}1 # Decision: Test-double strategy (S5) 2 3 Pattern: rotating devil's advocate, decision 3 of 3 (seat: Marisol Ferran). Proposer: Renata Cole. 4 5 ## Proposal 6 7 Hand-written interface fakes (not generated mocks) for DAO/handler tests — the `Repository` composite and its three sub-interfaces are small and stable enough that a fake struct with configurable fields/funcs per test is less overhead than adopting a codegen tool (`gomock`/`mockery`) for this scope. 8 9 ## Objections — Marisol Ferran (Enthusiast) 10 11 1. **Interface drift is silent with hand-written fakes.** A new interface method still compiles against a stale fake, which silently zero-values it instead of failing a test that should catch the gap. Generated mocks fail loudly or leave a visibly regenerated stub. Marisol's own mitigation: enforce fake regeneration in the same PR as any interface change, as a review checklist item — makes drift a procedural risk, not a tooling one. 12 2. **Call-count/ordering assertions are free with mocks, hand-rolled with fakes.** Conceded this is likely moot here — S2–S4's test cases are table-driven input/output, not call-sequencing assertions. 13 3. **Legibility to a reviewer** — conceded weak by Marisol herself: a 3-method, ~20-line fake is faster to read and trust than looking up `mockgen` syntax, for a project this size. 14 15 Marisol's own assessment: objection 3 doesn't hold at this scale; objections 1 and 2 are real at scale but this project may not have that scale. 16 17 ## Ruling (Renata Cole) 18 19 **Hand-written fakes stand** — objection 3 was conceded by its own author, and objection 2 doesn't apply given the table-driven test shape already committed to in S5. Objection 1 is real but has a cheap procedural fix, which is adopted rather than reaching for a codegen dependency to solve it. 20 21 Adopted: any change to `Repository` or its three sub-interfaces must update the corresponding hand-written fake in the same PR — added as a stated review-checklist item for S2/S5, not left as an assumed discipline. This is the review-time equivalent of what a generated mock would catch automatically, at zero added dependency cost. 22 23 ## Status 24 25 Ruled. No codegen/mocking library added to the module. Carries into S5 as a review-checklist line item. 26 27 --- 28 Model: sonnet (Marisol Ferran, objection seat; Renata Cole, lead, proposer + ruling). Turns consumed: 1 hire turn + lead synthesis. 29

SQLite's migration is unchanged.\n- `internal/dao/postgres/credentials.go`, `internal/dao/sqlite/credentials.go`: removed the Go-side `strings.ToLower` call in `GetByUsername` — the fold now happens entirely in SQL (`LOWER(username) = LOWER(?)`), the same expression that builds `uq_user_credential_username`'s index, so index and lookup agree by construction within a backend.\n- `internal/dao/conformance`: two new assertions — `TestConformance_PhoneE164BoundaryParity` (the same phone string accepted/rejected identically at the 6/7/15/16-digit boundaries across all three backends) and `TestConformance_UsernameCaseInsensitiveLookup` (two usernames differing only by ASCII case both resolve to the same row via `GetByUsername`, on every backend — distinct from the existing duplicate-username-on-create test, which only proves the uniqueness constraint fires, not that a differently-cased lookup finds the row afterward).\n\n## Verification\n\n`go build`/`go vet` clean. `go test ./...` green against real Postgres 16, real CockroachDB v23.2.0, and `modernc.org/sqlite`, including both new assertions and the full existing suite (no regressions).\n\n## Who did the work\n\n- **Yusuf Karadag** (05 Data Ops, Detail Hawk) — found both defects, reading the contract rather than running anything.\n- **Priya Nandakumar** (05 Data Ops, lead) — ruled amendment A6.\n- **Renata Cole** (03 Engineering & Delivery, lead) — this fix and verification.\n- Model: Claude Sonnet 5, via Claude Code.\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\nhttps://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\""

