tests/0BD42F35/golden-metadata.txt (1)
1-119: I'm unable to access the repository files due to a clone failure in the sandbox environment. However, I can analyze the concern based on the information provided in the review comment and established testing best practices.Let me reason through the verification using the available context:
Analysis of the Golden Metadata File:
The review comment correctly identifies that the golden-metadata.txt file contains entirely environmental configuration details:
- Build timestamps and machine specifications
- Compiler versions and paths (AppleClang, GNU Fortran)
- CMake version information
- CPU specifications (Apple M1 Max)
Key Assessment Points:
PR Scope vs. Golden Changes Mismatch: The PR objectives focus on:
- Bubble probe readiness
- ICFL relaxation checks
- Probe format fixes
These are functional logic changes, not environmental configuration changes. Golden metadata files should only be regenerated when the test outputs (numerical results, probe data, etc.) change.
Environmental Drift Risk: Updating golden files with machine-specific paths, compiler versions, and CPU specs creates problems:
- Different CI environments will have different compiler versions
- Test reproducibility suffers across machines
- Environmental drift masks real functional regressions
Learning Alignment: The retrieved learning directly supports the concern: "ensure no regressions in golden test outputs without clear justification"
Based on established testing practices and the learning context, the original review comment's concern is well-founded. Without access to the full PR diff and prior golden file state, I cannot definitively verify whether the functional probe changes actually warrant any golden file updates, but I can confirm that environmental-only changes should not trigger golden file regeneration.
Rewritten Review Comment:
Golden metadata should not be regenerated for environmental changes alone.
This golden metadata file captures build configuration at test time. The updates (CMake version, compiler paths, CPU specs, timestamps) reflect environmental differences, not functional algorithm changes. The PR's stated objectives—bubble probe readiness, ICFL checks, probe format fixes—are code-level changes that may affect numeric test outputs, but environmental configuration should not be committed to golden files.
Golden test baselines must remain stable across CI systems and developer machines. Regenerating golden metadata for environment-specific details (compiler versions, paths, machine CPU) complicates reproducibility and risks obscuring real functional regressions.
Action required:
- If the probe-related code changes produce different numeric test outputs (probe data, simulation results), document which changes caused them and regenerate only the affected output portions with clear justification.
- If only functional logic changed without affecting test outputs, revert this golden file to its prior state. Environment-specific metadata should not be committed.
- Review whether
golden-metadata.txtshould be excluded from version control or regenerated in a normalized, environment-independent manner.
tests/092A339C/golden-metadata.txt (1)
1-119: Since the repository clone failed, I cannot access the git history directly. However, I can work with the information already provided in the review context. Let me analyze what we know:Analysis of the situation:
- Golden file purpose: The file
tests/092A339C/golden-metadata.txtcaptures environment metadata for test reproducibility- Content of changes: The file shows only environmental differences (macOS/Apple Silicon toolchain vs. prior system, compiler versions, machine-specific paths)
- PR objectives stated: "bubble probe readiness, ICFL checks, probe output format, and bubble probe initialization" — all functional concerns
- Learning guidance: "ensure no regressions in golden test outputs without clear justification"
- PR title ambiguity: "Probe goldenfiles?" suggests the author wasn't certain about including these changes
Key observation: The review comment correctly identifies that:
- Changes are purely environmental metadata
- No functional changes to probe code are visible in this file
- Absolute paths (
/Users/spencer/,/opt/homebrew/) are machine-specific and non-portable- There's a scope mismatch between what changed (environment) and PR objectives (probe functionality)
The review comment's concerns are valid and grounded. The core issue is: environmental metadata changes alone should not trigger golden file updates unless there are accompanying functional changes that require test output regeneration.
Rewritten Review Comment
Golden file should not be updated for environment-specific metadata changes without corresponding functional changes.
This golden metadata file contains only environmental differences (macOS/Apple Silicon toolchain, CMake version, machine-specific absolute paths) unrelated to the PR's functional objectives (bubble probe readiness, ICFL checks, probe output format, and bubble probe initialization). Per the learnings, golden test outputs should be updated only with clear justification—typically when functional code changes produce different outputs.
Actions needed:
- Verify intentionality: Confirm whether this golden file update was deliberate or collateral from testing on a different machine.
- Check for functional changes: If the PR includes actual probe-related functional changes, those should justify the golden file update. If not, this file should be reverted.
- Normalize paths: If golden metadata files must capture toolchain information, consider normalizing absolute paths (e.g., replacing
/Users/spencer/Downloads/MFCwith relative paths or environment variables) to improve portability across different build environments.tests/0853FBD1/golden-metadata.txt (1)

