- write proc_card_mg5.dat at output and embed it as <MG5ProcCard> in the LHE
banner (with <slha>/<MG7RunCard>/<init>) so MadSpin/reweight can read the
model+process from mg7 events
- fix the LHE <init> beam PDGs: use 2212 for hadronic beams (incoming is the
parton, not the beam)
- scope the TOML run_card editor overrides (define_paths/init_run/do_set) to
MG7Selector instead of globally patching AskforEditCard; the global patch
leaked into MadSpin's spawned madevent and broke its run_card handling
('dict' object has no attribute 'blocks')
- map the legacy 'nevents' key to [generation].events on RunCardMG7
- auto-set output_format=lhe when a post-processing tool (shower/detector/
madspin/reweight/analysis) is enabled in the merged question
- pass --lhapdf_config to systematics so it can link the python lhapdf module
- write post-processing tracebacks to a <tool>_crash.log file and print its
path; raise a clear error when the per-event <mgrwt> reweighting info is
missing (mg7 does not write it yet)

- add a Pythia8 driver (_run_pythia8) that showers the mg7 LHE through the MG5aMC_PY8 interface and writes a HepMC file next to the events, mirroring the core of MadEventCmd.do_pythia8 (single sub-run, HepMC output) - veto the MLM/CKKW merging sentinels and set Main:numberOfEvents to the event count (fixed-order LO: no merging), avoiding the -1 out-of-range crash - load mg5amc_py8_interface_path and heptools_install_dir in load_mg5_options - wire shower==Pythia8 into run_selected_tools; failures go through _report_failure (traceback written to Pythia8_shower_crash.log, path printed) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
At output time, ProcessExporterMG7 now writes process-tailored MA5 default cards (madanalysis5_parton/hadron_card_default.dat), mirroring the madevent exporter. At launch time, the mg7 driver runs MA5 on the LHE (parton level) and, when Pythia8 ran, on the HepMC (hadron/reco level). To make MA5 recognise the process legs, add VirtualExporter.expand_merged_particle_legs(), which expands the merged-flavor beam PDG codes (81/82/83 and conjugates) to concrete signed flavour PDGs via the model's merged_particles map. This is also wired into the fortran create_default_madanalysis5_cards path, fixing the same MultiParts failure there (the merged codes never matched a multiparticle definition).

The mg7 (standard) launcher previously re-implemented each post-processing tool standalone (single-core Pythia8, direct MadSpin/MA5 calls). Replace all of that with MG7RunCmd, a thin MadEventCmd adapter pointed at the mg7 output, and drive the real madevent tool commands (reweight, decay_events, shower, delphes, madanalysis5_parton/hadron, rivet) via exec_cmd. The headline win: Pythia8 is now showered in parallel over the cluster/multicore backend, identical to a madevent run (LHE split into per-core jobs, HepMC merged) -- validated with 200 events split into 2 x 100. MadSpin, MA5 parton and MA5 hadron (reco) also run through their standard drivers, with output landing in the normal HTML/<run> layout. MG7RunCmd reconciles the mg7 layout with what MadEventCmd assumes: - configure_directory: no Fortran Source to compile / LHAPDF to link; - set_run_name: load the run card from run_card.toml (RunCardMG7) and take the banner straight from the mg7 LHE; - load_results_db: build a fresh results db without recreate() (the mg7 banner has no <MGGenerationInfo>); the run is registered explicitly; - do_set/do_treatcards: skip the Fortran-compiler / .inc-file machinery; - _prepare_run_dir: expose unweighted_events.lhe.gz for the tools. Supporting changes: - export_cpp (ProcessExporterMG7.finalize): write SubProcesses/proc_characteristics (ninitial/nexternal/initial-PDGs/ISR-FSR) and Cards/me5_configuration.txt so get_characteristics()/set_configuration() work on the mg7 directory. - banner (RunCardMG7): add a run_tag param and legacy-compat keys the tools read (ktdurham/ptlund/xqcut/maxjetflavor/sys_matchscale/dparameter/lhaid/iseed/ python_seed), all taking their "no MLM/CKKW merging" values.

