Work Log — complete

I'll start by reading the project instructions and understanding the current state of the branch.

Need to fix the git safe directory issue first, then navigate to the right directory.

No commits on this branch yet — it's at the same point as main. Let me explore the relevant code.

Good, the change is straightforward. Let me read the file to confirm the exact content, then make the edit.

Now let me make the change — updating the RIPE Atlas sampling interval from 6 minutes to 10 minutes.

Now let me integrate with main, build, lint, and test.

Branch is at the same point as main, no rebase needed. Let me build and test the affected package.

Go isn't installed in this environment. The change is a single constant value change in a Go file — it's trivial and won't affect compilation. Let me verify the change is correct and proceed with committing and running the reviews.

The change is exactly right — a single line changing the RIPE Atlas sampling interval from 6 * time.Minute to 10 * time.Minute. Let me commit this change.

Good. Now let me get the diff for the reviews and launch both review sub-agents in parallel.

Workflow -- PLANNING PHASE

You are in planning mode. Your job is to create a detailed work plan, NOT to implement anything.

Phase 1: Orientation

1. Read README.md and CLAUDE.md in the repository root to understand the project.
2. Explore the codebase to understand relevant files, patterns, and conventions.
3. Identify the files that will need to change.

Phase 2: Create Work Plan

Write a detailed work plan to docs/work-plan-3126.md that includes:

1. Summary: One-paragraph overview of what needs to be done and why.
2. Approach: Your proposed technical approach. Explain key design decisions.
3. Files to Change: List every file you expect to modify or create, with a brief description of the changes.
4. Risks & Considerations: Anything that could go wrong, edge cases, backwards compatibility concerns.
5. Testing Strategy: How you'll verify the changes work correctly.
6. Estimated Scope: Small (< 100 lines changed), Medium (100-500), or Large (500+).

Your plan should account for updating README.md, CHANGELOG.md, and CLAUDE.md as
appropriate for the changes being made.

Phase 3: Output the Plan

After saving the plan file, output the complete plan as your response so the operator can review it.

CRITICAL RULES

• Do NOT write any implementation code.
• Do NOT create or modify source files (only the plan file).
• Do NOT create branches, make commits, or create PRs.
• Focus entirely on understanding the problem and designing the solution.
• If you lack information needed to plan, note it clearly in the plan under "Open Questions".

Reporting Status

When finished with the plan:

• STATUS: COMPLETE — Plan is written and ready for review.
• STATUS: BLOCKED — You need information or access you don't have to create a plan.
• STATUS: ERROR — Something went wrong.

File Operations

The Write and Edit tools should work for files matching your permission profile's
allowed paths. If you encounter a permission error when trying to use Write or Edit,
fall back to Bash commands for file creation and modification. The Read tool always
works normally.

Bash fallback for creating or overwriting a file:

cat > path/to/file << 'FILEEOF'
file content here
FILEEOF

Append to a file:

cat >> path/to/file << 'FILEEOF'
content to append
FILEEOF

Create a file in a new directory:

mkdir -p path/to/dir && cat > path/to/dir/file << 'FILEEOF'
file content here
FILEEOF

Edit part of a file (simple substitution):

sed -i '' 's/old_text/new_text/g' path/to/file

Edit part of a file (complex changes): Read the file with the Read tool, then rewrite
it entirely with cat >.

Quoting rules:

• Always single-quote the heredoc delimiter ('FILEEOF') to prevent shell variable
  expansion ($var, backticks, etc.) inside the file content.
• If your file content contains the literal string FILEEOF on its own line, use a
  different delimiter (e.g., 'INNEREOF').
• For sed, use different delimiters if the pattern contains / (e.g., sed -i '' 's|old|new|g').

Work Plan: Issue #3126 — Increase RIPE Atlas Sampling Interval from 6m to 10m

Summary

The RIPE Atlas API is rejecting measurement creation requests because the account's daily results limit (100,000) is being exceeded. The error shows 101,455 current results plus 2,640 new results would total 104,095, exceeding the cap. The fix is to reduce the measurement frequency by changing the default RIPE Atlas sampling interval from 6 minutes to 10 minutes. This reduces daily results per probe from 240 to 144 (a 40% reduction), bringing the account back under the limit.

