ADR-0028 complete (per handoff-21); ADR-0029 (column
constraints) written, accepted, and implemented through
commit 4 of 6 — NOT NULL / UNIQUE / DEFAULT / CHECK at
`create table` and `add column`. Commits 5 (`add constraint`
/ `drop constraint` + the §5 dry-run) and 6 (friendly errors
+ typing-surface matrix) are planned in full in §4.
ADR-0028 (query plans / `explain`) is fully implemented; the
handoff-16 design trio (ADR-0026 / 0027 / 0028) is now closed.
- handoff-21: session summary, the two deliberate deviations
from handoff-20's plan, test coverage, open clusters.
- requirements.md: QA1 / QA2 ticked.
- CLAUDE.md: the `EXPLAIN QUERY PLAN` deferred-items line
updated to "implemented per ADR-0028".
Interim handoff. ADR-0028 (query plans / explain) is started:
step 1 (the styled-output-line mechanism, 03d8a09) is done and
committed. handoff-20 carries the full validated build plan
for steps 2-5 with file:line anchors and three implementation
gotchas (the const/static Subgrammar wrinkle, build_show's
positional dispatch, and why steps 2+3 must land as one
commit) so a fresh session implements them without
re-exploring.
handoff-19 §2 now records the two bugs as fixed (was "queued
next"): the optional trailing-flag completion fix (f239ca5)
and the --resume temp-project pointer fix (3a40ae2). §5 drops
them from "what's next" — ADR-0028 is now the natural next
pick. State/§6 updated to 10 commits and 1131 tests;
requirements.md test baseline → 1131.
ADR-0027 gains a "Follow-up" section recording the completed
§2 highlight + hint wiring and precise per-literal WARNING
spans; the three stale As-built bullets point at it.
requirements.md test baseline → 1125 and the S6 entry notes
the completion + Amendment 1. handoff-19 records the run and
queues the two deferred manual-testing bugs (add 1:n
relationship completion/usage hint; --resume / last_project)
as the next session's first work.
The multi-form usage-template fix (151ed08) and the reviewed
`add index` syntax decision (kept as-is), so the next agent
does not re-flag a settled question.
ADR-0024 audited as fully implemented. Amend the ADR with a "Phase F
minimal" implementation note (parser.rs retained as the router +
ParseError home) and update the README index line to match.
Reconcile docs/requirements.md against handoffs 10-14: refresh the
test baseline (449 -> 1006), mark U4 (replay) satisfied, correct the
A1 / H1a / H3 progress notes.
Amend handoff-14: §3 flagged items both resolved (ranker kept,
CommandNode.hint_mode removed); §4 rewritten as a concrete next-work
pointer at the reconciled requirements.md.
Documents this session's work and the recommended next move:
## Session totals
- 11 commits since handoff-5
- 534 → 610 tests passing (+76)
- Release binary 7.2 → 7.8 MB
## What landed
- All four non-CI items from handoff-5's Independent Work
list: B2 (int→bool tests), B1 (help update), A2 (engine-
vocabulary audit), A3 (replay command)
- ADR-0019 fully implemented end-to-end:
- Friendly-error layer + i18n catalog (~170 entries
across 16 categories)
- §6 runtime row-pinpoint enrichment with
schema-resolved facts
- §9 migration sweep — every user-visible literal in
src/ now flows through the catalog (caught a ui.rs
gap during the post-sweep manual sanity check, folded
it in as sweep 3/3)
## Recommended next move
Parser-as-source-of-truth ADR + H1a implementation. The
friendly-error layer made engine errors much better;
parse-error wording is now the visibly-weakest user
surface. User explicitly surfaced the gap during manual
testing this session ("typing `create` should illustrate
the expectation"). Bounded scope, high pedagogical value,
unblocks I3/I4 in passing.
A1 (CI workflow) noted as the easy alternative for a
quick win first.
## Sharp edges captured
- New i18n workflow: catalog + keys.rs + t!() at every
use site, validator catches drift
- TranslateContext is owned (no lifetime); App combines
runtime FailureContext with verbosity
- Anchor phrases load-bearing per ADR-0019 §10
- `running: ` prefix coupled to caret-padding math
- main.rs initialises catalog before args parsing
- Several alignment-coupled strings deliberately left out
of the catalog (echo prefix tags, mode labels)
Closes out track 2's ADR-0015 backlog.
* `--resume` CLI flag (L1a, ADR-0015 §7) opens the most-
recently-used project, tracked in <data-root>/last_project.
Mutually exclusive with a positional <project-path>; errors
cleanly to stderr (above the shell prompt) on missing file
or stale recorded path. last_project is rewritten on every
successful project open (startup, load, new, save as,
import).
* Persistent input history (I2-persist, ADR-0015 §12). On
project open, the in-memory navigable history is hydrated
from the tail of history.log (capped at the in-memory cap).
ProjectSwitched gains a `history_entries` payload field;
App::seed_history is the entry point. Pipes inside source
text round-trip via splitn(3); unknown escape sequences are
passed through literally.
* Migration framework scaffold (F3, ADR-0015 §9). New
persistence::migrations module with MigratorRegistry +
migrate_to_latest + ensure_project_yaml_migrated. Empty
in v1 (production registry has no migrators); the loader
runs through it on every project open and is exercised by
tests with a fake v1→v2 migrator. Writes
project.yaml.v<N>.bak before any migrator runs; verifies
each step bumps the version field.
Refreshes docs/requirements.md (A1 / I2 / F3 / E1 / L1a /
test baseline) and adds docs/handoff/20260508-handoff-3.md
covering both Iter 5 and Iter 6.
Total tests: 408 passing, 0 failing, 0 skipped (up from 345
at handoff-2). Clippy clean.
Adds docs/handoff/20260508-handoff-2.md describing the state at
the end of this session: ADR-0015 designed, Iterations 1-4 of
track 2 shipped (file-backed projects with auto-named [temp]
dirs, per-command write-through, rebuild from text on missing
.db, save/save as/new/load/rebuild commands with modal dialogs
and project switching), plus the cleanup pass (--help, in-app
help, post-rebuild message, unmodified-temp cleanup) and the
safety hardening of safely_delete_temp_project. Lists the
next-up moves (Iteration 5: export/import, Iteration 6:
--resume + persistent input history + migration scaffold) and
an end-to-end smoke test.
requirements.md: marks P1-P5, P-NAME-1/2/3, F1, F2, U3, L1 as
[x] with iteration references; adds P-CLEAN-1 for the safe
cleanup; updates A1, I2, H3, L1a progress notes.
CLAUDE.md: updates the project-storage decisions and
deferred-items entry to reflect what's now live vs. still
pending.
- New docs/handoff/20260507-handoff-1.md captures session
state, what's implemented, what's pending (ranked
recommendations for next moves), sharp edges, and a
smoke-test sequence.
- CLAUDE.md updated to reflect current reality: ADRs 0008-
0014 added to the decisions-at-a-glance list, the
"repository layout (planned)" placeholder replaced with
the actual layout, key invariants spelled out, deferred
list rebuilt from current requirements.md.
