# API_TODO — trans-membrane OS surface expansion
Status: briefing / design spec for the next round of `uce_host_*` membrane work.
Implementation delegated to the pi agent + sub-agents.
## Why
UCE units run as wasm in a per-request workspace; the **only** way they touch the
OS is via `uce_host_*` hostcalls (see `docs/wasm-runtime-architecture.md`). That
constrained, auditable surface is a feature — it's the security boundary
sysadmins can reason about. The current file API (`file_get_contents` /
`file_put_contents` / `file_append` / `file_exists` / `file_unlink` / `ls` /
`file_mkdir` / `file_mtime` / `path_*` / `cwd_*`) is simple and good but is
**whole-file only** and lacks several OS capabilities real apps need. This doc
widens *what* units can do **within the existing path roots** — not *where*.
## Cross-cutting design principles (apply to EVERY new call)
1. **Requests must complete fast — never block indefinitely.** Every potentially
blocking call takes an explicit timeout/deadline and **fails fast** on expiry
with a clear result, rather than spinning or blocking forever. In particular:
- **File locks expire.** Auto-locking (writes take exclusive, reads wait for
writers) must use a **bounded** wait (deadline, e.g. config
`UCE_FILE_LOCK_TIMEOUT_MS`, sane default ~2000ms). On timeout the op returns
a clear "lock timeout" error — it does NOT hang the request. This applies to
`file_put_contents`/`file_append`/`file_get_contents` and the new streaming
handles below.
- `http_request`, blocking `shell_exec`, `job_await`, etc. all take timeouts.
2. **Fire-and-forget + check back later.** Long work goes to the background and
the request returns immediately with a **job id**; a *later* request (any
worker) checks the outcome. A single host-side **job registry** backs this
(see "Async jobs"). This is the model for background shell, async http, and
any long op — not per-request blocking.
3. **Simple AND versatile.** Prefer one small, composable primitive over many
special cases. Structured inputs/outputs are `DValue` (UCEB across the
membrane). Streaming uses opaque host **handles** (u64). Errors are returned
values (no exceptions in the guest).
4. **One capability per named hostcall** (blocklist granularity — see Future).
Don't bundle unrelated capabilities into one mega-hostcall.
5. **Always policy-gated.** Every path goes through `resolve_guest_file` /
`resolve_guest_write` (roots); handles/stat/rename/etc. gated the same way.
6. **No exceptions/RTTI** in unit-facing code; return values + status DValues.
## API groups to implement
### 1. Streaming / handle-based file I/O (P0 — the keystone)
Whole-file String I/O can't handle large or partial files. Add a handle API.
Locking stays automatic and **lifetime-scoped** (open-for-write = exclusive,
open-for-read = shared, released on `file_close`), with the bounded-wait rule
from principle 1 — this is NOT the old manual lock API, the user never calls a
lock function.
```
u64 file_open(String path, String mode) // "r" "w" "a" "r+"; 0 = error (incl. lock timeout)
String file_read(u64 h, u64 len) // sequential
String file_pread(u64 h, u64 offset, u64 len) // positional
u64 file_write(u64 h, String data) // sequential; returns bytes written
u64 file_pwrite(u64 h, u64 offset, String data)
s64 file_seek(u64 h, s64 offset, int whence) // + file_tell(h)
void file_close(u64 h) // releases lock + fd
```
Keep the existing whole-file `file_get_contents`/`put_contents`/`append` (now
auto-locking) as the easy path.
### 2. Metadata (P0/P1)
```
DValue file_stat(String path) // { exists, size, mtime, ctime, mode, is_dir, is_file, is_symlink }
DValue dir_list(String path) // [ { name, type, size, mtime } ... ]; optional glob/recursive flags
```
(`file_mtime` stays; `dir_list` is the richer `ls` so callers don't N+1 `file_stat`.)
### 3. Structural ops (P1)
```
bool file_rename(String from, String to) // atomic replace; enables write-temp-then-rename
bool file_copy(String from, String to) // host-side, preserves mode
bool file_truncate(String path, u64 size) // (or on a handle)
bool dir_remove(String path, bool recursive)
```
### 4. Niceties (P2)
```
String file_temp(String prefix) // race-free temp file under a write root (mkstemp)
bool file_chmod(String path, u32 mode)
bool file_symlink(String target, String linkpath); String file_readlink(String path)
// durability: file_put_contents/file_write gain an optional fsync flag/variant
```
### 5. Outbound HTTP (with TLS) (high value)
`socket_*` is raw TCP only — no secure outbound. Add a real client:
```
DValue http_request(DValue req) // req: { method, url, headers{}, body, timeout_ms, follow_redirects }
// -> { status, headers{}, body, error } (TLS/https supported)
u64 http_request_async(DValue req) // -> job_id (see Async jobs)
```
### 6. Crypto (extended) (high value)
`hash.h` has sha1 + rng only.
