What's New In This PR

Issue #9 — Agenda-driven loop

• agents/research_agenda.py + agents/agenda_loop.py drive Plan → Execute →
  Review → Revise → Repeat with explicit status enum and gated transitions.
• Synthetic-data guard: require_submission_ready() blocks experiment data
  that came from RNG-only fixtures.
• Real benchmark fixture (tests/fixtures/qkv_benchmark.npz) replaces
  RNG-only flow; gate fails closed when it's missing.
• Magnitude check (post-audit fix): agents/evidence_gate.py enforces
  RELATIVE_ERROR_MAX = 0.10. An approximation with > 10% relative error
  against softmax is inconclusive and must not flow into manuscript
  generation. The committed artifacts/agenda_loop_acceptance.json records
  a real bench against the committed
  agents/benchmarks/qkv_fixture_512_64.npz fixture (seq_len=512,
  head_dim=64) that produces rel_err ≈ 0.767 and correctly blocks
  manuscript creation (gate.status="block", manuscript.created=false).
  This is the intended end-to-end behavior: the agenda loop must reach a
  small-enough error before it will write a paper. Prior to the audit fix
  the gate greenlit the same packet, which the reviewer correctly flagged
  as inconclusive. Pass-path coverage is exercised in
  tests/test_evidence_gate.py::test_pass_path_creates_manuscript_with_acceptable_rel_err
  and tests/test_evidence_gate_routes.py::test_gate_endpoints_pass_and_fetch,
  which patch the packet's delta.relative_error to 0.05 before gate
  evaluation and verify the bench → gate → manuscript → review chain
  end-to-end.
• agents/reviewer_adapter.py registers two reviewers:
  • internal_evidence_gate (default) — rule-based aggregation of
    hypothesis_verdict + effect_size + claims + evidence_plan. Deterministic,
    no network.
  • claude-haiku-4-5 — real LLM reviewer. Tries Anthropic Messages API
    (ANTHROPIC_API_KEY → claude-haiku-4-5-20251001) first, then falls back
    to a locally-authed claude CLI subprocess. The reviewer field on the
    persisted AgendaReview row is stamped with the actual transport+model
    used (e.g. anthropic_api:claude-haiku-4-5-20251001 or
    claude_cli:claude-opus-4-6) so the evidence trail is honest about what
    produced each review.
  • Choose at run-time with DEEPGRAPH_REVIEWER=claude-haiku-4-5; set
    DEEPGRAPH_REVIEWER_FALLBACK=internal_evidence_gate (default) so the
    build script remains green on machines without LLM credentials.

Issue #12 — TemplateAdapter + VenueRouter

• agents/manuscript_templates/__init__.py exposes TemplateAdapter ABC and
  get_adapter(template_id) factory.
• agents/venue_router.py reads agents/venues.yaml (single source of truth
  for 6 registered venues) and returns (primary, secondary, reasons).

Issue #13 — Four new venue adapters

• New in D2: neurips2024, icml2024, acl_arr, cvpr2024
  (alongside the D1-shipped iclr2026 and arxiv_plain adapters,
  for 6 registered venues total).
• Each adapter ships a stub .sty + third_party/<venue>/README.md
  (source URL, license, redistribution policy); the full upstream .sty
  is pulled at real submission time per the README.
• _StubVenueAdapter base in
  agents/manuscript_templates/_stub_adapter.py factors the shared
  inject_preamble / normalize_source / copy_files plumbing; the four
  venue subclasses only declare their venue-specific constants
  (_sty_basename, _bibstyle, _max_pages, _column_layout).
• submission_mode toggle flips between double-blind review
  (\usepackage[review]{<sty>}) and camera-ready
  (\usepackage[final]{<sty>}); D1's iclr2026 adapter additionally
  emits \iclrfinalcopy in camera-ready mode.

Issue #14 — FormatLinter

• agents/format_linter.py runs 12 checks (rule_set=format_linter_v1):
  • 7 structural — documentclass_present, bibstyle_matches_venue,
    required_packages_present, page_count_within_budget,
    figure_placement_specifiers, column_layout_consistency,
    figure_grid_density.
  • 5 mandated by issue [D3] FormatLinter (5 checks) + evidence gate + LLM tiebreaker (排版质量门 + 路由 LLM 兜底) #14 (verbatim names) — font_size_consistency,
    section_spacing, float_density, citation_density,
    bib_style_match.
• persist_lint_run / get_lint_run round-trip through format_lint_runs.
• tests/test_format_linter.py::test_dirty_fixture_triggers_all_five_issue14_checks
  trips each mandated check independently.

Issue #15 — API + dashboard

• web/manuscript_routes.py blueprint: /api/manuscript/route,
  /api/manuscript/lint, /api/manuscript/bundles.
• Dashboard "Manuscript Routing" panel (under web/templates/dashboard.html).
• scripts/demo_full_paper_compile.py builds across all 6 venues — 10/10
  PDFs with real matplotlib figures (PPL vs context length, wallclock log-log
  with slope annotations, feature-dimension ablation).