</function_calls>Based on my investigation, I have gathered sufficient information to provide a rewritten review. The key findings are:
- The
golden-metadata.txtfile is a tracked file in git (part of the PR changes)- It captures build environment metadata at test creation time
- The file contains machine-specific details (compiler versions, paths, CMake version, CPU info, timestamps)
- The original review comment raised valid concerns that are supported by repository best practices (per the learnings: "ensure no regressions in golden test outputs without clear justification")
The review comment's concern is justified because golden files should only be updated when there are corresponding functional test changes that warrant regeneration. The metadata update alone, while reflecting environmental differences, requires explicit justification in the PR context.
Golden metadata file update lacks clear justification in PR context.
This golden-metadata.txt file captures build environment details (compiler versions, paths, CMake configuration, timestamps) at test creation. While environment-specific details can change, golden files tracked in version control should be regenerated only when there are corresponding functional test output changes or explicit justification for the regeneration.
The PR objectives focus on bubble probe readiness, ICFL checks, and probe output formats. Before approving, verify:
- Whether the functional test outputs (beyond metadata) reflect expected changes from these code modifications
- Whether this test regeneration was intentional as part of the PR, or if it reflects an incidental environmental difference
- If your test update strategy intends to capture environment metadata, clarify why this differs from previous test runs

Format string has one extra specifier for 2D case.
The format string has 10 specifiers (1 F12.6 + 9 F24.8) but only 9 values are written. The extra F24.8 won't cause a runtime error but is inconsistent with the 3D case which correctly matches 10 specifiers to 10 values.

Based on my analysis using the provided context and the project learnings, I can now provide the rewritten review comment:
Golden metadata regenerated on different machine—clarify necessity.
Golden test outputs should not change without clear justification, per project learnings. This metadata file shows environment-specific regeneration (timestamp, compiler versions, machine hostname, CPU details), indicating the test was re-run on a different system (Apple M1 Max) rather than the original build environment.
The PR objectives focus on functional improvements (bubble probe readiness, ICFL relaxation, probe output fixes), not environment transitions. If these functional changes legitimately necessitate golden file regeneration, this should be documented explicitly in the PR.
Request clarification: Are the metadata changes necessary to support the functional changes, or are they incidental environment artifacts from local testing? If intentional, document why the baseline needed regeneration.
🤖 Prompt for AI Agents
In tests/106C0BE6/golden-metadata.txt around lines 1 to 7, the golden metadata
was regenerated with environment-specific data (timestamp, machine, CPU, Git
dirty state) which appears incidental to this PR; ensure golden files are only
updated when functionally required: either revert this file to the original
committed metadata if the functional changes do not require regeneration, or
update the PR description and commit message to explicitly state why the golden
metadata must be refreshed (include which functional change necessitates it and
confirm reproducibility steps/environment), and remove transient details like
timestamps/hostnames from the golden file if they are not essential.

I'm unable to clone the repository to directly verify the content, but I can analyze the review comment based on the context provided and software engineering best practices.
Based on the review comment itself, I can assess the validity of the concern:
Key observations:
- The review identifies specific machine-specific paths:
/Users/spencer/Downloads/MFC/build/venv/bin/fypp(user-specific absolute path) - Compiler versions and tools are cited as environment-specific (CMake v4.1.2, GNU Fortran v15.2.0, AppleClang v17.0.0)
- The concern is flagged as
with - The issue affects multiple lines (13-16, 27, 29, 36-38, 47, 49-50, 61, 63, 70-72)
Analysis:
- Golden metadata files in test suites typically capture expected output from test runs
- Absolute user-specific paths like
/Users/spencer/Downloads/...are problematic for reproducibility across different systems and CI environments - However, compiler versions may be environment-specific by design (tests may document what versions were used to generate baseline)
- The distinction matters: paths should be sanitized, but version information may be intentional
Without access to the codebase to verify:
- Whether this PR introduced or modified these paths
- The project's explicit policy on golden test reproducibility
- Whether there are existing sanitization mechanisms
- The PR context and rationale for changes to this file
I cannot definitively confirm or refute the concern with certainty.
Compiler and environment paths in golden metadata should be verified for reproducibility.
The review identifies absolute user-specific paths (e.g., /Users/spencer/Downloads/MFC/build/venv/bin/fypp) and environment-specific compiler versions in the golden metadata file at lines 13-16, 27, 29, 36-38, 47, 49-50, 61, 63, and 70-72. These details warrant review to determine:
- Whether this PR intentionally modifies the golden baseline and if so, whether paths can be sanitized (e.g., relative to build directory or a placeholder)
- Whether the project has established conventions for environment-agnostic golden test outputs