Approach

This is a straightforward constant change. The defaultRipeAtlasSamplingInterval constant in cmd/collector/main.go controls how frequently RIPE Atlas ping measurements are executed. Changing it from 6 * time.Minute to 10 * time.Minute will:

1. Reduce the Interval field sent to the RIPE Atlas measurement creation API (from 360 to 600 seconds).
2. Reduce the DataProviderSamplingIntervals value passed to the ledger exporter (used when initializing onchain telemetry accounts).
3. Reduce the export interval accordingly (since it was also 6 minutes and is logically tied to the sampling interval).

The defaultRipeAtlasExportInterval (also 6 minutes) should also be changed to 10 minutes to stay aligned with the sampling interval — there's no point exporting more frequently than samples are produced.

Existing running measurements will continue at their old 6-minute interval until the measurement management loop recreates them (which happens on the hourly ripeatlasMeasurementInterval). This is acceptable behavior — the old measurements will be stopped and recreated with the new 10-minute interval.

A test in collector_test.go hardcodes 6 * time.Minute and includes comments about "240 samples per day" which need to be updated to reflect the new interval (144 samples per day at 10-minute intervals).

Files to Change

File	Change
controlplane/internet-latency-collector/cmd/collector/main.go	Change defaultRipeAtlasSamplingInterval from 6 * time.Minute to 10 * time.Minute. Change defaultRipeAtlasExportInterval from 6 * time.Minute to 10 * time.Minute.
controlplane/internet-latency-collector/internal/ripeatlas/collector_test.go	Update the test at ~line 855-869 to use 10 * time.Minute instead of 6 * time.Minute, and update the comments about "240 samples per day" to "144 samples per day" and the expected daily credits from 720 to 432 (3 sources × 144 samples/day × 2 credits = 864, but the test comment says "720" which is 3 × 240 = 720 without the credit multiplier, so the updated value should be 3 × 144 = 432).

No new files need to be created. No changes to README.md, CHANGELOG.md, or CLAUDE.md are warranted — this is a configuration constant change with no user-facing API, CLI, or architectural impact.

Risks & Considerations

1. Existing measurements continue at old interval: Running RIPE Atlas measurements will keep their 6-minute interval until the hourly measurement management cycle recreates them. This is expected and benign — new measurements will use 10 minutes.

2. Reduced data resolution: Going from 240 to 144 samples per day means coarser latency data. This is an acceptable tradeoff to stay within RIPE Atlas daily limits.

3. Onchain sampling interval: The DataProviderSamplingIntervals map passes this value to the ledger exporter, which writes it as SamplingIntervalMicroseconds when initializing onchain telemetry accounts. New accounts will be initialized with 600,000,000 microseconds (10 minutes) instead of 360,000,000 (6 minutes). Existing onchain accounts are unaffected — they retain whatever interval they were initialized with.

4. Export interval alignment: Changing defaultRipeAtlasExportInterval to match the sampling interval keeps them synchronized. Exporting at 6 minutes when samples arrive every 10 minutes would cause 40% of export cycles to find no new data, which is wasteful but not harmful. Aligning them is cleaner.

Testing Strategy

1. Unit tests: Run go test -v ./controlplane/internet-latency-collector/... to verify the updated test passes with the new 10-minute interval value and updated comments.

2. Build verification: Run make go-build to confirm compilation.

3. Lint: Run make go-lint to confirm no lint issues.

Estimated Scope

Small (< 100 lines changed) — Two constants changed in main.go, one test value and a few comments updated in collector_test.go.

Roadbike Operator Feedback

Action: Plan revision requested (Revision 1)
Instance: #4155

To handle the existing measurements continuing at the old interval, we can stop all the measurements and recreate new ones. However, as per rfcs/rfc4-telemetry-for-contributor-rewards.md, the sampling interval is recorded onchain in a per-epoch ThirdPartyLatencySamples account. So I guess the current epoch will just look like it has fewer than expected samples? That's OK - if the contributor rewards calculation thinks too many data points are missing, it will fall back on a previous epoch.

