Task: Official curve republish: write bootstrapped output as a lineage-stamped market_series

Take the bootstrapping engine's output (one discount factor per tenor for a given config) and publish it as a real, consumable curve: persist each point into market_observations under the bootstrap config's pre-minted output_series_id, and stamp ores_marketdata_observation_lineage_tbl per observation with derivation_config_id=/=derivation_config_version (the bootstrap config that produced it), source_as_of (the raw grid's as-of timestamp the bootstrap read), and source_series_ids (the source_series_id, plus the discount curve's series id when this is a PROJECTION config).

This is the "republish/remap" half of the story's goal: analogous to ores.marketdata's existing raw-producer-tick remap onto the official tenant-scoped stream (Market Data Architecture), except the transform is a bootstrap rather than a passthrough — downstream consumers read output_series_id exactly like any other official series, with no knowledge that it was derived rather than observed.

Depends on the shared derivation-lineage task (the table being written to) and the bootstrapping engine task (the values being written).

• A bootstrap run's output is readable from output_series_id via the exact same as-of query (market_observations_repository::read_as_of()) the raw-grid viewer already uses — no bespoke read path for bootstrapped curves.
• Every published discount-factor observation has a corresponding observation_lineage row; querying "who produced this point and from what source as-of" is a single join, never a guess from a source string.
• market_series.derivation_kind = 'IR_CURVE_BOOTSTRAP' on the output series, matching the shared lineage task's marker convention.
• Re-running a bootstrap (new raw ticks arrived) produces a new observation generation without corrupting or requiring deletion of the prior one — the existing bitemporal/soft-update convention on market_observations already provides this; this task must not special-case it.
• A PROJECTION config's republish is provably sequenced after its discount_curve_config_id's own republish has completed for the same bootstrap cycle.

(Implementation strategy. Written when work starts; key decisions are distilled into the parent story's * Decisions at close, but the plan itself stays — it is the historical record of what we did.)

Trigger: on-demand service call, not NATS-per-tick and not scheduler-only. A bootstrap is a batch recompute over a presumed-complete grid, unlike curve_feed_ingest_loop's per-tick remap; re-bootstrapping mid-grid-publish before every pillar has landed would be wrong. Exposed as curve_republish_service::republish(bootstrap_config_id, as_of), a pure orchestration method callable from a NATS request/reply handler (so shell/CLI/scheduler can all call it the same way) – not gated by any review/approval step; that is a separate follow-on task layered on top of this always-auto-publishing mechanism.

Component placement: ores.marketdata.service, alongside curve_feed_ingest_loop. Confirmed via its own CMakeLists that it already depends on both ores.refdata.core.lib (the bootstrap config/pillar repositories) and ores.analytics.quant.lib (the bootstrap engine) – no new cross-component dependency needed. Neither ores.marketdata.core nor ores.refdata.core alone can see both sides.

Split into a pure resolver + a thin DB-touching orchestrator, mirroring ores.synthetic's ir_curve_template_resolver exactly (its resolve() is unit-tested without a database; its build_ir_curve_refdata_context() is not):

• curve_republish_resolver::resolve_bootstrap_pillars(pillars, refdata_context, raw_rates_by_point_id) – pure, unit-testable. Resolves each pillar's start_tenor_code=/=end_tenor_code to dates via the existing tenor_resolution machinery (resolve_end_date), same T+0 horizon==spot simplification the generation-side resolver already uses, and produces the engine's own bootstrap_pillar list.
• curve_republish_service – reads the config + its pillars (client- side filtered by bootstrap_config_id, no parent-filtered repository method exists yet – same pattern ir_curve_feed_config_handler already uses for ir_curve_template_entry), reads the raw grid via market_observations_repository::read_as_of(source_series_id, as_of), calls the resolver then curve_bootstrap_engine::bootstrap, writes the output points + one observation_lineage row per point.

SWAP fixed-leg schedule needs no new payment-frequency field. ir_curve_bootstrap_pillar (unlike ir_curve_generation_config) has none, and curve_bootstrap_engine only requires each intermediate fixed-leg date to resolve at or before the curve's current bootstrapped frontier (interpolation is fine; exact pillar match is not required – confirmed by reading the engine's own SWAP branch, not just its doc comment). So a SWAP pillar's fixed_leg_dates is simply every prior pillar's own resolved end_date (the config's own tenor grid, already naturally ascending since pillars are processed in sequence_index order) plus this pillar's own end_date – the pillar list is the fixed-leg schedule, no separate concept invented.