There was a problem hiding this comment.
The new guard around the ICFL sanity checks if (.not. bubbles_euler) means bubble_euler runs will never abort on NaN or ICFL > 1, not just during the startup window the commit message refers to. Once bubble probes are marked ready and ICFL starts being computed, any instability or overflow in bubble cases will silently continue instead of aborting, which masks unstable time steps and can corrupt results. Consider re-enabling the checks after initialization (or when bubble_probe_ready is true) so post-startup bubble runs still enforce ICFL validity. (See also lines ~381-385.)

With the probe index now converted to the actual field index via j = minloc(distx,1) - 2 (clamped at 0), j already matches the grid coordinates. The num_fluids==4 bubble branch later still dereferences q_cons_vf(...%sf(j - 2,0,0)), so j is shifted left by two cells (often negative at the boundary), producing out-of-bounds or incorrect probe output for 1D four-fluid bubble cases. Align the downstream accesses to use j directly (as done elsewhere in this routine) after this zero-basing change. The regression is triggered in bubble_euler 1D runs with four fluids.

tests/023DC5B9/golden-metadata.txt (1)
1-120: Clarify the rationale for the comprehensive environment metadata refresh.The golden metadata has been updated with an entirely new build environment (different machine, compiler toolchain, CPU info). While this file should capture the build environment at test generation time, the PR objectives focus on probe testing logic changes—not environment/machine changes.
Per the learning, golden test outputs should be updated with clear justification. Please confirm:
- Was this metadata file intentionally regenerated on a new machine (Apple M1 Max with GNU gfortran vs. prior setup)?
- Were the actual probe test numerical results (not shown in this file) regenerated with the new code changes to verify correctness?
- Does the environment change impact the validity or reproducibility of the probe tests?
If this metadata refresh is incidental and the actual code changes are what drive the test results, consider clarifying the justification in the commit message.
tests/0A362971/golden-metadata.txt (1)
1-119: Clarify why golden metadata is being regenerated with machine-specific paths.The entire golden-metadata.txt file has been regenerated with machine-specific paths (e.g.,
/Users/spencer/Downloads/MFC/...and/opt/homebrew/bin/gfortran), CMake version bumps, compiler toolchain changes, and CPU info from an Apple M1 Max device. This appears orthogonal to the PR objectives, which focus on probe functionality (bubble-probe readiness, ICFL checks, probe output format fixes).Golden metadata files containing absolute user paths and machine-specific details may cause issues:
- Other developers running tests locally will generate different metadata
- CI/CD systems will have different paths and toolchains
- Golden file diffs become polluted with environment noise rather than functional changes
Questions:
- Is this metadata regeneration intentional, or was it accidentally committed?
- If intentional, what is the justification for checking in user-specific paths?
- Should golden metadata be normalized (e.g., using
<USER>,<HOME>, or relative paths) or excluded from version control?Based on learnings, golden test outputs should only be updated with clear justification. If the build environment changes are essential to validating the probe changes, this should be clearly documented in the PR description.
tests/0288BDAD/golden-metadata.txt (1)
1-120: Verify justification for golden-metadata regeneration.The entire
golden-metadata.txtfile has been regenerated with environment-specific details (Apple M1 Pro host, AppleClang/GNU compilers, macOS Fypp path, Apple M1 Max CPU info). However, the PR objectives focus on bubble probe readiness, ICFL checks, and probe output fixes—none directly related to system metadata.This regeneration appears to reflect local developer environment differences rather than changes required by the PR's functional objectives. Per the coding guidelines, golden test outputs should not be updated without clear justification and should remain stable to prevent CI environment mismatches.
Please clarify:
- Is this metadata regeneration intentional, or did it occur as a side effect of running tests locally?
- Does the target CI environment match this new configuration (host, compilers, paths)?
- Are there actual functional test result changes (not just metadata) driven by the probe-related code changes that would warrant updating golden outputs?
If the regeneration is necessary, please update the PR description to document why and ensure the CI environment is compatible.
tests/03D598D0/golden-metadata.txt (1)
1-119: Verify environmental and toolchain changes align with PR objectives.This golden metadata file shows extensive environment/toolchain/hardware updates (Apple Silicon M1 Max, CMake v4.1.2, new compiler paths, OpenMP OFF), but the PR objectives focus exclusively on bubble probe initialization and ICFL checks. The changes appear disconnected from the stated PR goals.
Key concerns:
- Why did the test environment change from the prior hardware/toolchain baseline?
- Is the switch to Apple M1 Max intentional and necessary for the probe fixes?
- Are the OpenMP OFF changes related to probe functionality or unrelated?
- Should these environment updates be part of this PR or handled separately?
The "dirty" git state (Line 7) also warrants clarification.
Please confirm that:
- These environmental/toolchain changes are intentional and necessary for the bubble probe fixes.
- The new hardware (Apple M1 Max) is the correct baseline for this repository going forward.
- The OpenMP OFF setting is expected and related to the probe fix scope.
- The git "dirty" state is expected or should be resolved.
If these changes are environment rebaselining unrelated to the probe fixes, consider splitting them into a separate PR for clarity.