Docs Updates

• README.md — new "Manuscript Venue Routing" section (14 lines).
• docs/top_venue_manuscript_chain.md — rewritten with router → adapter →
  linter → gate diagram + evidence trail table; drops the prior ICLR-only
  hard constraint.

Architecture — Mapping To The Three Client Requirements

The client brief listed three contract bullets. Each maps to a concrete code
path so a deep reviewer can validate without grepping:

(1) 解耦 — Venue logic is plug-in

• agents/manuscript_templates/__init__.py exposes the TemplateAdapter
  ABC + a @register("<template_id>") decorator + a get_adapter()
  factory backed by a module-level registry. Adding a new venue is:
  (a) drop a module under agents/manuscript_templates/,
  (b) decorate the subclass with @register("my_venue"),
  (c) add one entry to agents/venues.yaml. No edits to any pipeline
  driver, router, linter, or web route.
• agents/manuscript_templates/_stub_adapter.py factors the shared
  inject_preamble / normalize_source / copy_files plumbing for the four
  D2 venues (NeurIPS/ICML/ACL/CVPR), so the per-venue subclass only
  declares 4 constants (_sty_basename, _bibstyle, _max_pages,
  _column_layout).
• agents/venues.yaml is the single source of truth for routing
  scores, page caps, domain triggers, and reject rules. venue_router.py
  reads this YAML; no venue-specific constants live in Python.
• End-to-end decoupling proof: scripts/demo_full_paper_compile.py
  iterates list_adapters() (registry lookup) and for every registered
  venue calls adapter.normalize_source → adapter.copy_files → tectonic compile → lint_manuscript. 10 builds (6 venues × 1 build
  each + 4 dual-mode submission/camera-ready) all produce a real PDF
  from one render-plan loop.

Decoupling closed end-to-end (post-review polish):
agents/paper_orchestra_pipeline.py now threads a template_id
kwarg through the full auto-loop:

• assemble_main_tex(state, orchestrated, bundle_format, *, template_id=None)
  — when template_id != "iclr2026", the venue-neutral skeleton is
  emitted and the adapter's normalize_source injects the chosen
  venue's preamble + bibstyle. None resolves to iclr2026 for
  conference bundles and arxiv_plain otherwise.
• normalize_latex_source(text, *, template_id=None, force_iclr2026=False)
  — explicit template_id wins, the legacy boolean is preserved
  for back-compat.
• pick_main_tex(orchestrated, state, bundle_format, *, template_id=None)
  — propagates to both branches (refined-full-text and assembled).
• generate_bundle_paper_orchestra(run_id, bundle_formats=None, *, template_id=None)
  — top-level entry accepts router output and dispatches the
  bundle-loop's copy_files call through get_adapter(...) instead
  of the hard-coded _copy_iclr2026_template_files.

Defaults are unchanged (bundle_format=="conference" → iclr2026,
otherwise arxiv_plain), so every existing call site stays byte-equivalent
(verified by tests/test_template_adapter.py::test_legacy_shim_byte_equivalent).
Three new regression tests prove the decoupling actually works:
test_normalize_latex_source_template_id_routes_to_adapter (6 venues
× adapter parity), test_normalize_latex_source_template_id_overrides_force_flag
(precedence), and test_pick_main_tex_routes_through_adapter (neurips +
acl_arr emit venue-specific preambles when invoked through the auto-loop
entry point).

Follow-up polish (commits 292d062 + 240d71e):

After the decoupling commit landed, a self-review surfaced three nits;
all three are now fixed on the branch HEAD 240d71e:

• P2 — silent ICLR fallback on unknown template_id removed
  (292d062). The bundle loop previously wrapped get_adapter(...)
  in try/except KeyError and silently re-used
  _copy_iclr2026_template_files. A bad router output (e.g.
  template_id="neurips2024" but registry miss) would have shipped
  ICLR .sty files into a NeurIPS bundle while main.tex emitted
  NeurIPS preamble — tectonic would fail with no actionable error.
  The except is gone; built-in adapters are all loaded eagerly via
  _ensure_builtin_adapters_loaded, so this only fires on genuine
  bugs.
• P3a — assemble_main_tex default template_id="iclr2026" → None
  (240d71e). Journal bundles never used the ICLR skeleton, but the
  signature implied they did. Default is now None with explicit
  bundle_format-based fallback inside the body. pick_main_tex /
  generate_bundle_paper_orchestra already used this pattern, so
  the three entry points are now consistent.
• P3b — citation_cleanup[fmt]["iclr2026_template_files"] →
  "template_files" (240d71e). The key was venue-agnostic in
  content but ICLR-named — misleading for anyone reading a NeurIPS /
  CVPR / ACL bundle's metadata. Grep confirmed no downstream reader
  (DB stores it as JSON blob), so this is a free rename.

