — but it is not a pure byte-order change (it alters what the model sees), so it needs the +same behavioural verification the `` move got. The rest of the head is clean: no dates, epochs, +UUIDs, tmp paths, ports, or unordered iteration ahead of ``. + +Deferred follow-up, flagged not attempted: getting the tool block into a *shared* prefix requires +`systemInstruction` to be byte-identical across requests, which means moving ``, AGENTS.md and +memory into `contents` — the exact placement that caused the documented date-echo regression. One +nuance for whoever picks it up: that regression came from appending the date to the **trailing** user +message every turn; a synthetic **first** user message is a different placement and may not echo — +but it sits inside the conversation prefix, so it needs its own measurement, not an assumption. + +**Not done, and required before any public deploy:** everything in "Legal gate" below (unchanged and +still blocking), plus the deploy gates in the gateway README — TLS ingress with a route allowlist and +a whole-body size cap, >1 worker, Vertex-side quota + GCP Spend Cap Budget as the hard backstop, and +real secret management.

Not reusable here beyond its SSE-passthrough and redaction patterns. | +| "altimate-backend deploys a LiteLLM gateway" | There is **no standalone LiteLLM proxy deployment**. LiteLLM is used as an **in-process Python SDK** (`litellm.acompletion()`, pinned `1.83.0`) inside altimate-backend behind `POST /agents/v1/chat/completions` — an authenticated, tenant-scoped, OpenAI-compatible route. Models today: Sonnet 4.6 (Anthropic → Bedrock fallback) and GPT-5.5 (Azure). **Zero Vertex/Gemini plumbing exists.** The free tier there (`FREE100`, 10M-token grant) requires email signup; rate limiting is an in-memory per-process token bucket (documented in-code as broken under multi-replica); the security scan in `chat.py` is currently commented out. | +| "Big Pickle is a special system" | It's just a models.dev registry entry (`provider "opencode"`, OpenAI-compatible `https://opencode.ai/zen/v1`) with `cost: 0`, plus one custom loader: no API key found → strip all paid models → autoload with a sentinel `apiKey: "public"`. The endpoint simply doesn't validate keys for $0 models. And per opencode's own docs, Zen access is nominally account-backed (log in, get a key) — the anonymous path works because the server tolerates it for free models. | + +What we DO have, and it's a lot: + +- **Client-side template is 90% built.** Our fork already ships a custom provider (`altimate-backend` / model `altimate-default`, "Altimate LLM Gateway") with: a static `database[...]` injection block (`packages/opencode/src/provider/provider.ts:1423`), a `CUSTOM_LOADERS` entry resolving baseURL/key/headers (`provider.ts:332`), a TUI provider-priority row (`packages/tui/src/component/dialog-provider.tsx` — slot 4 is literally **reserved for the free interstitial**), and `DialogBigPickleConfirm` (`altimate-onboarding.tsx`) — a ready-made "free but with caveats" confirm dialog to clone. The telemetry enum already tracks `big_pickle` as a distinct provider choice. +- **A pattern for pseudonymous identity** — but not the artifact itself. `~/.altimate/machine-id` exists (crypto-random UUID, persisted), but it is publicly documented as serving *only* aggregate telemetry (`docs/docs/reference/telemetry.md`). Reusing it as a service credential would contradict that statement and link the telemetry and inference datasets. The free tier gets its **own gateway-scoped install secret**, minted the same way, stored via the existing `Auth` store (mode `0600`). +- **Langfuse is live.** altimate-backend uses Langfuse SDK v3 (OTel-based) with `LANGFUSE_HOST` configurable (`app/utils/langfuse_utils.py`); LiteLLM proxy has a native `langfuse` success callback (with caveats — see Traces). +- **An OpenAI-compatible surface + billing template.** `/agents/v1/chat/completions` and `verify_token_allowance`/`bill_tokens` are useful shape references even though free-tier traffic will not run through them. + +## External research: what the market does (full report: vault copy "Deep Research — No-Signup Free LLM Endpoint") + +- **Nobody ships truly anonymous unauthenticated inference.** OpenCode Zen, Cline, Gemini CLI (60 rpm / 1,000 req/day via Google OAuth), Qwen Code (free OAuth tier cut 1,000→100/day, then scheduled for shutdown — a warning about building on others' promos), OpenRouter `:free` (50 req/day, 1,000/day after a $10 deposit) — all bind free usage to *some* account or key. The viable no-signup pattern is: **silently issue a pseudonymous credential on first run and treat it as an abuse control, not identity.** +- **Two abuse planes.