run_selected_tools issued each tool command with an explicit "run_01" run name, so after decay_events (which repoints self.run_name to the new "<run>_decayed_i" run, as MadEventCmd.do_decay_events does) the shower and analyses still acted on the original, undecayed run. Drop the explicit run name so the commands follow cmd.run_name, exactly like MadEventCmd.do_launch: reweight runs on the generated events, then MadSpin repoints the run, and the shower / MA5 / Rivet that follow act on the decayed events. MG7RunCmd.set_run_name now resolves the banner+LHE from the run's own Events/<run> directory (falling back to the original mg7 LHE), so the decayed run is handled correctly. Verified: with MadSpin+Pythia8, the shower HepMC now lands in Events/run_01_decayed_1/ and showers the decayed events. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The standalone mg7 launcher never configured Python logging, so the reused
madevent tool drivers narrated everything through logger.info / update_status
("Running Pythia8 [arXiv:...]", "Splitting .lhe event file...", the live
Idle/Running/Completed job counters, "Running MadSpin", ...) into loggers with
no handler -- all of it silently dropped.
_setup_tool_logging() attaches a colored INFO console handler to the
'madgraph'/'madevent'/'cmdprint' loggers (reusing coloring_logging.ColorFormatter),
so those existing messages now appear. It is called from run_selected_tools, so
only the post-processing phase is affected (propagate=False keeps it from
touching the generation-phase output).
run_selected_tools also prints a one-line summary of the selected tools and a
clear banner + timing around each step (start / "-> done (Ns)" / failure).

run_selected_tools invoked madanalysis5_hadron whenever analysis==MadAnalysis5, so with the shower OFF it ran and immediately reported "No hadron level input found ... Skipping". Gate it on the shower being on (shower != OFF), mirroring madevent's own card condition (analysis == 'MadAnalysis5' and shower != 'OFF'). The summary line of selected tools is gated the same way. The card-editor side already hides madanalysis5_hadron_card.dat when the shower is off (inherited switch_cards/active_cards gating), verified in the live question; this only fixes the run side.

The new mg7 post-processing jobs (time-of-flight/Pythia8/Rivet/MadSpin) restored the granular per-tool caches (restore_heptools_lhapdf/_pythia8/ _contur, keys lhapdf-<os>/pythia8-<os>/contur-<os>). Those per-tool caches are evicted by GitHub's cache limits, so the restore was a silent miss: the tool paths got configured but the binaries were absent, the tests self-skipped, and test_manager.py turns a skip into exit 1 -> red jobs (while the madevent jobs stayed green because they restore the combined heptools-<os> cache). Point every mg7 job at restore_heptools (the combined cache the madevent jobs use, which bundles LHAPDF+NNPDF23, Pythia8 and Rivet/contur) and make restore_heptools fail-on-cache-miss so a genuinely missing heptools-<os> cache crashes loudly (naming the key) instead of degrading into opaque skips. Drop the dedicated Delphes job (Delphes is not in the cache; the test_delphes_mg7 method stays and self-skips where Delphes is absent). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The post-processing log lives in a tmp dir CI does not upload, so a failing mg7 generate_events only reported an opaque rc=1. Dump the last 120 lines of the log into the test failure so the real crash is visible in CI. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Rivet test used p p > e+ e- and the MadSpin test used p p > w+; both hit mg7/madspace generation limits unrelated to the post-processing chaining: - p p > e+ e- crashes the madspace LHECompleter (unordered_map::at) when writing the LHE; - p p > w+ is 2->1 and madspace requires >=2 outgoing particles. Switch both to the 2->2 p p > w+ z (already proven by the tof/Pythia8 tests to generate and write LHE cleanly) so the tests exercise the Rivet/MadSpin command interface chaining rather than these generator gaps. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Generation now succeeds for the Rivet/MadSpin tests but the tools produce no output and run_selected_tools swallows tool failures (rc stays 0). Echo the generate_events log tail and any per-tool *_crash.log to stderr so the silent Rivet/MadSpin failure is visible in CI. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
With the correct heptools cache the tof and Pythia8 mg7 post-processing tests pass, but Rivet and MadSpin hit genuine mg7 gaps (the command interface drives the chain correctly; the underlying tool support is not there yet): - Rivet: the mg7 driver logs "Skipping Rivet for now, passing it to postprocessor" and writes no rivet_result.yoda. - MadSpin: aborts with "Invalid proc_card information in the file (no generate line)" -- the mg7 LHE banner does not yet carry the proc_card in the form MadSpin do_import expects, so no decayed events are produced. Mark both @unittest.expectedFailure (mirroring the existing test_madspin_mixed_flavor_decay_log_summary_mg7) so CI is green while the gaps stay tracked and flip to an unexpected success once mg7 wires up each tool. Also revert the helper diagnostic to only dump the generate_events log on a hard crash (rc != 0). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…mplete The MadSpin chaining test failed with "Invalid proc_card information in the file (no generate line)". Root cause: _run_mg7_postproc built the mg7 output with mg.exec_cmd(), which does not record the interface history. The exporter dumps that history into Cards/proc_card_mg5.dat (and thus the LHE banner <MG5ProcCard>), so the model/generate/output lines were missing and MadSpin (which reads the generate line from the banner) aborted. Driving the output through run_cmd -- as a real user does via bin/mg5_aMC -- records the history and writes a complete proc_card, so MadSpin gets its generate line. Also surface any non-systematics per-tool *_crash.log from run_selected_tools (a tool that fails without failing generate_events) and drop the MadSpin @expectedfailure now that the banner is complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Development-phase policy: CI should crash to remind us what still needs to be
implemented before release, rather than masking gaps as expected failures.
- test_rivet_from_file_mg7: mg7 Rivet driver not wired up ("Skipping Rivet for
now, passing it to postprocessor") -> now red.
- test_madspin_mixed_flavor_decay_log_summary_mg7: mg7 + MadSpin density
summary not wired up -> now red; give its job restore_heptools so the red
reflects the real gap rather than a missing NNPDF23 PDF.
(The mg7 MadSpin decay chaining, test_w_production_with_ms_decay_mg7, already
passes after the proc_card banner fix.)

