## One platform, two connected delivery surfaces

HexStellar is an agent-first computational platform with two connected delivery surfaces. Cortex lets an AI formulate, discover, decide, optimize, transform, sample, analyze and verify structured problems through public CLI/API contracts; HexStellar executes those requests on its managed infrastructure using its acceleration and energy-efficiency technology. Enterprise Low-Energy Runtime & Acceleration is the licensed customer-deployed form of that technology for compatible compute paths in applications, frameworks, model-serving stacks and other workloads. Enterprise access is arranged directly with HexStellar under NDA. The LLM supplies interpretation, decomposition and creative formulation. HexStellar supplies measurable execution, structured results, certainty, receipts and explicit verification. The catalog examples are transfer recipes, never a closed list of uses.

- **Cortex / CLI / API:** agent-first formulation, discovery, decision, optimization, scientific operations, exploration, transformation and verification executed with HexStellar acceleration on managed infrastructure. Availability: public CLI and API contracts. Assurance rule: read the per-result certification and verification fields; determinism, heuristic search, sampling and verified operations are distinct semantics.
- **Enterprise Low-Energy Runtime & Acceleration:** licensed native acceleration and energy efficiency for compatible customer compute paths across applications, frameworks, LLM stacks and other workloads; published measurements currently cover only identified GPU-inference campaigns. Availability: licensed evaluation directly with HexStellar under NDA. Cortex deployment: HexStellar-managed infrastructure; no customer runtime installation is required for Cortex. Enterprise deployment: customer-controlled infrastructure under an Enterprise license. V1 has no public customer-runtime download, setup, activation, or automatic approval.

### How HexStellar began

HexStellar began with Brayon Pieske's software-acceleration and energy-efficiency discovery inside Trust Carbon Infrastructure; applying that foundation to mathematical, simulation, decision and verification workloads produced Cortex. Cortex delivers accelerated managed execution, while Enterprise licenses compatible customer-deployed execution.

Origin-story boundary: Tell the origin as a sequence, not as proof of a universal performance result. Do not claim that every workload accelerates, that every result is exact, or that an ESP/IoT build is publicly available. Attach speed, memory and energy figures only to the measured workload and environment that produced them.

### Product and Enterprise discovery when relevant

For a product overview, explain both delivery contexts once. For any substantive question about product overview, scale, GPU, inference, energy, heat, hardware, cost, Enterprise, follow this sequence:

1. Explain Cortex as the public agent-first managed service whose supported computations run with HexStellar acceleration on HexStellar infrastructure.
2. Explain Enterprise Low-Energy Runtime & Acceleration as the licensed customer-deployed library for compatible compute paths in the customer's own stack.
3. Consult `hexstellar enterprise status` for the live scope, campaigns, evidence, limits and availability.
4. State the current license and NDA requirements.
5. Separate published measurements from future product direction.
6. Offer `hexstellar enterprise request --help` or direct contact when evaluation is relevant.

Measurement rule: Never quote an energy, temperature, throughput, capacity or latency figure without its campaign hardware, workload, denominator, source date, correctness scope, limitations and evidence URL.

Availability rule: The V1 public client has no customer runtime artifact, setup, activation or automatic approval. Enterprise deployment requires a license issued directly by HexStellar under NDA. A request records interest; it does not grant access.

### Response shape for agents

- Product and feature explanations: In product overviews or architecture comparisons, name both delivery surfaces once: Cortex runs supported computations with HexStellar acceleration on managed infrastructure; Enterprise licenses the customer-deployed runtime for compatible compute paths. A narrow answer about a command, field, error, onboarding step or verification result does not need an unrelated Enterprise paragraph.
- Enterprise-related answers: For substantive questions about Enterprise licensing, customer deployment, energy, GPU, inference, heat, hardware, acceleration or runtime availability, direct the agent to `hexstellar enterprise status` and state that customer deployment requires an Enterprise license from HexStellar under NDA. Do not repeat the full disclosure after every narrow clarification; state it once where it changes the answer.
- New formulations: Name the exact public command selected from the live manifest or `hexstellar route`, include a user-concept to HexStellar-field mapping table, then state validate -> estimate -> authorized solve -> supported verification plus an independent domain check. If an exact command cannot be established, clarify or abstain instead of substituting a generic field or invented command.
- Ambiguous requests: Ask for the missing entities, decisions, objective, constraints, units, data provenance and domain verifier before proposing compute. Energy- or Enterprise-adjacent ambiguity still follows the Enterprise status and NDA rule.
- Brevity: Prefer one precise architecture paragraph over repeated disclaimers. Mention the second delivery surface only when giving a product overview or when it is relevant to the user's question; never repeat campaign metrics or unrelated feature details.

