chore(sync): mirror backend .py + Dockerfile to Space (hf-sync-backend)

Automated backend sync from szl-holdings/a11oy main via hf-sync-backend.
Updated (differed from the Space): Dockerfile, a11oy_harvest_endpoints.py, revenue_endpoints.py, szl_energy_budget.py, szl_energy_provenance.py, szl_engine_status.py, szl_heart_blood.py
Deleted (gone from the repo + Dockerfile COPY set): (none)

Keeps the Space-built backend (serve.py + the Dockerfile-COPY'd .py
modules) identical to GitHub main so the Space never rebuilds from a
stale backend, new endpoints don't 404 there, and orphaned modules
removed from the repo don't linger in the Space tree.

+"""a11oy_harvest_endpoints.py — live HTTP surface for wasted-energy harvest posture.
+
+Doctrine (binding):
+  - NO free-energy / over-unity. Harvests ALREADY-WASTED grid energy (negative-price /
+    curtailed-renewable windows on PUBLIC free feeds). Does NOT create energy.
+  - joules_label ALWAYS "sample" off-box. The API NEVER emits joules_label other than
+    "sample". The box is the only place that flips it to "measured" (on-box NVML).
+    This API does NOT run on the box.
+  - All feeds are FREE and PUBLIC — no token, no key, open data.
+  - Reactive turns are NEVER gated by harvest posture.
+  - Λ = Conjecture 1 (NEVER a theorem). Locked-8 untouched.
+  - Real data only. NO MOCKS — if a feed is down, reachable:false reported honestly.
+
+Free feeds (live, probed 2026-06-13, all responded):
+  - aWATTar DE/AT wholesale price (api.awattar.de|at) — negative price = wasted
+  - Energy-Charts / Fraunhofer (api.energy-charts.info) — renewable share + grid frequency
+  - UK Carbon Intensity (api.carbonintensity.org.uk) — low-carbon surplus index
+  - Open-Meteo (api.open-meteo.com) — wind/solar forecast = future surplus outlook
+  - CAISO OASIS (oasis.caiso.com) — US California public LMP reachability probe
+
+Formula citations (Lean kernel-proven, 0-sorry):
+  - Bekenstein additive cap: bekensteinBits, bekenstein_bound_additive, info_within_bound
+    [EnergyBudgetWitness.lean, lutar-lean PR #239, 0-sorry]
+  - Landauer floor: landauer_floor_pos, energyFloor [LandauerFloorWitness.lean, PR #240]

+revenue_endpoints.py — SZL Holdings honest revenue ESTIMATE endpoints.
+
+Registers /api/a11oy/v1/revenue/* endpoints into the a11oy FastAPI app.
+Pattern: same try/except-guarded register(app, ns="a11oy") as other a11oy modules.
+Pure stdlib (+ revenue_model.py, also pure stdlib). No keys committed. Additive only.
+
+Doctrine (binding — revenue figures demand maximum honesty):
+  - Every response is explicitly labeled ESTIMATE or PRICING_HYPOTHESIS.
+  - Numbers are computed from REAL inputs (live grid prices via aWATTar,
+    real VIIRS satellite flare volumes). Never fabricated.
+  - If live feeds are unreachable, uses documented sample values — labeled as such.
+  - No free-energy. Joules stay SAMPLE until on-box NVML.
+  - Λ = Conjecture 1. Locked-8 untouched. No key.
+
+Endpoints:
+  GET /api/{ns}/v1/revenue/estimate
+    Pulls LIVE harvest posture + flared-gas leaderboard, runs all four estimators,
+    returns structured honest revenue ESTIMATE breakdown.
+
+  GET /api/{ns}/v1/revenue/thesis
+    Static honest summary: business model, real market comparables
+    (Crusoe $3B, $16B flare, $8–15M/100MW DR), SZL's differentiator.

+szl_energy_budget.py — SHARED energy-budget receipt layer for a11oy (Proven Energy Engine).
+
+Per compute task, records a Bekenstein-GATED receipt binding the task's information
+content (Shannon) to its physical information-capacity bound (Bekenstein, N·8 bits)
+and its energy draw (joules) — so every harvested joule and compute cycle carries a
+verifiable, bounded receipt. This is the runtime companion to the kernel-proven Lean
+formulas (F19 Bekenstein additivity + TH6 DPI bound; F12 Kuramoto; coherence-decay).