** (1) *Farming*: many installs / copied tokens / container fleets. With no signup and no attestation, farming is **unavoidable** — the design goal is to bound its cost per unit time, not to establish "one human." (2) *Proxy abuse*: normal-looking requests using us as a generic free LLM API. Model pinning limits damage but does not eliminate this — a free Flash chat endpoint is inherently a useful generic API; shape checks and user-agent checks are spoofable. Budget ceilings are the real control. +- **Spend control is layered, and nothing external is synchronous.** GCP's preview **Spend Cap Budget** (supports Vertex AI) pauses new usage after a monthly cost threshold — but it is delayed, lets in-flight requests finish, and can overshoot: a disaster backstop, not enforcement. Gemini pay-as-you-go runs on **Dynamic Shared Quota with no predefined per-project ceiling you can rely on** — there is no "physics-level" quota cap. Synchronous enforcement must live in the gateway: fail-closed budget checks with worst-case cost reserved before dispatch. +- **Pricing (Vertex, per 1M tokens, standard tier, as researched 2026-08):** gemini-2.5-flash $0.30 in / $2.50 out (cached in $0.03); gemini-2.5-flash-lite $0.10 / $0.40; gemini-3-flash-preview $0.50 / $3.00; gemini-3.1-flash-lite $0.25 / $1.50. Implicit context caching discounts cached input 90%, but hit rates depend on stable prefixes and reuse timing — treat as upside, not plan. **Pin an exact GA model ID and price table at deploy time**; budget enforcement that depends on pricing cannot ride a `latest` alias. +- **Vertex data governance is favorable but not absolute:** Google does not use customer data to train its models by default, but may retain prompts for abuse monitoring and uses project-scoped caching. More important — see Legal below — Google's service terms constrain what *we* may do with Gemini **outputs**. +- **Trace collection needs disclosure, not silence.** Big Pickle's own model card says data "may be used to improve the model"; Cline/NVIDIA/LongCat all disclose per-model.

The honest capability caveats (from review): + +| LiteLLM capability | Caveat | +|---|---| +| Budgets with reset | Reset checks run on a cadence (~10 min default) — "daily reset at midnight" is approximate | +| Redis distributed limits | Bounded drift; stale-counter recovery can undercount → use fail-closed mode (authoritative DB validation) | +| Global `max_budget` | Software accounting, not a billing guarantee — pair with Spend Cap Budget | +| "Ignore client model" | Not automatic — key-scoped alias allowlist + pre-call hook rewriting | +| 429s with reset time | Not guaranteed; build a normalized error taxonomy (daily budget vs. rpm/tpm vs. concurrency vs. provider 429 vs. maintenance) and test each | +| Langfuse callback | Doesn't map our `X-Session-Id` header or key metadata to trace user/session by itself — needs a server hook; built-in masking is whole-blob, typed secret redaction is custom code | + +### Identity & keys (the Sybil-honest version) + +- The install "identity" is a client-generated random secret — it proves nothing. An attacker can mint unlimited ones, so **never treat per-install limits as a global bound**, and never let keys accumulate: first-draft "permanent key, daily reset" would let an attacker stockpile keys slowly under issuance limits and use the whole hoard daily, forever. +- Design: **stable budget principal + short-lived rotating keys.** The principal (keyed by hashed install secret, keyed-rotating-HMAC for any stored IP data) carries hourly/daily/monthly budgets; virtual keys expire in days and are rotated on re-registration *without* resetting the principal's spend. Re-registration never returns an old key (LiteLLM stores only key hashes — it can't, and shouldn't). +- **Progressive grants:** new installs start small (e.g. $0.10–0.25/day) and grow with benign usage age; inactivity expires principals. +- Loose IP/subnet velocity limits apply to **both** registration and inference (IPv6 normalized to /64, trusted-proxy aware) — a signal, not identity. +- Worst-case spend is then bounded per unit time by: (principal budgets × active principals) ∩ global daily wallet ∩ Spend Cap Budget — with the global wallet sized so that even a successful farming run is a bad day, not a bad month. Wallet exhaustion is also a DoS vector against legitimate users; alert early (50%) so tightening beats tripping. + +### Abuse controls beyond spend + +- **Inline kill switch** — a flag that makes LiteLLM reject all free-tier inference immediately. Stopping issuance alone leaves every outstanding key live for days. +- **Cloud Armor/WAF** in front of the edge: malformed/oversized bodies, connection