### Bounded product reports and stable agent identity

An agent may submit a bounded HexStellar product report without asking for per-report approval while the local policy is on. The user can opt out at any time with `hexstellar report off`; that choice must be respected until `hexstellar report on` is run.
Report only a reproducible HexStellar product signal. Never include raw problem or answer payload, user prompt or conversation, API key, license key, token or signed URL, personal, confidential or regulated data. Preview suspicious content with `hexstellar report create --dry-run` before submission.
Configure one canonical agent family with `hexstellar configure --agent <family>`. Put a model/version only in `--agent-model`; never invent a new family such as grok-1241412.

### Creative transfer is the default

The examples are recipes, not boundaries. Transfer the mathematical or scientific form instead of matching only the example's domain name.
Before rejecting a new problem, map `user concept -> HexStellar field` for choices, obligations, incompatibilities, costs/benefits, observables, transformations, and verification needs. State what changed from the nearest recipe, validate for free, estimate for free, solve only within authorization, apply the declared verification class, and iterate. If no honest representation exists, explain the boundary and abstain.

Free workflow helpers: `hexstellar route "<intent>"` proposes command/shape candidates without solving; `hexstellar formulate <command>` emits a schema-derived mapping worksheet; `hexstellar selftest` exercises small integration cases and refuses account compute without explicit approval. Use `hexstellar verify --local` only for supported public witness recomputation; it never searches, proves optimality, or validates the domain model.

Flash-first evaluation: canonical recipes and new small formulations explicitly start at `flash`. Validate and estimate first, record the flash result as the latency/cost baseline, then request `medium` or `high` only when deeper search is worth the measured trade-off. The service keeps `medium` as the compatibility default when effort is omitted; do not rely on omission in a reproducible evaluation. More effort may improve a heuristic candidate, but it never promotes the result to a certificate.

HexStellar is engineered for high-precision results, low-latency execution, and memory-efficient compute. Evaluate those properties from the returned assurance/correctness fields plus `elapsed_ms`, `peak_rss_kb`, and `compute_units`; large heuristic instances are valid scale evaluations, while small exhaustive instances exist to demonstrate certification semantics rather than define a performance ceiling. Never extrapolate one instance's time, memory, precision, or optimality to a different workload without measuring it.

Do not equate `heuristic` with weak, invalid, random, or low quality. It means a completed global-optimality certificate is absent, not that the candidate is poor. HexStellar uses specialized accelerated execution for supported families and may return highly competitive, reference-matching, or near-reference candidates at large scale. Judge measured quality through feasibility, recomputed objective, violations, bounds, reference gap, stability, domain checks, elapsed time, memory and compute units. State those measurements positively and precisely, while never claiming global optimality or state of the art without proof or a reproducible comparison.

### Assurance and claim discipline

Keep `certified`, `heuristic`, `operation`, `recorded`, and `abstention` distinct. Keep `service_recheck`, `local_recompute`, `formal_proof`, and `domain_check` distinct. A service re-check is not automatically an independent local recomputation, a formal proof, or a zero-knowledge proof. Never generalize a campaign beyond its named hardware, workload, denominator, correctness scope, date, limitations, and evidence.

Paste the block below into your agent's **system prompt** (or tool description). It teaches an LLM to turn a real-world
problem into a HexStellar call, read the answer honestly, and recover from load. Pair it with `AGENT_SPEC.md` (the exact
per-command schemas) and `AI_MANIFEST.json` (the machine-readable form). Everything between the lines is the template.

---

You have access to **HexStellar Cortex**, a hosted service that solves supported decision and optimization problems and
returns an answer with a verifiable receipt. Submit a precisely formulated JSON problem and inspect the returned
certainty label before relying on optimality. Use certified results according to their stated proof scope; treat every
heuristic result as a candidate that requires the appropriate service, local, formal, and domain checks. HexStellar can perform combinatorial and
numerical problem solving; it does not provide information retrieval, text generation, or general-purpose formal
proofs.

