feat/0.7.0: dependency support (implies) + golden-tests - #71
Conversation
- ModelConstraints (model_encoder.py): intermediate layer shared by all solvers — conflicts as pairs, dependencies as implications - All solvers updated: Greedy, EnhancedGreedy, Z3, PuLP, OR-Tools, MaxSAT, MiniSAT — use encode_packages() for consistent encoding - CLI: --depends (-d pkg dep) and --explain flags - Web API: 'depends' field and 'explain' flag in /api/v1/maximize - golden_fixtures.py: apt-like and pip-like integration tests - test_solver_dependencies.py: unit tests for dep handling - 739 tests passing (from 721 in 0.6.1)

Route conflicts through add_conflict.
encode_packages bypasses ModelConstraints.add_conflict, so a declared self-conflict creates ("X", "X"). Z3, PuLP, OR-Tools, MaxSAT, and MiniSat encode this as ¬X, which incorrectly excludes X. Call constraints.add_conflict(pkg.name, conflict) and retain the final sort.

Restore respect_version_constraints and version-aware dependency checks
EnhancedGreedySolver remains a public export. Its previous constructor accepted respect_version_constraints, so callers that pass this argument now receive TypeError. The new encode_packages path also drops operators such as >=; solve() can therefore return a package together with a dependency version that violates its declared constraint. Restore the public option a

The remove strategy can delete a package that another selected package depends on.
Lines 67-69 remove r from selected and selected_set without checking dependents, and without adding r to blocked.
Trace libc, nginx(depends=["libc"]), xx(conflicts=["libc"]) with the default conflict_strategy="remove". If libc enters the solution as a dependency of nginx, and xx is processed later, libc is removed while nginx stays selected. The implication nginx -> libc is then violated. Because r is not blocked, a later iteration can also re-add libc next to xx, restoring the conflict.
Before you remove r, remove every selected package that transitively depends on r, and add r to blocked after removal. solve_with_weights needs the same change at Lines 135-143.

🎯 Functional Correctness | 🔴 Critical | 🏗️ Heavy lift
Both greedy solvers commit a package before they verify its dependency closure. Each site adds a dependency straight into the selected set. The main loop then skips that name, so the dependency's own conflict partners are never blocked and its own dependencies are never added. Each site also skips a dependency that is already blocked while the depending package stays selected. The result can violate a conflict pair or a pkg -> dep implication that Z3, PuLP, OR-Tools, and MiniSat enforce as hard constraints.
The fix is one shared selection step: build the transitive dependency closure of the candidate, reject the candidate if any closure member is blocked or if the closure creates a conflict with the current solution, then commit every closure member and block the conflict partners of each committed name.

Dependencies outside the candidate subset are dropped, so a package can be selected without its dependency.
temp_pkg_list contains only the already selected packages plus the current candidate. Line 141 skips every dependency clause whose target is not in that subset. The candidate is therefore accepted even when its dependency is never selectable.
Example: A depends on B, C declares a conflict with B, and weights are A=3.0, C=2.0, B=1.0. The loop accepts A (dependency clause dropped), accepts C, then rejects B because of the conflict with C. The returned set is [A, C], which violates the A→B implication that this PR adds. GreedySolver.solve_with_weights, the declared fallback, auto-includes dependencies, so the two paths return sets with different guarantees.
Build the candidate subset from the transitive dependency closure of the candidate, and reject the candidate when the closure is infeasible.

Use a monotone cardinality constraint for MiniSatSolver.solve
The dependency clauses make exact-cardinality feasibility non-monotone. For reachable --depends or API depends input with a → b and b → a, exact cardinality 1 is infeasible but cardinality 2 is feasible. The current search tests 1, then 0, and returns [] instead of ["a", "b"]. Use CardEnc.atleast for the binary search or enumerate cardinalities without assuming exact-cardinality monotonicity.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
The weighted feasibility check is vacuous, so conflicts and dependencies are not enforced.
The CNF built at lines 131-143 contains only conflict clauses [-a, -b] and implication clauses [-p, dep]. The all-false assignment satisfies every one of them. solver.solve() at line 149 therefore always returns True, and each candidate is accepted. The new dependency clauses at lines 139-143 and the conflict clauses at lines 135-137 never influence the result.
The pre-filter at line 122 only reads pkg.conflicts, so a conflict declared in the opposite direction is not caught. Example: C declares a conflict with B, weights are C=2.0 and B=1.0. C is selected, then B passes the vacuous check and is selected, and the returned set violates the conflict.
Force the selected packages and the candidate to true, as MaxSatSolver.solve_with_weights does. After that fix, this loop still needs the dependency-closure change described in the maxsat_solver.py comment, because line 141 drops dependency clauses whose target is outside the subset.
🐛 Proposed fix to force the candidate and the selected set

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

the feasibility check in the solver loop so the existing selected packages and
the current pkg are constrained true before calling solver.solve(), rather than
solving the unconstrained CNF. Preserve the conflict and dependency clauses, and
ensure dependency closure includes dependencies whose targets fall outside the

Validate depends before building dep_map.
If "depends": null, the loop raises outside the solver error handler, so Flask returns HTTP 500. If a pair contains a non-string package name, such as [[], "dep"], dep_map.setdefault raises TypeError. Update validate_maximize_payload to require a list of two package-name strings for every dependency pair and return HTTP 400 for invalid input. Add endpoint tests for both payloads.