```
String sha256(String data); String sha256_hex(String data)
String hmac_sha256(String key, String data) // + _hex
String base64_encode(String data); String base64_decode(String b64)
String random_bytes(u64 n) // CSPRNG
bool crypto_equal(String a, String b) // constant-time compare
```
### 7. Shell (extended + background) (high value)
Current `shell_exec` is blocking + output-only.
```
DValue shell_exec(DValue spec) // spec: { cmd, stdin, env{}, timeout_ms } -> { exit_code, stdout, stderr, timed_out }
u64 shell_spawn(DValue spec) // background -> job_id; non-blocking; request returns immediately
```
(Keep a simple `shell_exec(String)` convenience overload returning stdout.)
### 8. Async jobs (the unifying "check back later" primitive)
Host-side job registry, survives the spawning request, reachable from any later
request/worker by id.
```
DValue job_status(u64 job_id) // { state: pending|running|done|failed, ... }
DValue job_result(u64 job_id) // blocks up to a small default; { done, ... , result }
DValue job_await(u64 job_id, u64 timeout_ms) // bounded wait; returns even if not done (state=running)
bool job_cancel(u64 job_id)
```
`shell_spawn` and `http_request_async` produce job ids consumed here. Jobs have a
TTL and are reaped; results are retrievable until collected or TTL expires.
## Explicitly OUT of scope (declined)
- DNS resolution API, UDP sockets, `setenv` / environment mutation.
## Future (design influences now, NOT implemented here)
- **Configurable trans-membrane blocklist.** A server config will let sysadmins
disable specific hostcalls by name (e.g. turn off `shell_exec`, `http_request`)
to harden a deployment. This is WHY principle 4 (one capability per named
hostcall) matters — keep the granularity clean so each is independently
gateable. A blocked call should return a clear "disabled by policy" error.
- **Native app extensions.** Longer term: let app developers ship their own
native compiled modules (`.so` living in the site tree) that units can call
across the membrane — a per-app plugin mechanism. Out of scope now, but the
hostcall/membrane shape should not preclude a future generic
"call host extension" dispatch.
## Implementation notes
- Each call = a discrete `uce_host_*` hostcall: add to `src/wasm/core_hostcalls.syms`,
register in `src/wasm/worker.cpp`, declare/implement the wasm-core wrapper in
`src/lib/sys.cpp` (+ header) mirroring existing hostcalls (sized-buffer for
bytes, sized-DValue/UCEB for structured returns).
- Reuse native impls where they exist; policy-gate every path.
- Each group lands suite-gated (`run_cli_tests --include-wasm-kill`, 0 failed) on
the build host; add tests + doc pages per new function (function pages, and
method/`2_` pages where a class gains methods).

# DOCS-TODO — `/doc` documentation overhaul
Briefing for the doc-system overhaul. Read this fully before touching anything.
The approved design and the two locked decisions are: **(1) examples are LIVE and
SELF-VERIFYING** — real UCE code executed at render time, showing source + actual
captured output, gated by the test suite; **(2) FULL SWEEP** of all 257 pages.
The docs live under `site/doc/`:
- `index.uce` — the renderer (index + per-page detail view).
- `lib/doc_page.h` — page parsing (`load_doc_page`) + label/kind helpers.
- `style.css` — theme + layout.
- `pages/*.txt` — 257 page source files (the corpus).
- `areas/*.txt` — area groupings; first line is the area title, following lines
are page slugs (or `>area` references) that populate the index sidebar.
- `search.uce`, `singlepage.uce` — search + single-page render.
## Why this work exists (the problems)
- **Title bug:** 15 pages carry a `:title` that literally repeats the raw filename,
so `0_StringList` renders as "0_StringList" instead of "StringList". The `:title`
override defeats the prefix-stripping label logic already in `doc_page.h`
(`doc_default_title` / `doc_index_label` / `doc_method_label`).
- **31 slop/stub pages:** the newest APIs (`file_*`, `crypto_equal`, `sha256*`,
`hmac*`, `random_bytes`, `http_request*`, `job_*`, `shell_spawn`) are throwaway
`# name` + one-line markdown with NO `:sig`/`:params`/`:see`/`:content`.
- **134 of 257 pages have no code example.** We want PHP-manual-style
code-to-output examples on EVERY page.
- **Sidebar overflow:** long monospace identifiers in the 280px index sidebar and
220px detail sidebar have no wrapping → they spill.
- **Relevancy:** pages lead with cross-membrane mechanics and "Related Concepts"
PHP/JS filler instead of usage; cross-references between related pages are missing.
## Principles for every page
1. **Usage first.** The opening `:content` sentence says what the function does and
when you'd reach for it — in plain terms. No membrane/ABI talk up top.