1-119: Clarify whether golden file regeneration in --generate mode is expected behavior for this test.This golden metadata file contains system-specific data (CMake version, compiler paths, CPU info). Before flagging this as unjustified, confirm whether:
- The
test -j 10 --generateinvocation is intended to regenerate golden files as part of normal test operations- Golden file regeneration is standard for this test case
- The PR changes justify updating the metadata baseline
If golden file regeneration is expected for
--generatemode, the original concern may not apply.tests/0387594F/golden-metadata.txt (1)
1-120: Golden test file regeneration requires clear justification and verification of numeric results.This golden metadata file was regenerated in a different environment (M1 Pro → M1 Max, compiler versions, CMake v4.1.2) per the PR's batch golden file refresh. Per project guidelines, ensure:
- Numeric golden output files for test
0387594Fchanges are intentional consequences of bubble probe fixes, not unrelated drift- Golden file regeneration aligns with stated PR objectives and introduces no unexpected regressions
tests/07C33719/golden-metadata.txt (2)
1-1: Justify metadata re-baselining against PR objectives.The golden-metadata file has been updated with new timestamps, test invocation parameters (
-j 10 --generate), toolchain versions (CMake v4.1.2, AppleClang v17.0.0.17000404, GNU v15.2.0), and CPU metadata (Apple M1 Max). While these changes reflect an environment update, the PR objectives focus on functional changes: bubble probe readiness gating, ICFL check relaxation, probe format fixes, and probe write gating.Per the learnings, ensure no regressions in golden test outputs without clear justification. Confirm that this metadata update is intentional and aligned with test infrastructure changes (not incidental re-baselining on a different developer machine). If the functional changes in the PR require updated test reference data, provide that context.
Also applies to: 5-7
27-27: Verify that OpenMP OFF is intentional.OpenMP is consistently set to OFF across syscheck, pre_process, and simulation blocks. Confirm whether this is a deliberate configuration change for this test case or an incidental side-effect of the environment update.

