* fix: use per-candidate provider for model_fallbacks
Each fallback model now uses its own api_base and api_key from
model_list instead of inheriting the primary model's provider config.
Previously, a single LLMProvider was created from the primary model's
ModelConfig and reused for all fallback candidates — only the model ID
string was swapped. This caused all fallback requests to be routed to
the primary provider's endpoint, making cross-provider fallback chains
non-functional (e.g., OpenRouter primary with Gemini fallback would
send the Gemini request to OpenRouter's API).
Fix: pre-create a per-candidate LLMProvider at agent initialization
time by looking up each candidate's ModelConfig from model_list. The
fallback run closure now selects the correct provider per candidate
via CandidateProviders map, falling back to agent.Provider when no
override is found.

The frontend previously used ws_url returned by /api/pico/token, which
is built from the launcher's own port. Behind a reverse proxy this can
produce incorrect URLs (e.g. ws://localhost:18800 instead of the
proxy's public address).
Since the launcher already proxies /pico/ws on the same port, the
frontend can simply use window.location.host to construct the
WebSocket URL, which is always correct regardless of proxy layers.

- treat `EPERM` from `signal(0)` as “process exists” on Unix
- classify malformed PID files as invalid and auto-remove them during read
- keep cached `pidData` only for transient races and downgrade `running` to `stopped` when the tracked process is gone
- refresh PID data on WebSocket proxy requests and reject stale cached gateway state
- add regression tests for invalid PID files, status downgrade, on-demand PID loading, and stale proxy rejection
SQLite FTS5 bm25() returns negative values where numerically smaller
(more negative) indicates a better match. The official docs state:
"The better the match, the numerically smaller the value returned."
Two comments incorrectly stated "closer to 0 = better match" and
"lower = better match". Updated all rank descriptions to use the
unambiguous "more negative = higher relevance" phrasing.
This matters because these comments are used as tool prompt hints
for LLM agents, and incorrect semantics could lead to wrong ranking
decisions.
- add build tags to exclude context_seahorse.go on mipsle and netbsd
- add context_seahorse_unsupported.go to keep registration and return a clear runtime error
- remove unused indirect dependency github.com/reiver/go-porterstemmer from go.mod and go.sum
- Add -console to Dockerfile CMD so launcher outputs logs to stdout,
making docker logs work as expected
- Remove 127.0.0.1 bind from ports to allow public network access