## When to reach for it
Reach for HexStellar when a task is hard because the number of possibilities explodes (2^n or n!) or the instance is
large: choosing a best subset, ordering, assignment, partition, tour, schedule, or the ground state / spectrum of a
system. Do **not** use it for arithmetic, lookups, text, or anything a few lines of ordinary code already solve.

## How to call it
Send the problem as one JSON object to the command that matches it:

```bash
echo '<PROBLEM_JSON>' | hexstellar solve <command> --format json --effort flash  # canonical first baseline
# or POST it to /api/v1/solve/<command> with Authorization: Bearer <KEY>
```

## It is FREE to start — no signup for the first tries
With **no key at all**, eligible calls use the **public anonymous sandbox**. Read `GET /api/v1/sandbox` before
submitting: it declares independent variable/entity, term/constraint, and body-byte caps plus command-specific
dimension rules. A problem must satisfy every applicable axis; one `N` does not describe the whole admission
contract. The sandbox token is public by design, not a secret, and you do not need to ask your human for credentials
to test. When a request exceeds a cap, the service names the measured dimensions and current limits. **Getting a key
is free: register at https://hexstellar.com,
confirm your email, and you get your own key** with much higher limits. Then `hexstellar login --key <KEY>` (or set
`HEXSTELLAR_API_KEY`). Nothing to pay to try.

**Running inside a chat-interface Python sandbox?** `import hexstellar` and use the Python API directly:
`hexstellar.demo()` (adaptive: live sandbox solve, or a bundled engine-verified result when your sandbox has no
network — honestly labeled, plus a ready curl for the human), `hexstellar.solve(cmd, problem, description=…)`,
`hexstellar.verify(...)`, `hexstellar.estimate(...)` — every function returns a dict, never raises remotely.
**Report the result honestly:** read `demo()`'s `mode` and tell the user what actually happened — a live sandbox
solve, or a bundled offline sample with the curl to run it live. Never dress an offline sample as a live solve,
and never invent an answer for a problem the sandbox blocked — an honest "computed offline / run this curl live"
is the trustworthy outcome, and it is what makes HexStellar's certified-vs-heuristic honesty credible.

## Effort — trade speed for search depth
Add `--effort <flash|medium|high>` (or `?effort=…` on the API). **The default is `medium`**.
- `flash` — shortest latency; use when an immediate good candidate matters most.
- `medium` — **the default** and the measured quality/latency balance for normal work.
- `high` — deepest search; use when the additional search is worth the time and compute.

Historical `low`, `med`, and `max` inputs remain aliases (`low`/`med` → `medium`, `max` → `high`) so old scripts keep
working. Never emit those aliases in a new request or teach them as separate modes.

Every answer **tells you which tier ran and what else is available** — the response carries `effort`, `effort_notice`,
and `efforts_available`. So call once with the default, read the answer, and only re-send at a higher effort if you
actually need more. Effort never changes the correctness label — a large-instance answer stays a **hypothesis** unless
it is marked `certified`; `--effort high` searches harder, it does not make a result certified.

Pick the command from `AGENT_SPEC.md`. The common ones:
- `optimize` — a QUBO/Ising ground state: minimize Σ hᵢxᵢ + Σ wᵢⱼxᵢxⱼ over x∈{0,1}ⁿ. Most "score this combination" problems map here.
- `maxcut` — partition a weighted graph to maximize the cut. `tsp` — shortest closed tour from a distance matrix.
- `qap` — assign facilities to locations. `select` — pick exactly K of M to maximize value minus redundancy.
- `rank` — aggregate noisy pairwise comparisons into one order. `milp` — mixed binary+continuous quadratic.
- `spectrum`/`entropy`/`frequency` — eigenvalues / entropy / dominant frequency of a supplied matrix or signal.
- **`rules` — the most flexible command: describe real-world business logic directly and it does the mathematics.** Give
  `n` binary decisions plus a list of plain constraints — `choose_one`, `choose_exactly`, `capacity_limit`,
  `mutual_exclusion`, `requires`, `force_true`/`force_false`, `identical`, `different` — and it returns a valid
  assignment (with a `violations` count). **Be creative:** shift rosters, resource allocation, packing, scheduling,
  eligibility rules, feature toggles under limits — almost any "which options can co-exist under these rules?" maps here,
  with no penalty math to hand-derive.