So the real reason the mg7 + MadSpin density-summary test fails is visible in CI output instead of only which assertion tripped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The mg7 run_card is TOML (generation.events, default 100000). The launch card
editor did not map the madevent legacy name nevents to it, so a madevent-style
launch script ("set nevents 500") was silently ignored and the run generated
the full 100k events -- test_madspin_mixed_flavor_decay_log_summary_mg7 then
decayed 100k events in ~166s, dangerously close to its 240s timeout.
MG7Selector.do_set now routes the legacy LO run_card names through
RunCardMG7._LO_SCALAR_MAP (nevents->generation.events, use_syst->..., etc.), so
madevent launch scripts edit the mg7 run_card.toml verbatim. This makes the
mixed-flavor MadSpin test generate the intended 500 events (fast, not flaky).
Also: refresh the now-stale KNOWN-FAILING wording (the test passes) and print
the mg7 log tail only on failure.

do_rivet only prepares Events/<run>/run_rivet.sh and defers execution to the postprocessor (the rivet_card default has run_rivet_later = True, so with --no_default it logs "Skipping Rivet for now, passing it to postprocessor" and appends the run to cmd.postprocessing_dirs). MadEventCmd.do_launch runs that postprocessor at the end of a run; run_selected_tools never did, so mg7 wrote no rivet_result.yoda. Call cmd.postprocessing() after the shower (MG7RunCmd inherits it from MadEventCmd), which executes the deferred run_rivet.sh -> yoda and, when run_contur = True, Contur. Flip test_rivet_from_file_mg7 back to a real pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
_report_failure name had a / (Rivet/Contur) which put the crash log in a nonexistent subdir; renamed to Rivet-Contur. Temporarily dump the mg7_postproc.log tail and Events/**/rivet*.log to diagnose why no yoda. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Root cause of the empty Rivet run: the Pythia8 driver writes <tag>_pythia8_events.hepmc and only *schedules* the .gz compression via the deferred to_store list; the actual gzip to <tag>_pythia8_events.hepmc.gz happens in store_result(). MadEventCmd.do_launch calls store_result() right after the shower/detector/analysis tools, but run_selected_tools never did, so the HepMC stayed uncompressed while the deferred run_rivet.sh reads the .gz path (the pythia8_card default is HEPMCoutput:file = hepmc.gz). Rivet then aborted with "deduce_reader: file ...hepmc.gz does not exist". Call cmd.store_result() after the tool loop (mirroring do_launch) so the HepMC is gzipped before the Rivet/Contur postprocessor runs. Remove the temporary rivet diagnostics.

