opencode 1.18.21-lowmem.17

Resource-bounded fork of anomalyco/opencode — full capability, bounded footprint.

Since lowmem.11: two behavioral hardening rounds, a child-session ordering rework, docs consolidation, and a passive-CPU port. Highlights:

Memory (long sessions)

• Streamed chunks coalesce in the UI before store writes (120 ms), replacing quadratic per-chunk concatenation for every session — including background subagents.
• PartUpdated publishes shallow snapshots instead of deep clones; shell-tool state and plugin events get isolated copies, so delayed clients and plugins can't observe retro-edited parts.
• Deleting a session now truly clears its UI store buckets: messages, parts, diffs, todos, status, permissions, questions, orphans, and eviction bookkeeping — with a tombstone that ignores late events instead of resurrecting them. message.removed drops its part bucket immediately.

Child session list (daily TUI)

• Children reorder only when they receive a message (delegation, task continuation, direct input) — tool rounds, permissions, and compaction never shuffle the list. Newest-50 window, roots excluded, viewed out-of-window children pin in; the run-UI footer reports an honest N of 50.
• Run-mode subagent tabs keep the newest 50 finished agents and revive an evicted one automatically if it asks again.

Passive CPU

• Idle-status dedupe (port of upstream #40984 by zcxGGmu): repeated "session is idle" writes no longer re-broadcast status events to every connected client.

Packaging / docs

• Build round now derives from the highest existing tag, not tag count.
• README is the single authoritative fork document (PORTS.md deleted); port table carries upstream author credit; deferred-ports section records anomalyco#43769/anomalyco#40698 with the tree-shape evidence.

opencode 1.18.21-lowmem.7

No functional changes vs lowmem.6 (publishing/docs/tooling only). First release also distributed on npm (npm i -g opencode-lowmem); adds the release installer script (scripts/fork-install.sh) with SHA-256 digest verification, plus the npm platform-package pipeline (CI workflow + assembler with glibc/musl libc split).

opencode 1.18.21-lowmem.6

Reliability ports: anomalyco#43881 (retry clean-EOF empty provider streams — a flaky gateway can no longer end a turn silently; adds a regression test), anomalyco#42176 (mark finish: "error" on stream failures), anomalyco#43607 (SSE heartbeat comments no longer reset the chunk timeout). PORTS.md gains the durability/rebase policy and upstream watch-list. Recommended round.

opencode 1.18.21-lowmem.5

Fixes from review: upstream permission/question ordering preserved when entering child sessions, and deterministic causal tie-break for same-millisecond session IDs.

opencode 1.18.21-lowmem.4

Conveyor-consistent child-session navigation in the TUI: footer and session list now agree (creation-time order, causal same-millisecond tie-break); tab-cycling wraps through child sessions in the order they were created.

v1.18.21-lowmem.11

Resource-bounded fork of anomalyco/opencode — full capability, bounded footprint.

This round: consolidated clean history (10 feature commits on top of v1.18.21), dropped npm distribution (releases are GitHub-only), hardened payload eviction (failed-hydration re-arm, plugin getter refetch, orphan-part gating), narrowed the clean-EOF retry to truly-empty attempts, and restored array listener semantics in the anomalyco#38939 port.

See the README for the feature table and PORTS.md for the port manifest with upstream credit.

opencode 1.18.21-lowmem.3

Background subagent tabs settle only on opencode's own synthetic injection parts — user/model text can no longer spoof a settlement, and background.extend jobs stay running until the real completion signal arrives.

opencode 1.18.21-lowmem.2

Subagent memory bounds: keep-last-N eviction (50 completed tabs/details; running, pinned, and blocker-holding sessions exempt), oldest-first "conveyor" list ordering so the newest finished agent is always at the bottom. Evicted sessions revive automatically if they later queue a permission or question.

opencode 1.18.21-lowmem.1

Initial lowmem round. Ports of unmerged upstream PRs: anomalyco#39930 (bounded compacted-history hydration), anomalyco#42150 (O(N) delta accumulation), anomalyco#38939 (PubSub listener leak), anomalyco#41950 (config cache isolation). Local customs: diff-patch caps (100KB/patch, 256KB aggregate, metadata-only summaries). Adds scripts/fork-build.sh and the lowmem versioning scheme. See FORK.md and PORTS.md on the default branch.