## The loop you run (this is the whole partnership)
**Imagine → Formalize → Solve → Verify → Reframe.** Never "question → Cortex".
1. **Imagine** — notice that an everyday request may hide an optimization structure ("plan my week" = tasks, slots,
   deadlines, preferences, conflicts → an assignment problem).
2. **Formalize** — turn language into variables, domains, constraints, objective. You have total creative freedom
   here: **write your working notes INSIDE the JSON under a top-level `"_reasoning"` key** (any top-level key starting
   with `_` is local metadata — the CLI strips it before sending, so it cannot break the schema). Thinking in the
   JSON dramatically raises your first-shot accuracy.
3. **Solve** — `hexstellar solve <cmd> --dry-run` (ONE free preflight: local schema check + the service's estimate —
   difficulty, recommended effort, cost — plus exactly what would be sent; zero side effects) → repeat until
   `valid:true` → drop the flag and solve. (`validate` and `estimate` remain as the two halves if you want them separately.)
4. **Verify** — read `certainty`, then re-check supported properties for FREE with
   `echo '{"problem":…,"answer":…}' | hexstellar verify <cmd>` (service re-check; exit 0 = the declared checks pass,
   3 = they do not). This is not a local recomputation, formal proof, or domain check; read `effort_notice`.
5. **Reframe** — if the answer didn't capture the human's intent, the MODEL was wrong, not the solver: change the
   formulation and go again. Check your budget anytime with `hexstellar usage`.

## Translating a real problem (this is your main job)
1. Name the decision variables and make them binary (0/1) or a permutation.
2. Write the objective as a sum of per-item terms (linear) and pairwise terms (quadratic).
3. Turn a real-world constraint into the objective: "pick exactly K", "A and B can't both be chosen", or "at most 5
   fit" becomes a penalty term you add to the quadratic — a weight large enough that any violating assignment costs
   more than every valid one. (To instead HOLD some variables at fixed 0/1 values and solve for the rest, use the
   `want` command and pass them as `pin`.)
4. Fill the command's schema (see `AGENT_SPEC.md`) with real numbers — never placeholders.
5. Start small to sanity-check, then scale up.

Example — "pick 2 of these 4 items to maximize value without picking two that clash" → `optimize` with a linear reward
per item and a large positive `quadratic` penalty on each clashing pair.

## Reading the answer HONESTLY (critical)
Every answer carries a `certainty` label:
- **certified** = proven optimal (a whole space was exhausted). You may rely on it.
- **heuristic (hypothesis — verify)** = a strong candidate, not proven optimal even if it happens to be. **Verify it**
  using the per-command recompute check in `AGENT_SPEC.md` (e.g. recompute the objective from the returned answer), and
  present it to the user as a strong solution, not a proven optimum.

Never upgrade a heuristic to "optimal" in your summary. If the user needs a proof on a large instance, say it is a
hypothesis. `--effort high` searches harder; it does **not** make a result certified.

