glm-5.3-flash 4165c94ab0 docs: specify POC #1 — SQLite engine posture comparison (poc-sqlite-posture-spec.md)
Arm A: honker-core linked on our rusqlite (bridge per REQ-TTY-01, honker's watcher). Arm B: honker extension .so over sqlx-sqlite (natively async call path, own watcher, per-pool-connection extension + bootstrap — stress-testing what the CI proof script doesn't cover: pool wiring, lost connections, full surface). Option 2 (honker-rs-as-substrate) dropped from scope with reasoning: its mutex-pinned sync transaction model is subsumed by both other postures' trade space. Five probes (async seam, watcher, transactional contract, packaging, cross-process interop), a decision gate including a legitimate hybrid verdict, and out-of-scope boundaries (postgres side, full surface, extension-as-consumer-feature regardless of outcome). Phase-0: POC register added, plan/frontmatter updated; AGENTS.md: POC-register convention codified.

# AGENTS.md
Operating instructions for opencode agents working in this repo. opencode
auto-loads this file as instructions, overriding the built-in defaults for
this project. Custom agents in `.opencode/agents/` inherit these rules
unless their own prompts say otherwise.
## Repo posture
This repo is in **Phase 0 (Exploration)** per `docs/sdd_process.md`.
There is no crate yet — no `Cargo.toml`, no `src/`, no README (the README
gets written just before first publish, so it can be honest about what
shipped). What exists is `docs/research/phase-0.md` (the Phase 0
document: vision, prior art, open questions, POC register), the SDD
process (`docs/sdd_process.md`), and the agent defs
(`.opencode/agents/`). Do not scaffold implementation code
from this posture unless a task or the user asks for a POC.
Do not treat `docs/research/phase-0.md` as settled architecture — it is
a working research document whose open questions are genuinely open.
The hedging rules of `docs/sdd_process.md` (no circular deferrals, no
"resolved with escape hatches") still apply to it.
## Git Workflow
**Commit and push when reasonable.** When a change is complete and
verified, commit and push to `origin/main` without asking. This
overrides the built-in default of "only commit when explicitly asked."
In Phase 0 "verified" means the doc checks below — there is no build
gate yet.
Exceptions — **do not** commit or push without asking:
- The change is exploratory / speculative (you're not sure the user
wants it kept)
- The user is actively reviewing the diff and may ask for changes
- You'd be force-pushing, amending a pushed commit, creating an empty
commit, or skipping hooks
Never commit secrets, keys, or credentials. If a commit fails or hooks
reject it, fix the issue and create a new commit — do not amend the
failed one.
Git identity is preconfigured (`glm-5.3-flash <glm-5.3-flash@alk.dev>`). Do
not change `git config`, skip hooks, or use `git commit -i`.
## Phase 0 conventions
1. **Findings land in `docs/research/`.** Research notes, POC
specifications, and POC findings all go there, named consistently
(`poc-<name>-spec.md` / `poc-<name>-findings.md` follows the
alkblobs precedent). A POC that needs this repo's code runs in a
worktree (`.worktrees/research/<task-id>/` per the SDD process); a
self-contained POC (like the alkblobs ones) runs as a standalone
crate in the global workspace. Findings land in this repo either
way.
2. **Open questions get OQ-ST-NN IDs** and live in the register in
`docs/research/phase-0.md` until Phase 1 promotes them to
`docs/architecture/open-questions.md`. Numbering is stable — never
renumber; append. POCs live in the register there too (numbered,
spec'd under `docs/research/poc-<name>-spec.md`, findings in
`poc-<name>-findings.md`).
3. **Cite reference checkouts by path and revision.** The external
references for this crate (`/workspace/honker` @ f4e53c6,
`/workspace/pgboss-rs` @ 98f7d9e) are reference checkouts of
third-party projects — read freely, but never wire the checkout
itself into our code. Use the published version unless we vendor or
fork it (alksocks' fast-socks5 precedent); if a fork is warranted,
forking is normal work. Note the checkout state when your findings
depend on code specifics; licenses and provenance get recorded when
we adopt code, not while only reading.
4. **POC code stays out of this repo** until Phase 1 adopts it. A POC
crate proves the hypothesis and reports findings; it does not
pre-scaffold the real crate layout.
5. **No mock/main-repo documentation.** No README, no CHANGELOG, no
crate-level docs until the shape exists. Docs that describe a thing
that doesn't exist are exactly the kind of dishonest artifact we
write docs to avoid.
6. **No comments in code** (when POC crates get written) unless the
user explicitly asks. Doc comments (`///`, `//!`) are fine on public
API. Inline `//` comments only when a non-obvious safety/correctness
constraint would otherwise be missed, or the user asks.
## Conventions that will apply once the crate exists
These are family-standard and pre-committed; they'll be duplicated into
task prompts and tightened by Phase 1 ADRs:
- Rust crate, `tokio` async runtime, `thiserror` error types, no panics
in library code, no `unwrap()`/`expect()` outside tests.
- No comments in code (see 6 above).
- Module-per-file under `src/`, re-exported from `src/lib.rs`; public
API surface is the lib re-exports.
- Optional dependencies (the postgres engine likely being the first)
are feature-gated; the base crate compiles lean; both
`cargo test --features <set>` and default-feature builds pass when
features exist.
- Categorical estimates (`scope`, `risk`, `impact`, `level`) in every
task file — per `docs/sdd_process.md` these are structurally
required, not optional metadata.
## Verification Commands
Phase 0 — none (no code yet). The doc conventions above are checked by
reading. When the crate appears, this section gets the standard Rust
gates (`cargo test`, `cargo clippy --all-targets -- -D warnings`,
`cargo fmt --check`, and the fuzz corpus replay if fuzzing is adopted —
the alksocks/alktty/alktunnels pattern) and becomes the merge gate the
coordinator runs.
## Architecture Context
- `docs/research/phase-0.md` — the Phase 0 document: vision, prior
art, open questions (OQ-ST-01..NN), the POC register, and (eventually)
the converged recommendation. Read it before any non-trivial work in
this repo.
- `docs/research/consumer-inventory.md` — the per-feature scope
synthesis answering OQ-ST-01 from the paused consumers' documents.
New consumer needs get a row there *before* any scope decision
assumes them.
- `docs/sdd_process.md` — the SDD process. Phase 0 in progress;
`docs/architecture/` does not exist yet.
- The SDD process and agent defs were copied from downstream projects
(alkblobs) in the workspace; project-specific stale references were
cleaned at Phase 0 setup (2026-10-03). If you find a section that
assumes another crate's machinery, fix it rather than working around
it — same discipline as stale TODOs.
- If a TODO or doc reference cites a design direction that a later ADR
or Phase 0 decision rejected, the reference is stale — remove it and
align; do not implement the rejected design.