2. **A real example, always.** Every page has at least one `:example` whose output
is produced by actually running it. Examples are the primary teaching tool.
3. **Cross-link.** Every page's `:see` references its area (`>area`) and its closest
sibling APIs, so the reader is never left to search alone.
4. **Demote the drivel.** Cross-membrane behavior, lock semantics, and PHP/JS
equivalents are at most a short trailing note — never the body. Delete filler
that teaches nothing.
---
## Phase 1 — Infrastructure (do this FIRST, verify on host before any content)
### 1a. Title bug
- In `lib/doc_page.h` `load_doc_page`: when a `:title` value, trimmed, **equals the
page slug**, ignore it (leave `result.title` empty) so the renderer falls through
to `doc_default_title`, which already strips `0_/1_/2_/3_` prefixes and renders
`Class::method` for `2_*`.
- Strip the 15 redundant `:title` blocks from their pages (`0_StringList`, `cli_arg`,
`cli_input`, `list_filter`, `list_map`, `map`, `request_base_url`,
`request_query_path`, `request_query_route`, `request_script_url`,
`route_path_is_safe`, `route_path_normalize`, `route_path_sanitize`, `ucb_encode`,
`ucb_decode`).
- Fix garbage `:sig` lines on struct pages (e.g. `0_StringList`'s sig is literally
`0_StringList`): give struct pages a real one-line type summary or drop the sig box.
### 1b. Live example mechanism — EXACT SPEC
Primitives (already confirmed to exist): `unit_compile(path)`, `unit_render(path)`,
`ob_start()`, `ob_get_close()`. Relative paths in the doc unit resolve against
`site/doc/`.
- **Parse:** add `:example` handling to `load_doc_page` → `DocPage.examples`
(a list; multiple `:example` blocks per page allowed). Capture the raw body lines
verbatim (this is both the displayed source AND the executed code).
- **Materialize:** for each example, write the body wrapped in a minimal unit to a
**stable** path `examples/_gen/<slug>_<n>.uce`:
```
RENDER(Request& context)
{
<example body>
}
```
Write **only if the content changed** (compare to existing file) so the runtime's
compiled-unit cache stays warm. The `_gen` dir must be writable by the worker
(www-data) — created/`chown`ed once on the host (see Setup below).
- **Execute + capture:** `unit_compile("examples/_gen/<slug>_<n>.uce");` then
`ob_start(); unit_render("examples/_gen/<slug>_<n>.uce"); String out = ob_get_close();`
- **Render:** an "Example" `doc-section` showing the source block, then the captured
output beneath it under an "Output" label (PHP-manual style). If the example
traps or output is empty, **surface that visibly** (do not swallow it) — a broken
example must be obvious so the gate catches it.
- Examples must be **self-contained and deterministic** — no wall-clock/random output
shown as canonical (if a function is inherently non-deterministic, show a
representative call and describe the shape, or seed it). The gate asserts presence
of an output block + absence of an error marker, not an exact value, EXCEPT where
the value is deterministic.
### 1c. Sidebar + example CSS (`style.css`)
- Add `overflow-wrap: anywhere; word-break: break-word;` to `.category li a`,
`.func-item a`, and `.sidebar-card div`.
- Style the example Output block so it's visually distinct from the source (subtle
border + an "Output" label), reusing existing `--bg-code`/`--border` tokens.
### 1d. Format spec page
- Create `pages/3_Documentation format.txt` (an `info` page) documenting the canonical
page template below, so the format is self-describing inside the docs.
### Canonical page template
```
:sig
<one or more real C++ signatures, exactly as declared>
:params
<name> : <what it is>
return value : <what comes back>
:content
<Usage-first prose. What it does, when to use it. 2–5 tight sentences.>
:example
<runnable UCE code that print()s something illustrative>
:see
><area>
<closest sibling API slugs>
```
Optional short trailing note in `:content` for membrane/PHP-JS equivalence — one line,
not a section. No `:title` unless it differs from the derived label.
### Setup (host, one-time, before content work)
```sh
ssh root@10.4.2.110 'cd /Code/uce.openfu.com/uce && mkdir -p site/doc/examples/_gen && chown -R www-data:www-data site/doc/examples/_gen && chmod 775 site/doc/examples/_gen'
```
---
## Phase 2 — Content sweep (batched by area; one area = one reviewable batch)
For each area file in `site/doc/areas/` (string, sys, types, sqlite, mysql, memcache,
session, websocket, task, time, uri, regex, ob, markup, socket, noise, runtime), bring
every listed page to the canonical template:
1. **Convert the 31 stubs** to full structured pages.
2. **Add a live `:example`** to every page missing one (≈134), each verified to render
real output.
3. **Repair `:see`** — area link + sibling links on every page; demote membrane / PHP-JS
filler to a one-line note.