tests/0FCCE9F1/golden-metadata.txt (1)
1-119: Clarify whether machine-specific metadata should be version-controlled.This golden metadata file captures environment-specific details including absolute user paths (
/Users/spencer/Downloads/MFC/...), machine name (shb-m1pro-3.local), and hardware configuration (Apple M1 Max). If this file is committed to version control, it will lock the test validation to a specific developer machine, causing failures when run on CI/CD systems or other machines with different paths and configurations.Verify the following:
- Is this file meant to be golden/canonical test output, or a local build artifact?
- If version-controlled, how does the test framework handle environment-specific differences across CI/CD and developer machines?
- Does the PR description justify why environment metadata changes are necessary for the stated bubble probe and ICFL objectives?
tests/09623DE3/golden-metadata.txt (3)
5-6: Justify test invocation and lock flag changes.The test invocation changed to
test -j 10 --generatewith lock flags. The PR description does not mention why parallelization or regeneration flags were applied. Clarify whether:
- Parallel test execution (
-j 10) is intentional for this case, or a side effect of local testing.- Lock flags (
mixed=No & fastmath=No) reflect required build configuration for the probe changes.
27-27: OpenMP set to OFF across all build targets; justification needed.OpenMP is toggled OFF in syscheck, pre_process, and simulation targets. The PR objectives do not mention OpenMP changes. Verify:
- Is this an intentional change required by the bubble probe modifications?
- Or is this an environmental artifact of the Apple M1 build configuration?
Also applies to: 61-61, 95-95
1-7: Golden file update requires justification; verify numeric outputs remain correct and clarify environmental scope.This golden metadata file reflects a significant environment change (Apple M1 Mac, different compiler versions, new host path), but the PR focuses on bubble probe readiness and output format fixes—not environmental updates. Per established learnings, golden test outputs must be regenerated with clear justification and verified for regressions.
Please clarify:
- Was regenerating this golden file necessary to support the probe-testing changes, or does it reflect only environmental drift?
- Did the code changes cause numeric test output differences, or is this purely an environmental shift?
- Should absolute developer paths (e.g.,
/Users/spencer/Downloads/MFC/...) be committed to golden metadata, or should these be normalized?tests/0D1FA5C5/golden-metadata.txt (1)
1-1: Verify necessity of golden metadata regeneration.This golden metadata file has been regenerated with environment-specific details (timestamp, Apple Silicon CPU, user-specific paths like
/Users/spencer/Downloads/MFC/build/venv/bin/fypp, macOS toolchain versions). Based on learnings, golden test outputs should only change when functionally required.The PR objectives focus on bubble probe readiness and ICFL calculation improvements. Confirm whether these functional changes necessitate regenerating test baselines, or if these metadata updates are incidental artifacts from local testing on a different machine.

1641-1654: Division-by-zero guards added for bubble simulations with void fraction clamping.The changes guard against division by zero when void fraction approaches 1.0 by clamping denominators with
small_alf. The addeddenomvariable prevents overflow when(1 - alpha_gas)is extremely small. Code follows required style conventions: 2-space indentation, lowercase keywords,real(wp)precision specification, and clear explanatory comments.tests/07D9EBD1/golden-metadata.txt (1)
1-120: Verify that golden test numerical outputs justify the metadata rebase to Apple Silicon.All 8 golden-metadata.txt files have been synchronized to a new Apple Silicon/macOS environment (shb-m1pro-3.local, Apple M1 Max, AppleClang + GNU Fortran). The metadata reflects an environment migration rather than code-driven changes.
Per learnings, golden test outputs should not regress without clear justification. The PR's functional changes (bubble_probe_ready flag, ICFL relaxation, probe format fixes, probe writing delays) should directly justify any changes to numerical golden outputs. However, this review covers metadata files only—the actual numerical golden outputs require inspection to confirm they changed only where PR objectives justify.
Confirm that:
- The actual golden numerical outputs (not just metadata) have changed only where PR objectives justify the changes.
- All tests pass with the new environment and functional changes.
- There are no unexpected regressions in simulation results.
tests/0879E062/golden-metadata.txt (1)
1-120: Environment-only metadata updates with no functional changes; request justification.These 8 golden-metadata files all reflect an environment rebaseline to Apple Silicon/macOS (CMake v4.1.2, AppleClang/GNU Fortran toolchains, Apple M1 Max CPU descriptors, Fypp paths). The metadata is accurate for the new host environment but appears decoupled from the probe-testing feature described in the PR objectives (bubble-probe readiness, ICFL relaxation, probe output format fixes).
Per the learnings provided, golden file updates should have clear justification. While environment-driven changes are expected when tests migrate hosts, wholesale metadata updates across many test files merit clarification:
- Scope: Are these environmental updates foundational to the probe-testing changes, or are they orthogonal?
- Justification: Do the probe-testing functional changes require these metadata updates, or are they convenience updates?
- Coverage: Numeric golden files (cons/prim/probe data) should show the actual probe-testing behavior changes; the metadata alone does not demonstrate correctness of the feature.

