Picks up lambdasistemi/amaru-bootstrap PR #38 — the era-history
wiring + chain-DB-resolved nonce tail fix that closes
lambdasistemi/amaru-bootstrap#37. Required preconditions:

- amaru #2 (saturating epoch subtraction)
- amaru #3 (ln(1-f) guard for activeSlotsCoeff = 1)
- amaru #4 (--era-history-file on import-nonces +
  convert-ledger-state, GO snapshot retention)

All five fixes are in the new producer image; cardano_amaru and
cardano_amaru_epoch3600 testnets repinned.

The composer's "Always: zero exit" property still flagged
stub/parallel_driver_asteria_player.sh (failing examples at vtimes
~272s, ~291s, ~3017s on the 2026-05-03 run). Each failing example
exits 1 in ~3s with empty stderr — consistent with an exception
escaping main from withN2C / readWalletKey before the inner
try wrapper covers it.

Mirror the c99e992 BootstrapMain pattern: wrap the whole pass in
a top-level try; on SomeException emit
asteria_player_pass_top_errored_<id> as sdkUnreachable and exit 0.
The inner observeAndAct try is preserved (same payload signal name
asteria_player_pass_errored_<id>) so the two failure surfaces stay
distinguishable in the report.

Pulls in:
- adversary:b8a0521 — emits SDK assertions per attack (Reachable
  adversary_chain_sync_started + Sometimes adversary_chain_sync_completed)
- sidecar:b8a0521 — finally_tips_agree.sh emits finally_perturbation_metrics
  with blocks_produced_total and max_slot_lag

Both pins resolve to the post-cabal-fix sidecar feat commit so
publish-images can rebuild against the corrected build-depends list
(directory + filepath were missing in the first push).

Adds an emit_perturbation_metrics() helper to
components/sidecar/composer/convergence/finally_tips_agree.sh that, on
every run, computes:

  - blocks_produced_total : sum of producers' block heights at end-of-test
  - max_slot_lag          : max(slot) − min(slot) across producers

and emits them as a Sometimes(true) "finally_perturbation_metrics" event
with both numbers in details. The Antithesis report's per-bucket
distribution view then shows the curve across runs without needing a
separate observer.

Slot lag is 0 on a perfectly synchronous cluster, mildly positive
under fault injection, large under attack pressure — gives us a
quantitative comparison for master vs adversary side-by-sides.

Layer 3 of three for issue #123.

Adds Adversary.SDK with Reachable / Sometimes assertion emitters that
write to \$ANTITHESIS_OUTPUT_DIR/sdk.jsonl (default /tmp/sdk.jsonl).
Wires two assertions into app/Main.hs:

  - reachable("adversary_chain_sync_started", {target_host, point, limit})
    fires once per invocation before connectToNode. Antithesis report
    will show, segmented by target_host, "the adversary fired against
    pN at least once". A host that never gets attacked is visible as
    a missing Reachable hit.

  - sometimes(true|false, "adversary_chain_sync_completed",
              {target_host, tip|reason})
    fires once per invocation on completion. true on clean exit,
    false on connect/protocol failure. Sometimes-true vs Sometimes-
    false buckets quantify how often the adversary actually completed
    a full --limit sync vs being cut short by chaos.

Layer 1 of three for issue #123.

Pulls in:
- adversary:9b439a3 — emits SDK assertions per attack (Reachable
  adversary_chain_sync_started + Sometimes adversary_chain_sync_completed)
- sidecar:9b439a3 — finally_tips_agree.sh emits finally_perturbation_metrics
  with blocks_produced_total and max_slot_lag

Both pins move to the SHA that introduces the perturbation Layer 1
+ Layer 3 changes.

write to \$ANTITHESIS_OUTPUT_DIR/sdk.jsonl (default /tmp/sdk.jsonl).

The two adversary docs described the long-running daemon shape that
was retired in #110. Rewrites both pages to match the current state:

- adversary.md — sleep-forever container, single CLI per tick, single
  driver with --target-host fan-out over all 5 cluster hosts,
  --seed-driven random pick. New CLI flag table. New compose
  fragment. Local test loop via scripts/smoke-test.sh
  cardano_node_adversary. Closing section explains why the daemon
  was retired (two schedulers, targeting bias, lifecycle complexity
  for no benefit).
- adversary-roadmap.md — restructures around CLIs, not endpoints.
  Each future archetype is one binary + one driver, not a new daemon
  endpoint. Tier list preserved; "what's behind us" replaces the
  daemon-era status table. Tickets section reflects the closures
  done in PRs #110 and #122.

Also drops the dead adversary-CI.yaml badge from the top README —
that workflow was retired in 9bc9b23.

