That pulled a second protocol lineage into the graph, so any target bridging ant-core and ant-node (devnet, E2E, merkle-e2e tests) saw two incompatible copies of `ant_protocol::transport::P2PNode` and failed to compile with E0308. Point all three pins at the matching rc branches so the graph collapses to a single git-rc lineage.

A handful of quorum-short chunks therefore parked the wave's other ~63 slots idle through multiple backoffs — the single biggest throughput sink on the PROD-UL-01 run (one wave alone burned 34 minutes). Port the download path's deferred-retry design to the upload path: - Store each wave in a single pass (`max_attempts = 1`, no backoff) so a wave never blocks on a slow chunk. - Collect quorum-short chunks into a file-level deferred set and advance to the next wave immediately. - After the last wave, retry the whole deferred set in concurrent rounds with `[0, 15, 45]s` delays (matching the download path), re-reading each chunk's body from the spill at retry time (peak RAM unchanged) and reusing its proof. Failure semantics are preserved: chunks still short after the final round surface as `PartialUpload`; a non-quorum error aborts as `PartialUpload` while preserving earlier progress. Stats and progress numbering are carried across rounds, with each deferred round's successes recorded in its own histogram slot. Total per-chunk retry budget is unchanged (1 wave pass + 3 deferred rounds). Adds `merkle_deferred_retry`, `DeferredRetryOutcome`, `deferred_round_histogram_slot`, `DEFERRED_ROUND_DELAYS_SECS`, and unit tests.

charset=UTF-8 Content-Transfer-Encoding: 8bit The adaptive store concurrency limiter never ramped from its cold-start of 8 and got crushed to a +1-per-window crawl because two non-capacity signals polluted its health input on the merkle upload path: - Node-side PUT latency is dominated by the ~28s synchronous merkle closeness lookup, inflating client-observed p95/median to 3-6x and tripping the latency-vs-baseline Decrease even though nothing about it is local congestion. - Remote application rejections (pool-rejected, disk-full, quote-stale) arrived as Error::Protocol / flattened Error::InsufficientPeers and were classified as NetworkError, counting against success_target and driving multiplicative decrease. With the default slow_start_ramp_threshold of 0, a single such Decrease permanently exited slow-start. Apply the fetch-channel precedent to the store channel (the situation is structurally identical — verification variance instead of retry variance), plus preserve the structured remote rejection reason so it classifies correctly. The cold-start floor of 8 is deliberately unchanged. - adaptive.rs: store_cfg.latency_decrease_enabled = false and store_cfg.slow_start_ramp_threshold = usize::MAX, so a transient Decrease halves but the next healthy window re-doubles. Genuine store congestion still surfaces via the timeout-rate ceiling. - error.rs/chunk.rs: new Error::RemotePut { address, source: ProtocolError } carrying the structured upstream discriminant instead of stringifying it into Error::Protocol. A ChunkPutResponse::Error means the transport round-trip succeeded and the node declined at the application layer. - chunk.rs: chunk_put_to_close_group surfaces a representative RemotePut for app-only quorum shortfalls; any genuine transport failure keeps it InsufficientPeers so real congestion still cuts the cap. - mod.rs: classify_error maps RemotePut to ApplicationError. - merkle.rs: merkle_store_with_retry treats RemotePut as recoverable (defer/retry) like InsufficientPeers, so transient rejections don't abort the upload. Adds unit coverage: store ramps/recovers under the new tuning while a timeout burst still cuts it; remote app-rejections don't move the cap; RemotePut is recoverable in the retry path.