* feat(seahorse): implement short-term memory engine of seahorse
Add pkg/seahorse/ module implementing a SQLite-backed DAG-based summary
hierarchy for context management, ported from lossless-claw's LCM design:
- types.go + short_constants.go: core types (Message, Summary, Conversation,
ContextItem) and configuration constants (fanout, token targets, thresholds)
- migration.go: idempotent DB schema with FTS5 trigram tokenizer for CJK
- store.go: full SQLite CRUD (conversations, messages, summaries DAG,
context_items with ordinal gap numbering, FTS5 search)
- short_engine.go: Engine lifecycle (NewEngine, Ingest, Assemble, Compact),
session pattern filtering (ignore/stateless glob→regex compilation),
per-session mutex via sync.Map
- short_assembler.go: budget-aware context assembly with fresh tail protection
(32 messages), oldest-first eviction, summary XML formatting, RebuildContextItems
- short_compaction.go: leaf compaction (messages→summary) and condensed
compaction (summaries→higher-level summary), 3-level LLM escalation,
CompactUntilUnder for emergency overflow
- short_retrieval.go: lookupByID, FTS5/LIKE search, recursive expand with
token cap
- context_seahorse.go: agent.ContextManager adapter, registered as "seahorse",
provider↔seahorse message type conversion (ToolCalls, tool_result)
* fix(seahorse): correct 3 adapter bugs in context management
- TokenCount: use full message (Content+ToolCalls+Media) instead of Content-only
- Empty Content: rebuild Content from tool_result Parts when stored empty
- Duplicate summaries: summaries only in Summary field, not in History messages
- Grep: fix SearchResult.Snippet→Content for summaries
- Schema: fix FTS5 SQL uses VIRTUAL TABLE not TEMP TABLE
- TestFTS5SQLConstants: verify FTS5 SQL syntax correctness
- Test: fix flaky TestCompactLeaf
* fix(agent): ingest steering messages into seahorse SQLite
Steering messages were only persisted to session JSONL but not ingested
into seahorse SQLite, causing them to be missing from context assembly.
Added `ts.ingestMessage(turnCtx, al, pm)` call in the steering message
injection block alongside the existing JSONL persistence.
Test: TestSeahorseSteeringMessageIngested verifies steering messages
appear in seahorse SQLite DB after being processed.
* fix(seahorse): address 3 blocking bugs from code review
- Fix resequenceContextItemsTx scan error handling (store.go:850)
Changed `return err` to `return scanErr` to properly propagate scan errors
instead of returning nil (which silently corrupts data)
- Fix sql.NullString for INTEGER column (store.go:847)
Changed `mid` from sql.NullString to sql.NullInt64 since message_id
is INTEGER in schema. Removed unnecessary strconv.ParseInt call.
- Fix compactCondensed fallback deleting non-candidate items
Added ReplaceContextItemsWithSummary method for per-item deletion
when candidates are not contiguous in ordinal space.
Optimized to use range deletion when candidates are consecutive.
* fix(seahorse): pass Budget to Compact for correct condensed threshold
Issue #4 from PR review: When Budget was not passed to seahorse.Compact,
it defaulted to `tokensBefore * 0.75`, making `tokensBefore > budget`
always true and causing condensed compaction to trigger unnecessarily.
Changes:
- context_seahorse.go: Forward Budget from CompactRequest to CompactInput
- loop.go: Pass Budget (ContextWindow) in all 3 Compact calls
- Add test verifying condensed is skipped when tokens < threshold
- Fix lint issues in store.go and store_test.go
* fix(seahorse): add mutex for assembler lazy initialization
Issue #5 from PR review: The check-then-create pattern for e.assembler
was a data race when multiple goroutines called Assemble() concurrently:
if e.assembler == nil {
e.assembler = &Assembler{...}
}
Changes:
- Add assemblerMu sync.Mutex to Engine struct
- Add initAssemblerOnce() using double-checked locking (same pattern as initCompactionOnce)
- Add TestAssemblerLazyInitRace to verify thread-safety
* fix(seahorse): handle non-consecutive depths in selectShallowestCondensationCandidate
Issue #8 from PR review: the loop iterated depth 0, 1, 2... assuming
consecutive keys, but break when key was missing caused deeper depths
to never be checked.
Fix: collect all existing depth keys, sort, then iterate in order.
* fix(seahorse): wrap DeleteMessagesAfterID and appendContextItems in transactions
- DeleteMessagesAfterID: wrap all DELETE operations in a transaction for
atomicity, remove redundant manual FTS delete (handled by trigger)
- appendContextItems: use transaction to fix read-then-write race condition
- Add GetMaxOrdinalTx and resolveItemTokenCountTx for transaction-scoped queries
- Remove unused resolveItemTokenCount function
Fixes PR review issues 6 and 7.
* fix(seahorse): derive readable content from Parts and cap CompactUntilUnder iterations
- Derive readable content from MessageParts in AddMessageWithParts so
FTS5 indexing and summary formatting can access tool call information
- formatMessagesForSummary and truncateSummary now fall back to Parts
when Content is empty, fixing blank summaries for Part-based messages
- Add MaxCompactIterations (20) to prevent CompactUntilUnder infinite
loops; exceeded iterations are logged as warnings
* feat(mcp): store oversized text results as artifacts
* feat(mcp): fix doc
* fix(mcp): preserve raw MCP payload in text artifacts