The faults-enabled 1h Antithesis run on cardano_node_tx_generator
(commit 12a80b8, session 95887c0ae21ed981bf9e85943bda257f-50-7,
report OOdYZcg__MdS4qqvkORdLTR-) flagged 2 driver-script findings:

  tx-generator/parallel_driver_refill.sh        command_runtime=25.78s
  tx-generator/eventually_population_grew.sh    command_runtime=24.54s

both with command_return_code=1 and empty stderr. Reading the
indexed log streams returns 0 events for these scripts' .err
streams — they didn't crash, they were killed by the composer's
per-step deadline while blocked inside 'nc -U' against the daemon's
control socket.

Likely path: under a specific fault window the daemon's accept loop
wedges (mid-reconnect / mid-deadlock during a network-partition or
node-pause event), 'nc -U -q 1' has no kernel-side timeout to bail
on, the composer wrapper's ~25s deadline fires, exit code propagates
as 1 — surfacing as a finding on the built-in 'Commands finish with
zero exit code' Always property.

Wrap each control-socket request in 'timeout --kill-after=2s 5s sh -c
"..."' so any blocked nc is bailed out within 5s + 2s SIGKILL grace,
the empty-RSP branch hits the 'tx_generator_*_daemon_unreachable'
Reachability marker, and the script exits 0. The underlying daemon
wedge is a separate ticket on the upstream cardano-node-clients repo
— this composer fix masks the symptom so the testnet baseline isn't
contaminated by it.

The two adversary docs described the long-running daemon shape that
was retired in #110. Rewrites both pages to match the current state:

- adversary.md — sleep-forever container, single CLI per tick, single
  driver with --target-host fan-out over all 5 cluster hosts,
  --seed-driven random pick. New CLI flag table. New compose
  fragment. Local test loop via scripts/smoke-test.sh
  cardano_node_adversary. Closing section explains why the daemon
  was retired (two schedulers, targeting bias, lifecycle complexity
  for no benefit).
- adversary-roadmap.md — restructures around CLIs, not endpoints.
  Each future archetype is one binary + one driver, not a new daemon
  endpoint. Tier list preserved; "what's behind us" replaces the
  daemon-era status table. Tickets section reflects the closures
  done in PRs #110 and #122.

Also drops the dead adversary-CI.yaml badge from the top README —
that workflow was retired in 9bc9b23.

Rebases on current main (which now has the workflow inputs.test fix
e3b09a0 and the publish-images all-testnets glob 81f3bf1, so the
sibling publish workflow + script from earlier iterations of this
branch are dropped). Master-side files (testnets/cardano_node_master/,
scripts/, master workflows) are untouched.

Adds:

  * testnets/cardano_node_tx_generator/{docker-compose.yaml,
    testnet.yaml,relay-topology.json,tracer-config.yaml,README.md}
    — mirrors master's image set 1:1 (cardano-node x3 by digest,
    cardano-tracer by digest, configurator/log-tailer/tracer-sidecar
    by digest, sidecar:65039df) plus the tx-generator service
    active. Network name 'cardano-node-tx-generator-testnet' to
    avoid collision with master's network when both run on the
    same docker daemon.
  * components/tx-generator/flake.nix bumped to upstream
    711eb22ac03e67b753f7ce70e635cddcf6f3cdce — full
    reconnect-resilience stack: PR #105 (supervisor +
    BlockedIndefinitelyOnSTM catch), #110 (post-reconnect indexer
    freshness gate), #114 (pre-submit chain-tip probe), #115
    (refill duplicate-submit recovery), #116 (recovery-await timeout
    aligned with dcAwaitTimeoutSeconds), #117 (refill recovery-await
    timeout -> IndexNotReady), #118 (same recovery in transact arm).
  * Composer scripts hardened (set -u, always exit 0, lastTxId gate
    on did_not_grow).
  * docs/components/tx-generator.md — daemon architecture: composer-
    as-clock contract, deterministic per-request flow, single-bearer
    N2C topology with in-tree address-to-UTxO indexer, NDJSON wire
    schema with response classes, per-request build/probe/submit/
    recovery flow, reconnect-resilience PR stack, composer scripts
    convention, persistent state, assertion classes.
  * docs/testnets/cardano-node-tx-generator.md — testnet rationale,
    image-set parity table with master, dispatch invocations, ref to
    the repo-wide publish-images flow.
  * mkdocs.yml — Components and Testnets nav entries.

Verified clean on a 1h no-faults Antithesis dispatch:
findings_new=0, all tx_generator_*_landed assertions firing, no
tx_generator_*_submit_rejected. Compose tag in this commit is
PLACEHOLDER; the next commit on this branch sets it to this commit's
SHA so publish-images.sh can resolve it as a downstream commit ref.