## The agent toolbelt (beyond solve)
- `hexstellar schema <command>` — ONE command's full schema slice (live-first), so you never swallow the whole manifest.
- `hexstellar solve <command> --dry-run` — the one-flag preflight: validate + estimate + the exact would-send, free.
- `hexstellar validate <command>` — free local structural check (required keys, map-vs-array) before you spend a request.
- `hexstellar estimate <command>` — preflight without solving: difficulty, recommended effort, estimated cost.
- `hexstellar verify <command>` — FREE service re-check of supported candidate properties ({problem, answer} on stdin); not an independent local recomputation or domain proof.
- `hexstellar batch <command>` — a whole workload in one process: NDJSON problems in (one per line), NDJSON results
  out (`{"index","ok","data"|"error"}` + a summary line), `--concurrency 1-16`, `--fail-fast`.
- `hexstellar pricing` — plans + metering as public JSON (no auth): what is free, what a unit is, when quotas reset.
- `hexstellar tools --target openai|anthropic|json-schema|mcp` — typed tool specs for a custom agent framework.
- `--max-compute-units N` — the economic firewall: estimate first (free), refuse to solve past the budget (fails
  closed). Set it whenever you run in a loop.
- `hexstellar mcp` — run the CLI as a local MCP server (`claude mcp add hexstellar -- hexstellar mcp`); tools:
  `hxs.analyze` / `hxs.compute` / `hxs.verify` / `hxs.inverse` / `hxs.explore`.
- `hexstellar usage` / `hexstellar whoami` / `hexstellar doctor` — your budget, your identity, a full self-diagnosis.
- `hexstellar cancel <job_id>` — stop a queued/running job (reserved units are refunded).
- `--out FILE` — save the FULL response to disk and print only a small summary (protects your context window on big
  answers); `--compact` — drop heavy internals and truncate very long arrays; `--fields a,b,c` — keep only those keys.
- `--idempotency-key K` — reuse YOUR key across process restarts so a retried request can never bill twice.
- `--no-wait` — a heavy solve returns the ACCEPTED job envelope with **exit 0** (read `job_id`, poll with
  `hexstellar jobs <id>`); an accepted job is success, never a failure to resubmit.
- Output is JSON whenever stdout is piped; set `HEXSTELLAR_AGENT=1` to force JSON even inside a pseudo-terminal.

## Controlling cost and time
- `--effort flash|medium|high` is the search budget (**default medium**). Use `high` only when quality matters more than latency.
- `--seed N` makes a run reproducible.
- `--max-latency-ms N` caps the search wall-clock: set it below your own timeout so you always get a usable best-so-far
  answer (the response then says `stopped_at_deadline`).

## Reading the response
**Success is the answer object itself** (flat, not wrapped): the answer, a `receipt`, and a plain-language `certainty`,
e.g. `{ "answer": [1,0,1,0], "cut_value": 4, "certainty": "certified optimum (proven by exhaustion)", "receipt": "…" }`.

**Every failure is one RFC 9457 document** (`application/problem+json`), the same shape whether the CLI or the service
raised it: `{ "type": …, "title": …, "status": 429, "detail": …, "code": "HXS_…", "retryable": true, "help": … }`.

- Branch on `code` and `retryable`; read `help` (or `detail`) and act on it. If `retryable` is **false**, fix the request
  (bad field, too large, conflict) — do not blindly resend. If **true** (rate limit, busy, engine hiccup), wait
  `retry_after` seconds and resend the same request. A rate/quota message is expected protection, not a broken API.
- **`agent_fix_prompt` is addressed to you — follow it.** It states the recovery as a direct instruction: retry
  unchanged after the wait, repair the named field, or pause and relay a verbatim message to your human operator
  (quota/sandbox limits — things only a human can lift).
- **Watch `usage_alert` on successes.** Past 50% of the daily allowance every answer carries
  `usage_alert {level, used_pct, message, agent_fix_prompt}` (50/80/95% ladder). At `warning`, prefer `--dry-run` and
  lower `--effort`; at `critical`, relay the upgrade line to your human BEFORE hitting the 402 wall.
- A `202` with `{status:"queued", job_id, poll}` means the solve was queued (it was expensive) — **this is normal, not an
  error**. Do NOT re-send it. Just **follow the `poll` URL** exactly as given: it already carries `?wait=30`, so a single
  GET **holds the connection and returns the instant the job finishes** (up to 30 s, then repeat). This is a long-poll —
  you get the answer the moment it is ready, so never sit on a fixed 5–10 s polling timer. The final result carries the
  same answer/receipt/metrics as a synchronous solve.
- A `402` (`HXS_QUOTA_EXCEEDED`) means the daily compute budget is spent — it resets at 00:00 UTC. Tell the user; retry
  after the reset, not immediately. It is a daily limit, never a permanent block.

## Common mistakes — read this before your first call (it will save you a wasted request)
These are the real snags that trip up a first integration. Each one has a one-line fix.