Funding-before-Projection build order: for a PROJECTION config, read the discount_curve_config_id's own output_series_id via read_as_of() at the same as_of, convert to vector<bootstrapped_point>, pass as the engine's discount_curve parameter. A discount_curve_required_error (empty/stale/missing coverage) propagates out of republish() uncaught – "fails/defers cleanly", per the engine's own documented contract for this task to honour, not swallowed into a generic error.

market_series.derivation_kind stamping: confirmed the prior task (bootstrap config refdata entities) does not actually mint a market_series row with derivation_kind = 'IR_CURVE_BOOTSTRAP' at config-creation time – its own doc comment describes the intent, but no service code does it (only the test generator sets a random output_series_id with no backing row). Re-opening that task is out of scope here; instead, republish() itself ensures the invariant: read the existing market_series row by output_series_id (it must already exist – a missing row is a config-integrity error, not auto-fabricated, since this service has none of series_type/metric/ qualifier to invent one from) and, if its derivation_kind is still the default OBSERVED sentinel, update it to IR_CURVE_BOOTSTRAP with this config's id=/=version on the first successful republish. Treated as "this republish run claims the series", not a per-run write.

Re-run / bitemporal convention: no special-casing – market_observations_repository::write() and observation_lineage_service::save_observation_lineages() already apply the existing soft-update trigger per their own bitemporal convention; a second republish() call for the same config naturally produces a new generation.

Implementation landed across:

• ores.marketdata.service::curve_republish_resolver (private, pure) – resolve_bootstrap_pillars()=/=resolve_tenor_date(), unit-tested (7 cases, no DB) mirroring ir_curve_template_resolver_tests.cpp's own split.
• ores.marketdata.service::app::curve_republish_service::republish() – the DB-touching orchestrator: reads config+pillars+raw grid+discount curve, calls the resolver then curve_bootstrap_engine::bootstrap, stamps market_series.derivation_kind, writes market_observations=+=observation_lineage.
• republish_curve_request=/=response (ores.marketdata.api) + curve_republish_handler (ores.marketdata.service), wired into application.cpp's existing queue-subscribe block alongside crm_handler – the on-demand NATS entry point, subject marketdata.v1.curve_bootstrap.republish.

Full local build clean. Verified via compass build test_<component> (not raw ctest=/binary invocation, which stalls under this host's concurrent build-lock contention from other environments' worktrees -- see [[id:20D2CB34-4E2F-45D3-8FA2-F1C5B4C7B22F][How do I run the tests?]]): =ores.marketdata.api.tests (14 cases/77 assertions), ores.marketdata.client.tests (28/50), ores.marketdata.core.tests (85/189), ores.marketdata.service.tests (17/59, including the 7 new resolver cases), ores.refdata.core.tests (178/3247, unmodified by this task but re-verified since it shares the build), and ores.analytics.quant.tests (230/12013). All pass.

Not yet done: a manual QA test scenario exercising republish() end to end against a real database (DEPOSIT/FRA/SWAP pillars, a Projection config chained off a Funding config, and a re-run producing a second generation).

Manual QA scenarios (scaffolded via compass add test_scenario, run through the QA Validation Runner panel) that verify this task. Link new ones here as they're created; the scenario doc itself links back via its "Verifies task" field.

Implemented curve_republish_service::republish(bootstrap_config_id, as_of) in ores.marketdata.service: reads an ir_curve_bootstrap_config and its pillars, resolves pillar tenor codes to dates via the existing tenor_resolution machinery, reads the raw grid (and, for a PROJECTION config, its discount curve's own output) via market_observations_repository::read_as_of, invokes curve_bootstrap_engine::bootstrap, and writes the resulting discount factors to market_observations with a matching observation_lineage row per point. Stamps market_series.derivation_kind = 'IR_CURVE_BOOTSTRAP' on first republish (config-creation time never actually did this despite its own doc comment – see * Plan).

Split into a pure curve_republish_resolver (unit-tested, no DB, 7 cases) and the DB-touching service, mirroring ir_curve_template_resolver's own split on the generation side. Exposed on demand via a NATS request/reply handler (marketdata.v1.curve_bootstrap.republish), wired into ores.marketdata.service's application.cpp alongside crm_handler.

All acceptance criteria met except manual QA sign-off, which is deferred: this feature has no Qt UI surface at all today to drive a test_scenario through (confirmed the bootstrap-config task's own doc explicitly left Qt UI out of scope) – filed as a separate Curve builder UI task, alongside the review/sign-off UI task filed earlier in this story. Once that UI exists, this task's own manual verification happens through it rather than a bespoke scenario for a screen that won't be reachable any other way.

Verified via compass build test_<component> (the correct recipe – raw ctest=/binary invocation stalls under this host's concurrent build-lock contention from other environments' worktrees): =ores.marketdata.api/client/core/service.tests (14/77, 28/50, 85/189, 17/59 respectively), ores.refdata.core.tests (178/3247, unmodified by this task but sharing the build), and ores.analytics.quant.tests (230/12013). All green.

Also ran compass build rat (full-repo suite) once, per the pr-raise skill's actual instructions. It failed on ores.iam.core.tests (untouched by this PR) with a hard test-process error, not an assertion failure – the surrounding log showed several queries taking 50-160s where they normally run sub-second (heavy DB contention from other environments' concurrent builds/tests sharing this host). Re-ran ores.iam.core.tests alone immediately after: 91 cases/184 assertions, all green, every case sub-second. Treated as environmental host contention, not a regression – this task's own footprint (ores.marketdata=/=ores.analytics.quant, plus read-only use of ores.refdata) is fully verified green.