limits, streaming duration caps, basic bot rules. +- **Gemini safety policy** configured; policy-violation strikes per principal → revocation. +- **Separate cost ceilings for the infra itself** (Langfuse storage, Redis/Postgres, egress) — the LLM bill is not the only bill. +- Deferred until evidence demands: proof-of-work at registration, Turnstile, behavioral scoring. Log enough (principal, IP-HMAC, ASN, velocity, token profiles) to add them fast. + +### Cost budgeting (corrected) + +A heavy agent user ≈ 5M input + 300k output tokens/day ≈ **$2.25/day** on gemini-2.5-flash uncapped; even a perfect cache hit rate only brings it to ~$0.90/day, and real hit rates are worse — so a $1/day cap **binds** for heavy users on Flash. Options, to be decided from beta token profiles: (a) flash-lite default (~$0.62/day heavy, cap rarely binds) with Flash behind a smaller budget share; (b) Flash default with the cap as the honest limiter, communicated in the interstitial ("generous daily limit"). Either way: progressive grants keep the *average* cost per install far below the cap, and capacity planning uses measured beta numbers plus infra costs — not this napkin. + +### Traces + +- LiteLLM success hook → our Langfuse: `trace_user_id` = principal id (server-derived, never client-supplied), session = validated + namespaced client session id, tag `policy_version`; strip any client-sent Langfuse/metadata overrides. +- **v1 stores usage + metadata at 100%; full prompt/completion payloads start sampled and gated** on: custom typed secret-redaction masker (API keys, private keys, `.env` patterns, JWTs, DB URLs → typed placeholders) proven on real traffic, retention job in place (OSS Langfuse has no automated retention), deletion path documented. Widen to 100% payloads only after those hold and legal signs off on the use scope. +- **Disclosure** (Big Pickle pattern), in the confirm interstitial and docs: *"Free model — requests and responses are logged and may be used to improve Altimate's products and services.

No signup required."* Wording reviewed by counsel together with the output-use question; do not promise "improve the model" unless training on outputs is cleared. +- Later value, in the order of legal confidence: eval sets from real agent trajectories, failure clustering, routing/product analytics; SFT/preference data **only if** the Gemini output-use restriction is resolved. + +### Client-side changes (clone the existing template, ~7 files) + +1. `packages/opencode/src/provider/provider.ts` — new `database["altimate-free"]` block ($0-cost model `gemini-flash-free`) + `CUSTOM_LOADERS["altimate-free"]`. **The loader only reads an existing credential** (autoloads if present); it never registers. Registration — minting the install secret and calling `/register` — happens exclusively in the affirmative path of the disclosure dialog, so no identifier leaves the machine before consent and startup gains no network dependency. +2. `packages/tui/src/component/dialog-provider.tsx` — occupy reserved priority slot 4. +3. `packages/tui/src/component/altimate-onboarding.tsx` — clone `DialogBigPickleConfirm` → disclosure interstitial (default No stays); on Yes: register → store key via `Auth` store (0600) → select model. +4. `packages/tui/src/component/dialog-model.tsx` — free row in the picker (needs-setup style until registered). +5. `packages/opencode/src/altimate/telemetry/index.ts` — extend `provider_selected` enum + `classifyProvider()`. Telemetry keeps its own machine-id; the free-tier install secret is separate by design. +6. `packages/opencode/src/altimate/api/` — small client for `/register` + key refresh (silent rotation on 401/expiry). +7. `docs/docs/configure/providers.md` + `docs/docs/reference/telemetry.md` — document the model, the disclosure, and the new identifier (and fix the existing `altimate` vs `altimate-backend` id mismatch while there). + +### What we're explicitly NOT doing + +- **Not extending `altimate-router`** — wrong shape (local, Anthropic-only, single-tenant). +- **Not routing free traffic or key issuance through altimate-backend / prod** — isolation is the point; prod never holds the LiteLLM admin credential. +- **Not hand-building a proxy** — LiteLLM + a thin issuer + hooks covers it. +- **Not shipping any credential in the open-source binary** — only the gateway URL and the registration protocol are public. +- **Not designing v1 around the paid/BYO-key "graduation path"** — plausible later, but it must not widen the v1 security boundary. + +## Phased plan + +| Phase | Work | Exit criteria | +|---|---|---| +| **0 — Legal + infra** (~1 wk) | Counsel + GCP account team: output-use, proxying, credits, under-18 clause, disclosure wording.