4. **Cull dead pages** — remove `concat.txt` ("Removed. Not a current API") and audit
internal-only helpers (e.g. `json_consume_space`) for removal; also remove culled
slugs from the relevant `areas/*.txt`.
Per-batch bar: every touched page renders cleanly, its example produces real output,
and the suite stays green.
---
## Phase 3 — Gate
- Add a `site/tests/cli_runner.uce` regression test that renders **every** `?p=` page
and asserts HTTP 200, no error/trap marker, and (for pages with `:example`) presence
of a non-error Output block.
- Full host gate (this is the ONLY place builds/tests run — the sshfs mount is
edit-only, no WASI SDK on the client):
```sh
ssh root@10.4.2.110 'cd /Code/uce.openfu.com/uce && bash scripts/build_core_wasm.sh && bash scripts/build_linux.sh && systemctl restart uce.service && sleep 3 && bash scripts/run_cli_tests.sh --include-wasm-kill'
```
Expect the current 91 to grow by the new doc gate(s), 0 failed.
## Hard rules (non-negotiable)
- **NEVER `git commit`/push/tag.** Not pi, not its subagents, not anyone. Leave a clean
working tree and report.
- **Always run the real host gate** (`bash scripts/build_core_wasm.sh && bash
scripts/build_linux.sh && systemctl restart uce.service && ...`) and trust only its
output. `g++ -fsyntax-only` / client-side builds do NOT count — there is no WASI SDK
on the client and the doc unit must actually render.
- Sub-delegation model is exactly `gpt-5.3-codex-spark`.
- Verify the example mechanism end-to-end on the host BEFORE authoring content against
it — content written against an unproven mechanism is wasted.

# /doc Documentation Overhaul
## Objective
Implement the DOCS-TODO.md overhaul for the UCE `/doc` system on the sshfs source-of-truth tree, verifying builds/tests only on `root@10.4.2.110:/Code/uce.openfu.com/uce`.
## Success Criteria
- [x] Phase 1 infrastructure complete: title bug, live examples, CSS, format spec page.
- [x] Example mechanism verified end-to-end on host before broad content authoring.
- [x] Phase 2 example coverage sweep: all doc pages now have `:example`; filler/code-fence cleanup applied, resource-bound fences only.
- [x] Phase 3 doc rendering gate added.
- [x] Current host gate passes with 0 failed.
## Current State
- Status: verifying; Phase 1 + gate complete, StringList conversion complete, Phase 2 example/filler sweep complete.
- Last updated: 2026-06-16
- Source of truth: `/root/mount_ssh/uce-dev-root-htdocs-uce`
- Runtime/live target: `root@10.4.2.110:/Code/uce.openfu.com/uce`
## Goal Tree
Legend: `[ ]` not started, `[~]` in progress, `[x]` done, `[!]` blocked, `[-]` superseded
- [x] G1: Phase 1 infrastructure
- Done when: live examples render source/output on the host and title/sidebar/spec fixes are in place.
- Verify: host build/restart/curl spot check.
- [x] G1.1: Fix title override behavior and redundant title blocks.
- [x] G1.2: Add `:example` parser, materializer, executor, renderer.
- [x] G1.3: Add sidebar/example CSS.
- [x] G1.4: Add documentation format page.
- [x] G1.5: End-to-end host verification with one page example.
- [x] G2: Phase 2 content sweep by area
- Done when: all 257 pages match canonical template and examples render.
- Verify: area batch curls and host gate stays green.
- [x] G3: Phase 3 CLI doc gate
- Done when: CLI runner checks every doc page and examples.
- Verify: full host gate passes.
## Execution Queue
1. G2 area batching/delegation now that the mechanism is proven.
2. Keep the host suite green after each area batch.
## Decisions
- 2026-06-16: Follow DOCS-TODO.md exactly; no git commit/push/tag.
## Evidence and Verification Log
- 2026-06-16: Read `DOCS-TODO.md`, `site/doc/lib/doc_page.h`, `site/doc/index.uce`, `site/tests/cli_runner.uce`.
- 2026-06-16: Host setup/build/restart/curl for `2_DValue_filter` showed source and captured output `Ada`.
- 2026-06-16: Full host gate passed: `Summary: 349 passed, 0 failed, 0 skipped`.
- 2026-06-16: Converted retiring `list_unique/list_sort/list_some/list_every/list_find` free functions to `StringList` methods, updated callers and method docs; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
- 2026-06-16: Added live examples across types, string, regex, time, markup, noise, uri, and session area pages; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
- 2026-06-16: Added `:example` blocks to all remaining doc pages, removed full PHP/JS Related Concepts filler, removed duplicate content code fences except resource-bound pages; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
## Change Log
- 2026-06-16: Created initial goal tree.