All 50 epic-scope tests (tests/test_top_venue_adapters.py tests/test_venue_router.py tests/test_format_linter.py tests/test_manuscript_routes.py tests/test_template_adapter.py tests/test_venue_router_tiebreak.py) stay green after both polish
commits.

(2) 输出满足论文规范格式 — FormatLinter contract

• agents/format_linter.py::lint_manuscript runs 12 rule checks
  against the source against the selected adapter's contract. 7 are
  structural (documentclass_present, bibstyle_matches_venue,
  required_packages_present, page_count_within_budget,
  figure_placement_specifiers, column_layout_consistency,
  figure_grid_density); 5 are mandated verbatim by issue [D3] FormatLinter (5 checks) + evidence gate + LLM tiebreaker (排版质量门 + 路由 LLM 兜底) #14
  (font_size_consistency, section_spacing, float_density,
  citation_density, bib_style_match).
• artifacts/d3_format_linter_acceptance.json shows every registered
  venue passing the happy-fixture and failing the dirty-fixture across
  all 12 checks (all_happy_pass=True, all_bad_fail=True).
• tests/test_format_linter.py (15 tests) exercises each check
  independently. test_dirty_fixture_triggers_all_five_issue14_checks
  proves each issue-[D3] FormatLinter (5 checks) + evidence gate + LLM tiebreaker (排版质量门 + 路由 LLM 兜底) #14 mandated check trips on its own dirty marker.
• Results round-trip through SQLite (format_lint_runs table) via
  persist_lint_run / get_lint_run; the D4 API surface
  (POST /api/manuscript/lint/<selection_id>) persists + returns the
  run_id. Reviewers can re-fetch any prior lint via
  GET /api/manuscript/lint_run/<run_id>.

(3) 推荐投稿什么顶会 — VenueRouter + LLM tiebreaker

• agents/venue_router.py::evaluate_venues(state, venues_yaml) scores
  every registered venue against the manuscript's domain + claim_type +
  has_real_data + tier + page_count_estimate and returns
  {selected, rejected, all_scored} with full per-rule breakdowns.
• needs_tiebreak() flags top-2 ties (within 0.05 score); tiebreak_with_llm()
  resolves them via the same reviewer adapter chain documented in (4)
  above — Anthropic API → claude CLI → deterministic rule-based fallback.
• artifacts/d2_top_venue_adapters_acceptance.json::router_fixture_results
  records the 4-way distinct routing proof on the committed fixtures:
  CV → cvpr2024, NLP → acl_arr, ML → neurips2024, theory → arxiv_plain.
  Two different domain states route to two different venues; the
  paragraph-keyword preset is not enough to make all four collapse to
  one default.
• route_and_persist(selection_id, state) writes the decision to the
  manuscript_venue_selections table (joined on the agenda selection
  id). The D4 POST /api/manuscript/route/<selection_id> endpoint
  exposes this; GET /api/manuscript/route/<selection_id> re-fetches.

Known Failures

Both of these fail on origin/main as well and are unrelated to this PR's
surface area; the test files are unmodified by this PR (confirmable via
git diff origin/main -- tests/test_parallel_orchestration.py tests/test_validation_loop_metrics.py → empty diff).

• tests/test_validation_loop_metrics.py:: ValidationMetricParsingTests:: test_validation_benchmark_env_preserves_paper_grade_contract_budget
  — asserts DEEPGRAPH_BENCHMARK_MAX_EXAMPLES == "128" but observes "64".
  Benchmark env contract default drift on main.
• tests/test_parallel_orchestration.py:: AutoResearchSchedulingTests:: test_process_candidate_blocks_underspecified_verification
  — order-dependent: passes in the full pytest collection but fails in
  isolation. Pre-existing on main; auto_research scheduling state setup
  bleed. Leaving for a follow-up.

The third failure originally listed in the acceptance bundle's
known_baseline_failures (test_merge_candidate_context_helpers_exist) was
re-verified at PR HEAD and passes; the entry was removed from the
bundle to keep the evidence trail accurate.

Evidence JSON Cross-Reference

All six artifacts share the schema expected by the auto-acceptance scanner
(commit hash, sha256, test_command, test_summary, depends_on graph):

artifacts/agenda_loop_acceptance.json                  → #9
artifacts/manuscript_venue_routing_acceptance.json     → #11 (umbrella)
artifacts/d1_template_router_acceptance.json           → #12
artifacts/d2_top_venue_adapters_acceptance.json        → #13
artifacts/d3_format_linter_acceptance.json             → #14
artifacts/d4_manuscript_routing_api_acceptance.json    → #15

Each sub-evidence file references its own commit hash and the test command
that regenerates it.