Two patterns dominate, and both are worth carrying into any future security-sensitive +work here. + +**1. A vulnerability class reopens through a new entrance each time you fix a field.** The +credential-exfiltration bug was closed four separate times: a project config could redirect +`baseURL`, then `npm` (which `getSDK()` *imports*, handing it the stored key), then +`variants.fast.options.baseURL` through a third consumer that read `config.provider[id]` directly, +and finally a **ModelsDev registry record** named `altimate-free` winning the conditional +registration — not project config at all, but remote data refreshed at runtime. Only the fourth fix +was structural: deny the id where config is *read*, so every consumer inherits it, including ones +that do not exist yet. The lesson is that "fix the field the reviewer named" is not a fix. + +**2. Tests that pass against the bug they target.** Seven shipped across the client rounds, plus +several on the gateway, *including tests written specifically to fix earlier false greens*: + +- a mode assertion that passed against the very non-atomic writer it targeted (the discriminator is + the **inode**, since the old writer also ends at `0600` after its `chmod`) +- a fixture that made `metadata["headers"]` and `proxy_server_request["headers"]` the **same dict + object**, so it could never distinguish the two copies it asserted about +- a migration fake that iterated a dict in insertion order, so it could not exhibit the page + instability it existed to detect +- a role test covering only fresh creation, while the bug was that *existing* principals were never + reconciled +- `<= 3` where the buggy single-pass version satisfies it with 1 — upper bounds assert termination, + exact counts discriminate +- a "different token" built as `token.slice(0,-1) + "0"`, which reconstructs the original ~1 in 16 + times (measured 7.06% over 10,000 tokens against the 6.25% the hex alphabet predicts) + +The only thing that reliably caught these was **revert the fix, run the test, watch it go red**. And +a late refinement: two near-misses were invalid *experiments* rather than invalid tests — a revert +that threw a `ReferenceError` aborted before the assertion could discriminate, and a heredoc silently +ate invisible PUA literals so both comparators agreed. When a revert makes a test pass, first prove +the revert actually reached the code. + +The strongest form of that rule, earned from three further instances during the final verification +pass: **an experiment must be shown to have run in the same environment as the thing it claims to +characterise, not merely to have executed.** A `cd` inside a compound command made `git show` emit +zero-byte files that formatted cleanly; `bunx` fetched a floating tool version instead of the pinned +one; and baselining by copying files to `/tmp` resolved *no* config at all, which inverted the +conclusion — it made pre-existing formatting violations look self-inflicted. A green result from a +config-less directory, an empty file, or an aborted code path is indistinguishable from a real pass. + +## The carrier enumeration (2026-08-18) — and a correction to what "verified" meant + +After four review rounds had each found *one more* place a secret travels into the trace, we stopped +patching and enumerated the whole surface from the pinned image's source. That enumeration found +**seven more client-controlled values reaching Langfuse in the clear**, in a trace already hardened +four times. Full 25-row table with source citations lives in the gateway README under +*The secret carriers into Langfuse*; summary: + +- **5 already masked** — re-verified by canary this round rather than taken on trust. +- **3 masked by accident** — nothing *we* do covers them; upstream happens to. Langfuse skips one + header copy *by name*, computes `clean_headers` from another and then discards the result (dead + code upstream), and pops `secret_fields` before use. A LiteLLM bump can flip any of these with no + signal, and our masking of the third is currently a no-op that protects nothing. +- **7 not masked** — arbitrary body-metadata keys, a *fourth* header copy, client-minted tags, + `langfuse_*` values surviving under a copied key, `user` → `user_api_key_end_user_id`, User-Agent + (twice, including into `trace.tags`), and the session id landing in `trace.id`. All fixed. + +**Root cause behind most of them:** at logging time `metadata` is not on `model_call_details` at all +— it lives only under `litellm_params`, which is where Langfuse reads it. Our auth-header masking +read `kwargs["metadata"]` and therefore masked nothing on either path. Reading the source would not +have revealed this; only dumping a live record did. + +**A trace-write primitive, exploitable anonymously, now closed.