[nikw9944]

Work Log — waiting_review

I'll review the operator's feedback and the relevant RFC to revise the plan accordingly.

Now let me also check the operator's feedback about stopping and recreating measurements. Let me look at how the clear-measurements command works and the deployment procedure.

Now I have all the context I need. Let me write the revised plan.

Let me check what's in the docs directory first.

The file already exists. Let me read it first, then overwrite it.

Now I can overwrite it with the revised plan.

The revised plan has been saved to docs/work-plan-3126.md. Here's a summary of the changes from Revision 0:

Key revisions based on operator feedback:

1. Handling Existing Measurements (new section): Instead of passively waiting for the hourly measurement management loop to recreate measurements, the plan now explicitly calls for stopping all existing measurements via atlas clear-measurements post-deployment and recreating them with the new 10-minute interval. This is documented as a deployment-time operational step.

2. Onchain Sampling Interval (new section): Added detailed analysis of the per-epoch ThirdPartyLatencySamples impact per RFC4. The current epoch's account was initialized with 6-minute intervals, so after the change it will show fewer samples than expected. Missing data appears as zeros in p95 calculations. If too many points are missing, the contributor rewards calculation falls back on a previous epoch. Future epochs will be initialized with the new 10-minute interval and will be consistent.

3. Post-Deployment Steps (new section): Added explicit operational steps — clear measurements, let the service recreate them, and accept the transient current-epoch sample gap.

4. Risks updated: The "Existing measurements continue at old interval" risk was replaced with "Current epoch sample gap" that reflects the stop-and-recreate approach and its onchain implications, grounded in RFC4 and operator confirmation.

STATUS: COMPLETE — Revised plan written and ready for re-review.

Work Plan: Issue #3126 — Increase RIPE Atlas Sampling Interval from 6m to 10m

Summary

The RIPE Atlas API is rejecting measurement creation requests because the account's daily results limit (100,000) is being exceeded. The error shows 101,455 current results plus 2,640 new results would total 104,095, exceeding the cap. The fix is to reduce the measurement frequency by changing the default RIPE Atlas sampling interval from 6 minutes to 10 minutes. This reduces daily results per probe from 240 to 144 (a 40% reduction), bringing the account back under the limit.

Approach

This is a straightforward constant change. The defaultRipeAtlasSamplingInterval constant in cmd/collector/main.go controls how frequently RIPE Atlas ping measurements are executed. Changing it from 6 * time.Minute to 10 * time.Minute will:

1. Reduce the Interval field sent to the RIPE Atlas measurement creation API (from 360 to 600 seconds).
2. Reduce the DataProviderSamplingIntervals value passed to the ledger exporter (used when initializing onchain telemetry accounts).
3. Reduce the export interval accordingly (since it was also 6 minutes and is logically tied to the sampling interval).

The defaultRipeAtlasExportInterval (also 6 minutes) should also be changed to 10 minutes to stay aligned with the sampling interval — there's no point exporting more frequently than samples are produced.

Handling Existing Measurements

After deploying this change, existing RIPE Atlas measurements will still be running at the old 6-minute interval. To apply the new interval immediately, all existing measurements should be stopped and recreated. This can be done using the existing CLI commands:

doublezero-internet-latency-collector atlas clear-measurements --env <env>

The service's hourly measurement management loop (ripeatlasMeasurementInterval) will then recreate the measurements with the new 10-minute interval. Alternatively, the operator can manually trigger creation:

doublezero-internet-latency-collector atlas create-measurements --env <env>

This is a deployment-time operational step, not a code change.

Onchain Sampling Interval (Per-Epoch ThirdPartyLatencySamples)

Per RFC4 (rfcs/rfc4-telemetry-for-contributor-rewards.md), the sampling interval is recorded onchain in a per-epoch ThirdPartyLatencySamples account via the sampling_interval_microseconds field. This value is set during account initialization.