+  output_bytes         n output bytes the task produced
+  shannon_bits         Shannon information content of the output (bits)
+  bekenstein_bound_bits  N·8 — the SZL canonical Bekenstein software bound (TH6)
+  within_bound         shannon_bits <= bekenstein_bound_bits  (the F19/TH6 gate)
+  energy_source        harvest source label (default "grid")

+  ts                   ISO-8601 UTC timestamp
+
+DOCTRINE (v11/v12, NEVER violated):
+  - NO free-energy / perpetual-motion claims. We harvest WASTED energy and PROVE
+    bounded work; the Bekenstein gate proves the joules bought real, bounded info work.
+  - Every energy number (joules_est) is LABELED "SAMPLE/ESTIMATE" until a real power
+    meter is wired. The endpoint reports honestly; the half-state (claiming more energy
+    than is real) is the only unacceptable outcome.
+  - open-weight only; never commit a key.

+  shannon_entropy_bits(probs) = -Σ p·log2(p)         (Shannon, bits per symbol)
+Because a byte's empirical entropy per symbol is in [0, 8], the total Shannon content

+szl_energy_provenance.py — tamper-evident PROVENANCE CHAIN for a11oy energy receipts.
+
+The "honest AI on honest power, with receipts" proof layer. It extends/complements
+szl_energy_budget.py (#328): where the budget module produces a Bekenstein-GATED
+receipt per compute task, this module binds those receipts into a verifiable,
+append-only, hash-linked ledger (a mini Merkle/Rekor-style transparency log) so the
+whole energy history is tamper-evident and offline-verifiable — matching SZL's
+cosign + Rekor + in-toto receipt doctrine.
+
+  GET  /api/<ns>/v1/energy/provenance   -> chain head + length + verify() status
+
+Each chain entry records (and hash-binds):
+  prev_hash        receipt_hash of the immediately prior entry ("" for genesis)
+  receipt_hash     sha256 over the canonical bytes of THIS entry's content
+  task_hash        stable id of the task inputs (from szl_energy_budget.task_hash)
+  bytes            output bytes the task produced (n)
+  shannon_bits     Shannon information content of the output (bits)
+  bekenstein_bound N·8 — the SZL canonical Bekenstein software bound (TH6/F19)
+  within_bound     shannon_bits <= bekenstein_bound (the F19/TH6 gate)
+  energy_source    harvest source label (e.g. curtailed-solar, off-peak, grid)
+  joules_est       SAMPLE/ESTIMATE energy draw — NOT a metered value
+  ts               ISO-8601 UTC timestamp
+
+verify() walks the chain and confirms BOTH:
+  (1) link integrity — each entry's prev_hash equals the prior entry's receipt_hash,
+      and each entry's recomputed content hash equals its recorded receipt_hash
+      (so any tampering of any field, or any reordering/insertion/deletion, is caught);
+  (2) the Bekenstein gate — every entry has within_bound is True.
+
+DOCTRINE (v11/v12, NEVER violated):
+  - NO free-energy / perpetual-motion claims. The chain proves WHAT was receipted and
+    that it is UNTAMPERED + Bekenstein-bounded — it does NOT upgrade an estimate into a
+    measurement. Every joules_est stays labeled SAMPLE/ESTIMATE until a real meter.
+  - Tamper-EVIDENT, not tamper-proof: it proves the recorded history is internally
+    consistent and gate-passing; it makes NO "measured energy" claim.
+  - open-weight only; never commit a key. Pure stdlib; no numpy, no network.
+
+Reuses the canonical Bekenstein/Shannon math from szl_energy_budget when that module
+is importable (#328); otherwise carries a byte-identical local fallback so this module
+runs and self-tests standalone (the PR depends on #328 but does not require it merged).