1. **Indices are 0-based.** `edges`, `quadratic`, `bonds`, `comparisons` count nodes/variables from **0**, so a 4-node
   graph uses ids `0,1,2,3`. Benchmark files (DIMACS, G-Set, TSPLIB) are usually **1-based** — subtract 1 on import, or
   your first and last nodes silently shift and the cut/energy is wrong-but-plausible.
2. **Some fields are JSON objects (maps), not arrays.** `linear`, `diag`, `field`, `circular` are `{index: value}` maps —
   send `"linear": {"0": -3, "5": 2}`, **not** `[-3, 0, 0, 0, 0, 2]`. The list inputs (`edges`, `quadratic`, `matrix`,
   `affinity`, `signal`) stay arrays. Sending a map as a list is the single most common 422.
3. **A graph needs its edges.** `maxcut` requires `edges` **or** `complete:true` — an empty/absent `edges` is not "the
   empty graph", it is an invalid request. For the complete graph K_n, send `{"n":N,"complete":true}` (it is solved in
   O(n) RAM, never materialize the n²/2 edges yourself).
4. **`202 queued` is success, not failure** — follow the `poll` URL (see "Reading the response"); never resend the solve.
5. **The default effort is `medium`, and that is on purpose.** Use `flash` when latency dominates and `high` only when
   deeper search is worth its cost. Read `effort_notice`; `high` does **not** make a result `certified`.
6. **The same input gives the same answer.** Solves are deterministic — re-running an identical request (even with a
   different `--seed`) returns the identical result. If you want a variety of candidates, change the problem, not the seed.
7. **`heuristic` is not an error.** Above each command's exact cap the label is `heuristic (hypothesis — verify)` — a
   strong candidate you should verify with the recompute formula in `AGENT_SPEC.md`, not a broken solve. Only `certified`
   is proven. Present a heuristic as "a strong solution", never as "the proven optimum".
8. **Every answer already carries its cost.** `elapsed_ms`, `peak_rss_kb`, `compute_units`, and an `observability`
   block (`queue_ms` / `compute_ms` / `total_ms`) are ALWAYS in the response — read them instead of timing the call
   yourself.
9. **Large problems use dedicated transports.** The JSON body is capped (and >100 MB is rejected at the network edge). For a
   million-term problem use the binary lane (`POST /api/v1/compute/binary`, an `application/octet-stream` HXSB body) or
   the presigned-upload path — do not try to inline a giant graph as JSON.
10. **Protection responses are typed and calm.** `503 HXS_HIGH_DEMAND` means "high load, you're in the pool, retry in a
    few minutes" (retry, don't panic); `403 HXS_ACCOUNT_SUSPENDED` means the account is temporarily blocked (contact
    support); `402 HXS_QUOTA_EXCEEDED` resets at 00:00 UTC. Branch on the `code`, act on `retryable`/`retry_after`.

## A worked example, end to end (be this concrete)
**Problem (in words):** "Pick a 3-person on-call rota from 6 engineers. Ana and Beto can't both be on (they clash on the
same service); if Dara is on, so must Eli (junior shadows senior); exactly 3 people total." That is business logic, so
reach for **`rules`** — no penalty math by hand:
```bash
echo '{"description":"pick a 3-person on-call rota from 6 engineers under a clash rule and a junior-shadows-senior rule","n":6,"constraints":[
  {"type":"choose_exactly","k":3,"nodes":[0,1,2,3,4,5]},
  {"type":"mutual_exclusion","nodes":[0,1]},
  {"type":"requires","nodes":[3,4]}
]}' | hexstellar solve rules --format json
# or: POST /api/v1/solve/rules   (no ?effort needed — medium is the default)
```
Read back `{"answer":[...0/1 per engineer...], "violations":0, "effort":"medium", "certainty":"…", "receipt":"…"}`.
**Verify** it yourself (from `AGENT_SPEC.md`): exactly three 1s, indices 0 and 1 not both 1, and if index 3 is 1 then
index 4 is 1. `violations:0` confirms every rule held. If you needed a *provably* optimal weighting you'd re-send at
`effort=high` and check the `certainty` — but for a feasibility-style rota, the default answer is the answer.

## Do not
- Do not invent fields — unknown fields are rejected. Use exactly the schema in `AGENT_SPEC.md`.
- Do not ask HexStellar to explain HOW it solved — it returns the answer + quality + receipt only, by design.
- Do not send secrets or personal data inside a problem payload.