Memory bound (high): the deferred pass read every quorum-short chunk in the whole file into one Vec per round before storing, so peak resident bodies scaled with the file-wide deferred count rather than the wave path's ~UPLOAD_WAVE_SIZE / ~256 MB bound. merkle_deferred_retry now takes a batch_size and processes each round in batches of that size, re-reading only one batch of bodies from the spill at a time. The CLI caller passes UPLOAD_WAVE_SIZE. 2. Fatal-abort accounting (medium): merkle_store_with_retry returned Err on a non-quorum error, discarding the successes already recorded in that pass; the wave/deferred callers then built PartialUpload from stale state (could report failed_count = 0 and omit same-pass stores). The store helper now preserves same-pass successes (stored/stored_addresses), records the fatal chunk as failed, and surfaces the error via a new MerkleStoreOutcome::fatal field instead of Err. The external-signer path re-raises fatal as Err to keep its all-or-nothing contract; the CLI wave and deferred paths fold it into a PartialUpload whose failed set is derived authoritatively as every input chunk not in stored_addresses (shared partial_upload_after_fatal helper), so stored_count + failed_count accounts for the whole file. This also fixes the pre-existing wave-path under-reporting the review noted. Tests: same-pass successes preserved on fatal; deferred reads bounded to batch_size; updated the non-quorum-error test to assert fatal-in-outcome. cargo test -p ant-core --lib -> 338 passed; clippy and fmt clean.

Display consumers (the GUI) were left with no value to show. - Distributed sampling: sample addresses spread evenly across the whole chunk list instead of the first N (distributed_sample_indices, unit- tested). Files with <= cap chunks still sample every chunk, preserving exact "whole file sampled" detection. - The residual all-stored-but-incomplete case returns Ok with storage_cost_atto "0" instead of erroring, tagged with a new CostEstimateConfidence enum (PricedSample / VerifiedAllAlreadyStored / AllSamplesAlreadyStoredIncomplete). The CLI renders the confidence. UploadCostEstimate is now #[non_exhaustive] with a #[serde(default)] confidence field. Error::CostEstimationInconclusive is retained (no longer produced) to avoid removing a public variant. BREAKING CHANGE: UploadCostEstimate is #[non_exhaustive] and gained a `confidence` field; downstream code constructing or exhaustively destructuring it must update.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add `Client::file_download_to_sender`, which downloads + decrypts a file and streams the plaintext to a caller-provided `mpsc::Sender>` instead of writing to disk. Constant memory (one decrypt batch resident at a time, same as `file_download`), and the caller receives bytes progressively as each batch decrypts — suitable for forwarding to an HTTP chunked body or a gRPC response stream. The bounded sink applies backpressure; a dropped receiver (client disconnect) ends the download early. Implemented by extracting the existing batched-fetch + streaming-decrypt loop out of `file_download_with_progress` into a private sink-parameterized core, `download_decrypted_chunks(.., on_chunk)`. `file_download_with_progress` is now a thin wrapper whose sink writes to the temp file + atomic-renames (behavior unchanged); the new method's sink forwards to the channel. No duplication of the fetch/retry logic, and `&self` is preserved (the caller spawns + owns the Receiver), so no `Client: Clone`/`'static` bound is required. Adds an e2e round-trip test that streams a multi-batch (~1 MiB) file through the channel and asserts the reassembled bytes equal the source.

In PROD-UL-02 this turned ~85% per-chunk success into 0% per-file success, killing every upload at wave 1 of N. Align it with the merkle path (`upload_waves_merkle`): a wave short of quorum records its failed chunks and continues; after all waves are attempted the file returns a single `Error::PartialUpload` with the full stored/failed breakdown. Genuinely fatal errors (wallet/payment infrastructure, missing proofs, spill reads) still abort immediately. The recoverable-vs-fatal decision is factored into a pure `fold_single_wave` helper with unit tests. Because `UPLOAD_WAVE_SIZE == PAYMENT_WAVE_SIZE`, each batch call is exactly one payment wave, so folding its `PartialUpload` leaves nothing un-attempted within the wave. Also surface on-chain spend on a partial upload: a partial still pays for the chunks it paid for, but the spend was silently dropped. Add a boxed `PartialUploadSpend` (storage_cost_atto + gas_cost_wei) to `Error::PartialUpload`, populate it at every raise site (single-node, merkle, external-signer), and report it in the CLI (human + JSON). Boxed to keep `Error` under clippy's `result_large_err` threshold.

Cap store concurrency in store_paid_chunks_with_events by combined in-flight body bytes (STORE_INFLIGHT_BYTE_BUDGET, 64 MB) instead of chunk count, so ~4 MB chunks drop to ~16 concurrent stores while small chunks are unaffected. This is the standalone memory fix; no saorsa-core change is required.