The merged (switch + card editing) launch question asked ask() without path_msg. path_msg is what Cmd.check_answer_in_input_file uses to enable its "elif path:" branch, so in a scripted run a bare card path was rejected with "This answer is not valid for current question. Keep it for next question and use here default: 0" and silently replaced by the default -- even though the question advertises "enter the path to a valid card or banner" and the interactive flow handles it (AskforEditCard.default -> copy_file -> detect_card_type). Regression from the question merge (b2075d3); the old ask_edit_cards question passes path_msg. Pass path_msg in both merged questions (madevent ask_run_configuration and the mg7 ask_edit_cards). test_generation_from_file_1 now copies run_card_matching.dat over run_card.dat as intended.

…ing) Drives matrix-element reweighting through the mg7 command interface: generate p p > t t~ with the mg7 output, select reweight=ON in the launch question and let run_selected_tools chain "reweight -from_cards" on the events, reweighting to a heavier top. Asserts every event carries the new rwgt_1 weight. The reweight module rebuilds the matrix element from the model/process stored in the LHE banner, so this also exercises the banner proc_card.

For "define q = u d; generate u q > u q" the u d contribution came out twice
too large: export_mg7 decided whether the beam-swapped initial state belongs to
the process with
same_initial_multiparticle = self.incoming[0] == self.incoming[1]
i.e. by comparing the pdg of the *matrix-element* legs. With flavor merging both
initial legs carry the same merged pdg (81), so this was True even though leg 1
is fixed to u -- and the mixed u d flavor then got mirrored, adding a "d u > u d"
initial state that is not part of the process at all.
madevent gets this right (write_mirrorprocs) by using the *process definition*
per-beam multiparticle content. Factor that logic out as
Process.has_same_initial_multiparticle() and use it from both exporters, so they
cannot drift apart.
u q > u q -> (2,) vs (1,2): no flavor mirrored (was: u d mirrored -> x2)

e+ e- > e+ e- came out twice too large in mg7 (81 pb instead of 40.3): get_initial_leg_signature compared |pdg|, so the e+ beam (-11) and the e- beam (+11) both reduced to (11,) and looked like the same multiparticle. The mixed e+ e- flavor was then mirrored -- but the beams are different particles, so the swapped initial state is not part of the process at all. Compare the *signed* flavor content instead (get_initial_flavor already returns signed pdgs; only the signature threw the sign away). madevent is unaffected: its flavor lists are unsigned, so its per-flavor guard (flv[0][0] != flv[0][1]) already suppressed the mirror for e+ e-; it now takes the same decision one step earlier. Verified: e+ e- / u q > u q / q q > q q all keep their madevent mirrorprocs.inc, and test_e_e_collision still reproduces 155.9 pb with run_card_ee.dat. mg7 e+ e- > e+ e- now gives 40.44 +- 0.42 pb (madevent: 40.3). test_e_e_collision_mg7: assert the mirroring explicitly on top of the cross-section, and pin it to the madevent value for the *same* run_card (40.3); the old 155.9 reference belongs to test_e_e_collision run_card_ee.dat and never applied here. Also cover e+ e- in the fast output-level mirroring test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…l on) Re-launching an mg7 output turned every tool (pythia8/madspin/reweight/...) on instead of remembering the previous run. The merged launch question materialises every candidate tool card (copies the *_default.dat) so it can offer them for edition, and set_default_<tool> keys the switch default off card presence. madevent prunes the unselected cards afterwards (ask_run_configuration -> keep_cards on the selected cards), but the mg7 launcher had no such cleanup, so the materialised cards persisted and the next launch saw them all present -> every switch defaulted to ON. add prune_unselected_tool_cards() and call it from ask_edit_cards, using the questions own switch->card map. A re-launch now reflects the previous selection (e.g. select nothing -> all OFF; select pythia8 -> shower=Pythia8, rest OFF). Regression test test_relaunch_switch_defaults_mg7 drives the real question twice; it is output-level (no madspace runtime) and fails without the prune.

This include the run_card refactoring (that needs to be merged first).
But modifies the question such that we can decide to run Pythia8/MA5/Delphes/MadSpin/...
reweighting is still linked to the old module (need to be replaced by MadTrex).
One still need to check that all linking are working (but claude tells me that i can not write valid lhef file locally from madspace ...)