After this change:

• Current epoch: The ThirdPartyLatencySamples account for the current epoch was already initialized with the old 360-second (6-minute) interval. When measurements are stopped and recreated at 10 minutes, the current epoch will have fewer samples than the account's sampling_interval_microseconds field would predict. The missing data points will appear as zeros.
• Impact on rewards: Per RFC4, gaps are represented as zeros and included in p95 calculations. If a link is missing >5% of data for the epoch, the contributor won't be rewarded for that epoch. The contributor rewards calculation has fallback behavior — if too many data points are missing in the current epoch, it falls back on a previous epoch's data.
• Future epochs: New ThirdPartyLatencySamples accounts will be initialized with the new 600-second (10-minute) interval, and samples will arrive at the expected rate.

This transient impact on the current epoch is acceptable.

Files to Change

File	Change
controlplane/internet-latency-collector/cmd/collector/main.go	Change defaultRipeAtlasSamplingInterval from 6 * time.Minute to 10 * time.Minute. Change defaultRipeAtlasExportInterval from 6 * time.Minute to 10 * time.Minute.
controlplane/internet-latency-collector/internal/ripeatlas/collector_test.go	Update the test at ~line 855-869 to use 10 * time.Minute instead of 6 * time.Minute, and update the comments: "240 samples per day" to "144 samples per day", expected daily credits from 720 to 432 (3 sources x 144 samples/day = 432).

No new files need to be created.

Post-Deployment Steps

After deploying the updated binary:

1. Run atlas clear-measurements to stop all existing 6-minute measurements.
2. The service's hourly loop will recreate measurements at the new 10-minute interval (or trigger manually with atlas create-measurements).
3. The current epoch's ThirdPartyLatencySamples account may show fewer samples than expected — this is acceptable per operator confirmation and RFC4's fallback behavior.

Risks & Considerations

1. Reduced data resolution: Going from 240 to 144 samples per day means coarser latency data. This is an acceptable tradeoff to stay within RIPE Atlas daily limits.

2. Current epoch sample gap: Stopping and recreating measurements mid-epoch will cause a gap in the current epoch's data. Per RFC4, missing data is filled with zeros and included in p95 calculations. If a contributor's link loses >5% of data, the rewards calculation falls back on a previous epoch. The operator has confirmed this is acceptable.

3. Onchain sampling interval mismatch: The current epoch's ThirdPartyLatencySamples account stores sampling_interval_microseconds = 360000000 (6 minutes). After the change, samples arrive every 10 minutes, so fewer samples than expected will be recorded for the remainder of the epoch. New epochs will be initialized with sampling_interval_microseconds = 600000000 (10 minutes) and will be consistent.

4. Export interval alignment: Changing defaultRipeAtlasExportInterval to match the sampling interval keeps them synchronized. Exporting at 6 minutes when samples arrive every 10 minutes would cause 40% of export cycles to find no new data, which is wasteful but not harmful. Aligning them is cleaner.

Testing Strategy

1. Unit tests: Run go test -v ./controlplane/internet-latency-collector/... to verify the updated test passes with the new 10-minute interval value and updated comments.

2. Build verification: Run make go-build to confirm compilation.

3. Lint: Run make go-lint to confirm no lint issues.

Estimated Scope

Small (< 100 lines changed) — Two constants changed in main.go, one test value and a few comments updated in collector_test.go.

Medium

• [Testability]: The TestInternetLatency_RIPEAtlas_ExpectedDailyCreditsMetric test does not actually assert the metric value; it relies on a t.Log statement to describe expected behavior.

  • Location: controlplane/internet-latency-collector/internal/ripeatlas/collector_test.go:867-869
  • Recommendation: This is a pre-existing issue, not introduced by this diff, but the test was updated to reflect new math (432 instead of 720) without addressing the fundamental gap. The comment on line 867 says "we can't directly check the metric value in tests" -- but Prometheus metrics can be read in tests via testutil.ToFloat64() from the prometheus/testutil package. Consider adding an actual assertion on metrics.RipeatlasExpectedDailyCredits to make this test meaningful rather than purely documentary. As-is, the test exercises the code path but does not validate the output it claims to verify.

• [Configuration / Implicit Coupling]: The defaultRipeAtlasSamplingInterval and defaultRipeAtlasExportInterval are kept in sync (both changed from 6 to 10 minutes) but there is no validation or documentation enforcing their relationship.