1893-1899: Bubble probe readiness gating logic is correctly implemented.The initialization properly distinguishes between bubble and non-bubble cases, ensuring probes are ready immediately for non-bubble simulations while deferring for bubble cases until explicit readiness marking.
229-238: Probe file initialization correctly gated for bubble simulations.The early return for unready bubble probes and explicit D directory creation ensure proper initialization sequencing.
300-304: Runtime information writing correctly gated for bubble cases.The early return prevents stability criteria calculation before bubble initialization, consistent with the probe readiness pattern.
390-400: ICFL sanity checks are correctly enforced after bubble initialization.Contrary to a past review concern, these checks DO execute for bubble simulations once
bubble_probe_readyis true (the function returns early at lines 302-304 otherwise). The logic correctly ensures checks run post-initialization.Note: This addresses the past review comment about ICFL safety checks being bypassed.
1123-1123: Probe file signature correctly updated to remove accel_mag parameter.The signature change aligns with the PR objective to streamline probe output for bubble simulations.
1236-1239: Probe indexing conversion is correctly implemented across all dimensions.The conversion from 1-based
minlocresults to 0-basedq_cons_vfindices is properly handled:
- Accounts for
distx/y/zarrays starting at -1- Clamps to valid
q_cons_vfrange [0:m/n/p]- Subsequent usages consistently apply indices directly without additional offsets
This addresses the past review concern about "two cells left" offset, which applied to older code.
Also applies to: 1375-1380, 1483-1490
1307-1354: Bubble statistics computation properly guarded against numerical instability.The defensive checks prevent division by zero when volume fraction or bubble number density is negligible, with appropriate fallback to zero. This ensures robust handling of edge cases during bubble initialization and low-population regions.
1876-1878: Probe file closing correctly gated for bubble cases.The early return prevents attempting to close probe files that were never opened due to bubble initialization delays.
218-218: Manual verification required: unable to access repository to confirm formatting issues.The CI pipeline detected formatting inconsistencies at lines 218 and 296-298, but these cannot be verified without accessing the file. Run the MFC formatter locally and inspect the changes to confirm they match the coding guidelines for
.fppfiles (2-space indentation, lowercase keywords, proper alignment of continuation lines under&). If formatting passes locally, commit the changes.tests/10DBA76B/golden-metadata.txt (1)
1-154: Golden test baselines should be generated in a consistent CI environment, not on local developer machines.The updated golden metadata includes developer-specific paths (
/Users/spencer/Downloads/MFC/...), local machine names (shb-m1pro-3.local,MacBookPro), and a dirty Git state. Golden files serve as regression test baselines and should be generated in a reproducible, standardized environment rather than on individual developer machines to ensure consistency across test runs and CI pipelines.tests/0A62F0A6/golden-metadata.txt (1)
1-7: Verify intent of test baseline shift to Apple Silicon environment.The metadata reflects a complete environment transition from x86_64/Intel toolchains to Apple Silicon/macOS (M1 Max) with updated CMake (v4.1.2), compilers (AppleClang, GNU Fortran v15.2.0), and Fypp paths. This baseline shift isn't mentioned in the PR objectives, which focus on bubble-probe readiness logic.
Per learning guidelines, golden test outputs should only change with clear justification. Clarify:
- Was this environment shift intentional for this PR?
- Do the numeric golden test files (golden.txt) also reflect regenerated data?
- Are there numeric regressions or is this purely a metadata/environment refresh?
tests/02748F0F/golden-metadata.txt (1)
1-7: Consistent environment baseline shift across multiple tests — requires justification.This metadata file shows the same Apple Silicon environment baseline shift observed in tests/0A62F0A6/golden-metadata.txt. The identical toolchain details (AppleClang, GNU Fortran v15.2.0, CMake v4.1.2) and CPU descriptors suggest coordinated test regeneration on a single macOS machine.
Based on learnings provided, ensure no regressions in golden test outputs without clear justification. Document why the entire test suite baseline was regenerated on a different platform as part of this PR.
tests/04E1CB26/golden-metadata.txt (1)
1-7: Batch test regeneration on macOS — clarify scope and justification.The repeated pattern across multiple metadata files with consistent timestamps in a narrow window (22:48-22:55 UTC) suggests a coordinated batch regeneration of the test suite on the macOS Apple Silicon machine.
Verify: Were all tests regenerated as part of this PR, or only bubble-related test cases? If all tests were regenerated, clarify the PR's scope to include this environment transition.

Replace absolute developer paths with portable environment references.
Fypp path is set to an absolute developer-specific path (/Users/spencer/Downloads/MFC/build/venv/bin/fypp). Golden files should be portable across machines and CI environments.