+szl_engine_status — the UNIFIED STATUS API for the agentic-GPU organism.
+
+ONE read-only endpoint, GET /api/a11oy/v1/engine/status, aggregates the WHOLE
+living body into a single honest JSON the 3D hologram (F1) and every dashboard
+read from:
+
+    {
+      mind:    {sovereign, posture, inference, gpu, base_url}   # from /code/healthz
+      organs:  {brain, heart, blood, immune, skeleton, nervous} # each {reachable, status}
+      energy:  {window, source, joules{value,label}, within_bound}   # from the budget
+      swarm:   {nodes, served_by}                               # if available
+      doctrine:{lambda:"Conjecture 1", locked:8, half_state:"forbidden"}
+    }
+
+HONESTY (Doctrine v11/v12), enforced by construction:
+  - NEVER fabricate a status. Every sub-probe runs with a timeout and degrades to
+    {"reachable": false, "status": "unreachable", "error": ...}. A missing organ
+    is reported as down — never bluffed green.
+  - sovereign:true ONLY when /code/healthz says so. If the MIND probe fails or is
+    silent, sovereign is false. We never infer sovereignty from any other signal.
+  - joules carry an explicit label: "measured" ONLY when the budget feed reports a
+    real metered figure; otherwise "sample"/"estimate". No greenwashing.
+  - Λ = Conjecture 1 is stated in the payload (the skeleton's killer formula is
+    intentionally a conjecture — we say so); locked-8 untouched; half_state forbidden.
+  - No key, open-weight, pure-stdlib aggregation. The probes are read-only GETs.
+
+The endpoint is additive and try/except-guarded in serve.py, registered BEFORE the
+SPA catch-all. If httpx/FastAPI are absent at import time the module still parses
+and the self-test (which injects a fake fetcher) runs on pure stdlib.

+szl_heart_blood.py — the HEART+BLOOD receipt heartbeat for the agentic GPU.
+
+This formalizes the live "receipt heartbeat" of the anatomy shell: every GPU /
+energy action is a measurable BEAT on a σ-algebra receipt bus (HEART), and BLOOD
+signs + carries that beat as a DSSE-style, hash-linked, OFFLINE-verifiable envelope.
+It WRAPS — never replaces — the existing energy provenance chain (#331): each chain
+entry is consumed as a beat, so the provenance chain literally IS the heartbeat.
+
+  GET /api/<ns>/v1/heart/pulse  -> latest beats + a verify() result
+                                   (all beats hash-link-verified + tamper-checked)
+
+PROVEN BACKING (lutar-lean round9, kernel):
+  - HEART  = HeartReceiptSigma : the receipt bus is a σ-algebra over the sample space
+             of GPU/energy events. The bus demonstrates the σ-algebra closure axioms:
+               (1) the whole space Ω and the empty set ∅ are members,
+               (2) closed under complement  (Aᶜ = Ω \\ A),
+               (3) closed under countable (here: finite) union  (⋃ᵢ Aᵢ),
+             and therefore (de Morgan) under intersection. Each "beat" is a measurable
+             event = a singleton beat-set; composing beats by ∪ / ∩ / complement stays
+             in the algebra, so the receipt bus is closed under event composition.
+  - BLOOD  = BloodDSSEMerkle : a DSSE envelope (payload, payloadType, signatures over
+             PAE) whose payloads are linked into a hash-linked Merkle chain over beats.
+             A flipped byte anywhere breaks PAE → digest mismatch → verify() FAILS.
+
+LIVE HEART/BLOOD ENDPOINTS this mirrors (read-only, real):
+  HEART : amaru  /api/amaru/receipts        + sentra /api/sentra/khipu/ledger
+  BLOOD : sentra /api/sentra/khipu/sign
+
+DOCTRINE (v11/v12 — NEVER violated):
+  - NO real signing key is committed. Signing here is a DOCUMENTED PLACEHOLDER:
+    a local digest = HMAC/SHA-256 over the DSSE PAE, keyed by a clearly-labeled
+    SAMPLE string. Every spot where a real cosign / Cardano cosign key would go is
+    marked SAMPLE with a comment. The result is TAMPER-EVIDENT (a flipped byte breaks
+    verification) — it is NOT claimed to be cryptographically "signed" / "measured" /
+    "notarized". Label stays SAMPLE / tamper-evident.
+  - joules / energy figures are SAMPLE/ESTIMATE until metered. open-weight only.
+  - Λ stays Conjecture 1. Pure stdlib (hashlib, hmac, json); no network in self-test.
+
+This file is DISJOINT and ADDITIVE: it imports szl_energy_provenance (#331) when present
+to source real beats, and falls back to a byte-identical local chain so it self-tests
+standalone with no network and without serve.py running.