"description": "Check migration-approach.md's numbering/versioning convention"
}7:Status: **final.** The devil's-advocate objection turn (story S4 in `./PLAN.md`) ran and raised six objections; all six were accepted. The two I named as most worth attacking — the tool choice and the single-runner requirement — were indeed where it landed: R2's *conclusion* survived but its *reasoning* was wrong and has been replaced, and R3 was found to be checking one version number where §2 creates two. Dispositions: `./decisions/migration-approach-objections.md`. 9:## 1. Tool: goose 11:**goose** — a Go command-line migration runner that applies numbered `.sql` files in order and records which have been applied in a version table inside the target database. Plain-SQL-first, minimal dependencies. Reasoning is in `./multi-db-strategy.md` and `./research-data-ops-best-practices.md` §3: this schema is "mostly shared DDL, occasionally per-backend", and goose's loose directory model fits that better than golang-migrate's stricter paired up/down files. golang-migrate is an equally defensible tool and I will not contest a swap if 03 already has tooling preferences — **nothing in §3–§6 below changes if the tool changes — with one named exception**: §2's two-invocation mechanism uses goose's `-table` flag, so a swap to golang-migrate means re-deriving how two independent version sequences are kept apart. That is the tool-independence claim's only load-bearing use, and pretending otherwise would be the kind of small overclaim this document is otherwise trying to avoid. Atlas is the schema-as-state alternative worth knowing about; it is more than this take-home needs. 13:Version numbering: timestamped filenames during development (avoids collisions when two branches add a migration), converted to a clean sequential 001/002/003 series with `goose fix` — the subcommand that renumbers timestamped files — **before the migrations have been applied anywhere that persists.** That cutoff is the important half: renumbering after application rewrites history the version table already records, so `goose fix` is a pre-first-application step, not a tidy-up before tagging. Not a decision 04 needs to act on — noted so nobody "fixes" the inconsistency later. 47:**Mechanism 04 needs:** goose applies one directory per invocation, so a migration run is **two invocations — the backend directory FIRST, then `shared/`** — and each needs its own version table (`goose -table goose_db_version_<driver>`, then `-table goose_db_version_shared`). One shared table across two directories would interleave version numbers from independent sequences and corrupt the history. Both invocations must succeed for the run to count as successful. 65:**The conclusion survives on a different and better reason: a transaction-scoped lock cannot cover a migration run.** `pg_advisory_xact_lock` is released when its transaction ends, and goose applies each migration file in its own transaction. The lock would therefore be released *between files*, letting a second runner interleave mid-run — which is precisely the failure it was supposed to prevent. Session-scoped locks, which would span the whole run, are the ones CockroachDB does not support. So the database can offer either the right scope or the right engine coverage, never both. 69:**A cheap portable backstop worth adding regardless — and an honest gap.** goose's version table is the one artifact all three backends share, so a unique constraint on its `version_id` would make a second concurrent runner fail on insert: portable, free, no platform feature required. **Whether goose's default version table already carries that constraint is unverified here** — I am not asserting it either way, because the objection that raised this correctly pointed out that the document claimed the database could not help without examining the one database-level mechanism goose already creates. The actionable form does not depend on the answer: **add a unique index on `version_id` ourselves in the first migration**, which is portable across all three backends and costs nothing if goose already does it. This is a backstop, not a replacement for R2 — it turns a silent interleave into a loud failure, which is the property actually worth buying. 85:Idempotent via `INSERT ... ON CONFLICT (name) DO NOTHING`, which the unique constraint on `auth_method.name` already supports and which all three backends accept (the same portable upsert form the DAO uses — see `./multi-db-strategy.md`). goose will not re-run an applied migration anyway; the `ON CONFLICT` makes the file safe against a database someone seeded by hand, which in practice is how this breaks. 91:Named so 04 does not read a boundary into this doc that isn't there: where the databases actually run; how the pipeline invokes goose; environment topology and how many of them there are; backup schedule and retention of backups; connection pooling; monitoring of migration runs. All 04's. This document says *what must be true* about migration execution and *why*, and stops there.

