Delete the byte-oriented KVStore/VersionedStore abstraction and the
DynamoDB/memory KV backends. Add a generic typed store (DocStore[T] with
Provider/Collection/Typed) persisting each value as a flattened native
Mongo document (storedDoc[T] via bson inline) — no value envelope.
- MongoDB is the only runtime backend; memory kept for tests/local.
- All modules + deploynotify use typed stores; persisted structs carry
bson tags == json names (incl. nested lolschedule/wordle types).
- lolschedule wraps its array/scalar values in named structs.
- migrate-dynamo-to-mongo writes the flattened shape via Typed[bson.M]
with wrap rules; Scan/--dry-run/--verify retained.
Verified: go vet/build clean; full go test green hermetically and
in-container vs real Mongo 7 + DynamoDB Local (storage integration +
migrator e2e).
Delete Firestore provider implementation and tests (5 files). Extract shared
key helpers to new internal/storage/keys.go module. Remove Firestore case
from server bootstrap and storage factory. Drop cloud.google.com/go/firestore
and related dependencies from go.mod. Remove firestore-emulator test targets
from Makefile. Update README storage section to reflect MongoDB-only backend.
Replace content-addressed storage versioning (CAS) with explicit version fields
on documents. Versions are managed via optimistic locking pattern: Get returns
version, Put increments atomically and fails if version mismatch detected.
Callers (portfolio, lolschedule) updated to use GetVersioned/PutVersioned,
simplifying concurrency handling and eliminating CAS overhead.
Persist the KV value field as a BSON string so it is directly readable in
the Atlas/Compass UI, matching DynamoDB's String storage. Reads still accept
BSON binary as a backward-compat fallback. Non-UTF-8 callers must encode
upstream, same constraint as DynamoDB; all current callers write JSON.
- prefix.go: return errors.ErrUnsupported when inner store lacks CompareAndSwap, enabling fail-fast instead of infinite retries
- Adds comprehensive CAS semantics test coverage for all KV backends:
* memory_kv_test.go: new tests for basic operations and CAS failures
* prefix_test.go: tests for wrapped CAS errors and unsupported operations
* dynamodb_kv_test.go, firestore_kv_test.go: CAS failure scenarios
- portfolio_test.go: test retry exhaustion, business-error short-circuit, concurrent updates, and fail-fast on unsupported CAS
Operator-run tooling that moves durable Cloudflare KV data into the live
AWS DynamoDB table, plus a runtime swap of the `value` attribute from
Binary to String so payloads are human-readable in the AWS console.
- cmd/migrate_cf_data: subcommands inventory, kv-import (idempotent via
attribute_not_exists), trading-audit-dump, convert-value-to-string
- internal/migration: policy allowlist, CF KV+D1 REST clients, DynamoDB
writer, report formatter with per-prefix counts + tests
- internal/storage/dynamodb_kv.go: Put writes MemberS, Get reads MemberS;
dropped empty-bytes sentinel (DynamoDB allows empty strings)
Rename:
- Go module github.com/tiennm99/miti99bot-go → github.com/tiennm99/miti99bot
- CloudFormation stack miti99bot-aws-port → miti99bot
- Drop "port", "Cloud Run", "GCP", "cutover", "Phase NN" framing from
active code and docs — project reads as canonical AWS-Lambda from now on.
AWS deploy guide + flow fix:
- New docs/deploy-aws-free-tier-guide.md — Ubuntu 24.04 ARM64 onboarding
with project-local venv (pip awscli + sam-cli), SSM secrets via read -s,
idempotent OIDC provider + role creation, $1 budget alarm.
- Drop sam build from the pipeline — provided.al2023 + makefile builder
expects a Makefile in CodeUri (build/lambda/, the output dir), so the
step always fails. sam deploy --template-file template.yaml now reads
the raw template and zips build/lambda/ directly.
- Rollback section rewritten — use continue-update-rollback /
cancel-update-stack / git-SHA redeploy. Drop the broken
--use-previous-template recipe.
- DynamoDB free-tier row corrected (on-demand is 2.5M read / 1M write
request units, not 25 RCU/WCU).
Updated:
- README.md fully rewritten (drops port/legacy framing, lists modules,
points new users at the free-tier guide).
- aws/README.md retitled "AWS account setup", phase numbers stripped.
- Makefile / .github/workflows/deploy.yml — sam deploy flow.
- samconfig.toml — stack_name = "miti99bot".
- Go comments — Cloud Run → Lambda, Cloud Scheduler → EventBridge
Scheduler, Cloud Logging → CloudWatch Logs.
- Struct field GCPProject → FirestoreProject (env GOOGLE_CLOUD_PROJECT
unchanged).
Plus advisory reports under plans/reports/ from the code-reviewer +
researcher passes that informed the fixes.
Verified: go vet ./..., go build ./..., go test ./... all green.
Removes six modules (loldle-ability/emoji/quote/splash, semantle, doantu)
and prunes the framework deps that were only there to serve them:
- ai.Embedder + Client.Embed + embeddingModel const (semantle only)
- Deps.Embedder + BuildOptions.Embedder
- Deps.Env + Build(env) param + ModuleEnv config field + PHOW2SIM allowlist (doantu only)
- internal/champname package (loldle now owns its lookup helpers directly)
- template.yaml: Phow2simAPIURL parameter + PHOW2SIM_API_URL Lambda env
Active catalog: util, misc, wordle, loldle, lolschedule, twentyq, trading.
go build / vet / test all pass.
- Implement DynamoDB client wrapper and KV provider
- Full CRUD test coverage for both local and AWS modes
- AWS SDK v2 dependency added to go.mod/go.sum
Phase 6 of the 2026-05-09 review remediation plan. Bundle of small
hygiene fixes — none individually urgent but better folded together
than scattered across follow-ups.
- .golangci.yml: enable errcheck/govet/gosec/staticcheck/unused/
ineffassign/gocyclo/misspell/revive. Tuned to the codebase style
(no universal exported-doc requirement, gocyclo cap at 20 to
accommodate handler dispatch). 0 issues across the tree.
- ci.yml: add golangci-lint job + govulncheck (informational).
- Defensive guards:
- registry.go: Module.Name mismatch now errors at Build instead of
silently overwriting (TestBuild_RejectsFactoryNameMismatch).
- cmd/server/main.go: PORT env validated numerically + 0..65535.
- firestore_provider.go: For() re-validates module name; invalid
names return an invalidStore whose every op errors with
ErrInvalidModuleName.
- Dead code removal:
- wordle: gameTTLSeconds const + pickDaily/hashDJB2/todayUTC
helpers + their tests deleted (pickDaily was unused;
daily.go renamed pick_random.go).
- Dependency: golang.org/x/net v0.52.0 -> v0.54.0 (resolves
GO-2026-4918 HTTP/2 infinite-loop CVE).
- Deferred from the original phase plan: Docker digest pinning
(Dependabot handles), per-handler file splits (largest file 279 LOC;
splits would churn for marginal gain).
go test -race -count=1 ./... clean (15 packages); golangci-lint run
clean (0 issues).
Implements Phases 02 (partial) and 03 of the go-port-cloud-run plan.
Introduces module framework with per-module KV prefix isolation,
health check endpoint, request timeout protection, and comprehensive
test coverage. Cloud Run deployment deferred to Phase 01.
Security hardening: constant-time secret comparison, cron auth bridge,
and secrets stripped from dependency environment exports. Includes
Dockerfile, GitHub CI workflow (vet + race + build), and integration
tests for module lifecycle.