** Body +`metadata: {"existing_trace_id": …}` made Langfuse write our generation into a caller-named trace. +Demonstrated live with an ordinary key from anonymous `/register` over the one public route: it +produced a trace with a caller-chosen name, `userId: null`, `tags: []`. Two consequences, the second +worse — a caller can write into a trace it names, **and** the write escapes `tier:free`, so it is +invisible to the query we use to review free-tier usage. The same channel carried `trace_name`, +`prompt`, `update_trace_keys`, `parent_observation_id`, `debug_langfuse`, and `mask_input/output`; +all dropped, plus a second path via body `litellm_metadata` which the proxy merges *after* the +snapshot. + +**The correction that matters most.** Six of the seven were in `observations[0].metadata`. Our +verification — including the first end-to-end check, which was reported upward as confirmation that +redaction worked — searched `input`/`output` of an object from the **list** endpoint, where +`observations` is a list of id *strings* and trace metadata is `{}`. The data was never in the object +being searched, so that assertion was **unfalsifiable for the entire class**, whatever was planted. +The earlier results were correct but narrower than stated: the evidence supported "no secret material +in `input`/`output`", not "no secret material in the trace". Restate them that way rather than +retract them. Checking a trace now means fetching `/api/public/traces/`, which embeds +observations, and searching the whole document. + +**A fourth false-green mechanism, and the first that was timing-dependent:** Langfuse ingests trace +and observation separately, so for a few seconds the full document has `observations: []`. A new test +passed against reverted code purely because it looked before the metadata existed. "Looked too early" +is indistinguishable from a real pass. + +**Still open, and deliberately out of scope:** the Postgres **spend logs** are unexamined and are +known to hold unmasked `messages` and `response` — `standard_logging_object` is built *before* the +logging hook. Langfuse never reads those fields, so they do not reach the trace, but they are in our +database. That is a separate surface needing its own enumeration. + +**Is the set complete? No — larger.** What is defensible: the set of fields Langfuse writes is closed +and read off the pinned image, so a new carrier must arrive through one of them; and the verification +method can now actually fail. What falls short: three carriers rest on upstream accident, the strip +is necessarily subtractive (an allowlist cannot work, since the router legitimately adds metadata keys +after our hook), and only the trace store was enumerated. What would justify "complete": a **negative +test that fails when a *new* carrier appears** — plant a canary in every client-reachable input and +assert the stored document contains none of them, run on every image bump — plus the same treatment +for spend logs. + +## Round 5: the enumeration held, the per-field claims did not + +A Codex review *of the enumeration* found four more issues, which settles the completeness question +empirically. The structural result is the useful part: **both new carriers were inside fields already +classified as masked**, not new fields. Field-level enumeration held; per-field claims were too coarse. + +- **Dictionary KEYS were never masked** — only values. `tools[].function.parameters.properties` is a + caller-authored object whose *keys* are field names, so a secret used as a property name was stored + in the clear beside its masked value, and the request-path scan ignored keys too, so no + `redacted:` tag fired either. +- **`redact_messages` covered a named four** (`content`, `tool_calls`, `function_call`, `name`). + Everything else in a caller-authored message went raw: `tool_call_id`, `reasoning_content`, + `thinking_blocks`, and any unknown key the schema accepts — three of which were listed as + secret-bearing *elsewhere in our own code*. +- **The fail-closed path left metadata intact, and a caller can trigger it deliberately** — masking + raises past 24 levels of nesting, and a permitted tool schema can be nested that deep, so an + attacker forces the failure and `_withhold` blanks everything except the widest carrier. +- **A strip rule deleted by remembered name.