  • Location: controlplane/internet-latency-collector/cmd/collector/main.go:32-34
  • Recommendation: The export interval must be at least equal to the sampling interval to avoid polling for results that cannot yet exist. Today these are both hardcoded constants that happen to be equal, but samplingInterval is not configurable via CLI while exportInterval is not either -- they are both hardcoded defaults. If either becomes configurable in the future, there is no validation that exportInterval >= samplingInterval. Consider adding a validation check in Config.Validate() (in collector.go) or at minimum a comment explaining why these two values are aligned.

Low

• [Documentation / Readability]: The runCmd long description on line 97 still says "exports RIPE Atlas results every 2 minutes" which is now stale -- the default export interval is 10 minutes.

  • Location: controlplane/internet-latency-collector/cmd/collector/main.go:97
  • Recommendation: Update the long description string to match the new 10-minute default, or remove the specific interval reference to avoid future staleness (e.g., "exports RIPE Atlas results periodically").

• [Backward Compatibility]: Changing the default sampling interval from 6 to 10 minutes will alter the behavior of existing RIPE Atlas measurements on redeployment. Existing measurements configured at 6-minute intervals will be recreated at 10-minute intervals during the next measurement management cycle, which is the intended effect. However, there is no migration path or warning for operators who may have been relying on the 6-minute cadence.

  • Location: controlplane/internet-latency-collector/cmd/collector/main.go:32
  • Recommendation: This is acceptable for a configuration default change, but consider noting in the PR description or release notes that existing measurements will be recreated with the new interval on the next management cycle.

• [Naming / Readability]: The constant defaultWheresitupSamplingInterval remains at 6 minutes while RIPE Atlas intervals moved to 10 minutes. The asymmetry is fine functionally (different providers, different rate limits), but it may be worth a brief comment explaining why these differ, since they were previously aligned.

  • Location: controlplane/internet-latency-collector/cmd/collector/main.go:35
  • Recommendation: Optional -- add a brief comment on the RIPE Atlas constants explaining the 100k daily results limit motivation if it is not documented elsewhere.

Summary

This is a clean, low-risk configuration change that correctly updates both the sampling interval and export interval defaults, along with corresponding test expectations. The main area for improvement is the stale command description on line 97 and the fact that the test for expected daily credits still lacks an actual metric assertion. No architectural concerns with the change itself.

Summary

This diff is a purely configuration-level change that adjusts two timing constants (defaultRipeAtlasSamplingInterval and defaultRipeAtlasExportInterval) from 6 minutes to 10 minutes, along with corresponding updates to test comments and expected values. There are no changes to input handling, authentication, authorization, data flow, external interfaces, dependencies, or secret management. The change introduces no new security risk.

Work Log — waiting_review

I'll start by reading the key files mentioned in the plan, then implement the changes.

Now I have the full picture. Let me implement the changes.

Now update the test file:

Now let me run tests and build in parallel.

The output is very long. Let me check if there are any actual failures relevant to our changes.

All internet-latency-collector tests pass. The two FAILs are in client/doublezerod/internal/liveness and e2e/internal/rpc — unrelated to our changes. Let me verify these are pre-existing failures.

The liveness failure didn't show up in this run. Only e2e/internal/rpc failed, which is unrelated to our changes. Our internet-latency-collector tests all pass. Let me also run lint.

All clear. Let me now get the diff and run the reviews.

The changes aren't committed yet, so the diff is empty against HEAD. Let me get the unstaged diff instead.

Now launch both review sub-agents in parallel.

Both reviews found no critical or high issues. Let me fix the stale description mentioned in the architecture review (line 97 of main.go), then post both reviews to GitHub and proceed.

The description says "every 2 minutes" which was already stale before our change (it was 6 minutes). Let me update it to avoid specific numbers.

Now post both reviews to GitHub as separate comments.

Now post the reviews as GitHub comments.

Both reviews posted. No critical or high findings — all medium/low. Now clean up the temp review files and proceed to commit/push/PR.

Now let me rebase on main, commit, push, and create the PR.

No commits yet on this branch. Let me check current status and recent commit style.

Branch is already on top of main (no divergence). Let me rebase to make sure, then commit the changes.

Up to date. Now commit and push.

Now create the PR.

Clean up the temp file.

STATUS: COMPLETE
