Implemented 2025-11-25 Streamable HTTP polling semantics for POST SSE responses: retain event IDs and retry intervals, wait as instructed, and reconnect with GET plus Last-Event-ID until the originating JSON-RPC response arrives.
Extended the shared SSE parser to expose valid id/retry fields and control-only events so reconnecting consumers do not need to reparse raw lines.
Fixes#8264
- Define a centralized `USER_AGENT` constant in `@oh-my-pi/pi-utils` formatted as `omp/<version>`.
- Replace hardcoded and platform-specific user agent strings across AI providers, catalog scrapers, tools, and search providers with the unified `USER_AGENT`.
- Add unit tests for update-cli binary release distribution gating.
Long write/edit streams made the TUI stutter or freeze for seconds at a
time (ui.loop-blocked warnings, keystrokes starving while the single JS
thread rebuilt previews). Two compounding quadratic paths:
1. parseStreamingJsonThrottled re-parsed the entire accumulated args
buffer on a FIXED 256-byte cadence. The comment claimed this bounded
mid-stream work to O(N), but a constant growth gate still parses an
N-byte buffer N/256 times at O(N) each: O(N^2) with a smaller
constant. The gate now scales geometrically (max(256, len/32)), so
parse points form a geometric progression: O(log N) parses, O(N log N)
total, with mid-stream snapshots staying within ~3% of the stream.
Small buffers keep the exact fixed cadence as before.
2. write.ts formatStreamingContent normalized + split('\n') the WHOLE
accumulated content on every 30Hz reveal tick (renderCall also ran a
full-payload normalize first): O(N) per tick, O(N^2) per stream, per
concurrent writer. The collapsed tail-window path now tracks the
newline count incrementally (append-only resume keyed on the
component's persistent render-state object via WeakMap) and extracts
only the tail window with a backward scan: O(delta + preview lines)
per tick, byte-identical output to the split-based reference. The
expanded (Ctrl+O) path is unchanged in output and skips its
split+join round-trip.
Tests: geometric-gate bounds + freshness + small-buffer cadence in
parse-streaming-json-throttled.test.ts; append-growth/reference-
window/CRLF/trailing-newline/restart battery in
write-streaming-incremental.test.ts. Full write/tool-render battery
(56 tests) and ai streaming-args tests (117 tests) pass.
- The two-child fs.watch/poll choreography deadlocked under parallel test load
(runner killed a dangling probe); the PID-namespace pruning test still covers
the multiprocess audit/rotation file contract.
- mnemopi provider parity 'diagnose, validate, graph' does ~6.7s of real
work under bun --parallel=8 on loaded runners; raised its per-test
timeout to 30s (default 5s flaked twice in three CI runs).
- utils LRUCache updateAgeOnGet drove a 30ms TTL with real 20ms sleeps
(10ms margin); now drives performance.now() via a mocked clock, so the
contract is asserted deterministically with no wall-clock wait.
- A blank run at EOF now breaks the list without consuming the blank,
matching real marked: '- item\n\n' lexes as a tight list plus a space
token instead of a loose list whose raw includes the blank.
- Completes the 17.2.10 mid-document fix; same-marker continuation and
indented item content across blanks are unaffected.
- Added list/blank boundary token-shape tests (verified against marked
v15) since the tui incremental tests compare the lexer to itself.
- A blank line before a non-continuing top-level line (including plain
paragraphs) now closes the list without consuming the blank, so it
always lexes as a separate space token like real marked.
- List token shape no longer depends on the follower's block type,
restoring the TUI streaming lexer's freeze invariant (lex(prefix) ++
lex(tail) == lex(full) under append-only growth).
- A list followed by a paragraph is now tight, not loose, per CommonMark.
- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
Registered live session resume commands with postmortem handling so a
fatal rejection or exception identifies every recoverable agent before
cleanup. Escaped terminal control characters in recovery output.
Account-reset hint evaluated before short retry hints; account-scoped caps rotate on status 403 or undefined (Devin statusless trailer); statusless concurrency caps marked transient; transient same-model retries use the concurrency backoff.
Refuted: quota-worded concurrency caps were already excluded from rotation before the usage-limit text match.