Verified the regex boundary math digit-by-digit: `^\\+[1-9][0-9]{6,14}$` requires 1 mandatory digit plus 6-14 more, so 7-15 total digits — matching SQLite's `length BETWEEN 8 AND 16` (which counts the `+`) exactly. Hand-traced all four new test cases (6/7/15/16 digits) against both patterns; no off-by-one either side.\n\nTwo non-blocking notes for the record:\n1. `GetByUsername`'s case-insensitivity guarantee now depends entirely on each backend's SQL `LOWER()` matching its own index expression, rather than being partly checked in Go. Correct per 05's ruling, just noting the guarantee's locus moved from \"Go, checked by tests\" to \"index-expression parity per backend, checked by conformance.\"\n2. The two migration files' digit-range comments assert they're \"kept in sync\" with no automated coupling (no shared constant, no lint) — a future one-sided edit wouldn't be caught until the conformance suite ran.

Fixed in e61d165: `00001` reverted to its original, already-applied text; the actual narrowing now lands as a real `00002_phone_e164_narrow_range.sql` migration in both `migrations/postgres/` and `migrations/cockroachdb/`, applied through the normal pipeline.\n\nTwo related things worth naming, both addressed in the fix commit:\n- Postgres's `00002` uses `ADD CONSTRAINT ... NOT VALID` + a separate `VALIDATE CONSTRAINT`, not a plain `ADD CONSTRAINT`, to avoid holding a full-table-scan lock for the ALTER's whole duration — the general pattern to use regardless of whether this specific table holds production data yet.\n- Verifying this end-to-end (not just against a fresh from-scratch schema) surfaced a second, independent issue: CockroachDB rejects `DROP CONSTRAINT` followed by `ADD CONSTRAINT` with the *same name* in one transaction (\"duplicate constraint name\") — something a conformance run that only ever stands up 00001+00002 together on a fresh schema wouldn't catch, but a real incremental deploy applying 00002 on top of an already-migrated database would hit immediately. Both migration files now carry `-- +goose NO TRANSACTION` so each statement commits independently.\n\n`GetByUsername`'s case-fold change: confirmed no wildcard/injection surface (`LOWER(username) = LOWER($1)` is an equality predicate, not `LIKE` — `%`/`_` are literal characters either way) and no behavior change for any input, since the SQL-side `LOWER()` was always applied on top of the removed Go-side call.\n\nOne thing flagged for the record, not fixed here (agreed out of this PR's scope): the fix closes the *within-backend* fold disagreement but leaves a *cross-backend* one standing — Postgres's `lower()` is locale-aware, SQLite's is ASCII-only, so a non-ASCII-cased username could still fold to different strings per backend. Same class of defect A6 just closed, one edge over.\n\nVerdict: approve, contingent on (and now satisfied by) the migration-restructure fix in e61d165 — verified end-to-end against real Postgres 16 and CockroachDB v23.2.0, incremental 00001-then-00002 application, all green.\n\nWork-By: Nolan Reyes (QA)\nEOF\n)\""

Fixed by reverting 00001 and adding a real 00002_phone_e164_narrow_range.sql migration to both postgres/ and cockroachdb/ directories, applied through the normal pipeline (Postgres uses ADD CONSTRAINT NOT VALID + VALIDATE CONSTRAINT to avoid a full-table lock; both need `-- +goose NO TRANSACTION` since CockroachDB rejects a same-transaction DROP+ADD of a same-named constraint — caught while verifying the incremental apply path, not just a fresh-schema stand-up).\n\nVerified end-to-end against real Postgres 16 and CockroachDB v23.2.0 with the actual incremental 00001-then-00002 sequence a real deploy would run, both new conformance assertions and the full suite green. Both reviews posted, pushed at e61d165. Ready for the merge gate whenever convenient.",