** A name in the caller's snapshot proves they supplied + the *name*, not that the value is still theirs; the proxy later writes the authoritative hashed + token to that key, and the rule would have deleted it. Provenance was proven; deletion was not. + +**Verification lesson worth more than the fixes: check whose placeholder it is.** The failure-text +carrier appeared masked in the trace — as bare `REDACTED`, which is *LiteLLM's* placeholder, not +ours. Recording that as our coverage would have made a future `LITELLM_DISABLE_REDACT_SECRETS=true` +a silent unmasking. Setting that variable and re-running showed our own typed placeholder underneath, +so both layers cover it independently. + +**A fifth false-green mechanism:** a test using a hand-written stand-in for a pydantic model passed +against reverted code, because the walk it was testing only fires on real models — the same shape as +an earlier `Delta` fixture. A stand-in cannot exercise code that keys off the real type. + +## The sweep test — how this stopped + +`issuer/tests/test_carrier_sweep.py` plants a distinct canary in **23 client-reachable positions** +(dict keys as well as values at depth, every message field including unknown ones and +`tool_call_id`, body-metadata keys/values/nesting, `litellm_metadata`, header names *and* values, +tool-schema names/descriptions/property-names/enum-values/defaults, plus `user`, `stop`, +`User-Agent`, session id) and asserts the **stored trace document** contains none of them. It fetches +the full trace so observations are embedded, waits for the observation rather than asserting into the +ingestion gap, and **fails rather than skips** without Langfuse credentials. Runbook command sits +next to the enumeration in the gateway README. It costs ~$0.0002 a run, so running it on every image +bump is free in practice — which matters, because three carriers are covered by upstream accident. + +**First run found nothing new** — zero raw canaries across all 23 positions, with 29 of our +placeholders visible, so masking was demonstrably running rather than the payload having missed. The +field-level enumeration held, and so did the positional expansion of it. + +But it did not *pass* first time, and the reason is the better result: the request included an orphan +`role: "tool"` message, so the whole sweep silently ran down the **failure** path where upstream's +redaction masks error text first. The attribution check caught it — four bare `REDACTED` markers that +were not ours. The sweep now asserts `status_code == 200`, because a sweep that quietly runs on the +failure path is weaker than it looks and nothing else would have said so. + +**Attribution lives in the assertion, not the prose:** the sweep strips our `[REDACTED:*]` +placeholders and fails on any remaining bare `REDACTED`, since that is upstream's and would unmask on +an env-var change. + +**The anti-vacuity exercise produced two more fixes**, which is the argument for always doing it: +- The withhold revert came back **GREEN** — every canary it planted was covered by some *other* part + of `_withhold`, so removing the metadata branch changed nothing observable. It needed a canary that + reaches metadata *and* survives the request-path strip (`User-Agent`, which the proxy writes into + metadata after the caller's snapshot is taken). A test that cannot observe the thing it names is + the same class of defect as a false green. +- The strip revert exposed a real missing second layer: a metadata **key** whose *name* is a secret. + `_mask_metadata_values` rewrote what keys pointed at, never the key itself. Not a live leak — the + strip removes those keys first — but the defence in depth was absent, and only the revert showed it. + +### What the sweep does NOT cover + +Written down rather than assumed: + +1. **Positions no client can reach today** (`_arealtime` input, non-chat output branches, guardrail + and grounding spans). Enabling a route or a guardrail widens the surface without changing a sweep + result — the sweep cannot tell you that you enabled something. +2. **The Postgres spend logs.** Trace store only. `standard_logging_object` is built before the + logging hook and carries unmasked `messages`. +3. **Secret *shapes* we have no rule for.** Every canary is AWS-key shaped because that rule is + unambiguous. The sweep proves **positions** are masked; it says nothing about pattern coverage, and + a credential shape absent from `_RULES` passes all 23 positions cleanly. **This is now the largest + uncovered thing on this surface, and it is a different axis from the carrier work.