Summary

Do a final pass over extensions/mongodb/docs/DESIGN.md and the implementation plan, updating them to reflect any deviations found during implementation (adjusted defaults/caps, driver quirks, error-message wording), so the docs match the code.

Background

Depends on: #143, #144

Implementation reality often diverges from a design written up front: the driver's actual behavior for the installed version, constants that were tuned, error-message phrasing that changed, TypeBox schema details, the confirmation-log format. This step (mirroring the sibling victorialogs extension's Phase 6 practice) closes that gap. All implementation work should be complete before this step — this is documentation reconciliation, not implementation.

Implementation Details

Read extensions/mongodb/docs/DESIGN.md and extensions/mongodb/docs/IMPLEMENTATION_PLAN.md.
Walk the actual implementation: extensions/mongodb/index.ts, src/** (env, defaults, serialize, errors, tools), the tests, and the README.
Identify every deviation: changed constants (e.g. if FIND_LIMIT/OUTPUT_BYTE_CAP were tuned), different error-message wording, driver API differences in the installed mongodb major (e.g. v7 vs v6 specifics), schema details, the exact confirmation-log format.
Update DESIGN.md so it matches the implemented behavior. For each deviation, either fix the doc or add an explicit note justifying why the doc keeps the original intent.
If the implementation plan is superseded by the issues created from it, say so in a note in the plan file rather than deleting it.
Keep the Rollout Notes section of DESIGN.md accurate.

Acceptance Criteria

DESIGN.md reflects the implemented behavior (constants, error messages, tool schemas, lifecycle, confirmation log).
Every deviation found in the walkthrough is documented (doc fixed, or justified in a note).
No stale claims remain (e.g. wrong default/cap values, wrong message prefixes, claims about tools that don't exist).
The plan file carries a note about its status if superseded.

Test Plan

Side-by-side read of the docs and the code:

ls extensions/mongodb/src extensions/mongodb/src/tools
grep -rn "FIND_LIMIT\|OUTPUT_BYTE_CAP" extensions/mongodb/src
grep -n "MongoDB extension loaded" extensions/mongodb/index.ts

Diff every claim in DESIGN.md against what the code actually does; fix or annotate each mismatch.

## Summary Do a final pass over `extensions/mongodb/docs/DESIGN.md` and the implementation plan, updating them to reflect any deviations found during implementation (adjusted defaults/caps, driver quirks, error-message wording), so the docs match the code. ## Background **Depends on:** #143, #144 Implementation reality often diverges from a design written up front: the driver's actual behavior for the installed version, constants that were tuned, error-message phrasing that changed, TypeBox schema details, the confirmation-log format. This step (mirroring the sibling victorialogs extension's Phase 6 practice) closes that gap. All implementation work should be complete before this step — this is documentation reconciliation, not implementation. ## Implementation Details 1. Read `extensions/mongodb/docs/DESIGN.md` and `extensions/mongodb/docs/IMPLEMENTATION_PLAN.md`. 2. Walk the actual implementation: `extensions/mongodb/index.ts`, `src/**` (env, defaults, serialize, errors, tools), the tests, and the README. 3. Identify every deviation: changed constants (e.g. if `FIND_LIMIT`/`OUTPUT_BYTE_CAP` were tuned), different error-message wording, driver API differences in the installed `mongodb` major (e.g. v7 vs v6 specifics), schema details, the exact confirmation-log format. 4. Update DESIGN.md so it matches the implemented behavior. For each deviation, either fix the doc or add an explicit note justifying why the doc keeps the original intent. 5. If the implementation plan is superseded by the issues created from it, say so in a note in the plan file rather than deleting it. 6. Keep the Rollout Notes section of DESIGN.md accurate. ## Acceptance Criteria - [ ] DESIGN.md reflects the implemented behavior (constants, error messages, tool schemas, lifecycle, confirmation log). - [ ] Every deviation found in the walkthrough is documented (doc fixed, or justified in a note). - [ ] No stale claims remain (e.g. wrong default/cap values, wrong message prefixes, claims about tools that don't exist). - [ ] The plan file carries a note about its status if superseded. ## Test Plan Side-by-side read of the docs and the code: ```bash ls extensions/mongodb/src extensions/mongodb/src/tools grep -rn "FIND_LIMIT\|OUTPUT_BYTE_CAP" extensions/mongodb/src grep -n "MongoDB extension loaded" extensions/mongodb/index.ts ``` Diff every claim in DESIGN.md against what the code actually does; fix or annotate each mismatch.