** +4. **Masking quality** — absence of the canary, not whether the placeholder keeps a trace debuggable. + +The recommendation from the agent that built it, which I endorse: do not run another enumeration +round against the trace store. Point the next one at the pattern set. + +## Notes for a human reviewer + +- **18 of 39 changed `.ts`/`.tsx` files fail `prettier`, and it is pre-existing** — verified by + baselining in-repo rather than in a temp copy (see the `/tmp` trap above). None of the lines added + by this work are affected, and no CI workflow or git hook runs `prettier --check` (`.husky` has + only a pre-push `typecheck`), so it is cosmetic. Called out because a reviewer running prettier + locally will see a large spurious diff and should know it predates this branch. Deliberately not + reformatted — out of scope. +- **The `request.ts` reachability guard is a regression test, not a proof.** It hand-rolls a static + import walk covering `import/export … from`, bare `import "x"`, and `import("literal")` — but not + `require()`, re-export through a variable, or a computed dynamic specifier. It fails correctly when + someone adds a normal import (verified), and the dead-code conclusion rests on all three lines of + evidence together rather than on this test alone. It also asserts `reachable.size > 400` as an + anti-vacuity floor (today: 594), so a refactor that legitimately shrinks the graph would fail it + spuriously — a one-line fix if that happens. +- **The ModelsDev collision test injects via `spyOn(ModelsDev, "get")`**, so it does not exercise the + real `models.json` fetch/parse path. The injection point is documented in the test. + +**Findings that mattered most, in rough order:** + +| Finding | Why it mattered | +|---|---| +| LiteLLM's `internal_user` role includes `/key/*` | A free-tier key could mint itself unlimited keys through its own inference port. Fixed with `internal_user_viewer`; key-level `allowed_routes` does *not* help, as it is only consulted in a later `elif`. | +| 37 real over-privileged principals | The migration found them on our own stack, 36 predating this work. "Self-healing on re-registration" only repairs a *cooperative* principal; an attacker never comes back. | +| `async_logging_hook` never fires on failures | Any forced error shipped raw prompts to Langfuse with no redaction at all. | +| Secrets in `tools[].function.description` | Reached Langfuse raw, because tools ride in `optional_params`, not `messages` — confirmed by canary before fixing. | +| Migration offset paging over unstable ordering | `/user/list` sorts by nothing unless asked, so rows shift between pages and displaced ones are never seen — then it reports success. The exact silent-partial failure of the snippet it replaced. | +| Atomic write without a shared lock | Made a partial-corruption bug *worse*: the last rename now deletes the other writer's credential outright (reproduced 40/40). | +| `AuthService` narrowed the credential schema | Adding or removing any other provider silently dropped our `install_secret` and `base_url`. Surfaced only when the two `Auth` implementations were put side by side. | + +**Two claims corrected by measurement**, both of which I had relayed as fact: a ~60s role-propagation +cache window (measured 0s in our configuration) and a budget-reset postponement (this version uses +calendar-aligned resets — verified across three consecutive registrations). + +**Stopped without a clean verdict.** The final gateway review was terminated by a provider-side +content refusal after ~50 minutes, and an earlier attempt was killed mid-run, so one round-3 finding +was never identified. That is an absence of a verdict, not evidence of safety, and it should be read +that way. + +## Follow-ups discovered during the build (tracked separately, none blocking) + +1. **`run` hangs silently when the first turn errors.** Reproduced on clean `main` with + google-vertex and no credentials: no output, never exits, no error rendered (exit 124, 96 bytes). + Pre-existing and provider-agnostic. It matters here because a no-signup free tier makes + first-turn errors easy to hit (budget exhausted, rate limited, registration failed), so a user's + first experience of a failure is a hang. Own change, own tests. +2. **Capture the real `budget_exceeded` body.** The 429 work proved the value: live bodies + contradicted our tests three ways (no `Retry-After` at all, two sub-flavours of + `throttling_error`, and the gateway naming the key identifier in its own message).
